[Q] Screen black after screen unlock

I've noticed that sometimes when I unlock my device I have a black screen with only the "multi-task" button and the status bar visible. It will stay like this until I "lock" the phone and unlock it again. Touching the "multi-task" button makes the rest of the buttons appear but touching them still doesn't make the screen respond. I have noticed this on both stock and custom rom. Has anyone else had this problem? Any ideas on a fix or cause?
I am using the Virgin/Bell Canada GSM version.
Thanks
ps. I've posted a pic to give people an idea of what I'm getting....as it may seem unclear in my explanation.

At first this sounded similar to a problem I had.. I installed Wave Launcher, which for some reason did not play well with my phone. I would unlock the screen and the screen would immediately go black as if it had shut off, but I could still push buttons and receive haptic feedback. I had to have someone call me and delete the app while I was in the call.. it sounds kind of similar but not really.. my first guess would be some sort of problem with an app being incompatible.

I wanted to pass this on...I was reading in the Team Kang rom that there is a "bugfix version: app navigation menu icons no longer disappear after unlocking phone". So I hope this is what relates to my problem and has been "fixed"!

Sorting facebook posts

I've got a strange problem with the Facebook app on my GNEX. Everyone I know has a button in the top right corner of the screen to choose either Most Recent Posts or Top Stories whereas I have a button which takes me to Find Friends. Anyone else have this or know how I can get the sort button please?

Same issue here, and its driving me nuts. I have version 1.9.8. my GF has the same version. Shes got the sort button and I've got the stupid search friends button. Im also missing the sync contacts option in settings that she has. Any Ideas?

I figured it out!!! The automatic time setting was turned off on my phone and the time was a few min behind. Changed that and Fbook was back to its usual self.

Multi-window buttons disappeared

Hello people,
I'm a long time lurker and first time poster
I got my GN2 a few days ago and absolutely love it. The only problem is that when I use the multi-window function, I don't see the "fullscreen" and "switch screen" buttons anymore. They were there when I got it, but they somehow disappeared.
I checked all the settings, but I can't seem to find a way to re#enable them.
I feel kinda noobish.
Anyone had the same problem?
Thanks in advance,
TG

I'm guessing you are tapping on that bar in the middle to make that button appear?

Hi folks, holding down the back button seems to make the multiwindow tab reappear. ..hope that works for you

The switch and full screen options appear whenever you resize the windows. Try moving the bar in the middle up or down and they would appear.

It didn't work before doing any of the above...
Now I just flashed a new firmware and everything is well
Thanks for the hints though

hold the back key will show/hide the multi- screen

Thank you very much for the hint.
i found out after your hint that holding the back key will show/hide the multi-screen option. so you can see the small blue button on the left side of your screen.

Damn. .. gone are the days people used to read the manual

[Q] Viperrom Stuck in full screen mode -Status bar and bottom hide until I swipe

Stuck in full screen mode -
The Status bar and bottom bar auto hide. until I swipe to bring them back. How do I disable? On viper rom.

Wrong place to post. There is a thread for ViperROM believe it or not.

I wasn't certain it was because of viper rom, as I can find no relevant setting in Venom tweaks to fix this. Is there a core Android setting for this? I've searched extensively and found nothing.

I believe this is in the right forum now.
any ideas?

ok well... strange that my android started going full screen on viperrom suddenly and no one knows how to change it back. guess it's time to wipe and start over.

I know this is kind of an old thread, but I just had the same problem. I think I put it in fullscreen mode while it was in my pocket and couldn't figure out what was going on for about 2 hours. For anyone else that encounters the same situation, here's the solution:
Press and the power button. At the bottom of the "Phone options" window that pops up is the Fullscreen mode option.
Also found that when I take it out of fullscreen mode, I have to reboot it to get the Status Bar to stop auto-hiding.

Thanks
you're a life saver,
i dont know i missed that out, i rebooted the phone a dozen times and scoured the venom tweak settings for hours to no avail
thaks again

buddy_lee - You're awesome. Thank you. I'd been dealing with this for a few weeks and it was driving me insane. I"ve looked through every setting on the phone, viper, and nova and couldn't figure it out. Can't believe how simple it actually was.
THANK YOU

Thank you so much!! I was crazy because cannot find out why my navigation bar auto hide, for about 2 hours. You are my hero.
I just register as a new member for comment and thank you for your help buddy_lee

Home button continues pressing?

I've had this issue before on my LG Power (Straight Talk branded LG Leon), running on Lollipop 5.0. No matter what I look for I can't find anyone who's experienced similar issues.
It just happened last night on my 5-day old Nexus. I could not open any of my folders to access apps. As soon as a touched a folder, it briefly showed the animation to open it, and it immediately closed. Whenever I selected a widget or the app drawer, they would immediately close as well. When I attempted to swipe down the notification/quick settings shade, they immediately closed themselves. Turning off the screen resulted in the screen immediately turning back on, albeit locked. I was even having trouble turning the device off because the 'Power Off' menu would disappear right after it popped up. Eventually I was able to time it right and was able to power off. Since I restarted I have not have any issues.
Any idea what gives? I'm unrooted, locked bootloader, everything 100% stock, running MM 6.0.1.

the only explanations i can come up with are:
-accidental touching the area in some way (unlikely)
-getting some substance stuck on the screen in that area (unlikely)
-a faulty touch panel (unlikely and very specific defect)
-a hickup in the software (again unlikely)
then again, if the OS (for whatever reason) thinks the home button is pressed, on default it should not only pull you back to the homescreen, but continue and send you right through to google. the conclusion of which would be, that this UI area is triggered repeatedly rather than continuously.
keep an eye out for what could have triggered it in case it occurs again.
check your settings what build exactly you are running (settings -> about phone -> build number).
ans lastly, if it happens again, you should still be able to hold your power button to hard-reboot it (no further interaction with the UI required).

Try to clean your screen also with a towel

That is extremely weird. It really sounds like a faulty digitizer, but you'd be the first... Maybe it's a rogue app, but unlikely.
Were you doing something before this starts to happen?

I haven't noticed any consistent apps or behaviors when this would occur. This most recent time, I was low on battery (10%) and I had just flipped on my data.

fyi. you could also just press and hold the power button, for 10 secs, for a reboot ( might come in handy when the screen isn't working properly).

appreciate the tip! I'll keep this in mind if it happens again.

Finally was able to capture a video. The issue occurred after I was playing around with Open Camera and it crashed. Holding down the power button didn't work when this glitch is happening.

What's the icon on the lock screen, top right in the status bar? That behavior is unusual if it's not a screen defect. Are you using any apps that monitor battery, a task killer, or maybe a security monitor app?

The icon is a picture for my user profile on the phone.
I don't use anything like that. I had Clean Master installed briefly but it's been uninstalled for a couple of days now.

so it seems like this issue pops up whenever the camera crashes. happens occasionally when using the camera shortcut (double power tap) or in an app that uses the camera.

It's got to be software IMO. It didn't happen when you went to Google Now and your Recent Apps. I'd try uninstalling the Open Camera app first. Do you have Face Unlock active by chance? After that I'd FDR...

right, that's what's confusing me. i did a factory reset last week, set up the phone as a new device. haven't installed a new camera app, just the stock google camera. the issue occurred again last night when using an app called Shopkick, which accesses the camera but crashed.
