I’m asking specifically about iPhone 13 Pro Max replacement screens, especially Soft OLED screens.

Can anyone who has installed or is currently installing a Soft OLED screen test it with a Multi Touch Tester app and confirm the maximum number of live touch points?

I want to know if it detects only 5 fingers or if it can detect 6 or more fingers at the same time.

This is not about PUBG or any game. I’m only asking about the actual screen touch capability using Multi Touch Tester.

If you have tested it, please mention:

1. Screen type/brand: Soft OLED / GX / DD / X07 / other
2. iPhone model: 13 Pro Max
3. Maximum touch points detected
4. Where the screen was purchased, if possible

Please reply only if you have actually tested it or can test it now. Thanks.

Over time it became:

• white screen
• occasional recovery
• then reboot loops with pink screen flashes before shutdown

A third-party shop replaced the display with a non-genuine screen. After that:

• phone rebooted every ~5 mins
• then eventually stopped turning on completely

Apple checked it and said:

• connectors looked fine
• no obvious tampering
• but they could not power it on

Phone still warms slightly while charging.

Does this sound more like:

• OLED/display failure,
• battery/power management,
• or board-level issue?

Has anyone seen similar 13 Pro Max cases where the data was still recoverable?

I ordered and changed my ear speaker for my 13 pro max because it was super quiet and hadn't gotten better even after cleaning it. After i replaced it didn't work as all anymore.

Going back to the old original post asking this same question; someone commented to replace the WLAN card because that is the connecting piece for the ear speaker to connect to the logicboard. I followed those steps, ordered a new one and am still having the same isse.

My questions are: what other functions run through the WLAN card that I could test to see if the connector to the WLAN card might be the issue?

And if I am able to diagnose the card either as working or not, what would be the next best step to get the phone fixed? What kind of repairshop can fix or diagnose things like this on a deeper level, and how likely is it that its an issue with the audio chip or something else thats harder to fix. And is it even possible to fix this?

Any help is incredibly appreciated!

Because Stolen Device Protection is enabled, some of your account information can't be changed on the web. To remove a device from your account, use your Apple devices where you're signed in with your account in the Settings app.

And my iPhone is in DFU mode so I can't turn it off either. How do I fix this? =/

I checked for software updates and try turning off the phone then back on and the problem still did not go away.

Any suggestions?

The LCD comes with the easy flex for transplant the LCD IC, I have the tools to make it, my question is: If I transplant the IC do I still need to program the true tone or that data is on the IC itself and not required when transplanting IC?

If it is required to program the true tone anyway, can I still read the original value from the original LCD without the IC on it?

Quick question: on the iPhone 13 Pro Max EU version (no Ultra Wideband), does the top-left antenna module (the one by the internal earpiece) handle Wi-Fi, 4G, and 5G, basically all cellular functions?

Thanks!
