Strange issue on Android Lollipop - Android Q&A, Help & Troubleshooting

I have a cheap LYF phone which has a strange issue. When I switch on the phone and try to open the lock screen - it flickers to the wallpaper, then goes blank and couple of seconds later relocks the screen. And it repeats the cycle over and over again, automatically. Screen turns on, it goes to the app drawer, screen flickers, goes blank and relocks the screen.
Even the top half of the screen which shows network connectivity flickers between showing no sim, then no connectivity, back to no sim. It is also losing battery at a rapid rate because of these changes. It doesn't even charge when the phone is on. Charging while the phone is switched off works fine.
I made a video about it, apologies for the huge background noise:

I think it's a problem of your phone's system ui.

Current Bugs

Lets use this thread to list any bugs or problems we have come across.
By request of "test878", here is a list of all bugs in this thread. Did my best to add everything. If I missed something, or if anything I posted isnt considered a bug, please let me know and I will update. Lets first start off with the most important bug...
I can't seem to install Cyanogenmod7 at all and the bootloader is tied up pretty tight.
Anyone noticing any graphics lines in their widgets? Im getting some kind of glitch over my Youtube widget, and my Twitter widget. Update: Rebooting fixed it for now, will update if it comes back.
When I reboot the phone, all my apps that are on my sd card icons don't show up. I just get the generic green android icon. I tried messing with fastboot, didn't seem to help.
But my biggest bug and very noticeable problem is that the camera will freeze. This happens a lot. The picture will snap, the preview will come up and stay there. The phone is not frozen because I can hit the home button, but the camera will still be stuck on the same preview even after I hit the icon. Eventually stops after opening it several times. No restart required.
when you have the headphone jack plugged in, and you try to reboot the phone tries to reboot bug hangs with black screen. pressing the power button in any number of ways does nothing but turn the back light off and on (the screen displays nothing)
I have the 100% wake lock issue, its really pudding me off! Does anyone else have this??
WiFi will randomly (not really, it's easily replicated) drop out when connected to a Bluetooth headset, and will not turn back on unless you switch to handset or speakerphone mode.
I am having trouble with the clock/weather widget. It will not find my location for the weather
After said restart and another after it, when spinning thru the different windows, it shows all of the screen with widgets on them as blank until you stop on the different screens.
apps that I put in folders on the rosie and then later remove from said folder somehow show back up in that folder randomly.
HTC trace kb only works the first time or two, then stops working, even though it's still on in settings. Works again if you disable and the re enable, but fails the same way right after.
I think that the sync icon sticking is caused by HTC Watch. As soon as I deleted my account in the app and rebooted it unstuck.
The sizes are off in some apps because of the lcd density.
The notification light for gTalk is still flashing when after you open and reply to a message. To get it to stop, you have to back all the way out of gTalk, and go back to the message you just received.
Phone hard locks on Youtube after playing 3D videos. Screen turns off and capacitive buttons stay lit. Had to pull battery out to reset the phone. Happened on 2 different Evo 3Ds.
Camera goes to/defaults to 2D mode, despite the switch being in 3D mode
The music player is messed up for me with artists that have multiple albums.
When i send a message to someone it shows a green dot in the message app like i received a new message but it was just my message i sent
WIFI will not connect to a corporate secured network after reboot. I have to 'forget' the network, and start from scratch, each and every time.
Noticed when you snooze a calendar alert from the lock screen, it never re-alerts you, it acts like you dismiss it.
Seems the notification sound i have set does not play for my exchange mail. Plays for new gmail, but when new exchange mail comes it, it plays the 'Alpha' tone.
I set up my personal email last night using IMAP. On the lock screen it shows I have 99+ unread emails but on the home screen and in the email section its showing no unread emails.
I'm having a problem with Exchange. In People, the contacts can't be viewed Last Name, First Name, no matter how I try to configure the View settings.
I have had an issue with the camera freezing up on me. I'll take a pic, try to share, and it freezes. Hit the home button and it will respond.
my Yahoo! email won't show ANY of my mail using the native client.
3D will stop working in everything but the camera and gallery. Youtube won't play anything in 3D (just displays 2d), and The Green Hornet won't play in 3D. A reboot fixes it temporarily.
Can't get watchESPN to actually play video.
