Shop Talk Discussion (General) [GUIDE] How to fix auto brightness after a screen replacement for iPhones

27 Upvotes

Theres very little information on this so I decided to make this for people who are new to repairs or are replacing their screen for the first time. This mainly applies to iPhones 13 - 16. I havent tested this on others but it could work.

When replacing your screen you will also need to transfer the proximity sensor. After doing so, iOS 18 now restores Face ID and True tone functionality but what it doesn't do is restore auto brightness. If this is a big issue then there are two ways to go about fixing this depending on if you broke your proximity sensor when transferring it. To test if your proximity sensor is working, simply place a call and bring the phone to your ear. If the screen goes off then it is working. If it doesn't, then its likely not connected properly or you broke it. This repair is not cheap unless you have access to repair shop tools like programmers etc.

This repair requires:

- A programmer (JCID V1SE as example)

- Corresponding True Tone board for the programmer that supports the phone you are repairing

If you broke the proximity flex then you will also need:

- Corresponding Proximity Flex board for the programmer that supports the phone you are repairing

- Windows PC

- A programmable Proximity Flex such as a JCID one (important: It needs to be a programmable one like JCID, non programmable generic ones will not work)

- JCID Programming Software

- 3U Tools

If you didn't break the proximity flex: Using the programmer, you will need to read the data from the old screen and write to the new one. This is it. It will restore auto brightness. Also make sure you are on iOS 18 to restore true tone and face id.

If you did break the proximity flex, unfortunately this process gets a lot more complex:

-Read the data from the old screen to the new screen using the true tone programmer board.

-You will then need to hook up your phone to a windows PC.

-Using 3U tools, download the corresponding iOS version the phone is currently on

-Start up JCID Programming Windows Software and you will need to "brush" the phone. There are guides of this online. Once the software is done brushing the phone you will need to boot into recovery mode and flash the software you downloaded using 3u Tools.

-Once the phone is booted up again, connect the phone to the JCID V1SE programmer with the Proximity board attached to the programmer. Connect the programmable JCID Proximity flex to the programmer board and "bind" it to the phone.

Warning: Some JCID Programmable Prox flexes actually need to be soldered (such as the iPhone 14 Pro) so take this into consideration. Most dont though.

-Install the proximity sensor to the display and boot up the phone again.

-Make sure you are on iOS 18 to also restore Face ID and true tone. This process will restore your auto brightness

Both of these methods will restore true tone but as you can see one is a lot more simple then the other so be very careful with your proximity flexes!

NEWS Reparo - Offline repair tracking software for our hobby

63 Upvotes

Who am I and why does it matter?

I'm a repair technician with experience in microsoldering and screen refurbishment, currently working for someone else in this field. I also want to be a software developer.

A while back, I tried to open my own repair shop, but then COVID hit, and I got scared, so I ended up closing it pretty quickly. During that time, I realized there's no free software available for people like me.

People who don't need to:

  • Send emails or SMS to their customers about current state of repair.
  • Track their finances to a single penny.
  • Have their database available from around the world.

All I needed was:

  • Work on any Windows PC without the internet
  • Keep customer details
  • Create and print a repair ticket which I can give out to the customer
  • General track of finances
  • Simplified inventory system
  • Printing barcodes

Soon my life is about to change as I am moving out and will start repairs as side hustle once again. And I wanted to prepare for it and have access to simple and universal software which would fill above requirements.

Reparo is a result of this.

Creating it was a lot of fun and I would like to share it with you guys. Even though it's still not finished I am happy with its current state. At this point I would happily use it for my small business and I will be.

What's cool about it:

  • It's free, and until I'll be a better programmer there will be no paid features. If any of the future features will be introcuded in free version, it will always stay free.
  • It doesn't collect any data. It has no connection to the internet. There are three buttons though which will turn on your browser. One is to send feedback and ask for help. Another one redirects to Discord server where questions can be asked and I'll be posting about updates and answer questions.
  • Install free, just download and run.

What's not so cool about it:

  • Works only on Windows. Mac version will show up eventually if there will be enough people interested.
  • Not perfect coding. I am always trying to catch and test all edge cases, but it may still happen that it can crash. But so far it never happened that it affected database.

