I have an Rn2 with 32gb
It has the MIUI 7 by 5.10.16 beta
Is it the last one?
If no, Why is imposible to actualize it?
For someone like me, with a few knowledge it is beber a stable ONE or a beta?
it depends on what tipe of use do you do with your phone... for example with stable you have great battery life and almost no bug, with beta you have all the weeks new features but maybe with some bugs...
