PROS: Looks good. Takes Great Pictures. Curved screen is nice, kinda. Sometimes the screen would do some weird input touches from the sides of my fingers wrapping around the phone. Hardly a cause for concern though.CONS: TERRIBLE cell service. No IR blaster. Back glass is FRAGILE!I have been using the Galaxy series of phones since the S4 and have enjoyed every variation until this complete disappointment of a phone. I can hardly even call it a phone since it would need to reliably make phone calls to be considered one. I don't live in some rural area countryside with poor cell service to begin with either. In fact quite the opposite. The suburbs of Long Island, where even when signal strength is a paltry 1-2 bars I could always make/receive phone calls and connect to the internet on the mobile network with my older devices. After battling with ATT about the network issues regarding this phone to no avail I am back to using my trusty old S6.I tried and tried using this phone hoping updates (there were 2 system updates) would address this issue. They did not. Over the weeks of use I would constantly need to restart my device to regain network connectivity. I would frequently have 2,3 or 4 bars of signal showing on the phone and no cell connection. In 1 instance a call dropped while driving on the expressway and the phone had not regained a cell connection for nearly 9 miles. 9 miles of the crossed out circle showing what this phone was truly worth. I had never had so much as a dropped call on my S6. Not once. This phone dropped calls daily. Text messages will flood in 3-4 at a time when the phone decides it is finally time to let you know people have been trying to get in touch with you all day. There are even times when on a 4G network connection with 3 bars the network connection doesn't work. (Pictures attached). That is the worst of this phoneNearly equally as bad is just how delicate the rear glass is. I never used cases on my S4, S5 or S6. Sure they would fall from the night stand from time to time but they would always hold up for as long as I had them. Cracks would develop over time from these mishaps but I am not even entirely sure the S7 Edge can survive normal use without becoming damaged. When I first had these network issues I figured I could always just resell the phone as used and cut my losses. This was mere weeks into using the phone. It was never dropped or misused. When I decided I could resell it because it was "basically new" I carefully inspected the phone all over for any signs of wear thinking maybe there was a micro scratch or something from sliding it in and out of my pocket. Even worse. There were 2 single line cracks starting from the outer edge of the back glass traveling inward towards the center. NEVER DROPPED. I have no idea how these developed and had not noticed them before considering unloading this phone but they appeared to be stress cracks from flex. No defined spider web cracks indicating impact and honestly the phone was not dropped onto a hard or soft surface from even an inch of height. I decided I would just continue to use the phone and hope it would get better. Over the month and a half of use it did sustain one slip off the couch onto the floor and the rear glass now looks completely shattered. MY old S6 must have slipped off the bed or dresser at least a half dozen times in the last year and all it has to show for it is 1 crack along the back that you would not notice unless you really inspected it for damage.Maybe I just got a lemon in regards to the cell signal issue. There are plenty of people that have this phone and love it. The rear glass issue is probably something not isolated to just a few units though. This phone is not one to be used without a case of significantly rugged design if you want to preserve the back as crack free.
