[Q] Pixelated flashing lines on display screen - ONE Q&A, Help & Troubleshooting

I've been having screen/display issues (not the yellow hue and separate of the touch screen sensitivity problems). Every now and again, I get flashing, pixilated horizontal lines. I don't see any dead pixels and when it's not blipping the screen seems to display flawlessly, so I'm not sure if it's a software issue or if the hardware is failing. Also it's not isolated to one particular area, it jumps around. Anyone have this problem? Any fixes? I haven't been able to find anything on it. PLEASE HELP. Below is a video of the problem.

Are you completely stock? Any custom kernel? Any rom?
Usually it's a kernel issue - tearing, but it's only present on custom kernels (never came across on the stock cm11 kernel). You might wanna try a different kernel though, if you're comfortable with that.

I have the same issue on my stock rom with stock kernel. the only thing i have changed was the developer options. i changed the screen animation time.

I had exact same issue during recording a video yesterday night !! I am latest mahdi and latest franco...
Funny thing is it went away once i exited the camera... what rom and kernel are u using ?

I've been having the same issue too. I don't have a solution for you, though. I haven't been able to find much about it.

Same issue here, stock all the way, only been since latest update. The update didn't flash properly, it gave an error stating it couldn't be located but i went through the files and it was there and then upgraded OK

I had the same problem. Selecting "Force GPU Rendering" in developer options cured it.

i have stock everything. i'm not rooted.
a reboot fixes the problem temporarily. shoot, all the issues i've ran into with this phone thus far (like the GPS not locking on) is fixed by a reboot. i know a reboot is good to do every now-and-again regardless, but having to do it constantly to fix issues is the sign of a failing device and is very annoying; it shouldn't be something you have to do with a brand new device.

i am facing this too randomly. Am on rooted 38R with Franco kernel. Rebooting is a temp cure but it will frustrating to keep doing it.

This happened to me after getting 38R. Fortunately it hasn't been back since a hard reboot. It would show up on Youtube & when dragging down the notifications area.

I had this today on PAC ROM. When I unlock phone and lock ring animation dots flash up made lines come across screen not sure what it was or why. Just rebooted phone. Back to normal. But trying out vanir later tonight try something abit different.

Also experiencing this here.
Stock ROM, clean 38R install.
Stock kernel.
Rooted, with a few xposed modules.
Started a day or two ago. Haven't found a way to recreate it. When it does happen, a reboot remedies it, but only temporarily.
I will attempt to screenrec it the next time.
I find it interesting that I only see mentions of this starting recently.

Same problem for me since the last update. Restarting the Phone solves the problem for some times. Maybe a driver issue?
Glad to see that it is not a hardware issue.

Same here
Same here, mahdi-2.8-bacon-20141001 ROM, enabled "Force GPU rendering" in Developer options, let's see if this comes back!

I have the same problem on latest cm nightly with stock kernel. And dev options works sometimes but it resets on reboot and my phone reboots randomly all the time. I'm starting to hate this device

I also have the same issue on Stock 38R update + franco kernel r27
It happens after the latest kernel update, before I never had this lines.
Lucky for me I don't have any reboots now but I fear that will come to pass as well.

Got the same problem with Mahdi Rom 2.8 - 20141016

Will be solved in Franco Kernel r28,he just confirmed this on his kernel thread.

same issue here. i have to reboot. its happened on stock and AK kernel. will try enabling force gpu rendering and see if it comes back

Green Screen/Artifacts - Hardware or Software problem?

Hello everyone,
I've been having quite an interesting issue on my NS4G. I'm currently running the latest available CM7 nightlies/gapps, as well with Pete Alfonso's kernel. The underlying system in the phone (radio/etc) is all running the current latest available from Sprint as well.
Now the issue in question, I've been having an issue that seems to be occurring more and more frequently on my phone. Now because I am already running a custom ROM and not just stock, this makes me unsure if the issue is coming from the software, or if there is an actual hardware issue with my phone.
Occasionally (I would say as infrequently as once every 2 days or so) when I unlock my phone with the power button, for a split second after the CRT animation I see my phones screen as all green (with a hint of purple), almost the color you associate artifacting with. Now I am not overclocked, but I am running this custom kernel. But the thing is, I'm not 100% on this, but If I remember correctly I do remember seeing this issue on other kernels as well before (I've been running Pete's for some time now).
I also occasionally experience issues with lets say finishing up a phone call, and my phone may lock up with that green screen w/ purple, and then CM7 will automatically reboot the phone for me. I've also experienced my phone rebooting into "Safe Mode".
Essentially what I am wondering is if anyone can shed some light, are these just software bugs that I am running into that other users are experiencing as well, or is this an issue with my phone?
Thanks everyone!

go to the main settings, cyanogenmod settings, display.. turn on the screen off animation. then go back to cyanogenmod settings, lockscreen, delay and timeout, turn both screen timeout delay and screen turned off delay to immediately. that should fix the green screen.

