Force an Android Device to Check for a System Update
Android: If you know or suspect there's an update available for your Android device but nothing's showing up when you check for a system update in the device settings, here's an alternate method to force a check right now.
Usually you can go to Settings > About Phone > System Update to check for available updates, but the problem with that is carriers often have staggered release cycles.
Ghacks posts an alternative method. Go to Settings > Apps (or Applications) and select show All. Then find Google Services Framework and click the Clear Data button. Then click the Force Stop button.
Note that this might not work on the first try.
Another alternative method, which we've mentioned before, is to dial*#*#checkin#*#*(using the numbers on the dial pad for the letters). Clearing and forcing Google Services Framework to close is easier to remember, but the checkin code may be quicker.
Either method could help you get your bux fix or big version upgrade faster. Note, however, that if there's no update available, it won't magically create one for your device.
