[Q] Do you think that Project Butter in JB will make the phone feel more snappy?

A problem I always had with the Xperia S is that the whole thing feels extremely choppy and clunky. I have extremely low tolerance for choppyness, and this phone has always felt really clunky for me, it's hard to pretend the choppyness isn't there. There is nothing that makes me feel good about a device than silky smoothness, and even though the phone is still very fast and reactive, the slow framerate and microstutters are extremely noticeable, especially if you ever used a smooth device before (such as my good old Xperia Ray on gingerbread which was smooth like an iPhone, and when I upgraded it to ICS I couldn't stand it anymore because it became horrendously stuttery).
I was wondering, since Project Butter promises fully accelerated UI and elimination of the persistent lag that all android phones have, do you think this will finally resolve the slugginess of this phone's stock rom?
Is PB an OS features that all phones running JB have, or do the developers (in this case Sony's) have to implement it on their own?
Also, regarding the current stock ICS, there is nothing that helped with the constant lag and choppyness in the UI, the only thing that DOES make a difference is enabling "force GPU rendering", it's found under "developer options" and disabled by default. Once you enable it, scrolling lists (such as the settings menu) will become silky smooth (you have to go back to home and then back to settings menu to notice the difference). With this disabled, scrolling every list menu is embarassingly choppy. It doesn't cause any battery drain so I recommend everyone to enable it if you haven't already.
I seriously hope JB will resolve the constant choppyness of this phone's UI.

If you're really curious you could flash the test version DoomlorD posted. There's also this video on Youtube:
http://www.youtube.com/watch?v=kNLODO3YOnA
Looks like it is more fluent, as was expected, but ofcourse that's a nearly empty firmware. Some 3rd party apps can make your phone a lot slower, even when they're supposedly not running. A clean installation of ICS is also quite fluent compared to the lags I've had caused by some apps before I removed or restricted them.

I can't flash it because I'm not unlocking my BL. Also, which apps do you think are the most resource hungry? I already disabled facebook and all social network related stuff, most services like sony select, etc. No difference at all.

My Xperia S and my Nexus 4 feel as smooth as each other using go launcher and obviously one has project butter and one doesn't

A simple solution would be to set a background process limit to 3 or less (developer options-resets on reboot so take care of that)
Also decrease the transition and animation from 1 to .5(dev options again)
If u are rooted(which am expecting u are)
Use romtoolbox or any utility capable of profiling ur cpu...set two profiles..screen off->governer-ondemand-low frequency(will save battery)
And one as screen on->governer-performance-max frequency(reduce ur lag)
If u have too many apps..use greenify or some app with same functionality
These basic settings have kept my ion lagfree all the while

Hit a thanks when someone helps

for what it's worth, i just came to the xperia S from the original galaxy S. i was running JB on that, which has nowhere near the specs of the xperia S, and JB was smooth as silk there, so it does seem to make a noticeable difference. moreso on 4.2 than 4.1, however.
unfortunately i've been hit with the bootloader unlock = no , so the wait for jb again begins..

That's why I posted the link to the Youtube video so you could get a glimpse that way .
I'd also disable Google+ and Google Talk if you're not using those. And some apps that you installed yourself from the Play Store can make your phone sluggish as well. I used Greenify to force my games and some apps to hibernate (Angry Birds, Dropbox, Google Drive etc), saved over 100mb in available memory. That has made my phone a lot less laggy. I usually don't encourage using app killers but Greenify is doing a good job with no errors for the past 3 days.

absolutely yes
jb leaked is the smoothest thing i have ever seen

So laggy..please help.

