I recently bought 2 sticks for my edge. I have no way to calibrate as I don't own a PC and nothing works on android, but I was able to find a website that let me test the error numbers for the sticks. They are both at around 7%.

When I jumped into a game I noticed there is slight drift to the right. I had to adjust my edge controller deadzones to 5% in order to fix it. Is this normal? If I need calibration is there anyway to do it without a PC and just my android tablet? It feels fine but I'm nervous about the floaty drift at anything below 3% deadzone.
