Lineage OS : homescreen and menu buttons not working + black screen after reboot - ONE Q&A, Help & Troubleshooting

Am I alone ?!
Lineage OS works fine, for a couple of days, then, out of nowhere, the homescreen and menu buttons are not responsive. Then, upon reboot, homescreen turns black, showing nothing except the status bar. The status bar can be swiped down, but everything you click is not responsive.
Wiped Dalvik and cache, issue is still there...
* After a reboot, the device shut down inexplicably. Upon next reboot, issue resolved... WTF is going on?!

I have the exact same problem! Installed LOS on Friday evening and it worked great until Monday afternoon. Screen was on and had full notification bar contents - it looked like the phone was working properly. It could even take calls, receive emails and texts, but the rest of the screen was black and the buttons reset to original settings and didn't even work correctly. The Home button did nothing except a double tap would create a brief white border around the edge of the whole screen. A single press did nothing. The back button worked properly. The switcher button did nothing at all. I think it was doing the Google assistant thing. Holding in the power button was setup to press restart and then give restart options, but it was reset to just restart and confirm.
Restarting never worked to correct it. Wiped cache and Dalvik cache, still no go. Letting it sit for over 30 mins did let it recover once and one other time while driving it went from this black state to fully functional for no reason. It was good for a few minutes and then the buttons stopped working again. The soft buttons did not help either. They behaved badly as well.
It seems to have no pattern. I wiped the phone and flashed the newest LOS on Monday evening and it worked great until tonight. I have no idea what is going on!
Glad to know I am not the only one... Just need a permanent fix!

Nice, a brother !
The back button worked properly.

Same thing here.
Also, I can't tell if receiving calls work, cause I didn't try, but I can confirm the quick settings tiles keep working. The drop down notifications show up, but clicking an individual notification won't bring up the app it is refering to.
So far, the "shutdown, wait a little and reboot" seems like the only thing resolving the issue temporarely. So yeah, before wiping everything and reflash LineageOS, keep calm and wait !
Also, be sure to do a backup your working OPO/LineageOS phone in TWRP mode, so you don't waste time reflashing OS, restoring apps with Titanium Backup and restoring settings manually, like I did three times over the past two weeks...
Too bad we don't see the changelogs with each weekly LineageOS builds releasing or any bug report compilation.

I am conducting some trial and error testing to help isolate the problem. So far it feel like it is related to profiles, specifically with either a trigger or disabling the lock screen. It seems when I add a profile to unlock and disable my lock screen via a wifi "on connect" trigger, that is when things seem to go down hill. generally shortly after is when I get the black screen. I am using the Pixel launcher and have added a Home profile with triggers for wifi and then set my lock screen to disabled. I am currently using the default profile and have not added any others and the phone seems to work well with no issues. It is still too early to say that is the problem, or even exactly what the specific problem is, but I will continue with the default profiles as-is for the next few days or week to see if it remains stable.
Maybe this will help steer someone else to find a fix...

Also this has just happened to me.
All was working fine for a few days since flashed now have same issue as above
Also had Profiles set up for home network for lock screen and sync etc
Phone is Redmi Note Pro 3 though

Stumbled across this while looking for info on this issue
https://www.nico-maas.de/?p=1537

That link is going down the exact same path as I am. Coming to the same conclusions. Thanks for posting it.
With the default profiles in use, I no longer get the black screen and everything is working fine. I will need to keep an eye on the change logs to see if a profiles fix come down the pipe.

For me, it was changing the Lockscreen to none (from pin) that caused the black screen. That link defiantly helped me out. Only thing I did was edit the "profiles.xml" and changed '<screen-lock-mode>' to 0 instead of 2

Yep, also using System profiles to disable lockscreen at home or in car.
Lately, I get no issue at home, but only in car, where my system profile is also setup to activate hotspot when Bluetooth connected to my radio. As soon as hotspot turns off, issue is resolved.
On another side, I mentioned earlier that LineageOS doesn't list its changelogs. I was wrong. You can find them here : https://www.cmxlog.com/14.1/

Fixed!
I experienced the same problem today with my OnePlus 2. Guess time does heal. I waited for a good half an hour and it seemed to fix itself.
When the screen is off, hold down the power button for a second and you should see the power menu. Select 'restart' and let the phone reboot. Simple as that!
Tell me if the problem still persists.

Still having issues.
Notification cannot be seen , I can only hear them.
I haven't configured any profiles.
Home and recents don't work.
Can't open developer options, its says its not available for this user
Anyone have ideas ?

