System Diagnostics Menu Not Working (*#0*#)

[rrga11]

I have a Z Flip4 running OneUI 6.1. Since I got this phone, I've been able to use the diagnostics menu that is accessed by typing *#0*# into the phone dial pad. Recently, seemingly without any updates between, it suddenly doesn't work. I have restarted my phone and checked for updates. I have cleared the cache of the phone app and force stopped it to see if perhaps the phone app was the issue, and it did not fix the issue. I have done the same with the app that hosts this menu, HwModuleTest. I am on AT&T in the US. A relative has an S21, also on AT&T, that pulls up this menu instantly. Is anyone else having this issue and does anyone know if it's fixable?

Also, irrelevant, but does anyone happen to know when the Z Flip4 is supposed to get OneUI 6.1.1?

Thank you very much! I turned that on recently and didn't even realize it blocked the menu. I wonder why, though. Perhaps because it requires double back button input instead of the usual single back?

idk why tbh but i always keep it on, cuz i dont want my phone to have any malware, i reccomend to turn it off to open the menu and turn it back on when u are done 🙂

Yeah, that's what I thought, too. I'm usually the only one using my phone, especially considering everyone else gets confused by all the gestures I have set up on One Hand Operation+ lol, but occasionally someone else will be using it so I make sure they won't be accidentally doing anything crazy. Another nice thing to change is the setting in Samsung Internet that allows automatic downloads. That might help so that sites can't subtly download things.
