[Q] Just a weird screen flicker, normal? - Nexus 4 Q&A, Help & Troubleshooting

I've had my phone since end of November so its one of the original rev.
Just a few minutes ago I rebooted my phone to recovery and this is what happened.
- Rebooted to Recovery (TWRP)
- Screen turned White
- Didn't do anything and went to take a picture of it.
- Took a Picture (view below)
- Then it loaded TWRP but screen is still flickering
- Didn't touch anything and it went to the bootloader menu and screen was still flickering.
What I mean about flickering, the screen was still viewable just the brightness was going higher and lower.
- Rebooted back to System (still flickering), tried to record it but couldnt really since the quality of the cam couldn't see what was going on.
- Rebooted back to TWRP, loaded it fine but still flickering.
- Rebooted back to System and it went away.
- Rebooted back to TWRP and it looks fine.
Modem: .83
OS: 4.3
ROM: Paranoid Android 4.3 August 16
Kernel: hells-Core b33-ANY
Now someone might say oh its the kernel, probably kernel or ROM. But this happened in both the bootloader menu and TWRP and during that time ROM and kernel wouldn't be running.
Anyone has had this happen, please share your experience
Wanted to know if this is a known thing or my phone is starting to die?
Only dropped once like 6 months back and thats w/ a hard case on.

Happened to me twice till now. I think it's just a bug with gpu and a reboot should fix that. Although, I have no clue why it happens or what triggers it. Also I have noticed that both the times it happened to me, I was rebooting into recovery (TWRP).

Ah alright thanks, good to know I'm not the only one or at least its known.
I practically flash my phone weekly/daily and never had that happen to me before so when I did it today I was like wth lol. Now with my experiences with computers when it something flickers like that or graphic errors we think drivers and if its not loaded up we think its memory dying so I was already trying to diagnose it lol..
But if its a known issue guess I cant do anything about it, at least its back in working condition :good:

The same thing has happened to me, but when I am running Google Maps. The first time it happened the screen became unresponsive and I went to reboot and had the same flashing screen you are describing. I started freaking out and went to reboot again and it was persistent in the boot screen each time. After about 5 minutes it stopped but I still have issues with my phone freezing with Maps and now when I look at flash videos on the stock Browser (I don't use Chrome).
I had a similar issue with my Macbook Pro when I accidentally block the exhaust but my phone is set to very lore frequency's with SetCPU.
I am using AOKP Milestone 2 and Ziddy's kernel for OTG support.

Factory reset didn't work, I will try reflashing and see what will happen
I had the same issue when i was installing wrong CF root. Check if the root is for your firmware version

I think the problem wasn't from the root because i rooted the phone after upgrading to froyo and this was from a month ago, but this problem suddenly happened after i restarted the phone yesterday.
I flashed the new 2.2.1 firmware and the problem solved
but now vibration doesn't work
and it doesn't have arabic lang. so i can't read anything written in arabic.
I think i will flash 2.2 back again, but the new firmware is very fast and everything runs so smooth, no need to lagfix.
I know the answer! The battery icon mod with the percentage is not correct for your firmware.
It happened to me before when I tried to put the jpo battery mod on the official italian jp5 fw and also if I try to mod the battery icon of the latest jpu.
It's a problem due to messing up the framework-res.apk file.
So, revert back the battery mod to the original icon and everything will work again.

[Q] Display Glitch on CyanogenMod M10 and Onwards.

Sept 20
I've been getting a display bug while using the Cyanogen M10 snapshot and I can't figure out the issue.

I have done a fresh install, no kernels, no messing with stock performance settings, and lately no Xposed. Disabling Xposed seemed to have no resolve with the issue so I've tried a dirty flash this time to see if it could be something that messed up system files.
Anyone know what might be causing this or be suffering from the same issue?
In addition I tried doing a reflash of the ROM after having determined Xposed is not at fault (issue persists), this is me testing to see if some system files are somehow corrupt and have done something to cause this.
Sept 21
I noticed that the issue commonly occurs while I am in the middle of typing with the keyboard, cleared cache & data of Google Keyboard.
I have installed the latest Nightly in an attempt to fix this, if it is an issue with the M10 Snapshot.
Time since boot: About 4 hours. (Trying to find a correlation).
Issue persisting.. kinda?
The screen flashes the glitch this time, rather than freezing with the screen. So think of using some sort of app or interacting and for a split second the above image, or something similar, appears then reverts to proper rendering. My phone froze not too long after this, I didn't sit and wait to figure out if it was lag or full-freeze.
The display stopped responding though the keys still would re-light after touching the home key. I waited only 10 seconds before pulling the battery, since it wasn't worth the time finding out.
P.S. I have also posted this in the CyanogenMod Builder Thread, so if it looks familiar.. there you go.

did you Wipe completely and then install fresh rom?
1. wipe completely through recovery (cache/dalvik/data)
2. install Fresh (latest nightlies) firmware
> if problem remains after few hours (without any extra customization) it might be the hardware problem... so take it to a services.
:good:
I have done those entirely.

