Did you know that your smartphone had hidden menus?

Did you know that your smartphone had hidden menus?
Hidden menus and codes on cell phones are anything but new. Back in the days, even the old-school brick phones had these, allowing people who knew about them to access service options and software information. Today, a "secret" menu exists on most (if not all) popular smartphones, and to get to it, you just need to input the right code.

What code, you ask? Well, you've probably heard of *#06# which you type in your dialer, as if you were about to "call" it. When this particular code is entered, and it should work on any cell phone, the device's identity number (IMEI) is displayed. A smartphone's hidden menu can be accessed with a code that looks pretty similar to this one.

On iPhone, for example, you enter *3001#12345#* in the Phone app and then hit the call button to get to the field test menu. There's not much going on there, however, unless you're a technician. You can view SIM card information, details on the cell network's status, and all sorts of other cryptic numbers. It is interesting that signal strength in displayed in decibels while in this menu, not represented by circles.

Hidden menus and codes on Android phones may differ, depending on the device's make and model. This one, however, should work on most – *#*#4636#*#* (or *#*#INFO#*#*). It takes the user to a testing menu where network information is displayed, along with details on battery status and app activity. Be warned: don't change anything and don't press any buttons in this menu unless you know what they do! On a side note, this particular menu was used to "enable" 4G LTE in Canada on the Nexus 4.

And if you own a Nokia Lumia smartphone, try dialing ##634#. This will take you to an on-device diagnostics tool where the phone's hardware can be tested from. It will also let you see your phone's battery consumption in real time.

Sony's *#*#7378423#*#* or *#*#SERVICE#*#* will give you a screen for testing every component on your phone such as:
- Buttons
- Touch Screen
- Display (for seeing dead pixels)
- Notification LED, Flash LED
- Speaker, Earphone
- Microphones
- Cameras
- Sensors (Accelerometer, Gyro, Compass, Baro, etc)
- NFC, GPS, BT, WiFi
- Battery Health (with indicator for replacement and actual capacity uAh)

Samsung's *#0*# also shows a menu with better GUI but with less test... such as
- Screen's Primary Colors
- Vibration
- Dimming
- Touch
- Cameras
- Speaker
- Sensors

On my Lumia 710, after opening the hidden menu from the dialer, it appears on my list of installed apps. Does it do the same for Windows Phone 8/8.1?

On a side note, this particular menu was used to "enable" 4G LTE in Canada on the Nexus 4 (And on T-Mobile in the US)

There, fixed that for you!

I found the 4636 code and used it because AT&T didn't freaking let me switch between Edge, WCDMA, and LTE, in the normal settings.

While codes are fun, as the post points out, some of them give you the ability to mess up your phone. For Android, Network Info II (Alexander Schillings, donation-ware) will give you more information than I knew what to do with (although other PA readers will undoubtably understand it all).
