I've had issues just recently with my s3 where I get an email and I dl the pictures or video it shows that it has been dl bit I cannot find the file. It did not go into the dl or attachment file... And when I try to dl it again it says that the file already exists, but where is it?

I have also had someone send me pictures via text and it shows at the top I get them but when I check text messages it's not there.

I don't know why it says that the files are there when I can't access the or find them.

I've tried restarting my phone, pulling out my sd card, checking my memory levels, settings, I can't find anything wrong. I'm either blind or something but it's obviously not working properly.
