I can dial codes like USSD codes for things like getting imei numbers and such using Dial or Call intents, but what about other codes like hidden menus and such? On one of my phones I dial a number that looks very similar to USSD, but I don't have to press send at the end, the dialer just detects it. I can get the number to appear in the dialer with an intent, but it doesn't execute the needed process. I can even delete one character or the whole thing and retype it and nothing happens. It is like the dialer that opens with the intent isn't even checking for a code??? Anyone know how to make an intent to dial those kinds of codes?
