I am a realtor and use my smart phone for taking property photos to post online. However, I had trouble using it the first time. I could not find all the photos I knew I took, and had to ask my husband to help He ended up trying to recover pictures from sd card units I had in my computer. If worked, too. Somehow I was syncing the device and my laptop wrong and the photos were not showing in the E: or C: drives, as they should. But once my hubby hooked up the sync mode right, it worked fine.
