Help with finding a place to fix phone. Grey pouch in back of phone swelled up and separated back of phone. Phone still works but case is compromised. Please help!:frowning_face_with_open_mouth:
Probably your phones battery. Make sure you are charging it and shutting it off when guided to do so. But make sure it's off and in a safe location until a technician can help you either at a phone repair shop or a Samsung dealer
sounds like a phone battery. Do not use the phone anymore. turn it off and seek out a phone repair shop near you. Battery "bloating" is extremely dangerous.
