Going by usage, buttons should be place either close to the subject where it refers to (like the close to the phonenumber) or close to a place where the thumb will be comfortable to use.
The screen I have defined, I am wondering where I should place the "call me" button. I have placed it below, I wonder if its most intuitive. Also note that this is the only screen the customer will have a chance to call the driver. Before this the confirmation is under process.
As the app loads, the user uses all their fingers (to enter the destination). After that this screen appears as a FYI. Calling the driver is the obvious default behavior. I wonder if I should rename the GotIt to something else like, LATER. Or Thanks. This action will save the ride to
booking status list.
Edit Again : This screen appears when the customer wants to know the status of the driver, ride or just talk to the driver.
