I got the Android 4.3 OTA update more than two weeks ago. Since that time strange vertical lines starts to flicker when I do not touch the screen (See attached screenshot). The first time when I can see these ugly lines after turning on my device is the PIN code entering screen. After that I can see them on the home screen and every app as well. The problem does not occur if I charge my device.
This issue has nothing to do with developer options. I tested it with "disable HW overlays" option and other settings as well but it does not change anything with this. I also tried a factory reset and restoring a clean Android 4.3 using google's factory image for nexus 4.
It can not be a hardware issue because you can see it on the screenshot that was taken with my device. Furthermore, I had no problem with Android 4.2.2.
Has anyone encountered this problem? Can anyone help me?
Ewww, looks like a kernel graphical glitch.
You will have to reflash the kernel, do you have a custom recovery?

Currently nothing is enabled. I turned off every developer options. But I tried with different options from the "Hardware accelerated rendering" category. These options have no effect on the problem.

No I don't. What does a custom recovery mean? I don't want a custom OS. I want to use stock Android 4.3
are you rooted? Custom kernel?

No, my phone isn't rooted and I don't use a custom kernel.
Do a factory reset ? If that doesn't work you can always flash the img file through adb. But in order to that you would have to unlock boot loader

A custom recovery is a recovery like on a computer but it is not stock so on Android there are Recovery's such has TWRP and CWM.
Flashing the stock kernel via recovery will not replace the Android OS, just the broken kernel.
Basically a custom recovery let's you wipe your device in many ways, repair the OS, Backups, Flashing kernels/ROMs/Fixes/Addons and much more.
If that fails then unlock the bootloader, go to the bootloader and use this tool to get everything back to normal: https://developers.google.com/android/nexus/images#occamjwr66v
EDIT: Oops, flashing a custom recovery does not fix the kernel in the same time of course, you will have to flash that kernel using the flash feature.

Hi everyone I was just wondering if its possible to downgrade my nexus from 4.2.1 to 4.1.2 if I'm not rooted. I'm currently not interested in rooting my device so is there a way to do it without rooting/unlocking?

Have you tried one the took kits available? Check around in the Nexus 7 original development section. Look for Wuggs.

I looked at his toolkit but it basically says that I have to root in order to even use the toolkit so is there a way to downgrade without having to go through that rooting process? For now, I don't want to root my nexus

Don't try to root it you'll only manage unlocking the boot loader then when you try and root it it will get stuck in fast boot mode I tried about every rooting program but it could be because my Comp is running windows xp lol

It's so easy to just reflash stock and relock the bootloader that you really have nothing to worry about. If you want unrooted stock 4.1.2 just unlock the bootloader, then flash the stock image of 4.1.2, then relock the bootloader after. It's a really simple process.

If i'm not mistaken, as long as you flash back to 4.2.1(which is the os it came with when u got it out of the box), and then re-lock the bootloader, unroot, then your warranty wont be voided mate. hope I helped.

Yeah, I've done this plenty of times with my Nexus 7 and even the Verizon Galaxy Nexus. As long as you're on a stock image with a locked bootloader, they won't give you any trouble or claim you voided your warranty, as there's really no way to tell. I've gotten into the habit of unlocking and rooting my device as soon as I get it, and if I find a problem I just revert back to a stock image, relock the bootloader, then send it back in. I have yet to have a single issue.

You don't need to worry about saving your stock image. The person above you is talking about saving the stock image to return to after flashing a custom ROM.
There is no way to revert back to 4.1.2 without root access. Doing a factory reset, about the only thing you can do without root, will only return you back to stock 4.2.1
My advice just stay on 4.2.1 whatever your issue is with it.
Otherwise use a toolkit. You will need a PC and the 4.1.2 image. Wugfresh has a website. I would start there.

I actually was just referring to the stock images you can get directly from Google or from goo.im. It's easy enough to just use the 4.2.1 stock image from Google to just restore back to how it shipped, and then relock the bootloader.

