Android 15 might mandate UI rendering with Vulkan instead of OpenGL like on Google Pixel phones

Android’s UI is about to get a major graphics overhaul, potentially leaving some phone manufacturers scrambling. According to Android expert Mishaal Rahman, new code changes suggest that Android 15 might mandate UI rendering using the Vulkan Graphics API, effectively ditching the older OpenGL standard.

While this sounds like a technical jargon dance, it boils down to one thing: smoother, more efficient graphics on your phone. Vulkan offers significant performance benefits compared to OpenGL, potentially leading to faster app launches, reduced battery drain, and even smoother animations.

The move isn’t entirely unexpected. The current Android 14 Compatibility Definition Document “strongly recommends” using Vulkan for UI rendering, and Google Pixel devices have been utilizing it since Android 10. However, the mandatory language in the code suggests Google is tired of waiting for some manufacturers to catch up. This change likely indicates that some OEMs haven’t implemented Vulkan-based UI rendering yet. Looking at January 2023 data, over 80% of Android devices support OpenGL 3.2 while over 85% support Vulkan.

While Google Pixel and the recently released Galaxy S24 Ultra already boast Vulkan-powered UI, it’s possible that some popular brands are still using the old OpenGL standard. With this development, these manufacturers will now have no choice but to adapt and ensure their devices meet the new Android 15 requirement. Of course, the transition won’t be without challenges. Implementing Vulkan requires additional development resources and testing, potentially delaying updates for some devices. However, the long-term benefits for both users and the Android ecosystem are likely worth the initial hurdle.

The news comes amidst other exciting developments in the Android 15 pipeline, including native support for app archiving and a revamped lock screen. With Vulkan joining the mix, Android 15 could be a significant leap forward in terms of both performance and user experience. But the question that remains is will all phone makers be ready to take the leap? Only time will tell.
