Your Samsung Phone’s Back Panel Is Smarter Than You Think: 3 Hidden Features Unlocked!

When you look at the back of your Samsung Galaxy smartphone, you might think it's just a glossy or matte surface that completes the aesthetic design. But did you know that the back panel of your Galaxy device holds some incredible, intelligent features that go beyond just good looks?

Samsung Phone Back Panel Hidden Features and Tricks

Yes, Samsung has infused functionality into the rear of your device, turning it into a productivity powerhouse. With the right tools and knowledge, you can transform your phone’s back into a multi-tasking touch zone, a wireless power hub, and a tap-and-pay wallet.

In this blog, we’ll explore three powerful tricks your Samsung phone’s back panel can do:

1. Double/Triple Tap Gestures via RegiStar

2. Wireless Charging via Wireless PowerShare

3. Contactless Payments via NFC Tap-to-Pay

Let’s dive in and learn how to unlock these brilliant features and start using your Galaxy device like a pro.

1. RegiStar: Add Back Tap Gestures on Your Galaxy Phone

One of the most underrated features Samsung users often miss is the ability to perform tasks with simple taps on the back of the phone. While Apple natively supports Back Tap on iPhones, Samsung doesn’t offer this out of the box—but there’s a trick.

Enter: RegiStar from Good Lock

Samsung’s RegiStar is a plugin available under the Good Lock suite (downloadable from Galaxy Store) that enables back tap gestures for supported Galaxy devices. And the best part? It’s absolutely free.

How to Enable Back Tap Gestures on Samsung:

1. Download Good Lock from the Galaxy Store.

2. Open the app and search for RegiStar under the "Life Up" category.

3. Tap to install RegiStar.

4. Launch RegiStar and head to the Back Tap Action section.

5. Enable Double Tap and Triple Tap options.

Customization Options:

You can assign a variety of tasks to each tap. For example:

• Double Tap:

  • Take Screenshot

  • Open Notification Panel

  • Launch Samsung Wallet (Scan QR)

  • Activate Google Gemini AI

• Triple Tap:

  • Show Recent Apps

  • Trigger Back Gesture

  • Launch any installed app

  • Start Pop-Up Window of Current App

Many users (including myself) find it handy to assign quick payment actions to Double Tap and AI assistant to Triple Tap.

📱 Pro Tip: Assign Samsung Wallet’s “Scan any QR” to Double Tap for instant payments and Gemini to Triple Tap for quick AI assistance.

This is a game-changer in daily usability. Imagine just tapping the back of your phone twice to instantly scan a QR code – smooth and efficient!

2. Wireless PowerShare: Reverse Charging with the Back Panel

Samsung’s Wireless PowerShare turns your Galaxy device into a wireless charger for other compatible gadgets. Yes, you heard it right—your phone can charge other devices!

This feature is available on Samsung Galaxy phones that support wireless charging, including most of the Galaxy S series, Z Fold/Flip series, and Note series.

How to Use Wireless PowerShare:

1. Open Settings > Battery and Device Care > Battery.

2. Tap Wireless PowerShare and turn it ON.

3. Place the other device (like Galaxy Buds, Watch, or even another phone) back to back with your Samsung phone.

4. Make sure the receiving device supports Qi wireless charging.

That’s it! Charging begins automatically when the alignment is correct.

Compatible Devices:

• Galaxy Buds / Buds2 / Buds Live / Buds Pro

• Galaxy Watch series (Watch 4/5/6 and above)

• Other Qi-compatible smartphones (including iPhones)

• Accessories like ring cases with wireless charging support

📦 Note: The power output is not very high, so it’s best used for topping up accessories or emergency sharing between phones.

Use Cases:

• Your friend’s phone battery is dying? Give them a quick boost.

• Galaxy Buds case out of juice? Just place it on your phone’s back.

• Need to charge your Galaxy Watch while traveling? No need to carry its dock.

It’s incredibly convenient and showcases how Samsung has smartly utilized the back panel of its devices.

3. NFC Tap to Pay: Turn the Back Panel into a Wallet

Near Field Communication (NFC) is another powerful feature hidden in the back panel of your Samsung phone. It enables contactless payments, file transfers, digital keys, and more.

Among its various uses, the most common and powerful one is NFC Tap-to-Pay.

Samsung Wallet + NFC = Easy Payments

Samsung has been equipping Galaxy phones with NFC for several years now. With the help of Samsung Wallet, you can pay at stores simply by unlocking your phone and tapping the back panel against a payment terminal.

How to Set Up Tap and Pay:

1. Open Samsung Wallet app.

2. Add your preferred debit/credit card.

3. Enable Tap & Pay in the settings.

4. Choose Samsung Wallet as the default payment app.

5. To pay, unlock your phone, open Samsung Wallet, and tap the back against the payment terminal.

⚙️ Security First: All payments require biometric authentication, so it’s extremely secure. No card data is stored directly; instead, tokens are used for secure transactions.

Supported Platforms:

Samsung Wallet works across many countries and is compatible with Visa, Mastercard, and local payment services depending on your region.

You can also use NFC for:

• Transferring files via Android Beam

• Smart tags and digital locks

• Transportation passes

• Access cards (in supported locations)

Bonus Tip: Decorate and Protect Your Back Panel with Function

While not software-based, your phone’s back panel can also be customized with utility-focused accessories:

Skins and Wraps:

• Available online in matte, glossy, carbon fiber, or even leather textures

• Add grip, personalization, and scratch protection

Functional Phone Cases:

• Kickstand cases for media viewing

• Mirror-like covers that double as a reflective surface

• Magsafe-style cases with magnetic charging support

• Cardholder cases to keep your essentials handy

These accessories further improve the usability of your phone's back without compromising the aesthetics or tech features.

Conclusion: Your Galaxy’s Back Panel Is a Power Tool

Gone are the days when the back of your smartphone was just for branding and camera placement. Today, Samsung has turned it into a multi-functional panel that can:

✔️ Trigger smart actions via back tap gestures with RegiStar
✔️ Charge other devices wirelessly using Wireless PowerShare
✔️ Make secure payments through NFC Tap and Pay with Samsung Wallet

Whether you’re making a quick payment, helping a friend charge their earbuds, or launching your favorite app with a tap, the back of your Samsung phone is doing more than you ever imagined.
