Expand Your Fleet: Using NX Control on Samsung & Non-NX Branded Android Hardware 📱✨

Want to run NX Restaurant POS on standard Android hardware—like a Samsung tablet—while keeping the same powerful device management you get on NX-branded terminals? You can!

With NX Control, you can easily manage third-party Android tablets to lock down kiosk mode, deploy silent app updates, and give your support team remote access—all while giving your restaurant staff a flexible, portable POS setup 🚀!

This guide walks you through the requirements, step-by-step QR code provisioning, feature compatibility, and troubleshooting tips for non-Nexus hardware.

What is Supported? 🤔

Yes, NX Control can manage most standard Android devices! You get the same core management capabilities as native NX hardware, including:

🔒 App Kiosk Lock-Down: Prevents staff or guests from leaving the NX Restaurant app.
🔄 Automatic Background Updates: App and controller updates install silently.
🛠️ Remote Diagnostics: Health tracking, reboots, and status checks from support.

Good to Know:

Because NX Control isn't built into the factory system software on non-NX devices, a few advanced features (like remote screen sharing prompts or USB card reader permissions) work slightly differently.

Prerequisites Before Setup 📋

Before onboarding a Samsung or third-party Android tablet, ensure you have:

📱 Android Version: Running Android 8.0 or later (Android 12 or higher recommended).
🔄 Factory-Fresh or Reset Device: NX Control must be installed during initial first-time device setup before any Google or Samsung accounts are added.
📶 Active Network: A Wi-Fi network or mobile data connection with internet access.
📷 Provisioning QR Code: A setup QR code supplied by your NX Support representative.

Warning: Factory Reset Required!

Adding NX Control as a device manager requires starting from a factory-reset state. All existing data on the device will be erased.

Step-by-Step: Provisioning a Device Using a QR Code 📲

Step 1: Perform a Factory Reset:

If the device has already been set up, navigate to Settings ➔ General management ➔ Reset ➔ Factory data reset. (Menu names may vary slightly by brand).

Step 2: Open the QR Code Scanner:

Power on the device and select your language on the initial "Welcome" screen.
Stop here—do not tap Start or sign in!

Tap the exact same spot on the Welcome screen repeatedly until the camera scanner opens:

Standard Android devices usually require 6 taps.
Samsung tablets may require 10 to 11 taps.

Step 3: Connect to Wi-Fi:

Connect to a Wi-Fi network that has active internet access.

Step 4: Scan Your NX Provisioning QR Code:

Hold your NX provisioning QR code steady in front of the camera.

Step 5: Complete Automatic Installation:

Wait a few minutes while Android automatically downloads and installs NX Control. Accept any on-screen system prompts that appear.

Step 6: Registration & Launch:

NX Control will launch automatically, register the hardware with your venue, and download the NX Restaurant POS app! Within a few minutes, the terminal will appear in your NX Portal.

What Works vs. What Changes ⚖️

Because third-party manufacturers (like Samsung) customize Android differently, here is how features compare to native Touch Dynamic Nexus hardware:

Works the Same as Nexus Devices 🟢

Feature	Performance & Notes 💡
Kiosk Mode Lock-Down	Fully supported—keeps device locked to NX Restaurant.
Silent App Updates	Fully supported without user prompts.
System Updates	NX Control updates automatically in the background.
Remote Commands & Reboots	Fully supported by NX Support.
Printer & App Allow-Lists	Fully supported.

Works Differently or Varies by Device 🟡

Feature ⚙️	What to Expect on Non-Nexus Hardware 🔍
Remote Screen Viewing	A security prompt pops up on screen each time a session starts. Staff at the tablet must tap "Start now" before support can view the screen. (Nexus hardware requires no prompt).
Remote Touch Control	Requires Accessibility permissions. If the device blocks automatic setup, staff may need to enable it once under Settings ➔ Accessibility.
USB Card Reader Access	The tablet may ask to approve USB access when first plugging in a reader. Always select "Always" or check "Use by default".
Remote Card Reader Resets	Varies by hardware manufacturer. If a reader stops responding, rebooting the tablet remains the most reliable fix.
Screen Orientation	If NX Control cannot force screen rotation, adjust orientation manually under the tablet's system display settings.

Samsung-Specific Optimization Tips 💡

🔋 Prevent Battery Sleeping: Samsung tablets aggressive battery-savers may put background apps to sleep. If a tablet goes offline, open Settings ➔ Battery ➔ Background usage limits and make sure NX Control is not listed under "Sleeping apps" or "Deep sleeping apps".

Frequently Asked Questions & Troubleshooting ❓

Provisioning Troubleshooting 🛠️

Problem 💡	Recommended Fix 🛠️
Tapping the screen doesn't open the QR camera	Keep tapping in the exact same spot! Samsung devices often require up to 11 quick taps. Ensure you are on the very first "Welcome" language selection screen.
"Can't set up device" or download error	Verify that your Wi-Fi network has active internet and isn't blocking downloads. Try connecting to a mobile phone hotspot.
