I was using my Tab S3 yesterday morning and the screen froze and then it turned off. Even though it had been charging overnight and was showing almost full battery, it will not turn on.
Since then, I've tried charging it and carrying out a hard reset (holding down various combinations of buttons: power; power+vol up; power+vol down; power+home) but it's still dead. I bought it new in Sept 2019, so it's barely 18 months old and shouldn't be a battery health issue.
Thank you in advance!
