So I just got the bluboo S8 and INSTANTLY the incallui stopped working, I looked everywhere online but everyone always said stuff like clear the cache and disable the Google app and none of that works, I've tried a reset, I've tried downloading a different calling app, it's just not working! Im not to technical so explain in baby words please what to do, device is up to date to. (I should also say my messages aren't appearing when I send them though I fixed it by using a different app)
