On my second Droid 2 (not the global version) From time to time I will send a text and the person on the receiving end tells me the text came through blank or with upside down question marks or other odd symbols. It happens with different people and different times. Verizon says it's not a known issue and want to send me "certified like new" replacements, but this is the second new Droid I've had and both have done the same thing. Suggestions?
