Mine Freezes Regularly
I upgraded from the droid x to the razr. I was tired of all the issues that I had with the X and had been through 3 of them.
So I went to the Razr. Now I have the same issues as you apparently, except mine freezes on a regular basis. It will freeze while doing anything. It doesn't matter if you are running apps, listening to music, watching a movie, etc... I went to the Verizon Store to have someone look at it and the Manager said she had not heard anything about them freezing. So I showed her. It took about (no lie) 30 seconds for it to freeze up in front of her.
Long story short, I am now on my second Droid Razr..
If anyone else knows why this may be happening, or how to prevent it, let me know!!
BUT BY ALL MEANS, if it happens to you report it like I did, to Motorola, so they can figure it out. If it happens to enough of us, they may fix it. After all, its a $600+ phone, and should preform like a $600 phone.
