One of 2024's best-selling budget phones: Popular smartphone gets Android 17 update

Based on the Android 17 operating system, One UI 9 is now available for more Galaxy phones. The Galaxy A15, one of the budget-friendly models the company released in 2024, received the One UI 9 update globally. The update previously covered models in South Korea.
First released in the company's home country of South Korea on November 4, 2026, the software brings new customization tools, privacy controls, and accessibility improvements to the device.
Galaxy A15 receives One UI 9 globally
The rollout, confirmed by SamMobile, initially covers the South Korean version with model number SM-A155N.

What is the status for international models?
As of November 9, 2026, Samsung has not officially announced when the update will reach Galaxy A15 4G variants outside South Korea. The official update history of the SM-A155F model, widely sold in global markets, still shows Android 16.
On the Galaxy A15 5G side, the 5G-supported version of the device, the rollout is at a more advanced stage. The stable One UI 9 release was made available for this model in India and the United States. However, because the firmware for the 4G and 5G models has different codebases, the 5G version's schedule does not directly apply to the 4G model.
How to check for One UI 9 on the Galaxy A15
Before checking for the update, users need to verify whether the device is 4G or 5G. Although both models feature a similar design, they run different software. The device type can be checked from the "About phone" menu in the Settings app. While the South Korean 4G model carries the SM-A155N code, the international 4G version is listed as SM-A155F. The 5G models are designated with the codes SM-A156E and SM-A156U.
