Capacitive Stylus on Venue 8 Pro 5830

Hello,

I own a Venue 8 Pro 5830 and it works fine with the fingertip and with the active pens (well, acceptable in this case), but when I try to use a capacitive pen, it doesn't work at all. I tried a Genius light foam, and it interpreted the single touch as an infinite number of touches. Next I used a pen with a stiffer rubber tip, but it didn't work as well. I purchased a jot capacitive stylus, the one with a capacitive plastic disk on the tip. It did work relatively well, but with constant multiple clicks when I type on a keyboard or when I draw a line in Onenote.

I already calibrate the touchscreen in the windows 10 itself, as well as change the latency in the registry, but it didn't work. I also removed my screen protection to touch directly on the screen.

The reason to buy this tablet, was to have a more potent mobile device for reading, noting and sometimes editing, but the pen use an AAAA battery witch is rare to find, the touchscreen is supersensitive or insensitive to capacitive input devices and the USB connector already have a broken tip due to strange port shape. I have to say that I didn't buy a Galaxy Tab A in favor of this model, but i almost regrate now.

Does anyone had the same problem?
