[Q] Your device isn't compatible with this version topic

I just got my first samsung note 10.1 GT-N8000

i encountered this problem when i was trying to download some apps from the play store. for example, i was trying to download instagram, snapseed, and other photo editing apps, but there were always a notification saying that my device isnt compatible with this version.

is there any problem with my device or is it just the apps is not compatible?
i also got the "device not registered" notification when i try to call.

any help?

thanks in advance
