10 Hidden iPhone Features You Might Not Know About: iOS Secrets

There are many hidden features in iOS that you might not know about. In this blog post, we will discuss 10 of them. Some of these features include the ability to quick delete numbers in the Calculator app, last number speed dial, and scanning documents in the Notes app. We will also discuss how to improve your Touch ID experience and return to top in any application. Keep reading to learn more!

Quick deletion of numbers in the “Calculator”

Sometimes you need to remove the last number or operation in the calculator, but there is no such button. What can I do? Just swipe to the left or right on any digit! On older versions of iOS (before 11), it will delete one symbol at a time; on newer firmware – immediately everything that was added after pressing C. This feature works both in portrait and landscape modes, so if something went wrong with how many digits were pressed, just use your fingers again!

Last Number Speed Dial

This feature allows users who have Apple Watch paired with iPhone XS / XR/11 Pro and later models to quickly call back their latest incoming caller without having to unlock their device first. The only thing needed for this functionality is that the last number dialed from your phone must be in Contacts. If you want to know how to spy on an iPhone, then you should read on.

Fast burst shooting

There is a hidden feature on iPhone called “Burst Mode” which allows you to take multiple photos at once by holding down the shutter button while pressing it like usual (or using Volume Up button if there are no physical buttons). The only thing needed for this functionality is that last number dialed from your phone must be in contacts! And how do we know how many times has been pressed? By looking at how many images appear when we open our Photos app after taking them – another way would be using Siri voice commands such as, “Take ten pictures with flash” or even “take one hundred photos without flash” but it will take some time to process all the images.

Instant currency conversion

iPhone also offers a built-in calculator that can convert between different currencies, which is great when you’re traveling or need to make a quick calculation. To use this feature, just launch the Calculator app and tap on the $ key to bring up the currency converter. From there, you can select the desired currency and enter the amount you want to convert. The Calculator will automatically display the result in your selected currency.

Improve your Touch ID experience

If you have an iPhone with Touch ID, there are a few things you can do to improve your experience. First, try calibrating your fingerprint sensor by going to Settings > General > Accessibility > Fingerprints & Passcodes and tapping on “Fingerprint Sensor Calibration.” Next, make sure you’re using a strong password to protect your device. Finally, try disabling the Attention Aware feature by going to Settings > Face ID & Passcode (or Touch ID & Passcode) and turning off “Attention Aware.”

Scanning Documents in the Notes App

The Notes app provides a great way to scan documents directly into your iPhone. Just launch the Notes app and tap on the + icon at the bottom of the screen. From there, select “Scan Documents” and use your iPhone’s camera to scan the document. The Notes app will automatically detect any text in the document and allow you to edit it as needed.

Opening an accidentally closed tab in Safari

If you’ve ever accidentally closed a tab in Safari, you’ll be happy to know that there’s a hidden feature that can help you reopen it. Just press and hold the + icon at the bottom of the screen and select “Reopen Last Closed Tab.” Safari will automatically open the last tab that was closed.

Filters in the Photos app

The Photos app on iPhone includes a number of filters that you can use to improve your photos. To access them, just launch the Photos app and tap on the Filter button at the bottom of the screen. From there, you can select from a variety of filters to apply to your photo.

Accelerated character set

iPhone supports an accelerated character set which provides a faster way to type certain characters. To access it, just go to Settings > General > Keyboard and turn on “Accelerated.” When enabled, you’ll be able to type the following characters faster: !”#$%&'()*+,./:;=?@[\]^_`{|}~.

Return to top in any application

There’s a hidden gesture that allows you to quickly return to the top of any application. Just swipe down from the status bar at the top of your screen (the area where you see the time, battery life, and signal strength) and the app will scroll up until you reach the top. This is a great way to quickly navigate through long apps like Messages or Facebook.


These are just a few of the hidden features in iOS that you might not know about. Be sure to explore all of the different settings and options available to you and see what else you can discover. iPhone is packed with great features and possibilities, so have fun playing around with it!
