Do the Galaxy Z Fold 6 and Z Flip 6 support seamless updates?

Samsung announced the Galaxy Z Fold 6 and Galaxy Z Flip 6 on July 10. Using Android developer tools, we discovered that the new foldables do not support seamless updates.

It’s been nearly a decade since Google introduced seamless updating to Android and its Pixel phones. In 2024, Samsung finally brought the feature to one of its devices.

Surprisingly, it was the Galaxy A55, and the A-series phone remained the only one on the market to benefit from seamless updates for months. And it looks like that won’t change with the Z Fold 6 and Z Flip 6.

What are seamless updates and how do they work?

Phones that support the seamless update feature have two system/boot partitions. While they install new updates on one partition, you can continue to use your phone on the other partition without any interruption.

Regular (non-seamless) updates require the user to restart their phone and wait for the update to complete. This will leave them unable to use their phone for several minutes, even for emergency calls.

Seamless updates allow new firmware to be installed in the background without interrupting the user. Once new firmware is applied in this way, users only need to reboot their phones once and don’t have to wait for long progress bars.

The story continues after the video…

Depending on how often you install updates on your phones, seamless updates may or may not seem like an important feature. Still, it’s a quality improvement, especially for devices that get monthly security updates, which is the case with most new mid-range and high-end Galaxy smartphones.

Fold 6 and Flip 6 do not appear to support seamless updates

Unfortunately, the Z Fold 6 and Z Flip 6 don’t support seamless updates, at least not based on our initial testing.However, the methods for testing whether seamless updates are supported are apparently not very reliable. The only way to know for sure is when the new foldables get their first software update.

The Galaxy A55, which supports seamless updates, shows a split progress bar as an update is being downloaded and installed. Devices that don’t support it, on the other hand, have a single progress bar. You can compare the two in the image below – the one on the left is seamless, the one on the right is traditional.

If the Fold 6 and Flip 6 don’t support seamless updates out of the box, that won’t change later. This system of installing updates requires two system partitions, and adding support to a phone that doesn’t support seamless updates requires repartitioning the existing system partition, which can introduce a whole host of problems that Samsung simply isn’t willing to risk.

Seven years of Fold 6 and Flip 6 updates will likely be installed the old-fashioned way

Samsung may have skipped seamless updates for its new flagships because the software running on its flagship Galaxy smartphones and tablets typically takes up a lot of space (almost twice as much) compared to mid-range and budget devices.

For example, the Galaxy A55’s full firmware is around 8GB in size, while the Galaxy Z Fold 5 and Galaxy S24 Ultra’s firmware download sizes are around 14GB and 16GB, respectively.

Still, it’s a little disappointing that the Fold 6 and Flip 6 are eligible for seven years of OS and security upgrades, since all of those upgrades are installed the old-fashioned way.

Galaxy Z Fold 6 and Z Flip 6 go on sale from July 24

The new foldable phones come with Android 14 and One UI 6.1. 1, along with new Galaxy AI features. They go on sale on July 24, but you can earn bonuses if you pre-order early.
