Its been about 3 weeks since I purchased my S6 edge (G925i), but it has always been showing this persistent lag when scrolling on almost any scrolling-based applications such as the Play Store (the worst), Instagram, Maps and even the Settings menu. I have re-installed the firmware via Smart Switch, cleared cache, basically everything that could be done in hopes of eradicating this issue. Does it happen with everyone else as well? Ive done the *#0*# touhscreen test and it didnt display any problems there. Do you think this could be a software issue? I've played with my mum's G4 and it was buttery-smooth when I was scrolling on it. Hell, it was even able to display some cool animations that came with the 5.6.8 Play Store update when I tap an app, while my S6 edge doesn't perform like that.
EDIT 1: Youtube link of lag on settings menu - https://www.youtube.com/watch?v=SE4VW8fNmB4
EDIT 2: I have uploaded 2 more videos displaying the lag, as mentioned by pratz82 its really odd how reviewers don't pick this up, especially when they go to the Play Store to download apps.

You´re not alone. It bugs me that all the reviews never mentioned it. I´m starting to think Samsung is paying the reviewers big bucks....
Root, custom rom and greenify shouldn´t be needed on a 2015 flagship device to make it usable.
My Galaxy S4 and Nexus 4 are more fluid than this.... (though admittedley both rooted with custom roms) Still doesn´t justify them being on par or more fluid than a 3 year newer flagship phone..
Mine does it too. It's not just the browser, it's anything that requires scrolling. Out of the box I would also get:
- Stuttering in scrolling across the map (all apps)
- Pressing app drawer every so often it doesn't animate, stutters and apps just pop up
- Device is locked, I unlock and go to home screen to be blank while elements randomly and slowly show up on screen
Few more odd, less-than "project butter" smooth. This is my first non Nexus device since the Galaxy SII so I don't know how other phones are.
Mine doesnt do this. Are you using a custom rom? If you're using stock, which firmware version is it?
I am not necessarily an expert, but here are some things i would personally try in order to figure out the cause:
1. If youre rooted, try changing the cpu governor to "performance". use a free app called "kernel aduitor" (not a typo) and you'll find the option to switch it from interactive to performance in the sidebar menu under CPU. If it resolves, it may mean your issue is related to your kernel's cpu management.
2. make sure you do not have power saving mode enabled. This mode imposes limits on various components of the phone to save power at the cost of performance.
3. Download a process monitor from the play store and confirm that no processes are using large amounts of cpu, Alternatively you can utilize the built in process monitor of your phone by going into settings>about device, and repeatedly tapping "build number" until a notification appears confirming that you have enabled developer options. Now go back to Settings>developer options (towards the bottom of the list)>Show CPU Usage. This will let you see the processes that are using the most cpu and how much of it theyre using.
4. If you have enabled developer options using the procedure above, navigate to them and enable "force gpu rendering" and see if that helps at all.
5. Make sure your cpu/battery temperatures are not unusually high. A good app for this is AIDA64. you can find temperature stats under the "Thermal" section. Typical battery temperatures are somewhere between 30 - 40 while the phone is not charging. CPU temps above 60 may indicate that something is causing your phone to work too hard. Eventually the phone will begin to enforce limits on the cpu in attempt to lower the temps, resulting in less-than-optimal performance.
6. Check how much free memory you have under the application manager. If you are rooted, you can try downloading terminal emulator and entering
Code:
su -c "sync; echo 3 > /proc/sys/vm/drop_caches"
to regain a good deal of memory if your available memory is low.
7. If you are using a custom rom, make sure it doesnt disable scrolling cache. Maybe ask the developer if you are unsure.
always on performance gov can not be the solution..you will always power your CPU to max
Out of the box the Galaxy S6 lags and stutters while scrolling and it is very apparent. If someone has a device that does not, that is a defect because this is normal behavior of this device. I'm not basing this off of my personal phone only...between a few of my friends and family, the models in the stores, they all do it. This is something iOS has down correctly.
My playstore is terrible, when it comes to scrolling and selecting animations. However, I had two other units that didn't suffer from this.
No idea why...
