It also debuted QHD (1440p@30fps) video recording capability on its front-facing 3.7-megapixel camera, surpassing standard for sharper self-recorded content and video chats.

Known Issues

Hardware Failures

One of the most prominent hardware failures in the Samsung Galaxy Note 4 involved the embedded (eMMC) storage chip, particularly in models equipped with the 805 processor. Users frequently encountered the "mmc0 read failed" error, accompanied by symptoms such as sudden freezes during operation, random reboots, and persistent boot loops that prevented the device from starting properly. These malfunctions typically emerged after 1-2 years of regular use, leading to complete inoperability as the eMMC chip, responsible for storing the operating system and user data, degraded prematurely. The only reliable resolution required replacing the entire , often costing hundreds of dollars out of . Battery swelling and overheating issues were also documented in genuine Galaxy Note 4 units, often intensified by prolonged heavy usage or exposure to high temperatures during charging. This degradation could cause the device to generate excessive heat, potentially leading to physical bulging of the battery casing and reduced performance over time. Samsung's official guidance highlights that such swelling results from gas buildup in aging batteries, advising immediate discontinuation of use to prevent risks like fire hazards. These problems primarily affected devices from 2014 to 2016, though they were less widespread than eMMC failures. The fingerprint sensor in the Galaxy Note 4 was unreliable due to its swipe-style design, which was sensitive to swipe speed, angle, and finger moisture, leading to frequent false rejections and prompting many users to revert to PIN or pattern locks.

Recalls and Lawsuits

In , the U.S. Consumer Product Safety Commission (CPSC) issued a recall for approximately 10,200 refurbished Galaxy Note 4 smartphones distributed by as replacement devices between December 2016 and April 2017. These units contained 3,500 mAh lithium-ion batteries installed by during refurbishment, which could overheat and pose fire and burn hazards to consumers. No incidents were reported, but and urged affected users to stop using the devices immediately and provided free replacement batteries along with prepaid shipping labels for returns. A lawsuit, Beture et al. v. America, Inc., was filed in August 2017 in the U.S. District Court for the District of on behalf of U.S. purchasers of Snapdragon-powered Galaxy Note 4 models. The suit alleged that knew of but concealed a defect in the embedded (eMMC) storage chips, which caused premature failures, random reboots, freezing, and the "mmc_read failed" error, ultimately rendering devices inoperable after the one-year period. Plaintiffs claimed violations of the Magnuson-Moss Warranty Act and various state consumer protection statutes, seeking damages for repair costs, lost data, and diminished device value. denied the defect allegations, asserting that the eMMC issues fell outside coverage and were not systemic. The case proceeded through discovery and motions, with Samsung maintaining that any failures were due to normal wear or external factors. In 2020, the court approved a settlement that provided monetary compensation to eligible class members who submitted valid claims by the deadline, resolving the dispute without admission of liability by Samsung. No broader device-wide recall was conducted for the Galaxy Note 4, though the eMMC issues prompted Samsung to offer goodwill repairs or extended support in select regions for affected users beyond standard warranty terms. These events incurred substantial costs for Samsung in legal fees, settlements, and customer service initiatives.

Legacy and Successors

Innovations and Impact

The Samsung Galaxy Note 4 marked a significant milestone in the Galaxy Note series by being the last model to include a user-removable and microSD for expandable , features that were omitted starting with the Note 5 in 2015 due to a shift toward sealed designs for water resistance and thinner profiles. Although the Note 8 in 2017 reintroduced microSD support up to 256 GB, it retained a non-removable , ending the of easily swappable power sources in the lineup. This design choice in the Note 4 enhanced user repairability and flexibility, allowing for replacements without specialized tools and storage expansion beyond the base 32 GB internal capacity. The device also brought innovative health-focused sensors to mainstream smartphones, including a integrated into the rear camera module—building on the Galaxy S5's implementation—and an (UV) ray sensor, the first of its kind in a smartphone. These sensors worked with the S Health app to measure blood (SpO2) and UV exposure levels, providing users with real-time alerts for sun protection and wellness tracking, thereby popularizing biometric and in flagship phablets. The Note 4's refined advanced phablet multitasking capabilities, enabling precise , pressure-sensitive drawing with 2,048 levels of sensitivity, and features like screen-off memos and air command gestures for quick app access. Introduced as part of the Galaxy Note series that pioneered the category in 2011, the 's enhancements in the Note 4 influenced broader adoption across the industry, including Apple's introduction of the for iPads in 2015 and integrated support in subsequent Android tablets and foldables. As of 2025, the Galaxy Note 4 holds collectible appeal among modders and enthusiasts, with active custom ROM development—such as unofficial /e/OS-R builds based on —extending its usability for basic tasks like browsing and media playback despite official support ending years ago. Its resale value remains low, with trade-in offers averaging around $6 and maximums up to $15, though it is valued for repairability thanks to the accessible design highlighted in detailed teardown guides. Culturally, the Note 4 powered early experiences through the Gear VR headset, serving as the first optimized for immersive 360-degree demos in partnerships with , which helped propel mobile adoption. This contributed to achieving a global of approximately 25% in 2014, bolstering its position amid growing competition.

Successor Models

The Samsung Galaxy Note 5 served as the direct successor to the Galaxy Note 4, announced on August 13, 2015, and released in the United States on August 21, 2015. It featured a 5.7-inch Quad HD Super AMOLED display, a non-removable 3,000 mAh battery—marking a departure from the Note 4's removable design—an Exynos 7420 Octa processor, and 4 GB of RAM. However, Samsung skipped its release in Europe during 2015, opting instead to focus on markets like the US and Asia, with the device not becoming widely available there until later or in select regions. The Galaxy Note series continued with the Note 7, announced on August 2, 2016, and released on August 19, 2016, which introduced a curved-edge and an iris scanner for biometric authentication. This model was recalled globally in September 2016 due to battery defects causing overheating and explosions, leading Samsung to discontinue it entirely. In response to the Note 7 issues, Samsung released the Galaxy Note Fan Edition (FE) in July 2017 as a safer alternative based on Note 7 hardware, which reintroduced expandable storage via microSD card support up to 256 GB. The primary successor, the Galaxy Note 8, was announced on August 23, 2017, and released on September 15, 2017, featuring enhanced capabilities such as improved pressure sensitivity and new gesture controls for tasks like screen capture and . Subsequent models in the series built on this foundation by adopting curved displays as standard and integrating iris scanners for secure unlocking, evolving the phablet's design toward premium aesthetics and advanced biometrics. The Note series continued through the Note 9 (2018), Note 10 (2019), and Note 20 (2020), introducing features like wireless charging, connectivity, and advanced camera systems. However, following the Note 20, Samsung discontinued the dedicated Note lineup in 2021, integrating S Pen stylus support into its flagship Galaxy S Ultra models starting with the Galaxy S21 Ultra, thereby merging the Note's productivity-focused legacy into the broader S series.
