I cleaned a Samsung A53 under the faucet about 2 years after purchase brand new, using only a little water.

It failed soon after from water damage. I had to get it dried out and a new screen fitted, and some functions never worked properly since then.

I expected better as the specs claim IP67 ("Submersible in up to 1 meter of fresh water for up to 30 minutes"), and I used only a little water.

I had a Pixel 6a last year bought not too long after it came out. I left it on a patio table. I was hosing things off and there was a significant amount of over spray on to the table. The screen died over the course of a couple of hours due to water ingreess.

all that water is keeping the glue moist

A lack of physical port makes troubleshooting more difficult. Apple didn’t remove the diagnostic port from their watches until the series 7. Also I think certain governments require that phones have a USB-C port.
