One UI 8.5 Arrives on Budget Galaxy Phones: Full Rollout, Features & What Owners Need to Know

Samsung’s stable One UI 8.5 update, based on Android 16 QPR2, has accelerated its rollout, rapidly moving from flagship Galaxy S25 devices to budget and mid-range models. As of late May 2026, owners of the Galaxy M55, Galaxy A16 5G, and Galaxy A17 5G began seeing the update hit their devices.

Here’s a breakdown of exactly what’s arriving, on which devices, and what it means for older Galaxy phones.

Latest Budget Devices Receiving One UI 8.5

The rollout to affordable A-series and M-series phones marks an unusually fast update cycle for Samsung, bringing a mid-cycle feature release to entry-level devices just weeks after the flagship launch .

• Galaxy A17 5G: The stable update went live on May 29, 2026, in multiple countries including India, Bulgaria, France, Nepal, and Vietnam. It arrives with firmware version A176BXXU5CZE9 and a download size of approximately 2.4GB, including the May 2026 security patch .
• Galaxy A16 5G: Rollout began shortly before the A17, alongside the Galaxy A26. Samsung's official support page for Hong Kong lists the A16 5G with a scheduled rollout in June 2026, indicating a phased deployment .
• Galaxy M55: Owners in India began receiving the update with firmware version M556BXXU5DZE3. The package is about 3 GB in size and also includes the May 2026 security patch .

To check if the update is available on your device, navigate to Settings > Software update > Download and install. If you don't see it yet, don’t worry — Samsung is aiming to complete the full rollout by the end of June 2026 .

What’s New: Features and Security

One UI 8.5 introduces a range of visual, functional, and security improvements that go beyond a standard Android security release .

Refreshed Visual Design
The UI has been updated with more transparency and prominent blur effects throughout the system, creating a layered, modern look .

Fully Customizable Quick Panel
This is the headline feature: every toggle and slider in the Quick Settings panel can now be rearranged, resized, or removed entirely. Samsung has also refreshed the interface for adding new controls .

Enhanced Lock Screen
The lock screen gets several upgrades. New clock font options have been added, and the layout can now automatically adjust based on the wallpaper. Better subject detection — for pets, people, or scenery — allows the clock UI to reposition itself behind prominent elements without manual tweaking .

Security and Privacy

• Theft Protection: A new suite of anti-theft measures comes built-in, including an auto-lock feature that kicks in after too many failed biometric or PIN authentication attempts .
• Auto Blocker Toggle: Users can now temporarily disable Samsung’s Auto Blocker feature, which prevents sideloading and unauthorized app installations .
• Additional Safeguards: Hidden OTPs on the lock screen, active scanning for malicious app icon changes, and built-in app locking (no third-party app required) are all part of the new package .

Quality-of-Life Improvements
Other additions include partial screen recording (allowing you to capture just a portion of the display) and an improved power-saving mode .

What the Update Means for Older Galaxy Phones

Samsung’s update policy is coming into sharp focus with the One UI 8.5 release, as it represents a final chapter for several popular models.

Galaxy S22 Series: The Final Major Update

The Galaxy S22, S22+, and S22 Ultra are confirmed to receive One UI 8.5. However, Samsung has designated this as the final major OS update for the 2022 flagship lineup . The S22 launched with Android 12 and has fulfilled Samsung’s four-generation upgrade promise with updates to Android 13, 14, 15 (One UI 7), and 16 (One UI 8). After One UI 8.5 installs, these devices will enter a maintenance-only phase, receiving quarterly security patches until approximately February 2027 . Samsung also recently pushed a separate May 2026 security patch (around 506MB) to the S22 series, fixing 36 vulnerabilities .

Galaxy S21 FE: Unclear Eligibility

If you own a Galaxy S21 FE, your update status remains uncertain. Samsung has not issued an official statement confirming or denying One UI 8.5 eligibility for the device. While the S21 FE continues to receive security patches (through at least January 2027 under Samsung's 4-year security commitment), it was launched in early 2022 and falls outside the company’s typical focus for 2023-and-later devices . Some outlets have listed the S21 FE as a candidate for One UI 8.5 being its last major update, but unlike the S22 series, no definitive confirmation from Samsung has been published .

Global Rollout Timeline

Samsung’s deployment has been moving fast since the stable branch first launched . Here’s how it unfolded:

• May 6, 2026: Stable rollout begins in South Korea, starting with the Galaxy S25 series, Galaxy Z Fold7, and Z Flip7 .
• May 11, 2026: Global release kicks off, covering Europe, India, North America, Latin America, Southeast Asia, Hong Kong, and Taiwan .
• Mid-to-Late May 2026: Rapid expansion to over 40 devices across the S, Z, A, M, and Tab lineups. Mid-range and budget devices like the Galaxy A16/A17, Galaxy A36/A56, and Galaxy M55/M56 are in this wave .
• End of June 2026 (Target): Samsung’s stated goal is to complete the One UI 8.5 rollout to all eligible devices by the end of June .

If your device is on the confirmed list but hasn’t notified you yet, the update is likely still propagating across your region’s carriers and unlocked models. The next few weeks will complete the picture for most Galaxy users globally.
