Since the last update all my apps have random brief stutters, it makes any fast moving games impossible to play. My wife has exactly the same model of tablet and hers is doing exactly the same thing since the update.
The brief pauses last about half a second and if it's a game everything will then jump forward.. feels like it's the whole device pausing. Happens once every minute or two.
I have gone through multiple conversations with Samsung support and jumped through all the 'clear cache, clear data, check malware, reset etc..etc..' with their final solution to the problem being uninstall all your apps......which would leave us with expensive paper weights.
If anyone has any ideas it would be greatly appreciated.
