Samsung was one of the first OEMs to start rolling out the latest Android 12 and it did so soon after Google. It released One UI 4.0 for all premium flagships including foldables but unfortunately, many users ended up facing performance issues. This forced the company to hit the pause button and suspend the update release. It seems like everything is back in order as the South Korean giant is getting ready to resume the process.
One UI 4 based on Android 12 has reportedly begun arriving for some Galaxy S21, Galaxy Z Flip 3, and Galaxy Z Fold 3 users. The new firmware has G99xBXXS3BULC, F711xxxS2BUL6, and F926xxxS1BUL6 build numbers respectively. It is an over-the-air update that should become available on your particular device anytime soon. You can also check for the update manually by visiting the system settings.
The original report was said to be affecting devices in various ways including even bricking some foldable units. Other reported issues were related to the screen flickering, dark mode, and sluggish performance. Samsung has teamed up with Google to fix these issues as they were found to be related to Google Play incompatibility.
Here is the official statement from one of the Samsung Community moderators (translated using Google Translate):
"Samsung Electronics is committed to customer satisfaction and consumer protection. After the One UI 4 update, a problem was found due to compatibility issues with the Google Play system on some devices, so the One UI 4 update has been put on hold for a while. We are currently taking action after analyzing the content with Google. We plan to redistribute the One UI 4 update after securing the stability of the device and completely solving consumer inconvenience and errors. We are currently preparing a revised version of the software, including a Google patch that improves compatibility issues, and testing is in progress. We will do our best to finish it well as soon as possible so that stable software can be distributed."
