Can someone explain what is happening why phone is not booting samsung A20? The voltages are all normal when I press power key 0.8v, 2v, 1.1v, 1.3v etc as soon as I release the powerkey the voltages disappear. On charger they fluctuate on and off and I get no power to the battery terminal. The flow chat to diagnose said to check (U7034) which should be 1.8v and I am getting nothing. Can anyone help?
