description:

When collecting data in the field with one hand, the save button (✓) is at the top left of the object form. This is particularly true for subforms that are opened from the relationship editor. With the thumb of the right hand, it cannot be reached either in portrait or landscape mode.

This is particularly noticeable when working processes with many linked objects, for example with several photos per area. There, the second hand must be added for each individual entry. Android's back button or back gesture has no effect on subforms and is therefore not a solution.

Suggestion:

A setting under “User interface” that displays the save button at the bottom right of the form, or alternatively a floating save button.

Additionally or alternatively: The back button saves and closes a subform if all mandatory fields are valid.

Environment: QField on Android (Samsung), relationship editor with a linked photo table.
