I haven't changed any settings on my phone other than increase the size of the font to maximum and using dark mode.
It's a Motorola Moto G31 with Android V11
If I use the wifi analyser that others here use, my Wifi shows this -
Skyd-NN(ec:**:**:**:**:**) <- normal solid font
-60dBm CH 11 2462Mhz -6.9m <- only CH 11 is solid font <picture> 2452-2472(20 Mhz) <- 'funny' font, plus above line
The neighbours show similar but the first line is
[WPS WPA2] <- in funny font.When I look at my test results on SYSTM Online (or what ever it is called), the actual result values use this font and the usual method of stretching the screen does not work.
