Security setup

[Izak Huntz]

I have a friend who has the metro fierce 4 now. However on 3occasions since 2010 my friend has been a victim of spyware. Over the years we have tried everything we can think of or research. There has never been any signs like hot batteries, unusual pop ups, the data usage I'm not sure about. What's the best way to see if the new phone has already been attacked and what's the best way to stop it
