The home screen, also referred to as the homescreen or start screen, is the primary interface displayed when a mobile device such as a smartphone or tablet is unlocked or powered on, serving as the central hub for user interaction and app access.[1] It typically consists of a customizable grid of application icons, widgets that provide live updates and quick functionalities, shortcuts to settings or notifications, and background elements like wallpapers or themes.[2]In modern mobile operating systems, the home screen has evolved to emphasize personalization and efficiency, allowing users to rearrange icons, create folders, and integrate dynamic content without needing to open individual apps.[3] For instance, in Android, the home screen supports app widgets as miniature views of an app's key data, enabling at-a-glance information like weather updates or calendar events directly on the interface.[4] Similarly, iOS incorporates widgets on the home screen to deliver glanceable content, such as news feeds or fitness metrics, alongside app icons arranged in a grid layout without a separate app drawer. As of iOS 18 (released in 2024), iOS has introduced greater customization, including freeform icon placement and theming options.[5][6] These features distinguish the home screen from earlier mobile interfaces, which were more static, by fostering seamless navigation and integration with device ecosystems.[7]Platform variations, such as Android's support for multiple home screen pages, third-party launchers, and iOS's grid-based design with built-in quick actions, are detailed in subsequent sections. Both systems ensure the home screen remains the default entry point, adapting to user preferences through gestures like swiping for additional pages or searching via integrated spotlights.[8][9]
Introduction
Definition and Purpose
The home screen is the default graphical user interface presented by an operating system immediately after device unlock, acting as the root or primary landing page for user engagement across mobile, tablet, and desktop environments. It serves as the central hub enabling access to applications, system settings, and essential OS functions, providing an organized starting point for daily interactions.[1][10]The primary purposes of the home screen include streamlining quick navigation to core applications and tools, supporting user personalization to tailor the interface to individual preferences, and incorporating status indicators or notifications for real-time awareness of device activity and alerts. These functions establish it as a foundational element in operating systems, balancing efficiency with accessibility.[2][11][12]Early implementations of the home screen relied on static grid layouts to arrange access points in a fixed manner, whereas contemporary designs have evolved to include dynamic, gesture-based interactions for more fluid navigation and responsiveness.[13]It is distinct from the lock screen, which precedes it and mandates authentication for security while limiting interactions to basic displays like time and notifications, and from the app drawer, a supplementary storagemenu in certain systems that catalogs all installed applications without emphasizing customized prioritization.[11][14][15]
Role in User Experience
The home screen significantly enhances usability by minimizing cognitive load through intuitive layouts that prioritize quick access to core functions. Users typically arrange icons based on frequency of use and functional relatedness, allowing for one-tap launches of essential apps and reducing the mental effort required to navigate the device. This organization strategy streamlines daily interactions, as evidenced by analyses of over 1,400 home screen screenshots from more than 130 participants, which revealed consistent patterns in icon placement to optimize efficiency.[16]From a psychological perspective, the home screen facilitates habit formation by embedding apps into users' routines through strategic placement, thereby influencing behavior and productivity. Prominent positioning of frequently used applications encourages habitual checking and engagement, integrating device use into waking and evening patterns, such as morning news reading or evening entertainment. Studies on platforms like WeChat and Line, used by over a billion individuals as de facto home screens, demonstrate how this constant accessibility fosters "permanently online, permanently connected" behaviors, with both positive effects on satisfaction and potential negatives like increased stress.[17]Accessibility features integrated into home screens ensure inclusive user experiences for individuals with disabilities, such as visual or motor impairments. Options like enlarged icons and adjustable display sizes accommodate low vision by improving visibility and touch accuracy, while voice navigation tools enable hands-free interaction. For example, Android's Accessibility Menu offers large on-screen buttons for easier control, and iOS's VoiceOver provides auditory descriptions of screen elements, allowing users to swipe and explore without relying on sight. These adaptations promote independence and reduce barriers in device operation.[18][19]The role of the home screen in user experience is quantifiable through metrics like task completion time and user retention, which are directly linked to design principles such as simplicity and personalization. Efficient layouts correlate with shorter times to perform routine actions, like launching apps or accessing notifications, thereby boosting overall satisfaction and encouraging sustained device use.
