iPhones feature a number of sensors, which are used to adjust the screen based on operating conditions, enable motion-controlled games, location-based services, unlock the phone, and authenticate purchases with Apple Pay, among many other things.

Here are the sensors …


Audio input, Proximity sensor, Ambient light sensor, Water damage indicator, Barometer


Accelerometer, Magnetometer, Gravity sensor, Gyroscopic sensor


Fingerprint sensor or Camera for facial recognition

and last but not least the Accelerometer part of the device-motion information .

The 3-axis accelerometer senses the orientation of the phone, forwards it to iOS which then changes the screen accordingly, allowing the user to easily switch between portrait and landscape mode. Unlike the iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so.

Your Google+ app doesn’t support screen-rotating so you can easily read the twisted message at the top of my post.

For the nerds who like to control everything the app Sensor Kinetics by Innoventions Inc, available at the App Store, might help.
