Your Android device holds a large amount of information about its hardware and system that an average user might find difficult to access. But if you know Android's secret codes, you can factory reset your device, find out its hidden camera information, instantly back up your precious data and much more.
Some 'secret' codes are Android system codes, and usually begin with an asterisk or a pound symbol/hashtag. These don't require you to be connected to a network to use them, since they're just for the Android system on your device. These codes are updated regularly as new versions of Android software are released, and some manufacturers have their own additional special codes.
The code entry procedure is very simple and only requires you to bring up your dialer keypad and enter the appropriate number sequence. It's important to note that some codes are carrier-specific, so they won't work on all devices.So if your phone doesn't respond to a code, don't dwell on it, just move on and find another one.
Warning! These codes should be used with caution. They can make your phone lose data, or render it unusable. There's a lot of incomprehensible tech jargon which pops up in the menus after entering some of these codes, which means that if you aren't 100 percent sure what you're doing, don't do it.
These codes are mostly universal, and should work on Android devices, no matter the manufacturer. There might still be carrier restrictions on certain codes though, so they're not all guaranteed to work.

USSD codes
These aren't the secret ones, but they're not so well known. USSD, or Unstructured Supplementary Service Data, codes connect to the phone's network once dialed to perform certain functions, like finding out how much credit you have left on your prepaid phone or how much data you've used this month. They change often, and the codes vary from carrier to carrier. Here are a few you can try for some of the major US carriers, along with links to more carrier-specific codes:
There's a good chance you'll never need to use most of these codes, but if you do, then now you know where to find them.
Are there any secret codes that you find yourself using all the time? Or are there any we haven't listed here that are really interesting? Let us know in the comments!
These codes are generic for Android - so for instance a Google device or other devices running the Stock version of Android. Whilst some will work on other devices running a manufacturer version of Android, it's a hit or a miss as to what works.
You can try searching for Samsung specific codes, though again it is not 100% certain that all of them will work. (some may be specific for the Galaxy range, or may change for different years).
You can download apps from the Google play store that aggregate these settings to a helpful UI.
Sophia, did you even test any of these codes on a phone before publishing, most of them are copied from one website to another ad nauseum and don't actually work... Does androidPit just publish anything as click bait without checking?
I tried one of these codes in 2015, it's 2018 now and I have only just arrived back in time again after the code allowed me to travel forward in time to 2023. Luckily I was able to enter the same code into my Trump z5s tablet and it worked fine. Treat these codes with caution.
Can someone PLEASE tell me the dialer code to remove the carrier picture that shows when you 1st boot the phone. There is one I found it once but am having a hard time finding it again.. It did work too i just need it again for my replacement phone now.
You're joking right? What a funny guy! Nobis, Ha! I didn't even see Samsung. There was HTC and Motorola. That's it. I've never even heard of nobis and you're looking for a hidden code for an obscure tablet hahahahahahahahahahahahahahahahahahahaha hhahahahahahahahahahahaha hhahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha .
I'm curious if doing a format would allow windows to be installed on a phone
Thanks for the informative article 😊.
nice useful article 👍
I tried the code for mac address in my phone dialer of Samsung a50, But it didn't give me mac address. I don't know how?

yes they do
These codes are specific to Stock Android, they may work on manufacturer altered versions of Android though it's not guaranteed.
