I've managed to get something on my Moto G5 (android 7) which mucks around with power management in the background when I open the phone from standby. Apart from also popping up adverts for other (useless) apps, it turns off bluetooth and wifi when it thinks the battery is a bit low, which can be a PITA.
Can anyone recommend an app to help me find what is doing this, so that I can uninstall it?. The couple of startup managers which I have looked at seem to be useless.
As a supplementary, are there benefits from rooting Android devices or is it risky? My IT experience goes back a long way, but I'm not really up to date with modern stuff.
I run Ccleaner and Malwarebytes (on W10 as well) but have never dug very far into Android.