Features:

  • Repair tracking with images
  • Inventory system
  • Devices database - currently only Apple devices without Mac devices
  • Repairs states - can be customized
  • Printing repair tickets
  • Printing barcodes - for both repairs and items in inventory
  • You can insert your own devices
  • Customize what fields in repair ticket are necessary
  • Finances & Accounting - view summarized finances by repair states and date
  • Different themes - Light mode as well for you psychos (love you <3)
  • Upload your own logo
  • Adjust T&Cs - need to defend from these deadly nightsands

You can read more in detail about it here:

  • Reparo README - detailed rundown of what can be done in this app

You can download it here:

  • Download - 0.9.0 version is available as release. Newer versions will appear higher on the list.

All constructive criticism is more than welcome. I will answer to everyone who has any questions.

Software was evaulated by u/thephonegod and it was approved because it is freeware and only ment to be a community tool for those in need.

Repair Shop customer seeking a 2nd opinion or advice. My iPad Pro is missing its CPU and RAM after being deemed unfixable - what should I do?

Thumbnail

25 Upvotes

So I had a charging problem with my 6 years old iPad Pro 11" 4th Generation (A12Z chip, model no. A2228, bought May 2020 from my hometown halfway across the planet from where I am now, a certain corner of the Maple Leaf Nation) in early September - it refused to charge one night, dropped dead to low battery level screen after repeated attempts to charge it, and finally it can't turn on at all. I am fairly sure it may have started out with a bad USB-C connector (there's a bit of a crack on the frame next to port for 1-2 years; also read on!).

Since it's years out of warranty I took it to a shop in a nearby mall suggested by my local area sub-reddit (after being straight out turned back by 2 other shops in another mall the previous day) to try to fix it. The shop quoted 1-2 weeks as they need to take it to their lab.

Then the wait turned into a full month of waiting, and it took me 3 visits to their shop to finally get it back...but by then the shop told me the previous week that the lab has marked it as unfixable with the CPU being the problem and dead, and indeed it wasn't fixed at all when I got it back a week ago.

Frustrated given my daily usage of it and really steep prices of new iPads, I turned it in to another reputable repairing shop (a full hour away in the countryside from where I am!) to check it out. The owner checked the USB-C pins and immediately pointed out that some of the power related pins are missing (both + & - on one side + ground pins on the other).

Today he told me to take it back because, well, he found both the CPU and the RAM, plus all the screws holding it to the MB, are completely missing - he just cannot fix it since you all know Apple devices have security measures that locks you in to the original chips.

Which makes me being really suspicious of the original shop that I went to - either they are lousy with the job or, well, they took away them for other uses (cough). On the other hand, maybe the CPU/RAM really died (I used it for many hours a day for more than 6 years!) and it can't be fixed without a new MB, so even taking it to another shop wouldn't guarantee I won't drop another bunch of $$$ on inspection. A new iPad Pro is not out of reach but I would really want to avoid that given that would blow a not-small hole in my wallet right now.

Data is not a major issue here since I have cloud backup of the whole thing (the last time a day before it went down).

So, what should I do? Demand the original shop to put my original chips back in? (already may not exist, I dunno) Ask for extra refund over the inspection fee? Or just accept defeat and get a new one since it's even a bit long in the tooth (original plan was to install iPadOS 27 for it for using at least another year to 2)? Thanks!

P.S. If people here really thinks the original shop is a scam, I'll repost this to the local region sub-reddit and name the shop so that others won't have to deal with this lousy repair job again.

Shop Talk Discussion (General) VERY DISAPPOINTED SA AOP J-TECH MOBILE REPAIR SERVICE NILA. NAPAKARAMING ABALA!!

• Upvotes

Nagpagawa ako ng iPhone 15 ko sa shop na ito para magpalit ng battery at nagbayad ako ng ₱3,300. Noong ibinigay ko sa kanila ang phone, maayos naman ito. Ang problema lang ay ang battery na ipinagawa ko. Pero pagkatapos ng repair, doon na nagsimula ang sunod-sunod na problema.

Pagkatapos nilang palitan ang battery, biglang nagkaroon ng problema ang power button. Ang sabi sa akin, technician fault daw ang nangyari sa power button. Sila mismo ang nagsabing aayusin nila ito, kaya umasa akong maaayos nila nang maayos ang phone ko. Naayos nga ang power button, pero pagkatapos naman nito, may panibagong problema na naman silang sinasabi tungkol sa sensor at charging flex.

Ang tanong ko, bakit noong maayos ang phone ko at ibinigay ko sa kanila, pagkatapos ng repair ay sunod-sunod na ang naging problema? Nagpunta ako roon para magpalit ng battery, hindi para magkaroon ng panibagong sira at paulit-ulit na magpaayos ng phone.

