4 stars: So far I like this app, I chose it because it looked like it had a better variety of different monitors and checked the phone for problems and information than other apps, I've not been disappointed in the app, it's good.
5 stars: Nice Would love if you add a test for microphone when speaker is on like when do a phone call with speakers are on some times the other person could not hear you. so that test will help discover if the microphone related to speakers have something wrong
3 stars: I have HTC U ultra. And I had fingerscanner problem. Well sometimes it works and sometimes not. I tried many apps.

This app I guess is not helpful as mentioned before :(
