Hello. I'm new to this forum and discovered it because of the frustration I'm having with my Droid 4. This is actually my 2nd Droid 4. I got this one as a refurbished replacement when my first Droid 4 kept having problems. Not sure this one is much better... Anyway, I had this problem on both phones. If I go to Settings and uncheck vibrate and set phone to silent, it keeps resetting itself. This is embarrassing when I'm in a meeting or just during regular work hours. I keep my phone on in case my kids call and the noise from the vibrate is obnoxious! Is there a way to disable vibrate and make it STAY? And why won't my phone stay silent when I set it up that way? One other annoying feature: the loud beep when the phone hangs up. I haven't been able to find a setting to silence that. Does anyone know how to do that? Maybe the Droid 4 is just defective in this manner. If so, I'll be asking Verizon to replace my phone yet again. Thank you for any help you can give me!
