Samsung Kicks Off One UI 8 Tests for Galaxy M15
Samsung has officially begun internal testing of Android 16-based One UI 8 for the Galaxy M15, a budget-friendly smartphone in its lineup. The move suggests the company is preparing the groundwork for an earlier-than-expected rollout.
Internal firmware builds have been identified in India, Europe, Brazil, and Mexico, signaling widespread regional testing.

This news comes shortly after One UI 8’s official unveiling on July 9, with Samsung confirming the software would begin rolling out starting July 25 for newer foldables. Older devices, like the Galaxy M15, are slated for gradual updates in the months to follow.
What to Expect from One UI 8 on Galaxy M15
While the Galaxy M15 won’t receive flagship-tier features or AI enhancements, users can still expect notable UI improvements and performance upgrades.
Key expected changes include:
- Redesigned Quick Panel: Now features borders around quick settings for better visual clarity.
- Back Swipe Preview: Offers a preview of the previous screen before fully navigating back—enhancing user control.
- Smarter Reminders: Includes new options for travel-related alerts and categorized reminders, boosting productivity.
- Refined Interface: Overall smoother animations and layout enhancements, streamlining daily use.
Although AI features will be omitted, the update will still deliver a more polished, user-friendly experience for Galaxy M15 owners.
Samsung’s Preparations Behind the Scenes
To ensure a smooth rollout, Samsung is currently updating core system apps and plugins for One UI 8 compatibility. This step ensures all supported features function correctly once the software reaches Galaxy M15 users.
These backend upgrades help avoid post-update glitches, particularly in budget models that rely on optimized system performance for day-to-day reliability.
When Will the Update Arrive?
While there’s no official release date for the Galaxy M15’s One UI 8 rollout, internal testing indicates it could land sooner than expected. That said, it will likely still trail updates for flagship and premium models.
Users can anticipate a Q4 2025 rollout, depending on the results of testing and carrier certifications in each region.
