UA-cam channel PBKreviews has a teardown of this and he didn't have a problem removing the display after applying some heat - he didn't indicate how much heat but I would assume he would have mentioned if there was a major issue. However, TheHandyRetter channel did advise it needs a long time and to be careful.
I think the screen touch glitching at the start is an indicator that it was already faulty from factory, which might add to it just fully breaking when the phone was fully disassembled
The symptoms of the "dead" screen seem to indicate a lack of power to the OLED. Reason I say this is because the panel is extremely dim and seems to be dimmer the more pixels are active (thus the panel seems to be "off" when showing the lockscreen or certain dialogs during the setup)
Hugh, it seems as though the ambient light may be malfunctioning, the symptoms are very similar to a bad proximity sensor on an iOS device. was there maybe adhesive around it or is it possibly misaligned or disconnected after the full disassembly? I can see it’s below the front camera pressed through the mid frame?
Thought of the same thing, it might have had something to do with the proxysensor. Although the screen probably was sorta faulty in the beginning, he as said also probably burnt out all the pixels a lot by heating it so much
You can tell by the initial boot logo either the AMOLED itself or some power delivery problem is at hand. This is not an ambient light/proximity sensor 100% guaranteed.
It is possible if unlikely that the heat did end up damaging the screen itself. If the screen was still pretty warm when it was initially tested after having been removed it could have damaged something as it cooled down. From the sounds of it the screen got REALLY hot and it went through multiple hot/cold cycles which would expand and contract. You can also see the screen itself flex pretty hard while its being pried off the frame. All of that induces a lot of stress. Either way as noted if you are removing the screen its broken anyway but for it to be so difficult is a bad sign. I doubt it was intentional though.
This was my first thought too, either the excess heat and/or prying it off perhaps damaged something even though it briefly worked after Hugh quickly checked it before proceeding with the rest of the teardown. I suspect it's similar to a 'thermal shock' issue, therefore the cooling after the excess heating.
Maybe ambient light is malfunctioning, symptoms are very similar to a bad proximity sensor on an iphones. It's possibly misaligned or disconnected after the full disassembly
Most likely, though just a hunch, but it looks like the microcontroller board of the display got fried due to the heating process thereby messing up the connections. This scenario is similar to the Galaxy Note 9 yellow screen issue, where a software update causes the phone to heat up insignificantly during the recovery update which causes the chip on the display to be fried. The only way to fix is to replaced either the chip or the screen itself.
Look under the front camera, there is a hole in the screen. That hole is for all front facing sensors, even for screen brightness. The screen isn't close enough, too much light is going through that hole for the sensors. Try to push the top 1/3 with 2 finger down and see if you have better brightness.
update us to any developments with this. interested to see if this display would work on a different phone or if a different display would work on this one

@@r.Ry4N.05 Something could have broken during cooling. It's not always just excessive heat that can kill things, sometimes it's the cooling back down that gets it.
I think that like a lot of phones it's just supposed to be opened from the back, and to replace the screen I'd bet they'll sell the screen with the frame attached.
i work for a repair company. The google phones are designed to have screens replaced with the display only for easy screen repairs. More people break screens than they do housings / back glasses. They are not designed to be opened from the back on higher end google phones. The entire rear housing gets replaced on the top tier models. The lower tier ones have more repair features like being able to be opened from the back (only starting now with the 7a and on some older pixels). Realistically you shouldnt need to open them from the back unless the battery fails or motherboard, which are very intrusive repairs with pixels anyways. Most who break the back just put a case on it or live with it. Screen repairs that require full housings are very expensive compared to just displays. Take samsung devices for instance. 95% of them come with full housings with all buttons, a battery, and some small sensors like the fingerprint sensor. They are really expensive and make fixing a lot of older samsung devices not cost effective ( this is only true for samsung service centers / business with certified manufacturer repair contracts).
@@Lego455200930 did you not listen. The connector for the screen, is at the front. To disconnect the screen, get this, you have to open it from the front!
Hi there, the problem with the screen might be from the proximity sensor reattached incorrectly, that sensor considers that it's in a dark environment and it'll dim the screen near 0, I don't believe the screen it's faulty.
Great video Hugh, I just got mine and I'm loving it. My thoughts are that maybe all the heat did actually end up damaging some component in the screen. Because like you said it doesn't point to it being an anti repair maneuver by Google. Although it did seem to have problems since the beginning so maybe it was from a bad batch. I'd be curious to see if a screen replacement would bring this Pixel back to life, I suppose it's too much to ask for an update on that? Keep being awesome!
