The update fixed the issue I was having with both wifi and bluetooth on (only) in my home.
I could not access the internet using wifi 2.4 band, unless I turned bluetooth off.
Wifi seems a lot faster for me.
I have the same problem, but it only seems to happen on my home wifi.
It is so slow or won't connect, until I turn off bluetooth and then the page it is trying to display instantly appears.
I have not done a reset.
I am going to Best Buy today to talk to the Samsung rep.
I am so happy, having replaced my galaxy nexus with the moto x. The galaxy nexus would get hung when I responded to 'group text messages', sometimes sending it days or weeks later.
I love my moto x -- no complaints.
I have the clear tpu Rocketfish case from Best Buy and love it. If you have a custom moto x, it shows the colors really well.
The only thing it is missing is a grip material on the sides, but I do like that the sides are clear.
