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.

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.

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.

Samsung Galaxy S24 FE 5G starts receiving a new One UI 7-based update with the June 2025 security patch. The firmware is rolling out to limited smartphone users in the home market, South Korea. Although the company may soon initiate a broader software release.

The One UI 7 June 2025 security patch fixes a dozen vulnerabilities. It targets bugs hidden in the device system and ensures that private data remains secure. The firmware also fixes flaws that could allow malware to enter the phone.

On the other hand, it enhances the smartphone’s ability to fight problems. After installing the latest June 2025 update on Samsung Galaxy S24 FE, users can find performance improvements and some new add-ons in the device.

According to the changelog, the Galaxy S24 FE is getting the June 2025 update with the One UI 7 S721NKSS4BYE1 version. It carries a software package of 400 MB. The update brings 36 Android CVEs and 19 One UI SVE items to safeguard Galaxy devices.

The upcoming release is rolling out in the Korean market and will reach more regions soon. In the meantime, you can check the Updates section of your device to perform a manual installation. Before proceeding, make sure you have a stable Wi-Fi connection as well as adequate storage and battery levels on your device.

The Galaxy S24 FE smartphone was released with Android 14-based One UI 6.1. Subsequently, the company released the Android 15-based One UI 7 available as the first major upgrade, and now it is eligible to leave the beta program and move to the stable One UI 8 version.

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.