Help me
I got issues with LO, my back, home, recent buttons not working (capacitive) so I'm using on screen button. But after all happen, now I'm having problems with my volume button, it didn't work at all, already restarting my phone many times, also, chance the system profile to default, sadly, it didn't help. Can someone help me with it.

This is not a new issue. I first encountered on CyanogenMod 3 years ago, and I'm disappointed to find that it still hasn't been fixed in
Lineage os. In CyanogenMod disabling "reduce power consumption" in the adaptive display section resolved it. But now with lineage is there doesn't seem to be any specific setting that causes it.

had the same issue - pretty sure it has something to do with "Profiles" set up. For instance, I set up profiles for turning off Lockscreen when Home - using the WiFi detection.
After a restart, the screen went black, but funny enough, the quick menu and the Bar still showed up. I turned on Airplane mode, to switch to the default Profile - which enables the Lockscreen when not in wifi and restarted. That worked.
So I think something with the Lockscreen + Profiles is a bit buggy.
It only occurs after a reboot.
I am using LineAge OS for M7 14.1 - which runs great!

Have the same problem. Tried to update Lineage OS, but it didn't work out. Can anybody help me?

I solved this by clean flashing ( Data wipe + LOS Reflash ).
It's a Known LineageOS source bug ( according to their reddit )

I've started getting this as soon as I tried getting the first time setup to work again. Try this:
adb shell
su
pm enable com.google.android.setupwizard/com.google.android.setupwizard.SetupWizardActivity
2. adb shell settings put secure user_setup_complete 1
and if it doesn't work try adb shell settings put secure user_setup_complete 0

I have a Nexus 10 running the latest 7.1 Lineage image and had the same problem after updating the system and the GApps... here’s how I solved this problem on my tablet... maybe it will help someone else...
1) Use TWRP as your recovery loader
2) Backup your image using TWRP
3) Install the latest GApps - I use the Nano version
4) Wipe the Cache after the install is complete
5) Reboot and wait for the system to settle
6) Reboot into recovery (TWRP)
7) Install the latest Lineage (I use nighties)
8) Wipe the Cache after the install is complete
9) Reboot and wait until everything loads
10) Problem solved.
So... install GApps over the existing install... reboot let it do it's cleanup, then reboot into recovery and install the nightly update... wiping the cache of course... its worked for me three times now.

Great! Setting secure user_setup_complete to 1 seems to work for me.
EDIT: Nevermind, the problem only occurs when I connect to wifi with the screen off, which I didn't test. So no solution yet.

hello there! i have a similar bug on lineageos 15.
everything worked fine until today. no new apps installed or settings changed.
i flashed on 1. December and im really happy with this ROM, but today the hardware touch-keys stopped working correctly. The back button is ok, home button don´t work (except the double-tap function which starts splitscreen) and the menu button wich is set to swich last app with a single tap and show all open apps with a long tap opens the app-menu instead (that function that we know from android 4...).
after rebooting everything start to work again but only for a random period of time.
sry for errors or bad english...
i hope it will be patched cause the ROM is really one of the best i had.

[Q] Hyperdrive RLS14 Settings FCs adding Lockscreen Shortcuts

Cannot get the lock screen shortcuts to work with hyperdrive rom.
Noticed the issue, thought possibly got a bad flash. So I did another triple wipe/cache clear and installed the rom again. Still the same issue.
You can get as far as moving around the preset shortcuts, but when you try to click the (+) to add more the screen goes black before it pops up a message that settings has stopped. Tried rebooting the phone and adjusting several other related setting and nothing would change.
If there is a known work around like a cfg or something that keeps track of the lock screen short cuts that would do the trick.
Thanks

Known issue for Hyperdrive 14. It is being fixed for 15. In the mean time, start reading here: http://forum.xda-developers.com/showthread.php?t=2106830&highlight=lockscreen+shortcuts&page=462 for a way to fix it.
Thank you.
Let's hope I can figure this out.
Edit:
So I downloaded RLS13 and extracted the SecSettings.apk.
The question I have is do I simply overwrite the old one and reboot the phone, or should I zip the extracted file up and install it in TWRP?

