Hands down I think s7 edge is going to hold its own for a while. It'll be superior to other brands even next year excluding what Samsung puts out. I use a tech21 case with a flap since I cannot find a good screen protector.
I just switched from the LG g5 to the s7 edge and I'm not looking back. I should have went with the Samsung phone from the bat. You can't beat the fluidity of this phone. And the battery seems to hold up twice what I was getting with the G5 and the screen is brighter. I really love this phone.
I've had numerous Samsung phones and they have disappointed me pretty much off the bat. The G5 is my first LG phone and I wouldn't change it for anything else on the market right now. It's a well rounded phone with less issues than its competitors.
Its funny that you just mentioned that. I just upgraded from the nexus 6 to the lg5 today. What I had to do was move them up and down on the back sides opposite ditextions. It took me a couple of tries at the store before I traded in my nexus.
