I am trying the pressure test with pressure sensor to test it's waterproofing or not The value doesn't goes up when I press the panel and the value dropped by one when I release Then when I hold the three holes at the bottom and press again, the value goes up by 5-6 It is normal the value doesn't raise if I didn't close the three holes?
If you want a reliable pressure test the only way is to send in the phone to a service center. The phone should however be tested from factory so if it's new it's not necessary to test.