Core Components
Icons and Shortcuts
Icons and shortcuts serve as the primary static visual elements on the home screen, enabling quick access to applications and specific actions without navigating deeper into the operating system. App icons typically consist of a graphical symbol representing the app, often paired with a text label below it for identification, arranged in a structured grid layout to optimize screen real estate on mobile devices.[20][21] Folders allow users to group multiple app icons into collapsible containers, reducing clutter by stacking related apps, while shortcuts provide direct links to intra-app functions, such as initiating a phone call to a specific contact or opening a particular document.[22][23]Design standards for icons emphasize simplicity, recognizability, and consistency to ensure intuitive user interaction across platforms. On iOS, app icons measure 180 × 180 pixels at 3x resolution for high-density displays, adhering to the Human Interface Guidelines (HIG) which recommend streamlined shapes, minimal detail, and the use of SF Symbols for system-provided icons to maintain visual harmony.[20][24] In Android, icons follow Material Design principles, utilizing adaptive formats with a 48 dp foreground layer that masks to circular, squircle, or rounded square shapes depending on the launcher, ensuring scalability and theme adaptability.[25][21] Grid arrangements vary by device and OS: iOS employs a standard 4 × 6 layout for iPhone home screens, accommodating up to 24 icons per page, while Android launchers commonly use 4 × 5 or 5 × 5 grids, adjustable via settings for user preference.[26][21]Functionality revolves around user manipulation to personalize the layout, with dragging as the core mechanic for repositioning. On iOS, users long-press the home screen background to enter jiggle mode, allowing icons to be dragged to new grid positions, dropped into folders, or removed; pinning occurs by placing an icon on the home screen from the app library, and unpinning involves dragging it off or to the library.[27]Android mirrors this with a long-press on an icon or empty space to initiate drag mode, enabling rearrangement, folder creation by dragging one icon over another, and pinning via the same placement from the app drawer.[23]Icon appearances update automatically with app versions, reflecting developer-submitted changes that comply with platform guidelines, such as new artwork or adaptive variants, without disrupting the grid structure.[20][25] Shortcuts, limited to four per app on both platforms, appear in contextual menus—via touch-and-hold on iOS or long-press on Android—facilitating actions like quick app tasks while maintaining static icon integrity.[28][23]When the home screen exceeds grid capacity due to numerous icons or folders, systems implement overflow handling through pagination or scrolling mechanisms to manage limited space. iOS adds new pages by dragging icons beyond the current screen edge, allowing horizontal swiping across multiple pages, with the App Library serving as a searchable overflow for all apps beyond the first few screens.[29] Android launchers similarly create additional swipeable pages for excess items, with folder depth capped (e.g., 15 pages in iOS folders) to prevent excessive nesting, ensuring navigability despite screen constraints.[26] This approach balances accessibility with the finite display area, typically 5-6 inches diagonally on smartphones.[21]
Widgets and Dynamic Elements
Widgets represent interactive, resizable modules on the home screen that deliver real-time or periodically updated information and controls from associated applications, enabling users to access key data without launching the full app.[4][5] These components typically include informational displays such as weather forecasts showing current conditions, calendar previews listing upcoming events, or music players indicating playback status and offering basic controls.[4][5] Other types encompass collection-based widgets for browsing items like news feeds or photo galleries, control-oriented ones for quick actions such as toggling smart home devices, and hybrid variants combining multiple functions.[4]Implementation of widgets involves mechanisms to source data directly from the parent application, often through configurable user preferences like selecting a specific city for a weatherwidget or stock symbol for financial previews. Updates occur via scheduled refreshes, such as periodic timeline entries managed by the system or app-initiated pulls using services like AlarmManager in Android, ensuring content remains relevant without constant polling.[4] Interactions are primarily touch-based, with tappable areas expanding to deeper app views or executing inline actions like marking a task complete, while supporting limited gestures such as vertical scrolling for collections.[4][30]Widgets enhance information density on the home screen by providing glanceable updates, such as clock widgets that automatically sync with the device's time zone, reducing the need to navigate menus for routine checks.[5] This approach fosters efficient user engagement, allowing immediate visibility of dynamic content like email previews or fitness metrics directly alongside static icons that primarily serve as launch points.[4]Frequent refresh mechanisms, however, can contribute to battery consumption by relying on background processes to fetch and render updates, particularly for data-intensive widgets involving location or network access.[31]Privacy concerns arise from the permissions required for widgets to access app data, potentially exposing sensitive information like calendar events or personal notifications on the home screen unless users restrict visibility through device settings.[32]
Customization and Alternatives
Built-in Customization Options
