No really a problem per-se, but something to be aware of on any of the new generation "close flat" fold or flip devices. That is, the issue of main screen protection when the device is open. Traditional phone cases have a slightly raised "lip" around the screen. This helps to prevent screen contact in the event of a face-down drop. But these devices are designed to close flat, with no gap between the screen halves, so there is no protective lip. Case or no case, your device is now fully vulnerable to face-down drops. That said, I have a thin yet effective case on my RAZR+ that offers good protection in all other scenarios.
