Yeah. The improvement is nothing to sneeze at. I was pretty frustrated with redraws, lags, stutters and force closes. Apps are running properly in the background now regardless of how many I have open and they are not redrawing.
Call me a happy customer.
I cannot wait for 5.1 then on my Necus 6 as I am disheartened by refreshes when my Moto X 2014 is fine.
Can one get an apk file to update to 5.1? I do not root or do android sdk, I would not even know where to begin.