Built-in customization options for home screens allow users to personalize layouts and appearances using native tools provided by major mobile operating systems, enhancing usability without requiring external software. These features typically include selecting wallpapers, rearranging icons, applying themes such as light or dark modes, and adjusting grid sizes to fit individual preferences. For instance, in iOS, users can touch and hold the home screen background to enter edit mode, enabling icon dragging, page addition or removal, and tint application to icons for color customization. Similarly, Android's Pixel Launcher permits long-pressing an empty space to access wallpaper and style options, where users select images, apply color palettes derived from the wallpaper, and choose grid sizes ranging from small (5x5) to large (3x5 or similar configurations). As of Android 16 (released June 2025), the system automatically applies themes to app icons for a more cohesive home screen experience.[33][29][34][35][35][36][37]Layout modifications further enable flexible organization, such as creating multiple pages or screens, establishing persistent docks for key icons, and integrating basic gestures like swipes for navigation. In iOS, the bottom dock holds up to five apps for quick access across pages, and users swipe left or right to navigate multiple home screens, with iOS 18 (released September 2024) introducing free-form icon placement allowing blank spaces between items; this feature continues in iOS 19. Android supports adding home screen pages by dragging icons beyond the current page boundary, maintaining a favorites row at the bottom as a dock, and using swipe gestures to switch pages or access the app drawer. These tools promote efficient icon grouping into folders, with iOS and Android allowing drag-to-folder creation.[34][29][38][36][35][39]System-level options extend personalization to visual and interactive elements, including font adjustments, animation speeds, and accessibility features like icon scaling. iOS provides light/dark mode toggles that automatically adjust based on time or schedule, with accessibility settings for larger text and reduced motion animations to minimize jiggling effects during rearrangements. Android's display settings allow dark theme activation for battery savings and font size scaling, alongside developer options for tweaking animation durations and accessibility toggles for larger touch targets. Font changes are generally limited across platforms to system defaults, though Android and iOS offer size scaling for better readability.[40][41][42]Despite these capabilities, operating systems impose limitations on customization to preserve interface consistency, security, and brand identity, restricting deep theming such as wholesale icon replacements or arbitrary UI element alterations. iOS, for example, confines icon changes to tints and sizes without allowing custom images unless using built-in Shortcuts, ensuring a uniform look across devices. Android's stock launcher offers grid and color adjustments but defers advanced theming to manufacturer skins or third-party options, with core system elements protected from modification. These constraints balance user freedom with the need for a stable, intuitive experience.[34][43][35]
Third-Party Home Screen Replacements
Third-party home screen replacements primarily refer to applications and custom operating system distributions that supplant the default Android launcher, enabling users to overhaul the interface beyond native customization options. These solutions are predominantly available on Android devices, where the open ecosystem allows such modifications, unlike more locked-down platforms like iOS. Launchers, such as Niagara Launcher and Action Launcher, function as standalone apps that users can install and designate as the default home screen, while custom ROMs like LineageOS provide a full system replacement that includes a revamped user interface.[44][45][46]Key examples of launchers include Niagara Launcher, emphasizing a minimalist, list-based layout, and Action Launcher, which emulates Pixel-like features with adaptive icons. Custom ROMs, such as LineageOS and Evolution X, offer integrated UI overhauls, often incorporating stock Android aesthetics with added personalization layers as of Android 16 support in late 2025. These replacements support advanced features like gesture-based navigation—for instance, swipe gestures to access app drawers or notifications in Action Launcher and Smart Launcher 6—and sophisticated theming options, including icon packs, color schemes, and animations that extend to widgets and transitions.[44][45][47][46][48]Installation for launchers is straightforward and does not require rooting; users download them from the Google Play Store, launch the app, and select it as the default home screen via Android settings, ensuring compatibility with most devices running Android 5.0 or later. In contrast, custom ROMs demand more technical intervention, including unlocking the device's bootloader, installing a custom recovery like TWRP, rooting via tools such as Magisk, and flashing the ROM image, which limits compatibility to supported devices—LineageOS, for example, covers over 200 models from various manufacturers but excludes those with locked bootloaders like certain Honor or Huawei phones. Both types integrate with core OS functions, such as app launching and notifications, though custom ROMs may alter system-level behaviors for deeper control.