Just preordered my own S7 in black in the UK. Was going to get a deal through Carphone Warehouse but their ordering process inexplicably had issues with my address apparently not matching with my bank (utter bollocks). This happened TWICE.
As a result I looked into other options and saw the Samsung Upgrade Program. Really reasonable monthly payments and interest. It also offers the massive bonus of having the option, if offered, to upgrade to next years flagship phone. Once I source a good sim only deal it costs the same as my Carphone Warehouse deal was going to and cheaper than most deals are now these days (contract prices have sky rocketed in the past year or two!).
So I went through the process and it was surprisingly quick and painless and my order was accepted, so YES I'm in. Also free Gear VR!
I've been waiting for ages for the "perfect" phone and the S7 comes closer than anything else, and good timing as my current contract is up next month. I was considering waiting for the iPhone 7, but poor battery, poor storage increase prices, and the main deal breaker (after battery) is the apparent loss of the headphone jack which is imminent. Screw that, the S7 looks incredible. Best screen and camera, solid battery life, really nice size and ergonomics... Cannot wait to get this phone.
Edit: This reads like a paid for comment, I'm clearly too hyped for this haha!
Also wanted to say Carphone Warehouse lost business with whatever issue they have in their ordering process, I hope someone from there reads this!
