Firstly, it is very inconvenient design. I use only masks for photo, because in everything else I dont want and cant figure it out. Secondly, and this is the most important. When I take photos through the application, charging on the phone drops from 40% to 0. The phone turns off. Then I put the phone on charge, it turns on and shows 5%. After 5 minutes it again shows about 40%. This always happens when I use the application.
