Darawing pattern on mobile screen

I need to draw a signature on mobile screen. Please keep in mind that i cannot use set text activity. I need to literally draw a pattern which mimics a signature.

How can i acheive that? I tried using Draw patten activity which is not giving reliable results. the behavior is inconsistent.

Are there any alternatives?

What do you mean by “inconsistent behavior”? Can you give more details about the problems you are having with that activity?

There is always the option to call the Appium server directly (using a HttpRequest). The “touchPerform“ endpoint should allow you to manually specify each segment of your signature individually, but this can be a very tedious process (unless you have a very simple signature).
