Screen white unresponsive phone - Galaxy S II Q&A, Help & Troubleshooting

I was on my phone using xprivacy and blocking Facebook permissions when I noticed my entire screen was this weird grey colour even the status bar it was all one colour the text hadn't changed though just the background, there were dots of red/ purple on it as well, then the screen just started getting whiter and brighter and lots of lines going across the screen appeared, I tried pushing any of the buttons but nothing happened so I pulled the battery and then rebooted the phone and everything appears fine. If anyone can tell my why this happened, if it'll happen again and if there is anything I can do about it I'll be very grateful
Thanks in advance
PS sorry if this has already been asked I don't have access to a PC for the next few days so I couldn't search

You're not the only one experiencing this.It used to happen on my s2 once in a while and i had to reboot it by taking out the battery.It happens on my nexus 4 as well,except that it reboots itself.I think its related to custom ROM/kernel being installed.Just a software glitch.

OK thanks do you know what could've caused this? (I mean obviously apart from custom ROM/kernel being installed anything you do on the phone or is it just random)

None of the root apps I had installed on the s2 are on the nexus4..nothing in particular.not that I remember of.

Yellow line in lock screen

Hi All,
I have been using my galaxy s2 since last 1.5 months. No issues/errors/defects till today.
Today all of sudden a yellow line appeared in my lock screen. It is horizontal line coming between date and time. This line only appears in lock screen once I unclock my phone then line is not there which means it is not hardware problem. Please see the following pics with line and without line.
Guys, could you please help me how can I remove this line.
Thanks,
JM
have it too. disable the screen lock, then it must gone.

I think it's normal
Maybe you haven't noticed before?

No it wasn't there earlier...

are u sure? i think it was always there, but it could be that you had a darker background for the lockscreen
I'd like to inform those reading this post that I just experienced the same problem as the OP. No way to get rid of the thin line which wasn't there before. Corrupt lock screen wallpaper? I don't think so, since changing the wallpaper doesn't solve the problem. Also it can't be a hardware problem since the thin line appears on the lock screen only. I now notice this line on all types of screen locks (pattern, pin, password).
Hope this helps
It's just a line across the screen. It's part of the lock screen.

I dont have that on my lock screen, can you set the same image as a homescreen wallpaper and see if it also has the same issue? I've got a feeling its a defect or at least a SW issue.
Root your phone and buy widgetlocker....

It is not a defect. My phone does exactly the same. Maybe some FW has it and others don't, but it is not a problem. It is just part of the design of the lockscreen.
Obviously it isn't a hardware defect, since it clearly appears on the pics you posted, and those are not photographs.
It is also precisely in the middle position between the date and the alarm indication, therefore I'm pretty sure it's there on purpose, software coded.
Just a question: are you using the stock firmware / ROM / launcher??? I'm on stock firmware, ROM and launcher and yy lockscreen is far simpler... I just have the digital time and date overimpressed on the lockscreen picture, and nothing else.
I am having this problem as well, though my line is grey. The horizontal line goes from one side of the screen to the other between the date and the alarm time. This line was NOT there an hour ago so we can dismiss any answers like "maybe you just didn't notice it". The only change was that I powered down my phone and powered it on again. I, like most, originally thought I had a problem with my screen but it only appears on the lock screen. I normally use a pattern lock but I checked and the line appears when it is on number lock as well. My wife has never used the lock feature but I set one up just to see and she has this line as well. It doesn't serve a purpose and it wasn't there before, I'd just like to know why it is now. Can anyone shed some light on this? Thanks in advance.
If You setup PIN lockscreen and then go again to lockscreen settings phone asks You for your PIN before allowing to change settings. This line is there also. It's not a "problem" or a "defect" it's just a part of the lockscreen design. You act like it's some kind of a disaster and huge bug which renders phone unusable but it's just a line separating date from time seen for about 1s when unlocking screen. Do You think there should be a switch do disable every part of android interface ?
Ps. to be sure - I rebooted my phone and this line is there also just after reboot. And this line is not grey - it's semi transparent. I'm certain that in my case it was there from the beginning.
Ps2. look at this or this one - returned by google images for "sgs2 symbol lockscreen" - nasty lines everywhere
If You hate this line soo bad try to prepare wallpaper that has it's own line at this position which when merged with this semi transparent line will become invisible.
This has appeared in mine today. I've also noticed sometimes that the lock screen touch screen messes up occasionally and when you drag between the lock dots to do the pattern; it drops the line drawing after a dot when you change direction.
If I turn off the screen and light it up again then once or twice it fixes the drawing problem, though the horizontal line is still there.
Has anyone on this thread experienced degradation of anything on their phone since they noticed this lock screen line? Want to catch a fault before my warranty runs out (if there is a fault!)

