Phone acting very odd.

I've had this phone all of I've week and it's possessed I believe. First of all the in different areas of the settings menu it says phone number UNKNOWN under about phone. I've got many odd services running eating my data up. Some of my settings have been changed and won't allow me to change them back. I've included some screenshots for any feedback y'all may can give. Also I'm running some sort of Qualcomm. Qti. Aurora or something and all I can find in Google is something about dual SIM card. Please help. I know this is vague but I'll answer anything I can.
