Nexus 7 ok for video when you find the menu app

I have bought a Nexus 7 from Tesco in Exeter. So not very adventurous.

For about an hour I could not find out how to work the camera. Then I used search on my desktop and found this

Not sure why there is no icon to start with but now there is. Apparently the camera will pop up in the middle of a Google app but not just as it is. Search also shows a hack to improve the resolution but this is ok for quick clips of comment.

the lighting will improve outside. Wifi ok in much of Exeter.
