[Q] Lagging Issue topic

So I'm just on the basic stock rom rooted on the sprint version. I've noticed every 30 sec when im doing something on it, it will freeze and then respond 3 seconds later, as well as songs on blue tooth lag as well. Any suggestions. Oh and my ok google available everywhere is greyed out and im on English and i believe svoice is enabled. My favorites wont display on the edge bar either when i add them and press done.

[ help lagging] sm-t211 topic

Hello xda-dev users.
I have Galaxy Tab 3 SM-T211 rooted, currently with sweet dreams rom.
Every time i start an game the game does not play well, it is laging.
Like Minion Rush (Despicable me ) is not even playable with the lag.

I clean the tablet with Clean Master.

Do i have to change the rom with better and not so heavy? Ho i can fix this.

Thanks in advance.
