Hacked iPhone?
My mother has 2 iphones—6+ and 6s+. The 6+ was mine, gave it to her because I have a new one. Now, the 6+ isn’t logged in to an apple ID while the 6s+ is logged in using my mother’s apple ID. 2 days ago both phone suddenly won’t open because it says the passcode is incorrect. Tried fixing it…input the password several times, take a rest, tried again until the 6s+ opened. Unfortunately, the other didn’t. Yesterday, when I decided to try again, it says that someone used “Find My Phone” using an apple ID I don’t know. The phone got reset. Is there anyway I can help recover the phone? Thanks in advance.
