You used to be able to use the ##4636## trick to get a hidden menu, but now that’s gone too. There’s nothing in the menu that alllows you to select which network to use. I hate to keep having network disconnects and in perpetual 4G/5G back and forth and battery draining.
I use Samsung btw
Edit: For context: Its due to issues with being near the edge of the 5G zone so your phone keeps going back and forth between 4G and 5G which (I suspect), is what causes constant network disconnection, phone being hot/warm, and battery drain. Very annoying.
Edit: YOOOO I FUCKING FOUND IT

Search “Phone Info” --> Click the one with the phone icon --> Click again (there should be only one option --> Launch Activity --> Fina a dropdown option, change dropdown to LTE
Voila. I feel like a fucking hacker (why is this so hidden wtf Samsung?)
That is not Andy but is a Samy thing. I can still turn off mob nonsense in Graphene/Andy and leave it off all the time because I can’t control it as well and don’t have a proxy setup. The SoC and modem are undocumented proprietary nonsense on all mobile devices so no one can be absolutely certain of what is or is not connected.
