Sprint is rolling out an update to the Galaxy S5 to fix a bunch of issues that have been plaguing users since the device launched back in the second week of April. The 41MB over-the-air update fixes issues like the camera app not loading when a voice call was active, alarm failure when deleting alarms, duplication of emails when moving them one from folder to another, and two bugs associated with the Google Search app and the S View Cover. Note that this update will probably not be rolling out to the international variant, as it seems to focus on issues found on the Sprint variant.
The update will bump the software version up to G900PVPU1AND2, and as always, will be rolling out to devices in stages. You can force it to show up manually from the Settings » About phone » Software updates menu, though that may or may not work depending on how lucky you are.
