This is to show Google how many users truly desire the ability to have the following in the iOS version of Google Maps (which is / is not already implemented in the Maps.app by Apple):
1. Add a killswitch option to disable (or enable) the Automatic brightness level adjustment
2. Increase the volume level of the turn-by-turn voice navigation, so that it can actually be audible, without the volume being at high levels (or if possible: decrease the volume of the currently playing background audio, like the Maps.app does)
