Sprint upgraded its Galaxy S III and Galaxy Note II Android smartphones today with a pair of maintenance updates. The new L710VPMA6 software update for the Galaxy S3 updates the voicemail app, includes support for 3-digit SMS and fixes calendar sync issues. The L900VPAMA7 update for the Galaxy Note 2 simply applies security updates. If you own either device on the Now Network, look for an automatic OTA update notifiation in the coming week or try to manually trigger it through the settings menu.
