Been using Secret Codes For All Mobiles for a couple months now. It’s basically an app that gives you all the secret codes and hidden menus for Android phones. Pretty solid if you’re into that kind of thing.
Here’s what you do – you can look up codes for your specific phone model and brand. And there’s also a section with general USSD codes that work across different phones. Took me a while to figure out some of the codes but the app makes it pretty easy.
Look, if you’re into customizing your Android phone and unlocking hidden features, you’ll probably like this. It’s not perfect – the ads can get annoying if you don’t pay – but overall it does the job. Worth checking out if you wanna access those secret menus.
