I too had SDS with Note 2. I had ro pay for new mobo myself as despite the fact it was a recognised fault the phone was rooted so the Samsung service centre spanked me. I got over that begrudgingly.
Knox, yeah well we all know about that. PITA and all but what are you going to do? I know Samsung are trying to pass it off as a security measure and to an extent I get that. The option should be however to opt in or out.
I've had my new Samsung Google Wear watch all week now and I have to say the design leaves a lot to be desired. The charge dock is nothing short of a travesty. I really can't describe how much I hate it. Not only is the design a disgrace but the fact it only seems to function with an official Samsung micr USB charger is baffling. There may be micro USB leads out there that work with it but I've attempted to charge it with 3 official leads and none of them work. I've tried to use a Sony lead, a HTC (One) one and one from my Nexus 7. None work Not quite Apple Thunderbolt but surely getting there? The thing is I would like to charge my Watch and now phone from the USB points on my desktop. Seems this watch will only charge from the brick adaptor that goes into the plug socket. Masterpiece.
