Phone screen flashes once when unlocking - Google Pixel 4 Questions & Answers

Hi,
I have a Pixel 4 on A12. Everything was going well without issue til a few days ago.
I realize my phone will flash once white light after I unlock the phone.
Is this normal for Pixel 4? I read some other place that it is software issue, anyone has any experience with this?
Thank you

Dead pixel on hermes

Hi everyone I am wondering if anyone here have 1 or 2 dead pixel on their hermes? I recently have 2 hermes one is a TyTN "HT630" and one is a X01HT "HT638" and the TyTN has a alignment problem and the X01HT has one dead pixel on the screen......Thanks for anyone's advice!!
I don't have a dead pixel and only have to align the screen every second week I think.
But sometimes I have to press the "d"-key a bit stronger than the others.
I bought new X01HT here in Tokyo on Monday, and it had dead pixel in the middle of the screen, pink - very ugly one... They said it can be repaired, so I had to leave them the phone (since there are no more X01HTs left, all sold out...). Now I'm waiting for the device, very inpatiently...
I wonder how they fix a dead pixel except for changing the LCD?
I'm sure they will replace the LCD.
Of course they will change it... (The display, not the pixel) At least I hope they will...
oh well I guess I cannot do anything about my dead pixel on my X01HT since is all unlocked and flashed so no warranty =D
That's why I hesitated to unlock it when I got it. I had it only for one day before I submited it to the service. But I have one big fear, they might update it to new unlokable bootloader / radio, and then I'll not be able to do anything good... Hope they will not play smart-ass...
Thats true.....because usually you drop in a phone and they will flash it to the newest firmware......just hope that the 1.09 can also be unlock soon! =)
p.s. I just run some stuck pixel fix videos for hours on my X01HT but no luck =(

It is technically not possible to fix a dead pixel by playing a video!
Sometimes tapping your finger on the stuck pixel many times can get it moving again. I've seen this on a LCD tv.
I am trying to do that too buy no luck =(
I actually fixed a few stuck pixel (not dead but just stuck to a few colors) on a PSP by playing those videos.....but I don't know about the hermes....oh well I still rather stuck with my little stuck pixel on the X01HT then I have to align my screen every 5 minutes with my old TyTN before! =D

annoying flickering and/or flashing

I'm having a very frustrating problem with my Nexus 7 (2013). About a week ago I started to notice the screen flickering and or flashing. I uploaded a video to show exactly what it's doing. I have tried to research and the only workarounds I found were to disable auto brightness and wi-fi optimization but both have been ineffective in solving the problem. The Nexus is currently running this kernel (razor-jss15q-factory) and was purchased around release day.

I have a flickering problem but it looks different than yours. Also my screen occasionally flashes black. I've also tried all the auto-brightness and WiFi tricks to no avail. The problem persists no matter what brightness my device is at and across multiple roms. I'm just about ready to send it back to ASUS for a replacement.
The flicker to black is not normal. Slight flicker at low brightness, more units have.

And you should return it. Flickering seems to be 'normal', going black is not

If JSS15Q or JSS15R doesn't fix it, I would return or exchange.
I returned the tablet to ASUS. After a 2 week turnaround time (including shipping both ways), I fired it up and immediately noticed the exact same problem (random flashing to black, plus some minor flickering). I called up ASUS again and inquired as to what they had "fixed". I was told by the customer service rep that they simply did a factory reset. They could offer no explanation why this was the only thing done.
So, back to ASUS it goes, again. This is frustrating.

Pink Lines on Screen

Wondering if anyone else has run into this issue. The other day I noticed that in apps with a white background color, I would have horizontal pink lines on the screen, sometimes vertical, too. It drove me crazy enough that I went to the Samsung service center close to where I live, and the guy flat out just told me that the screen needed to be replaced. I didn't leave the phone with them because I kind of need it, but I will have to eventually.
Weird thing is that there are no dead pixels - all the pixels are fine and went through the pixel test with no issues.
Anyone else experiencing this? Pretty frustrating since I got the phone less than 2 months ago.

