USSD codes disabled

justmeagain79 — Mon, 20 Jan 2025 04:20:02 GMT

I use the #*9900* USSD code on my phone to tweak my settings. Lately, I can't use any USSD codes at all!! Is it a carrier issue or are they stopping access to them. This is what I get now.

Try *#9900# this brings up SysDump if that's what you are looking for

Go to Settings - > Security and Privacy - > Auto Blocker and turn if off. You should be able to use codes after that.

Please review what auto blocker does before disabling it since it is an additional security measure.

No dice friend. I also can't access the download screen while my phone is off. I used it to clear cache partition and or factory reset. I can no longer access those options anymore either. It can't be a coincidence.

I can't run USSD codes to access that screen anymore is my point. This is what I get now.

You nailed it my friend!! Will this allow me to get to that cache partition & factory reset(while device is off) etc.?

I do not believe those are related but worth a try I guess! Glad your codes work.

My Samsung Galaxy Note 20 Ultra has no Auto blocker.

USSD cannot be accessed. Any solution?
