From information on this BBS, that's something I did not expect.
Probably my information
I'm afraid my experience of restoring apps and data (including photos) on Android has been patchy at best
I think it might be just that it has gotten a lot better quite recently or something. And it only works if I first allow everything to be backed up to Google, which normally I don't allow.
And I'm not sure about the photos.. I probably copied those manually because (1) they're huge, and (2) I never grant Google permission to steal those.
Cheers!
