There are plenty of updates making the rounds today from Verizon and AT&T. From the RAZR HD, Kyocera Torque, and now the Galaxy S4. We’ve just learned that both AT&T and Verizon have issued software updates for the top dog Samsung Galaxy S4 smartphone. They are rolling out as we speak, and we have all the details below.

Verizon’s update oddly enough isn’t available over the air, as usual, but could arrive that way later this week. For now we’ve learned that Verizon’s PC and MAC desktop installer has the update reading and waiting. However, those on AT&T can update over the air as usual to receive the latest and greatest.

For Verizon users it’s called Software Upgrade Assistant and you can get it by following along these instructions. The update comes in around 350 MB for Both Verizon and AT&T. The update adds support for KNOX suite, and even includes the option to move apps to the SD card. This should help free up some space on those Galaxy S4 devices that are running low. Considering out of 16GB only 8 or so is usable out of the box. We’re also hearing new camera firmware is included with HDR video, and a transparent status bar.

So far we have no changelog from AT&T or Verizon. The updates are quite large and could also have the latest security patches from Google we’ve been talking about lately. On a bit of bad news for enthusiasts. This update will break root access, and no rootkeeper app will save it. It appears Samsung has also swapped out the bootloader for both Verizon and AT&T. This means you won’t be able to use any previous exploits to unlock, or gain root access.

If you’re planning on rooting your Galaxy S4 and running some CyanogenMod or other ROMs, this update will cause you some problems and stop you from achieving that goal. We should have more details soon, and feel free to drop us a comment if you accept the update and notice anything new.
