Samsung A20 Android 10 update is now available in many countries, including Russia, Vietnam, Chile, and the Philippines. The anticipated update for the Galaxy A20 comes with the April 2020 security patch level and all Android 10 One UI 2.0 features.
As expected, the Galaxy A20 didn’t isn’t directly jumping to One UI 2.1. Being a budget smartphone, it probably won’t get One UI 2.1 bump until the Android 11 update comes along. That’s likely going to be the case of all the mid-range and budget smartphones.
