Re-enabling Developer Options So, I am trying to reset my security questions on my Huawei Nova 3i phone by reseting the settings app, only to find out that I also disabled/hid the developer options. Tapping the build number again makes it only say that I am already a developer. Any suggestions on how to fix this? Without factory reset. Thanks!
This is not a way to get Developer Options back, but a workaround to launch it. You'll have to this again from Step 2 below every time you want to launch Developer Options.

You can use the ADB method @Robert referred to if you had USB debugging enabled, but based on your question it looks like it is disabled. If it is disabled or you can't use ADB for some reason, you can try the following method:


You'll have to download and install a third-party app, Activity Launcher from Google Play Store.
Open it and choose "All Activities" from the drop-down menu.
Scroll down until you see "Settings" and choose it. It will open an another drop-down below it.
Again scroll down until you see "Developer Options". There will be two menu items of that name.
Choose the first "Developer Options" item. If you want to be extra sure, the light-grey text below the correct one is com.android.settings.Settings$DeveloperSettingsActivity.
That will open the Developer Settings Menu, and you can do what you want there.


Note: I tested this on a P Smart Plus device (which is just your device with a regional change) so it should work on your device too. Also never launch random activities in Activity Launcher! It could damage your device software badly.

Good Luck!
