Galaxy S23 Android 15 test firmware go live on Samsung servers

Samsung may finally have started development on the Android 15 firmware for the Galaxy S23 series (via Tarun Vats). The Galaxy S23 series is expected to be among the first batch of devices that get the One UI 7.0 beta program later this year, but for some reason Android 15 testing for the 2023 flagship lineup hadn't yet begun in earnest.

Okay, that's not entirely accurate. A Galaxy S23 Ultra was benchmarked running Android 15 as early as July this year, so Samsung has been working on the One UI 7 update for the Galaxy S23 series (and other devices) for a long time. However, Galaxy S23 test builds have only gone live on Samsung's firmware servers this month.

We have seen Android 15 firmware for several Galaxy smartphones on Samsung's servers in recent weeks. It's all leading up to what we are eagerly waiting for: the One UI 7.0 beta program. Galaxy S24, S24+, and S24 Ultra owners will get to test One UI 7.0 before everyone else, followed by those who own devices like the Galaxy S23, S23+, S23 Ultra, and Galaxy Z Fold 6.

Samsung will release the official Android 15/One UI 7 update in 2025, following the launch of the Galaxy S25 lineup.
