Samsung is testing One UI 8.5 on these Galaxy devices

The public One UI 8.5 beta testing began earlier this month, and so far, it has remained exclusive to the Galaxy S25 series. However, the brand is internally testing the latest One UI build on multiple Galaxy devices, suggesting quicker rollout, at least for these devices.

Samsung is testing One UI 8.5 internally on many Galaxy smartphones, and that’s not limited to premium lineups. Several Galaxy A-series phones are also under testing. Here’s the complete list:

• Galaxy S25 Edge
• Galaxy S25 FE
• Galaxy S24, S24+, S24 Ultra
• Galaxy S24 FE
• Galaxy S23, S23+, S23 Ultra
• Galaxy S23 FE
• Galaxy A56
• Galaxy A55
• Galaxy A36
• Galaxy A17
• Galaxy A17 5G
• Galaxy A16 5G
• Galaxy Z Fold 7, Z Flip 7
• Galaxy Z Fold 6, Z Flip 6 
• Galaxy Z Fold 5, Z Flip 5

While internal testing may expand to more Galaxy devices, the public One UI 8.5 beta program is likely to remain exclusive to the Galaxy S25 series. The remaining Galaxy devices eligible for this upgrade may receive the stable update directly sometime next year.

Since One UI 8.5 testing is already underway for these Galaxy devices, Samsung shouldn’t take long to release the stable update to these devices once the rollout begins.

The stable version of One UI 8.5 will debut with the Galaxy S26 series early next year, and then the rollout will begin for older Galaxy devices. The Galaxy S25 series will be the first phones to receive the stable update to One UI 8.5. The rollout will then expand to recent Galaxy S and Z series phones, followed by the affordable phones.
