Hello everyone,
Many Samsung users face the issue where dialing *#0*# does not open the Test Mode / Diagnostic Menu.


I recently discovered the cause:
The Auto Blocker feature in Samsung settings is blocking the code.


✅ Fix Method:


  1. Go to Settings > Security & Privacy > Auto Blocker
  2. Turn Off Auto Blocker
  3. Dial *#0*# → Test Mode will now open successfully.
  4. If you turn Auto Blocker ON again, the code will stop working.

Here’s the full step-by-step video guide:



This method is tested on multiple Samsung devices (S Series, A Series, Note, Z Flip/Fold, etc.) and works perfectly without root or extra tools.


If this fix works for you, kindly reply with your Samsung model—it may help others.


Thanks,
*~AM~*
