Along with Android 12 and its new partnership with Samsung, combined with rumors of a Whitechapel-powered Pixel 6 and Pixel Watch, this is Google's best opportunity to create an Apple-like ecosystem for Android users.
The Android 12 beta isn't just limited to Pixels; the build is making its way to the latest devices from Xiaomi, OnePlus, OPPO, Vivo, Realme, and others. The third-party Android 12 beta counts 11 manufacturers in total, so if you're interested in taking a look at Android 12 and don't have a Pixel, you're in luck.
