One UI 8 Stable Update Reaches Samsung Galaxy Wide 8 and Galaxy A35

Saturday, 04 October 2025 at 00:19

Samsung has begun pushing the stable version of its Android 16-based One UI 8 to more devices. The rollout is now live for the Galaxy Wide 8 in South Korea. It is also available for the Galaxy A35 in select global markets. This marks another step in the company’s ongoing update campaign.

Update for Galaxy Wide 8

The Galaxy Wide 8 is the latest model in Samsung’s Korean lineup to receive the new software. Users in the region are getting firmware version M166SKSU3BYI8. This brings the full set of One UI 8 features for this device.

While the Wide 8 name is specific to South Korea, the same phone is sold globally under different branding. In most markets, it is known as the Galaxy M16. In some regions, it is offered as the Galaxy F16.

That means the stable One UI 8 should be on its way to M16 and F16 units very soon. As usual, the rollout will be in phases. This means that not all units will get the update at the same time.

Update for Galaxy A35

Samsung is also releasing One UI 8 for the Galaxy A35, one of its mid-range hits of 2024. The update has started rolling out in Iran. It uses the firmware build A356EXXU5CYI8 / A356EOJMCYI8.

Like other One UI releases, availability will expand to additional countries in the coming weeks as Samsung widens the rollout.

By rolling out One UI 8 to both the Galaxy Wide 8 and the Galaxy A35, Samsung is showing its commitment to keeping users updated, no matter the price bracket.

How to Check for the Update

If you have one of these phones, there should be a prompt for you to update your device. If you have not received this prompt, no need to fear. Just follow the steps below

Open Settings on your Samsung phone

Scroll down and tap Software update

Wait while the phone checks for updates

If an update is available, tap download and install

If no update is found, you’ll see a message saying the software is up to date

The last point may mean that you have to wait a bit longer to get the update.

What’s Next

With One UI 8 now making its way to more mid-range phones, Samsung looks set to pick up the pace through October. Owners of the Galaxy M16 and F16 should see the update very soon. This update for the Galaxy A35 should reach more countries beyond Iran in the weeks ahead. For Galaxy users, it means a growing number of devices will soon share the same smooth, Android 16-based software experience.
