best fix is to throw lg devices away and buy a quality product if not clearly its a hardware / heat sync / pressure / thermal compound/ cooling related issue like most electronics made 2018 and above. Designed to work just long enough to get past that warranty state. To tackle issues like these us real techs / iPhone techs (excluding iphonetechguy ) we. Can use heat guns , heat wave ovens with successful results . Sad part is its never a perm fix without properly reseating the pins aka reballing which is to big a job for suuch cheap devices. See how they got every angle covered the big corps. Sad hustler world we live in.
