im running JB 4.1.1, not rooted, running in performances mode, I have constantly lag issues, this is my current Display setup:
In the end i noticed that i was getting less lag on higher settings:
Draw distance 100%
Screen Resolution 100%
Visual Effects High
Dynamic Shadows On
Frame Limiter: On
It seems that the more i tried to lower all settings at once or individually, the more lag i was getting or using default settings. Im sure this is not an issue with the Prime hardware.
Anyone has any suggestions?

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..
Hey guys
In my old phone the galaxy ace there was something known as render effect which would change the visual color of the screen.
Is possible to get it in the S3?
I basically need the night mode. I use my phone a lot in the night with zero secondary light hence the screen is too bright even on minimum brightness.
I tried screen filter app... But beyond certain limit you can't read anything on the screen
The night mode + screen filter was my settings during the night to reduce brightness on my old phone.
How can I get it on the S3?
"Render Effect Galaxy Ace" brings up no worthwhile results, so I have no idea what specific effect you're on about, but the app Galactic Night has some effects. If you're running the Siyah Kernel or Perseus, they also support custom mDNIE profiles, so if you have a lot of time...
I just want something that will lower my screen brightness
Similar to screen filter app
With Lux you can lower the screen brightness below the stock minimum (automatically our manually) .

Works great.
During night time it is very useful it can decrease your brightness to EXTREME LOW.
Hi all, I just upgraded from the Sony Xperia Z4 Tablet to the Samsung Galaxy S6 Tab. All in all it is a wonderful tablet but it also shows that the Xperia still remains very good in 2020 despite its age!
That said, I noticed a loss of resolution on some apps with the Galaxy.
Now I know that these two tablets have the same resolution (2560x1600) but a different screen size. As the Galaxy screen is larger, its ppi is smaller (287 ppi vs. 299 for the Sony). But I have the feeling that some applications behave on the Galaxy as if they were on a phone.
The Catan application for example has a tablet controls behavior on Xperia, as well as a very fine and pleasant resolution, where the same app on Samsung has a ridiculous resolution and phone controls (I put the app on my phone to compare and the controls are the same). See screenshots.
Now, I tried to play with the minimum width in the developer settings, which affected the menus, but it doesn't work in games.
Do you know how to solve this problem or if there is a trick to make the applications "believe" that they launch on a tablet and not on a phone?
You can try these options:
1 - In the Game Booster settings see if resolution is not 100%
2 - In the Display settings set Screen zoom to minimum
3 - In Developer options try to increase the Minimum width
When I am playing a certain game (Dragalia Lost), I often notice performance issues when there are significant amounts of particles on screen. However, going into YouTube, starting a video, and allowing it to enter PIP mode and returning to Dragalia seems to alleviate a significant amount of stutter, returning it to a full 60-fps framerate. What does PIP force the phone to do that allows it to run smoother? Does it force the game to render things through a different means?
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).