[44][49][46][47]The primary benefits of these replacements lie in their flexibility, allowing users to remove manufacturer bloatware, implement gesture-driven workflows for faster navigation, and tailor layouts for enhanced productivity—such as Niagara Launcher's adaptive app suggestions or Microsoft Launcher's cross-device synchronization with Windows ecosystems. Custom ROMs further extend device lifespan by providing ongoing updates beyond official support, enabling features like Unix utilities in LineageOS for power users. However, risks include potential stability issues, such as app crashes or delayed animations in third-party launchers on Android 16, and more severe concerns with custom ROMs, including bricking the device during installation, voiding warranties, and introducing security vulnerabilities from unverified sources or delayed patches. Reputable launchers from the Play Store mitigate malware risks through Google's vetting, but custom ROMs require user-managed security, potentially exposing devices to exploits if not updated promptly.[45][44][47][46][50]Popular use cases among power users involve achieving minimalism, as seen with Olauncher’s clutter-free design for focused daily interactions, or boosting productivity through customizable grids and search integrations in Action Launcher, particularly on tablets or low-spec devices. These tools appeal to enthusiasts seeking radical personalization without hardware upgrades, though they demand familiarity with Android's ecosystem to avoid disruptions.[45][44]
Platform Variations
Mobile Operating Systems
In iOS, the home screen is managed by the SpringBoard process, which serves as the primary interface for displaying and interacting with app icons, widgets, and system elements on iPhone and iPad devices. SpringBoard handles tasks such as icon arrangement, app launching, and transitions between the home screen and other views, ensuring a consistent touch-based experience optimized for mobile hardware. Unlike many competing systems, iOS employs a fixed grid layout for app icons, traditionally aligning them in a rigid 4x6 or similar structure across multiple pages without a dedicated app drawer; users organize apps directly on these pages using folders or search, promoting a curated and personalized front-facing interface. Starting with iOS 18, users can further customize the appearance of icons and widgets by applying light, dark, tinted, or clear styles, and selecting larger icon sizes for enhanced personalization while preserving the grid alignment.[34] This approach changed slightly with the introduction of the App Library in iOS 14, which provides a categorized, searchable backend view of all apps accessible by swiping left from the last home screen page, effectively serving as an optional organizational layer without disrupting the primary grid-based design.[29]Control Center integrates seamlessly with the iOS home screen as a quick-access overlay for toggling settings like Wi-Fi, brightness, and media playback, invoked by swiping down from the top-right corner of the screen on devices without a Home button. This gesture-based access keeps essential controls one step away from the home screen, enhancing usability without cluttering the icon grid, and users can customize its layout and pages in iOS 18 and later for added personalization. SpringBoard's role extends to coordinating these overlays, ensuring smooth animations and state management during interactions.Android's home screen implementation varies significantly due to its open architecture, where the default launcher—such as the Pixel Launcher—provides a flexible foundation that supports third-party replacements for extensive customization. Central to this is the app drawer, a swipe-up or dedicated icon-accessible panel that lists all installed applications in a scrollable view, separating them from the customizable home screen pages to reduce clutter and enable users to pin frequently used apps as shortcuts or icons. Overlays like Google Discover (evolved from Google Now) integrate directly into the home screen experience, appearing as a left-swipe feed of personalized cards for news, weather, and Assistant suggestions, powered by machine learning to surface relevant content without leaving the launcher interface.Original equipment manufacturers (OEMs) further differentiate Android home screens through skinned launchers, exemplified by Samsung's One UI, which builds on the AOSP (Android Open Source Project) framework to offer intuitive customizations like resizable widgets, edge panels for quick app access, and a unified app drawer with alphabetical scrolling. One UI emphasizes a "hands-on" design philosophy, adapting the home screen for one-handed use with larger touch targets and dynamic theming that syncs colors from wallpapers to icons and folders, while maintaining compatibility with gesture navigation for seamless transitions.[51]Other mobile operating systems introduce unique home screen paradigms, such as Huawei's HarmonyOS, which prioritizes distributed device collaboration through service widgets—compact, interactive cards pinned directly to the home screen for real-time data from connected ecosystem devices like smartwatches or cars, in various sizes and formats for flexible layouts. Historically, Microsoft's Windows Phone featured live tiles on its start screen, dynamic icons that updated in real-time with notifications, weather, or social updates, creating an at-a-glance dashboard that influenced later widget evolutions in mobile UI design.[52]Across mobile operating systems, common trends include the evolution of gesture navigation, which has shifted from button-based controls to fluid swipes—Android's pill-shaped home gesture in version 10 and beyond allows returning to the home screen via an upward swipe from the bottom, reducing on-screen clutter and maximizing display real estate for immersive experiences. Similarly, notification shading, a pull-down panel originating in Android for aggregating alerts and quick settings, has become a standard in touch-first interfaces, with iOS's Notification Center offering parallel functionality through a top-swipe gesture to centralize messages and badges without interrupting home screen flow. These developments reflect a broader push toward intuitive, edge-to-edge interactions tailored to mobile form factors.
