Dopo l'installazione, il dispositivo ha iniziato a riavviarsi da solo frequentemente e a bloccarsi in modo casuale.

Ho già effettuato i seguenti controlli:

1. Verificato e pulito i connettori del display con alcol isopropilico.

2. Controllato che non ci siano pin piegati.

3. Escluso altre cause hardware comuni.

Qualcuno ha riscontrato problemi simili con i pannelli LCD In-Cell su iPhone 12? Potrebbe trattarsi di un'incompatibilità software o di un difetto specifico del componente che richiede una sostituzione in garanzia? Grazie per l'aiuto!

Da subito ho notato che il telefono si surriscalda più del solito e in pochissimi minuti, soprattutto nella parte inferiore del display.

Inoltre anche la batteria si scarica più veloce rispetto a prima. Un installazione fatta male o un display scadente possono effettivamente portare danni alla batteria? Sono consapevole che il display non è originale ma non so se c’è una correlazione

About 4 months later the screen started to flash intermittently and the touch screen would become non responsive. From talking to folks, it sounded like it needed a new screen, so I ordered one. I took off the old screen using the ifixit.com video. Partway though I noticed the video and photo guide mentioned steps to remove a panel and a cable that attached the camera/mic/speaker assemble, but the unit I was repairing didn't have that assemble attached to the screen. I continued on and when I unpacked the replacement OEM screen, I found the OEM one had tabs on it, and screw mount points for the camera assemble I mentioned. The old screen had none of this, and the tabs won't fit into the body of the iPhone. I also noticed the old screen didn't have the two tabs towards the bottom that the two pentalope screws go through when you first start to take it apart. I did power up the unit after I attached the OEM screen and it works, but I wondering what the deal is with the differences in the screens. I checked the other iPhone 12 models but the base model i have does match most of the repair guide layout, but I cannot use the OEM screen. I'm going to try and get the serial number to confirm this is actually a real iPhone and not a counterfeit. Has anyone come across this before? Here are a couple reference photos. The old screen (I ended up breaking it while removing it) and the OEM one attached, the red circles show the camera assemble screw points, which are not on the removed screen.
