Please describe the problem you’ve encountered in detail:

  • Description: I, some days ago my fydetab duo started to not register the inputs from the stylus, first i though it was the battery, so I ordered some new ones, but now even if I use the new ones it still doesn’t work.
    I don’t know if it’s related, but usually I have the pen on the back of the cover (the up left side, since it’s magnetic)

Thanks for the report. We haven’t been able to reproduce this stylus issue on our side yet. Could you help us with some logs so we can debug further?

this is the log, I tried to touch the screen with the pen before opening it.

Could you please downgrade to FydeOS v21 on your Fydetab Duo and check whether the stylus works there? This will help us confirm if the issue is version-related.
