With Android 15, Google introduced support for 16 KB memory page sizes in the OS. It is expected that device manufacturers will start bringing out devices with these capabilities to the market. Google’s testing suggests that there are noticeable performance gains in apps and games launching on 16 KB-capable devices, with up to a 10% improvement.

Support for 16 KB sizes is now available in the following Unity versions:

- Unity 6000.1.0b5 (expected release: February 9, 2025)
- Unity 6000.0.38f1 (expected release: February 14, 2025)
- Unity 2022.3.56f1 (released: January 15, 2025)
- Unity 2021.3.48f1 (released: January 22, 2025)

All native libraries in your project must be 16 KB compatible. Currently, the page size is 4 KB, and larger pages bring the following benefits:

- Lower app launch times under memory pressure: 3.16% lower on average, with more significant improvements (up to 30%) for some apps tested by Google.
- Theoretically reduced page table overhead: Since there are fewer pages to manage.
- Improved I/O performance: Larger pages require fewer read and write operations for data spanning multiple pages.
- Cache efficiency: Larger pages can lead to better cache usage, reducing the number of cache misses if your app has good data locality.
