Segui questa guida per sostituire lo schermo rotto o danneggiato di un Pixel 4a.
Il pannello del display, privo di rinforzi, nel Pixel 4a è fragile. Fai particolarmente attenzione agli avvertimenti durante la procedura di smontaggio se per qualche motivo devi riutilizzare lo stesso schermo.
Cosa ti serve
-
-
Nota i due livelli di giunzione sui bordi del telefono:
-
Giunzione dello schermo: un dislivello separa lo schermo dal resto del telefono. La sezione su cui far leva è questa
-
Giunzione del frame: qui un frame di plastica si congiunge con la cover posteriore: Non fare leva su questa giunzione
-
Prima di iniziare, nota le seguenti zone dello schermo:
-
Cavo flex del display: Non inserire il plettro più a fondo di quanto indicato per non rischiare di danneggiare questo cavo.
-
Perimetro dell’adesivo: far leva oltre questo stretto margine senza angolare il plettro rischia di danneggiare il pannello OLED.
-
-
-
Posiziona un iOpener riscaldato sul lato destro del display, per un minuto, in modo da ammorbidire l’adesivo.
-
-
-
Posiziona una ventosa il più possibile vicino al bordo destro dello schermo.
-
Solleva la ventosa, applicando una forza costante.
-
Inserisci la punta di un plettro all’interno della giunzione dello schermo per non più di 1mm.
It's pretty easy. Insert it just below the screen between the Display and the Display “holder” or mold.
-
-
-
Mentre il plettro si trova 1 mm all’interno della fessura, sollevalo verso l’alto in modo da formare un angolazione abbastanza elevato.
-
Raggiunta l'angolazione elevata, spingi attentamente il plettro nella fessura per circa 6 mm. Il plettro dovrebbe scivolare al di sotto del pannello OLED.
This took me a while, I ended up sharpening the tip of the pick with a razor so I could push it through the seam and slicing a few times, heat->sharpen-> slice until I finally got it to move, and once it slid under carefully heated up areas and sliced with ~2mm of the pick.
This sounds also harder than it is. Push it in 1mm and just lift the other end in a wider angle like 70° degree from the horinzontal position. There “shouldn't” be much you can do wrong. Because except for the Data cable (flex) at a certain position, I can't remeber anything important but isolating tapes that I have scratched.
It's just the Screen glued to the mold. That's it.
Oh, and I wonder here where do You all get such thins plectrums? I have also the flat plastic version and the thin plastic cards but none of them were thin enough for this!!
I ended up using the backside i.e. the dull side of a Razorblade. I didn't saw any alternatives to this. Did You hear this OP?
Any!!
the display flex is directly on the bottom of the phone. BE VERY CAREFUL when going around the bottom to not hit the display flex!!!
-
-
-
Fai scorrere il plettro lungo il lato destro dello schermo per rimuovere l’adesivo.
-
Lascia il plettro sull’angolo in alto a destra dello schermo per impedire che l’adesivo faccia presa di nuovo.
The display flex is directly on the bottom of the phone. Be very careful when goign around the bottom to not hit the display flex!!!
-
-
-
-
Inserisci un altro plettro di apertura in un angolo sul lato inferiore del telefono, dove si sarà formata un'altra fessura, in modo da evitare di danneggiare il pannello OLED.
-
Fai scorrere il plettro lungo il lato inferiore del telefono per tagliare l’adesivo.
-
Lascia il plettro inserito lungo il lato inferiore per evitare che l’adesivo faccia nuovamente presa.
Top and bottom edge adhesive were much stronger than this suggests. Corners were very hard to detach. I killed my screen b/c I cracked it at the top. Worked better with heating around whole perimeter like an iPhone.
WARNING: Be very careful prying the bottom left and right corners! In fact do not insert anything there because there is only a 0.8mm clearance between the screen and the edge, and there's a 0.5mm space between the screen and front glass where if you insert a pick between the screen will crack and break! I had to replace the screen after only doing a battery repair...
Unfortunately I did not properly read the comments here. So for the unafraid people like me:
DO NOT insert something into the bottom right! Especially not like it is shown in the image at this location!
Instead I suggest start releasing the screen from right, then left side, then top and as the last step release the bottom, but start with the left corner. Do not pry too much and use a bit more heat as suggested.
There is a small image of this critical right corner in Step 16 (the part at the top is the display and the left corner at the top is the critical right corner here). You'll see the orange cable in the corner which is easy to damage...
I can second the warnings - especially at the lower corners the OLED screen is extremely sensitive to breaking - as has happened in my attempt when inserting the pick 2 mm.
The display flex is directly on the bottom of the phone. Be very careful when goign around the bottom to not hit the display flex!!!
Unfortunately despite being very delicate on the bottom right corner I ripped off a tiny bit of the digitizer cable and that resulted in a not working screen... went from spending 50€ for a battery replacement to a 150€ total expense battery + screen... :-( My advice is to not even pry the bottom corner, pry all around, then apply heat carefully until the screen is detaching.