I highly doubt that this is a hardware defect of some sort, if not this is a serious issue that needs to be raised to Samsung, looking at the number of people that are also affected by this. Maybe this only applies to G925I units with Cat 6 data speeds? But heres just my two cents on this. Perhaps maybe due to the closed source nature of the Exynos processor, developers were unable to properly optimise their applications for the device, which is why on some, if not on most occasions, Qualcomm devices perform more smoothly, since kernel sources are consistently released for most variants of the SnapDragon processors. Even my S4 performs better in Google apps such as the Play Store and Google Maps. I really want to avoid rooting my S6 edge, just for this once, so I hope the fix won't involve the need to dig into the system to solve this issue. Im still running 5.0.2, I heard 5.1.1 was not a major difference, but I'm just hoping for the best. We deserve better from our devices running the supposedly "fastest" Exynos CPU that Samsung is so proud of. One thing that still boggles me though, is how even Samsung made apps are lagging, especially the Settings menu, and theres also a split second lag when on the recents carousell.
Same here. Started after 5.1.1 update. Thinking about selling the phone, $%@! Samsung. Will miss the camera though.

I've been using GBX0* + 3.4.26.13 kernel for sometime on my uk rhod100. I know that it's not recommended for rhod100 but I have found it to work very well (a big thanks to the developers - hopefully the bug with bluetooth causing occasional reboots will be solved soon). After some reading around and experimentation I have found a setup that I am very happy with. Below I share my current setup in the hope that some find it useful. I stress that none of this is original and can be found scattered around the forums.
Initial Installation
Firstly, when installing the ROM I remove all the apks from the system/app directory that I have no use for. The apps I have removed without any detrimental effects are:
Bluetooth (I belive this is only required for file transfers via bluetooth which has never worked with any xdandroid build on my device)
GenieWidget (News and weather widget I never use but does cause device wakeups and launches when a data connection is found even if not used)
HTMLviewer
LatinimeTutorial
Mediauploader
PinyinIME (chinese android keyboard input)
Protips
Talk (Gtalk - never used this)
Vpnservices
I also uninstall launcher2 once I have installed an alternative after flashing (Lightning launcher with the least demanding settings and no wallpaper, as few widgets as possible and one screen is recommened)
Performance
The [[Speed Improvements]] Brainstorming & Testing Thread!! is full of useful tips and advice however was started sometime ago. I did use the V6 supercharger script for some time with good results however I now use and application called Android Tuner from the play store. With this app I can do many of the tips and tweak from the convenience of an app. I use it to do the following
1. Contolling the CPU frequency for overclocking. Stable upto 710MHz on my device
2. Controlling OOM settings (I use 8,16,32,64,96,128)
3. Controlling startup apps
4. Turning off the receivers for GoogleServicesframework
5. Performing tasks like FixPermissions / Clearing System caches / Wipe Davlik etc.
The app does a whole load more (changing SD cache / changing SysCtl settings/allowing uninstalling of system apps) - if people have other setup tips please share
I have also recently started using an app called Seeder (available for free to xda members) which seems to improve general performance. I am in the early stages of trying this but it does seem to help a bit. The reviews generally seem positive but the manner in which it works is debated. Any other experiences of this app would be appreciated. One drawback is claimed to be a decreased batter life - I have not seen this.
Battery Life
All the usual stuff re screen brightness and timeout apply here as well as data connections etc.
I have been using an app called One Power Guard which does seem to improve battery life mainly during standby without any discernible decrease in performance. This app causes various system and kernel tweaks,
Disabling data connections etc is well known to help improve battery life but I have also found a big difference by turing off Use Wireless networks in the Location and Security Settings.
A second battery with this ROM is recommended and I am very happy with the Mugen 1800mah battery.
Essential Apps
Notification Toggle by j4velin I would say is a must. It allows shortcuts (for apps and settings) and toggles (like CM7.2) for system settings to be placed in the notification area. With the rhod100 not reconnecting the wifi networks after a screen off having a rapid toggle function is essential. Highly recommended and light weight,
Leo AGPS injector app by tytung is essential for speeding up GPS locks. From reading around when using this app first extablish a data connection, then turn on GPS and then run the widget. Definitely speeds up GPS lock times. (Use GPS test to check)
Clock Sync by sergey baranov is another essential for preventing clock drift. Also I have read that an accurate clock time can improve GPS lock times so another reason for this app. As in the xdandroid FAQ I have it set to sync every hour. It may also be beneficial to change the NTP server to a local one.
That concludes my round up of my current setup. Please contribute any other tips that I have missed out. The above have only been tried with this ROM and work well on my Rhod100, I hope this is of help to someone.
Thanks akk29, very useful. I have now tried some of the things you have, some I will get around too as I play more and find more out (eg, controlling startup apps, uninstall inglauncher, GoogleServicesframewor). I'm constantly turning my backlight up/down - is there a fix for doing this automatically?
