I updated last night and then wore the watch to work today. Things that happened that have never happened before... 1. the watch called a mate. 2. the watch texted my wife ".8" 3. stopped music I was listening to via my phone/ipods 4. opened various apps 5. I'd sometimes look at the watch and notice it was on a particular screen that wasn't the clock face. Has there been some settings reset via the 4.3.1 update that is causing this? Surely it's not my wrist. Nothing has changed in relation to how I wear it. Could it be the suit sleeve registering hits on the watch? I've never had that happen before. Very very odd. I have done a hard reset but haven't really had a chance to test it out as I'm now at home and not wearing it. Anybody experience something similar???
