The iOS mobile operating system offers the average user a complete set of tools for comfortable interaction with all the capabilities of a smartphone. An interested user is often interested in the hidden functionality of the entire ecosystem in order to gain access to non-obvious features. If you think that iOS 8 (9) has been studied inside and out, you are mistaken.
Display signal strength in numbers (instead of dots)
By default, any modern smartphone displays information about the network signal level in the form of a visual indicator: bars or dots. To enable the cellular network net-monitoring function in the digital equivalent on the iPhone, a secret code is provided.
- 1. Open the dialer (phone dialing menu) and dial the following combination: 2. Press the call key. The Field Test menu opens.
- 3. ATTENTION!It is not recommended to change anything in this menu.
The network signal strength is now displayed in numerical equivalent. A single tap will switch digital mode to dots mode.
4. Press the power key until the slider appears. 5. Press and hold the Home key for 10 seconds until you return to the Springboard.
The function is activated. A single tap on the network signal level will switch the mode to digital/graphic.
How to find out the cellular signal strength on an iPhone
The cellular signal level in the form of strange sticks can be changed to a more convenient and simpler variation. To do this, through the iPhone engineering menu you need to dial the code *3001#12345# and press the call button. A text window appears in front of the user. Next you need to take the following steps:
- Press and hold the power button. The user should see the message “Enable”.
- The power button should be turned off and then press "Home".
- Hold the home button until the device switches to the desktop.
How to check an iPhone for wiretapping - codes and combinations
Upon completion of this procedure, the signal level will be displayed in the form of numbers. The general meaning is as follows:
- 40 – excellent reception;
- from 50 to 80 – stable;
- from 90 to 120 – bad.
- 140 – no signal.
Important! You can use this command on all Apple mobile phones with the exception of iPhone 7 and 7 Pluse.

Reducing brightness “below possible”
A bright display with a good level of color rendering is one of the main advantages of Apple smartphones. Nevertheless, there are a number of users for whom even the minimum brightness value in complete darkness causes a feeling of discomfort. Using the following setting you can reduce the brightness level to an absolute minimum.
- 1. Open Settings – General – Accessibility – Zoom. 2. Turn on the Show Controller .
- 3. Return to the previous menu and scroll to Keyboard shortcuts . Turn on the only item Magnification (check the box opposite).
4. Press the Home key three times in a row . Tap on the joystick controller that appears. Set the magnification slider to minimum . Open Select filter .
- 5. Set the Low Light . Click Hide Controller .
Settings are complete. The screen has become significantly darker, and the usual brightness scale allows you to lower the level to the minimum level. To turn off the dim lights, simply press the Home key three times.
Call barring
Call barring prevents all outgoing calls unless you disable this feature. Since this option is not available in iPhone phone settings, you can use the following codes to use the call barring feature.
- Code to check call barring status: *#33#
- Code to enable call barring: * 33 * PIN #
- Code to disable call barring: #33 * PIN #
Note. If you set a SIM PIN in iPhone Settings → Phone or for some carriers in iPhone Settings → Mobile Data → SIM PIN, enter that PIN in the above codes. If you have not set a SIM card PIN, you can enter any arbitrary number. Like *33*9#
Quickly turn off the flashlight
They say that flashing your iPhone in a dark alley is a bad omen. This is why the quick turn off function of the built-in flashlight can be useful.
To turn on the flashlight directly from the lock screen, just swipe up from the bottom and tap on the corresponding icon. When using it at night, as a rule, we block the device screen, leaving the flashlight on (the bright smartphone screen is blinding). To quickly turn off the flashlight, just:
- 1. Press the Home or Power key. 2. From the lock screen, hold down the Camera icon and pull it up to a level just above half the screen , and then release.
The flashlight will be turned off.
5. Forward incoming calls to another number.
Using this, you can forward an incoming call to another number. This feature varies by carrier and may be paid or free depending on your cellular service.
- Code to check call forwarding status: *#21#
- Code to enable call forwarding: * 21phonenumber #
- Code to disable call forwarding: * 21 #
If the shortcodes above don't work for you, check out our separate guide to forwarding calls on iPhone. We've listed the exact steps for most US carriers.
Removing folder names
Each application has its own unique icon, not only for aesthetic purposes, but also so that the user can quickly open a specific program using visual and associative memory. However, every app in iOS has a signature name. For a group of applications contained in a folder, the need for such a signature does not always arise. You can disable folder names as follows:
- 1. Download any application in the App Store from the Food and Drinks category. 2. Drag the icon that appears to the application that you want to add to the folder, thus organizing a new directory. 3. Please note that the newly created folder will not be assigned any name.
- 4. Press the Home . 5. Add the required applications to the created “unnamed folder”, and you can delete the installed “food” one.
The created folder will not contain a name.
Learn about mobile data usage.
Nowadays, almost all telecom operators around the world have apps that help you keep track of your data limit. However, if you wish, you can use shortcodes to check your internet balance and more. Here are the codes for several popular US carriers.
- AT&T: *3282#
- Verizon: #3282
- T-mobile: #932#
You can Google your carrier code. For example, 'code to find out airtel internet balance.'
Disabling tabs in Apple Music
The emergence of the Apple Music service has significantly expanded the horizons of preferences for music lovers. Millions of songs are now available without the need to download. Disadvantages of the service include dramatic changes in the Music application. A number of additional tabs somewhat complicate interaction with the usual program. You can disable the “unnecessary” (provided that the service is not of interest to you) using a few simple steps:
- 1. Open Settings – Music. 2. Turn off the Show Apple Music slider . 3. Open Settings – General – Restrictions. Enter the set password. 4. Disable the item Connect to Apple Music .
This is what the Music application looked like before the above steps were completed: And this is what it looks like after: The application has acquired its usual appearance. To enable Apple Music, simply perform all of the above steps in reverse order.
