In my experience the previous build was better. This one has a lot of slowdowns when opening the notification bar or the multitasking, the previous one was much faster and smoother, it was nearly as fast as my S6 with Nougat, even if it had some flickering (on the new build there are much less graphical glitches). Also it has some issues with touch sensitivity, it's kinda hard to pull down the notifications , the auto brightness is still not working and the camera app has only 4:3 resolutions
