About the new official update for S4 I9500XXUFNB3 I have 2 questions
1-If I have a rooted device with JB 4.3 and I flashed it , what happens ? the root access will be denied ? I think yes
and is there any root way ?
2- and this is the most important , I read that ART is not supported yet in this version , so should I wait it to be supported or it will not be available ?
