hello there,
***AOP NMI POWER (Non-Maskable Interrupt)*** [br]
Type of IRQ interrupt with extraordinary allowances. It has priority in memory shares and the right to interrupt lower-priority broadcasts. All indications are that it is being considered with the AP.SEP "Secure Enclave" mechanism, the Face.ID front sensor assembly and the front camera.
Everything points to a short circuit. The reason for this can be really different: from liquid dammage, through an unauthorized and sloppy repair attempt to incompatibility of the IOS version (which also happens sometimes). I described the problem on my blog. Search, read, you will understand.
