I just noticed on my 600+ that the number "4" and "5" in the tens digit get the left side edge cut off in Large font mode in vertical display see images below. I did not see a see a setting for "Zoom" for the large font mode just for graphics mode. Second thing I noticed and it was also happening with Firmware 2.41 and now I have updated to 2.42 it sometimes takes me two times to turn off the WiFi See video. If I toggle "On" First then "OFF" it usefully disconnects the WiFi the first time in the video you can see I toggle it "OFF" and a second later it turns back on.
