Do you mean Android 9? I was trying to read some text on many smartphones at supermarket, from budget to flagships and this issue seems to be totally random. Like for example there were some pretty nice IPS panel in Motorola smartphones and some of them had this oversharpened text, some of them no oversharpened but with supposedly BGR font smoothing instead of RGB (text had this reddish-greenish tint).
This is pretty absurd on high dpi screens… And probably font antialiasing can be changed during Android updates to some other settings, probably still chosen by accident by phone manufacturer.
To do justice - in iPhones text rendering and default fonts are much more polished.
