About 6 months ago, I purchased a new BlackBerry phone. As I used it, I noticed there was an inordinate number of double-typing – in typing “how are you?” it would spell out, “hhhhooww arrre youuu?”
I just assumed it was my poor typing.
Finally I decided to do a quick Google search to see if anyone else had reported the same issue. It turns out that there is a problem with that model phone manufactured during a certain time period that was causing the issue. I then called my carrier, and sure enough, they will exchange the phone (for a slight fee as it is out of warranty).
