So I purchased my new HTC One yesterday and setup was surprisingly easy. I began installing some of the apps I had used on my EVO. I got Handcent installed and made sure it was the default SMS/MMS app. I went into the stock message app and basically turned it off, by deselecting all the checks.
Now, since yesterday, any text I receive has come through multiple times, over and over. E.g. I got an email from CNN and through the night, it came through 8 times. I texted a friend yesterday and am still getting the reply, about 15 times so far.
Anyone have any idea what may be causing this??
