[Bartmans]

I have an almost 10 years old tablet (Samsung SM-T820 aka Galaxy Tab S3, Android version 9), one of the first with a pen stylus and 9.7 inch display; pretty old indeed but still a nice device to me.
Recently I bought a Lekato WT-1 bluetooth pedal and now at unexpected moments the Android text keyboard pops up when I press the left pedal (configured as page left). Already tried to contact Lekato company but they do not respond :-(
Any suggestions?
