Smartphones today come with many features that can make life easier. But often, these features are hidden and go unnoticed by most users. Whether you have an iPhone, an Android, or a Samsung Galaxy, there are probably some useful tricks on your phone that you haven’t discovered yet. These hidden features can help you get more out of your device without having to download extra apps or learn complicated settings.

For iPhone users, one of the most overlooked features is called “Back Tap.” This function lets you set up shortcuts for tasks just by tapping the back of your phone. “It’s super helpful for things like turning on the flashlight or taking a screenshot,” says iOS expert John Doe. Instead of going through the settings or using multiple buttons, you can just tap the back of your phone to quickly access common functions. To activate Back Tap, go to Settings > Accessibility > Touch > Back Tap, and choose the actions you want to assign.

Another hidden iPhone feature is the ability to set custom vibrations for different contacts. This can be helpful if you want to know who’s calling or texting without even looking at your phone. To set this up, go to Settings > Sounds & Haptics > Ringtone > Vibration. You can then create a custom vibration pattern for specific people, so you’ll feel a unique vibration when they reach out to you.
