The valve does not close. the magnet is probably not powerful enough. It's very annoying. The application is very basic and not very configurable (I pass on automatic translations in French more approximate). No notification, no sms, but access to torch mode (nice but not essential). In any event the valve glass does not allow the application or manipulate any case very difficult, short unusable. I reference everything. Too bad because otherwise the protection level of the phone it had properly compared to that proposed by Sony.
