I am a samsung m30 user.I was having no issue in my device but after updating the latest security patch,i got a bug in my device.My camera is not working.When i click on the camera its just go crazy.The screen becomes black and the phone gets hanged for a while.I have tried clearing the cache and clear data option but still it is not working.I have also reset my device(means formating).But still the problem is not solved.Plz fix this bug as soon as possible.
