“Win Descent” and “Win Ascent” are not working in Android devices. One must edit this in .ttx format xml file.

The two values are in tag as follows:

  <head>
    <!-- Most of this table will be recalculated by the compiler -->
    <tableVersion value="1.0"/>
    <fontRevision value="1.0"/>
    <checkSumAdjustment value="0x57f6e15f"/>
    <magicNumber value="0x5f0f3cf5"/>
    <flags value="00000000 00000001"/>
    <unitsPerEm value="2048"/>
    <created value="Sat Feb 24 23:07:45 2018"/>
    <modified value="Fri Aug 20 11:00:01 2019"/>
    <xMin value="-2059"/>
    <yMin value="-586"/>
    <xMax value="6024"/>
    <yMax value="2357"/>

    <indexToLocFormat value="1"/>
    <glyphDataFormat value="0"/>
  </head>

You can not manually adjust yMin and yMax, as those are calculated fields according to the specs. If Android behaves badly, then that should be reported and fixed.