Completely agree with this... I have, on several occasions, reflashed stock, switching between 4.1.2 and 4.2.1 - (for me, it was more of an exercise in learning about fastboot and adb... and making sure I had TRIED AND TESTED factory images on my laptop as contingencies should anything go wrong when I came to start flashing custom ROMs).
-----
You don't need root to flash a factory image... everything is done with fastboot; with the Nexus 7 in FASTBOOT/BOOTLOADER mode (from complete shutdown, press and hold Volume Down button... whilst holding, press the Power Button).
(Root is meaningless anyway, here in FASTBOOT/BOOTLOADER mode, since /dev/block/mmcblk0p3, the SYSTEM partition, hasn't even been mounted yet - so no SU binary available... whether or not it exists, it's sort of irrelevant).
- here, for example, is the flash-all script from 4.1.2 (nakasi-jzo54k)... (Nexus 7, WiFi model only).
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.41.img
fastboot reboot bootloader
sleep 10
fastboot -w update image-nakasi-jzo54k.zip
After running this script (flash-all.bat if in Windows, or flash-all.sh if an Apple user) you can optionally choose to lock the bootloader with... (if you're concerned about warranty issues).
Code:
fastboot oem lock
-----
If it was the case you needed root to run...
Code:
fastboot flash [partition to be flashed] [IMG file to flash]
...you wouldn't be able to flash a CUSTOM RECOVERY like CWM or TWRP... and thus, you wouldn't be able to flash Chainfire's UPDATE-SuperSU-v1.00.zip (http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip) in order to gain root in the first place!... (you see the paradox!).

Hi XDA.
After growing a pair of balls I've decided tonight is the night that I am going to unroot my phone, put it back to stock ROM and get it off of franco.Kernel. I am doing this because I want to start fresh and get it on Paranoid Android.
(I currently have a January nightly of CM 10.1, franco.Kernel r53 and unlocked bootloader whatnot)
I am looking for the stock kernel for the Nexus 4, but am worried about flashing the wrong one. I'm not saying like I'm going to flash a Samsung kernel or something stupid like that, I just mean that since I am on android 4.2.1 and if I flash a kernel that is made for android 4.2 can I screw up my Nexus 4?
Any tips?
Thanks a ton.
Edwin
As long as the kernel is for the Nexus 4 then you should be okay. You can get all the resources here.

make sure your download isn't corrupted and you downloaded for the correct device. Should be fine.
What's the point of going through all the time to unroot and flash back to stock?
Why not just do a full wipe and flash paranoid android?

I have heard of the digitizer blowing from flashing wrong kernels. I suggest only flashing kernels made for your specific device.
Sent from my Nexus 4 using xda app-developers app
You should add one more ball to that actually make it two more as you are at it. First you should install latest cwm recovery and root your phone. Then go to the recovery and make a backup. After that you can continue with flashing custom Roms and kernels.

Hello! I updated my nexus 4 to 4.3 with the OTA, but why do so many people have trouble updating their N4 to 4.3 when they are running a custom rom?
U can easily flash 4.3 builds through CWM or TWRP. Or is there a difference between flashing through recovery and flashing through fastboot?

Flashing through fastboot means doing it thru your PC with commands on the CMD and i think it uses different files ( I'm not so sure about that)

At least to me, i tried flashing thru custom recovery and it gave me an error every time so had to flash the image thru fastboot. Its (i think) the easiest way if you don't want to find youself having many problems.
I have a friend who has an N4 8GB, after the update to 4.3 from 4.2.2, the in-call sound dissapeared.
After tinkering with it, while unrooted, we found out that the phone is thinking the earphones are alway connected, even though they are not.
We downloaded an app that disables the earphone jack and it worked, but what a crappy workaround.
So, is there a fix for this? It was working on 4.2.2... I want to fix this while still being unrooted and stock.
I can give details if required.

-baseband and bootloader got updated automatically to the latest.
-build number is JWR66Y, i saw people factory resetting their phone but it didn't solve that issue, so I'm guessing downgrading to JWR66V?

Try going into the stock recovery and wiping the cache. If that doesnt work, do a factory reset using the stock recovery.

Try flashing the 4.3 baseband and see if it loads. If it does then I suggest you use a hybrid baseband by morrislee.
