If you switch from automatic to manual zoom you can calculate an appropriate zoom value based on the ratio between window dimensions set in game.project and the actual window/screen dimensions of the device. Here’s an example of this calculation and how it is used with the built-in camera component (you can use the same calculation for the Orthographic camera module):

Thanks this worked for me. I just changed the zoom on orthographic camera script. Changed orthographic_zoomtozoom property

local DISPLAY_WIDTH = sys.get_config_int("display.width")
local DISPLAY_HEIGHT = sys.get_config_int("display.height")

function init(self)
	local initial_zoom = go.get("/camera#script", "zoom")
	local display_scale = window.get_display_scale()
	window.set_listener(function(self, event, data)
		if event == window.WINDOW_EVENT_RESIZED then
			local window_width = data.width
			local window_height = data.height
			local design_width = DISPLAY_WIDTH / initial_zoom
			local design_height = DISPLAY_HEIGHT / initial_zoom

			-- with max zoom your initial design dimensions will fill and expand beyond screen bounds
			local zoom = math.max(window_width / design_width, window_height / design_height) / display_scale

			-- with min zoom your initial design dimensions will shrink and be contained within screen bounds
			--local zoom = math.min(window_width / design_width, window_height / design_height) / display_scale

			go.set("/camera#script", "zoom", zoom)
		end
	end)
end
