Meizu m2

Since i installed xposed framework with FlashFire i can’t find some apps in play store like PokemonGo or Snapchat. Is it because of xposed or something else?

When i press volume rockers they control only media volume not ringer volume so its very annoying that i must go in settings to lower the sound and when you lower it it starts ringing, its easier to just do beep beep on home screen like on Samsung or any other phone.
