My Samsung Galaxy S21 Ultra has bad quality photos in Burst shot.Something wrong with focus or object detection.My previous models (Note 10 plus & Note 20 ultra) works perfectly in burst mode.This is an example on burst photos taken with my S21 Ultra...

When i put up (manually) my Note 9 it start incorrectly. and sometimes it does an automatic restart and incorrectly again.

my Samsung s9 plus shows "learning usage patterns" in device maintenance, no estimated battery life is shown.any information to solve this problem???
