I understand why it is constructed the way it is. However, when I´m in standstill traffic I want to be able to use my phone with both hands without having to reactivate the TJA all the time. Mine often deactivates completely if my hands been off for a little while and does not self-activate when I put them back on.

Thank you for the info!
So, one or two smart screen "dots" glued to a clothes pin or similar may work.
