My 7250 had been recording the occasional call that I didn't remember making. Then this morning it was sitting on the table in front of me and made a call all by itself to a friend sitting at the same table. Noone had touched it.

Does anyone have any theories about how this could have happened?

I don't know why or how it happens, but my 7250 has also done it on occasion.

Mine won't necessarily call someone, but it will call things like "##", or some other weird combination.

Also, sometimes when I call someone, their number appears twice in my call log...

Try keyboard lock sometime.
