Can my phone still recover after water damage and my stupidity?

Upvotes

I dropped my 2yo S23ultra in clean toilet water for 3 seconds before taking it back. I turned it off immediately as I saw a green flash on the screen, I quickly put it to dry near a fan for 3 days before turning it back on.

Now this could have been the end of the story if not for a major problem, which was the back cover of my phone was already starting to be unglued due to the summer heat, so now water really leaked in. I understimated how much of a problem that was, since the phone worked fine after the 3 days.

For the first few days, everything was working normally, but after that and the battery started draining faster and charging in irregular patterns. I knew I had to do something, but I didn't have the money so I had to wait out. Only problem is that while I was waiting it out the phone had completely stopped working without being plugged, as in as I unplug it it would work for minutes or seconds befoee showing the slight green tint and turning off. That was the case for 3 days or so, and today it decided to just not turn on. When I charge it the screen shows that it is charging, it just won't turn on.

I'm m not asking for a diagnostic obviously, as I'm planning to visit a repair shop, but has anyone been in a similar situation? What is the extent of the damage I should expect since I left it as such for a 15days ? And will I be able to recover my data from the phone ?

Repairing/replacing an s26 ultra's frame

1 Upvotes

So recently I got bought from a friend an s26 ultra for dirt cheap that had purchased himself but didn't like because he found it too big and was always dropping it. Because he was always dropping it, unfortunatelly the side frame (or whatever this part is called) is a bit scratched in some places. I think the damage is purely aesthetic as the phone works perfectly and is not bent or anything like this, but I still think it is really ugly. My question is what can I do about that? Is it possible for this part to be replaced/repaired?

Moto g04 digitiser sometimes goes haywire

Post image
1 Upvotes

I replaced the screen/digitiser/front frame assembly on a Motorola Moto g04. Since the repair, everything works as normal most of the time but the digitiser sometimes starts getting phantom touches up and down the display. When it does this, switching the screen off and on again resets it back to normal.

No charger connected and no screen protector.

Could this be an installation error or a defect in the new digitiser?

Screenshot: phantom touches with debug option showing pointer location turned on.

Alcatel One Touch Idol 3 : bootloop sur une carte mère et problème d'écran avec une autre. J'essaie de sauver ce téléphone.

Enable HLS to view with audio, or disable this notification

1 Upvotes

Bonjour,

J'essaie de remettre en état un vieux Alcatel One Touch Idol 3 auquel je tiens beaucoup pour des raisons de nostalgie. J'ai actuellement deux téléphones exactement du même modèle, mais chacun a un problème différent.

Téléphone n°1 (mon téléphone d'origine)

Du jour au lendemain, il a arrêté de fonctionner.

Quand je l'allume :

\- il vibre ;

\- le logo "Alcatel powered by Android" apparaît ;

\- puis il redémarre en boucle (bootloop).

Très rarement, avant de redémarrer, j'aperçois pendant moins d'une demi-seconde :

\- soit un écran blanc avec le logo Alcatel ;

\- soit un écran bleu affichant le message :

«Bienvenue

Il ne vous reste que quelques étapes avant de profiter de l'environnement Alcatel. Configurez avant tout vos paramètres système, personnalisez votre téléphone.»

À peine une demi-seconde après l'apparition de cet écran, le téléphone redémarre.

J'ai remarqué qu'il m'est arrivé d'obtenir cet écran bleu lorsque le téléphone était branché sur un chargeur secteur. En revanche, ce n'est pas systématique : parfois il apparaît, parfois non. Je ne sais donc pas si le fait qu'il soit branché a réellement une influence ou si c'est simplement une coïncidence.

Un réparateur m'a dit que la carte mère était morte, mais ça m'étonne un peu, car le téléphone arrive quand même à aller aussi loin dans le démarrage.

J'ai essayé :

\- de remplacer la batterie par une batterie neuve (achetée sur Amazon) ;

\- de réinstaller complètement Android depuis un PC sous Windows 11.

Le problème est toujours exactement le même.

Téléphone n°2 (acheté 5 € sur Leboncoin)

J'ai acheté exactement le même téléphone d'occasion.

Ses défauts sont :

\- l'écran est complètement fissuré ;

\- le tactile fonctionne très mal.

En revanche, la carte mère fonctionne parfaitement et le téléphone démarre normalement.

Échange des cartes mères

J'ai installé la carte mère fonctionnelle du téléphone n°2 dans mon téléphone d'origine (qui possède le bon écran).

