@TaRsY, have you changed the power plan setting from smart to performance? Things definitely seemed more peppy for me once I switched power plans, and the performance plan does not seem to use a whole lot more battery. You might also try changing the resolution with the ROG power saving, which I remember reading in a different thread seemed to also improve response time.
Power plan setting is set to performance (by the whay that's the default value).
The primary reason I bought this tablet was the sreen resolution for nice reading experience. No way I'm going to give up this.
I have a OnePlus3, which is a quite fast phone with 7.0, but I'm currently using AOSIP, a well-majntained CAF rom, which provides smoothness I've never seen before. These two devices maybe shouldn't be compared, but my sis got a Honor 8, which feels also smoother than the Mediapad (that has already beta emui 5.0)
The mediapad looks like having struggles when it's under heavy io load.
There's definately room for improvement in the near future.
