If you're the proud owner of an unlocked HTC One smartphone, you should now have access to an Android 4.3 update. If you picked up a locked device from a US carrier, you're likely out of luck, but global users can now snag the latest version of Jelly Bean. According to Android Highlights, improvements include a battery charging percentage indicator, boosted low-light camera performance, Sense 5 enhancements and increased stability overall. Check the update menu to see if your device is eligible.
