One of the biggest reasons why Apple fans enjoy their iPhones is the hidden features pre-installed to the devices. This can help users navigate quickly through the smartphone or enhance the user experience through utility tools.

It should be emphasized that sources like Starhub can list up to 17 hidden features in iPhone 7. However, for the sake of simplicity, this article will only discuss five of the most useful features installed. Hopefully, these tools can help Apple fans transform their smartphone from a connectivity device to a handy multi-purpose gadget.

Using iPhone as a Magnifying Glass

One simple but extremely helpful feature in iPhone is called the Magnifier. Note that this feature is separate from simply zooming in with a camera on a subject.

This app will let users read super tiny text in real-time. Admittedly, using the iPhone camera at close proximity could also bring out a crisp image rendering of the subject.

To use the feature, iPhone owners should open their search bar and type Magnifier. Note that this hidden app also has tools like brightness and other filters.

Default QR Scanner

For reference, most users usually download a third-party QR code scanner for their devices. However, be warned that these kinds of apps could charge for services or carry malicious codes on its program.

So to avoid the security threat, iPhone users can just take advantage of the QR scanner already installed in the device! This feature is called "Code Scanner" which can be activated by going into "Settings" and "Control Center." Be warned that this hidden app needs an internet connection to work.

Voicemail Transcription

The third hidden feature on this list is a handy tool for fans receiving a lot of voicemails. IPhones have the ability to automatically transcribe a voicemail, which means they can convert an audio message to text so users do not have to listen to the static noise on the other end.

Users can activate this feature by simply going to "Phone," then to "Voicemail," and finally opening the message. This should automatically show the message in the text version.

Control a Remote Printer with an iPhone

One popular feature that fans might have heard of is the AirPrint. This feature lets a user print a file to a remote printer without using cord connectors. The feature is handy, but it can be a bit tricky to set up.

According to USA Today, the printer and iPhone must be connected on the same Wi-Fi network. Then, the user will open the document, note, photo or file that they need to print. Click on the document settings and select the "Print" option. The iPhone will also provide a secret App Switcher that can monitor the printing progress in real time.

How to Check iPhone Cell Service

Lastly, users can check on the strength of their cell service through a feature activated by a secret code. For reference, the feature will measure the signal strength by decibels, with -40 being a strong signal and -120 as a "dead zone."

IPhone users can activate this feature by opening their "Phone" app and dialing: *3001#12345#*

After a few seconds, the iPhone should display the signal strength, which can help users find the best spot to search for a stronger connection.
