the next significant iteration of Android arrives, likely in 2013. Nexus branded devices are some of the only Android phones or handsets to qualify for two significant releases of Android, as opposed to one. How to do I check for updates? If you're sure your device is due an update and you haven't yet received anything or you simply want to check, the process is simple. Head to Settings in your app drawer and press the 'About Phone', 'About Tablet' or ' About Device' section depending what appears and then press the 'Check for updates' option. If you do find an available update for your device, ensure that you have at least 50% battery life or plug it into the mains. Unless you make use of an unlimited data tariff, download the update over a WiFi network. Alternatively, if WiFi OTA (over-the-air) updates don't appear to work or you prefer not to use them, most manufacturers provide computer software (such as Samsung Kies), which can be used for updating via USB. In some specific cases (as with Sony), you have to use software, as there is option to check for updates over the air.
