Hi all, yesterday I charged my S3 and woke up this morning and noticed that it was off and when I turned it didn't came on. When I plugged it for charging the lower bottom of the phone heated up very fast and right now is very hot, I tried to charge it with the original battery and heated up very fast and charged from nothing to just a 3% and replaced it with a replacement battery that I bought and had and the same happened the lower bottom of the S3 heated up a lot or I would say too much but its charging normally and still very very hot...what could it be???
