Samsung isn’t wasting any time with its One UI 7 release. Following last week’s launch in South Korea, the update is now reaching Galaxy A15 units across multiple continents, including Asia, Europe, and North America. The rapid rollout signals a broader push to bring the latest features and refinements to Galaxy A15 users worldwide.
Galaxy A15 owners can identify the new firmware with the build numbers A155FXXU6CYE3 and A155MUBU6CYE3. The size of the update is close to 3 GB, so it might take a while to download and install it on your device. Also, part of the upgrade is the May 2025 security patch to counter some of the newly found vulnerabilities in the One UI system.
This is a full OS update with Android 15 x One UI 7, and you will find multiple new features and abilities on the Galaxy A15 after you finish installing this software on your device. This is the first major OS update for the Galaxy A15, which leaves you with three more years of support down the line.
One UI 7 is rolling out to the remaining markets in stages, and it should eventually arrive in Pakistan in a matter of days. You should go to Settings, navigate to the Software Updates section on your latest Samsung budget mobile, and tap “Check for Updates” to see if it has been unlocked in the country.
Once you have the update available, you can tap the “Download and Install” button and wait for the device to complete the process, upgrading to One UI 7. The new OS will welcome you to a redesigned UI, more customization features, updated native Samsung Apps, and, best of all, Live Notifications.
The detailed Changelog should have everything you need to know about the new improvements and features that are part of the package, so make sure to read it first. Generally, the One UI 7 update has introduced a split control center, smoother animations, and more readable notifications to eligible devices. The contents of the software vary from device to device.
One UI 7 has yet to be rolled out across several eligible devices, and if you own one of those officially listed models, be sure to stick around to know exactly when you can access this new update. Stay tuned for more news regarding the One UI 7 update.
