What are these hidden codes for Android?

USSD codes

Behind the USSD code is not the actual hidden codes hide, so we first have to make a distinction here. Behind USSD, the term hides "Unstructured Supplementary Service Data"So unstructured service and control commands. These send a signal through one of the mobile networks and get an answer from a distance; then you get, for example, told how much prepaid credit still remains to you, or if your mailbox is activated.

To type in the code, you simply open your phone app, bringing the number key to the fore. The usual USSD codes start with an asterisk ("*"), Or a pound sign ("#") And end with a diamond. A currently maintained list of key codes for the provider in the German-speaking countries is maintained on Wikipedia. Otherwise, the providers deliver their own lists of codes.

  • GSM and USSD codes Telekom
  • GSM and USSD codes from Vodafone
  • GSM and USSD codes of O2

It's always free to use this code, no matter where you find yourself. But the USSD codes also have a dark side. Because in 2012 it happened again that the Samsung Galaxy S2 and several other smartphones could be remotely reset. Because you could then tap a phone number link that is embedded on a website, and then an Android code triggered to reset to factory settings. For this design flaw has been learned, of course, but turns out that there have those little number combinations quite a kick. And that is not less explosive with the codes from the upcoming section.

The main USSD codes:

  • see prepaid credit, Telekom or Vodafone: * 100 # ✆
  • see prepaid credit, O2: * 101 # ✆
  • Check own number, Telekom: * 135 # ✆
  • Mailbox off Long ringing, telecom or O2: ## 61 # ✆
  • One-time suppression of the call number: # 31 # Telefonnummer✆
  • Status of the calling number: * # 31 # ✆

The system code

With a minimal different form, namely a "* #" or "##" at the beginning, Android offers its own system code. This directly access the Android system to (who would have guessed that?) And therefore require no connection to the outside. They are also not only by pressing the green handset, but after pressing the final "#" or "*" executed. Your IMEI you get then this:

* # 06 #

What you notice, hopefully, is that the code will not run automatically by your phone app. And that's a good thing. It is precisely through such a link could then reset the phone to its worst enemies completely, if you wanted.

Below you will find a list that includes a number of Android code, we could find. Unfortunately, we must ask for your understanding that some of the code may not work with the used of you Android version. Over time we will be able to gather such information hopefully. You can support us in the comments or in the forum here.

A warning in advance: Not all of these codes you really want to try your self, because some of them delete all your data. open other codes you menus, the content itself beyond our knowledge. So if you do not exactly know what you are doing, then it really does not.
