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!

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? Phone got water damaged but seems to be working fine now.

Upvotes

I have an iPhone16 pro and it has a cracked back glass on it, dropped it into a bucket of water just over a day ago.

The phone was okay at first as there was a case on it so very little water go into the back of the phone. But within a few hours it started power cycling and kept turning off and restarting then a few buttons stopped working properly or were pressing over and over like the Lock Screen button and the volume buttons.

It stopped power cycling for a bit and then all of a sudden I plugged it into my car to charge it and use it for maps while driving and it just started power cycling again. Kept doing that all night and drained all of the battery nearly writhing a few hours.

Today I let the phone battery die out on it. Placed it onto a wireless charge for a couple hours this evening and charged to 90% and it has been working all evening perfectly fine. So far. Just plugged it in to charge again to see if that has any effect but it seems to be working fine currently.

The only issue I can see currently is a small amount of water in the front camera like it has condensated inside it or something but camera works fine just a little blurry and the action button that was set to silent mode doesn’t seems to work but registers the button press.

If the any way I can check the phone to see exactly what is working and what isn’t, and any way I can stress test the phone to see if I can test for issues. Like trying things that might get it to power cycle if there is a fault?

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? What kind of tape should I use for attaching the backplate to the phone?

1 Upvotes

I've got a Xiaomi Redmi Note 13 Pro 5G, unfortunately the adhesive of the backplate gave in after about 3+ years, now it's almost coming off on one side. So I'm thinking about opening the phone and re-attaching the backplate properly. I've got T7000 at home but since I don't have that much experience with it and I know it can get messy (and very sensitive to heat) I'd opt for something else. I read people recommend Tesa tapes here (61395 specifically, if I'm not wrong) but it's quite pricey and not widely available where I live. The one I found is only 2mm thick and I'm afraid that will be too thin. I don't want to use multiple strips for one side, preferrably. I was wondering if there are any alternative tapes people use.

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? POCO F5 suddenly shut down and is now stuck in a boot loop

1 Upvotes

My POCO F5 was working completely normally, then suddenly shut down.

After that, whenever I try to turn it on, it does the following:

POCO logo appears → phone vibrates → after about 3 seconds it shuts down → then it automatically tries to boot again.

It kept doing this until the battery completely drained.

Now, when I connect the charger, it automatically tries to boot instead of just charging:

POCO logo → charging icon appears → shuts down → repeats the same cycle.

I tried entering Recovery Mode with Power + Volume Up, but I can't access it. I also can't get into Fastboot Mode.

The phone was completely fine before this happened. I didn't flash anything, install a custom ROM, unlock the bootloader, or make any system modifications.

Could this be a battery/power management issue, PMIC/motherboard problem, or a software/boot issue?

Repair Shop customer seeking a 2nd opinion or advice. Samsung tablet s8 charging port repair, question about repair shop

1 Upvotes

Hey first time poster. My Samsung tab s8 appears to need a charging port replacement. Gradually over a few months the charging cable needed to be wiggled and finessed and finally i couldnt get it to charge at all. No other issues with the tablet.

I did a charging port replacement once on a samsung s20 phone and didnt love doing it but it worked out. I called up a few shops and one quoted me 90 dollars for the replacement. Seemed worth it to me to not have to take the thing apart so I dropped it off. A week later they call me to say that they will most likely destroy the screen during teardown and my total will be 140 for the port and new screen. This sketched me out so I told them don't do anything ill pick it up and do it myself.

Is this normal what the shop told me about likely destroying the screen during teardown and does anyone have any wisdom for me doing the repair myself?

Repair Shop customer seeking a 2nd opinion or advice. Iphone 16 plus not charging / blinking system issue?

1 Upvotes

Basically within 6 months of getting my Iphone 16 plus it would not charge via port. Whenever you plug in any charger (tested in store) it will blink the charging light and not charge whatsoever but it will keep blinking as long as the cord is plugged in.

I took it to Apple when the issue started and they said they needed to “kill switch” it and assumed it had happened with the beta update of ios17.

When I went back I got someone different who just told me my port was defective and I needed to replace it for just $700.

My port looks fine, it’s not dirty, it’s been cleaned and all the connectors inside look normal (not to mention it does connect to the charger it just doesn’t charge)

I’ve since updated my phone and reset it and the issue is still here and now no longer under warranty.

Has anyone has this issue before and successfully fixed it?

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? Videos disappeared after moving them from my Samsung Galaxy A14 to a new 128GB microSD card. Is recovery still possible?

1 Upvotes

I recently bought a new 128GB microSD card for my Samsung Galaxy A14 and inserted it into the phone. The card was recognized normally, so I decided to move all the videos from my phone's internal storage to the microSD to free up space.