Desktop and Tablet Environments
In desktop and tablet environments, the home screen equivalent often manifests as a centralized interface for launching applications, accessing system functions, and managing multitasking, adapted for larger screens and productivity workflows. Unlike mobile paradigms, these setups emphasize multi-window management, customizable panels, and integration with keyboard/mouse inputs to support extended sessions.[53]The Windows Start Menu serves as the primary home screen access point in Windows 11. As of the November 2025 Patch Tuesday update, it features a centered taskbar icon that opens a redesigned, responsive menu with a single vertically scrollable surface integrating pinned apps, recommendations, and search. The pinned section allows users to arrange, group into folders, and resize up to a dynamic number of app icons (adapting to screen resolution), without live updates as dynamic tiles from Windows 10 were removed in favor of static pins. Search remains prominent, supporting natural language queries for apps, settings, and files with filtered results. The recommendations area surfaces recently added or frequently used items, toggleable for privacy, now seamlessly blended in the scrollable layout with options for category or grid views.[54][55][53]On macOS, the Dock functions as a persistent home screen strip along the screen edge, providing one-click app launching through magnified icons that indicate open applications with dots. Users can pin favorite apps, adjust size and position (left, bottom, or right), and enable auto-hiding for a cleaner workspace, with recent apps suggested at the end for fluid access.[56] Mission Control complements this by offering an overview of all open windows and full-screen apps, displayed as thumbnails in a Spaces bar for seamless switching—users swipe up or use keyboard shortcuts to navigate, drag windows into Split View with full-screen apps, or rearrange spaces per display.[57] This setup prioritizes gesture-based multitasking, grouping windows by application to reduce clutter on larger displays.[56]Linux desktop environments like GNOME and KDE provide highly modular home screen alternatives through customizable panels and extensions. In GNOME Shell, the top panel acts as a fixed bar for status indicators and app menus, extensible via JavaScript-based extensions that add widgets for weather, system monitors, or custom search providers, replacing legacy applets while allowing interface modifications without core code changes.[58] Users access extensions through an official browser-based gallery, enabling drag-and-drop additions to panels or overviews for dynamic content like clocks or notifications. KDE Plasma, in contrast, treats panels as flexible widget containers positionable on any screen edge, with defaults including an application launcher, task manager, and system tray; right-click editing mode permits widget addition, alignment adjustments (left/center/right), opacity tweaks, and auto-hiding, supporting community-created plasmoids for enhanced functionality such as desktop grids or media controls.[59] Both environments emphasize user-driven customization, with Plasma's containment system allowing multiple panels—even empty ones—for tailored layouts.[60]Tablet hybrids bridge mobile and desktop paradigms by scaling touch-optimized features to larger formats, as seen in iPadOS's Stage Manager, which transforms the Home Screen into a windowed multitasking hub. Activated via settings, it displays overlapping, resizable app windows in the center, with a left sidebar listing recent apps for quick switching via taps or swipes, effectively adapting iOS-style icons and gestures to support up to four external-display windows alongside the primary view.[61] Users group apps into persistent sets for projects, dragging to rearrange or return to the Dock, promoting productivity on tablets without fully replicating desktop multi-window complexity.[62] This feature, available on compatible iPads, integrates seamlessly with the Home Screen's widget and icon grid for hybrid use cases.[61]
Historical Development
Early Computing Interfaces
The concept of a home screen in computing originated from early text-based interfaces that served as the primary point of interaction for users. In the 1970s and early 1980s, systems like MS-DOS relied on command-line prompts as the default "home," where users entered text commands to launch programs, manage files, and navigate the system, reflecting the era's emphasis on efficiency for technical users.[63] This approach evolved gradually as computing hardware advanced, paving the way for graphical alternatives that could represent the same functionality more intuitively.A pivotal shift began with the Xerox Alto in 1973, which introduced the desktop metaphor—a visual representation of a physical workspace featuring icons for files and applications, overlapping windows, and a mouse for interaction, fundamentally influencing subsequent graphical user interfaces (GUIs).[64] This innovation was commercialized in Apple's Lisa computer, released in 1983, which incorporated icons, menus, and a desktop environment to simplify file management and program launching, drawing directly from Xerox's concepts to create a more accessible interface for office professionals.