C'è una griglia che copre la capsula auricolare sotto il bordo superiore dello schermo. Se non hai una griglia di ricambio, stai attento a non danneggiarla o perderla.

Solleva lo schermo dal lato superiore e fallo girare attorno al lato inferiore, finché non riesci a poggiarlo con il vetro rivolto verso il basso.
FR : Précision : La nappe a un bout d'adhésif sur la structure du téléphone, il faut bien faire attention de le décoller. Je viens de tuer la nappe de mon écran qui était fonctionnel...
EN : Advice : The ribbon cable is fixed to the structure with a small piece of adhesive. It should be remove prior to anything else. I just killed the ribbon cable of my perfectly used to work screen...

-
Con un paio di pinzette, rimuovi delicatamente il nastro isolante che copre la staffa sopra il connettore dello schermo.
Interestingly this tape was missing in my phone. Maybe that explains some of the display issues I occasionally had, like a thin green line on the right side of the screen which could be "pushed" away.
I think I ripped off the cable because it is undistinguishable from the tape! How screwed am I?
-
-
-
Usa un cacciavite Torx T3 per rimuovere le due viti da 2.1 mm che tengono in posizione la staffa sopra il connettore dello schermo.
A T4 driver worked for me here.
It is definitely a T4.
Funny ... For me, it was T3. The screws must vary across different phones
-
-
-
Usa la punta di uno spudger per fare leva sul cavo flex e disconnetterlo.
No, why the tip? Use the other flat side that doesn't concetrate all the power on one point and Youre doing a propper job.
Only the tip is needed to lift a bit one of the sides and it will pop out. No pressure/power!
-
-
-
Rimuovi lo schermo.
-
Verifica se il tuo nuovo schermo di ricambio ha la griglia degli altoparlanti e l'adesivo sul bordo superiore preinstallati.
-
In tal caso, non avrai bisogno dell'adesivo sul bordo superiore.
-
Se non ce l'ha, rimuovi il rivestimento trasparente più grande dall'adesivo sul bordo superiore e applicalo allo schermo (non alla cornice). Assicurati che l'apertura più grande si allinei con la griglia degli altoparlanti.
-
Segui questa guida se stai usando adesivi ritagliati su misura.
This step seems to imply that a screen replacement is necessary when replacing the charging port. Is the charging port replaceable without replacing the screen? I understand great care must be taken not to damage the original screen in the procedure, but can it be reinstalled?
Yes, it can be reinstalled.
Just a heads up: If you are like me and you have accidentally turned on your Pixel 4a at some point while trying to pry the screen, don't worry too much. I was able to just connect my display with the device on. Nothing will happen until you reboot, and then the screen will initialize.
It would help to add that the new screen is reattached after adding glue to phone body, not the screen. With the iFixit screen adhesive pieces, a guide to which piece goes where would help also. For that I used this picture: Google Pixel 4a Display Adhesive - Genuine. Yet that is not enough as there is a cover for (speaker?) which is not clear how to apply that.
The repair kit comes with Google Pixel 4a Display Adhesive - Genuine but there is no guide on how to apply that adhesive. I sent an email, but Ifixit won't make an instruction page for this.
To explain how the adhesive sold by iFixit works, the actual adhesive is the black strip which is held between two pieces of plastic. Line up the pieces with the clear plastic side down. Note that some pieces may be stuck in the box they came in, the plastic is staticky. I recommend that before attaching the new screen you put each piece in place. Remove the clear plastic and place the pieces in place with the colored plastic facing up. The goal is to have the black adhesive strip on the little ledge between the edge and the depression inside the phone. It's the place where you hopefully spent time cleaning out the original adhesive. Place the corners first, then the edges. Press them into place carefully. Before removing the colored plastic attach the phone screen cable and secure it. REMEMBER TO PLACE THE ELECTRICAL TAPE OVER THE CONNECTOR (I forgot to). Then remove the colored plastic, leaving behind the adhesive, and push the screen into place.
Of note: the seal peace at the top goes under the speaker screen, and the seal looks at first like it is reversed. To install that one accurately adhere it to the Screen itself not the body of the phone. align it where there is a see through circle along the seam and a hole in the adhesive. the sealant should run below the speaker screen. When readhering the screen to the body, remove the plastic guides around the body, then last the seal on the screen and align and install.
Super, c'est vraiment à la portée de tout le monde, il faut juste un peu de patience et d'audace.
Je viens de réussir le remplacement de mon écran et c'est impec !
Il n'y a que sur la première partie, où il faut insérer le médiateur, que ça a été compliqué pour moi. Impossible de l'insérer du côté des boutons (à droite donc), par contre quand je me suis décidée à tester en passant par l'autre côté, c'est venu tout seul.
Aussi il m'a fallu un certain temps pour comprendre que sur les adhésifs, seul le trait noir colle, et c'est donc à lui qu'il faut faire attention.
Pensez à vérifier que l'écran est fonctionnel avant de le recoller, à mon premier essai la nappe n'était pas bien insérée et j'ai du recommencer l'insertion. Voila, prendre son temps et vérifier que tout va bien à chaque étape et c'est très facile. J'ai mis un peu moins d'une heure.
After I clipped the screen in place, I realized that I had forgotten to reattach the screen bracket from step 14. Do you think this is dangerous? Can anyone assess this? In any case, the smartphone turns on and actually makes a good impression.
Many thanks in advance for your assessment!
Kind regards
Tom
Just some advice before you install the screen regarding the earphone grille/mesh at the top.
Something I experienced, was that the speaker grille did not end up being seated quite right when the phone display was stuck down. It is slightly bent, and the top edge is stuck out at a slight angle - it is quite sharp and does not take much to catch a finger on it, when the phone is out of a protective case.
I think this was because I laid the screen in, starting from the top and with it up at quite a steep angle, then working from top to bottom. I would suggest that when setting the new display within the device, that you align the bottom edge first instead.
I am not going to risk lifting the new display to try and re-seat this grille properly, the display cost me a bloody fortune (around 58% of the phone's original price) and I am not risking breaking it over something as minor as that.
nb. I definitely removed all the coloured plastic protective pieces before installing the new screen into the phone.

