Third-party charger issue purportedly fixed
A small follow-up update to the original jump to Android 4.3 back in October is hitting Verizon Galaxy S4's today with a few small fixes and improvements. According to the Verizon support document for the update, email connectivity has been improved, as has data roaming across Canada and Mexico. Further, data speeds when using enterprise proxy servers have improved, and a notable issue of third-party chargers not charging the phone should be resolved as well.
The new software version after the update will be I545VRUEMK2 — if you've received the update and are noticing any big changes, be sure to hit the forums and let other members know how it's going.