[Q] Problems with touchscreen ?

Hi there,
someone has problems that the touchscreen is not responding?
Have CM11 - current nightly, Fournace kernel 1.0.2 and OPO lockscreen flashed ....,Only the lower right corner is responsive to inputs.
I had the problems also 2 times with the CM11S-ROM.
Has anyone else this problem?

I have the same problem. It's intermittent and goes away after a while but it comes back often enough to make my device unusable when needed. I literally can't answer calls or log into my device because of this. Is no one else having this problem? The issue persists into recovery so it might be hardware.
Franco r13 has new touch drivers implemented. Try it.
OP you say it as if your screen is never responsive, only in the bottom of the screen. That sounds like a RMA.
I will look into Franco r13 tonight. In the meantime, here is how my problem happens:
- Most of the time touch screen is working as expected
- Sometimes the touch screen becomes unresponsive to many areas on the screen, but some small areas still work
- When the above issue occurs, it is only temporary. If I let the phone sit for a few minutes it usually comes back.
- Restarting does not fix the problem, and the problem persists into recovery mode (I forget which recovery I have, but it has touch screen input)
- The problem started with phone being 100% stock, although only after the OTA update a few days ago

Yeah, try Franco then. Mine feels better now. It wasn't too responsive before either.

Issues everywhere, hardware problem?

Hi there,
I'm experiencing massive issues with the Nexus 5 of my wife. Everything is basically broken
It started 2 days ago, the phone start rebooting without reason and heating a lot. Applications sometimes hang for a long time, or the screen stays black with only the notification bar displayed.
Wifi is never able to connect, even though the welcome screen is able to display available wifi. On the welcome screen after a fresh flash, nothing happen when I enter the WIFI password and try to connect. Only the "ignore" button is available, as if I have done nothing.
LTE connectivity seems to work, but I have removed the SIM card for further testing, so it's hard to say.
Parameters screen sometimes works, sometimes won't. Battery consumption screen never works.
The phone is never able to shutdown properly, it hangs forever on the shutdown loading circle; I always have to hard-reboot.
I changed the battery (I had a spare one ordered few days before the problem occurs just to see if it improves the battery life), with no luck.
When I opened the phone to change the battery, it is clear the heat come from the CPU.
I tried (I wiped everything each time in between):
- factory reset
- flash a stock rom from Google website (MMB29K)
- flash latest Cyanogenmod rom (ZNH0EAO2NM)
I have the same issues with any of those 3 roms. I captured some logs while running MMB29K and ZNH0EAO2NM:
Stock (MMB29K) logs: https://drive.google.com/open?id=0B-CDc3nzF3e3M28tM2xjTmJKa28
Cyanogenmod (ZNH0EAO2NM) logs: https://drive.google.com/open?id=0B-CDc3nzF3e3TVUtTmExZDBLUms
The only state where the phone is stable is when TWRP is booted, which is not so useful...
I'm thinking of a hardware issue, but is there anything else I can try? What do you think?
Thanks a lot!
Nobody?
I said the same thing in another post. The fact that flashing different ROMs with the same issues kinda point to hardware problem. I'd guess something fried on the motherboard and it's causing weird behavior. Funny thing, the other post also reported wifi not connecting issues, so I'm thinking there is something that breaks in older Nexus 5 phones that cause wifi issues along with other random reboot problems.