Where do you recommend that I purchase the Pixel4a screen replacement from? I found these two with Witrigs being cheaper, but not sure if either are reliable high quality screens.
@samomio Where do we install the double-sided tape for the replacement? Any areas we should not cover? I tried UV glue, but it is not holding the display securely.
Install the double-sided tape in the space between the outside edge of the glass and the OLED screen, all the way around.
Question- why does every phone repair shop automatically replace both the glass layer and the lcd layer even if the glass is the only thing that is broken?
Good question—because OLED screens are destroyed by the oxygen in the air once their screens are cracked or separated.
Hey, nice guide!! Do you know if the Pixel 4a and 4a 5G are interchangeable between them? Thanks!!
Thank you! The 4a and 4a 5G screens are not interchangeable. The 5G is larger.
Excellent guide.
I bought this screen from eBay: https://www.ebay.de/itm/402564264411
Already had tools in an iFixit kit.
Also bought some 1mm Tesa Tape from iFixit to glue the screen back on.
Got a replacement screen off Amazon, had a major scare tho, I tested it before going deep into the repair process, worked fine, removed all the adhesive, reattached the replacement screen it it was all black. Like dead. Phone was still vibrating, I made sure nothing was covering the proximity sensors or anything, still dead screen. I take a break, come back, dis-attach and reattach and the screen several times and its working again. Weird, but now very scared I delicately put it all back together. Make sure you transfer over the speaker grill on top, it doesn’t come with most replacement screens.
Hey guys & Ifixit team… what kit it s better to use for smartphones as a beginner : Essential Electronic or iOpener or Smartphone Repair Kit ?
The big pbl is finding the display…anybody bought form alibaba / alliexpres? Thanks a lot!
Water damage all over the screen from about 2 TBs drop of water on it. Picked up the phone and wiped it thinking its nothing . MAN God know I was wrong. The screen literally SIP water from the sides. 3 Days later and the screen is done. WARNING : If ANY water is left for a couple seconds PRAY. Now ALL of the screen is now purple from water stuck inside it. NEVER AGAIN GOOGLE.
CAN SOMEONE TELL ME IF IT IS IMPORTANT TO BUY THE CORRECT SCREEN VERSION NUMBER? AS PIXEL 4A 4G G025 /G025N /GA02099.
Because sellers don't specify it, is it really relevant? They just sell as Pixel 4A 4G compatible.
Thanks overall!
where do I buy the actual google pixel 4a screen itself? On Amazon? On eBay? Pls answer me
Replacement screens are now available from iFixit here.
Andrew S -
Where do I buy the google pixel 4a screen itself? Which website? And is it cheaper to buy the toolkit bundle or Buy the speelste tools one by one
Phone will not power up after dropping in bowl of water. Can anything be done to recover.

