In what scenario is that useful?
For me it goes like this:
- Where I work we have a wifi that is so slow it’s useless. If I need to use my laptop I put my phone in access point mode. Then if the phone runs out of battery (or boots for some other reason) it’s in client mode when it returns and connected to the worthless wifi.
- When I drive the car is connected to the internet trough the phone (for traffic flow reports and rerouting). If the phone boots I need to stop the car and reset the wifi into access point mode or, if it isn’t possible to stop, surf through the setting menus while driving.
