Update brings some Samsung Galaxy S5 features to the T-Mobile Samsung Galaxy Note 345
Another update borrowed from the Galaxy S5 is Kids Mode. With a special Kids Store, free and paid apps can be downloaded. To prevent Junior from buying $500 of games in five minutes, parents can set up a PIN number that can be used to verify purchases. There is plenty here to keep your average pre-teen entertained for hours.
T-Mobile's web site has no changelist for the update, but if you do receive notification that it has arrived on your phone, your best bet is to download it while connected to a Wi-Fi network. And make sure that your batteries are at least 50% charged.
Thanks for the tip, Marco!
