Having been an Android user for many years one of the great frustrations that I had was waiting for updates. While Nexus users might be able to install the latest and greatest OS updates, everyone else had to wait for both carrier and OEM approval. In some cases this was quick, but most of the time it took could literally take months. The delay was caused by the specific firmware required for each model, but also that each carrier had to test the latest software before issuing it. In this context Apple have it spot on, as their updates are issued directly. Microsoft has revealed that it will now also take this latter path with Windows 10 Mobile. Having successfully used some technical wizardry to divorce the ‘radio stack’, the phone bit essentially, from the rest of the OS. This means that it will be able to send updates directly to the handset without a requirement for carrier approval, and so it should mean quicker and more regular updates.
