Hi I have a Samsung Galaxy tab 4 , 10.1. a few days ago I pickup my device and it was normally. But after about 1 minutes it shows me an error message about storage space and then the screen go black while the notification area was shown. Then I try to restart the device by pressing the power button for 10 seconds or more. After restarting, the device works normally for 1 or more minutes and the cycle repeated. Please help me to fix it
