Understanding kernel 4.14.117 requires looking at what changed in this specific micro-update, how Google integrated it into Android, and why it remains relevant for legacy device support and custom ROM development. The Role of Kernel 4.14 in Android History
Implementing logic like Schedutil or Blu_Sched for smarter task handling.
Fixes to use-after-free (UAF) bugs within the binder IPC (Inter-Process Communication) mechanism—the core communication highway of the Android OS.
The primary reason point releases like 4.14.117 exist is security. Hardware manufacturers and ROM developers backport these specific sub-versions to protect users from emerging exploits. kernel version 4.14.117 android
Devices running 4.14.117 as of mid-2019 were considered secure for their time. However, any device still on this exact patch level today is dangerously out of date unless the OEM or custom ROM developer has manually backported later patches—a practice known as "backporting."
As of 2026, the industry has largely shifted towards 6.1 or newer LTS kernels, which provide four years of support, whereas 4.14 has already reached end-of-life (EOL) for official Google support.
Thus, for a device used primarily for calls, messaging, light gaming, and media consumption, 4.14.117 offers a smooth, lag-free experience. However, newer apps expecting kernel 4.19+ features (like io_uring or newer GPU APIs) may crash or underperform. Understanding kernel 4
What (if any) are you currently facing during the build process?
While the 4.14 LTS series reached its end-of-life (EOL) in early 2024, many legacy Android devices still operate on this version . Key Features & Changes in 4.14.x
Version 4.14 was one of the primary kernels used during the rollout of Project Treble The primary reason point releases like 4
While upgrading to 4.14.117 brought vast security improvements, custom developers often faced issues with closed-source camera or Wi-Fi binaries. If a vendor built their driver strictly for kernel 4.14.80, upgrading the base to 4.14.117 could occasionally break functionality, requiring community developers to write custom wrapper patches. How to Check Your Device's Kernel Version
The 4.14.117 confirms the kernel base. The extra string ( -g12345678 ) indicates a specific vendor build hash.
Kernel version 4.14.117 is a specific point in the long and impactful history of the 4.14 LTS kernel series within Android. It serves as the foundational software layer for numerous popular smartphones released around 2019-2020, including key devices from Google, OnePlus, and Realme. Understanding this kernel provides insight into the Android Open Source Project's development process, the use of LTS kernels as a stable base, and the technical complexities involved in securing and maintaining older devices in the modern Android landscape.
Within Android, 4.14 LTS was used extensively for devices launched around 2018–2020.
The 4.14 kernel branch offered a long lifespan compared to non-LTS kernels, allowing for sustained support and security updates, which is crucial for Android devices' lifespan.
