Second, . The greatest curse of Android fragmentation is not the version of the OS (Android 10, 11, 12) but the kernel version and its accompanying board support package (BSP) from silicon vendors like Qualcomm, MediaTek, and Samsung. A kernel like 4.14.117 is tied to a specific generation of chipsets (e.g., Snapdragon 845 or 855). Once a vendor stops updating its BSP for that chipset, it becomes prohibitively expensive for phone manufacturers to continue kernel updates. This is why many "perfectly good" phones stop receiving security updates after two or three years—not because the hardware is dead, but because the kernel and its proprietary drivers have reached end-of-life. The jump from 4.14 to 4.19 or 5.4 is not just a number change; it often requires rewriting hardware abstraction layers (HALs) and retesting every driver.
Kernel version 4.14.117 in Android represents a foundational, security-focused, and stable version of the Linux kernel. It enabled a generation of Android devices to function securely, with robust security patches and improved performance. While the industry has moved to newer kernel versions, 4.14.117 remains a crucial part of Android’s history in creating secure, reliable mobile computing.
Released on , the .117 sublevel brought essential stability and security patches to the 4.14 series. Notable broad features inherited from the 4.14 branch include:
Attempting to run very modern apps or customized software on older 4.14 kernels can sometimes cause compilation issues, necessitating updates to the kernel source code.
This update included fixes for the F2FS (Flash-Friendly File System) and EXT4 filesystems. These patches prevented data corruption during unexpected device shutdowns and improved sequential write speeds on UFS storage chips. kernel version 4.14.117 android
The Linux kernel 4.14 is "vanilla" (general Linux), but the 4.14.117 used in Android is a developed by Google and tweaked by OEMs (Original Equipment Manufacturers) like Xiaomi as discussed in Reddit threads (1.2.1) . These modifications include:
Low RAM allocation routines were refined. The update fixed edge-case bugs where the Android Low Memory Killer (LMK) daemon would prematurely close background apps, leading to poor multitasking experiences for users. Impact on Custom ROMs and Android Modding
The 4.14 kernel was a milestone because it was the first LTS kernel to receive an extended support window of six years (originally two). For Android, this longevity is vital. It allowed manufacturers to ship devices with a stable foundation that could receive security patches long after the initial launch, directly addressing the "fragmentation" issue that plagued earlier Android versions.

, meaning it no longer receives official security updates from the upstream Linux maintainers. Linux Plumbers Conference 2026 Key Features and Improvements Second,
This release integrates various fixes for the Linux networking stack, protecting Android users from remote code execution or denial-of-service (DoS) attacks when connected to malicious Wi-Fi networks.
You will frequently find this kernel in Xiaomi, Pocophone (e.g., Poco M3 [surya]), and various Samsung devices running Android 10 or 11, especially those with Snapdragon 662 or 700-series processors. 2. Key Features and Improvements
For the technically curious, here is a snapshot of the impact that the Android common kernel version 4.14 had in just its first few months of development, compared to a mainline Linux kernel:
: This version is heavily associated with major releases like the Samsung Galaxy S10 series, Pixel 4 , and the ASUS ZenFone 6 . Once a vendor stops updating its BSP for
After January 2024, upstream Linux no longer provides public fixes for 4.14. Android vendors may still supply private patches.
When we speak of , we are referring to the 117th patched iteration of the Linux 4.14 kernel, customized and optimized by Google and SoC vendors (like Qualcomm, MediaTek, Samsung Exynos) for use within the Android Open Source Project (AOSP).
Before diving into the specifics of 4.14.117, it’s essential to understand what the numbers mean.
