Display and few other issues

Even though the display looks very good, I have some issues with it.

  1. It’s too bright even at the lowest settings. I tried to download severeal external apps, but they seem to be buggy on this device, crashing all the time etc.
  2. WiFi connects to a weak 2.4 Ghz signal even though much stronger 5 Ghz signal is available
  3. Can’t change navigation button order
  4. I would love to get rid of the annoying Google Assistant from the main screen.
