My camera on my iPhone quit working. By doing a google search I found this product from Tenorshare. It said they had a money back guarantee so I thought I had nothing to lose. I ran the software and it did not fix the camera. I emailed and requested a refund, sent in the logs as they requested and am still being denied a refund. I have turned in the phone on and insurance claim and got it replaced. Here is their guarantee: Any technical problems you have encountered when using the product, please contact Tenorshare's technical support team and cooperate to locate the problem, including providing screenshots and log files, or accepting free remote services provided by Tenorshare. If the problem cannot be resolved in the end, and you are unwilling to wait for an upgrade or other compensation plan, Tenorshare will refund you if your order is in 30 days.
