Should smartphone manufacturers be required to provide longer software support for older devices?
Samsung has launched its One UI 9 update, built on Android 17, for Galaxy smartphones. The rollout follows a phased schedule that began in South Korea and has since reached the United States.
Why it matters
The software update introduces new features to current Samsung hardware, though it marks a software milestone for older models that have now reached their support limits.
The One UI 9 update arrives as a 4GB file for the Galaxy S26 Ultra. Older devices like the Galaxy S22 and S21 FE are capped at four major Android updates and will remain on One UI 8.
The players
Samsung
Samsung is a leading global technology company headquartered in South Korea that manufactures consumer electronics, including the Galaxy smartphone series.
T-Mobile
T-Mobile is a major wireless network operator in the United States that facilitates software distribution for mobile devices on its network.
The details
Users can install the software by navigating to Settings and selecting Software update, provided the device is connected to Wi-Fi. The update comes preinstalled on the Z Fold 8, Z Fold 8 Ultra, and Z Flip 8 models.
Timeline
September 16, 2026: The Galaxy S26 update rollout began in South Korea.
September 23, 2026: The Galaxy S26 Ultra update reached T-Mobile US users.
September 30, 2026: Expected completion for Galaxy S25 and Z7 series updates.
End of 2026: Expected rollout for remaining Samsung devices.
The Tech Race
This release reflects the ongoing industry shift toward longer software support windows to extend device longevity. It marks a departure from earlier cycles where hardware replacement was necessitated by software obsolescence more rapidly.
Users can expect improved features and system stability upon upgrading to the Android 17-based software. However, owners of the S22 or S21 FE will not be able to install the update and will remain on their current operating system version.
The takeaway
Users should ensure their devices are charged and connected to a stable Wi-Fi network before attempting the 4GB update installation. Keeping software current is essential for security, though users with older hardware may need to prepare for eventual device transitions as support cycles conclude.
What happens next
The Galaxy S25 series and Z Fold 7 and Z Flip 7 models are scheduled to receive the One UI 9 update by September 30, 2026, with a broader rollout for additional devices expected by the end of 2026.
