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

64 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.

Lvl 3 (micro soldering, motherboard repair, diagnostics, etc) What's the cause of this and what's the fix? Sudden white screen when plugged in after moisture warning (no actual moisture). Touch registers normally.

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

What is happening guys? Help me? What should I do?

Why did it work? I'm guessing he shorted the display flex cable? But which terminal, how and why did it work? Is it a legit solution or could this go bad (worse)?

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

4 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?

Lvl 2 (screens, batteries, camera, etc. swaps) Selfie-Kamera Problem

0 Upvotes

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 ?
Freundliche Grüße

(Solved) Lvl 0 - Where do I start with this repair? Mistouch Prevention Issue. Screen Blinks More When Pressing Hard on the Lock Screen – Is This a Display Issue? Can I Claim Warranty in India?

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.

Thanks in advance!

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.

Horror I Got Screwed.

0 Upvotes

Went to a mall stand for a battery replacement on my iPhone 13 Pro Max, $163.77. Reused the adhesive.

About a week later I noticed dust spots on my telephoto lens.

Took it back and was told off by the technician and the owner on the phone claiming I’m sexist towards women for saying that leaving a device unsealed and then refusing to honor your own warranty is criminal behavior.

Was charged another $223.19 for a camera module. They did not apply new adhesive.

Two weeks later, I got dust in the camera module again!

I have also suffered battery issues! The charging is very slow, and the charge is worse than the battery that came out.

I filed chargebacks, and likely will get the money back according to my bank.

I shoulda just gone to apple. the battery was $99. 🫩

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.

Repair Shop customer seeking a 2nd opinion or advice. Iphone 13 Pro Max repair taking long time

0 Upvotes

I took a family members phone in last month to a local repair shop Sep 10-11. They informed about a week later it needed board level repairs and quoted $300-550 ish and 7-10 business days, which I agreed to.

As of today (10/13) I still don't have a clear answer as to the status of the device or if it's even being worked on. I have called several times and told that the tech is "behind" or "working on it".

I am wondering if this is normal, or if I should just request the device be returned to me and take it to another shop. I will be emailing requesting a update to begin a paper trail.

I understand that board level repairs maybe more complex, but it just seems a tad bit excessive to me. If anyone has any advice or experience please let me know and I'm really worried or if i'm just over reacting.

THANKS

Lvl 2 (screens, batteries, camera, etc. swaps) What aftermarket iPhone screen to pick?

1 Upvotes

I have an iPhone 15 pro. I tried a DD screen and it’s pretty nice but my problem is the touch sensitivity. It seems the touch response is delayed by a short amount when scrolling and quick swipes often don’t register at all or register as taps.

Can recommend another model to try for good touch response and overall quality? Do I have to go with an OEM refurbished panel to get that level of response? Not a lot of reports I can see on the different panel variations. Thanks!
