Samsung S8 Rear Camera Blurry - FIXED!
Hi guys and girls,
Same problem here, most of the times I open the camera app, i was blurred and I had to strongly hit the screen with my finger to be able to take any pictures.
Solution: You need to reset the Camera app cache and stored data, from both normal Android and from the Safe Mode Android.
Normal Android:
1) Go to Settings -> Apps -> Camera App
2) Click on FORCE STOP button to close the app.
3) Click on Storage and here click on Clear Cache and then on Clear Data
4) Do not open the camera yet, click on the Power Button and power off your phone.
5) With the phone powered off, click on the power button to turn it on and then, when the first logo appear, the one with Samsung Galaxy S8(+), click and hold the Volume Down button until it enters the Android OS Safe Mode (that's roughly 30 seconds). To be sure you did the right thing and the phone is indeed in the Safa Mode, on the left bottom corner it will appear a text saying Safe Mode which will remain on the screen no matter what.
6) Repeat stepps 1) to 3).
7) Power off you phone again and now power it on standard, only by pressing the power button.
8) Problem should be fixed, you can now open your Camera and set again the quality of the pictures and everything else.
