I have a Samsung S7 Edge and recently I've noticed that I've had to empty my cache at least once a day. When I do it clears about 1gb. The problem is that before my cache is emptied, I've noticed that my notifications/messages/alarms dont make a sound, and YouTube videos dont play and i get an error message. Also facebook videos dont play or load. But once i empty the cache, everything works fine again for a few hours until it happens again. Any ideas on whats going on and how to fix it?
