What can cause the screen / digitizer to bulge out on the left side of the screen? My first guess is the battery but the back is normal and intact. Can it just be heated, as if removing it, and pressed back into place?
@never20ld don’t do anything other than checking the battery for now. A bloating battery will always push the screen out before it would deform the back. Samsung Galaxy S7 Battery Replacement Do not heat it up until you check the battery. Recipe for disaster……
