Samsung’s rollout of One UI 7 based on Android 15 continues. Today, the new software has made its way to the Galaxy Z Fold4 and Galaxy Z Flip4 in Europe, after having initially been graced with it in Korea last month.
The European update arrives over-the-air as version F721BXXUAHYD9 for the Flip4 and F936BXXUAHYD9 for the Fold4. It’s a 4.5GB download for the former and 4.6GB for the latter. With that in mind, make sure you have a good enough data connection before you proceed.

The update for both devices includes the April 2025 security patch level. As always, the rollout is likely to be staged, so not every Flip4 and Fold4 handset in Europe will get it at the same time. If you’re impatient, you can always manually check for the update on your phone by going to Settings > Software update > Download and install.
