: Advanced kernel tuning within updated ROMs can help preserve the

For those already running a custom ROM, the update process is typically more streamlined than the initial installation. While a "clean flash" (wiping all data) is often recommended for major version jumps (e.g., Android 12 to 13), many developers support "dirty flashing."

The Heavy Hitter: LineageOS 21 (Android 14QPR3)

The most stable and widely used ROM right now is LineageOS 21, maintained by Linux4.

• The Vibe: Pure Pixel. No bloat, no Samsung cloud nagging, just AOSP.
• Performance: The 60Hz panel finally feels fluid. UI stutters present in One UI are gone thanks to a lighter RAM footprint.
• Battery: With the stock kernel, users report 4.5 to 5.5 hours of SOT on original batteries. With a new battery, you can push 6 hours.
• Working: Everything. Bluetooth LDAC, VoLTE (in supported regions), Wi-Fi calling, and even Samsung’s LED View Cover.

Stock camera hal is broken on some AOSP ROMs. | | SafetyNet / Play Integrity fails | Install "Play Integrity Fix" module in Magisk. Clear Google Play Services data. | | S-Pen disconnects | For AOSP ROMs, install "Spyke" from the Play Store. It emulates Samsung’s Bluetooth S-Pen framework. | | Wi-Fi / Bluetooth MAC address changes | This is normal on custom ROMs. It does not affect functionality. | | Vendor mismatch error on boot | Update your TWRP to the latest version. Old TWRP cannot read new ROM scripts. |
