I tried gluing it back with a pretty strong adhesive, but it didn't stick (adhesive was pretty old though) and it only made the soft plastic harder. The next phone I'm getting will ideally have wireless charging so I don't have to open that USB flap so often and it would also be nice if it were waterproof, I'm hoping the next Nexus will be waterproof.
Did anyone drop a Xperia S in water and still manage to save it?
Oh and true the in-call volume is so low, I have to ask people to say things again (looks really unprofessional when looking for a job, luckily I still managed to get one
) and you can forget about calling from a busy street (I use my headphones in that case). It's too bad you can't test this when buying a new phone, and review sites seem to ignore call quality nowadays..
