[Q] Screen black after screen unlock - Samsung Galaxy Nexus

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"!

HTC Phone Lock (Transparent)

Hi All,
Does anyone know how to get this working on our beloved HD's? I hate the way the screen goes completely black during a call, we can't use the light sensor to tell the phone that the call has finished and it is away from your ear (so screen comes back on a la iphone), and i keep doing things during a call with my ear!!
So this seems like the ideal solution - but i can't get it to work!!
I've copied over the file to the windows folder, then soft reset. Changed the registry entry for phoneLockEnable to 1 in HKLM/Software/HTC/Phone but still no joy!
All help would be greatly appreciated.

Beside this transparent canvas, where can I get the orginal canvas?
I am using a offical ROM but I don't see this function!

that's interesting, because my screen doesn't go blank during calls and it happens quite often that i accidently disconnect a call (i suppose because i hit a button with my ear).
so in search for i solution i found in Advanced config a tab Light sensor > Light sensor polling which i set enabled. the explanation says "uses light sensor to automatically turn screen off when the phone come near from your ear to answer a call". so this should set it like the i-phone does, right?
hence when i tested it, the screen still was on, even when i put my thumb onto the light-sensor.
is this because i don't have a stock rom (i use Duttys HD V1.9b XTREME) or is there something i can do about it.
it would be really nice to have the screen locked when i answer a call and to outomatically unlock it if i remove it from my head to use some function on the screen..

Hi take55,
Yes, i'm aware of the advanced config tweak (also in HD Tweak), and as you correctly state, the screen should/will go blank on call connection (i'm running kwbr's A Touch Of HD 3.3.4 and mine doesn't, even with tweak applied!!).
Unfortunately, when the call ends and you move the phone away from your ear, the screen still stays blank????? I've read somewhere on these forums that it never will work like the iphone (not sure why, as the light sensor should recognise that we've moved the phone away from our ears).
So that is why i'm trying to get this other method to work. What i have noticed is that with the bmp copied over to the windows folder or with a cab i found by A-Math installed, my dialler locks up after every call (as if the transparent phone lock is in place) but i can't actually see it. None of the screen works and i have to soft reset. Maybe something is stopping the bmp to show on the phone....who knows.
It also might be the fact that this was designed for the Diamond (found the cab on the Diamond forums).
Just hoping some genius here might now how to sort this.
I've attached the cab file i've found, give it a try and see if you have the same issue as me.

DF

It has nothing to do with the BMPs but with the registry setting that the CAB also makes. It sets HKLM\Software\HTC\Phone\PhoneLockEnable to 1, in wich case you'll have to press the power button to unock (no need to soft reset). For the BMP to work the phone/dialer software will have to support it, otherwise it just locks the phone in the usual way: black screen, power button to unlock.

tks but your cab only for the canvas skin only, do not contain the original software (slidable canvas), anyway, tks for your help
I've also found this problem to be quite annoying during a phone call but have found some sort of way to deal with it.
Firstly my ROM isn't tweaked, its just the basic one already installed.
After a call is connected, the screen switches off. But if you need to access the screen again during a call, I just press the "Back Arrow" key, one of the four hard buttons on the bottom which brings the screen back up again.
If you press the phone button instead whilst the screen is off, the screen lights up again but it puts the call on hold.
This probably isn't the best way to deal with this, but it seems to work for me for the time being, hope this helps anyone else here.

Useful info - I found this particularly annoying yesterday during a ouple of calls.
Also discovered Gyrator tries to turn the phone screen and was laggy - which was even more annoying!
Everyone!!!
CHECK THIS OUT - http://forum.xda-developers.com/showthread.php?t=489034
Answer to all our prayers - a screen lock which uses the g-sensor and not the light sensor.
Now, when a call is connected, holding the phone to the ear blacks the screen, but when you bring the phone down (to use the keypad or something), THE SCREEN COMES BACK ON!!!!!!!
Tried and tested on kwbr's A Touch Of HD v3.3.4 (probably the best manila2 ROM out there!)