Wifi not turning on after unlocking

I was running 7.1.1 when i unlocked my Nexus 6P.
After it wiped and rebooted, i could not see any wifi networks.
I went to sleep and wifi appeared to work in the morning but stopped again and i could not see any wifi networks around me.
i left beta program and went back to 7.0 (NBD90X), wiped and rebooted. same problem. but wifi did appear at one point but stopped again.
when look at the settings. it says wifi disabled. i click on the wifi settings, it just hangs at "Turning wi-fi on...)".
i have since, loaded TWRP and rooted. same effect on wifi.
any suggestions?

Maybe you can try this way : settings - location - scanning(Upper right corner) - turn off wifi scanning.
My English is not good, but I am willing to be patient to help you.
thank you for your help. turning off scanning did not have an immediate effect.
again this morning, it was working but stopped a short time ago. when i try to turn WiFi on, it feels like it is just hanging and can't start fully.

i completely removed root and locked the phone and still no ability to see WiFi at all.
Dont know if this will help you, but I was having the same problem with my tablet. I flashed everything back to stock and then rooted, flashed latest TWRP , and ROM and the problem was resolved.
I ended up just claiming a warranty on it after it wouldn't work with stock ROM and updates.
Thanks!

Need help troubleshooting, ROMs are not working properly, no comms, etc.

I am in dire help with troubleshooting my Axon 7 (US variant).
Here's some quick info on what I have done with the phone.
-Unlocked bootloader
-Tried out the CM ROM, and then flashed a stock based ROM (wiped all the stuff I needed too)
-It's been working fine since then
Fast forward to today. I wanted to try out some more ROMs. I wiped what I was supposed to (Dalvik/Art, cache, data), flashed the ROM, set it up, everything worked fine. Only thing that didn't work was that it wasn't downloading my previous Play Store, so I rebooted a few times, didn't fix it, so I wiped the phone again and reinstalled the ROM. Now here's where things to get messed up.
-Booted into the ROM and no comms are working (ex. SIM data, WiFi)
-Phone kept rebooting roughly every minute
-After a few reboots, the right half of the screen would freeze
Wiped and reflashed a couple different ROMs, same exact things are happening. Okay, this is weird, so I restored my backup (I ticked to back up everything in TWRP), and the same things are happening in my backup now. It doesn't matter what ROM I try, if I wipe the SD card, or even format it, the same things keep happening. I have trying to troubleshoot for the last few hours myself with no success.
Does anybody know what's wrong and any way I can fix this?

Have you checked to see if you still have imei number. Sounds like you may have wiped/lost it.
Check about phone>status>imei should have one for each sim slot.
If you do still have both then factory reset, and flash drakken’s b29 update files the bootstack,etc then his stockish rom. Should get you back up and running

anyone having the same issue?
Hopefully this gets a bump up. I've been having this issue as well. tried doing a factory reset but to no avail.
ACCELEROMETER and GYROSCOPE are constant even with the phone moving..
I'm having the same issue. It started after I got the Oreo update so I reverted back through Odin to nougat and it still had to issue.
I'm having the exact same issue with my S8 SM-G950F. I don't think its the software. Ive done factory resets and got the official OTA update to Oreo and the problem persists.
I had the same issue on my S8 Active. After reflashing it and having it looked at the only fix was to replace the phone.
I had not damaged the phone in any way physically so I thought it was the Oreo update but maybe not. They had no clue why it happened.
S8 all sensors not working except face recognition and fingerprint
i have the same EXACT issue. ALL the sensors are not working, except the fingerprint. has anyone out there fixed their s8's sensor problems? please i need help/advice. mine started having these sensor problems this month 22 June 2018.
my s8 will be 6 month old this 29th of june 2018.
i have tried
- rebooting
-resetting
-restore factory
-updating all apps (OS updated as well)
-clear cache
-uninstalled apps
model - SM-G950FD
exynos
Experiencing the same problem
Having the same issue, most of my sensors are not working gyroscope, pedometer, heart rate sensors..
Any one solved it yet???