Anyone having problems with the home button not responding? I have to turn the phone off and then back on before it responds.
When on 3G, the youtube app does not function well. It plays random videos contrary to what you selected to view.
I had a weird bug where the lockscreen was black from about the middle of the LCD screen all the way down, and the top half of the screen was the ring to unlock and my 4 icons. Thing is, I couldn't unlock the screen, or open any of the apps. I tried sleeping the screen on and off, didn't fix it. Finally did a battery pull and that fixed it.
I noticed that when you plug the phone in to charge it always seems to kick the brightness up to the max and you have to turn it down.
the watch (green hornet) app has suddenly stopped displaying 3d.
I'm having an issue where there is a popping sound before the start of any audio. It happens whether i'm starting a text or listening to any audio. It may be an issue with my phone specifically.
Since the OTA I have started having random touchscreen issues such as the touchscreen being completely unresponsive.
Also I will touch on a certain app and another app will start instead.
Another bug when phone is in landscape mode the keyboard calibration tool doesn't show up as an option.
Sometime when I try to press the screen nothing respond in sorting place or move. Also when i restart the phone the phone don't power back up I have to turn it on normal.
Brightness problem. I have my brightness set very low, but when I use the 3d camera to take some pictures, the brightness seems to reset to full brightness. Soon as I go back in display settings and touch the slider just the slightest, it fixes itself.
When I make a call the earpiece seems to go quiet when ringing and then turns up as well. It's like the ringing is fading in and out when I'm making a call.
Download app from Market (FeedR and Currency Exchange) the last two days. Apps installed okay, but when tap to launch app (Both apps), the screen went black, none of the capacitive buttons nor the power button will awake the phone. Have to do a battery pull.
I was watching a Youtube video in 3D and had an incoming call. The screen went black immediately and I had no way of answering the phone, and I got no response from any of the capacitive buttons or power button. I missed the call, and the screen remained black with still no response from the buttons. Eventually I tried the camera button and it worked. Camera app launched and I had full control over the phone again.
phone reboots when i take out usb cable
I just noticed that the Weather Lock Screen doesn't display 3-digit temperatures correctly.
The music player pause and skip forward buttons show a pressed state at all times.
I cant even see the green hornet every time i go to it or to htc watch it tell me i need to update my software and i already did that. And after I tried it again it tell me there is no more software updates for the phone.
When you click on the power button and select restart, it actually shuts down the phone and you have to power it back on.
So I was on the phone today when my battery died and my phone shut off. I went to charge it using my car charger, and the light did not come on. Waited till I got home to try my normal charger, same thing. Decided to take the battery out and now it works fine. Not sure what happened, guess its a.....bug.
I'd appreciate it if anyone can confirm a bug in the calculator app. When I open it, the entire app is huge, its not formatted properly.
Apperantly screen is not big enough to read triple digit temperatures.
top half of the screen stops responding at times, usually after using one of the sprint or HTC apps. pulling the battery and restarting fixed this, cant select power off as it is in the top half of the screen
In the stock messaging app, when using a signature it always saves a blank message as a draft after sending original message.
I've been having random bugs like my screen going black or 3D/2D not turning on off correctly but most of it is stuff that can be corrected easily. The most noticable one I've notices so far is where everything on the lockscreen(background and all) is smushed in the top half of the screen but you still have to drag it up from the bottom to unlock.
about 40% of the time I turn the screen off on my phone, the screen will turn itself back on a second later without me touching anything. Turning it off a second time always keeps it off.
Sometimes, my music will start playing on its own, even though no music player is open
I also have experienced the SD card items Icons not showing up after reboot. Also see the Force Close Pandora pop up when I have not even activated it. Good to know they're looking into it.
My sms messages which were recieved within an hour of rebooting and read, are remarked as unread after a reboot. Annoying.
Seams like some sort of data shadowing.
I just started up my camera and there were horizontal (in landscape mode) green static lines (about 1/8 in thick) across the screen. About 10 which were equally spaced from each other and I could still see what the camera was pointing at. It would not go away even as I switched between video and still, portrait and landscape.

