Samsung may be planning its biggest software overhaul in years, but it probably won’t arrive soon. A leak from the insider phonefuturist on X says Samsung and Google are working on a new version of Samsung’s phone software, referred to internally as either One UI 10 or Galaxy OS. A report cited by the source suggests it could launch with the Galaxy S28 series in 2028. The project is reportedly at an early stage, and these details come from a leak, not an official announcement.
What you need to know
- The leak says the project is called either One UI 10 or Galaxy OS internally and is being developed with Google, so it would still be based on Android.
- The central idea is AI built into the system itself. One example is finding, editing and sending a photo with a single request.
- The overhaul could arrive with the Galaxy S28 series in 2028 and is reportedly still at an early stage.
- The Galaxy S24 and newer flagships, the Z Fold6 and Z Flip6, and the Galaxy A16, A26, A36 and A56 should still be supported in 2028.

A possible design for Samsung’s Galaxy OS interface
Where the Galaxy OS name comes from
Samsung has called its software One UI for almost eight years. The new rumor comes from a post on X by the insider phonefuturist. According to the leak, Samsung and Google are developing the next version of the software together, and the project is referred to internally as either One UI 10 or Galaxy OS.
The main goal is reportedly to build artificial intelligence into the system itself rather than add it as separate features. One example given is a single request that finds a photo, edits it and sends it to a contact.
Samsung has renamed its software before
One UI is already the third name for Samsung’s own software:
- TouchWiz ran on the first Galaxy smartphones and was widely criticized as cluttered.
- Samsung Experience replaced TouchWiz in 2017.
- One UI arrived in late 2018 with a new design aimed at easier one-handed use.
The source argues that a new name from Samsung has usually signaled a major redesign rather than simple rebranding.
Samsung has also tried building a fully independent platform, Tizen. It powered budget smartphones in the Z series and lasted longest on watches and TVs. In 2021, however, the Galaxy Watch4 switched to Google’s Wear OS. Since then, Samsung has developed its mobile devices alongside Google rather than in place of it.
Based on the leak, Galaxy OS would not be a separate operating system either. Because it is being built with Google, it would still be based on Android.

The overhaul may not come before the Galaxy S28
According to a report cited by the source, the major update could arrive with the Galaxy S28 series, which means 2028. By then, One UI would be almost ten years old. The same report says the project is still at an early stage.

A possible design for the Galaxy S28 Ultra
That timing is later than Samsung’s usual schedule would suggest. According to the source, the interim One UI 9.5 will launch on the Galaxy S27 in early 2027. Under Samsung’s usual pattern, the next major version would have followed in summer 2027. If the leak is accurate, the full overhaul would come about a year later. That makes the key question which phones will still receive updates in 2028.
Which Galaxy phones may get the new software
If the overhaul ships in 2028, only models with long update commitments are likely to receive it. According to the source, these devices will still be supported in 2028:
- the Galaxy S24 series and all newer flagships, which have seven years of Android updates;
- the Galaxy Z Fold6 and Z Flip6 foldables, which also have seven years;
- the Galaxy A16, A26, A36 and A56, which each get six Android updates.
Some popular models will likely stop receiving major updates before then:
- the Galaxy S23, whose last major version is expected to be One UI 9;
- the Galaxy A35 and A55.
What remains uncertain
Everything here comes from a leak and from reporting on it. The source author concludes that Samsung is preparing its biggest software overhaul in years. In the author’s view, however, it will most likely keep the One UI name and should not be expected before 2028.
The author also suggests that buyers who want to be in line for the new software should choose a Galaxy S24 or newer, or an A16 or newer. That advice depends on the leaked 2028 timeline holding.
