How do I get a hacker out of my phone? The other day my phone number was added to my Google account, data was turned on and off. Different things have been happening. I have a LG V35 and it has an LG VPN section and when I check the log. It shows background scripts or whatever being run in my phone. I do not have a VPN. I tried resetting my phone to factory and it didn't work. Please someone help me get this person out of my phone. The other day it said it got one profile.
Look through your installed app (in settings). Is there some new weird app you have never seen before and not installed yourself which is labeled as "System-App"? Yes? Your are screwed. Only way to get rid of it is to re-flash the whole ROM. Well you could also root your phone and use one of countless apps/modules to remove System-Apps. But God knows what the virus will do when it gets root access. 
I have seen this years ago on a Huawei Mate 1. The app was turning on WiFi and Data permanently to load ads and malware. Factory reset did nothing. Clean flash of a new ROM was the only way.
