have a note 8 and a pixel 2 xl atm and notice huge differences in overall smoothness... which is odd because my old mate 9 was pretty smooth.

it struggles to hold a smooth framerate scrolling in settings,
youtube is super stuttery

app switcher stutters ALOT too, especially in splitscreen.
Was wondering if I accidentally turned on some secret low power mode or something. Don't see any reviews mentioning this performance issue.
US version, feb security patch.
Yes even Google map when you are making a turn it is laggy which is super annoying.

Hi, curious question.
I'm wondering why the Nexus7 doesn't allow you to slow scroll/pan down at single pixel steps. Always seems to be in 2-3 pixel jumps. I got a bad habit of scrolling web pages while reading from iOS but on my N7 I get these kinda anoying start/stop jerks.
Is this related to the virtual pixel resolution being lower than the actual screen resolution? And would changing it allow one to match the virtual pixels to the screen pixels and get smoother slow speed panning?
Anyone know if some custom ROMs optimize for this?

I have been struggling with this issue for days. Looked into kernel code hoping to find anything related to scrolling or touchscreen but nowhere to find such a thing. It has nothing to do with virtual pixel resolution. If you swipe your finger at a degree of between 45-90 (accapted as scroll up by the system), Y coordinates change by 3 pixels where as X coordinates can change by 1.. Therefore its not a limitation, it is kind of scroll sensitivity which is 3px.. I've seen other devices can scroll by 1 pixel.
I believe google has set this value to 3 because of rendering issues, since its gonna render the screen 3 times more if it is set to 1. Maybe it is the optimum sensitivity. Lower than 3 pixels may disrupt buttery smoothness but its just a guess..
I hope one dev can lead us the right piece of code where it is set to 3 and we can change it ourselves to test the best..
You guys can try the problem yourself actually by installing the "Multi-touch accuracy check" app from market, which shows the exact pixel of the touch..
the xy coordinates readout from the developer "show touches" setting shows the 3pixel increments too.
when panning something just a bit faster than dead slow then suddenly gets rid of the jumps and goes smoother as well.
could it be a battery saving thing that they just get rid of taxing the cpu/gpu when people like me do these constant slow scroll pans on webpages and books etc.?

2 more thoughts:
a) this relatively coarse sensitivity can lead sometimes (not often) lead to a +/-3 pixel uncertanty in a UI element and cause it to jittter - sometimes happens when finger pressure changes.
b) I had for a while thought that it may be linked to the size of the touch sensors on the display. Being a lower cost device I figured that the HW resolution may be lower than pixel count. But I'm pretty sure that you must be always hitting multiple sensors and the system should just interpolate to a finer resolution.

When scrolled a little bit faster, it still increases by 3px , not 1.. I also assume that it is about battery saving but if I can find a way to decrease the step size, I'd love to try it by myself..
Also It can be related to the sensors , as you mentioned, but not likely.. It can catch 1px changes when swiped horizontally..
Any news on this?
As far as I can see, this is only related to touch screen; if you use a usb mouse, you can actually see the scroll by one pixel at time, and there is no graphical issues. With mouse all seems smoother...
At this point, I think It's an hardware issue of the touch screen, as the system can easly support 1px scrolling

My two cents...I tried this approach and when you move your finger with about 5 degree you can get 1 pixel change by Y and 3 pixels change by X. And if you move your finder with about 85 degree you get 1 pixel by X and 3 pixels by Y. It seems that hardware can handle the 1 pixel change by X or Y. It looks like the touch events are throttled by the system based on the distance between points.
There is no decent and satisfying answer to this yet .. I'm still waiting for a solution..
Hi!
I'm running Hyperdrive 8.1 and I've noticed that the camera drops about 10 frames when I show my camera around my closet... Whereas when i slide my camera over to my monitor, it is extremely smooth. Could it be the cluttered ness? Or...
Also there is a slight UI lag... Is there any possible way for me to fix it?
Syncs: Facebook, Google, Samsung Account, Skype, Twitter and Vine. I made sure many of them aren't synced automatically.
I think it has to do with the lighting. When theres quite a bit of light my camera is smooth but when moving to darker conditions it gets a bit choppy when moving the camera around. I.remember stock being similar so i dont think its a rom issue and it doesnt seem to affect picture quality. As for ui lag I always disable the animations and it makes the phone super snappy. The option is under developer options, near the bottom.

Thank you sir.
This is a really great tablet, and I like it very much.
But one thing is really irritating:
When in portrait mode (for me, the standard mode of operation) the scrolling is not really smooth. One side lags a bit behind the other so that a "wobbly" effect results. This is especially noticeable when scrolling fast, not so much when scrolling slowly. And it is especially noticeable when scrolling larger amounts of text.
The phenomenon doesn't occur in landscape mode.
The tablet has a very strong GPU and CPU, so this doesn't fit into the high-end-ishness of the device, and since the screen doesn't have the very highest resolution, scrolling should not pose such problems!
Does anyone know something about the reasons?
Would it be possible to eliminate the problem with a better graphics driver?
Could it be possible (on a rooted device) to "tell" Android on this device that portrait mode is the standard orientation instead of landscape, so that the wobbling at least occurs in landscape but not in portrait??
Anyone notice a difference in scrolling speed when disabling Appflash? It gets faster but doesn't feel smooth at all while scrolling in home pages
I’m wondering if anyone else has experienced this problem with certain games. Within the last couple weeks my tablet frame rate seems to have slowed down significantly while playing World of Warships. Initially gameplay will be fine but after a period of 10-15 minutes there’s a significant, noticeable decrease in FPS. I’m not sure if this is due to overheating or perhaps hardware beginning to fail. Samsung wants me to send it in for service but I thought I’d check w/ the hivemind to see if there was any tips or advice before having to do so. Here’s what I’ve already tried:
Uninstalling/reinstalling the game.
Clearing app cache.
Soft reboot.
Hard reboot.
Factory reset.
Trying w/ cover on/off.
None of these things has made any improvement. Kind of out of ideas at this point. After this starts happening it appears to impact the OS as well since touch responses and other sluggishness w/ the UI appear. Thoughts anyone?
Well out of curiosity I tried to run the game with the tablet plugged in and it doesn't seem to lag as bad. Leads me to believe it's hardware related.
More or less, I do have the same problem. I'm playing Call of Duty Mobile and the resolution is terrible and everything is pixelated. Is far away of the quality that I'm having on my S21 Ultra and is even worse than I had on my previous Tab 5e. I'm looking forward for any fixes for this problem.
i bought samsung s7 one week back, when i play pubg, resolution was too bad and frame rate drops. Tried everything not helping. So rooted my tab, installed xda's graphics driver for 865 (It is optimized for gaming), disabled game booster using service disabler. reduced framerate from 120hz to 60hz. (for pubg, i have edited user config file to play at 2k resolution). Now pubg is running very very smooth. But still i got multi touch issue when i use 4 fingers at a time. To fix that disabled all gestures, reduced full screen gesture sensitivity to low . It reduced touch issue but sometime i were getting touch problems, changed a big fire button to small and used trigger button to tap that. Now there is no touch issue at all. TAB is super smooth and no multi touch issue, u can check the game play here,(used in-built screen recoder).
