Hi, can you be a bit more specific? Fake apps have nothing to do with your phone or the manufacturer.
Infact you should discern which apps may or may not be safe as alot of fake apps may have other motives and purposes on your device.
I myself tested out a few apps that worked, making supposed passive income in the background. However the payout is always minimal and takes forever and noticed it took huge chunk of battery drain 40%. Meaning I would be spending more money on electricity charging my phone than I could ever possibly make through the app plus the huge impact on my phones battery life and performance. Really not worth it. Ever!
