On all devices with a resolution of 400x800, 480x800 tablets, the layout is displayed correctly, but there is such a fly fs406 stratus 5 device on which the lower elements run over the upper ones, as if there is little space, although they are still inside the scroll view , on all devices that are missing everything is scrolling, but not on it. What could this be?

Correct display:
How it is displayed correctly on all devices

Display on fly fs406 stratus 5 :
How is it displayed on the fly

    So many Chinese and not very baffling machines. General construction

     <ScrollView> <RelativeLayout> </RelativeLayout> </ScrollView>

    It has long been a lot of questions. The overall result - it is desirable to avoid this. Consider the layout, according to your examples it is not clear why the relative placement, everything can be well put together in LinearLayout. As a crutch, I was helped to wrap up the internal Relative in Linear and, spitting on the warning of the medium about the meaninglessness of such a design, assemble the application working on the “curves” devices. Try it, maybe it will help you.

      here because

       android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_alignParentStart="true"

      try to add

       android:layout_below="@+id/fmt_create_car_spn_beacon_type"
