While Samsung Galaxy A73 is eligible for the Android 15-based One UI 7 upgrade, it is unknown when the rollout will commence. Samsung still has many things to sort out before the update starts seeding, but you can install the February 2025 security patch as you wait.

The Galaxy A73 February 2025 security patch is available in most Asian countries. It will expand to other regions in the coming weeks. We recommend installing the update when prompted, as it comes bundled with over 40 security vulnerabilities fixes and a fix for the audio output issues in Android Auto.
Aside from improving security and resolving bugs, the update improves performance while fortifying the device for a seamless transition to Android 15 with One UI 7. You can wait for a prompt notification or check manually for it.
