I just checked my order's through Best Buy and both say this;
Status: Pre-ordered
Expected release date: 03/11/2016
I ordered two Titanium's (AT&T). Both phones were ordered at the same time/date. Feb 23rd right around 8:15 ish. Maybe going directly through a carrier is allowing for faster shipment. I'm OK waiting until the 11th or a day or so after. I've waited this long for the release, so what's another couple weeks? I'm just excited to get it. I'm coming out of a S6 edge. I personally love using the S6. The camera is my favorite feature of this phone so making use of the f1.7 is going to be great with the S7. I only use the edge screen now as my clock when I'm in bed. I have it set to automatically shut off at 6am. So when I hit snooze several times in the morning and don't see the clock anymore, I know I have to get up! The always on display is a huge plus!
