The situation has probably happened to you before. You are lying down, you grab your phone to reply to a message and the screen rotates to landscape mode when it is no use. The next version of Android wants to fix this modern day problem.
The next version of Android will make life easier for those who use their phones in bed. The future Google OS will automatically detect the way you are installed when you consult your phone. If you are lying down, your phone will automatically turn off screen rotation.
The idea of this ” better and faster autorotation mechanism According to Google, is to prevent the phone from going into landscape mode when you are lying down and holding your device at 90 °. Until then, Android phones had relied on their accelerometer (a small tilt-sensitive component) to determine whether to display their interface in portrait or landscape mode. With Android 12, phones will also be able to rely on another data: facial detection.
What about privacy?
Already present in the latest beta version of Android, this feature will actually use the front camera to determine what position your head is in. If the phone detects that your face is at 90 °, then it will stay in portrait mode so as not to spoil the experience. No more manually blocking screen rotation when scrolling to Twitter in bed.
Well aware of the privacy issues attached to all facial recognition and detection functionalities, Google ensures that all these calculations necessary for the proper functioning of this functionality are carried out locally on the phone and ” that no image is ever saved or shared by the device “. Everything happens within a dedicated Android partition, the Private Compute Core.
Announced during the presentation of Android 12, this feature creates a secure space on the phone, dedicated to the processing of personal information. Rather than sending your data to Google’s servers to take advantage of their computing power, the Private Compute Core performs machine learning tasks locally, using the computing power of the phone.
Nothing is sent to Google
It is this feature that allows your mobile, for example, to offer automatic replies to some of your messages or to create automatic subtitles on certain videos. All data is analyzed directly by the OS, in a locked space, inaccessible by the rest of the system. The same will be true of the facial detection data that powers the new intelligent screen rotation mechanism.
In its blog post, Google also claims to have made the screen rotation 25% faster thanks to system optimizations. Soon the end of screen rotation problems?
