This afternoon, Samsung Galaxy Galaxy official Weibo released an announcement, officially announcing the Bank of China One UI Beta plan. Samsung Galaxy S20 | S20+ | S20Ultra will start testing One UI 3 in mid-to-late October. One UI 3 is based on Android 11 that was just released not long ago.
If you own the above three models and have already unlocked them, you can register on the latest version of the "galaxy community" APP. The specific registration time and test time have not been announced yet.
The Samsung Galaxy community officially stated that the test version is not an informal version, so it may cause some malfunctions and some functions may not be available. Before installing the One UI beta, you need to back up your data. If you want to exit the test after the upgrade, you can exit the internal test activity through the Galaxy Community, reinstall the official version, and install the backup data through the replacement assistant.
Currently, One UI 3 has been tested in some markets such as the United States and South Korea.
