My phone seems to do what it wants, it shows commercials, it flashes, it decreases it's own volume and it does all of this without me touching. If anyone has had this trouble, I would like to know how they fixed it. I though I had a virus and did a virus cleaning and it still goes on. Also, I could get on to the network at work as of yesterday, 12/10/18 but as of last night, I can't. Should I do a factory reset? I really don't want to lose all of my stuff, I have a lot. Can someone please help me?