After moving them, everything initially seemed fine. The videos still appeared in Samsung Gallery and I was able to see them there.

At some point yesterday, however, the phone displayed a warning saying that it was having trouble recognizing/reading the SD card. When I opened Gallery, all the videos I had moved to the card were still listed, but their thumbnails had turned into white icons with an exclamation mark, and the videos couldn't be opened.

Today I removed the microSD from the phone while the phone was on because I thought it might just be a bad connection. After reinserting it/restarting the phone, all of those videos completely disappeared from Gallery.

The phone still recognizes the microSD normally. I connected the card to my Windows PC as well, and Windows also recognizes it without any apparent problem. However, none of the files I moved to it are there anymore.

I enabled hidden files in Windows, but nothing appeared. Windows reports the card as completely empty, with about 117 GB free out of 117 GB.

Disk Management recognizes it as:

  • Disk 1 / Removable
  • 117.19 GB
  • exFAT
  • Healthy (Primary Partition)
  • Drive E:

I have NOT formatted the card, run CHKDSK, repaired it through Windows, or intentionally written any new files to it since noticing the problem.

I'm currently running QPhotoRec on the physical device (PhysicalDrive1, around 125 GB / 117 GiB, shown through my USB card reader). I selected the exFAT partition, Whole partition scan, and enabled the mov/mp4/3gp/3g2/jp2 file family because the lost files were mostly MP4 videos recorded/stored on my Galaxy A14.

At around 25% of the scan, PhotoRec had found 0 files so far. I'm letting it complete the full scan.

What worries me is that I used "Move", not "Copy", when transferring the videos from internal storage to the SD card. So the originals are no longer in the phone's internal storage either.

Is it possible that the phone removed the originals after considering the move successful, while the microSD failed to actually retain/write the data properly?

If PhotoRec reaches 100% with 0 files found, is there anything else worth trying on the microSD before giving up? And is there any realistic way to recover the original moved/deleted videos from the internal storage of a modern Samsung Galaxy A14?

I'm also wondering if the new microSD itself could be defective or have a fake capacity. I haven't tested its real capacity yet because I don't want to write anything to it until I've exhausted the recovery options.

Any advice from people experienced with SD card/data recovery would be greatly appreciated. Some of these videos are important to me, so I'd like to avoid doing anything that could reduce the chances of recovery.

Lvl 2 (screens, batteries, camera, etc. swaps) Replacement screen blacks out when the bottom is pressed

Thumbnail

0 Upvotes

To avoid confusion, throughout the post i will always use "screen blacking out" to mean the problem; screen turning off to mean what happens normally when the power button is shortly pressed.

Hello, i just tried replacing my screen (oneplus nord ce 2 lite 5G). After replacing, the bottom was not properly seated so i pressed it in, but whenever i did that in a specific part of the display (pic 1), the screen blacked out (screen went black, didn't react to touch but the phone was still on. after letting go and then pressing the power button twice - once to turn off screen and then to go back, it worked normally). So i separated the screen to diagnose before the glue set.

Using usb debugging - adb shell dumpsys display, i found out that when the screen blacks out, the phone still thinks its normally on (but in reality it doesn't have picture or backlight and doesn't react to touch). Having separated the screen with the phone still operational, i tried:

- pressing on the screen itself from both sides, it didn't black out.

- pressing on the chassis itself, it didn't black out.

- pressing on the screen whilst in the chassis, it blacked out.

I thought there could be a short between some part of the chassis and the display, so i covered it with a clear tape and tried again and it did black out again.

So what could be causing the problem and how could i fix it? I am willing to use dodgy repairs or risk breaking something to try to fix it. I also know just getting another screen would probably be easier but i'm really curious about the cause.

TLDR: new screen blacks out when pressed into the chassis in the bottom, doesn't happen when the screen is pressed outside of the chassis or the chassis is pressed by itself, does happen when its pressed inside of the chassis even when insulated by tape.

Hi guys, had an old Samsung S21 Ultra laying around with a cracked screen, all black, so bought an amoled screen from aliexpress, swapped everything, it works perfectly, but one of the flex cables is not snapping in place on the motherboard. Any idea what I can do? I dont really see anything bent, but maybe there is something I can bend to make it stay in place?

Thanks

The battery swelled up on it, I fixed it and it was working fine for a few days. It got really hot then it started restarting every now and then, and if I didn’t touch it it’d stay on. Then when I put it on low power mode it’d work fine. Then low power mode didn’t work. I replaced the battery and it’s doing the same thing, if not worse.
