hey, just got my HiPad X (came w/ a keyboard and a HiPen H3). From what I’ve tested, it seems like the tablet doesn’t actually support pressure-sensitive input (i.e. the stylus works just like a very thin finger - neither of the programs I had used fine with Huawei and Samsung active pens seem to react on pressure).
In addition, when enabling “S-Pen only” mode in some of those apps (used to prevent accidental drawing by fingers/palms) - they don’t react on stylus input at all.
