Anyway reviews on the china stable miui 8 for 64gb (8.0.2). So far pretty snappy, but batt drain is a bit more compared to miui china stable 7.5 (7.5.6).
I also notice that the ram usage is higher compared to the older miui, higher by around 200 to 300mb.
I had call answered but cannot be heard issue at the start, i off the volte options and it appears to be gone (i off it on the older miui also, since not supported yet by local telco).
Camera performs better then miui 7.5, but still lack the "punch" to it. But it's ok for me, since i not a photographer type of person.
Sound wise, ok for me. Did not try the sound profile as i still prefer normal non-enhance sound. Volume is ok for me, pretty loud. I'm using the piston 3 earphone.
As for notifications delay, i don't experience any.
I think that's all for the review. Overall, the miui 8 china stable rom is pretty good IMHO. I will be trying out the china beta when my vsl is complete.
