Just lately, like in the last day or two I've had an annoying issue pop up with the slide out keypad on the moment. When I pop it open one handed it shuts off the phone. Seems like a mechanical issue because it doesn't power off, it just goes out like the battery is disconnected somehow. If I slide it open carefully it won't do it but it does seem to be getting more sensitive. Has anyone else experienced this or know of a work around? Obviously just using the pop up keyboard is an option but not as convenient.
