For any production or consumer-facing Android product, migrating to a newer LTS kernel (5.10 or 5.15) is strongly advised.
Includes refined patches for hardware-level vulnerabilities like Spectre and Meltdown, minimizing performance overhead while maintaining data isolation.

Based on field data from devices running 4.14.117:
Understanding kernel version 4.14.117 for Android requires looking at its security enhancements, architectural optimizations, performance impacts, and its enduring role in the custom ROM development community. The Role of LTS 4.14 in the Android Ecosystem 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 However, any device still on this exact patch level today is dangerously out of date unless the OEM or custom ROM developer has manually backported later patches—a practice known as "backporting."
While major smartphone manufacturers have moved on to newer kernel generations, kernel 4.14.117 remains highly relevant in the aftermarket development community (e.g., XDA Developers).
The 4.14 series of the Linux kernel was designated a version. LTS kernels are specifically maintained for an extended period, ranging from 2 to 6 years, receiving critical security patches and bug fixes over a long lifecycle. These LTS releases form the bedrock of the Android Common Kernels (ACKs).
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: The Role of LTS 4
Mobile devices constantly transition between cellular data and Wi-Fi networks. Kernel 4.14.117 introduced specific patches to the networking subsystem, addressing memory leaks in the socket handling layer and resolving edge-case packet drops. For Android users, this translated directly to fewer random Wi-Fi disconnections and more stable tethering performance. 2. File System Refinements (f2fs and ext4)
Linux kernel version is an older Long Term Support (LTS) version commonly found in Android 10 devices. While the 4.14 series officially reached End of Life (EOL) in January 2024 , Google provides extended maintenance for specific Android common kernels. 📱 Device Compatibility
