what is irq/464-14c2000 android
The only place I've seen mentions of something like this: XDA-Developers

From the names of other items, it looks like it's indeed the interrupt request (IRQ) from various hardware (you can see flip cover, sensor, NFC, power management IC (pmic), etc.), but there are ones with similar cryptic numbers whose purpose is unknown to me.

My advice? Just ignore it.
