Screen issue on device unlock - Nexus 4 Q&A, Help & Troubleshooting

Hey.
When I press the power button to wake my screen the backlight seems to start lighting up ( from the center of the screen to the borders) but nothing is shown.
I press the power button again, screen goes completely black, I press it again and the screen wakes as it should.
It seems to me it only happens if the device has been on standby for a longer period of time (1~ hour).
This has been happening on every ROM and kernel I've been using (4.2, 4.2.2, 4.3, 4.3.1, 4.4 and their respective stock kernels as well as NEO and Franco kernel in several revisions).
I've been using lots of different CPU, GPU and voltage settings over time but the issue persists.
Strangely I never had this happen when receiving a call or when the alarm goes off in the morning.
I have no idea what possibly causes this. Maybe anyone has a clue?

OK, so I have been having similar issues, but mine is worse!
When I press the power button to unlock, I get a dim back light but no display. I then press power again and you can see the faint back light turn full black just like when you hit that button to turn your screen off, then I try again to turn on my display and I keep getting the back light on on off cycle. I've tried using my connected bluetooth to make a call to see if the display pops up and nothing.
Eventually, I have to hold the power button down until I force the phone off, and then turn the phone back on in regular mode (not safe mode which maybe I should try even though I have no idea what that allows me to do) and continue with what I was doing. Today is the first time I decided to search this problem. My N4 is about 10 months old, is rooted, no ROM, but Franco Kernel and overclocked to 1512. BTW, I also adjusted the overclock speed and tried plugging in direct charge when I get my no wake up problem.
This has been going on for about a month, has been the only reason a reboot has been needed, and is becoming very annoying. I also use wireless charging. I do not know if a complete wipe of the phone getting it back to stock would help, but I really would like to fix this. I want the N5 but realistically I don't need it yet. The N4 is in perfect physical condition, and until recently, very reliable.
So no, you are not alone!
Need help here though!
Thanks all.

Yeah, I have the exact same problem.

When did yours start doing it?

It's weird. It seems to be totally ROM and kernel independent. It also seems it has nothing to do with the governor or clock speed. Neither with the voltage. It happens while on a/c and while on battery. No matter the temperature, too.

I can't believe this issue is so unknown.
I guess I'll have to figure out how to logcat and see if I can find any hints.

Maybe someone who's good at reading logs can shed some light. This is what my log shows from the first time I press power, over pressing it again to turn the half lit screen off to pressing it a third time so it shows up normally.

My wife's n4 is having the exact same issue and it's a completely stock phone.

If it's the same issue that used to happen with the HTC HD2, then it's probably the power button.
To test this out, enable the option "Volume button wake". That option allows you to wake up the device using the volume buttons (Please note that I have this option inside Carbon settings > buttons, it might not be in stock or it might be in a different place and name depending on the ROM). Now stop using the power button and use the volume button for a while instead to wake up the device, then see if the problem persists.
Edit: Also try using "double tap status bar to sleep" or set the screen timeout to something short (in short, don't use the power button to put the device to sleep)

I'm already using a mod that turns the back button into a power off button on the home screen.
Please note that this only happens if the device is turned off for a longer period. If the device is awake I can repeatedly press the power button and it will react instantly.
It seems to me it happens when the device is in deep sleep. If I press the power button after the screen has been off for let's say an hour the screens backlight will turn on and show a very light whiteish dim but nothing is shown. So I have to press it again to turn it off (screen goes black) and again to turn it on (instantly works then)

that is just a wakelock taking longer to execute/finish, had few of those, not a hardware specific thing(even more that our s4 pro can´t even do a full sleep) some app is causing that,for me happens mostly when I have too much apps that synchronize accounts

I've ready tried waiting after the first press (when the display just has a light dim) but it never fully turns on unless I lock and relock it again.

[Q] Camera broken

Hi all,
the camera on my Glacier appears to be broken. Any "camera related" app I try to launch force closes after a few seconds. This is true for the built-in camera app, for a barcode scanner app and even for a torch app that would use the flash and not really the camera.
I have already cleared the cache and Davlik and have fixed the permissions to no avail. I ran a logcat from launching the camera app until after I clicked the "force close" button:

My next step now would be a factory reset, but before I do that I'd like to see whether anybody's got a better idea. Any help is appreciated.
Thanks.

I just did another reboot and launched the camera app, again. On the first attempt the behavior was the same as before: the app force closed after a while. On any subsequent attempts to launch the camera app I now get the error message "Camera Error / Cannot connect to camera".
We need more info. Are you rooted? What rom? What kernel? Any mods, themes? Things like this can break stuff.
If youre rooted and running a custom rom, just reflash the rom from a full wipe.

I would try full wipe and flash the ROM again.
Sent from my HTC Glacier using XDA App
the device is rooted; I am running CM 7.0.3 with kernel 2.6.35.14 demonspeed v9. It's probably the kernel that causing these problems. After re-flashing CM 7.0.3 (thus going back to the kernel that comes with the ROM), the camera started working again ...

Camera force closing?

