Lumia 820 --> Lumia 830 - Scrolling lag etc.

I think I have found a solution. Don't know if it will work for you but it certainly made it 95% better on my end. Make sure all apps are updated before doing this.

First, go to settings and click on date+time. Toggle automatic date+time to off and manually change the year to anything after 2148. After, try to open battery saver. It will not open and tell you to uninstall it or buy it. Press uninstall. Don't worry nothing will happen or change. Do it again. Nothing would happen again. Then change back the year to 2015 and make sure the date+time is right. DO NOT change it to automatic data+time. After, open the app Transfer my Data and agree to everything. Uninstall the app. Next open all app one by one on the start screen you have pinned. This will make sure no app is in the background trying to sync the live tile. Do that with the Games app, Music app and Video app and all others. Let it completely load (LOOK AT THE DOTS AT THE TOP IF IT IS LOADING). After, just press the power button. Press it again and go to start screen. Switch off the phone completely and switch it back on (DO NOT Soft Reset). Then enable kids corner. Power off and power on. Switch off completely and switch it on. Then give it about 30 seconds on the start screen and then start scrolling. It will be much better. Don't know if it will work for you.

Not sure if troll or serious.

I've found interesting thing, not sure if it proves anything but at least it could be a potential reason for this scroll jitter. I've looked at how WP work with touch and find out that they actually differentiate scrolling by dragging finger across the screen which they call simply DRAG, and just flicking the screen to scroll which they specify as FLICK. That's a fact so there is actual difference between dragging and flicking which some of us see. Now remember that this micro stutter looks like a content of the screen that is being scrolled sort of jumps number of times. Well Microsoft specify that when people start moving finger across the screen manipulation event called ManipulationStart occurs and than during drag ManipulationDelta event occurs number of times until movement stops, to notify system where exactly users finger is. Did you see this certain similarity there? System deals with touch by firing delta event multiple times like screen jumps multiple times, but when we just flick the screen and lift our finger from screen no delta event occurs as same as there is no jumping of content that has been scrolled. I know it could be nothing and I really don't understand how WP work and how rich works but it sounds pretty concurrent to me. Also if that's how it is, it would mean that this phenomenon is actually how system itself works and thus all windows phone devices as well. And that would mean that some of us are seeing things or others doesn't see this thing that is clearly there . Otherwise power of placebo effect . What do you thing could this be proof that this scrolling jitter affects all Lumia phones and possible source of this "issue"?
