I have a Lenovo P780 dual sim since 1 month, bought on Amazon Germany, but shipped from China.
Have rooted it and added many other apps and deleted them when I didn't like them. I use the Apex Launcher. It has been perfect up until today. I wanted to move new app icons into the dock area underneath the normal home screens. I bought the Pro version of Apex Launcher because I thought the added functionality would allow me to do this. Whether or not this upgrade is the source of my present problems, I do not know.
The problem I now have is that once I unlock the screen, the normal home screen is now blank. If someone calls me the phone app lights up and I can pick-up and talk normally, later check my contacts, see the call and text logs. After the call, pushing the "Home" button briefly no longer works to bring back the home screen. Pushing the "Home" button for a couple of seconds brings up the running apps and lets me close it, then when returning to the "home" screen its blank.
Swiping down from the top allows me to seeing the settings buttons such as WiFi etc as it was before. I can click on the "Settings" icon to open the settings, but if I try to change the "theme" the app responds every time that it has stopped working.... Swiping back up returns the blank screen.
HELP please !!!

Hi. It seems to me that your Apex Launcher have one big proble. Try to install free version and see if this have this problem. Iff not this is a problem... Iff the free Apex have the same problem you need to change your launcher. Search another one on the market.

Sorry Stumpy, but I cannot use your advice. Since I cannot see my home screens, I cannot launch any apps. When I power on my phone I have no access to any apps. However if an email arrives, the GMail email app starts and I can then read and send emails. If I receive a telephone call, the native phone/contact/messages app starts and then I can also use these apps. But I cannot start or see any of the other installed apps, unless it has been prompted to start from outside my phone.
I have backed up all data and applications to my SD card using Titanium Backup before this problem started. I have reset the phone using the internal red button, used the settings menu to restore the data and apps, but nothing helps. I can change the Wallpaper using the Settings icon I can see when I swipe down from the top of the phone but when I try to change the Theme, the Settings app responds with "Unfortunately System UI has stopped". (This always happened since the phone was new - so I then downloaded Apex Launcher to go around this problem)

Hi Stumpy
I managed to get my phone back!
I used my desktop computer to send myself an email with a link to another launcher (Go Launcher). When the email arrived on my phone I could then click on the link which gave me the chance to open the link using Google Play and then install the new launcher. Once the new launcher was installed, I could see everything again, except that I then needed to put all the apps back in the right places. Wow am I happy !!
Thanks for your time and trying to help me!!

I am glad that you manage to resolve the problem. Be carefull next time when you spend money on apps. Try free versions first time and install custom recovery for your phone. They are the best thing for backup.

Hey all,
Just got my new OnePlusX and the first time I turned it on it prompted all the set up screens. I had to skip through them all because the keyboard would not stay open. It would open and then immediately minimize. Not a great start but no problem, I'll add my accounts and connect to wifi later.
Once I get into the 'home screen' I could see my status bar at the top but no icons and no way to access the app draw. I pressed the capacitive buttons and opened the notification slider which both worked and eventually got into the play store. From here I installed an app or two and got prompted to do a system update, which I did.
After the update I was hoping my launcher would work.. it didn't. The home screen is a black screen with the status bar at the top and no icons - the home button seems to do nothing when I'm in an app and press it.
I installed a third party launcher which worked - I now have a home screen and app draw. However, after opening an app, it crashes after a second or two (chompSMS does this as well as messenger, phone and contacts which are stock apps).
Does anyone have any information about this, what can I do here?
I know one option might be flashing a custom rom but being a brand new phone that should most definitely not be something I have to do to be able to call and message people..
Update: I ran a factory reset and all problems seemed to be resolved now. Not sure what was going on but I guess something happened that a reboot couldn't fix. I'll leave this post in case it helps others.
Have you done a factory reset after the system update??

Is anyone else having trouble using gestures with third party launchers? For me, they work just fine and then after some time it reverts to buttons and I get the message "System navigation updated. To make changes, go to settings".
Searching around, it seems like people on other phones don't have this problem anymore.
On a different note, I started using fluid navigation gestures (FNG) and I preferred that since I could add more gestures. Problem is if I'm plugged into the dual screen case and I turn off the dual screen - either by turning the screen behind the phone or manually turning it off - and use the notification shade, then the buttons come back and hide and FNG is disabled until I start using the dual screen again.
Anyone have any solutions?

