When iOS 10 just came out last Fall, I gave it a thorough try. Unfortunately, the app switching animation back then had some noticeable stutter issues, so I went back to iOS 9. Today I figured I'd give iOS 10 another try — first on my iphone where stuttering wasn't too bad. To my surprise, the stutter was gone. Encouraged, I proceeded updating my ipad, and was immensely relieved when I found out there was no stutter on the ipad either. Well, there may be just a tiny bit of stutter, but it's not really different from what I had in iOS 9. Anyway, I'm really happy that iOS 10 has now been fixed. Hopefully, 11 will be no worse.