[65] The following year, 1984, saw the launch of the Macintosh with System Software 1.0, which popularized these elements through its Finder application, featuring a graphical desktop, draggable icons, pull-down menus, and a trashicon for deletions, making visual navigation a standard for personal computing.[66]Microsoft's Windows 1.0, introduced in 1985, further advanced this evolution by providing a graphical shell layered over MS-DOS, incorporating tiled windows, icons, and a program manager to serve as the initial user landing point, thereby bridging command-line traditions with emerging visual paradigms.[67] These developments were driven by the need to broaden accessibility beyond expert users, as graphical interfaces reduced the cognitive load of memorizing commands and enabled intuitive interactions via metaphors familiar from everyday life, such as desktops and filing systems.[68]
Modern Mobile Evolution
In the late 1990s and early 2000s, mobile home screens began transitioning from basic text-based menus to more visual, icon-driven interfaces. Palm OS, debuting with the Pilot 1000 in 1996, featured a simple pop-up launcher accessed by tapping the screen, displaying a grid of icons for core personal information management applications such as the Address Book, Date Book, and Memo Pad on its 160x160 pixelmonochromedisplay.[69] By Palm OS 3.0 in 1998, this evolved into a full-screen Application Launcher with a 4x5 icongrid, enabling users to organize apps into categories for easier navigation via stylus input.[69] Concurrently, BlackBerry OS, starting with the 957 wireless handheld in 1999, introduced a home screen with a grid of icons for email, calendar, and messaging, navigated primarily through a trackwheel for one-handed operation, emphasizing enterprise productivity over consumer customization.[70] Nokia's Series 60 platform on Symbian OS introduced customizable home screens, with an "Active Standby" mode debuting in 2005 on devices like the 6680, displaying dynamic shortcuts, clock, and notifications on the idle screen, allowing users to rearrange menu icons and add quick-launch items for calls, messages, and profiles.[71]The launch of the iPhone in 2007 marked a pivotal shift toward touch-centric home screens, introducing a full multi-touch display that replaced physical buttons with a grid of 4x4 square icons for built-in applications like Phone, Mail, Safari, and iPod, arranged on a resizable desktop-like layout.[72] Multi-touch gestures—such as pinching to zoom, flicking to scroll, and swiping to navigate pages—enabled intuitive interaction directly on the 3.5-inch capacitive screen, while the single home button returned users to this central hub, fostering an ecosystem of synced content from iTunes and contacts.[72] This design influenced the App Store's debut on July 10, 2008, expanding the home screen to accommodate third-party app icons downloadable from a centralized store, prioritizing simplicity and visual hierarchy over deep menus.[73]Android's debut in 2008 with the T-Mobile G1 further democratized home screen innovation through its open-source nature, allowing developers to create custom launchers and proliferate widgets—resizable, glanceable app components like weather updates or music controls embedded directly on the multi-page grid layout.[13] The initial interface featured a 3x4 icon grid with a pull-down notification shade, physical navigation buttons, and support for live wallpapers, enabling diverse designs from manufacturers and users via the Google Play Store.[13]From the 2010s to 2025, advancements integrated artificial intelligence for predictive personalization and adapted to new form factors. iOS introduced Siri Suggestions in 2015 with iOS 9, using machine learning to analyze usage patterns and display context-aware app recommendations on the search screen and as dynamic widgets on the home screen dock, such as suggesting navigation apps during commutes.[74] Android followed with Google Now in 2012, evolving into app predictions by Android 11 in 2020, where AI-driven rows of suggested icons appeared at the home screen bottom based on time, location, and habits, toggleable via launcher settings.[75] Foldable devices prompted UI adaptations, with Samsung's One UI (from 2019) supporting separate home screen layouts for cover and inner displays, app continuity across unfolding states, and multi-window taskbars for the larger 7.6-inch panels on Galaxy Z Fold series.[76] Google's Pixel Fold (2023) incorporated similar features, including persistent taskbars and adaptive icon scaling for its 7.6-inch inner screen, optimizing grid density for productivity.[77] In 2024, iOS 18 enhanced home screen customization by allowing free placement of app icons and widgets, icon tinting, and larger folder views, while Android 15 introduced app pairing to combine two apps into a single home screen icon for simultaneous launch.[78][79] Augmented reality overlays emerged in widgets and quick actions, such as AR measurement tools accessible via home screen shortcuts in iOS's ARKit apps or Android's ARCore integrations, blending virtual elements like 3D previews onto the real-world view without leaving the launcher.[80]