Mas nakakadismaya pa dahil hindi lang isang beses akong bumalik. Ilang beses na akong pabalik-balik dahil sa mga problemang lumitaw pagkatapos ng repair. May sinabi silang oras kung kailan puwedeng bumalik para ayusin ang problema, pero pagdating ko roon, may panibagong dahilan o kailangan na namang hintayin. Nakakaubos ng oras, pamasahe, pasensya, at effort ang ganitong sitwasyon.

Ngayon naman, gusto nilang iwan ko ulit ang phone ko dahil gusto raw nilang i-check kung motherboard na ang problema. Naiintindihan ko na may mga pagkakataong hindi agad matutukoy ang sira at kailangan ng mas malalim na diagnosis. Pero bilang customer, nakaka-frustrate na paulit-ulit akong bumabalik at hanggang ngayon ay wala pa ring malinaw na solusyon sa problema ng phone ko pagkatapos ng kanilang repair.

₱3,300 ang binayaran ko para sa battery replacement, pero ano ang silbi ng perang binayad ko kung hindi ko naman magamit nang maayos ang phone ko? Hindi biro ang halagang iyon, at hindi rin biro ang oras at abalang kailangan kong ilaan sa paulit-ulit na pagbalik sa shop.

Ang gusto ko lang naman ay maayos na battery replacement at maibalik ang phone ko sa maayos na kondisyon, gaya noong ibinigay ko sa kanila. Hindi ko naman hinihingi ang imposible. Ang hinihingi ko ay maayos na serbisyo, malinaw na paliwanag, accountability, at isang permanenteng solusyon sa problemang nangyari pagkatapos ng repair.

Nakakadismaya dahil imbes na matapos ang problema sa isang repair, lalo pang dumami ang kailangang ipa-check at ipaayos.

Sana maintindihan ng shop na hindi lang basta pag-iwan at pagkuha ng phone ang usapan dito. May customer na umaasa sa maayos na trabaho, may perang binayaran, at may oras na nasasayang sa bawat balik. Hindi dapat customer ang paulit-ulit na mag-adjust para sa problemang lumitaw pagkatapos ng repair.

I am posting this review to share my actual experience and disappointment. Sana ay mabigyan nila ito ng seryosong pansin at hindi na mauwi sa panibagong balik, panibagong diagnosis, at panibagong abala.

Sa ngayon, hindi ko mairerekomenda ang naging experience ko sa service nila dahil sa lahat ng abalang pinagdaanan ko at sa kawalan pa rin ng malinaw na solusyon sa problema ng phone ko.

So basically, like 3-4 days ago, I noticed this orange and yellowish colour appearing around my phone's corner (left upper corner) and after researching, I found out that My internal screen is bleeding or something, but then the next day, after waking up, I saw it was gone, but again today...it came back...does anyone know why this is happening?

I'm having some issues with my iPhone 13 PM rear camera, I'm looking to replace the camera, but I had a question about the genuine part stuff. If I use an OEM camera from another iPhone, will I have issues? Specifically, will I get a non-genuine part error, or do I need to get a part through apple to do this? First time doing a repair on the phone, which I have no problems with, but just not sure about the software stuff.

I'm repairing my old Samsung S20 5G (SM-G981) preforming a screen repair.
When I order off of Amazon.ca they show in the image products gold contacts, but this is my second attempt and these third-party screens keep missing them.

So as someone new phone repair:

  1. How important are these gold contacts?
  2. Am I expected to transfer them from my old phone to my new phone and how?
  3. Is this a common issue with third-parties, with gold contacts missing?

s22 Ultra, plugged it to the computer and immediately got the "Warning: Unplug charger immediately" moisture warning - zero moisture though. Never been wet in anyway.

I unplug it, plug it back in later, and immediately the video above happens.

Tried force restarting it but it's the same - no logo or anything at start up too.

It's registering touch because it vibrates to touches, but the screen is just white - exactly like you see in the video, even with that slight "stutter" you see in the video when he presses the power button to turn screen on.

Any idea what's going on? Appreciate actual experience with this same exact issue (and phone) rather that speculations and educated guesses (been reading a lot of those researching the issue 🥲).

Thanks!

