OPPO A52 has already received the Android 11-based ColorOS 11.1 update in January 2021. After that, the good thing is OPPO started rolling out a new software update for the device with a new security patch and fixes.
According to the latest report, the April 2021 Android 2021 security patch update released with several fixes like camera, system, and more. The update fixes an issue where the preview of a photo you had just taken would not load, a freezing issue that would occur when you adjusted AF in EXPERT mode to take a photo.
Additionally, It fixes an issue where you would occasionally be unable to pull down the notification drawer when playing games in landscape mode, an issue where you would be unable to bring up the virtual navigation buttons by swiping left in a game, and an issue where charging would be slow in certain scenarios.
A new firmware update, which bears firmware version CPH2061_11_C.28, is now rolling out in India and Indonesia. Apart from the April 2021 security patch, we can also expect the update to bring non-critical bug fixes and stability improvements to the smartphones.
If you owner of OPPO A52 in any of the countries mentioned above, you can manually check for the update on your phone by navigating to Settings » Software update and tapping on Download and install.
