    The latest one is 1.0.7 from July.
    Could you please add setting for disabling the start-up beep sound? Or just disable it forever it is useless and annoying. Thank you.

    The latest is now 1.0.9, so try update. Blue LED is flashing when SD card is being formated, so maybe you need to format the SD card? Or the SD card is too slow? I use Patriot 64GB V30 and seems to be working well. Very good micro SD are also EVO Plus from Samsung the U3 version, the U1 version is also good and should be more than enough for this camera. Otherwise I don't know what the flashing blue indicates.