Sometimes fails to boot/backlight kind of working - need technical help

Hey there, I have kind of trouble with my PQ.
The PQ sometimes fails to boot correctly.
Booting the PQ results in a short (a few seconds) backlight and then dark. (Important: No picture or text is shown!)
Then there are two errors I've experienced so far:
- after the backlight is dark, I press a button (POWER/VOL_UP-DOWN/CAMERA) and it vibrates. After a few times of pressing and vibrating, it vibrates long and it then seems to be off. Since the backlight is off, I can't know if it's really off.
- after the backlight is dark, I do nothing except sliding out the keyboard (backlight is off). In this error it seems to start "correctly", because after some time the keyboard backlight goes on. That means, that "android" has bootet and is waiting for password entry (because of encrypted phone).
Either way, I have to reboot several times until it boots correctly. (With some luck it takes only 2-3 times.)
Some notes:
- I have to put my sdcard off, because the password entry doesn't appear if it's in. (ext4 filesystem, android seems to want to decrypt that -.-)
- [needs more testing] The phone has had force resets. I think it was my Access Point/Router, causing the WLAN (or qualcomm SoC) to hang. I changed the screen-part (touchscreen+display etc.), seems not to help. (I also disabled that Access Point/router, so I'm still waiting for a force reset.)
- [needs more testing] Sometimes the SIM-card and/or sdcard is not recognized after a reboot/cold boot. I have to reboot to get it back to work. SIM-card recognition may take more than one reboot.
What's in /system?
- CM11 M11 snapshot
- gapps
- XPosed framework (it boots and everything actually works fine)
...if I forgot anything, I will notice that in a later post or edit this and notice in a new post.
I also have a problem with wakeups again (started just a few days ago, after uninstalling two apps...). That's weird, but I can't find the cause. Neither in the XPosed Logs nor in catlog. I need to investigate it further.
I tried to be very exact and I've put anything that might be relevant into this post.
If you have any ideas (no matter how implausibly they are), post them. I am out of any ideas.
It might be helpful to get a log when it boots "incorrect", but I'm sure it's not written anywhere inside the system.
The good thing is, my wakelock problem "disappeared".
The PQ is having deep sleep again.
I have no idea what the wakelock caused...
No force reboot so far.
Another good thing: the force reboots are gone after disabling the AP/router which probably was the cause.
A stable week for me, the phone didn't crash at all.
Of course the other issues stays.
Saturdays (today) the phone is being rebooted by Titanium Backup. Like a wonder, the phone chose to show the password input (encrypted phone; with sdcard inserted).
After entering the password and some boot-time, the mobile part (SIM-card etc.) chose not to work.
A reboot didn't help and I've got into the annoying problem, that I get a blank black screen with backlight but it boots "normally" (without anything displayed).
It took about 20-30 minutes with trial and error on getting it up with the mobile part again.
BUT: I've found today something new, beside the issue this morning.
Bluetooth seems to be enabled always! It's probably caused by Llama (android app).
Needs also further testing, just wanted to write that somewhere down, so I don't forget.
More details: After disabling it, my "PS3 headset" wanted to pair with "all" devices nearby.
I got pairing messages on the PQ even with disabled BT.

(If anyone cares) the force reboots are gone after setting preamble to "long" (PQ malfunctioning if set to "short") in the router.
The other problem persists but are not that bad because it happens rarely that I need to reboot (soft reboot is mostly enough).

Old Samsung i9100 Cyanogenmod reinstall/upgrade

I have a Samsung Galaxy S2 (i9100) with the latest Cyanogenmod v11 (Android v4.4.4). A few days ago when I turned it on, I found it had gone silly and lost many applications and settings. I re-run link2sd, thinking it might be the problem, and I did manage to get the apps back. However, it seems that some system settings are lost for good, and there are a few glitches:
- The home key doesn't work in the system UI Trebuchet. No home screen, no process list with long press, etc. The button itself works ok, since it gives vibration as feedback.
- The lock screen security never kicks in, so when the phone goes to sleep it's unlocked, even if I set security to "Pattern" in Settings -> Lock Screen -> Security.
- Some other settings don't work, even if they appear to be set correctly and I keep on confirming them. For example: The notification drawer has disappeared and won't come back again. Some kind of icons won't show up in the notification bar: WhatsApp, SMS etc. There's no extended power button menu even if it's enabled in my preferences.
I thought I'd solve these problems by reinstalling Cyanogenmod 11. I have a few questions.
Can I reinstall the same Cyanogenmod version without a hard reset? Any important piece of advice about that?
Can I switch to Cyanogenmod 12 flawlessly? I am afraid about doing that because I don't want to lose my working recovery. I have CWM-based recovery 6.0.5.1 right now, and I wonder if it's compatible with CWM 12.

Recents and home buttons stopped working and no notifications appear - any ideas?

