iPhone 12 Pro: Problema alle fotocamere iPhone 12 pro

Sat, 20 Apr 2024 01:21:06 -0700

Salve a tutti.
Vi pongo il mio problema, sto aggiustando un iPhone 12 pro che in seguito a caduta presenta (oltre che la rottura del display) problemi alla fotocamera posteriore e frontale che non funzionano , schermo totalmente nero, nemmeno un input di scatto ,niente, non solo queste ma anche il flash e il Face ID non vanno più, aprendolo i componenti sembrano perfetti senza alcun segno di danni, essendosi molto danneggiato nella parte del Face ID pensavo si fosse guastato quest’ultimo e che mandasse in blocco anche le fotocamere ma con il programmatore qianly ho verificato che il Face ID è funzionante, a sto punto l’unica ipotesi che mi viene è che si tratti di un problema alla scheda logica..se sapete come confermare sto dubbio, anche eventualmente illustrandomi come verificarlo col tester fatemi sapere come si fa ; Premetto che ho già provato a ripristinare in tutti i modi iPhone e quindi escludere un problema software.
Grazie in anticipo per le risposte e buona continuazione!

iPhone 12 Pro: Dark spot on camera

Tue, 31 Mar 2026 11:41:11 -0700

Hello!

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!

iPhone 12 Pro: cyclic reboot every 3 minutes

Sun, 15 Mar 2026 08:53:20 -0700

Hi, my iPhone 12 pro reboots itself. I looked logs, it says that the thermalmonitord daemon did not respond for 180 seconds, and the system writes that it does not see the Prs0 sensor (it looks like a barometer). Has anyone encountered it? Is it being treated by replacing the cable or is there a problem with the processor?

iPhone 12 Pro: How to find the cause when Face ID stops working

Sun, 19 Oct 2025 22:06:13 -0700

I sometimes get iPhones where Face ID doesn't work, either after the front glass has been damaged or replaced, or for no obvious reason.

What's the best way to locate the cause of the problem — and is there any reliable method to make Face ID work again once it has stopped functioning?

iPhone 12 Pro: Reattach/replace lightning connector?

Sun, 21 Sep 2025 12:34:07 -0700

Connecting lightning cable doesn’t always charge. 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?

iPhone starts and operates but does not connect to cellular; run the 'finish repair' routine and it fails - will not allow the digital repair to work. Have been through the Shut Down / Restart to diagnostics routine a few times. This is my fifth iFixit repair and I believe it is installed correctly. Cannot iMessage, phone, etc.

iPhone 12 Pro: What is the bare minimum an iPhone 12 Pro can run on?

Sat, 23 Aug 2025 17:22:44 -0700

I'll try to keep this quick and short.

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

iPhone 12 Pro: Face ID not working after battery repair

Mon, 26 May 2025 08:19:35 -0700

I replaced the battery on an iPhone 12 Pro. 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.

iPhone 12 Pro: Phone doesn't charge after ifixit battery replacement.

Tue, 06 May 2025 00:23:57 -0700

So I ordered a battery and screen adhesive from ifixit so I can replace my iPhone 12 Pro battery.

At first boot with the new battery, phone reported black screen with "battery needs charging" icon. Alright, plugged it in and it started no problem. I read that sometimes the phone needs charging juice to turn on.

It turned on and reported 60% something percent charge. Alright, following the battery calibration guide on ifixit website and on the battery's box, I left the phone to charge until it reaches 100% and leave it charging for at least 2 more hours.

Done so and came back after 6 hours to phone stuck at 94% charge. Battery optimization was enabled at the time. There was no mention of this feature in the guide. I disabled battery optimization and put the phone to charge again. Came back after 2 hours and phone was still stuck at 94% charge?

I force restarted the phone while it was charging and it showed 98% charge. Cool. I'll leave it to charge to 100% then. Except... it didn't charge...

It stayed at 98%. I thought I would have to drain it completely and charge it back up so I started using it until it would shut down, no problem. Came back home and phone went to 0%. Cool. I left it to charge overnight and in the morning I woke up with 70% battery. When I unplugged it, the % started to go down about 1% every few minutes. Strange... Plugging the phone back in told me it was charging but the % was still decreasing. Force restarted again, it showed 94% battery and it started dropping fast again.

Now I'm in the situation where I think the ifixit battery is low on charge and the phone refuses to charge it. What else can I try? Is my ifixit battery DOA and I need to get a new one (and new screen adhesive)?
