I’m developing an app with some material icons and runs properly on my mobile phone and on my tablet.
I also did a test on another tablet (cheap China saying that is Android 8.1) and some icons are not displayed. That happens on: swap_horiz swap_vert highlight highlight_off
In fact, only the record_voice_over icon is displayed correctly.
Seems like version of Material icons ttf problem?
Is there anything to do to bypass this problem except to download the .svg image icons?