[Q] Unintentionally rejecting a call

Hi,
Sometimes, when my DHD is in my pocket and it rings, I take it out of my pocket and, Unintentionally, rejecting the call (it seems that I am touching the screen).
Any idea how to stop it from happen?
Hi, I use Call Confirm App as I used to have the same problem, thankfully not anymore now.
What is the name of the apps?
Thanks
Call Confirm App
I installed it but it is good only for outgoing calls.
I need an app for incoming calls.
Oops sorry about that still haven't got rid of my hangover yet.
Only other thing I can suggest is get a leather-ish flip case.
I use one I got off the "bay" and it does the job OK.
Del.
Thanks.
No app?
I have exactly the same problem.
If you like, you can check my theme here: http://forum.xda-developers.com/showthread.php?t=911474 and especially its last post... but I havent found any "full" solution yet.
I have the same problem too.. :/ The only solution so far is to pull it out from the pocket very carefully without touching the screen. That just annoys the hell out of me.
I believe this will solve your problem. It's in the market and it allows you to delay button presses, to prevent accidental rejections. Check it out.

you have several options, but unfortunely none of them are great! =oP
this "slide" is a part of htc framework, so it can't be changed (if you wanna stay with sense)
so, when i'm with sense i prefer widget locker, it's a really great app, "solve" this problem by put a unlock screen over the original one (so, you pick out the pocket, unlock the phone/widget locker, see who is calling and slide up/down to answer/deny, basicaly you need to unlock you phone twice)
other idea is simply disable the lock screen and use widget locker to unlock the phone, the idea is:
- Disabling lockscreen you will get a incoming call with no slider, it will be replaced by that simple two buttons "answer" and "decline" (the same you got when the phone rings and you are using it)
- when lockscreen is disabled, the screen goes off, but any key turn it on again, so, you use widget locker to solve it, and let the option "over the original answer/deny call" ticked (but it won't stay over anything, because lockscreen is disabled)
you can also try http://www.appbrain.com/app/proximity-screen-off/com.itsme4ucz.screenoff
that app has a option that let your phone with screen off when it is in your pocket, using proximity sensor.

my screen goes blank.. but the call is still pending sometimes.

Lock Screen every time I switch apps from notification menu

I did a quick search but didn't find anything on this. For whatever reason, whenever I switch apps from the drop down notification menu, it forces me to input my lock screen pattern, even when I have the lock screen toggled off. I have my settings set to auto lock after 1 min, but this happens whenever I switch apps, even before a minute has passed.
Is this a known issue? Is this happening to anybody else? Is there a fix?
Thanks.
Edit: I'm still on 4.02. It hasn't updated to .04 yet.
No one?
:T
Has this always been happening or did you install/flash something before it started happening?
Sent from my Galaxy Nexus using XDA
I just got my GN yesterday, and it updated by itself to 4.02.
It's been happening ever since I turned on the lock screen. It goes away when the lock screen is turned off. But it's bizarre that it would ask for the lock pattern every time I switch apps from the notification drop down. It doesn't ask for the pattern if I were to switch apps with the App Switcher button.
Really perplexing...
Hate to keep bumping this, but this is just incredibly bizarre.
Can someone test on their GN if the same happens? Turn on a lock screen input, anyone will do. I happen to have the pattern lock. And try to switch between apps or alerts from the pull down notification menu (you can send yourself an email or something, or turn on the music player) and see if you are forced to put in your pattern/passcode/etc before you can switch over.
I have to put in my pattern to unlock the phone every single time I switch apps ONLY from the pull down menu. It's bizarre. If I switch apps from the App Menu, it doesn't do this.
I don't know what's going on. Is this a "feature" of ICS? Seems a bit overkill on security. Or do I actually have a faulty phone (but it seems software related?).
Any help would be great. If need be, I'll make a video to demonstrate what I'm talking about.
I had this problem on CyanogenMod. Change the lock screen to what you want, and then reboot. It should be fixed. If you don't do a reboot for some reason it gets confused.
Yes happens to me sometimes too on both 4.02 and 4.04 stock. I don't use a pattern lock but it just fades out and when I turn screen back on it's lockscreen.
Never had this problem. That is weird. I suggest flashing a stock image and see if it still happens. Make a nandroid first of course but throw it away and make a new nandroid if problem goes away.
bow chicka wow wow.

