Since the screws are under the display cover, it is no longer possible to open the housing without damage in order to clean or repair the device. A step back from Texas Instruments!
The models since 2016 have a smaller battery cover. The two screws in the middle are attached under the plastic backside! I loosened the screws with a lot of force and saw that the screws are attached to the front under the display! Does anyone know how to loosen the screws correctly?