Hi guys, I just got the tab 3 8.0, and I like most part of it but the performance is seriously bad..I have already restored all my apps from Google server. While running apps and switching between them, I can't take all the lags it has. I just got it today so I can return it if I want but I'm wondering if rooting this device actually gains much performance improvements. I used to have a galaxy s2x, which has a similar if not worse spec than this tablet, and I don't know if It was because I running rooted version of touchwiz or not but the performance was pretty good. This tablet is much worse. A simple reboot fixes the lag but after a few hours, as I use it, I notice the stutters while using it. I just had a serious lag in Google plus app, it was stuttering so bad, but it came back to smooth after 5 seconds.
So will installing the custom Rom available for tab 3 8.0 improve the performance significantly? I know there are not many ROMs for tab 3 8.0, so any user of this device just rooted the tab and tweak it themselves to gain performance improvements? Not just little bit, but a lot.
Thanks!

One thread is enough, you don't have to post the same question in multiple sections.
As I said on your other thread, stop blaming the device and look at your apps. My 8.0 isn't laggy at all. In fact it's pretty zippy. Chances are one of your apps is causing the issue or you have too much stuff filling your memory. Do a factory reset. If the lag stays gone add your apps back a couple at a time till you find the one that's not playing nice. How much free space/memory do you have left? The fact that the lag goes away when you reboot points to it being an app problem.

go to developers options and turn off all animations,
also disable CPU power saving option in power saving mode,
then check if you feel any difference

Thanks for replies guys!
So I believe it was ram issue. Too little ram left when it was stuttering really bad. However, I'm wondering why this device was not releasing ram by closing open apps for the forgoing app to run well. This is the android way of managing ram isn't it? But when I checked the ram manager in the task manager app that came with the tab, there was very little ram left, less than 100mb I believe.
After I have been using it for more now, I also rooted it, and I deleted almost all the unnecessary bloatware. I think I see a huge improvement in performance after I did this, deleting bloatware.
The tablet runs pretty well now.
Although..I still see some stutters in animations, where the animation has dropped frame rates. Is this just due to Touchwiz? It doesn't happen every time, but sometime when opening app, or switching between apps in recent apps panel. The animations sometimes are pretty choppy. It is not a huge deal, but I just remember that my S2X was much smoother. Maybe it's because I was running a custom rom which was heavily tweaked by deviant development.
Any info would be great!
Thanks for your help again guys.

Hmmm, i have no problem at all, the tab 3 runs pretty smooth, stock. Now I have set the animations to 0.5 in developer options and it runs even smoother. Ok, it's not as fast as the Note 2, but it runs very nice. Very happy with it. (Using Nova launcher)
(I also disabled some if the apps that come with it, SNS Samsung Facebook, Samsung widgets, flipboard an the lot)

I see. Mine is running pretty nice right now but I'm feel kind of afraid as I use it thinking "will this animation be choppy?" As I long press the home button or something. Lol I really don't like choppiness.
So you don't notice ANY choppiness in animation? I want to know if it's only my device so that I can figure out what's the cause. I'm using nova launcher as well btw.
Thanks!

Tab S 10.5 lag

I've had the Tab S 10.5 for about a month now and the lag while using everyday apps is driving me crazy. My top three offenders are:
1. Chrome
2. Play Newsstand
3. Play Store
I've done the following to help improve things:
- Changed launcher to Nova.
- Disabled bloatware (everything I can without rooting).
- Installed Chrome Samsung support library.
3D heavy games seem to run fine. My last tablet was a HP touchpad running CM11 so I am used to dealing with a few quirks. I stepped up to the Tab S to get away from some of that though. I know Android is infamous for scroll stutter, but it seems to me that a flagship tablet should easily beat out a bootleg touchpad.
Is this on par? Also, does anyone else's tab s get really hot around the touch screen near the Samsung logo? Maybe the Nexus 9 is worth another look. :silly:
Thanks for your comments.
Edit: I've read similar posts on lag. It seems like the argument boils down to: 1. Personal perception or 2. A mysterious "bad batch" of hardware.

i did the same steps,my tab is full of apps and games but i have 0 lag and the browsing is also fcking smooth. In the settings i also turned of features like dual window.
Are you sure you turned off fully power saving mode? About heating,if i play a game like gta or hearthstone i can also feel a warm area under samsung logo but is not hot and pretty common if you play games.
edith and use chrome beta instead of the standard chrome

Chrome lags on the tab s. Happens to most people. To fix over heating i installed a custom kernel that would optimise and prevent heating. Some big games do lag aswell.

