We received the information from @belidzs that the latest Android update fixed the problem.
I guess this is an Android firmware problem and encourage everyone with this problem to update to the latest firmware version as soon as possible.
Does upgrading Android fix this problem for other affected users here, too?
Output from sudo libinput list-devices | grep Device ...
libinput error: event17 - Network Tablet: libinput bug: missing tablet capabilities: resolution.Ignoring this device.
I tried starting the driver and device in a different order, in case resolution isn't set until the device first connects, but the error remains.
Is there any additional info I can provide to help debug this?
