Latest Galaxy S25 Ultra leak confirms hardware details

Samsung’s next Galaxy Unpackaged The event is expected to take place in late January, which means we’re probably less than a month away from meeting Galaxy S25 series. While we’ve heard a lot about what we can expect, the focus over the past few weeks will be on finalizing the remaining details. Today we’ve crawled through some leaked Galaxy S25 Ultra documents to see what they can tell us about the phone, confirming things like support for Seamless A/B updates. We’ve been looking around and discovered some other important details about how the phone will come to market.

The last thing you want to do with a new smartphone is lose it (well, either lose it or break it), so you might be curious what kind of support the Galaxy S25 Ultra might have to help keep an eye on it. Unfortunately, we see the hardware statement ro.bluetooth.finder.supported=falsewhich indicates that the phone does not support Find my device when it’s turned offjust like the Pixel 9 can do.

Here are the fingerprints identifying the software running on the S25 Ultra from its prop file:

ro.bootimage.build.fingerprint: [samsung/pa3qxxx/pa3q:15/AP3A.240905.015.A2/S938BXXU0AXKG:user/release-keys]

ro.build.fingerprint: [samsung/pa3qxins/pa3q:15/AP3A.240905.015.A2/S938BXXU0AXKG_OXM0AXKG:user/release-keys]

As the Ultra version of the S25 series, you’d only expect the phone to have a big, beautiful screen, and the documents here reveal that the phone has the same 3120×1440 resolution as the previous S24 Ultra. While that hasn’t changed, it sounds like the S25 Ultra can at least increase the maximum brightness slightly, topping out at 3,000 lux in high-brightness mode.

We also saw evidence of a 5,000mAh battery in the Galaxy S25 Ultra. That’s not surprising, as that’s also the same capacity we got on the S24 Ultra, and existing rumors and regulatory filings already suggest it won’t change. It would be nice if confirming storage details was as simple as the battery, and while we can’t answer all of those questions right now, these profiles do suggest that the S25 Ultra will get high-speed UFS 4.0 storage.

A lot of this just adds support for details we’ve mentioned before, or ones that we didn’t expect to change too much, but are still valuable as we continue to take a full look at the Samsung Galaxy S25 hardware data.