@@worthless_opinion Soft oled has superior image quality, but more than that the viewing angles are a dead giveaway, hard oled has a rainbow effect when viewing from an angle while soft oled is perfect from any angle.

Not at all. When a phone doesn't snap in half during the durability test, it usually still works after the teardown. It's not his fault manufacturers make crappy phones that snap in half.

I bought the Google pixel 7 pro with a damaged screen in one corner. I bought a replacement screen from eBay. I then removed the damaged screen with only a curved scalpel…no heat! The only bind being my big fingers attaching the screen ribbon cable. I had to move the finger print sensor, again with the scalpel. It was quite an easy replacement.
First of the redesign fully isn't copied from apple. Pixel 5a had everything from front screen, pixel 6a also had from the front screen but back side removable, pixel 7a now have screen from the front while rest of the things from the back. Secondly, what do you expect from this price range phone using hard oled? Flexible oled costs more and good only curved screens mainly. It also thin so can be use to save the space. But at this price range they had to cut the corners. 7 also use hard oled.
Just did one of these the other day. Its just as hard to remove front screen as its on fold 4 small front screen. I didn't know the back came off like that. Good to know. Now need to find out it 8 series does the same thing.
I have a silly question... It looks like the SIM tray was still in the device during most of the tear down, was the SIM tray still there the whole time?
It's called Cold Glue. Apple has been using it since iphone 6. All newer screens use cold glue to adhere the screen to the frame because it's more durable given how thin the bezel has become.

Great timing Hugh, I'm currently thinking about replacing my old Mate 20 Pro with Pixel 7a as I fell in love with Pixel UI. But something still holds me with Huawei and don't know what to do, I Wonder if it is just your phone faulty or it's something what afffects more of devices
I'd suggest looking at other teardowns and seeing if they experience similar issues. If they do and you want to spring for the pixel, maybe try the base 7.
Man, I'm in the same position. I'm still sticking with my Huawei Mate 20 Pro. It just works! The battery life is great and the screen is perfect even after all this years. Although, I've decided I'll definitely be changing it once the Pixel 8 Pro comes out!
Hey mate, I'm watching your videos now for a longer time now and I really enjoy it. I'm a computer scientist who's more in the software thing. But I also want to improve in hardware and also repairing, you're a big inspiration. Could you tell where do you get your broken devices from?
I’m a remote mobile tech for Asurion. I love when you can’t power down the iPhone 14 or 14plus because the display is too damaged, when the new screen is installed, I have to do a hard reboot back into customer UI, then power down and calibrate.
The exact same thing happened to my Galaxy S3. The display kept glitching the exact same way. After trying 2 new screens, it turns out it was one of the filters(small black component) next to the display connector.
I find it a bit strange how the one single small screw is right above the display ribbon, so its like google wanted you to put the wrong screw in the wrong hole to purposely cause damage, this is just childish and pathetic behaviour.
That happenned to my 5a last week. The screen went black out of the blue. For no reason. And I didnt take it apart nor had it on a hot plate. I can feel the phone vibrate and I can even hear it if I connect it to charge but no display whatsoever. And as I'm not in the US I'm SOL. 15 months the damn thing lasted.... Good work google. Thanks.
"there's nothing I did that would have damaged the screen" Huge, did you watch your own video? :'D remember when you had the phone on the heatplate for so long that, while heating the FRONT of the screen the BACK got hot enough to be disassembled from that side? lol
Try doing an incomplete FRP bypass. Skip the bootup process, go straight into the settings, turn on ADB and disable the OOBE for your user, then go into the launcher. Also put it at max brightness manually from settings. It simply doesn't make sense for the screen to cut out like that. It just doesn't feel right. It's too consistent. Plus, in the recovery is completely fine.
@5:39 I was pretty sure that batteries aren't manufactured that exactly, so I looked it up: +/-2.5% seems to be the standard tolerance (for industrial applications). That would be 110mAh. Therefore, 30mAh isn't really worth losing any words about.
Same. I had to have a Nexus 5 screen replaced under warranty and the other one the proximity sensor failed which meant I had to end phone calls with the power button. My Galaxy Nexus was perfect though and still works.
