Hello
I just got a brand new iPhone 8 plus.
I check the pressure and I found an error of more than 2 hPa no matter what app I try.
2 hPa is about 20 meters high...
Is it possible that the iOS version 11.0.3 is responsible of the bug ?
I try to contact Apple Support but they don't know about barometer.
They tell me to go in an Apple Store to check hardware...
Do you check you barometer ?
Are accurate ?
My older phone is an iPhone 6 plus and the barometer was accurate by 0,2 hPa...
My Watch 3 is also very accurate !
