For the fun of it, I downloaded the app on my phone to compare results. My readings match those on the left (top). There are several sensor IC’s inside the iPhone. * Compass IC * Barometer IC * Accelerometer & Gyroscope IC * Motion CPU They are all powered by the same voltage rail so multiple failures may point to a voltage issue. The Gyro IC is also sensitive to water, whether it be water damage or ultrasonic cleaning. At this point, you may want to have the phone looked at for some board level diagnostics.