I have not tried any of the Fr3vo stuff so I am fully stock and on the .7 OTA. I rebooted the phone and it is gone.
When I pause the music player in the middle of a track, go off and do stuff in other apps or in the real world, then come back, often the music player has reset to the beginning of the track.
In the browser, drop-down lists don't work on some sites.
My icons are also changing back to the default green android for apps placed in a folder.
If I'm in the camera in 3D mode then put my phone to sleep using the power button, then press the power button to bring it out of sleep, the unlock screen has the parallax 3D on. The lock screen isn't in 3D of course, but you can see the distortion as if it were stuck in 3D mode. Unlocking your phone fixes this.
twice now I've had my phone just shut off. Not reboot. I go to turn the screen on and nothing happens. I hold the power button down and the HTC splash pops up and the phone boots.
Notification bar just disappears every once in awhile. Have the restart the phone to get it back.

I was able to connect to HTC Sense.
Started up Spiderman 3D. Played for a minute. Hit the home key. I was at the Sense UI but it was trying to display everything in 3D. Had to go back into Spiderman and quit normally and everything worked fine again
Got it working by visiting Htcsense.com to make an account.

On your lock screen if you remove the Phone icon it's not in the list to add it back again if you wanted it on the lock screen

Did you take the OTA update?
Try a hard reset that should fix it

Yeah i did the Over the AIR update, it's not a big deal for me, just something i noticed, that was missing when choosing what apps you want in the lock screen bar
Still can't DL anything manually from the Market. I talked with Bonnie from CNET who did the review from them and she said the market was working on her review model.
I just got another OTA update when I booted back up. Maybe this fixes it? (I got a OTA when I first activated it this morning)

just because it shows in the battery as 100% doesn't mean it's truly 100% battery, i installed Battery Time lite, the OS showed the battery at 60% but battery time showed the batter at 53%, so you could be just a little impatient

you do realize that when the bar reaches the 100% mark the animations stop but it's still charging, once it reaches over the 90% the battery meter shows 100% when in fact it could be 91%

My 3G and 4G keep cutting out on me.
someone mentioned this but this is HUGE. The phone icon disappeared off the lock screen and the icon is gone from the apps menu.

