⚠️ Do not expose a device with 4.14.117 to untrusted networks or app environments without additional mitigations (seccomp, SELinux enforcing, hardened userspace).
In summary, Linux Kernel 4.14.117 represents the "middle age" of Android kernel development—a period defined by refining the relationship between the Linux source code and the unique demands of mobile hardware. If you want to dive deeper into optimizing your device: (to check for kernel updates) Custom ROM interests (like LineageOS or Pixel Experience) Performance goals (battery life vs. gaming speed)
| Manufacturer | Device Model | Android Version (at kernel release) | |--------------|--------------|--------------------------------------| | Samsung | Galaxy A50, A20e, M30s | Android 9 Pie / Android 10 | | Xiaomi | Redmi Note 8, Mi A3 | Android 9 Pie | | Nokia | Nokia 4.2, Nokia 3.2 | Android 9 Pie | | Motorola | Moto G7 Play, Moto E6 | Android 9 Pie | | Google Pixel | Pixel 3a / 3a XL (early updates) | Android 10 | | OnePlus | OnePlus Nord N100 | Android 10 |
The Linux kernel follows a versioning scheme: major.minor.patch . For example: kernel version 4.14.117 android
When upstream stable maintainers released point update 4.14.117, it delivered dozens of backported bug fixes directly to the Android open-source ecosystem. This specific point release was widely integrated into vendor trees by chipset manufacturers like Qualcomm and MediaTek, acting as the foundation for stock firmware and custom kernels alike. Key Technical Improvements in Kernel 4.14.117
Ultimately, kernel 4.14.117 stands as a testament to the success of long-term Linux maintenance, proving how micro-updates keep our daily hardware safe, stable, and efficient years after its initial release.
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. ⚠️ Do not expose a device with 4
Kernel 4.14 was designated as an LTS release, meaning it received extended support and backported security fixes far beyond standard versions. In the world of Android, Google often selects specific LTS branches to serve as "Android Common Kernels." Version 4.14 became a staple for devices launching with Android 9 (Pie) and Android 10, providing a mature foundation for Qualcomm, MediaTek, and Exynos chipsets.
| Area | Observation | |------|-------------| | | Stable with minor OOM improvements over .110. | | Scheduler (CFS) | No major regressions; EAS (Energy-Aware Scheduling) functional on arm64. | | Storage (F2FS) | Fixed a data corruption bug affecting encrypted F2FS partitions. | | Power management | Suspend/resume cycle improved for QCOM platforms. | | Known bug | Rare sdcardfs deadlock when unmounting (Android-specific). |
The kernel is the bridge between your phone's hardware and its software. Version 4.14 was a pivotal release for Android because: Long-Term Stability: gaming speed) | Manufacturer | Device Model |
Understanding Kernel Version 4.14.117 in the Android Ecosystem
For developers in the custom ROM community (such as LineageOS or Pixel Experience), kernel 4.14.117 serves as a common upstream baseline. Upstream Merging
Thus, 4.14.117 represents a specific snapshot in time (circa mid-2019) of the 4.14 LTS branch, adapted for Android’s unique requirements: binder IPC, ashmem, low memory killer (LMK), wakelocks, and vendor hooks.
In the digital world of 2020, while users were busy obsessed with flashy new dark mode and gesture navigation, Kernel 4.14.117 was the one actually doing the heavy lifting. It wasn’t a "feature" you could see; it was the bridge between the cold, hard silicon of the processor and the vibrant apps on the screen.
