I just received the HTC One X from AT&T. How can I select multiple photos in the Gallery?
My experience of the One X in order to be able to select multiple items in the gallery you need to first give it a task to do.
As far as I can see from playing on my device for 10 minutes, there isn't a general 'multi-select' feature. You might try a different gallery app though. I would recommend QuickPic
