Android phones, apps and tablets

^^ It was a contract free handset but I wasn't pushing for a Kia's update it was a OTA. Some immediate differences in the theme and layout but haven't had time to delve too deeply yet

Hmm, mine was ota, and also a BTU basic UK one, not carrier specific. After getting 4.3 mine stopped coming out of deep sleep, would usually require a battery pull to sort it and music playback was atrocious, amongst other issues. Dog slow too... Be interested to hear how you get on, as I definitely wasn't the only one to have the above issues when it first came out.
