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.

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.

Android DP11 issue with launcher

I have been using Evie launcher even with DP11 but with recent update few days ago it is borked, even though I set it as default launcher and when I try to get recent apps by clicking on square in dock it FC's and when I look at app info in the fc warning it shows as pixel launcher not Evie, I did factory reset as well but it did not help, any ideas.

The Pixel Launcher still handles app switching even if you use another launcher, and its been broken for me too on DP4.

Nova Launcher

As much as I want to use Nova Launcher, it's just not as smooth and quick as the stock Pixel Launcher. Anyone else feel this way? At the same time, I have a love/hate relationship with Pixel Launcher because I love having the icon unread notification numbers on Nova as well as being able to change the home screen grid size. In the end, though, Nova is just not as quick loading apps and the app drawer.

I agree Google isn't making it easy to use another launcher on Pixel phones. It's a shame.
Nova is definitely not as smooth as the Pixel launcher. But Nova has so many advantages for me that I'll take its options over overall smoothness any day.

Same here.

U guys can use one plus launcher, one UI launcher and a custom pixel launcher as well with More customizations. There's a thread on telegram.

Action Launcher does pretty much everything Nova can do and it does everything stock pixel launcher does too. Including copying from recents screen and using Android 10 gestures.
Launchers can add the ability to work correctly on Pixels, Google opened up the ability for 3rd party launchers in December, Action Launcher is only one I know of that can do it without using quickstep or magisk.

The ones I'm referring to don't require quickstep either, just flash in magisk

Fully aware, just providing more options

I keep seeing these threads where at least one person claims Nova doesn't work correctly. Last year, I would have agreed... but I've been using Nova for months and I have forgotten about any drawbacks if there are any. The only differences I remember are a couple animations and the recents menu doesn't have suggestion icons? (which never suggested apps I wanted to use, so I don't miss it)
What's the smoothness that people are complaining about? The animations run as fast as my finger pushes things around... Is it just the quality and type of animations? If so, I want functionality far over such things. Having to use substratum/magisk to customize the Pixel Launcher was way worse than recreating my layout in Nova. If only things like TeslaUnread were still officially supported... but Google likes killing off useful things.
Feel free to help me understand what I'm missing.

Nova says in the settings that Google has not made it possible for Nova to use Android 10 gestures correctly. Google has made it work, but Nova hasn't been updated to allow it yet.

In my opinion, the warning is wrong. Back when I first got my phone, like half of the gestures didn't quite work. Now everything works for me.
At Nova's homescreen...
Swipe from side: Isn't triggered because you can't go back from home. Just flips pages.
Swipe from bottom: Opens app search. I'm not sure if the gesture is doing this or Nova is.
Swipe from bottom & hold: Opens recents.
Swipe from corner: Shows assistant overlay.
Everything basic works. I don't have palm swipe screenshots enabled.

My issue with Nova is the delay going back to the home screen. I can't immediately open another app. I always have to wait an extra second or click on app twice before it opens. I want the full pixel experience and it seems that Nova doesn't always deliver on it. I do occasionally go back to it until I get annoyed with my first statement.

Honestly, I've never noticed this. I guess I go home before I know what I want to click on and so I'm never quick enough to see it.
The way it's acting, it reminds me of a paused activity that needs to refresh when the app gets restored. I tried to disable battery optimization for Nova, but it didn't help. I'm not sure how to solve that.
I tried the same test on my old phone and pressing the home button actually does nothing for a split second, then Nova shows and responds immediately. But when you gesture, you want it to happen immediately... not a split second later. So in that way, Android 10 and Nova do the sensible thing and shows the paused activity.

I was using Nova Launche a lot of time ago! let's going to check how does it works now!

I have no reason to use any other launcher than pixel launcher. It works just as I need.

not sure what the hoo-blah is. I have been using Nova prime beta with no issues. No problems returning home... No speed issues. The warning that is in there is talking about the gesture navigation system wide not inside the launcher. So this means you have to use the classic 3 button method to navigate (back, home, recent). IMHO this does not affect the experience at all. Definitely prefer Nova and the customization over the stock launcher. :good:
Edit:Actually just changed the nav settings and Nova is working with new gestures.

I just switched back to Nova from Lawnchair on both my S20+ and Pixel 4XL. Nova works beautiful now and Nova Google Companion works with dark mode.

I'm on Android 11 Beta and am running Nova with no problems with gestures at all. For some reason on 10 they were not working as smooth and I would get some lag going back to the home screen. On 11, those problems have seemed to disappear.

While that's true, the closing app animation is not there and feels weird. ( Using gesture navigation )

Lag when using Nova Launcher?

I just noticed there's some lag in Mi 10T when using Nova Launcher as the default launcher. For example, when changing apps in multitasking or going back to homescreen.
Also, when Nova Launcher is set as default, you lose the gesture to go to the previous app swiping up from the bottom and then right.
Any solutions?

Gestures don't work at all in custom launchers, that's a limitation of android 10, and 11, and without rooting there is no solution for now. As for lagginess that's again using other launchers. Try and find one that doesn't lag (nova doesn't lag for me, but I'm using classic 3 buttons navigation because gesture nav doesn't work...)

You have to find the way to get nova launcher to behave like system launcher (delete miui launcher and put nova in its place) to get gestures working. Check on internet, there's tons of guides on how to make system launcher, or maybe there is some magisk module that does that...

I just tried that and made Nova a system app, then I deleted MIUI Launcher. It behaves the same. Switch between apps from the bottom (Android 10 native gesture) is not working. I'll just have to stick with the MIUI Launcher then, though I hate to see icon labels in home screen...

I feel your pain.
Same deal on my Note 10+... those damn white labels. That's all I wanted to change.
Nova Launcher does slow it down as do many others if it already has a good stock launcher as the 10+ actually does.
Nova used a lot more resources/battery than stock too.
Take any launcher instability seriously.
After hyperion boot looped me twice, yes two full reloads worth of fun, I decided I could live with the white labels.
My need for speed and system stability is much greater...

Android 11 constant crashing

Hi, I'm on a Samsung Note 20 Ultra with Android 11 and Nova Launcher keeps randomly crashing. When I tap on an app icon or try to open the app drawer, it just stutters and does nothing, then you give it a second try and it normally works. But it happens so often that I had to uninstall.
I'm using Nova Launcher Prime 6.2.18. Is this a known issue that will probably be solved in version 7? In that case I might try the beta

I'll reply to myself here because this is what happens:
Nova Launcher
The premier custom launcher for Android, loved by over 50 million.

For the moment you basically need to choose between Nova Launcher and gesture navigation... I'll think about it.
