New to the neighborhood and with a new app

Hey guys, I just finished the entire production cycle of my first app, this is the link on Google Play:

https://play.google.com/store/apps/details?id=flashlamp.robotcountry.net&hl=en

The app is a simple flashlight that works with the LED flash or screen. Please Test it and let me
know about the problems that are going on, so I can fix them and then have a
wide range of compatible devices.

I am happy to belong to this community.

Thank you!