I had the exact same screen issue with my brother's Galaxy A71. Although the screen was never disassembled. It was able to show the boot screen and recovery menu but everything else was just black, touchscreen was still responsive tho.
The issue with touch inputs might suggest that the screen was defective from the factory so that might be the reason why it died after re-assembly? The heat could've speed up the process but not kill it immediately but as it cooled down the damage could spread... I dunno I'm just trying to figure out explanation because otherwise it doesn't make much sense.
My 5a has a black screen. It SEEMS the phone is working since I can feel the haptic feedback and hear the charging sound when connected but no image whatsoever. Not even in fastboot mode. Do you think it might be cpu as well? In my country its LITERALLY easier to get the bga chip reballed than it is to find pixel replacement parts and since i didnt get it here, googles extended warranty is meaningless to me... Could a cold solder joint on a cpu prevent the display from working but keep the phone "alive" otherwise?...
Hello, today we will make pixel soup. To make pixel soup, we need a Google pixel phone,a heat plate and optionally a pry tool. First off, pre heat the pixel phone at 500 Celsius for 4 minutes. Then, take your pry tool if you have it and open the phone. After that, remove the battery and camera modules. Then, take your camera less mess and bake it at 200 Celsius for 20 minutes, mix it up a bit, and you’re done! It tastes sorta like iron supplements.
Maybe the display doesn't like the long cooking befor the disassembly process. Yes it worked when was still hot but after cooling somthing probably disconnected internally and game over. Nice job google! P.s. im surprised the battery doesn't catch fire while cooking...
The display connector has a metal bracket and screw on top of it, this means you have to take the display out if you want to remove the motherboard you cannot otherwise, if the charging port is damaged you risk braking the display
I agree. I work in school IT tech support. We've had a large number of student Chromebooks and staff Lenovo laptops with USB-C ports get sent to e-waste/re-used for parts because the USB-C port is damaged and is soldered onto the motherboard. I know it is possible to de-solder the ports and install new ones, but we just don't have the tools, training, and most importantly, time. If the USB-C ports were modular, we could easily swap them out with new ones and reuse a lot of our devices.

I just got a Google Pixel 7, and I kinda wish I can just remove the back panel instead of the front. I rather not touch the front if I don't have to as it looked like you removed half the phone before removing the battery. If I ever need to do a battery replacement I don't know if I'd ever try to do it myself.
Can you try attaching a new battery and see if the display issue is fixed? Sometimes either the fault lies in the circuitry or the battery, (if the display itself is not short-circuited) due to which the display can't pull the required voltage to fully power the backlight.
You probably overheated the screen to some type of damage. In this video PBKreviews: "Google Pixel 7a Teardown Disassembly" screen go off normally. With one difference he disassembled other side first and then Display. But with no struggle.
I am 99% sure its something related to the proximity sensor, hope to see an update , while the screen is connected , lift it off the body to see if it resolves the issue. Or maybe there are pogo pins or something similar connecting the proximity sensor which arent well comnected.
Well, so much for my praising Google for their parts availability through iFixit. While you did get the screen off, I would not realistically call that procedure a practical proposition. Surely most experienced technicians would still end up breaking it and maybe damaging the frame as well. With a bad screen that may almost be acceptable but it just seems wrong.
Okay. I won't let my Pixel 7a screen sit on max heat for 10 minutes, get so hot that it burns me through a glove, and I'm confident that the screen won't "simply fail in a very strange way" Thanks for the tip...?
Would you be able to repair my Xiaomi Mi 11 Pro? It's been broken for months and it needs a replacement digitizer and screen. I can't do it myself, and no repair shops will take it.
I'm pretty sure Google is using true love to keep the screen togheter. That's why is so hard to separate it.
And some people say Google is an evil company, they use true love for their phones after all

In Aussie models they’re using 100% pure kangaroo spunk.

Get the 6, 6a or 6 Pro on the cheap, or maybe try a Honor or Xiaomi phone if they work in your country. Have you considered a Sony Xperia phone?
@@SayAhh the pixel 6 series so have some issues, so I'd recommend against them
Hey mate, I'm watching your videos now for a longer time now and I really enjoy it. I'm a computer scientist who's more in the software thing. But I also want to improve in hardware and also repairing, you're a big inspiration. Could you tell where do you get your broken devices from?
