why is it after I installed the app, my phone suddenly turns off by itself? It happened right after I finished loading the game, and I can't do anything with the phone right now. the app's not harmful or anything right? since there's a warning thing before I downloaded the app, but I ignored it bc the guide said to allow unknown sources.
