ok, a quick tip for anyone else that wants to copy data to the watch.... do NOT use a USB hub, plug the phone directly into your mobo usb ports. I've been trying to copy the latest update to the watch for a while but it kept stalling for no reason. Tried adb push, same issue! Then, finally tried plugging directly into the computer and bingo, worked first time!
May just be the hubs I have, but they are d-link ones so are fairly decent.
Most usb hubs to not provide enough power so its always safe to connect directly to computer, same goes for charging the watch.
It is a powered hub with 1A ports, but yes, good tip for general hubs.
Anyway, I have a bug report for you to pass on. Latest v3 firmware:
The Weather App, Selecting United Kingdom, then Brighton & Hove (my nearest city) as the location will cause the weather app to go into a crash loop. Only a reset to factory defaults will cure it. I assume it is because of the '&' in the description. If they can change the city name to just Brighton then I'm sure it'll be fine.
For now I have London selected as my nearest city and it's working ok.
Powered hub should be fine, maybe another bug on Z1.
I have posted the bug in the forum and will forward to SmartQ, it can take some time for next update as China is going for the longest public holiday of the year, Chinese new year.
Let me know if you find other bugs or interesting findings.
