Galaxy Z Fold 4

The One UI 5.1 update for the Galaxy Z Fold 4 5G foldable smartphone comes with firmware version F936BXXU2CWB2. The package size of this release is over 2GB as there are several meaningful upgrades in terms of usability (multitasking) and visibility.

Samsung’s One UI 5.1 update carries PDA software version F721BXXU2CWB2 for the Galaxy Z Flip 4 in India. The firmware weighs about 2GB and includes a newer security patch alongside the new features such as the Battery Status Widget.

One UI 5.1 is a big deal, here’s why:

One UI 5.1 update is based on Android 13 OS and focuses on productivity and personalization enhancements. The new One UI version allows you to easily change the color tone of selfies, thanks to the Effects button placed at the top of the screen.

Samsung claims that it has worked on the Search feature of One UI and the 5.1’s ability is quite high as compared to the previous version. Similar to Google Photos, you can now search photos of people by just tapping their faces as well as the ability is added to let you search in Gallery for more than one person or subject.

Remaster feature works with artificial intelligence to upscale the images captured by your smartphone. The One UI 5.1’s Remaster feature now supports GIF files as well, however, it will now automatically remove shadows and reflections with a better preview.

Galaxy smartphones are well known for their photography skills. In case you use just a single smartphone to capture all your epic moments, sharing with other family members becomes a time-spending task. One UI 5.1 has a solution for this, you can now create a shared family album with 5GB of storage for up to 6 members.

Talking about Multitasking, the One UI 5.1 update for the Galaxy Z Fold 4 and Galaxy Z Flip 4 makes it possible to easily minimize or maximize an app window without going to the options menu. Moreover, mostly used apps can now be accessed even more easily in the split-screen view.

Among others, the new Battery Status Widget feature is also a part of the One UI 5.1 software, copied from Android and iOS. This excellent widget displays the battery status of connected Galaxy Buds, Galaxy Watch, and other supported devices along with the smartphone itself.
