Wrong りon android ?
i've been doing some of the exercises on phone and in Hiragana 2 i've been getting i different symbol for ri https://imgur.com/a/00I5vl4
is that correct ?
That's how りis commonly written in computer fonts. It is still two downwards strokes, but it is meant to resemble how it looks when you handwrite it (quickly) with a brush: the ink trails in between where the first stroke ends and the second begins.
That is really not clear in that font though; it shows up better in ones like MS Mincho: https://imgur.com/gcXnprp
