iPhone 12 Personal Hotspot "Maximise Compatability" Switch - 5GHz / 2.4GHz WiFi toggle

So I came across this new switch on my iPhone 12 in the personal hotspot settings, whilst trying to get my phone to link to my car SatNav.


The description on iOS says "Internet performance may be reduced for devices connected to your hotspot when turned on". Not exactly a 'user friendly' description!


Quick internet search confirms (not found on Apple sites!) that the iPhone 12 defaults to 5GHz WiFi for personal hotspot and the switch is used to flip this back to the 2.4GHz WiFi network, which I needed for my vehicle's SatNav to work.


Posting this here in case it helps anyone else who may and themselves in the same situation.


As an aside, there is no option to 'long press' select this via Control Centre, like you can with Wifi, Bluetooth and Airdrop sub options, so I have submitted that as a feature request to Apple.

iPhone 12 Pro Max, iOS 14

Thanks for your reply, but my post is not to do with the iPhone 12’s ability to connect to a WiFi network over 5 or 2.4GHz, rather it’s ability to act as a Personal Hotspot for OTHER devices to connect to it over WiFi and use it as a personal hotspot.


All iPhones prior to iPhone 12 only offer 2.4GHz as the hotpot network.
