Also if not strictly related to framework7…
While all material icons are displayed in browser, I noticed that
quite some of them aren’t visible on old mobiles and/or old android versions.
For example the ‘show_chart’ icon is displayed on an Huawei P8 - Android 7.0
but not on an old Samsung with Android 4.4.
There is a correlation between Svg icons and the different PixelRatio of the two mobiles (3 vs 1.5) or what else ?
