It really depends on the model, manufacturer, & luck. I’ve never had a phone lose its water resistance. The phone I use today (a 13 mini) is almost five years old and I clean it by running it under the faucet.

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'd return it if a brand new device that advertised IP67 died almost immediately under a normal sink water flow. Clearly it wasn't built to spec and one can't trust the rest of their manufacturing.

But I mean that's just similarly true of Samsung products. I avoid them like the plague. I haven't had a good Samsung device in almost 20 years, and used to be a Samsung fan

They said 2 years after purchase. So that's where the debate is. How long should we hold manufacturers accountable for in regards to waterproofing? 1 year, 2 years, forever?

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.

I just put my Pixel 10 through the washing machine by accident. To my surprise, it was perfectly fine.

I definitely don't mean to call into question Pixel device robustness overall into question. I'm just trying to point out even well glued phones eventually develop weaknesses to their seams. And this was a device I routinely washed iin the sink to clean, it really caught me off guard when it failed.

"Yes, when you buy it, no after 3 years when the glue that waterproofs no longer sticks due to ageing."

My 2014 Kyocera Duraforce Pro is STILL waterproof and I use it for underwater photography incessantly.

I'm kinda surprised with esim, wireless charging and Bluetooth noones just made a phone with a solid layer of glass completely surrounding it for 100% waterproofing

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.
