Hi,
is there any other unwanted screen action you notice?
When does it happen exactly, under what circumstances?
If when holding or interacting with the transmitter, how or when exactly?
Technically, there are two ways to take screenshots, assign a switch, or do a three-finger-tap.
If you have assigned a switch, de-assign, or assign a different one, and see if it makes a difference.
If not, please disable the Screenshot App and instead, enable and activate Screenlock, see if that activates randomly, too.
Are you using a screen protector of sorts? Could be possible that some are somehow interfering with the capacitive digitizer, even though I have no precedence yet.
Unresponsive could simply be that the transmitter is working off queued instructions (a series of screenshots), and during that time, does not accept further commands.
Kind regards
Eddi
