Samsung’s Android 16 QPR2-based One UI 8.5 started rolling out in beta earlier this month. Currently limited to the Galaxy S25 series, the new beta is also limited to a few countries only.
We expect One UI 8.5 to be rolled out in stable with the release of the Galaxy S26 series next year, with it subsequently making its way to older Samsung devices. Although Samsung hasn’t offered a concrete (or rough) timeline for when that might happen, the sheer number of internal test builds appearing on Samsung’s servers (via SammyGuru) suggests that the South Korean tech giant might be planning to expedite the rollout.
Samsung has started internal One UI 8.5 testing for the following models:
S series
- Galaxy S26
- Galaxy S26+
- Galaxy S26 Ultra
- Galaxy S25
- Galaxy S25+
- Galaxy S25 Ultra
- Galaxy S25 Edge
- Galaxy S25 FE
- Galaxy S24
- Galaxy S24+
- Galaxy S24 Ultra
- Galaxy S24 FE
- Galaxy S23
- Galaxy S23+
- Galaxy S23 Ultra
- Galaxy S23 FE
- Galaxy S22
- Galaxy S22+
- Galaxy S22 Ultra
A series
- Galaxy A57
- Galaxy A56
- Galaxy A55
- Galaxy A54
- Galaxy A53
- Galaxy A37
- Galaxy A36
- Galaxy A35
- Galaxy A33
- Galaxy A26
- Galaxy A25
- Galaxy A17 LTE/5G
- Galaxy A16 5G
Z series
- Galaxy Z Fold 7
- Galaxy Z Flip 7
- Galaxy Z Flip 7 FE
- Galaxy Z Fold 6
- Galaxy Z Flip 6
- Galaxy Z Fold 5
- Galaxy Z Flip 5
Tablets
- Galaxy Tab S10+
- Galaxy Tab S10 Ultra
- Galaxy Tab S10 FE
- Galaxy Tab S9
- Galaxy Tab S9+
- Galaxy Tab S9 Ultra
It’s worth noting that M and F series devices are currently missing from the test servers, but they will likely make their way over soon, considering almost all devices that got One UI 8 will get One UI 8.5 as well.
If you’re in a hurry to try out the new beta, and don’t own the Galaxy S25 series, your best bet is to wait until early 2026. If you do own a S25 series device, you can easily hop on the beta through the Samsung Members app if you’re in South Korea, Germany, Poland, India, the US, and the UK.
