i wrote two apps where there is an exchange of data with microcontroller. These apps have different interfaces: usb and bluetooth. Also apps have the same activity. But! In the first app the activity looks on the all devices the same and scales adequately. In the second app, that has absolutely the same activity ( I took it from the first), some elements of this activity looks differently on different devices ( f.e. colour) and scales differently too ( f.e. CheckBox)
Look images (they made on one device)
Why? How to fix?
