Just bought the Vivid and I am noticing that I cannot stop the duplication of notifications. I am using the latest version of FB and a setting to stop notifications is nowhere to be found as in prior versions. Ultimately, I would like to have notifications sent to my gmail and not FB. I have always done it this way and I am happy with this setup. If this is not possible, I would entertain getting just FB and not Gmail. The problem here is that I see no place to set a notification setting in FB or on the device. On the device, I see a setting for alarm and notifications only. It seems the new FB version for Android mirrors the desktop version closely.
