My note got 1 problem. When I open contact and tap on 's' to find name start with 's', it stop at name stating with 'm'. No matter how I tap on other character such as 'v', 'x', 'p', it only stop at 'm'. I had to scroll down to look for the person name I want to contact.
Anyone have this problem?

Am using it. What do u mean by lag? I'm still satisfied with swiftkey in my Note 7

Just do the testing but can't notice the delay. Maybe my typing skill slow.