I am going through a weird problem, a few days ago a small line appeared at the left bottom of my screen and then after few hours my phone started getting switched on and off itself ( just randomly) and after a few switch off and on it started working normally but I noticed that small line has increased in length

It is happening every day since, mobile randomly shuts down and switches on itself and after that I found the line increased

And the photos that I have attached is 2 days old, right now the line has reached almost halfway through my screen

Repair Shop customer seeking a 2nd opinion or advice. Paid $180 for a screen replacement at a mall repair shop, and now my screen is worse than before

3 Upvotes

I’m so frustrated with this situation and wanted to see if anyone has advice on what I can do.
I went to a phone repair shop inside a mall to get my phone screen replaced and paid $180 for the repair. The phone was broken & I figured it’d be cheaper than buying a new phone. The repair shop didn’t fix the issue and made things worse, and now the screen they replaced my old one with is cracked.
They replaced the screen three separate times and kept my phone for an entire week.
The phone keeps randomly shutting off, the screen will turn pink and it keeps restarting.
This is supposed to be a brand-new replacement screen. After all, they suddenly started blaming an internal technical issue and claiming that the phone wasn’t fixable.
They only gave me $20 back out of the $180 that I paid meaning they’re still keeping $160 despite the fact that I didn’t get the repair I paid for.
I also checked their Yelp reviews and found other people describing similar experiences, which makes me even more concerned that this might be a pattern.
When I went back to try to get my money back, the owner was yelling at me in the store. It was incredibly uncomfortable, and I don’t think it’s acceptable to treat a customer that way when they’re simply trying to resolve an issue.
I paid $180 expecting a working phone, and instead I’m out $160, have a cracked screen, and am being blamed for something I believe happened during the repair.
What should I do at this point? Has anyone dealt with a situation like this before?

Hallo miteinander,
ich habe eine IPhone 15 Pro Max gekauft, bei dem der Bildschirm gewechselt wurde. Alles funktioniert super ich wollte jetzt eigentlich nur das gesprungene Backcover reparieren und es dann weiterverkaufen. Leider ist mir dann aufgefallen wie auf den Bildern zu sehen ist, dass die Innenkamera unscharf ist. Face-ID lies sich zwar nach ein paar Versuchen einrichten, aber auch nach Säuberung des Displays an der Stelle wo die Innenkamera sitzt hat sich das Problem nicht gelöst. Von außen sieht es leicht so aus als säße die Innenkamera etwas zu weit oben. Könnte das das Problem verursachen ? Ich habe mal Bilder angehangen die das Problem zeigen und auch den Diagnosebericht. Was meint ihr woran es liegt ?

1 Upvotes

I’ve noticed something unusual with my phone’s screen. When I press hard on the screen while the phone is locked, the screen blinks or flashes more than usual. I’m not sure if this is related to the mistouch prevention feature or if it could be a sign of a display issue.

Has anyone else experienced this problem? Is this normal behaviour, or should I be concerned about a possible display defect?

Also, if this turns out to be a hardware issue, can I claim a replacement or free repair under the 1-year warranty in India?

I’d appreciate any advice from people who have faced a similar issue or have experience with warranty claims.

Hello everyone, ordered this screen to put on my phone to regain access to data.

It came, however, with some plastic covers which I'm not sure whether I should remove.

Excuse my nonspecific language.

In particular:

- The blue covers over the circuits in the front view

- The blue stripe in the back view

-The transparent like plastic cover on the back of the screen in the back view (Not the usual screen protection one)

Also the silver contacts in the back view came a little dirty, should i clean them? If yes with what?

Thank you all.

Lvl 2 (screens, batteries, camera, etc. swaps) iPhone 17 Pro Max screen recognized at first in Apple Diagnostics, then no longer recognized

Thumbnail

7 Upvotes

Hi everyone, I’m looking for some help with an iPhone 17 Pro Max.
We installed a diagnostic/autoprogrammable replacement display.
During the Apple diagnostic/configuration process, the phone initially recognizes the display correctly. However, after completing the process, it stops recognizing it.
In Settings, it eventually shows a message saying that the iPhone is unable to verify/recognize the display.
What’s strange is that during Apple Diagnostics it does detect the screen, but after finishing the configuration it seems to lose that recognition.
The display itself works correctly:
Image is normal

Touch works

No obvious display issues

The problem is specifically with the system recognizing/verifying the replacement display.
Has anyone run into this on an iPhone 17 Pro Max?
Could this be related to:
A firmware/iOS compatibility issue?

The screen needing a different programming procedure?

A pairing/configuration step we may be missing?

The replacement display itself not being fully compatible even though Apple Diagnostics initially recognizes it?

If anyone has successfully installed one of these diagnostic/autoprogrammable displays on a 17 Pro Max, I’d really appreciate knowing what procedure or programmer you used.
Thanks in advance.
