I totally agree with this opinion. I also did factory reset, delete cache, etc.. But nothing's better.
It is stuttering when multi-tasking, app switching (recent apps), even app opening.
We can see the frame rate is dropping, and these are really annoying me.
I think the basic of pure android is smooth UX and fluid animation.
Please, we want Nokia upgrade these things soon.
Yup dropped frames and stutters. Janky UI smoothness. Hardware is more than powerful enough this is not acceptable.
