The device fomatted itself three times in a matter of seven days. The SD card reads, detects and uses SOME of the FILES but I can't transfer pictures from phone to SD card for some reason. During the transfer, The picture removes itself from the device and leaves behind a digital trail. And places another gray type file that is not usable on the sd card. This leaves me with no usable files on the device or sd card. I've replaced the sd card three times and the result is the same . The device loses connectivity to wireless and wifi IF I have anything near the lift side of the device .