Same annoying issue! I think it happens every time Nova gets restarted but not sure on that. I've searched for a resolution too and can't find one. I tried creating a tasker profile to make it easier to switch back to gestures via a quick setting but it doesn't work. The secure setting to change is navigation_mode value of 2.

Nova shows you an explanation right on the settings page of the problem. Google has not made gestures 100% compatible with 3rd party launchers and there is nothing devs can do until Google gives them what they need
Yes, I've seen that message. I've also seen that Google delivered this ability in December of last year and that some users have this working fine. It's different from when it would gray out the option to use the gestures. This one feels like LGs software is the one resetting the gestures since the notification is titled System UI.
I'd be fine with any solid gesture solution as I'm not mated to the built in gestures, but it seems like others break due to the dual screen. Meanwhile the built in ones fail. I could of course change back to gestures every time this happens, but it feels like I'm using a beta device in this regard.

I don't think it's LG. My wife has the same issue on her Note10, and I have it in both my V60 and my OnePlus 6t all using Nova. Maybe another launcher has implemented the fix?
So far for me Action Launcher seems to be working ok with gestures, even after a reboot. I prefer Nova but this is close.
edit: Dual screen causes the navigation to revert back
I'm sure some of you have experienced the Recent Apps button (3 button navigation) not working with 3rd party launchers (Nova, Microsoft, etc). The only fix I have been able to find is to switch the default launcher to the Pixel Launcher, and then back to your 3rd party launcher of choice.
Luckily, I have been able to replicate this problem consistently. While using a 3rd party launcher (Nova launcher in my case), open any app (and only one) and press the Recent Apps button 3 times quickly. The Recent Apps button should stop working. It does not break when there are no recent apps or when there are 2 or more.
Hopefully, this information might be helpful to minds smarter than my own.
If anyone else is experiencing this or is able to replicate the issue as well, I'd like to hear what your setup and experience with the issue is.

I've been using Nova on my P6 since I got it, until 2-3 days ago anyway when I decided to try Gesture Navigation instead.
I've never had the issue you're showing, not a single time. What I DID encounter a few times is that instead of the proper Recents overview when tapping on Recents I'd only see a weird view of my homescreen, like when you longpress anywhere on the homescreen, except that it was ONLY the homescreen and no settings/wallpaper or other options. That happened randomly and was hard to reproduce, but I've never seen the issue you're showing in the video
Did you import/restore any apps/settings, esp. for Nova, when you set up the phone? That seems to cause a lot of issues when coming from a non-Pixel device. I hard a weird glitch were the display would briefly light up every 10-20 minutes when the phone was just sitting there untouched, a factory reset and fresh install of all apps fixed it.
Maybe try that too?

This is a fresh install of Nova. I Imported all my apps from my Galaxy S10+, so I'll try that and report back with results.
Other than that, what do you think of the gesture navigation? I pretty much wrote it off as soon as I got the phone.

I've never been a fan of it, never used it before and still don't like it. The only reason I'm trying it again is because I'm still not rooted and simply can't stand looking at that ugly white navbar (yea yea, I know I'm weird ). It works I guess, but getting to Recents for example is a hit & miss with gestures, navbar is much more reliable for me.
Whatever your issue is I hope you get it sorted

I can replicate this on my P6 also, 3 taps and recents is broken. I have to change launchers or power cycle (reset) to get it working again. I originally imported settings and apps from an LG V35 10 days ago.

FIX!!!!!!
Settings > System > Developer Options > Animator duration scale
Turn to 'Animation off'
The Window animation scale and Transition animation scale has no effect on this.
After changing this, I have not been able to replicate this issue.
My best guess is that the recent apps button is pressed while the animation is still going, and the phone has the electronic equivalent of a mild stroke.
Can anyone else confirm that this corrects the issue? I haven't seen a solution like this on any of the many threads about this.

Turning animation off prevents the 'recents' button failure, but I wouldn't call it a fix since then animations won't work. Personally I will keep animations set to .5 and try not to press 'recents' too many times. The lack of animations gives the Nova UI a flat and amatuerish look.
This is a Nova bug, probably due to Android 12 incompatability, since it doesn't happen with the Pixel launcher. I guess we can hope that they correct it eventually.
Thanks for identifying the cause, I had this happen multiple times before I read your post and didn't have any idea what was causing it.

I have some shaky hands so I end up pressing the button a few times fairly often.
I think the issue is with Pixel Launcher. I have confirmed that this issue happens in other launchers as well (Microsoft Launcher). I also found that killing the Pixel Launcher fixes it too.

