Find serial number of Samsung Galaxy S7 edge How can I find out the serial number of a Samsung Galaxy S7 edge without the sticker on the phone / box?

I've tried a few 'secret codes', but nothing happens when I type them in:

I've tried downloading Kies on my computer, but it says my phone is unsupported and I need to download SmartSwitch. I've installed SmartSwitch on the phone but it doesn't seem to be for verifying the phone.
I would suggest you try using Phone Info Samsung. It is a very versatile app and gives you a lot of information on Samsung devices (many may come as a surprise). I have used it for four years on my previous devices. Developer has an active thread at XDA

Play store  snapshot claims that it displays serial number too. It did that on my old Note 2
