Big problem on my Galaxy Tab Pro 8.4

[Billy95Tech]

I have just bought my Samsung Galaxy Tab Pro 8.4 a month ago and it is great.

But i have a big problem and message that it keeps saying "Unfortunately, the process android.process.acore has stopped"
I keep pressing ok but it keeps on coming up like every 2 seconds and before i shut down my Galaxy Tab Pro 8.4 there was white background behind the apps on the normal Android home sceens and after i rebooted it up the white background was gone and got changed to my android wallpaper again

And i never had this problem on Galaxy Tab Pro and my old Samsung Galaxy Tab 2 7.

What does this mean? How to fix this problem? do i have to take it to a repair shop?

I would try rebooting into recovery and clearing the system cache. See if that helps.

You probably installed an unstable or busted app that is running in the background causing problems. I would reformat completely and reinstall your apps one by one.
