Help please!

[AC Question]

Help please! My phone started opening apps unexpectedly and dialing numbers on its own. I try to access the phone but its like it has a mind of its own.i downloaded CM security, scanned for viruses but nothing came up. I've also tried factory rest and now the phone is stuck in the select language section, when i press the screen it doesn't respond. What do i do please? My phone is a huawei p8 lite. thanks
