Menu to do what? Once in an open app, "MORE" usually gives you options.
If you're on home screen and want your apps, there should be an icon with the nine dots in a circle kinda like a domino...
Other apps may have three dots lined up vertically...

Not true. My s7E has no menu button my my MOTO Z Force has it in apps that have had it before, running 7.0. My Nexus 6 has it but has not upgraded to 7.
Just got my s7 edge yesterday and the pesky missing menu button had me perplexed too. Verizon tech support is clueless , I had to search around a bit, but the answer is, for apps that don't have their own ... Menu, the back arrow, long press does the trick. Wonder why they took that away and gave us a separate button for recent apps, when the home button long press did just fine.
