I have a Samsung 12.2 inch tablet SM-P900. When not in use I keep my tablets standing vertically in a bookshelf.
The other day I noticed the screen of the tablet had separated from the tablet. After disassembly it turns out the (large) battery seems to have been encased in a soft plastic bag instead of the normal hard plastic case. The bags (there seems to be two) have swollen to the extent that they have forced the display to pop away from the rest of the tablet.
The tablet is composed the three layers, the display, the electronics, and a back cover. The back cover remained attached to the electronics.
Videos showing how to replace the battery for this tablet show what appears to be a completely different battery.
As I remember, I bought the tablet very soon after it was initially offered by Samsung.
Does any of this sound familiar to you?
Thanks for any suggestions.
