Some developer options cannot be set
Under developer options, there is a toggle "SSID Bridging - Fast Handover" in the Networking section. Since Android 12, I cannot set it on. Every time I toggled it, when I came back later, it was still off.
Then, in the Hardware accelerated rendering section, there is a toggle "Override force-dark". Although I can turn it on and it stays on, but every now and then it would revert to off without me changing it.
These behaviours are just very strange.
