How To Force an Update Check on Android Phone

1.Open the Phone app. You can force your phone check for available
updates using dialer. Some people report success using this method to get updates before their device normally would. This method will not create an
update if there is not one available.

2. Dial *#*#2432546#*#* . Your phone will automatically check for updates as soon as you dial the last *.

3 Look for the "checkin succeeded"message. This will appear in your Notifications bar. This indicates that the connection was successful, but does not mean that an update is necessarily available.
