I just bought me a shield.
It is rooted with Nougat stock rom.
I got the shield cous I wanted to have my "own" tablet.
So I installed World of Tanks Blitz and when in sniper mode its nearly impossible to do a good aim.
When zömed in and I im going to move the crosshair a mm to hit the other tank i have to move my finger
pretty far to just get a respons. When Ido this the crosshair jumps past the target. The movment is everything but smooth.
In comparising with my ipad its horrible.
Conclusion: The screen does not folow the finger.
The problem occures when in the launcher or any other app.
Ie. When putting my finger on the screen i can move my finger about 1-2 mm with out any movement on screen.
On my old Galaxy Tab 10 there was an app for adjusting this, cous I think its a feature not a bug.
I have found one app wich I think enlightens this problem "SGS Screen" See attachement.
Minimum motion is one setting i think is the culprit.
Any one know how to adjust this or have any clu?
