I was having a repair done. Initially, I didn't have any issues with the display, but the next day, when I reassembled the device, this problem arose where Dynamic Island isn't displaying correctly...

The center section between the cameras remains blank without the black auto-fill feature. Only two lines appear, one above and one below.

I just replaced the display on my iPhone 15 and noticed a bit too late that the replacement part did not come with a front sensor cable on it.

Neither the part description nor the repair guide seem to mention this. Is that expected?

I just replaced my slightly cracked screen by a LCD panel. After following the iFixIt tutorial (note: doesn't mention replacing the proximity sensor), I'm stuck in a reboot loop. The touch screen, FaceID and other functionalities seem to be functioning correctly besides that.

According to this thread:

https://fr.ifixit.com/Réponses/Afficher/...

it seems to be related to the SMC/TrueTone verification failing. Is this the issue ? In that case, would adding the proximity sensor back fix the issue ?

thanks in advance

Edit:

Here's the a couple of screenshots of the panic logs

The screen was a In-Cell LCD display according to the documentation of the product: iPhone 15 screen Fix Kit
