so when i got the G2 i thought man why would they put the buttons on the back how stupid. Well as it turned out i rarely used the back buttons at all with knock on. Now Nexus 6P I have pressed the damn power or volume keys accidentally almost every time i touch the phone. Hopefully the case that should be here tomorrow will change that. But the answer for me is GIVE ME BACK BUTTONS except for finger print scanner that i currently find annoying on the back to unlock phone , But its new to me only had for 3 days so well see if i get use to that.
