I would still blame iOS for all the stutter while scrolling. Apple engineers changed smooth scrolling code and hence most apps started stuttering. The developers are lazy to fix something which was working perfectly few months back. It is not their fault.
Has anyone read iPad Pro review of
Anandtech?
In the review it is clearly mentioned about stutter on a device which is as powerful as iPad Pro. So this thing is also being noticed in mainstream media.
We do not need bulls*** reason that "blah blah blah iOS is getting more complex" Stutter is real. The fact that it is spoiling the touted "Apple Experience" should be enough for Tim Cook to discipline his erring or complacent staff.