I’m a remote mobile tech for Asurion. I love when you can’t power down the iPhone 14 or 14plus because the display is too damaged, when the new screen is installed, I have to do a hard reboot back into customer UI, then power down and calibrate.
Hugh Jeffreys: Heats the screen at 500 degrees Celcius... The screen dies.
Surprised Pikachu face 😮
I wonder if the screen comes mounted to the frame as an assembly... not available separately, so not meant to be removed?
Looks at other teardowns of the 7A, the screen is supposed to come off, it just takes longer.
i prefer a plastic back over a glass one every day
The exact same thing happened to my Galaxy S3. The display kept glitching the exact same way. After trying 2 new screens, it turns out it was one of the filters(small black component) next to the display connector.
Every review praise this phone. But I feel this is the true review we need.
I find it a bit strange how the one single small screw is right above the display ribbon, so its like google wanted you to put the wrong screw in the wrong hole to purposely cause damage, this is just childish and pathetic behaviour.
Looks like Google used Gorilla glue on the display. 😂
That happenned to my 5a last week. The screen went black out of the blue. For no reason. And I didnt take it apart nor had it on a hot plate. I can feel the phone vibrate and I can even hear it if I connect it to charge but no display whatsoever. And as I'm not in the US I'm SOL. 15 months the damn thing lasted.... Good work google. Thanks.
That glue is similar what samsung use on their A series, It dry like rubber. It is way more secure.
"there's nothing I did that would have damaged the screen"
Huge, did you watch your own video? :'D remember when you had the phone on the heatplate for so long that, while heating the FRONT of the screen the BACK got hot enough to be disassembled from that side? lol
it might off been to much heat on the screen
Try doing an incomplete FRP bypass. Skip the bootup process, go straight into the settings, turn on ADB and disable the OOBE for your user, then go into the launcher.
Also put it at max brightness manually from settings.
It simply doesn't make sense for the screen to cut out like that. It just doesn't feel right. It's too consistent.
Plus, in the recovery is completely fine.
oled needs more current when showing bright colors, the phone's fine with powering lower amount of pixels but fails when there's too many
You should disconnect the battery before the screen. You may blow screen back light filter
OLED doesn't have backlight?
Hugh remember you finding a gap from the earpiece? Maybe that’s when you damaged the ambient light sensor.
@5:39 I was pretty sure that batteries aren't manufactured that exactly, so I looked it up: +/-2.5% seems to be the standard tolerance (for industrial applications). That would be 110mAh. Therefore, 30mAh isn't really worth losing any words about.
Am impressed by the firmness of the screen
Having bought almost every Google Nexus phones, I will always be suspicious of Google's quality control for its hardware.
Same. I had to have a Nexus 5 screen replaced under warranty and the other one the proximity sensor failed which meant I had to end phone calls with the power button. My Galaxy Nexus was perfect though and still works.
I had the exact same screen issue with my brother's Galaxy A71. Although the screen was never disassembled. It was able to show the boot screen and recovery menu but everything else was just black, touchscreen was still responsive tho.
maybe it was some kind of epoxy holding the screen in place?
It's like the biscuits I made this morning...overcooked.
Thank you Hugh for this video.
The issue with touch inputs might suggest that the screen was defective from the factory so that might be the reason why it died after re-assembly?
The heat could've speed up the process but not kill it immediately but as it cooled down the damage could spread... I dunno I'm just trying to figure out explanation because otherwise it doesn't make much sense.
YES! I have a P7A that also has a bad screen, exipiting the exact same symptoms. Google has a serious quality control issue.
i have built and repaird stuff in the past but i have never had anything to fail like that that is very cool tho
2:54 ish area. You can definitely tell this is a hard OLED display
And that's why I have the "old" 6a
9:03 This sounds an awful like the behavior of an Android device with a bga chip that has cracked solder, especially if it's the CPU
My 5a has a black screen. It SEEMS the phone is working since I can feel the haptic feedback and hear the charging sound when connected but no image whatsoever. Not even in fastboot mode. Do you think it might be cpu as well? In my country its LITERALLY easier to get the bga chip reballed than it is to find pixel replacement parts and since i didnt get it here, googles extended warranty is meaningless to me... Could a cold solder joint on a cpu prevent the display from working but keep the phone "alive" otherwise?...
this proves we're a step closer to laser machining screens just for the glue to let go
hey important question, where do you buy your tech lots??
