Hello, In iOS 10, Apple did something wrong. First of all, don't tell me its only my phone and its the app developer that needs to fix it. Its not the developer's fault. Okay, so let me tell you whats the issue. First, I have two iDevices, an iPad Air 2 and an iPhone 6S Plus, both running iOS 10.2 release and all stuff is up-to-date. I even did a reinstall before complaining. The issue is that some apps are having stuttering when you scroll or swipe or do all of this together. It is happening when you do these things while your finger is on the screen. As soon as you release, it is smooth again. Theres multiple devs having this kind of issue, like Supercell. Clash of Clans is affected too. You can reproduce it by logging in to the game, and if it wont start stuttering, go to defense log, scroll and dont release your finger! You can see the choppy and bad scrolling experience. If you release your finger, it will be smooth. Sometimes, if you double click home button and go back to game, it fixes the stuttering for a few seconds. Now you might say that its the dev fault. No it isnt. I already contacted them regarding to this issue, they told me its an iOS bug. Believe it or no. All of this issue started with iOS 10.0.0. With 9.3.5 it was perfect. The issue still persists even with iOS 10.2. Why am I thinking too that its an iOS bug? Because Siri have the stuttering when scrolling bug too, after you do the necessary steps. Open up Siri by long clicking home button. Get to the "Sorry, I couldnt get that" part. There will be a "?" mark at the left bottom place. Click on it and scroll, dont forget - do not release your finger! Do it slowly, and then try faster too, you will see the stutter no matter how you do it. IF you release your finger, you can see the difference, it will be smooth. So the game stutter - all of my iDevices after iOS 10 having it, even my classmates- all of them.
