You know I just figured out a magnet in my case is messing with my pen. Tablet uses some sort of sensor to detect if your pen is in or out of the tablet. Pen has been crazy the last 2 days. Sometimes it works sometimes it wouldn't. I'd put it in, pull it out and sometimes it would be fine. Real intermittent to where I thought I was imagining things. So I turned up the system sounds so I could hear a noise when the pen is removed. Well when I have my case folded back on itself, one of the magnets is pretty close to the pen slot. It's close enough that if I put any pressure on that corner of the tablet, I hear the noise like I just put the pen away. I can get it to do it consistently, and didn't realize because I had the sound effects turned down.
I have the tablet set to not detect the pen when it is docked as it is supposed to save battery. If I change this setting it most likely would not be happening, however, I don't like the fact it is fooling the sensor.
Just thought I would share in case anyone else was having a similar problem.
So I take back what I said above, my one magnet is messing with me due to its location. If I have my case in any other orientation there is no problem because it is away from the pen slot. Atleast I'm not going crazy!
