I occasionally kept my Dingoo in my front pants pocket. This worked fine for a few weeks, but one day I pulled it out to find that the LCD glass had cracked. When the unit is off, it looks perfect without a scratch as I kept it in a plastic bag. I am not sure what caused the screen to break as I don't remember anything resembling an impact between uses. The same pocket also had an iPod Touch and what may have happened is that when I sat, my pants pulled around my leg and the unit was slightly bent around the iPod (which is the first generation, a thin and flat device). But the crack was vertical near the center, which shouldn't be where the pressure might have been. My pants aren't particularly tight, either. There was also one point where I had slipped the unit into a bag in my car, but I don't think it was particularly jostled. I treated the Dingoo with more care than my other pocket electronics, such as my 4 year old cell phone which is still going strong, and the iPod which has plenty of scratches but works fine even after I dropped it on a hard tile floor. Of course, with this kind of overseas purchase, the buyer must beware.
On a related note, I am not sure what to do with this thing. Should I try to replace the screen? Does anyone know of a compatible part? I think I can do this as I have disassembled/reassembled electronics and done some soldering. Or, should I sell it as a TV Out only device?
