DSO Nano v2 Adjust DOWN button not working


I just received my DSO Nano v2 today. I was able to turn it on, but for some reason every button appears to be working properly except the ADJUST DOWN button. It is just not responding at all. Please help.

Have you tried pushing it few ways. Llike on the edge or little harder? Maybe it was soldered not accurately. If does not work then you will need to have Seeeed fix it or take it apart and check solder points and resistance of that button.
