I found the only way to get it to work is to use syncmypix and then set your default image on your contact to be the google account image. Also make sure that you dont have any contacts on your sim card. I had some and for some reason gosms would use them as the default contact image.
No idea why it has this issue but i assume some permission issue.
I don't understand big companies who put out a product missing such basic features. What this tells me is not a single moronic beta tester / programmer said "Hmm, we should include an option toggle for the screen being turned on when a text message is received."
This feature IMO does nothing but drain the battery. I like the feature, but I would have liked it even more with a setting toggle so I can choose when to turn it on.
