Adjusting CPU and GPU frequencies to maximize gaming performance or extend battery runtime.
It included fixes for Wi-Fi, Bluetooth, and audio drivers, ensuring that the interaction between the Android OS and hardware components remained stable.
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 kernel version 4.14.117 android
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.
Android devices heavily utilize F2FS (Flash-Friendly File System) for user data partitions due to its superior read/write speeds on NAND flash memory. Kernel 4.14.117 includes vital bug fixes for F2FS, addressing long-term degradation issues, garbage collection inefficiencies, and potential data corruption during sudden power loss. It also includes mature optimization for ext4, which is often used for system partitions. 4. Control Groups (cgroups) v2
The kernel is the "bridge" between your phone's hardware (like the screen and processor) and its software 0.5.7 . Version is a Long Term Support (LTS) branch, meaning it receives security patches and stability updates for years rather than months 0.5.5 . Do you need assistance on a device running this kernel
Version 4.14.117 was part of a regular update cycle to address vulnerabilities identified in Android Security Bulletins Android common kernels | Android Open Source Project
Are you compiling a or building a custom ROM ?
Independent developers frequently fork the stock 4.14.117 vendor kernels to build custom variants (e.g., ElementalX, FrancoKernel). Using 4.14.117 as a stable, bug-free base, developers can safely inject modifications such as: While upgrading to 4
Updates to EXT4 and F2FS (Flash-Friendly File System) improved data integrity and read/write speeds, which directly impacts how fast an Android app opens.
Developers frequently "upstream" older stock kernels to version 4.14.117 (or higher) to inject the latest security patches into devices that manufacturers have abandoned. Conversely, if a device originally shipped with kernel 4.14.80, a custom kernel developer will merge the changes from 4.14.117 to improve overall system security and responsiveness. Popular Modifications Enabled by 4.14.117
LineageOS 20 (Android 13) for some old devices has rebased kernels to 4.14.250+ or even mainlined to 4.19. For instance, the (SD845) originally shipped with 4.14.117 but now has community builds on 4.14.336.
