Sounds like you had a virus or spyware on you phone. Personally what ever phone you get I wouldn't let it autoload your old apps. You want an app download it only from Googles app store. And I would suggest a good antivirus for your phone. That will hopefully catch stuff like this
No Issues...
I don't think this has to do with the cell providers. I had 2 updates last week for play and mine says Nov1st still. I'm on Verizon. This is rather amusing at this point.
I don't remember having that issue. I do know that sometimes it likes to show a different speed . It will show me doing 65 great then I look over it it says I'm doing 86 mph. :p I keep hoping I'll get an update that will fix it.