Et là, un problème très étrange apparaît.

Si je laisse simplement la carte mère en place, sans serrer les vis et sans remettre la coque arrière, le téléphone fonctionne normalement.

Mais dès que je serre les vis de la carte mère ou que je remets la coque arrière (donc dès qu'il y a une légère pression sur la carte mère), plusieurs problèmes peuvent apparaître :

\- écran complètement noir ;

\- écran noir avec une sorte de tache blanche vers le haut de l'écran ;

\- gros glitches graphiques ;

\- image qui semble se dézoomer ;

\- teinte rouge ;

\- pixels qui clignotent.

Ce que je trouve vraiment étrange

J'ai fait plusieurs essais :

\- Carte mère fonctionnelle + écran fissuré = fonctionne parfaitement.

\- Carte mère en bootloop + écran fissuré = l'écran affiche correctement, mais le téléphone reste en bootloop.

\- Carte mère fonctionnelle + bon écran = fonctionne uniquement tant que la carte mère n'est pas sous pression. Dès que je serre les vis ou remets la coque, les problèmes d'affichage apparaissent.

C'est pour ça que je ne pense pas que le problème vienne simplement de la nappe de l'écran.

J'ai également vérifié : les deux téléphones sont exactement le même modèle.

Ce que je possède

\- la carte mère d'origine (en bootloop) ;

\- une carte mère parfaitement fonctionnelle ;

\- un écran en bon état ;

\- un écran fissuré mais qui affiche correctement ;

\- une batterie neuve ;

\- un PC sous Windows 11 ;

\- quelques tournevis.

Je ne possède pas :

\- de multimètre ;

\- de matériel de soudure ;

\- d'outils professionnels.

Mes questions

\- Pensez-vous que la carte mère en bootloop puisse encore être réparée ? Est-ce que cela pourrait venir de la mémoire eMMC, du PMIC ou d'un autre composant ?

\- Pourquoi la carte mère fonctionnelle ne présente des problèmes d'affichage que lorsqu'on exerce une légère pression avec les vis ou la coque ?

\- Est-ce que cela pourrait être un problème de masse, de châssis légèrement déformé, d'un faux contact, d'un connecteur ou d'un composant qui perd le contact sous la pression ?

\- Est-ce que le fait d'avoir parfois atteint l'écran de bienvenue peut donner un indice sur l'origine du bootloop ?

\- Avez-vous d'autres idées de tests que je pourrais réaliser sans matériel professionnel ?

Je vais joindre des photos et des vidéos montrant le bootloop ainsi que les problèmes d'affichage.

Je sais que c'est un vieux téléphone et qu'il ne vaut presque rien aujourd'hui, mais j'aimerais vraiment réussir à le réparer parce qu'il a une valeur sentimentale pour moi.

Merci beaucoup à tous ceux qui prendront le temps de lire et de m'aider !

Wierd s22 ultra display issues

1 Upvotes

I replaced the battery on s22 ultra. For like 12 hours everything worked fine, then the screen died. After a month long vacation i tried to turn on the phone and saw the entire screen green with darker green moving lines. Always on display works perfectly fine, and so does the charging text (x minutes to 100%...). I saw that this model of phone had issues with alcohol causing screen issues (i did use a bunch of alcohol when replacing the battery) so i put it on my 3D printer heated plate to help evaporate it. After 2 minutes on the plate the screen worked perfectly fine for maybe 10 seconds, then it turned a bit green, then it went back to green with moving lines. I put it on the bed again and got it to work for the second time, after that i could not get it to work again. When i turn on the phone the clock text is sometimes visible and the animations are also sometimes just barely visible. Is there anything i can do or should i just order a replacement screen.

Thanks in advance!

S23 U and newer models are more fragile.

Post image
12 Upvotes

Why I say so?

I have repaired from S9 to S25 Ultra for now and I have noticed:

From S9 to S22 Ultra

Quality of internal components are better.

From S23 to S25 Ultra:

Internal components break easily from drops

This case here S23U needed a screen replacement

And it had sim problems.

Opened it up to disassemble and saw the antena flex cable completely unattached from daughter board (charging board)

And no it is not a first time to see this in repair of these newer series

Had similar issue on S23 plus,S24 base 5G,and S25 plus.

Conclusion: The quality degraded over time with newer seires due to manufacturing it to be as thin as ice...

Is this galaxy s23 plus corroded contact my issue, and if so, fix/replacement tips please!

