Google announced the Android 11 back in February with the first developer preview that was released on Pixel devices. The Android 11 beta program was kickstarted in June 2020 when it arrived on all Pixel devices including 13 smartphones from 7 vendors. Android 11 was officially launch probably in early September and that is when OEMs will get the update as per their priority list that involves a number of factors.

Talking about Android 11 rollout, it usually takes time for OEMs to tweak it based on their custom skins. The tiresome process is releasing beta and stable updates to eligible phones. When it comes to carrier-branded phones, it takes a step ahead as the carriers to conduct internal testing before releasing the update. This causes delay and it could be on a magnitude of a month from the date of release on unlocked variants of the same phone.
We already have a dedicated list of trackers on Sprint, Verizon, and T-Mobile and here’s a tracker on AT&T Android 11 supported devices that will start its rollout once Android 11 releases in September.
