It seems like almost every other variant of the S5 has now been updated to 4.4.4. Verizon has actually even updated their 4.4.4 with a newer patch. So, what's the hold up with Sprint? I love locking my phone with the finger print scanner, but it takes several swipes to unlock it most of the time. I understand that's fixed. Bluetooth audio is also barely usable as it's so choppy. I hear that's also been fixed. What's taking them so long to release the update?
