Android Secret Codes on iPhone: *#*#4636#*#*, *#0*# and What to Use Instead

If you have switched from Android, you may know a handful of codes that open hidden menus: phone info, battery stats, a screen test. Dial them on an iPhone and nothing happens. That is not because Apple has hidden them better. iOS simply does not have those menus. Here is what each popular Android code does and where to find the same information on an iPhone.

I build Secret Codes: IMEI & Carrier, a free iPhone app with 317 verified dial codes, and the screenshots in this guide come from it. If you would rather tap than memorise codes, get Secret Codes on the App Store.

Why don't Android codes work on iPhone?

There are three kinds of phone codes, and only two of them are portable:

• GSM standard codes such as *#06# (IMEI) and the call forwarding family. They are defined by 3GPP and handled by the phone or network the same way everywhere. These work on iPhone.
• Carrier codes, such as balance checks, handled by your network. These work on iPhone if your carrier supports them.
• Manufacturer codes such as *#*#4636#*#* or *#0*#. These open menus built into Android or Samsung's software. iOS has no such menus, so none of them work on iPhone.

The single Apple code in the last group is *3001#12345#*, which opens Field Test.

Android codes and their iPhone equivalents

Android code	What it does on Android	iPhone equivalent
*#*#4636#*#*	Testing menu: phone info, signal, usage	Field Test (*3001#12345#*) for signal; Settings > General > About for phone info
*#0*#	Samsung hardware test: screen, touch, speaker, sensors	A diagnostic app such as Secret Codes, or Apple Support diagnostics
*#0228#	Samsung battery status	Settings > Battery > Battery Health
*#1234#	Samsung firmware version	Settings > General > About > iOS Version
*#*#232338#*#*	Wi-Fi MAC address	Settings > General > About > Wi-Fi Address
*#*#2664#*#*	Touch screen test	The touch test in a diagnostic app
*#7353#	Samsung quick test menu	A diagnostic app, or Apple Support diagnostics
*#*#7780#*#*	Factory reset on some Android phones	Settings > General > Transfer or Reset iPhone (only if you mean it)

Codes that work on both Android and iPhone include *#06# for IMEI (see how to check your IMEI), *#21# for call forwarding status and *#43# for call waiting.

How do I test iPhone hardware without a code?

1. Battery: Settings > Battery > Battery Health shows maximum capacity and whether the battery needs service.
2. Parts history: on recent iPhones, Settings > General > About shows Parts and Service History if a part has been replaced.
3. Full hardware check: a diagnostic app can test the display, touch, speakers, microphone, cameras, sensors and Face ID in a few minutes.
4. Apple diagnostics: Apple Support can run official diagnostics on your iPhone when you contact them or visit a store.

Is it safe to try Android codes on an iPhone?

Usually nothing happens, and most of them are simply rejected. The risk is with codes someone sends you. A code that starts with **21*, **61* or *72 followed by a number is not a test code: it forwards your calls. If a message tells you to dial a "secret code" to fix your phone or claim a prize, do not. Read what *#21# and **21* mean to recognise the scam.

Which iPhone codes do work?

The short list is *#06# (IMEI), *3001#12345#* (Field Test), the call forwarding, call waiting and caller ID codes, and your carrier's own codes. I keep the full verified list in iPhone secret codes that actually work, and explain Field Test readings in iPhone Field Test mode.

How Secret Codes helps

• 317 verified iPhone codes, each checked against a carrier, Apple or the 3GPP standard. Android-only and retired codes are left out.
• Plain-English explanations of what every code does before you dial it.
• Open in Phone puts the code in Apple's dialler. Nothing is ever dialled for you.
• Built around your carrier: each code says whether your network publishes it.
• A full diagnostic suite for battery, storage, Wi-Fi, cellular, display, touch, cameras, sensors and Face ID.
• IMEI in one tap with Siri, Spotlight, Shortcuts and a Home Screen quick action.
• Free, with nothing locked: no paid tier and no subscription.