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem

[Q] Problem when my phone is recovering from Sleep mode

Hi everyone !
I'm new here (and not a native english speaker, so apologies in advance for any grammar mistakes)
Before making this thread, I looked for info here, but I'm not sure for what to search.
I'll try to explain my problem here.
I bought a Galaxy SIII from my provider 3 weeks ago and everything looked fine, till last week.
Some times to time, with no apparent reason or cause, while my phone is on sleep mode, on my desk, or in my pocket, playing music, I have the following problem: when I push the on/off button to wake up my phone, my screen is turning on, taking me to the lock screen.
But, my screen brightness is very low, like set to the minimum.
And when I draw my unlocking pattern, screen goes black.
Bottom buttons are lit and my phone seems to be OK, I can feel haptic feedbacks.
But the screen is black.
If I push the on/off button again, screen stays black and bottom buttons are not lit anymore, as a usual Sleep Mode.
If I push on/off again (depending on how much I wait between 2 on/off):
- My phone awakes from Sleep and takes me again to the unlock screen, brightness still very low. And after the unlocking pattern traced, black screen again
- If I didn't wait enought after putting it into sleep mode, in this case, I don't have to redraw the unlocking pattern. I'm back to my home screen...
for 1/4 of a second, stilll with brightness at the minimum. And screen goes black.
And after a serie on onoffonoff, boom, my screen is back to full and normal brightness and everything is OK.
At the beginning, my phone did that once in a while. I thought at the time ti was after pushing the on/off button while using a CPU/RAM hungry app, my phone struggling to recover....
But now, it's totally random.
Depending on .... I don't know what, I have to do the onoffonoff thing 2, 5, 10, 50 times in a row so my phone can recover from is half comatose.
Yesterday, I could not use my phone for half an hour ...
and if someone calls me, I hear the ringtone, but screen stays black.
I can answer the call (but not knowing who's calling) by sliding on the part of the screen where the slider normally is.
Funny thing is about removing the battery. It doesn't solve my problem.
When I do so, my phone boots, I see the "Samsung Galaxy SIII" boot screen, on low brightness (whih is not normal ...)
After that, I normally have another boot screen with my provider's logo and tone. But screen goes black again (but I still here the tone)
Then I realized it started to happen when my phone proposed me a Samsung update.
I tried to reset my phone to factory settings but it didn't work, the update was still here.
For a while I thought my problem was solved, because my phone behaved normally for 3 or 4 hours, without problem.
But it came back.
I found on the internet several "almost-same-problems" without proposed solutions.
Like checking if the proximity sensor was blocked by a protective transparent plastic sheet, or a case.
I tried to to remove mine.
Didn't work.
Some people said it was linked to their phone trying to acquire a wifi network.
My wifi on or off, withiin or without the range of a wifi router didn't work ...
I tried to note things down about what I did, when, how, app launched before the problem appears.
I checked battery info (temp, voltage, etc).
No pattern emerged.
So.
Hs anyone of you enountered the same problem ?
Do you have ideas, solutions I can use ?
Or maybe a voodoo prayer ?
I could sent it back to my provider which will bounce it back to Samsung. But it will take ages (3 to 4 weeks ...) :'(
Thanks in advance !
do a factory reset, go completely stock
if that doesn't help, send it in

That's what I did.
I tried by going into the Parameters menu, and reseting.
I tried by booting my phone with Vol+ / Home / Power buttons to access a console mode and do a wipe data/reset.
The problem is that my phone got an update like one week ago from a 4.?.? to 4.1.2.
And even with a reset, my phone reboot with the 4.1.2 version, which seems to cause this problem.
Or maybe not, but I can't be sure.
As I said, after a factory reset I did yesterday, everything went well for 3 or 4 hours and the problem reappeared.
send it to the service

Strange screen behavior

Hello,
Yesterday I have unlocked my phone with my finger print (like I always do) and it took about 5-6 seconds for the screen to show something. The backlight turned on rather quickly but the screen remained black. After the screen turned on, it had a bad case of screen retention, the colors were also darker and I could not use the buttons from the bottom of the screen. A reboot solved all this problems.
Also, sometimes when I turn on the screen, it quickly goes dark and the slowly comes back to the initial state. During this time I cannot use the touch screen. It is like it does the wake up of the screen all over again.
I think this is a software issue (I have V20C on H850) and it might be related to the always on display. Also, all of these problems happened when I woke my phone using only the finger print (not pressing the button or knocking on the screen).
Did anything like this happen to you?

Strange issue on Android Lollipop

I have a cheap LYF phone which has a strange issue. When I switch on the phone and try to open the lock screen - it flickers to the wallpaper, then goes blank and couple of seconds later relocks the screen. And it repeats the cycle over and over again, automatically. Screen turns on, it goes to the app drawer, screen flickers, goes blank and relocks the screen.
Even the top half of the screen which shows network connectivity flickers between showing no sim, then no connectivity, back to no sim. It is also losing battery at a rapid rate because of these changes. It doesn't even charge when the phone is on. Charging while the phone is switched off works fine.
I made a video about it, apologies for the huge background noise:
