Hi guys
I have had a Kindle since Xmas (actually 3, first 2 had hardware problems), rooted it the day I got it and hacked it every which way.
Interestingly I have noticed very little reference to graphic slowdown on the device (on these forums and on google searches) when pertaining to effects on the device.
Every time I install either a new ROM (CM7) or a rooted stock with a third party launcher (Go Launcher and ADW launcher) the interface is initially smooth and responsive. After a little time though it gets jerky and laggy when navigating the desktop and apps (mostly transitions IE zoom, scrolling etc). I should note that I am extremely sensitive to FPS slowdown, I can see frame rate drops when others usually can't.
Keeping this story short (and without going into all the details trying to troubleshoot the issue such as cache purges, background app termination etc) I isolated the problem to the CPU Governor. I tried doing some research on the hotplug governor but no one has published information on this particular governor, even though it is included with CM7.
I have enabled it, and it seems very similar to the default ondemand governor but I am guessing the polling interval for CPU scaling is faster. It scales down to 300Mhz and up to 1GHZ when under load (tested using Antutu CPU master Free available on the Android Market). Because of the (hypothetical) polling it may drain battery faster but that is something I am willing to sacrifice for a smooth interface experience.
Seems to have solved this annoying problem so I thought I would share for anyone else that may be bothered by this!
I am glad CM7 allows you to set the governor though its settings, a stock Kindle unrooted would give the user no control over this
I have used both ADW & Go Launcher and had experienced this issue with Go that I had not noticed when I used ADW. Anyhow after enabling the UI homescreen tweak in Auto-killer launcher performance seems to have greatly approved. After reading the above post I installed No-frills and changed the Governor to Hotplug and selected Noop as the IO Scheduler I am also noticing an improvement.
I Recommend the Use of Go Launcher EX or Launcher Pro
They are really fast and could be modified alot to work with your customizations
I just got iconia 2 weeks ago and its not refurbished however I feel it is slow web pages take 8 to 12 seconds to load sometime if I'm performing any task it is stuck for 6 to 9second no response n then it works fine. There is a lag usually for 5 to 7 second. Is that normal I didn't root my tablet didn't install a whole lot app yet I just little bummed due to the lag n slowness. Any thing you can suggest or share your experience.
Many thanks
I'm not a fan of the stock browser. It tends to lag and has rendering issues. You might want to try Opera Mobile. ( be careful not to download Opera Mini- it's intended for phones) I've been using it for a week or so and really like it. Better rendering, smoother scrolling, less crashing.
I use dolphin browser works good.
bad browsing experience
I have tried many of the web browsers on the market..
My experience is Some view some sites better then others. I use the stock browser for most sites.There is NO real solution to this issue.avoiding portal type websites. Such as yahoo.com helps. if you need content from there or similar sites YOU can d/load there app from the Marker.
Also try this.. Advanced task killer app .This tool should not be allowed to auto start and run in background. but can be used to diag. a rouge app.
Get Advanced task killer from the market..
try opening it from time to time and see what apps are actually sitting in the TRAY. if you see some apps that you installed and have not used since your last reboot. try killing them and see if this helps.. Use this Tool for one app at a time. If you find the app causing the sluggish internet. See if you can adjust settings on it . Maybe tell it to not START to not push notifications and so on..
NOT All apps play nice . you might just have one of them that decide to steal bandwidth on a constant basis.
Good luck and we all feel your frustrations.. I will point out runny task managers in the background is BAD IDEA. not all apps setting in the try are actually running Many are static and waiting for your input..

