I'm not sure if this is a Z30 thing or an OS thing so this thread may have to removed. For some reason, whenever e my Z30 in the holster pouch, it automatically turns off the vibrate. Ideally I'd like it to vibrate in the holster and ring when not in holster. At worse case, I'd like it to vibrate and ring inside and outside the holster. But for whatever reason, the vibrate function turns off when it's placed in the holster. Any help with this?