This. I have this problem where the recent apps don't show, and instead I just get a zoomed out version of my homescreen. This happens CONSTANTLY and is the most annoying thing about this phone. It happened to me on the stock launcher as well as on Nova.
Anyone know of a fix for that?

I did tick that, because I couldn't open my recents menu to close apps. I just unticked that option, and still have the same issue happen when I hit the recents button.
It zooms out to a smaller version of my homescreen, and if I swipe up it will close the most recent app, then show the rest of the open apps, if I just swiped to the right to go to another open app, the smaller homescreen slides to the right off my screen but it doesn't show the other running apps. It's almost as if it's having an issue drawing the image of the open apps.

Not sure I'd call it a "fix" but since I switched to Gesture Navigation instead of using the navbar it hasn't happened once. Maybe the P6/A12 does something odd with the Recents button that needs to get fixed through an update, no idea.

I thought that would fix it as well, so I switched to navbar (which I prefer anyway) and it is happening there too . A12 is just so buggy, it's annoying, I hate that companies use the public as their beta testers nowadays
Just noticed it today had it since launch day. Only change was the fingerprint reader update I did yesterday.

I'm coming from an LGV30, running Nova. I was planning to just import settings and apps to my P6Pro when it arrives. Did that ultimately work for you, or did you end up doing a fresh install of all your apps, including Nova?

Actually it worked very well, I was surprised. I used cable method that google recommended with the usb-c cable that came with the phone.
I have done LG to LG imports and Samsung to Samsung but never tried LG to Pixel.
I still had to do a lot of setup steps like passwords, set the home screen to Nova and handle the widgets. Be sure to go the play store and do an 'update all'. But it was much easier and quicker than doing a clean install. I figured I could always do that later if I suspected something was not working.
There are issues with the phone and Android 12 but so far I don't think any of them have to do with the install (of course I could be wrong).
Great! Thanks for the info.
Chiming in with a stock unrooted Pixel 5 using Nova Launcher. My Recents also becomes randomly unresponsive, and I am able to reproduce it using the method in the first post (press three times rapidly). I also get the weird zoomed out blank menu as others have mentioned fairly regularly.
So, a week or so ago I've been forced to install an OTA update (despite disabling these in settings, because see this thread), and now my navigation is screwed up.
Swiping right on the pill from any regular app correctly switches to the previous one. Doing the same on a home screen (tested with Nova 6 and Total launcher) *seems* to be doing the same, but in reality it enters a fullscreen version of "app carousel" that you normally enter swiping up on the pill.
The easiest way to spot it (and mostly how it screws me up) is that the next pill swipe right won't switch to the next app, but instead smoothly scroll over multiple of them. Another thing is that because it's the carousel and not actual app (despite being properly fullscreen), any iteraction enters the app, showing the fade-in animation. And only then you can normally use it, so it basically eats the first input you do. Except swipe up, which, like on the proper carousel, kills the app.
This DOES NOT happen with the stock Asus launcher, but I don't want to use it. It also was working well before the update, I swipe to get to the last back from home constantly.
In the attached video, you can see me demonstrating the problem:
- [00:01] First there's a regular "swipe pill up" to open the recents carousel, scrol it back and forth, start swiping up some app, this works as expected
- [00:06] Then, back on home screen, I swipe right on the pill directly, entering the bugged state despite it looking like if it just entered the Reddit app
- [00:08] But another swipe right, instead of swapping to the SCP Reader app, just scrolls thorugh a bunch of them
- [00:13] After swiping back to the first on the list, clicking a post makes a weird "pop-in" animation
- [00:15] Because now we're out of the bugged state and entered the app properly, only the next click selects a post like it should
- [00:17] Back home again, swipe right to enter bugged state like I usually get back to an app after unlocking the phone
- [00:19] Click to exit bugged state again
- [00:21] Swiping right on the pill *from an app*, which works as expected
- [00:22+] Swiping sideways on pill a few more times to show that it's *not* in the bugged state and changes one app at a time, also entering these properly right away
Does anyone also experience this? Obv I tried restarting the phone, disabling/enabling the pill and in general messing with as many settings as I could to try and poke it, but nothing still. It's SUPER disruptive in everyday use, I'd be very glad to try any suggestions/fixes.
This has been happening for last 3 updates if I recall correctly. I have switched to stock launcher until it's fixed.
Really sucks, A13 finally fixed issues with 3rd party launchers but after an update this issue appeared.