I don't experience the lag you are posting about. You may have a misbehaving app on your hands.
I too have experienced random sluggishness at times with the stock browser. Its especially bad on javascript-heavy sites. My bigger complaint, however, is the random typing issues I have, like goofy text selection and seemingly stuck shift states on the keyboard.
This appears to be a problem with the latest update. Beforehand, this lag simply was not there. Some sites (XDA Developers being one) lag with the banner ad at the top loading. This happens on almost EVERY vBulliten 4.x forum. I think a lot of us are hoping this issue will resolve with ICS, since it's doubtful Acer will do much more work with HC.
I will echo what the others have said.
When I first started messing around with my A500 I too noticed a small lag. My solution was to root my device and load a ROM from the ROM list:
http://www.acertabletforum.com/foru...-a500-501-rom-list-updated-29-jan-2012-a.html
Most of the ROMs work much better than the stock android that comes installed on the A500. Also once I had pretty much cached the sites I use the speed issue vanished.
The stock browser lags. Especially when you use your keyboard (there are some videos on youtube) other browsers does not have this lags.
Hello, I just installed the stock ICS on my Xoom, and I'm disapointed ...
As everybody was saying "the Xoom is now a whole new device", I was expecting so ...
There are good points with ICS :
- new functionalities like icons directories.
- gpu acceleration for a few 2D applications.
- a few websites are now smoother.
- typing texts in forums is now fast.
- a lot more available memory : around 512Mb instead of 400Mb in 3.2.1. EDIT : since a reboot of my Xoom, the available memory dropped down to 360Mb !!!
But I was expecting a lot more fluidity, smoothness, from the 2D applications of Android.
- the new market is more laggy than the one of honeycomb 3.2.1.
- some web pages are smoother now, but some other are slower !!!! XDA for exemple lags more than in 3.2.1 !!!
- the 2D GPU acceleration does not work for all applications : even when "force 2d acceleration" is selected, some applications become smooth, some other don't, even when they are the same kind of applications.
- stock web browser crashes more than in 3.2.1.
- on stock browser search string on some forums don't work anymore (try on XDA !), same problem with some dropdown menus which let the web page disappearing ...
- the new kill apps system in ICS does not really kill all apps. So we still need an app killer.
- the portrait mode is still laggy compared to the landscape mode.
- the available memory, when the Xoom has just been rebooted, vary between 510Mb and 360Mb ... !!! With absolutly no change in my Xoom configuration.
- When you force OFF the screen rotation in landscape mode, if you lock the Xoom and put it in portrait position, when you unlock the Xoom the display will be in portrait mode, and right after the Xoom will be unlocked it will go back to Landscape mode. This bug didn't exist in Honeycomb.
- the cursor to select text to copy seems more difficult to position than in Honeycomb.
- if you kill the stock browser with an app killer, when you relaunch the browser it will then open the last visited website, which is as expected. But if you kill the browser with the Android task killer, then the browser (when relaunched) will display nothing.
So I don't feel like I have a new device, some things are better, some worse.
As I am very concerned by the Android fluidity, ICS is a big step forward, but there are still some more steps to do, and I hope we will be able, one day, to see Android as fluid as an ipad on our Xoom ... But I guess I should stop dreaming.
Maybe you should trying running one of those custom ROMS and see if you see and
better performance or features..it's worth a shot
I think even Stevie Wonder saw this thread coming.

You may be right but I would expect Google to optimize more Android without the need of tuning a custom Rom to gain (maybe) a few more images per seconds ...
With this thread I wanted to ađvise people who are still waiting for the ICS update to minimize what they can expect of it, this way they may not be as disapointed as I was...

No.
Most of the stuttering is caused by apps which are written by developers who don't really understand Android,
Seriously.
Pay attention to which apps aren't responsive. Look at memory use, wake locks, watch for unnecessary services and background threads.
Eliminate apps one-by-one until stuttering in menus and the desktop stops. Don't run live wallpapers.
Factory reset. System settings from prior Android revisions can cause problems.
I have fixed many of my friends' Android devices when they blamed the device or OS for lag.
Stock 4.04 is quite responsive and fluid. If yours isn't, it's probably the apps you've installed or settings conflicts.
Change animation settings under development to none or at least down to .5 from 1.0.
Use a third party launcher and third party browser if unsatisfied with stock. We have choice...we can use it.
My Xoom is as smooth as butter...no lag or stutter at all.
I always choose the apps to install according to their fluidity. I know some apps are badly developped. I also have no apps running in background (that's why I choosed the stock ICS), always killing running apps before running a new one. I also don't use animated background.
I do my best to let my Xoom run as smooth as possible.

Have you changed your animation settings under Developer Options (in Settings Menu, toward the bottom) If you don't need animations, then change the settings to "none" it will make a difference.

Thanks for these advises but the problem for me is not the speed of the device but its fluidity. So changing the animation setting did change the speed of the way the menu are displayed but not the fluidity of the animations.
About the fird party launcher, I think it will not make it run smoother as it will run in the background and occupy memory.

Why, I don't know, but I have always found increased smoothness from launcher like ADWEX. As they say, "your mileage may vary." The configuration in my signature represents what I think is probably the best, smoothest and fastest combination I can find. I also have tons of apps and a pretty elaborate theme and still my Xoom is butter-smooth. It can be done.

Why kill the apps before running a new one? If you are choosing apps based on how well programmed they are that seems completely unnecessary.

Hi,
You didn't mention what apps you are running.
I'm running 4.0.4 stock rooted - and no issues in general. It got very laggy once after running for a week, but a reboot fixed it. Like any OS, very complex and not perfect - reboot once in a while.
I honestly don't find ICS to be very much different than HC (nor did I expect it to be). (ICS is what google wanted HC to be but ran out of time, so released HC)

Adw auncher makes for a much smoother home screen experiance than stock. Stock struggles with more than a couple of Widgets. Its a diferant experiance, but definatly faster.

Which is why you were so quick to see my original suggestion as a personal attack?

