Frantic note from a friend complaining that his phone "exploded" (and, likely expecting *me* to solve his problem -- fat chance!)
Apparently, left in car so likely saw 140-160 degree temperatures (when it's 110 outside, it's easy for car interior to *bake*).
I assume the phone is likely functional but the battery has swollen and forced the case apart. Though, depending on how difficult that was, it's also possible the screen may have been abused.
My advice: just buy a new one.
[The guy doesn't even *use* his phone (essentially) so I don't know why he's sweating this. Buy a cheap "emergency phone" if you want one for that purpose (SWMBO has one with a $5/month plan for just that purpose; an incoming call from her phone number means I've got to go "rescue" her...)]
