Surprisingly The Best Android Tablet Stand
I have discovered, quite by accident, that the best stand for a 10″ Samsung tablet is a cheap folding picture stand like the one pictured above. It holds the tablet far enough above the surface of the desk so that you have enough clearance to attach a USB charging cable. It holds the tablet at an angle suitable for viewing. It can accommodate landscape and portrait. Most importantly I can leave the tablet in my usb keyboard case, simply folding that out of the way.
I’ve never seen this marketed for a tablet stand, but I can say it works remarkably well. Better than any other solution, and I’ve tried several.
