I also use openScale from F-Droid, in combination with this Bluetooth scale:

That is not entirely correct. The reported found the app using permissions that are not covered by the manifest. It also found the app being capable to execute arbitrary code send by temu. So it cannot be clearly answered if the app can utilize these permissions or not. Obviously they would not ship such an exploit with the app directly.
