When a new Android Operating System update is announced by Google there are a few steps that take place before it becomes ready for your device. The manufacturer receives the update and customises the software for the device and mobile carriers in each country. Once this is completed they’ll send the update to the carriers for testing.
The below table provides info on the latest Android updates we’ve received for testing and approval as of 04/04/2016. If no info is listed, it means we haven't received the build or any new details from the manufacturer.
When a version is marked as completed it means testing has been finished on our end and approved. Each manufacturer has a process for releasing updates to devices & once we approve the update, it’s sent back to the manufacturer to be released through their standard update processes. Generally, updates are rolled out progressively, where it’s made available for a small number of users (5% for example) initially. If no unforeseen problems pop up, it’ll be gradually made available to more & more users over a period of a couple of weeks.
