Hi all, Yesterday I downloaded the latest update and after that my Samsung Galaxy A71 kept shutting off whenI didn´t use the phone. It would only keep it working if I was playing music or another app. After a few hours it got worse and it didn´t work at all.  Now  (a day later) when I charge it, it continuously starting up but when the Samsung Galaxy A71 screen pops up, it shuts down again (black screen) after 3 seconds. This happens too when I reboot it with the powerbutton and volume down button (10seconds).  What is going on and how can I fix it?    Thank you ... View more
