Happened to me too. Disabling hw overlay just help but doesn't fix the problem. I still have flickering if i scroll down while the video is playing. Maybe is an option in chrome and youtube?
nope, network speed only available on QS
1. U need to provide info/log of "a11 flashing"
The rom you are flashing is for nokia 6.1 plus(drg_sprout)..you have to download the one for juice..next time when flashing rom make sure you download the correct rom for your phone to avoid hard brick
