I have run into a little problem. When sharing a photo from the camera roll, adding tags and uploading to Facebook, it subsequently deletes my photo from the camera roll. I notice that the photo successfully uploads to Facebook but has been completely deleted from my phone. When I do this process through the Facebook app, the photo remains on my phone and does not get deleted. Is this a bug with Miui? I have lose some very important photos due to this problem. Any assistance would be appreciated.