Hey I think I might be having a similar problem, it started to happen yesterday and about a third of my phone is now constantly turning pink. If your problem is like the one below then let me know and I'll keep you informed in what Samsung say when I contact them later today
Just realised I can't post links yet but the images are here imgur(dot)com/a/YBA5o
Same thing started happening to me a few hours ago.
Definitely a hardware fault.
Mine was purple smudges and washed out, sent out they replaced the phone, its a hardware/factory defect.
Yeah definitely a hardware problem. I took a screenshot of the pink and sent it to my computer so I could view it there, and the screenshot was absolutely fine and pink free on my computer, so yeah, hardware problem like the people at Samsung said.
Just sucks that I can't get a replacement unit because I am over the 30 day period. That is just bull**** if you ask me. The phone is still brand new and doesn't even have a hairline scratch on it.
Sorry to necro this thread but the same thing happened to me again, after the screen was replaced the first time. Now it's gone in for a second time. I think this is a pretty well known issue with certain S7 Edge productions. Really even scared of the Note 7 now because I believe it's happening because of the edge panel.
2nd phone with the same issue, 1st time they replaced the phone for brand new, now the same problem... it happens only on s7 edge duo?
Past 31st I bought the S7edge black pearl version. When the Samsung sales executive unboxed and switch on those pink lines were displaying. I was shocked to see those. Immediately they asked me to wait and replaced a new one. I waited for an hour there and browsed my phone completely so that there will no major disappointment.
Just shared this incident on seeing this thread.

sam**** at its best again!
after note 7 failure they dont even care about this as they also updat bugs in 1+ old premium non premium devices :/ and then they launch new devices with smooth OS and higher price tag!
i had NOTE 4 EDGE from last 1 year. recently i saw a green line on my edge panel and after a day it disappeared. i sold out my note edge! em not gonna buy any sam**** device again to $900 !!!!! the lines on screen issues are common in note 4, note 4 edge, S6, S6 edge and now S7 EDGE :/ just to sell more note 5 and note 7 but both faild
now its s7 edge turn to face these all bugs!!!!! cox S8 coming! RIP

Think I'm boned, figured I'd ask anyways...

So I think my 6P screen just up and died, completely out of the blue. I was using it minutes earlier no different than I usually do and it wasn't dropped or exposed to liquid, etc.
So the phone was charging and the battery light was on so I know it was powered on. I went to wake the device and was unable to. The screen VERY QUICKLY flashes like it's trying to turn on and then turns back off right away. Only the middle of the screen attempts to light up. I can actually see a brief flash of my notifications on my lock screen. I figured it might just be a hiccup and force powered down the phone by holding power. I tried to boot it again and still no screen, nothing is happening. Eventually the battery light comes on, so I know it's booting up.
I was able to use ADB to backup my files and reboot to bootloader and used fastboot to flash factory images. Sadly, the issue persists. Phone is long past both Google and Huawei warranty programs. RMA doesn't seem to be an option. I'll be fixing this myself.
I guess my questions to anyone with insight are;
-Has anyone else ever ran into this and managed to fix it? Unlikely, but hey...
-Does this sound more like a display issue or a motherboard issue? Or something else entirely? This being my primary question, really, as it matters for which parts I'm going to have to buy. I would guess the motherboard since the display wasn't dropped or exposed to liquid/fire/heat/cold/explosions/radiation/alien probing/12 rounds with Rocky Balboa/etc., and it still makes an attempt to turn on. If it was the MB, would it even boot? IDK, that's why I'm asking.
-Any reputable vendors which sell quality parts for the 6P? I've had hit or miss experiences with phone parts in the past and I haven't taken anything apart since my N5 & GNex.
Thanks for any help you can offer.
Maybe the solder is bad could try 200 degree oven for 10 minutes to see if it that fixes it?

