First of all, you should check whether your cell phone is rooted, because you can no longer trust a rooted device – even if you have done the root yourself for good reason at some point. On rooted devices, attackers can hide a spy tool so well that you cannot discover it in a few simple steps.
Therefore search your device under “Spy Apps” for tools that are traditionally used for rooting. These include SuperSu, BusyBox or KingRoot. You can also use the RootChecker app to check directly whether your mobile phone is rooted.
