Samsung has reportedly started testing a new version of its One UI software for the upcoming Galaxy S26 series, which could be One UI 8.5. The first news has recently surfaced online, showing that Samsung is working on the software for its next flagship Galaxy S series phones.

A reliable tipster has claimed that Samsung has started working on One UI 8.5 for next year’s Galaxy S series phones. This means the upcoming Galaxy S26, Galaxy S26 Plus, and Galaxy S26 Ultra could launch with One UI 8.5 software.

However, Samsung has not officially confirmed the release of One UI 8.5 yet, so we should take this information with a pinch of salt. Still, it’s clear that the Galaxy S26 series will feature a new version of One UI.

We’ll have to wait for more updates from Samsung to know when these devices will launch and what exact version of One UI they’ll run. Stay tuned for more details.

One UI 8 software update

Samsung fans are excited about the next big software update for Galaxy devices. The One UI 8 Beta has officially launched, with Samsung confirming the program and releasing the first beta update. Additionally, with the beta 2 rollout, Samsung’s One UI 8 beta is now available in Germany, India, Poland, South Korea, the UK, and the US.

Additionally, the stable version of One UI 8 is expected to launch this summer, starting with the Galaxy Z Fold 7 and Z Flip 7, with a rollout to other devices soon after.

Galaxy S25 series owners have joined the One UI 8 beta program. Samsung rolled out One UI 8 beta 1 in four countries last week. Now, Samsung’s beta participants are enjoying the use of One UI 8 beta 2.  Samsung’s One UI 8 beta 2 also packs things that the brand hasn’t mentioned in the changelog, one of them is Real-Time Text.

According to @MKarakachanov,  One UI 8 Beta 2 for the Galaxy S25 brings a feature called Real Time Text, and is an accessibility feature located in Phone Settings. 

As per the information, One UI 8 Beta 2 Real-Time Text (RTT) allows you to have a text conversation during a voice call. RTT is often used to communicate with people who are hearing or speech impaired.

Plus, the other person can see every letter you type in real time. You can erase and make changes, but the other person will be able to see what you changed. Additionally, RTT calls have audio as well as text. If you don’t want the other person to hear you, you can mute the microphone during an RTT call.

To use RTT, you need to be connected to a 4G or 5G network or use Wi-Fi calling. Moreover, RTT calls cost the same as normal voice calls.

Samsung launched the One UI 8 beta program for the Galaxy S25 series in the last week of May. The beta slots filled up soon after, with Samsung promising to accept more users and expand the beta program availability to more regions soon. About two weeks after the first beta, Samsung is launching the One UI 8 beta 2 for the Galaxy S25, Galaxy S25 Plus, and Galaxy S25 Ultra with bug fixes and several other changes. The beta program is now available in more countries as well.

The ZYF3 One UI 8 beta 2 firmware weighs around 1.2GB and packs the June 2025 security patch. 

One UI 8 Beta 2 is available for the Galaxy S25 series in India and Poland as well as all the original regions. Samsung has opened more slots for registration, so if you couldn’t join the first beta program, try your luck now. You can tap on the One UI 8 beta banner in the Samsung Members app to join the program. Hurry up, as Samsung has released limited slots this time too.

Users in Korea, Germany, the US, and the UK can download the latest beta update if they have participated in the One UI 8 beta program. To install the firmware, open Settings >> Software update >> Download and install.
