5G is the fifth generation of wireless technology for mobile networks, offering faster data transfer speeds, lower latency, and greater network capacity compared to previous generations
Evidently, 5G is not working in most countries in the world (by Pixel 6), and slowly in Google Android updates they enabled it in more countries.
Kaymera OS is built on an older version of A12 and therefore even if Google will release a version that enables 5G on Pixel 6 in a specific country, it will still not work in the Kaymera A12 version.
We are now working on A13 which will be more dynamic and will include Android updates as well.
