I have an original Venu. In fact this is a free replacement since the original's device screen just stopped working one day and support replaced it. I'm now out of warranty.
At weekends I often charge the Venu overnight, because I don't need to wear it as my alarm clock then. Recently it has developed a habit of ringing the alarm at 6.30am - despite me having no such alarm configured! I've also had similar ghost alarms ring at 11pm.
This is driving me mad, waking me up when I want a lie in..It also wakes my wofe because the watch is charging on a hard surface and vibrates loudly.
Has this happened to anyone else? I wouldn't expect anyone to believe me (including support) but I can't accept the watch waking me up at random times I haven't requested.
