I accidentally deleted pictures off my phone and tried to retrieve them with this app. I paid for the download and, in the instructions, it says it is not recommended to "root" if you have a Verizon or AT&T phone. The only way to retrieve deleted pictures is 1. The phone needs to be rooted and 2: lost data hasn't been overwritten by new content. Well, since they do not recommend rooting on a Verizon phone, which I have, I sent an email asking for a refund. I figure if the app developers themselves don't recommend it then they must know what they are talking about. This all transpired on Aug 12th and I am still trying to get a refund. I have been going back and forth with them. First they explained about the root system which I responded to that they themselves recommended not to do on a Verizon phone. Then they asked for the model of my phone to prove it was a verizon phone, which I did. Then i got an email that gave me a link to a site that would help me root the phone. That tutorial was sent 8/26, fourteen days after I sent the original email stating I couldn't use their app. The data had been overwritten by new content by 8/26 because they basically advised I couldn't use their app. I again asked for a refund to which I get a reply saying they offer a free trial and there I would have seen that the rooting step was needed. I wanted my pictures and chose to believe they could supply an app that would help me so I just bought it outright. STAY AWAY, especially if you are a Verizon or AT&T phone user.
