One UI 3.0 and Their Expected Features
As the name suggests, the One UI 3.0 (Android 11) will be the successor of the latest generation One UI 2.0 (Android 10). Google has already released the 2nd Android 11 Public Beta build officially with the platform stability for the help of app developers. Next, the Android 11 official stable version is expected to release in September 2020 and we hope that Samsung will gonna release its first beta build of One UI 3.0 to Samsung Galaxy S20 units most probably.
The expected One UI 3.0 beta update recruitment may start in November 2020 and will be rolled out to the eligible devices in batches. It’s needless to say the One UI 3.0 will be inspired and based on all the native Android 11 features and other goodies. Here we’ve shared some of the expected features below.
Improved Gesture Navigation: With the One UI 3.0, users can easily configure and use the sensitivity of the back button or swipe gesture. Additionally, users can lower the sensitivity level on the left edge from the gestures option.
No Need To Unlock After Reboot: With the help of the ‘Resume on reboot’ option, the device apps can resume normally and receive messages after a reboot without unlocking the screen or giving any authentication.
View Current Refresh Rate: Google has finally included the option to see the current refresh rate limit on the screen if enabled by the Developer options.
Use Bluetooth Headphones In Airplane Mode: Unlike the previous Android OS, you can simply turn on Airplane mode along with the Bluetooth. That means even if you enable Airplane mode, the connectivity option like Bluetooth won’t turn off anymore.
Send Images In Notification Replies: You can now send images directly to the sender from the message notification panel easily. Simply choose Reply and you will be able to attach pictures in that conversation.
Additionally, the upcoming One UI 3.0 update may bring improved Keyboard transition, better foldable support, improved 5G support, Wireless debugging, and better support for waterfall display devices, improved app permissions for location & privacy control, improved dark mode, chat bubbles, improved call screening, improved screenshot management, and more.
