[Q] Slow Home Screen Refresh

I have a stock, non-rooted G2, running GB 2.3.4, which I love. The only complaint I have is that the home screen often takes a while to refresh when coming back from another app, or even when turning on.
I'm using the stock launcher, I have seven screens, and 8 or 9 widgets that need to refresh. It doesn't seem to matter whether I've recently cleared my cache or not, or whether I have animations on or not.
Similar threads from other phones suggest there may be settings somewhere to improve this performance, although I probably don't have that app loaded... Any suggestions?
Thanks in advance...

You're close to maxed out on home screens and widgets so it's expected to have a lag when coming out of an app. The stock launcher *may* have some tweaks (it's been a while since I've used it) but most third party launchers have a "keep home screen in memory" setting which speeds up coming out of an app and back to the launcher.
Really though, I'd suggest trying to slim things down a bit. I know it's fun and all to have widgets for everything and apps sorted into home screens but there comes a point where it becomes faster to do things "the old fashioned way" than to have widgets and screens lagging to do it for you.
For example, I have three screens; my main one (clock/weather widget), my most used apps (phone, mail, messages, voicemail) and my camera/video camera, another screen for social apps and another for note apps and daily utilities. I also hide all the apps I don't actually lauch manually (URL shorteners and other "share to" type apps).

Launcher Redraws / Reload

I've tried the V6 supercharger script, nova, and apex. NONE of them eliminate launcher redraws. It's so annoying!
The only launcher that provides a smooth stock experience with no redraws is...the stock launcher. Why? I love the features of the other launchers, especially being able to back up my homescreen. But the redraws kill the experience. Why is it so hard for aftermarket launchers to replicate the experience?

Whaa...

Try adding this to your build.prop. I had the same problem and this little tweak locks the home screen in memory works great for me. Pay attention, that you don't mess something up in your build.prop!!!

I believe Apex has the option to lock the launcher in memory, if not do the build.prop tweak in the post ^ mine.

Try a less intense kernel too.

Wow. My nova launcher rarely redraws. Rarely. And when it does its quick.
let it be.

Laucher reloads and redraws are the results of Androids wonderful memory management. You'll have to find a launcher which locks in the memory, but by doing so, other apps will auto-kill faster than usual.

When I run nova or anything other than stock launcher, system panel shows its process as "perceptible" and using 40mb of ram while stock launcher has a process running too. Essentially I find its running both launchers, being more prone to kicking it out of memory.
Also on 4.0.1 this happened with the stock launcher getting redrawn. On 4.0.4 it seems to be fixed almost completely.

I still don't have perceptible in my sys panel and my nova usually hovers around 42ish and Max around 50. But I did buy the nova prime and set it as default. No sign of the other launcher unless it is system UI which hovers around 25mb.
let it be.

Yeah I'm jealous then. I been messing around tonight and can't get it to stop showing like that.

This is why I freeze/uninstall all launchers except the one I'm using in Titanium backup. Though you shouldn't really have to, because Android should kill off the old launcher process eventually (when it needs more memory for something else) and it shouldn't return unless you manually switch back to that launcher. But I freeze it anyways just to ensure it doesn't interfere with anything. I freeze a lot of other Google/Android services that I don't use too.

I have been using apex launcher since the beginning on my galaxy nexus. However after android 4.2.2 update, I found that redraws have been really frequent and annoying.
The same happens on my nexus 7, especially after using memory hog apps like the "new hangouts" (really, really poorly optimized...)
Indeed apex reloads always, after exiting from hangouts.
Recently I tried also nova launcher (importing all settings from apex, so my configuration is identical), and I have to say that nova has much less redraws with respect to apex (both on galaxy nexus and nexus 7).
For example when rotating the screen from portrait to landscape, I don't experience any visible redraw with nova, while apex was redrawing quite often...
So far so good, I decided to switch to nova, even if I liked apex really much

wetter app caused launcher redraws
I also had frequent launcher redraws on my GN... the issue came with Android 4.2 and got MUCH worse with the recent 4.3 update (i'm on stock rom).
yesterday I removed the widget from wetteronline.com's "wetter app" I had on my homescreen - and surprise! I could not believe it, did not have a SINGLE launcher redraw since then (2 days heavy use) what a relief...
so I still think it is a bad memory management issue in Android, but maybe it is worth trying if one of your apps or widgets is contributing to the problem.

[Q] How to lock 3rd party launcher in memeory?

Hi all,
The One X have this problem of re-draw all the widgets and folders in 3rd party home screen launcher when exiting an app. I've tried 3 launchers Apex, Nova and Go, they all have this problem, some re-draw more often than others.
So is there a way to lock launcher app in memory?
Many thanks
P.S. I'm running the lasted LeeDroid rom with Sense removed.
P.P.S. I love the hardware, but HTC sucks with software on this phone, this was never a problem with my other Android phones, and even after 5 weeks, we still having major bugs like SD space getting smaller for no reason.

Apex launcher let's you, go to apex settings then advance settings and at the bottom is the option to keep apex in memory

Thanks for the fast response, been a while since I used Apex, I tried the free version and it seems to work. I'll get the pro version so I can have multiple tabs in app drawer.

