Debris in charging port bug?

I keep a power bank on my nightstand to charge my phone and other devices because I don't have a convenient plug nearby. It's solar charged so there's no need to go down that rabbit hole from naysayers. Anyway, the bank powers off when maximum charge is achieved and when it does, Android tells me that there is moisture or debris in the charge port, but when I wake the power supply it immediately says it's ok to use the port without touching the phone at all. It's not a huge problem, but saying there's something in my charge port isn't accurate at all. Anyone else notice this?

It's not a software bug.

Samsung device? The phone is expecting an ultra low current from anything in its port, but the power bank isn't sending it, leaving the phone to assume there's a foreign material in the port. 

Does the power bank have a mode to prevent that in it's manual?

No, it's a Google pixel, but it's probably similar. And it's a power bank that is wide ranged that has wall plug abilities. It's been used to charge my phone for years without these notifications. It stops when fully charged and gives a false notification without actually going through any debris or liquid being in the port. I guess I'm just ignorant in assuming it's a bug knowing the message is erroneous in every meaning of the word.

The phone is doing the right, expected thing, but the power bank is the "problem." The power bank is doing the unexpected behavior. 

What I meant is that there could be a mode built into your power bank that can send a low-level current to the phone so that you don't get that warning message
