本体の左下に体重をかけてしまい、画面が少し割れました。

その後タッチセンサーが全く反応しなくなりました。

タッチが出来ない以外は問題が無く、通知は表示されます。Bluetoothを繋げばイヤホン操作で電話も受け取れます。

このiPhoneを正常に動かす為には画面修理が必要ですか?それとも基盤の交換が必要ですか？

Does anyone know what this plastic piece with the white squares is for? I noticed it was missing while assembling the phone, and everything works fine once it's assembled, so it's apparently not necessary, but what is its purpose?

Today I was taking a picture at a white background and I noticed this dark shape on my camera. I thought that it was dust or something on my lens and cleaned it carefully with some cotton and some cleaning substance for lens and they looked clean with no scratch or anything. When I opened the camera app again, the spot was still there. I never dropped my phone in water or anything. I dropped it from like 40cm on its face, but it's been like a month since then and i checked my old photos. The spot wasn't present.

Definitely it's something in there. When i zoom in, the spot gets bigger. When i zoom out, it immediately disappears, no matter the zoom out value under 1. Also, in portrait mode the spot isn't visible.

What can it be? A friend of mine told me that it can be a software problem but i doubt…

Thank you!

It feels like something is loose in there. And when it doesn’t connect, a good smack of the phone downwards into my palm can do the trick. Also, the lightning cable can just kind of slip out, like it’s not catching in the receptacle.

So, what do you think is going on?

I have an iPhone 12 Pro which is in the process of getting the back glass off, however this process has taken some time. I currently have all the components in a tray and will be putting it back together soon, but before I do, I wanted to know what was the bare minimum components I needed to get the phone to turn on. This is so that I can add components back in one by one, and be able to identify any faulty components. I would assume battery, charging port, motherboard and screen, but please advice me on this matter.

Thank you

The process seemed to go fine, and Face ID was still working after the new battery was installed. I tested it a few times before closing up the phone, and everything looked good.

But once I closed the phone completely and powered it back on, Face ID stopped working. When I try to set it up now, it just tells me to “move iPhone a little lower” or “move closer,” but it never actually detects my face. The proximity function is still working, so it couldn't be that. I tried running the apple diagnostics, and it said that the True Depth sensor had the problem.

I didn’t mess with the Face ID components during the repair, so I’m not sure what happened. Is it possible something got slightly misaligned or pinched when closing the phone? How could it happen? What should i do now and the next time?

Any help would be appreciated.