I am already using chrome beta. The stock broswer is smoother.

can you upload a video to see the lag we are talking about?
I want to buy this tablet, and Ive read many posts about lag... but actually, is it very annoying? is there any video to see it?

Only on certain apps. Chrome and a few others. On some games it just lags on loading screen but not during gameplay. Watch a veiw reviews on youtube. Theres some videos talking about the lag. Touchwiz launcher also has lag but can be fixed.

I think it depends on your perception of lag and what apps you mainly use. In my case, Chrome and Newsstand are always up so I see the lag constantly. I wish I had a Nexus 9 side by side for comparison. If I get a chance I'll take a video, but it might be hard to see. I played with a demo model at Best Buy and it seemed faster than mine as well.

I came from a iPad mini 2 (last year's model) to this tablet. As smooth as my iPad was I have to say I have very little if any lag on mine. It's runs beautifully for me. I'm OCD, any bit of lag would drive me up the wall. I really don't notice hardly anything. I'm still running bone stock everything minus using Nova launcher. Don't even feel like I need to root or flash anything. Although I'm going to once there is a root released for my model. Maybe I'm just lucky I don't know. Have had zero issues.

I'm used to an overloaded gs3 so this looks ultra smooth to me [emoji3]
It lags more with multiple user logged in, always reboot of you don't need the additional user

For example, this thread's website lags a great deal in chrome beta when scrolling. Other sites aren't too bad. Newsstand is the worst though. Are you using the stock broswer?

This site does lag a little when scrolling. That I do have to admit. For whatever reason it doesn't really bother me however. I've never noticed any scroll stutter on stock android so I attribute it to touchwiz. This thing debloated or running a custom rom probably flys. I imagine any scroll stutter would be gone at that point.
I use the stock browser. I was never a fan of chrome. I know that on touchwiz your going to get the best performance from the stock browser unless there's a fix I'm unaware of which could be a possibility. Newsstand I actually haven't used so I can't speak for it. TouchWiz is just eating up so much ram. I'm like always at 1.5 to 2 gigs of ram with nothing running (other then the tons of unnecessary system apps I can't terminate) That is pretty ridiculous to me. Is touchwiz smooth as stock android? Definitely not. But I really have little to no lag other then scroll stutter on certain sites. I'm still going to root and debloat this thing when it's available for my model so I can truly experience the power of this tablet.

Lol, chrome sucks

It's about time Samsung optimised their flagship device. Had 3 since July and they all lag, stutter when scrolling and render pics poorly. Nova didnt fix the problems and changing some apps like using chrome beta marginally helped.
About time they fixed this via an update rather than just forget about the device and launch more/different models. Samsung will always fail unless it focuses on a core product set and spend the time making the hardware work properly with the software.
I was attacked when I first got my first device for stating lag. Whether an first time user or someone who doesn't want to root (glad I didn't after having 3 replacements), I shouldn't have to kill apps, install different roms and root.
Certain other OS fix problems like these quickly. Where's support from Samsung??
I have the note 4, their es8000 led TV, fridge freezer and various other bits so I'm not a Samsung hater by any means, just someone who expects upgrades to fix problems.