Possible, I suppose. Thanks! I'll give that a shot as a last ditch effort. I called Google just to see if they'd RMA it, told me I was out of warranty which I knew was the case. They were getting transferred to Huawei for a conference call with Google and them and Huawei disconnected. The Google rep said Huawei has actually been surprisingly good about taking care of certain out of warranty issues. 30 minutes on hold with them, we'll see how it goes.
I think that's a possibility since the screen keeps doing weird things. Blinks on for a half second on the top right of the screen, then the left, the middle, the bottom. Touch absolutely works across the entire display even though nothing shows. I was able to guesstimate the encryption pin entry to finish booting which allowed me to ADB pull all of my files (silver lining, I guess). It vibrates when I touch it, etc. If the oven trick doesn't work I'll just solder it myself and see if that fixes. That would be nice if I didn't have to buy anything!
I think Huawei is putting up a front to Google to look like they are doing good but lots of bad reviews on the forum glad I paid for the warranty first time and only time I've had to use it twice so far this last time they sent me a refurbished phone wonder how long I can do this for this may be the last phone I will actually want

Thanks again for the input, could you do me one last favor anytime you get a chance? From the bootloader, what's the key combo to power off the phone? I just want to turn it off. I can power to the bootloader, but I can't remember the key combo to POWER OFF. I know 6P has some others like barcodes, etc. Not sure if it's up twice, down once, etc. If you can't no biggie, I guess it can sit at the BL until the battery is dead dead.
If it started on start it should be three down

If you have an Amazon Firestick or a Chromecast does it show up as an option under screen mirroring? I believe if the cpu and gpu can render the image for screen mirroring, then you know the display is bad or the connector needs to be reseated. What do you think? Edit- but you would need to enable wireless display for that it's early, I will keep thinking of ways to narrow it down. The voice command open display settings will get you halfway there.
Or have a look at this. The only trick will be finding the touch area to allow the adb key. http://www.techrepublic.com/article/pro-tip-mirror-your-android-device-on-your-pc-with-ease/

Sounds exactly like my screen failure.
One minute working, reboot. Dead.
I had to get a warranty replacement. (Nexus Protect $79.)

Did you purchase directly from Google? I've had my 5X since 2015 and it entered an endless bootloop last week. Gave Google a call and they offered me a one time warranty replacement because I'm in good standing and long time user of Google Play products. Worth a shot?

Not directly from Google Play. It was pre-ordered from Project Fi. When I called Google support about it, they transferred me to Fi which said they'd have to transfer me to the manufacturer, Huawei. They told me there was nothing they could do, call a local repair shop. I called a place in town and he offered to take it apart for me and try to reseat all of the connections and if it started working he wouldn't charge me. Otherwise a replacement would be $200 :/
I'm taking it there tomorrow so hopefully it's just a loose connection and starts working again. Touch seems to work fine all over and I cleaned the screen and put a light on it just to make sure there wasn't any cracks I didn't know about. Looks fine. I'm optimistic, lol. I think $200 is kind of steep, but he said it also comes with a lifetime warranty, so I guess that helps ease the pain a little. I need it fixed ASAP though. My backup Nexus 5s battery is shot. Takes like 12 hours to fully charge and discharges in about 2-3 hours.

Screen lines and unlocking static

So over the last few months I've developed issues where my screen will randomly get a few lines here and there after unlocking or rebooting, but nothing major, until today... After a reboot it's happened the worst I've ever seen it and it's worrying me now, I'm hoping someone can give me an idea if it's the lcd going bad or something else since I've never experienced this with a phone before, I know it's hardware because it doesn't show up in screen shots. Though it always goes away after another reboot. (for now)
Ive also started noticing when unlocking the screen theres a few milliseconds of static(or "noise") like a TV without cable.
I have a battery coming so I will be opening it up in the next few weeks and I'm hoping that's not gonna make things worse, but who knows it could fix it. I think I would be willing to put the effort into a lcd replacement if it's necessary. Any input would be appreciated and thanks in advance.
This is like typical moto x style bug or hw issue, static after unlock and different screen artefacts are common on this model. https://www.androidauthority.com/moto-x-pure-display-driver-issue-687393/ They never fixed this, it's still there on 7.0. It can look in many different ways, I've seen few on mine like white stripes, washout colors or half broken dispaly and it always goes away after reboot. The only penament fix is to sell/throw away this crap and never buy motorola again xd

Ah, I wasn't really expecting it to be a normal thing. I will say the issues I have with this phone seem to be consistent with everyone else. But unfortunately this is "crap" is actually the longest lasting phone I've ever had sadly, but I definitely feel I've got my money's worth out of it.
Thanks for the reply.
