Samsung has begun internal testing of One UI 9 for the Galaxy A37, and the first firmware build has already surfaced on the company’s test servers. The move matters because it shows Samsung is pushing its next Android 17-based software beyond premium phones and into the crowded midrange, where update support is becoming a bigger selling point by the month.
The build spotted for the Galaxy A37 is A376BXXU3BZG1/A376BOXM3BZG1/A376BXXU3BZG1. One UI 9 is Samsung’s software layer built on Android 17, and the A37 now joins a long list of A-series devices already linked to the same work, including the Galaxy A57, A56, A55, A54, A35, A34, A25, A24, A17, A16, and A07.
Galaxy A37 joins Samsung’s One UI 9 testing
Samsung has been testing the new software internally for several weeks, mainly on high-end and midrange models. What’s more interesting is that budget phones have now started showing up on the test server too, which suggests the company is moving faster than it usually advertises. That is classic Samsung: broad support in theory, but only after the engineering work is already quietly underway.
The Galaxy A line is doing a lot of heavy lifting here. Samsung’s A-series dominates the company’s sales mix in many markets, so bringing major Android upgrades to this tier is not charity – it is table stakes if Samsung wants to keep buyers from drifting to rivals that now pitch software longevity almost as aggressively as hardware.
How the firmware leak was found
The firmware was spotted on Samsung’s servers by Tarun Vats, a leaker with a decent recent track record. He previously pointed to an earlier-than-expected One UI 8.0 beta and also surfaced release timing for the Galaxy S24 and Galaxy S25, along with repeated accurate calls around One UI 8.5. In other words, this is the kind of breadcrumb that tends to turn into a real rollout later.
- Software: One UI 9
- Base system: Android 17
- Device spotted: Galaxy A37
- Detected build: A376BXXU3BZG1/A376BOXM3BZG1/A376BXXU3BZG1
What to watch next
For now, this is only internal testing, not a public beta or a launch schedule. The more useful signal is that Samsung is already preparing One UI 9 for a device in the Galaxy A family that sits far below the flagship spotlight, which usually means the wider rollout plan is taking shape behind the scenes.
The open question is how quickly Samsung will move from quiet server builds to something users can actually install. Given how aggressively competitors are marketing update promises, Samsung has every reason to keep the pace up – especially on phones that win or lose customers on software, not spec sheets.
