Owners of the Sprint’s HTC Evo 4G LTE should had already received a new OTA update from Sprint earlier today. Even though the update isn’t what many have been long for ( the Jelly Bean update ), but it does fixes several painful bugs on your firmware. If you want to view the complete changelog for the update, you can find it here.
However if you have yet to receive the OTA update on your device, you can go to Settings > About phone > System software updates to manually check for the update just in case you’ve been missed out. So is there any noticeable change on the Evo 4G after the update?