Be aware that removing a shattered screen will be tedious and you must be patient and careful to remove all of the bits from the glue channel between the screen and the phone body. Removing the old glue is a VERY tedious and time consuming process so be prepared to take considerably longer than the 30-60 minutes shown in the directions. Also be aware that having a magnifiying headset with lights should be a high priority purchase along with this kit. Re-attaching the screen-to-phone connector is also incredibly tedious and frustrating. It took more than 8 hours of work to get ours replaced. At first it all worked fine and 10 minutes later the screen failed. Be prepared to either be delighted that your efforts bring a phone back to life or that it will end in utter failure and frustration... it is NOT as easy as you think. The YouTube videos are all missing this information and make it all look easy...... not so.
If you get the kit that includes the adhesive strips, save yourself the risk and irritation and just get some B-7000 or whatever you see someone using in a YouTube tutorial. They seem to work, but it doesn't seem like they're actually cut for specifically this phone, or in my case none of the shapes really came close to aligning with any cutouts or holes. They only give you exactly what you need, so if you accidentally fail to line it up exactly right, you're stuck trying to maneuver this string of very sticky goop into a precise line or corner.
Otherwise, the tools are exactly what you need in a food way, very little waste and decent packaging. Great value overall, the screen is legit, although now my proximity sensor isn't working for some reason. They're pretty good quality, I'll keep it all around, but will be ordering some better adhesive and maybe redoing it. It really is not fun working with those, and I'd appreciate more for my money in that respect.
Also the picks aren't thin enough, risky using them.
I have problems with my proximity sensor, too. I'll open the phone again to see if it gets fixed.
That was really useful. Thanks for the info and clear steps. I did end up having to push the middle of the connector when reattaching the screen.
When the kit is going to be available?
After advice please - have been using my 4a with cracked screen for a while, but after dropping it last week the screen had a green intermittent flash across it, and nothing else. Pressing the power button to switch off seemed to have no effect. Can anyone please advise whether they think a new screen will resurrect it, or does it sound as though I have broken something else too? Thanks!
After having followed this guide and successfully replaced my screen, I have to say that it stops rather abruptly. It is very detailed, but then it says "apply the strips by following a generic give and put it together again" which is the most tedious part and should be documented. There should be a guide for where which adhesive part belongs, as some have differences just in millimeter scale. Eventually, I noticed that the product page for the adhesive has a picture showing the pieces aligned correctly. Contrary to what is shown in the linked generic adhesive guide, those are supposed to be applied to the device housing, not the screen.
Also, you should NOT apply the top adhesive, as one comes pre-applied to the screen.
There was also an Earpiece Speaker Mesh pre-applied to my new screen, in addition to the one that comes extra, so don't apply the other one on top! In my case, the Mesh was pre-applied inside-out, which I realized just a second before pressing the screen onto the adhesive for good.
1/2
2/2
When it comes to making sure the mesh is aligned correctly, special attention is required. The slightly shorter side of the mesh is supposed to be the bottom side, which means the picture on the product page currently shows it upside-down.
Those are my main gripes with this guide and I think their omission sets newbies up for failure and frustration, which I would assume is the opposite of what ifixit wants when promoting self-repare and should not exist for an “official” self-repare done together with google.
Small additions:
Step 14 tells you to re-attach the connector by clicking in one side first, then the other. I am pretty sure that it means to say and should be pressing down coming from the top edge, then the bottom (or the other way around), but not the sides as in left and right, which is exactly what would make it misaligned.
Also, I would emphasize that if the plastic is not smooth after the removed old adhesive, it is almost certainly hard dried glue. Scrub with the cleaning alcohol pad here.
Après avoir cassé mon écran, et face aux coûts annoncés par les réparateurs professionnels, je me suis lancé dans la réparation seule. De façon assez surprenante, c'était relativement facile excepté l'installation de l'adhésif qui demande beaucoup de minutie. Je conseille l'achat d'un pack d'adhésif supplémentaire pour être plus serein.
Pour l'instant tout a l'air de très bien marcher, je recommande grandement.
Coll down guys and gals.
1) go below the Display and not between the backcover/middle (see the other comments)
2) just take care about the flex/display cable position (which is iirc about on the middle i.e. 2nd 3rd from the bottom ON THE LEFT side dear OP)
Everything else is just separting the glued on Display from the Phone.

I've measured it: The cable starts arround 1.4-1.6 cm from the lower half from the bottom on the left side.
So You can cut the bottom left corner and of course the upper left one but for safety's sake, watch out for the camera.
You can go up to 5cm down from the upper left side till You're near the cable.

When you say left side, is this your left when the phone screen is facing you?