The jury is out as whether I'll switch back to WinMo... I love all the new apps I've got that WinMo just doesn't have.
The biggest problem, (at least I think it's what's causing problems), is speed (I'm running ok at 787 MHz at the moment!). The phone doesn't want to know about the Facebook App - it says it's loading it, but then bombs out after thinking for quite a while. Also it's very fussy about touching the screen. Trying to type using the screen keyboard is almost impossible. I love the hardware keyboard (which is why I've got the TP2), but sometimes I just need a quick soft-key entry. And whether I pressed a button or not, only time would tell.
But I'll use it and play with it for a little while longer, and most probably become too reliant on all the android apps to revert back!
[I had a WinMo tweak for boosting the volume which made my phone very loud, but now it seems quite quiet, especially playing songs]

That's a old kernel/rom. Try the newer release like the 3.4.41 kernel.
Autobrightness was fixed in 3.4.26.
WizardKnight, I am using 3.4.35 Kernel - I've got a RHOD100, so the 41 didn't work very well (which is a shame, as fps has increased in that build). Thanks for the note about the autobrightness (looking at the changelog I have it working now I turn off/on the LCD).
Anyone had better luck with the Facebook app / integration?
I wanted to know what is the default behavior of android as of L/M (and if anything will change come N) when the device if put on sleep/suspend/power button is pressed. I'm not developing apps (but technical enough to know stuffs just not updated), so not posting over the developer section so hopefully someone here knows.
My problem is all apps I'm using gets suspended when I press the power button even those that I don't expect to get suspended and will do wakelocks gets suspended on my Asus Zenfone2. Which is weird since a few months back it does not behave this way (I'm suspecting aggressive battery management on the manufacturer's end). So I'm thinking of changing phones or flashing roms, but before that I want to know if this is something that is going to be the default going forward or is something the manufacturers think I will be happy to have (which I don't and I can't see any option to disable it).
Specific example that is easy to check, Fluid. It's a torrent app. I'll press the power off on my phone (after I check that the download is picking up) and I would expect it to continually download (since I configured it and allowed it to do so afaik). But when I come back to check, it would say 0kbps. But if I keep my screen on (set screen off or sleep to never) I see the download rate being constant.
Note that 1.) it does not kill the app unlike some other manufacturers (Sammy, Oppo), it just behaves like it's suspended. So it may or may not be Asus, just wanted to be sure and set my expectations going forward with android. And 2.) I have already check all settings I can get my hands on. On both the app and the system. Phone is unrooted for now. Data is not limited, power is set to performance. the only thing unchecked is stay awake while charging.
Thanks.
I did a few more google searches using different terms and I think I found my answer.

It seems like when android realize that you are no longer actively using your phone, it goes into a state where it will not allow any apps to work. with exceptions but still limited background processing. Well, as the poster on the link said, welcome to the war on background processing. I'll just keep the screen on so it does not go into doze mode or find a legacy phone to use...
For those who care, apparently having any Accessibility Services enabled (Settings->Accessibility) can cause sever performance issues. After looking into it I'm not the first to have this issue and it doesn't seem like Google will be fixing anything. I've have reproduced the issue on stock 6.0.1, Android N Preview 4, and Pure Nexus.
I was having issues in Chrome on certain websites where the page would lock up for several seconds and would generally perform terribly. After doing some research I traced it back to Accessibility Services. I disabled my services (Greenify, Nova Launcher) and restarted and the issue was gone. Not only that but all websites and the entire Android system now runs more smoothly. Having either of the services enabled brings the issue back so it's likely not specifically an app issue. In my case the services probably shouldn't have been enabled anyway but the feature shouldn't cause a drastic performance decrease.
In my case, the worst website was http://slickdeals.net/?modern_opt_out=1?no_mobile=true (desktop site, classic mode) where clicking any link resulted in a 10 second hang. It was slow even when blocking adds with AdAway. Other sites are affected as well but I don't recall specifically which ones.
I don't know if it's just the 6p or Android 6.0+ with issues or if there's more to it than I've discovered but my phone runs much better now and I figured I'm likely not the only one using any Accessibility Services so it may be worth looking into if you are.
I have accessibility on and that website works well without lags. However what you are reporting is true, I heard that Chrome does lag because of that in certain websites. It shouldn't affect performance in the system though. I haven't noticed any difference by disabling the option. I need accessibility for Keepass.