I thought you took it as a personal attack because you said "stop using crappy apps", which to my point of view is agressive.
That's it. I'm sorry if your goal was not to be agressive.
You know, there are lots of fixes for any problems this device had at one time, but many require rooting and installing custom roms/kernels/recoveries and certain non-stock apps. I realize that some people like staying stock as much as possible...I don't. I want to get root immediately and start customizing. That's just me. Some people don't like to eat meat...I do. Some people can't imagine not driving everywhere...I've never owned a car. We're all different. But sometimes you just have to understand that your desire to stay all stock comes at a price. Lag exists. That's why custom roms exist...to eliminate lag, among other brilliant things.

OK, so I'll check the custom ROMS ... Can anyone specify which ROM is the best for fluidity ?
I didnt have or notice any of the problems you had on stock ICS
I am running the following rom on my xoom atm and have had no issues

Has anyone noticed a painfully slow lag when using Chrome to browse on the s7 Edge. I I've deleted cache and data, to no avail. Flashfox works fine.
My chrome is terrible, i've done all you have done too and it is still terrible. I can use the stock browser with no problems.
Stock browser is most smooth yes. Chrome is kind of choppy on this phone from time to time.
I rooted it and installed adaway.
Installed chrome beta, now its alot better
Stock takes 2-3 seconds to load a big page, chrome would take 6-7 seconds, that is not worth even using to me.
Chrome drains my battery a lot (continue active in background), I just uninstalled it.
Also had really bad performance on Chrome. It runs a lot better on my iPhone 6s Plus than on my edge
Ah Polly if you have a lot of tabs open for sure but I would just use a better browser. Unless you use chrome to sync between your computer and your phone. I use UC browser. Pretty good speed and video downloading and etc..
I'm using RSBrowser, which is basically chrome but optimized for an SD820. Some of us (Verizon) don't have the stock browser.
use stock browser with ad-block fast..it`s seriously faster then my desktop pc browser! chrome is really bad IMO.
Just wanted to chime in and say Chrome on the S7 is terrible. I mean absolutely abysmal. A page with an embedded video basically locked up the whole browser. And scrolling is so choppy it makes you want to throw your phone away. Stock browser is awesome and smooth, but it lacks crucial plugin support.
I don't use Chrome since quite a few months ago. It has become one of the slowest mobile browsers around. But even FireFox is slow, not sure why. The stock browser is blazing fast though, and that is enough for me (it also supports ad blockers since recently).

I was having the same issue with Chrome on my S7 Edge (mainly the device taking 7-8 seconds to load up any page), but I finally found the culprit!
I disabled 'Safe Browsing' ('Settings' > 'Privacy') and it's flying. Pages load instantly now.
Give it a try and let me know if it helps!

This made a huge difference, but still thinking of switching to Firefox. Chrome is starting to get bloated and crashing on all my devices.
Using an A2017U B29 stock rooted. I find the phone to be generally laggy, especially in opening apps or switching apps, but even in things like SwiftKey appearing… My OnePlus One felt faster. And also (separate issue, I understand) double-tap to wake is slow, as is screen-on in general.
Please share your tips for speeding up the phone. If you can include links to tutorials or explanation threads where relevant, even better!
Thanks :good:
That's sorta unanswerable but my first cheap tip is to disable window and menu animations. I imagine some manufacturers tweak the timings so you don't feel the lag- I mean... animations are intentional lag, right?
Just go into developer settings near the bottom and turn them to whatever the next to lowest setting is. Personally I just disable the 3 animation settings because they're dumb. A window fade-in/out effect is telling your computer to do a math equation each time you switch a window. I'd rather the window simply open.
The same goes for 3d and transparency.. Unnecessary math. Even Microsoft got rid of the Windows Vista orb start button in Windows 7 because it shaves a few cpu cycles off to render a square versus a circle.
get fstrimm from the playstore
Thanks! I had turned off some of the animations already but turned off the other two now as well. Didn't see a big difference. Not sure how to turn off 3d and transparency (and wouldn't that affect how apps look?).
Moved my photos and videos to the SD card… that helped, too.
[comment moved]
Thanks — I did. Not sure yet if it made a difference... Moved my photos and videos to the SD card… that also helped.
Upgrade to the ZTE Axon Dmix7 custom ROM. You can dirty flash it and continue using your software since it is just an optimized Stock ROM. It is by far more agile than the Stock B29. It is fully reversible, since you can also dirty flash the stock B29 ROM again.
On top of that you can increase your user experience by more than 10% by reformatting your data partition to F2FS. This process is also reversible and very easy following the guide you can find in my signature.
I am using AKT kernel tweaks for SD820 since 3 days. My phones feels blazing fast now, and batterylife improved too. Check it out!
