I have left my phone in the bathroom while taking a shower. Will the moisture from the heat cause water damage? Ever since my phone has been glitching such as, going black (screen will turn black but the phone isn't fully turned off), freeze, go to the homescreen when I'm browsing apps. This has been happening for a couple of months. Went to some phone repair shops and they just said it was the battery? Is this false or true? Thanks.
