Android “Pie” (codenamed Android P during development) is the ninth major release and the 16th version of the Android mobile operating system.
Android 9.0 Pie key features
Accessibility Menu: With Android 9’s new accessibility menu, common actions like taking screenshots and navigating with one hand are now easier for motor impaired users.
Select to Speak – OCR in Camera View: With Select to Speak, you can select text on the screen and the content will be read aloud. Now, Android 9 has added added OCR support for S2S in Camera and Pictures to make text even more accessible. Simply select text when using the camera or in picture, and the text will be highlighted and read aloud.
Sound amplifier: This new Accessibility Service makes it easier to understand conversations by dynamically adjusting over 100 settings to boost the audio in scenarios such as a loud restaurant, bar, or concert.
Battery & Brightness
Battery Saver: Battery Saver keeps your charge going longer than ever by turning off features like the Always-On display. Plus, you have more control over when it comes on – so you can go further on one charge.
Adaptive Battery: This feature uses machine learning to predict which apps you’ll use in the next few hours and which you likely won’t, so your phone only spends battery power on the apps you care about.
Adaptive Brightness: With Adaptive Brightness, your phone learns how you set your screen’s brightness in different lighting environments and automatically does it for you over time.
Background restrictions: Now, you’ll see recommendations in Settings to restrict certain apps that use too much battery, so you can have more control over your battery.
Multi-camera support: With Android 9, developers can now create immersive experiences using streams from two or more physical cameras, such as on devices with either dual-front or dual-back cameras. Examples include depth, bokeh, stereo vision, and more.
External camera support: Android 9 now supports external USB / UVC cameras on certain devices.
Display cutout: Support for devices with cutouts to make use of available screen space.
Edge-to-edge screens: Support for devices with 18:9 and taller aspect ratios, and devices with display cutouts.
Notification enhancements for messaging: Now, messaging apps can provide suggested ‘smart replies’ in the notification, so you can respond in a tap. Plus, any inline reply drafts won’t disappear if you navigate away, and you’ll be able to see images sent from your friends right in the notification.
Manage Notifications: You now have a quick way to turn off notifications from a range of apps, so you only receive those that are helpful to you. You’ll also get a smart prompt if you’re swiping away certain notifications whether you want to keep receiving them.