Hugh,
Pardon my ignorance, but could the extra heating have caused the screen to fail?
Hello, today we will make pixel soup. To make pixel soup, we need a Google pixel phone,a heat plate and optionally a pry tool. First off, pre heat the pixel phone at 500 Celsius for 4 minutes. Then, take your pry tool if you have it and open the phone. After that, remove the battery and camera modules. Then, take your camera less mess and bake it at 200 Celsius for 20 minutes, mix it up a bit, and you’re done! It tastes sorta like iron supplements.
Maybe a new front screen part will always come with the frame? There-by forcing shops to move all the internals into a new frame?

Did you try turning off autobrightness?
Pretty Hard job Google 🎉
Maybe the display doesn't like the long cooking befor the disassembly process. Yes it worked when was still hot but after cooling somthing probably disconnected internally and game over. Nice job google!
P.s. im surprised the battery doesn't catch fire while cooking...
The display connector has a metal bracket and screw on top of it, this means you have to take the display out if you want to remove the motherboard you cannot otherwise, if the charging port is damaged you risk braking the display
Hey Jerry rig everything's channel did the disassemble and reassemble with no issues at all
Would you do the Pixel Tablet or the Pixel Fold as they were announced as well?
Probably a faulty screen from the factory, heating it to 120°c for 10 minutes was probably the last nail in the coffin
You disconnected the screen before the battery, why?
Wtf that soldered usbc port. Thanks for your help!
Hard soldered charging ports on the motherboard should be illegal
what’s the problem with it?
@@shadowhejhog because charging ports are prone to failure pretty easily.
They wear out quick(er), depending on your use of it
I agree. I work in school IT tech support. We've had a large number of student Chromebooks and staff Lenovo laptops with USB-C ports get sent to e-waste/re-used for parts because the USB-C port is damaged and is soldered onto the motherboard. I know it is possible to de-solder the ports and install new ones, but we just don't have the tools, training, and most importantly, time. If the USB-C ports were modular, we could easily swap them out with new ones and reuse a lot of our devices.
@@JJFlores197 I once try to replace my old samsung(I think its samsung, i dont really remember) cahrging port. Its only micro usb 2.0 so it have less pin than new phone today. It took me 4h but I got it working.
I dont want to do it again. Especially without proper tool
Thanks a lot for this video. I was looking for a new contract with a new phone, but it seems I'm keeping my OnePlus 7 Pro for some more years.
That display was wonky to begin with!! Google get this man a new screen and stop using super glue on your screens!!
The screen was having issues before you even opened the phone
I just got a Google Pixel 7, and I kinda wish I can just remove the back panel instead of the front. I rather not touch the front if I don't have to as it looked like you removed half the phone before removing the battery. If I ever need to do a battery replacement I don't know if I'd ever try to do it myself.
Great video, just wish you would've gone more indepth on why the screen is screwed up. Definitely won't be getting a pixel a
Can you try attaching a new battery and see if the display issue is fixed? Sometimes either the fault lies in the circuitry or the battery, (if the display itself is not short-circuited) due to which the display can't pull the required voltage to fully power the backlight.
Hi, what glue should I use to glue the back panel back?
You probably overheated the screen to some type of damage. In this video PBKreviews: "Google Pixel 7a Teardown Disassembly" screen go off normally. With one difference he disassembled other side first and then Display. But with no struggle.
I saw other channels succeed in reconnecting the screen
Can't wait for follow up video lol
I am 99% sure its something related to the proximity sensor, hope to see an update , while the screen is connected , lift it off the body to see if it resolves the issue.
Or maybe there are pogo pins or something similar connecting the proximity sensor which arent well comnected.
Well, so much for my praising Google for their parts availability through iFixit. While you did get the screen off, I would not realistically call that procedure a practical proposition. Surely most experienced technicians would still end up breaking it and maybe damaging the frame as well. With a bad screen that may almost be acceptable but it just seems wrong.
Okay. I won't let my Pixel 7a screen sit on max heat for 10 minutes, get so hot that it burns me through a glove, and I'm confident that the screen won't "simply fail in a very strange way"
Thanks for the tip...?
Tell that to my 5a...
That front was probably vacuum sealed 🤣
Would you be able to repair my Xiaomi Mi 11 Pro? It's been broken for months and it needs a replacement digitizer and screen. I can't do it myself, and no repair shops will take it.
do u will ever brokled it .? ,
