Has anyone fixed the following droid razr problems: 1. the phone won't let me answer calls, if the answering screen shows up it takes 5 rings; 2.It takes about 4 attempts to end a call, half the time I have to wait for them to hang up; 3. GPS will stop and freeze; 4. phone freezes doing simple tasks; 5. It won't flip through easily; 6. slow (deleted texts and photos and still slow); 7.deleted apps still show on phone; 8. battery life is about 3 hours if used constantly; 9. some people cannot call me; 10. typed text takes a very long time to appear on the phone.
