Will a broken fingerprint reader mess up an s9 going underwater

[Al Red Hornbeam]

Found an s9 for sale has a broken fingerprint reader will that un do the ir rating . I spend a lot of time in wet places so that's a deal breaker if so.
Thank you in advance

Even if that specifically isn't voiding the IP rating, it could mean the phone was abused and I wouldn't trust it. If there is any physical damage, all bets are off.

Then again, I don't trust those ratings to begin with. If your phone is at a large risk of getting wet and you can't leave it behind, I would suggest keeping it in a bag you can seal air tight.

 

[me just saying]

since the sensor is exposed, it could also mean anything it is connected to is exposed. I can understand getting a cheap, used phone for working in damp or wet enviroments but in this case, it would be a deal breaker to me. If you decide to go ahead and get it, I would cover it with duct tape.

I also agree with the previous post, it would be hard to break the covering of the fingerprint sensor without other possible, abusive damage.

Thank you everyone. I contacted support at Samsung they informed me that with any kind of crack the phone is no longer water proof

To be fair, no phone is waterproof. At best, it was water resistance based on controlled lab tests, and I've yet to hear of any manufacturer that will warranty a water damaged phone.