It's hard to determine how much lag is there until you run the same apps side by side with another tablet.
Over Xmas I got a chance to do just that. Ran S 10.5 side by side with my sister's nexus 7 2013. Both running kit kat (hers is 4.4.3 instead of 4.4.2).
Play Store and chrome both run smoother on hers, less jerking and stopping when scrolling. Tapatalk about same. She has Google now launcher, feels faster and smoother than nova launcher on mine. Overall, every thing just feels a little smoother and more fluid.
Granted, the nexus is 1920x1200 so it's pushing fewer pixels around, but the nexus is one year older and I paid $179 for it vs $379 for the S.
I think Samsung slapped on the OLED display and said heh, good enough. Which is true because I bought it

Custom Rom?
I made a rom that is all stock, just a few optimisations. Better performance, better batterylife and so on, here you go:

I'd use only stock browser, if it had a full screen option and some gestures, but nope.
My alternative browser is maxthon pioneer, it has everything but stutters a lot

I've had my S 10 since August....I don't like chrome, never have, but after reading all this I opened chrome and came to this forum and I see no issues at all. NONE, other than I don't like chrome
I'm stock not rooted or ROMed. I have Apex launcher installed since day one and disabled all the Samsung and google bloat I could disable.
I have no issues with this tablet other than posting on some forums is a little quirky but that's just the way things are. I normally use Dolphin with the Jetpack or Boat Browser for tablet.
I love this tablet! Sure beats the stuffing out of my Asus TF700T! What a total POC that is!

Don't worry about the Lag
This lag on Tab S is only temporarily, the Android 5.0 will get rid of 90% of the lag. I know this for fact because I have Note 3 with Touch-wiz it lags often, after installing Android 5.0 I have NOT ONCE run into lag after 1 month of using it.
As of now, the Tab S is supporting android 5.0 cm 12 which there should definitely be no lag but again its unofficial ROM as of now, there are still things they are working on. Samsung's android 5.0 will get rid significant amount of lag, because Android 5.0 have 60 fps animation smoothness, and efficient RAM usage.
I've also heard rumors Samsung is working to refreshing their Touchwiz Interface with slim amount of lag. So, the future is promising.
As of now, if you really can't stand the lag, Install the Android 5.0 ROM for Cm 12, there are afew things not working in their such as Camera, NFC or something else, but the usage should show NO LAG!!!

Cyanogenmod for Galaxy tab S??

Are you using Android N Preview or Not . Why?

How many of you are using Android N and you are not ,why?

Yes, bit laggy using some apps but nothing that makes me upset, as long as i have my phone calls, emails and whatsapp running i'm happy. The next update i hope will fix many issues and most importantly the lag problem.

No, largely because of the lag. I've been spoiled by the smoothness of the stock ROM, to me the preview was basically slowing down constantly.

Ill use it when pure nexus comes out with a build.

Yes, I am experiencing zero lag with Preview 2 and will flash Preview 3 as soon as its available.

Yes, but experiencing a lots of lags, like when turning on wifi after wake up, upating apps, and much other random lags.. hope DP3 fix this.

Stutter?

Is it just my phone that stutters quite frequently or is this just a general problem with the m9? All the reviewers said something along the lines of "this phone is a speed beast" or something like that but I hate the stuttering. My brother's Nexus 6 is time and time again smoother than my phone. For example, when I go on nova launcher with a vertical scrolling app drawer and scroll, the m9 stutters when scrolling while the Nexus 6 is at a constant 60fps. Yet when I looked it up online everyone said the m9 was faster. Also, could this be a problem with the ROM, would I be better off with a custom ROM such as CM or ADHD? This lag is especially annoying since I paid good money for my phone
Is it just my phone that's bad or is this the snapdragon 810?

try to play with scrolling options in nova settings. there shouldn't be a problem normally, also be sure to keep power saver off, it will make the phone lag and stutter/slow

I have power saver off and changing the settings does no good, I still get small stuttering when I scroll, although since I got custom Roms it's been reduced, it's still there. But thanks anyway

I think I have a fix, basically I was going through the kernel settings in my ROM and I turned all my cores minimum frequency to 768mhz and now when I run nova I get 0 stutter and lag, I'm guessing my phone was just turning the core frequency down too much, this still doesn't explain why you don't get lag but I guess a fix is a fix. Since getting 60fps everywhere on my phone I'm in a sense of euphoria, also do you know a way for me to manage my CPU settings on an app basis
