I have a Samsung Galaxy tab A SM-355Y. About 4 months prior it started to get hot when charging and using. Then one day whilst charging it got VERY hot and never turned on again.
Today l received a brand new battery for it, l then put it in (very difficult to open case), but following a YouTube video l managed to replace the old one.
About 1.5 hours into charging it up, l felt the back of the unit, and, as you’ve probably guessed, hot in the lower third section. So, it wasn’t the battery at fault!. So then l let it cool down, and then switched it on again (to try and isolate exactly where the heat was radiating from). The location turned out to be -, if you can imagine dividing the back into six sections - one line down the centre (top to bottom), and two equal lines side to side - now if you measured 2cm up from where the USB cord goes in and drew a line around a small soup spoon (between the two lowest sections of the case), that is where the heat emanates from. Now, having given that location, l have to tell you about a very strange abnormality, right bang smack in the centre of that ‘spoon’ shape, is something l that can only think of to describe as a ‘pimple like’ bump, (raised from the inside of machine, the bump being proud on the outside of the case) - l can give an exact location, - 4 cm up from USB port, in the dead centre. Possibly, what ever is causing the problem is behind that, and the raised ‘pimple’ has been caused by the heat of a faulty component directly behind there!
Can anybody shed some light on this, particularly what is directly behind the ‘soup spoon’ and the ‘pimple’ areas?