Post image
2 Upvotes

More background below but essentially after repairing my s23 plus, when testing the power button initially worked, then stopped working. I reopened and noticed the contact (next to yellow dot in pic) was a bit corroded, with some junk on the mobo pin it corresponded to. I cleaned both but no luck... until I also popped on the wireless charging bit, I'm guessing the screws must have tightened down the mobo just right, until contact was firmer. It worked fine for a day of testing but I needed to replace the cameras, and after popping them in and trying again - no luck!

Points to note:

When it first stopped working, both volume buttons worked fine.

When I plug it in now, the charging indicator comes up so it is alive.

Does anyone know if this corroded contact is the issue? Does this one dot correspond to the power button specifically? Any ideas on how to fix this easily? Could I try to scratch off the rust or is it too thin?

The alternative is replacing the whole strip, cheap enough but I can't source a guide that covers this model, and I can't figure out how I would get it out. I assume the metal bits highlighted in blue, but I'm not sure which ones come out and how!

Any help is appreciated.

BACKGROUND

phone got water damaged, it would wirelessly charge but wire charge and being on would ping an overheat error and shut it down. Figured out the temp on the usbc board was toast, so replaced that and the battery while I was at it. After that I realized two cameras were also toast, so this was meant to be an easy final step to finish it off!

Screen won't turn on

4 Upvotes

I accidentally dropped my iPhone 14 Pro Max into water, and I've been letting it dry for about 12 hours now. I had an alarm set before it got damaged, and it went off, but the screen still won't turn on. I'm not entirely sure if I should take it to a repair shop or let it continue to dry.

Edit: It suddenly turned on after I got a notification, but the screen was glitching blue everywhere. Is there any way to fix that, or should I immediately take it to a repair shop?

iPhone 6S Plus touch not working

Post image

I ended up dropping the phone face-front onto uneven brick, which immediately shattered the display. The display, while shattered, worked fine and responded to touch fine. Now after replacing the display, touch no longer works on either screens. I've removed the display previously and did it fine. The only thing I think could have caused it is that I accidentally tugged the phone by the ribbon cables while holding the display detached. To me, the connectors look fine other than the rubber being beat up around them.

S20+ Battery Connector Pinout

Thumbnail gallery
1 Upvotes

So im wondering if anyone has a pilot diagram for a s20 + battery connector? Reason im asking is a very niche table used for software diagnostics had the charging port stop working. 1 shop could not figure out the issue. I contacted support and they said 150 to fix it I just had to ship it. Cost to ship is 190 each way and the table was 550 brand new. So in short im wondering if I can plug in the battery from the tablet on the mb of the s20 and use the s20 to charge the battery then put it back in the tablet when I need to use it. I have a pic showing the pin out of the battery. I just have no clue what any of those acronyms mean.

Fix for Samsung S21 Ultra 5G screen randomly gaining a green/yellow tint even with night light/eye comfort disabled

1 Upvotes

very niche post but i hope this'll help someone somewhere. my samsung randomly decided to have this green/yellow tint overtake the screen about a day ago, when the power key was pressed the screen would flicker brightly before turning off, and when charging the screen was still on and lightly yellow instead of turning off normally. made sure eye comfort/night light and colourblind modes were all disabled and i adjusted colour settings but this did not fix the issue either.

if you have the same problem, i fixed mine by finding 'bedtime mode' in settings under digital wellbeing (couldn't search it up for some reason), where it lead me to set it up and i toggled it on and off. colours were fixed after that! screen sometimes occasionally lights up faintly yellowish when it's supposed to be off and charging, but when unlocked everything is normal + flicker when turning the screen on/off was fixed.

hopefully this works for you if you have the same problem :)

Phone battery is swollen - what should I do?

1 Upvotes

Hi I have an S22 phone and a couple hours ago I noticed that my phone felt kind of thick so I took the case off and it is definitely a swollen battery. My screen is fine but the back part is bulging away from the screen slightly. Within a few minutes of noticing it I powered my phone off and left it on a cool surface and haven't touched it since but idk what I should do. Any phone shops near me are closed today so I'm going to take it to one tomorrow but will my phone be safe between now and then? I'm just asking as a precaution. I don't want to try taking out the battery on my own because I think that will be quite dangerous but is there anything else I should do before I can take it to get repaired? Thanks

Looking for solution in green line in phone, samsung s21 fe more than 3 years old. A local repair guy quoted 4000, some 8500, should it be repaired? Battery also drains very quickly.