No worries, the latest update (1.29.401.11) fixed the missing sd space, I went from 14gig to 19gig free space just by updating

Hi,
It's a know issue for Apex Launche and Nova Launcher (maybe another Launchers?),at last for me it's not a Launcher issue...I posted this about "Launcher redraw" it's for Apex Luancher but maybe it's the same thing for Nova...
Personally I've never had "Launcher redraw" with both Apex or Nova and with LiquidSmooth rom.
Actually I use Nova and no "Launcher redraw",I have no apps or script which could cause this issue,I mean the Launcher is killed at a certain amount of memory used/free (RAM).
Apex have an option to keep it in memory,not Nova yet...
Maybe you can try V6 supercharger http://forum.xda-developers.com/showthread.php?t=991276 for adjust the Oom_adj priority and low_memory_killer settings?
It seems that there is also an app for keep the Launcher in memory:http://forum.xda-developers.com/showthread.php?t=1305060 with different settings...
First check your ROM feature (about init.d scripts for memory "tweaks") and maybe any apps you're using for memory settings (if you have one).Check also in developer option if "Don't keep activities" is untick and "Background process limit" is on "Standard limit".For me it's just a memory setting (the broad sense).
The post I posted about the "redraws",it's a theory or an idea,not a sure thing,a scientific etude or a proof:

Micro lag on nova launcher

Folks when using nova launcher there's a clear noticeable lag when launching apps from home screens.
I've tested this versus stock oneplus launcher. On stock oneplus launcher apps launch instantly after you tap on an icon, whilst on nova the app icon lights up & then the app is launched afterwards. My best mate who also uses a oneplus 3 has been experiencing the same issue.
To test this for yourself, use oneplus launcher for a minute, opening various apps - then do the same on nova and you'll immediately notice the micro lag.
This also occurs when launching apps from the app drawer.
Anyone else noticed this?

I also experience the exact same issue. Noticed it couple of days ago but haven't had time to post about it here.
I have reported the issue to the Nova Launcher Dev via email and also in the Beta Google+ page. This is definitely a Nova Launcher bug as I have tested Google Now Launcher, the new Pixel Launcher and the official One plus launcher.
On all three apps open the instant an icon is touched while on nova an icon is touched, the icon briefly lights up and only then opens. It is something you might not notice initially but once someone tells you or shows you, you can't miss it and it gets more and more iritating with time.
Have tried moving to other launchers but the uncustomisable grid size on Google Now, Pixel and Oneplus launcher keep me from doing so as most of them have massive vertical gaps inbetween apps on the homescreen.
It happens on both Latest Beta and Latest Stable version of Nova Launcher Prime. Have tried to remove all widgets off homescreen, turning off animations system wide, but it did not make a difference.
Running Official Rooted Stock with Viper4Android Oxygen 3.2.6. Do not use xposed so a module can't be the culprit.

Try changing scroll speed and animation speed to Fast under nova setting look and feel. Also in developer settings change transition animation scale, animator transition scale and windows animation scale all to .5

The problem isn't an animation problem. It is a delay that happens before the animation even takes plays. It doesn't matter even if you switch the animations off system wide under eveloper options the delay between when you tap on an app and it opening is still noticeable

Oh, ok. Mine is bone stock unrooted and don't have any stutters that I can see. Wish I could help.

No worries bro, thanks for chiming in :beer:

Can't say I notice anything more than the animation.

My nova beta with prime on stock oxygen 3.2.6 is as smooth as one plus launcher.

I don't notice it myself; that said, I'm using FreedomOS (slightly modified OOS) and blu_spark kernel, which might help improve performance a bit.
Most apps open up before I even manage to lift the finger off the screen, those that take longer are equally slow on both launchers. (Talking about cold starts here, once they're in RAM everything's pretty much instant).

It probably comes from the fact you can assign 2 different apps for the same icon.
One for "click" and one for "slide up".
If you slide up the app drawer icon you'll enter in Nove Settings for example.
"Not a bug, just a feature" ^^
Same thing with SmartLauncher.

I'm using Nova since two weeks with RR and Boeffla's Kernel, and I have no lags at all. I've set the animation of Nova to "Fast". When I open the drawer, or the widget menu, I can't notice any micro lag. I think this problem is not Nova-related

That shouldn't cause any lags, sliding and tapping are completely different actions.
Lags or rather delays happen when you have double tap functions, because in that case the system has to wait after first tap to see if you'll tap again. But sliding has no influence here.
I'm using swipe-up functions on multiple icons and still see no lag whatsoever.

He said "micro-lag" not huge lag. But you're right, those are two different things
I just checked on my device and I have a little latency due to the animation (just tried to change the speed animation and it fixed it).

I can confirm this lags on RR with Nova launcher, Trebuchet open the aps faster!

Doesn't happen to me on Sultan's ROM.

The lag is a MICRO lag not a very noticeable lag. Any other launcher including, google now, pixel, one plus and action launcher 3 don't have it but nova does. doesnt matter if your using stable or beta builds. Makes no difference what home screen set up you got. There is slight delay between when you touch the screen and the app icon you pressed starts playing animation. The app lights up first which it shouldn't do. it should just start animation the minute the app icon touchscreen input is detected. It is alot less likely to happen if the app is not in memory. Once the app is in memory it does it every single time you press home, whatsapp for example. Moved to Action Launcher 3 after using Nova Prime for past 3 years. Reported to developer via email and google+ beta page but no reply in 3 days.

noticed this since i got the phone a couple of weeks ago, but only if keeping app in memory (i.e. hitting home instead of back). if i hit back to exit app, this delay doesn't occur (except maybe w/ facebook)
only happens w/ nova launcher and definitely specific to OP3. i would use stock launcher, but i prefer to turn all animations off, and nova seems to be the only launcher that keeps the light up on button/app press with animations off.
in general, OP3 seems to lag a bit compared to my OPX in regards to navigating menus (i.e. settings)

I can also confirm microlag when launching apps, really annoyed with it.