Status bar notification pulldown not working CM7

Hi, on the last 2 days my phone started acting crazy, screen became unresponsive and the phone became slow. I rebooted several times and the screen became responsive again, but not as sensible. The top status bar drop down menu is not working even after several restarts, I cannot click on the top and drag the notifications down. Is there a software that covers this particular feature, or should I flash an updated ROM like CM7.2? Thanks.

I'd try just clearing cache and dalvik and reflash CM7.2 as a first step. I had a similar situation last week, things just acting weird and sluggish, and a reflash worked.
It was a dying digitizer... got rid of that unit and got a new desire HD.

My S2 Screen gets inversed color sometimes

Sometimes, my phone gets inversed (black -> white, white -> black and the same with other colors). Is there anybody get this problem too?
I saw that some HD2 users get this problem too (http://forum.xda-developers.com/showthread.php?t=942403) but no solution yet. It gets normal back after a reboot but then it comes again. I have met this problem 3 times for 3 months since the day I got this phone.
Is there anyone know what happpens? Screenshot shows a normal screen.

What kernel are you running? I need more information about your device to be able to help.

If you are using a custom ROM or custom Kernel it could be mDNle toggle.....
Does it happen if you press the home button quickly 4 times? Mine does this as I am running the Siyah Kernel and it has this option.
Try pressing the home button repeatedly quickly and test.
If you're using a stock ROM and Kernel then I'm not too sure, could be a screen problem or just a simple glitch that a reflash or factory reset could fix.

Top Screen touch not working well when battery low

Hmmmm, not sure why but sometimes when my battery is low, some parts of the top of the screen tend to stop registering touch input. As an example, if i'm in the Play Store and I try to touch the search bar to bring up the keyboard but it doesn't work...also sliding down from top to bring down notifications also doesnt work.
Anybody else have this issue?
nope
I've never had the screen stop registering touches, but I often have the notification bar stop responding to swipes.
I can resolve the latter by going to the lock screen and trying it there. The notifications will always open from there, and it starts working after being done once.
I've also set up a gesture shortcut to open the notifications by swiping down with two fingers. I'm using Nova Launcher, and that one always works.

I also am using Nova and have had prime installed for a long time.
I also had this issue (though at 100% battery) after a reboot. Rebooting again didn't work. Switched to TouchWiz briefly which also didn't work, but then I hit the Nova Prime button (already installed) and after reverting to Nova Launcher it started working again. Not sure exactly what fixed it though.
I think I'll send a link to the Nova dev and see what he thinks
delete
I sent en email to the devs with a link to the thread. Maybe they will find the cause of the problem
I restored my phone 2 times in the past week and problem randomly comes back. I don't even have to have a low battery, it did it to me 10 minutes after taking it off the charger for a full night. I have no idea what is the cause but about 1/2 inch of the entire top of my screen has no response to touch. I can solve this by rebooting but recently i discovered that if i flip my phone and force it to rotate the screen, the problem stops right away. I doubt its a hardware issue, but then again, if it was software, a restore should have solved that issue.
This is happening to me as well and I'm using Apex, not Nova. Seems like it's been randomly happening since 5.1.1 was installed. Any word yet on a fix?

Swift 2 + screen burn?

Having a bit of a problem since yesterday, all of a sudden the colours on my Swift 2+ have gone really, really dark and on the lock screen I can see shadows/burnt images of the status bar and nav bar almost like overlapping my screen? I thought maybe it was something to do with a theme I installed, so I uninstalled all of them to no avail, so then I thought I'd do a factory reset on my device, still hasn't fixed it... Is this to do with the hardware itself or is it a software issue? Thank you in advance for any help
That happened to me a few times on my swift 2+ but it went away after I restarted the device and it hasn't happened to me since I updated it to the latest software. Also, I think the faded nav bar is something that's part of the software and not screen burn because it's not there when the device is turning on or when it's in the bootloader

Had a similar problem twice recently but by rebooting that got rid of the problem.
