I have a Samsung Galaxy Grand Prime and it just glitched out. Never done this before. My phone said my dad was calling, it came up as it would usually with his name and number. But he wasn't calling; he was right next to me not even using his phone. I tried answering or rejecting the call, but it wouldn't work. It just kept saying "incoming call" until I turned my phone on and off again. Is this just a phone glitch or was I hacked?
