Can not add custom ringtone (tried putting .mp3 file in /internal/Ringtones and the add ringtone menu remains empty even after restart +++ using Zedge and other ringtone setting apps failed too);
Music player apps wont show music from any source (internal or Sd card). Music files also dont show in the Audio folder in Google Files.
Battery percentage jumping with 3-4% sometimes;
The volume slider, located on the right is too tiny;
Speaker's volume at lowest is too loud;
Slower battery charging;*
Slower startup and SIM card initialisation;*
