Note 4 lag?  That article is true biase.

I don't have all mention issue. Note 4 is crazy fast compare with all previous release phone by Samsung.

I also owner of HTC ONE M8,  I know how all those phone work.

All instant open in Note 4 and even 99% open faster than my friend iPhone 6 plus.

The only delay 1 to 2 seconds is the recent apps. That the only part got problem in entire note 4.

Android smartphones may lag a bit.....but still much more exciting than dull, overrated iPhone.

I literally yawned when I borrowed my friend's iPhone 5S