Very strange one... My wife's VZW Pixel (I have one too) suddenly experience a bunch of changes that we can't find the trigger for. I just spent a hour troubleshooting every possible thing and I am stumped...hoping for some guidance.
Known facts
1. She changed nothing
2. At least one app (siwftkey) auto-updated... I uninstalled it but that didn't fix it
3. She was on the December patch when this happened. I updated to Jan but that did nothing.
4. Device is stock, unrooted with Nova launcher (I tried the pixel launcher and the same issues appear)
Symptoms:
1. Home and recents buttons do not work on any screen... Back button still works
2. No notifications appear on the NAV bar and nothing appears when you swipe down. Sound notifications do work however. No apps are blocking notifications and the individual app notifications are set up properly
3. Double press the power button no longer goes to camera even though that gesture is toggled on
Factory reset is my next step but I am traveling right now and she will need me to set everything back up so I am hoping there might be a fix short of a full reset.
And suggestions greatly appreciated.

Last resort, you can backup apps and data using Helium, then factory reset it. Then restore with Helium. To use Helium, you'll need a PC though.
Any other results on this?? My pixel just hit the same problem! It is in an area that has no internet so it is causing all sorts of issues. I don't know if the two are related at all.

Unfortunately not... Did a factory reset and that cured it. Not one issue since then. Must have been so random app she downloaded that created a conflict.

Happens with me today. I was messing around with the device and when I clicked in a YouTube video link on notification shade the device suddenly soft reboot.
Since them, home and recentes buttons won't perform their actions. They still vibrate and home button animates on touch. Status bar shows none notification, even I knowing they are arriving via notification sound and quick settings shade won't pull down completely. My tiles was rearranged as well. No mobile connection either.
I'm running lattes official Oreo. Never unlocked and never rooted my pixel XL 128.
For me a factory reset through settings did the trick.
Would be very good if Google could light us about this issue. No rouge apps on my device. In fact I'm using a few
his is an Android issue.
Step instructions:
- Download Nova Launcher. If you cannot from the google play store, search for it on Chrome and download an apk version
- Install it (you may get a pop up advising you need to let apps installed from chrome, go to settings and allow it)
- Once installed, click on Open. This should launch the Nova Launcher
- Long press anywhere on the screen
- Choose Widgets.
- Look for the Activities widget and hold and place it anywhere on the screen.
- Scroll down to Setup Wizard. There's two, one that's "Setup Wizard" and the other "SetupWizard" without a space. Choose the first. There should be an option under it called ".SetupWizardUpgradeActivity". It might be slightly different for you pending the version OS you have but that's what came up for me.
- Select that to create the widget shortcut then click to open.
- This will bring you to the setup wizard and then just click Next all the way through (turn off any preferences you may have in the past)
You can uninstall Nova Launcher afterwards if you want. You don't need to set it as default.
Perfect!!! Thanks.

Some very annoying issues with OP6

Iv'e been having these issues for a few weeks now, maybe someone else had them too and can help with these...
1. There's a huge lag with the share menu on every app except for Google Photos. It takes about a minute to open and until it does the app just freezes. happens in Gallery, Facebook, Whatsapp and everywhere else.
2. There's also a huge lag when an app is trying to open another app. For example, if i click on a Youtube link in FB it would take about a minute to actually open the Youtube app. I tried changing the defaults in the settings but still nothing.
3. When i go to Settings, if i go to "Apps and Notifications", it takes about a minute for the menu to open. Once it does everything works ok but if i go into a certain app settings, and i hit "back" and it's supposed to go to the main apps menu, it lags again.
4. 90% of the time to "press power twice for camera" shortcut does not work. When i do it the phone vibrates like it always does but the Camera app doesn't open.
I am on 9.0.5, Magisk 19.1, XXX No Limits.
Things i tried:
- Reflashing the rom
- Uninstalling XXX and Magisk
- Wiping Cache in recovery
These didn't help much. I tried going to OB but i still had the problems so i went back to stable which wiped everything clean and solved the issues... until a few days later when they started again.
If anyone has any other suggestions, i would be happy to hear it. Thanks in advance!
If you did a clean flash and it reappeared, it's probably a rogue app. Do another and restore things one at a time until the problem recurs.
I'm also experiencing few bugs ever since switching to 905 on both slots, mostly WiFi issues and WhatsApp being very delaying with messages etc.
had the same setup as you thought I'll go use custom roms and it's the same on those, so I'm guessing it's 905 oos the bad Apple here
I confirm delay on Whatsup....
Can i revert to 9.0.3?
Did you try a Flash all by Fastboot?
You should have stayed with Oreo
