i agree with you. Stock rom still best stable. I try stock rom and kernel mod. BEST battery, best performance, with all function.I tried almost all Android 9.0 and 10 Roms, they dragon the battery cery fast. Nothing cant help. Best is stock ROM.
Many mod rom stupid. The basic functions are completely unstable, malfunctioning, eg: gps, bluetooth, sim unstable,...
Tips: rom stock 6.0.1 + kernel MOD is BEST!
