I just noticed this when I just flashed my S2 with the galaxy nexus F1 rom.
A few of my contacts where not on google when I downloaded them to my phone. After investigating I found that any contact I put in my phone that has a number only and no email address will not sync up to google ?.... I tried making different groups and using the default contacts app and Go contacts app, the same
Yes, before anyone asks I did add to the google address book not local
I know it couldn't be my phone settings and must be a google and ICS thing, as it was obviously happening before I went from the samsung 4.03 rom to the nexus F1 rom, and is still happening, it never happened on gingerbread
My wife has a galaxy S on gingerbread and has no problem syncing, she also syncs to the same google account so its not the google account either
So basically WTF ? I don't really want to have to put an email address in every time I add a new number
Is anyone else having this issue ?
