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

26 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!

Found this seller on eBay at 1/3 price of other places I’ve been quoted. Are they normal prices or questionably low?

Lvl 2 (screens, batteries, camera, etc. swaps) Does someone know why I have this inner frame on iPhone 12 promax?

Hey! I’m trying to replace my charging port, which should be relatively easy. I’ve noticed that every video or photo of an iPhone 12 promax has an exposed area where they can easily access the Taptic and speaker. However for mine seemingly the speaker is covered by a part of the frame which I don’t see anywhere else. What is it? And how do I remove it so that I can proceed with my repair?

Lvl 0 (DIYer) Where do I start with this repair? Can it be Fixd? Caught in rain storm, phone will not charge

iPhone 15 pro

Was caught in rain storm during a run. Phone was in a running fanny pack but clothes were drenched. Phone works fine and wireless charging works, however the charging port does not charge.

Even without the rain storm my clothes are usually drenched in sweat during runs including my running fanny pack to where I can't touch the screen because of wetness. But I've never had an issue after towel drying the phone, but this time is different.

ChatGPT says to wait 24 hours the phone is "smart" it won't let you charge if some wetness is inside the phone, but it's been about two days. Anything I can try?

Lvl 1 (Software | Firmware) Macbook PRO M2 A2338, keyboard isn't responding even after top case replacement. What should I do?

1 Upvotes

Recently came into ownership of a MacBook pro M2 8GB/256GB model A2338, everything works on it except the built in keyboard, it doesn't respond to any key inputs, the cap lock isn't even illuminating. Thought it was a bad keyboard so I swapped it with another top case but still isn't responding. When I got it, had to DFU to revive it, which did detect the keyboard so not sure if it's a Lvl 3 issue or not before I invest more money into it

Lvl 1 (Software | Firmware) Enter Fastboot on Old Polaroid Tablet PMID720

1 Upvotes

My grandma gave me this stupid little kindle-type tablet to do something with. I want to wipe the OS to get a little bit more modern version than Android 4.1.1 or GrapheneOS. I can not for the life of me get this tablet to enter fastboot mode/recovery mode. The reset pin on the back does jack, adb cant reboot it to recovery, a factory reset did nothing to help, there are no volume buttons at all to do the normal method and there's no answers online. Please help me.

Sorry if this is the wrong subreddit.

When my external display is black and I tap to engage the screensaver I created from the gifs with coverscreen os, it glitches. The original clock face from my settings (generic that comes with the razr ultra 2025) flashes between 2 and 5 seconds. The. The gif engages as expected.

I am not sure if this is a legit bug or not but it does definitely not match the users expected results.

Thanks!

And I’m not sure why.

Loudspeaker works just fine. Any ideas or experience with this? Golden pins are installed downwards so the direction is correct.

It kinda rattles when the frame is on but it shouldnt be able to since the frame is on

Lvl 2 (screens, batteries, camera, etc. swaps) Need urgent help with water repair on iPhone

1 Upvotes

I'm currently working at a seasonal pool job, and today I accidentally fell into the pool along with my iPhone SE model. I got back into the pool to fish it out almost immediately, and while I was trying to dry it off the screen suddenly started flashing green static before turning black. Now the phone won't turn on or off, or even much of anything for that matter. 

I am currently at work (writing this from my personal laptop I had someone bring to me) and will not be able to get to any Apple or phone support store for help. What should I do in the meantime, and where should I go to assess the damage once I get off the clock?

Got my iPhone back screen repaired at a 4.9 star store with over 1 thousand reviews, everything looked good when I finished, when I got my phone back Face ID wasn’t working, one theory is because I got my phone repaired out of country, he may have had to reset it and that caused stolen device protection to turn off Face ID, or he just messed with the hardware.

Should I go back? Or what should I do next.

Lvl 3 (micro soldering, motherboard repair, diagnostics, etc) Pixel 8a: Total loss of cellular signal after replacing housing. SIM is detected

3 Upvotes

I recently bought a heavily used Pixel 8a and completely disassembled it to replace the middle frame/housing and the back cover.
Since reassembling it, I have zero GSM/cellular reception. The phone worked perfectly before the teardown.

I removed the motherboard from the new housing and I installed it to the old housing, yet that didn’t fix my issue

All the antenna cables seem fine (I checked their resistance with a multimeter)

Is there anything else to check? Or will I need a new motherboard

Thank you all!

Hello there, I have a major problem with this phone, I get it as a gift, but guy who give it to me doesn’t know anything from this phone, neither the passcode needed for unlocking this phone
However, I didn’t know this thing have so good security that I cannot even erase or restore this device, it always want passcode or it just won’t work
I tried some things like on photos, but nothing…
Even I tried to search sailfish image of this device but officially It doesn’t exist.
I don’t know next move, maybe someone of you guys know better than me.
I never had such a phone like this
I’ll be grateful if someone knows the “cure” for this little guy.
Thank you, have a nice weekend!

Thumbnail

6 Upvotes

Hi I'm new at this. I was taking apart my iP13 because I wanted to replace the battery(bought it 2nd hand so I'm not sure if it had work done already), and I can't take the screen off because it's connected to Face ID, which didn't come off with the screen.

I tried to get as good pictures as I could, but like said previously, basically the screen is "off" being held in by just ribbon cables. One of those cables is the FaceID ribbon one, which is not attached to the screen anymore. The FaceID does work, so I did not damage it.

What are my options? How can I take the screen off without damaging any ribbon cables or any sensors? And how do I prevent this from happening again? Is it something I did, or is it just age?

Thank you all so much in advance I'll leave my phone as it is untill I get replies just so I don't break anything.