[HELP] Partially Blank Screen but otherwise active device OR Sleep of Death

Hello everybody,
I've got a problem with a Oneplus One.
First a brief history of the device. I got it on ebay with a shattered display about 1 1/2 years ago and replaced the display. Since then my girlfriend managed to shatter the display 3 times more. So I'm quite used to replace the display on this device.
Since the last display replacement (the 4th) the device developed a partial Screen-of-Death problematic.
Sometimes the display just stays blank, while the backlight is clearly working (you can see the blueish light in dark environments). Also the device reacts to touch and button inputs, like e.g. double-tap-power to start camera. Or double-tap-screen to wake up (you can feel the vibration or display input sounds).
I "just" have to wait about 10-20 seconds, try again and the display turns on without any problems. In other cases I have to try this a couple of times to wake the screen.
A hard reset is not necessary, the device will wake up sooner or later. In this aspect it differs from all SoD descriptions I found online!
An other strange thing is, after the screen replacement the device forgot all wifi networks. The wpa_supplicant.conf was empty. Strangely enough all other apps were OK, I didn't noticed any irregular acting applications.
As the device was sill running on CM13 I decided to give it a fresh nougat installation and assumed the SoD symptomatic would vanish.
Now after flashing back and forth different factory images and custom-rom's the SoD is still there and renders the device almost unusable.
I tried the latest CM13 snapshot and sultans CM13, which I have been using on another OPO without problems for a long time.
I also tried to install different original factory images.
cm-13.1.2-ZNH2KAS3P0-bacon-signed-fastboot_64GB.zip
and also another one I got long time ago from Oneplus to fix an annoying Wifi-Reboot-Problem. It contained additional image files like persist.img and reserve4.img.
I tried to turn on and off the setting for the proximity sensor that could interfere with the activation of the screen.
I tried different radio firmware's, as I could remember that there had been some problems in the past with incompatible firmwares, android versions and the proximity sensor.
I enabled and disabled all off-screen-gestures, although they are always working regardless if the display stays blank or not.
Unfortunately I've got no luck.
Literally every single android version I tried suffered from SoD. The only problem free thing is TWRP. Running the latest 3.1.1-0 I never got a blank/black screen on powering up the display.
So now I'm out of ideas and would be happy to hear any additional guesses to fix this problem.
I was also wondering if anybody knows more about the SoD. I couldn't find any information's regarding the causes of this problem. Is it hardware related or software?
thanks!
p.s. another strange thing I noticed now on the latest Slim7 rom (20170526). If I try to take a screenshot with power+vol-down, the screenshot animation happens. But a status bar notification from Android-System tells me, there is not enough free space to save the screenshot. But there is at least 40GB of free space.
I'm not sure if this is related to my problem or just to Slim7. And I'm also a little tired to reflash the device just to test this issue...
Maybe there is a problem with permissions or the flash memory?
p.p.s here a logcat. I couldn't find anything helpful.. https://pastebin.com/UWfwc1VX
Hello,
can anybody recommend an alternative kernel (for SLIM 7 rom), that allows me to increase the minimum CPU frequency.
I remember by doing that on a HP touchpad, I could avoid SoD.
Thanks!

Only this kernel is fully compatible with AOSP-based roms like Slim7.

Gravity sensor suddenly stopped working

Hi, it appears that recently the gravity sensor in my Nexus 5 stopped working.
At least it is what it seems by using sensor testing apps. And this makes it impossible for the phone to get its orientation (compass is not working).
Screen rotation is still working fine though.
Here is what happened exactly: not long ago I was using Google Maps, but the phone was a bit sluggish so I decided to reboot it.
After rebooting I opened Google Maps again and immediately noticed that the orientation indicator was missing (the blue "beam"), while it was present before the reboot. But I didn't care about it, and just thought that the compass needed re-calibration.
After a few days the orientation indicator was still missing, and the phone never asked me to re-calibrate, as it used to do before instead.
Then one day I launched Google Sky Map, and noticed that the view does not rotate automatically.
So I fired up a sensor test app I had installed (asd.vector.sensor), and no data is displayed for the Gravity sensor. Also orientation is not displayed and the info says that the gravity sensor is used to compute orientation, too.
Other sensors are ok, and as I already wrote screen rotation still works great.
Any clues about this issue? Did anyone ever experience this?
I'm afraid a system restore would not help...
I'm using Resurrection Remix ROM, Android 6.0.1.
Thanks.
If the problem exists on a stock ROM, it could be a hardware fault.

Ok yes, but I still do not know if it exists on a stock ROM.
Taking it the other way around... Do you think there is real possibility that it is a software fault?
I mean: did it ever occur to anyone? Is there really any hope that resetting my phone to stock will fix this?
I HATE having to reset my phone...
Thank you.
I stopped using custom roms a while ago because of minor problems that would suddenly appear.
I don't think there is a way to really tell if it is software or hardware unless you reset or use a stock ROM.

Well, that's a little hope at least.
I will need to find some time to re-stock my Nexus and try.
Thanks .
Ok, I restored the phone to stock and all sensors work again now!
Thanks audit13 for pushing me in that direction .
That's great that it was a software bug in the custom ROM.
Now you get to hunt for a custom ROM that works with a minimal or zero number of issues
