Is anyone else using Krita in a Samsung S8 Tablet?
I am having problems with the S-Pen. It does not seem to be using pressure. I am trying to match my Samsung Krita to my Wacom Mobile Studio Krita.
But the curve in Tablet Settings on the Samsung is opposite the curve settings on the Wacom.
This screenshot is from the Samsung. This curve is a convex curve.
This screenshot is from my Wacom. The curve is concave.
Am I missing something? Use pen pressure is on on both systems.
It’s been my experience that trying to match pressures from different devices is an exercise in frustration. I’ve tried matching my tab s9 ultra to my huion on windows and ended up noodling away at the pressure curves for hours before finally giving up and just dealing with the differences. 
I realize that’s no help, that’s just been my personal experience.
Sorry but those pens feel extremely different, there is no point in trying to match the curves.
Smooth screen and rubbery tip vs. Etched glas and plastic/felt tip I don’t see any possibility to match their behavior… One of the both will be your favorite either way 
You mean you don’t have any pressure sensitivity at all?
No. Sensitivity does not seem to be working at all. I thought it was the curves. I am now realizing sensitivity is not working.
I am going to trying reinstalling Krita and see what happens.
Not really trying to match. Just get sensitivity to work. If I get that far, I can adjust the brushes from there.
You haven’t by chance disabled the use of pen pressure in Krita?
… and, by the way:
Nothing will happen. I may be wrong, but it seems like you have not understood the way Krita works.

can you confirm the pen sensitivity works in other apps? and have you tried the standard, ‘turning it off and back on again?’
Krita is working fine on my Wacom tablet. So it is not an issue of understanding how Krita works.
Your believing in a reinstallation of Krita for fixing things shows something different. Or in other words, a reinstallation will not solve any issue in ca 99.99999% of all issues with Krita, maybe even more nine’s behind the dot.

Krita isn’t running on your graphics tablet tough, it is running on your computer (or whatever you have it connected to), the tablet’s driver (running on your computer as well) takes the signals and translates them into understandable events for Krita (more precisely Qt I guess). The same goes for the S-Pen. Normally when an input device is reported not working here it is 99% of the time an issue with the driver.
So I don’t know much about Android or the S-Pen, I can’t tell you if you have to install a driver on Android first or set up a profile for Krita (like Wacom sometimes requires on Windows). First you should check if your pen actually supports Pressure. From just quick googling I found there are two types of s-pens, one that is basically just a replacement for your finger (no pressure) and another one that is pressure sensitive. Then you should check if pressure sensitivity is recognized in other apps. I believe I read somewhere on the forum that there is a native S-Pen App you can use for testing. If all of that works, make sure pressure is not turned off globally in Krita. I don’t know if the tablet tester is available on Android. In Krita’s tablet settings there is a button to bring up a little debug window for pen input, it will tell you something like pressure, coordinates and button presses of the pen. Check if it also recognizes different pressure levels (shown as percentages).
This way we can see at what point it stops working.
Let me say this. I have been working with computers since 1984. I am not a newbie, novice or whatever.
Don’t make judgements on my knowledge based on a paragraph for an issue.
Second, I did reinstall Krita and it DID fix the pressure sensitivity problem. So in this .01 %, it worked.
I reinstalled Krita and pressure sensitivity is working now. Just not the best. I think at this point I have to play around with curves and see what I do with it. I do understand the whole driver thing.
My S-Pen does support pressure. I have another program that I use to test it with. It is a basic program but it shows pressure.
My Wacom is a Mobile Studio 16 running Windows 10, which is a self contained computer tablet. But next year it becomes a boat anchor as Microsoft is discontinuing support for Windows 10 and my version of the tablet cannot be upgraded hardware-wise or to Windows 11. So that is disappointing.
I just wanted to use my Samsung for sketching and then moving the images over to the Wacom to finish.
Just right now, the Samsung line work is so significantly different from the Wacom I end up tracing over the original sketch from the Samsung instead of building upon it.
Nobody is preventing you from continuing to use your Mobile Studio Pro with Windows 10 and doing almost everything with it as before, I just wouldn’t use it for Internet access anymore. And I probably wouldn’t use it in a network with Internet access anymore, and if I did, then only with extremely tight security.
Regarding the reinstallation, I overlooked something, at least if I understand it correctly. It was a reinstallation under Android and not under Windows, Linux, macOS. If this is the case, then a reinstallation can be much more promising than on the desktop operating systems and is related to Google’s paranoia. But that’s another story.

Yes, in October 2025. That means it won’t get updates so it won’t get broken drivers or any other annoying changes forced on it by Microsoft.
That sounds good to me 
A month ago I used Flyby to upgrade my Wacom Mobile Studio (Gen 1) to Windows11. It works great. Actually, Rebelle 7 now works better than it did on 10.
