My screen is white but the phone and alarms still function!

Shortly after Covid-19 started my screen resolution and colors started fading, and then I completely lost the displays on BOTH my Z221 (wife’s old phone) and Z222 (all made in Wahun, China where Covid-19 started). The alarms and phone still function and I can only answer it if I happen to see it while it is ringing…help!
