Re: what I give permissions to Galaxy tab3 lite root?
I'm not understanding the question.
What did you do when you rooted the phone?
Or
How do you root the phone?
(The "permissions you give" when a phone is rooted are just that whatever app you allow to run as root is running as the user named root, not as its normal user name. This gives it full control of everything in the phone [which some apps legitimately need - and viruses shoudn't get].)
