Preasure Sensor Test. What is your result?

[SGS7]

Hello World! So S7 is my first Samsung Device and I want to compare the pressure sensor aspect with someone who also has the S7 as I think either my new S7 is not water resistant or the sensor may be defective?

I am coming from a Sony Xperia line where there is a test to see when pressing down on the screen, the pressure sensor goes up, indicating the phone is water resistant. When I do the same test on the S7, the pressure only goes up by 0.1 or 0.2 point not 2.5 to 3.5 points I get on my Sony. I am wondering if my S7 phone has an issue with water resistance, bad sensor, or if this is 'normal' for Samsung.

If anyone of you can load the CPU-z app and look at your Pressure sensor and let me know what happens when you press on the screen, that would be help me troubleshoot it.

Thank you!

From what i know, the pressure sensed by the screen has nothing to do if it's water tight or not. I don't see how a higher detected pressure from pressing on the screen would indicate water resist.

Higher pressure = the seals are working. If the pressure does not rise the seas that waterproof the phone are not doing their job. Do you have CPU-z (free app), if so try it and let me know what is your result. Takes one second.

No that doesn't necessarily mean that. The pressure sensor is inside the phone, and only senses the pressure inside the phone. If the body of the S7 is more rigid that that of the Xperia, the pressure you exert on the screen will not increase the pressure inside that much, hence it's useless to compare pressures.

SGS7 is correct. If a phone is sealed, and you press on the screen, the screen will flex inward and raise the pressure in the phone. That's how a barometer (mechanical) works.
Which CPU-Z app are you using? There are several of them.

That is why I am asking to have someone else test it on a S7 so I can compare my results to validate them. Give it a try and report back.

I am using CPU-Z by CPUID Tools but you can use any one that you have to see if the pressure goes up and by how much.

Well I get pressure changes of 0.1 only

From my understanding the phone is not a completely sealed unit. The speakers are water sealed via a membrane that is finer than the viscosity of water. That's why it's only ip rated to a certain depth in cold water. Air has less of problem getting through the membrane.

Using CPU-Z, I get a change of 0.1hPa, then it returns to where it was.

It's amazing what these phones do. I used to repair/service recording barometers. Paper chart with an ink pen. Ink all over your fingers. I don't miss those.

0.1 increase here as well. I have never tested my phone underwater and I'm afraid to do so

Thank you all! This puts my fear of a defective seals away since I now know this is 'normal'!