Recently the camera on my z just force closes whenever I try to use it, whether its the camera app, or another app that uses the camera, I.e; barcode scanner, this is fairly recent, and I have tried a few different roms, with no success using my camera again, the roms I tried are miui, cm7, and virtuous unity, so I have no idea what is causing the fc's, and was wondering if there's anyone here who can help me?
Sent from my HTC Desire Z using XDA App
are you restoring system data with TB? are you super wiping and clearing all the caches manually before flashes?
Yeah, I have tried a full wipe (system,cache,dalvik?), and a clean rom without restoring anything with TB and I still get the FC issue.
Sent from my HTC Desire Z using XDA App
i suppose it could be hardware related, have you tried any rooted stock roms with a stock kernal etc? See if that works? I know the wrong kernal with the wrong rom will break camera functionality
I haven't tried that, I'll have a look around for one, any you'd reccomend?
Sent from my HTC Desire Z using XDA App
Update, tried a few stock rooted roms here, with the htc kernel, still no camera :/
Could you do a logcat ? At least you would see whats happening when the camera Force Closes?
Good call lol I always read longcat lol

those are the parts of the logcat i have refering camera, if you'd like anymore of said logcat, lemme know!
I'm having a similar issue, but the camera only force closes if I try to use a shooting mode outside of no effect or black and white. All other modes cause a crash

I'd be happy with that, i only ever used normal mode anyway :/

[Q] Nook color dramatically drain battery

Helo, my nook color running Phiremod 7.1 Stable release. Before I tryed CM9 -> MIUI -> CM7 Nightly 253m. Before install, I cleared system, data, cache and dalvik cache. In any of this releases I have one bug. Nook drammaticaly drain battery, also in sleep mod (~20% for 8 hours), airplane mod doesn't resolve this problem.
Another bug, that battery indicator doesn't appear in tray, only percentage.
If I boot into recovery, and enter key test, there is spam "key 108 presses" or "key 103"
If I connect to device using adb, in logcat I can see this, than device in sleep mod:

Is there hardware error or ... ? Help me please
This probably has something to do with running CM9 and then putting a CM7 build on top. While generally formatting the boot isn't something i'd recommend, i've found it to be useful when switching from CM7 to CM9. I would assume this to be true in the opposite direction, but if you're uncomfortable with taking this risk, perhaps you should wait for a second opinion.
After all I format /boot /system /cache /data, back to stock 1.0.0, than update to 1.4.1, no matter what I do, but the power from battery leaks the same.
Can it be hardware issue? And if it is, what exactly can it be? Bad battery or short circuit in usb port?
How can I help myself. Turn off my nook, disassemble it, take battery out, plug in wall outlet, put battery in. Everything works great.

Nexus 4 weird noise. Video

https://www.youtube.com/watch?v=MtYyEeNjKks&feature=youtube_gdata_player
My mums nexus 4 has been making a weird noise for a couple of days now. She was on paranoid android 2.99 when it started. I wiped data factory reset cache and dalvik then installed pa 3.00 and the noise was still there. I then flashed the backup I had made of stock 4.2 and the noise was still there? Pretty weird stuff like. Anyone any ideas what it could be? That's been 3 different roms!
Cheers

Re: Nexus 4 weird noise. Video (Fixed It)
My god I can't believe it. She had gotten a new case for her phone that held credit cards. As soon as she opened it up and the credit card was directly behind the noise happened. It was trying to scan the NFC chip in the credit card. Haha!

My mums nexus 4 has been making a weird noise for a couple of days now. She was on paranoid android 2.99 when it started. I wiped data factory reset cache and dalvik then installed pa 3.00 and the noise was still there. I then flashed the backup I had made of stock 4.2 and the noise was still there? Pretty weird stuff like. Anyone any ideas what it could be? That's been 3 different roms!
Cheers

[Q] Freeze and reboot after accessing SD Card / GC_EXPLICIT in Logcat

Hello everybody,
I got a Nexus 4 with CyanogenMod 10.1.3 RC2.
Recently my system freezes and then reboots on a regular basis. I tried to reproduce the failure and it seems to be related to accessing the sd card. A very reliable way to reproduce the crash is:
Connect the device via USB to the PC
Open the SD Card
Select all entries in the root folder of the sd card
Open properties so that the system calculates the folder / file count and the total size
At some point in this calculation android freezes and reboots
But the system also crashes at other occasions. Today it crashed after I took a screenshot of my device and deleted it afterwards using the Gallery App.
Just before the crash my logcat shows:

Does anybody have an idea what could be wrong here? Do I have a broken sd card? Or is it a bug in CM?

GC_EXPLICIT is the garbage collector. It frees memory. More about it:

Thank you. I know that this is the garbage collector. But I wonder why it is so excessively triggered by the VM when accessing the meta data of files on the sd card. Is that normal behaviour? If so, a hardware problem seems to be even more likely. Is there a way to scan my sd card for defects?
Or do you have any other idea what could cause this failure of my device?
Thanks

So far I only tried with this ROM. But I already experienced this with prior versions of CM. I had 10.1.2 before.

Try other ROMs, like stock 4.2.2 rooted, 4.3. If they all do the same, then it's a hardware fault. If they don't, then you need to reinstall your ROM.
