I have a Samsung Stratosphere. I'm wanting to disable email notifications during nighttime hours. I have a gmail account, but instead of using the gmail app (with the red M in the icon), I'm using the email app (which came with the phone) that has the green @ symbol. It provides capability for setting peak and off-peak hours where you can "supposedly" change the synch frequency, but it doesn't appear to be working for me. I have the "peak" time set from 8am - 10pm, synching every 5 minutes during that period of time, and only synching manually during the off-peak time period. However, it's still automatically synching (and sending audible notification!) at all hours of the night. Does anyone know how to get this to work properly? Any help would be appreciated. I need to keep the phone by my bed as it's my only phone, but don't want to be constantly woken up by email notifications in the middle of the night. Thanks.
