a few things to report, 1 good, 2 bad.
good: using the same car charger that i used with my S3, this thing charges SUPER FAST. alright!
bad: VOICEMAIL!!!?? what are you guys doing in regards to voicemail? if i get a voicemail, the phone doesn't alert me with an icon, flashing light, etc. i have to manually hold 1 to call myself to see if i have messages. no visual voicemail, this sucks. sprint needs to release their visual voicmail app in the play store with kitkat compatibility!
bad: mightytext. this does not work. maybe needs an update to work with kitkat/hangouts??!?!
