Verizon is rolling out a nice little update (not to Android 4.3) to the Galaxy S4. The build number is VRUDMI1, and the update adds Samsung's Optical Reader application, which allows users to find contacts, addresses, and business cards with “real-time recognition,” and also includes updates to a number of Samsung apps including WatchON, Air View, Samsung Hub, S Health, and more.
In terms of improvements, the update brings better Wi-Fi connectivity, improvements to device wake-up on pressing the power/home button, fixes for force closes on long video recording sessions, ability to roam on TELUS' network in Canada, relocation of driving mode setting to S-Voice settings, and a few other changes. It's not exactly a major update, but it should keep things interesting until the Android 4.3 update arrives later this year.
As usual, the update – which is around 150MB in size – is rolling out over-the-air and might take a while before it reaches every handset. Don't forget to force a check through the Settings » About phone » Software update menu.
