Tombstone said: Hey Shteev, sorry to hear that you're experiencing this issue. Though, this issue sounds to be more of an issue with the app priority on your device rather than with the game itself. Please keep in mind that when you switch between the application on your device, or leave an application in sleep mode (including answering a phone call), the priority of your device is divided among all open programs. This divide of priority on your device might cause the game to shut down due to the enhanced required usage rate during matches. If your device is unable to handle having multiple tasks open at the same time, I'd recommend to avoid putting the application into the background settings during the middle of a match. Hope this helps!
