When entering task manager from any app and when blur control in home up is not 100% blur, the screen blinks and turns dim AFTER the animation of task manager. When entering from home screen, or the blur control is 100%, the screen doesn't blink and becomes dim BEFORE the animation, which should be the correct behavior.

2) Press and hold the Volume Up key and the Power Key.
3) When the Android logo displays, release all keys.("Installing system update" is displayed before displaying the Android system recovery menu options).
4) Press the Volume down key several times to highlight “wipe cache partition.”
5) Press the Power key to select.
6) Press the Volume down key to highlight “yes” and press the Power key to select.
