Samsung and Huawei already have optimized their flagship smartphones as "minicomputers", seeing as how they can be connected to the PC monitor effortlessly. And, the latest of them is something that will allow you to use your smartphone as a Bluetooth keyboard or mouse. Instead, Google chose to surprise everyone with an unexpected Android P release on Wednesday, and Android fans spent the rest of the day checking out all of the new features baked into Google's newest OS.
Requiring root to use this feature makes it hard for a vast majority of users. Today, we're also confident that Android P will finally add support for the Bluetooth HID device profile service, which will allow for your smartphone to be used as a Bluetooth keyboard or mouse. Once the required Bluetooth code is enabled in stock Android natively, you won't have to root your phone to use your phone as a mouse/keyboard.

We're halfway through the Champions League second round and thoughts are already turning to the quarter finals and who will play who.
A patch adding support for the Bluetooth HID was committed in 2016, but the functionality was disabled for future Android releases. Implementing the Human Interface Device (HID) Bluetooth profile allows for input devices such as mice, keyboard, joysticks, and more to work. It was quite the breakthrough, but of course, seemingly never legitimized or supported by Google and the Android team.
This feature might offer a way to control workplace presentations or could act as a media remote. This new feature is a step forward in expanding the inter-connectivity between the smartphone and other devices. The first smartphones to receive this feature is probably the next Google Pixel series this year, so we will just have to wait and see.
