Hi,
I think this has been reported already: https://bugs.kde.org/show_bug.cgi?id=424347
I haven’t looked into it deeply, yet. But this is something which started happening on my devices as well. I am not sure if this is a regression caused by something in Krita or something else 
Oki thanks for info
ive just updated krita for android.
pen pressure for huion kamvas 13 still not there.
is there any idea if this will be added in not so distant future?
pressure works with infinite painter for example on android.
i would rather switch to krita as its better then infinite painter but pressure is something that is much needed for drawing
