Default [Q] Some camera problems

Hey, first i use stock m8. And i find some issues on my m8.
-When i get into manual mode, if i set the shutter speed is 0,8, its ok. But when i try to upper 1, screen looks white completely and camera will buggy. And when i try to other capture modes, it still stucks. So i have to close and open again my camera app.
