I just noticed an error on my MI3W. If I record a video, no matter how long and recording finished, and returned to home screen a few minutes later the phone is freezing. Screen is not responding, button under the screen is glowing when I tap it. After reboot everything is working fine. If I use a third party camera app (lgCamera) every thing is fine. If I switch back to system 2 with a stable version with 4.3 android (JXDCNBD14.0) the camera is working fine.
