way out

go to safe mode,
you can googling how to turn safe mode based on your handphone type
and then back to developer option menu, on simulate secondary screen choose -->> none
and restart your phone

it works for me

I have the same problom to, i can’t even go to the control center!!!, I tried doing a force restart, but i did NOTHING, So i will wait for it to die so i can try to go in recovery mode, I want android to remove this feature right now! This feature is seriously dangerous! So now i can’t use my phone?! IS THIS FEATURE PERMANENT?!

Well, I'm answering your question from 2023 lol..
First of all you need to turn your phone into 'safe mode' - This safe mode is just like an emergency exit from rough situation.

There are two ways to turn on safe mode.
1. Press and hold the power button
- you'll see two options; to 'power off' or 'restart'
2. Press and hold 'power off' for some few seconds
3. The safe mode interface will pop out asking you whether to 'Reboot to safe Mode'
4. Click on 'Okay' or 'Yes' (But if your screen monitor is not allowing you to click the area, see option 2)
It will reboot to safe mode,.then you can operate your phone and deactivate any developer option setting you did...after deactivating turn off developer option if you want and then 'restart' your phone, it will come back to normal.

Option 2.
1. Turn off your phone by any way you can.
2. Now turn it on, immediately it starts the animation or 3 seconds after you switch it on,.
Press and hold the 'volume down button' until your phone vibrtes
This will take the phone to 'safe Mode' then you can undo all your settings, then restart your phone..

Thanks for reading, I hope this helps? You can email me promisesilver3@gmail.com

Safe mode is the only way...
Power off and then turn on and press volume down key.. and fix the issue in developer option
I also faced this issue and now I fixed myself
