Background grid lines in Quarderno A4
I bought a fujitsu quarderno A4, which is the same as the sony dpt-rp1.
The problem is that the background is not white (or gray). Actually there is a background grid of lines in all the screen. Is this a production problem? I there any way to remove them ? I like the device and I don't want to return it but with those lines it is not usable for me.
Thanks in advance!