Yes, this solved it. Thank you! Oh, Ice Cream Sandwich.
I spoke too soon. It's back. I noticed when I toggle the lock screen off, the problem exists. But if I toggle the lock screen on, the problem goes away.
So it may be an issue with the widget itself. I'm using "No Lock" (https://play.google.com/store/apps/details?id=org.jraf.android.nolock&hl=en)
I'm gonna test other toggle widgets to see if it's app related.

So.. it's a third party app you're using and not the stock ics lockscreen..
It would've been wise if you told us that on the first post

Yes that would have been good info to have, but I am not running anything custom on my lock screen (though I am on CM) and had this same problem.
I had to reboot the phone after every time I changed the lock screen from anything to anything or I'd run into problems. When changing from no lock screen to a lock screen, I would lose notifications when waking the screen up if the notification was for the last app open.
For example, I was in the Messaging app and locked the screen, without going to the home screen first (so if I were to unlock the app would be right there). Then I received a text and notification worked. I pressed the button to wake the phone and the lock screen showed up (pattern unlock) and the notification for my new text message in the notification bar disappeared. But I hadn't even unlocked so I could get to the app yet...

[Q] Screen Won't Unlock

I am running the stock ROM, only rooted.
Sometimes when I try to unlock my phone, it acts as if I'm not even trying to unlock it in the sense that it doesn't even respond when I drag my finger across the screen. The only way to unlock it when this happens is to touch and drag an icon and unlock the screen that way (IE - open an app from the lock screen). I can then re-lock the screen and it will behave the same way again by not unlocking as if I'm not even touching the screen. The only way I have found to solve this where the lock screen reacts normally again is to reboot the phone.
The strange part about this is that in the developer options I enabled the show touches option thinking the digitizer just wasn't responding for some reason, yet I can see that touching the screen IS in fact working because it sees all the touch inputs. It just won't unlock. I can press the back arrow so it highlights the box I'm supposed to unlock inside and it still doesn't work. I just don't get it. It has done this since new as far as I can remember.
Anyone else?

I've got a similar issue, except mine is intermittent. Twice I've had the lock screen freeze on me. The only way to unlock it was to pull down my notification screen, set up a pattern for unlock, and then use that. Then I switched it back to swipe to unlock and it worked fine. I'm watching it carefully. If it starts happening more often, I'm going to request a warranty replacement.
Well, mine is intermittent as well. It doesn't happen every time by any means, just sometimes. As I said, I can pull it out of my pocket every once in a while and it does it. Do you have icons to launch apps from the lock screen? You should try that and see if it unlocks for you like it does for me.
I'm having the same issue. What ROM are you guys on?
This is still occurring and very annoying. I just got a second S4 as a work phone and it has not had this issue yet. As I said, it happened with the stock ROM, but currently I am using THIS rom. Happened again twice today.
Yea that happened to me to but since I rooted it and installed wicked v5 it's never done it again

This has to be an issue with the T-Mobile ROM, I am surprised I haven't seen other posts about it. I wonder if it's because most people have some kind of security on them and I only have the swipe to unlock with no effect? In any case, my work Verizon S4 has yet to do this, whereas my T-Mobile S4 does it at least once every couple of days.
The same thing happens to me as well. I got really frustrated, so instead to swipe to unlock I now have pattern.

Screen Unresponsive After Unlock

So, I have a G4 for about 3 months and lately I have noticed a bug of shorts. I recently started using pattern as my default unlock method and I notice sometimes (once a day or less) that when I unlock the phone everything is unresponsive, and I mean everything. It's like its frozen. If I press the power button and unlock again everything is functional like it never happened. Anyone has any idea why it's happening? When I didn't have a lock screen I had never seen this happen so I am guessing it has to do something with the lock screen. If so, if someone has any idea how to fix this it would be appreciated. It's not like its a major issue however it is kind of embarrassing for such a high end smartphone to have problems like this one. Now that I think about there was one time that this happened while sending an instant message by facebook messenger but I don't think it is related. Maybe the app did mess the system there somehow.
I know this post is old, but I have the exact same issue on my LG G4 Verizon. Upon unlocking with the pattern, every so often the screen is unresponsive. I can still change the volume with the buttons and the slider pops up to display the change like normal. I too have to re-lock and unlock the phone to get it to be responsive again.
