Problems with MK90.0 with the Mi Note Pro



Hello again
I’ve noticed some annoying bugs since I jumped from the MK81 to MK90 for a few days and a few versions (btw why did 81 disappear from the site? ). Mainly:
The camera doesn’t record video
YouTube doesn’t work well with quality above 720p60- and most of the time even this stutters
The CPU doesn’t downclock when the screen is on- It stays about 1555MHz all the time, however the 4 BIG cores work well and disable themselves when not needed.
This is especially weird since the MK81 worked perfectly fine in all those aspects ( I don’t know much about the development of ROMs so it might not mean anything)
Thanks in advance !
