Once I run the Google Maps on my Samsung fold2
phone with the created app running ( by you ;))
it automatic starts google map on my Samsung Notepad via bluetooth or what ever connection is BEST.. (distance will be short)
On the Samsung notepad
user has only access to update address on google maps and send a message to samsumg fold2 on the bottom of fold2 screen
Both screens running google maps are mirroring
I Guess we need remote software running and ???!!!!
Should be a easy project