Hello all, i've tried to find the asnwer through the google using different keywords but i'm unable to find any answer at all.
I have a samsung galaxy note ii, i suspect either it's cpu or gpu is broken. Mostly in web browser, the device sometimes display graphical glitches on some object areas, similiar to corrupted jpeg image data. Those glitches are also present in the screenshots i take.
Also, after i use some mildly gpu intensive apps even for a short while(2-3 min), apps start to behave weirdly. Like, whatsapp crashes while i'm typing, some functions stop working, etc. In extreme cases, all processes crash one by one, displaying error messages if i want to kill the process. And of course they launch again and they crash again.
I'm currently using the device on half clock speed(800MHz), this way at least the device is somehow stable.
It seems i can't underclock the gpu on this device, so i'm looking for a way to completely disable gpu acceleration on apps and see if the gpu is really the culript. If it is, i'll continue to use the device that way.
I'm not sure about these devices architecture so i'm not sure if completely disabling the gpu is reasonable, maybe gpu is also responsible for generating the display output.
So, does anyone know if there is a tweak or application that can force cpu graphics/rendering system wide, or a better idea to try?
Did you find a solution? Also have the same problem, and did not find a way to dosable HW acceleration yet
I use the tablet mostly for playing. And I am used to move between them without issues. Unless I open a bunch of other apps or browser with multiple tabs and what not. The games remain running without issues or at least they used to. Normally I don't update anything, except for the games because they are live service and I can't play them if I don't. After learning that this update would improved multitasking I updated.
Ever since I can't keep the games open if I leave them for like 20 minutes or maybe less, haven't time it.
Using it as I did, closed them. So I decide to clear all and only play one. After a notification, went to that game for daily tap immediately went back to the prev game and it had close, which cost me a match. After finishing what I was doing on that game. I went to the settings to see if something was amiss. And all the apps I remember disabling that I couldn't uninstall like Youtube are still disabled. I don't have any social media app like FB or anything that would be constantly running. And went back to the game. Lo and behold had to restart again. I checked Dev options and Apps "Background process limit" still standard. Memory is at 4~4.5 with so much free I don't get I it's been so aggressive. Have 66 apps on "deep sleeping" have things like digital well being and other monitoring stuff also off. And the only thing I changed was enabling the "Labs" to allow Multi window for all apps. And just now, went to homescreen while I picked something from the kitchen, I know I didn't take more than 5 min because the screen didn't even timed out. And when I tap on a game, had to relaunch.
God this is ridiculously annoying. And non of the games updated since. I only updated a couple of apps from store.
And worst, I updated believing it would be better at multitasking. Like it would be smarter when using split screen, but it isn't. Maybe it does improve for Samsung apps. But I've seen nothing good from anything I use. And changes to the UI could've been implemented better. Like having dual pane only when you are holding the tablet lanscape. I remember having very old android device that had dual pane but revert to single if you hold them portrait.
I'm considering doing a full reset. But I'm hoping not too. Between the apps and games, which most are 5GB+ up to nearly 10GB it would take me a very long time to set everything again, Easily a full day for some games. (Very bad old, first gen copper line DSL)
Is anyone have any type of similar issues. Cause it would suck if I reset it and that's just how it works now. And it wants me to use the "keep open" feature. Which I don't like, I do like to use the clear all.
One of the main reason I got this particular tablet was for the multitasking. This is the first device I didn't try rooting out of the bat because of a warranty and what not and decided to give it a go as is. Now I'm not sure If I'm just spoiled by years for rooted and heavily modified devices. Or this is just a Samsung thing.
@Omizuke: Not sure if this is related to RAM management, but I'm also on September update. When I update apps via Play Store/Galaxy Store, the device will completely freeze for as long as 30 seconds. It just locks up, I can't do anything. Can't pull down the status bar, nav buttons don't work. Then suddenly it returns to normal. I get the same thing when connecting to WiFi or pairing via Bluetooth. ROM is clean flashed with Odin, i also did a factory reset.
This didn't happen at all on the July update.
I'm not seeing any issues with app killing, as you've described it. All opened apps continue running and I can return to them on demand. I play a lot of games, COD Mobile in particular, and I switch apps a lot between rounds.
I feel you on the not wanting to set up everything again. I save cached copies (APKs/obbs) of my games/apps on my SD card, so I can set everything up without Internet. Just use an app like Total Commander/X-plore to copy the apps.
