white screen on my new samsung tab 10.1 2014

Hi,

i have just bought the subject tablet in less than three weeks ago. In the first week, while trying to download apps, the screen blank out i.e. became white and after switching off and back on again, turned normal. In the process of downloading more apps and other personal stuff, white screen appeared again and have since not been able to operate normally. Every efforts to get rid of the white screen have been unfruitful. Tried to hot-boot the system but only appears normal for a few minute and the white screen will re-appear again. It's a bit disappointing as this is my first trail on Samsung tabs.

I will appreciate any help you can offer to get this resolved. I know there is a solution out there for this problem

Thanks
