Pressure Sensitivity not working on Huawei P9 #9

Open johnnyluu opened 7 years ago

Loved the app on my old phones and tablets, but the pressure sensitivity doesn't work on my new Huawei P9, which renders the app unusable. Very sad. Is it possible to fix this?

When you turn on Debug mode in Markers, do you see any variation at all in the numbers on the left-hand side of the graph?

Pressure is always 1, the last value changes.

If the number changes at all, even a very small amount, over time Markers should adjust to it and give you pressure sensitivity back. (You have to do a lot of drawing to train the app.) But if it's just "1.000" forever, no matter how hard you press, then the screen is just not reporting pressure data at all and there is nothing Markers can do.

Yea, the text is pretty hard to read because it's tiny, but looks like the the first value is always 1.000. I kept drawing for 3 minutes and nothing changed. I guess I'll just have to accept the fact that it's not gonna work on my phone now. Thanks for the help.
