My wife and I both use Samsung Stratospheres. up until a month or so ago, photos/pictures posted on Facebook showed on our phones no problem. We each have a photo posted as our wallpaper. now we are lucky to see one or two during any sessions.
A couple things I considered may effect this but, I am not sure ...
We are both logged in to one account. (Mine, she doesn't have one. Never did.)
Both of us using a posted pic as Wallpaper? Dunno if this matters or not ....
maybe some kind of memory cache needs dumping?
Maybe it is something in my Facebook settings .... I don't know. Hoping someone here can shed some light on this issue.
