Since the APK is installed manually, Android requires permission to install apps from outside the Play Store.

Depending on your Android version:

Android 8.0+

2. Go to Apps & notifications
3. Tap Special app access
4. Tap Install unknown apps
5. Choose the app you will use to install the APK (Chrome, Files, USB file manager)

2. Tap Security
3. Enable Unknown sources

Step 1 — Transfer the APK file

You can install the APK using any of the following methods:

• Push via ADB (advanced users)

Step 2 — Install the APK

1. Open the APK file using your file manager

You can install the Screenflex APK from your computer using ADB (Android Debug Bridge).

ADB works via USB cable or wirelessly over Wi-Fi.

A. Install APK via USB (Most Reliable Method)

Step 1 — Enable Developer Mode

On the Android device:

• Open Settings
• Go to About phone / tablet / device
• Tap Build number 7 times
• Enter your PIN if asked

  You’ll see: “You are now a developer!”

Step 2 — Enable USB Debugging

• Go to: Settings → Developer Options
• Enable: USB debugging
• Connect the device to your computer via USB.

Step 3 — Verify ADB Connection

On your computer, run:

adb devices

If you see the device listed, you're ready.

Step 4 — Install the APK

adb install screenflex.apk

If the app already exists and you want to overwrite it:

adb install -r screenflex.apk

B. Install APK via Wi-Fi (When USB Is Not Available)

Wi-Fi installation is ideal for kiosk screens, wall-mounted devices, or Android boxes where USB ports are inaccessible.

Step 1 — Enable Developer Mode

On the Android device:

• Open Settings
• Go to About phone / tablet / device
• Tap Build number 7 times
• Enter your PIN if asked

  You’ll see: “You are now a developer!”

Step 2 — Enable Wireless Debugging

• Go to: Settings → Developer Options
• Enable: Wireless debugging
• A screen will show a pairing code, an IP address and a port

Step 3 — Pair the Device

On your computer:

adb pair DEVICE_IP:PORT

Enter the code displayed on the device.

Step 4 — Connect

adb connect DEVICE_IP:PORT

Step 5 — Install the APK

adb install screenflex.apk

If the app already exists and you want to overwrite it:

adb install -r screenflex.apk

When you launch the app for the first time, the player will request several permissions.

• Storage Access: To cache media, download assets, and play offline content.
• Network Access: Allows content updates, reporting status, syncing schedules.

Tap Allow on all required permissions to guarantee stable operation.

Step 1 — Generate the Code

1. Log in to your Screenflex Dashboard.
2. Navigate to Screens → Add Screen.
3. Fill in the form.
4. A 6-digit pairing code will be generated automatically.

Step 2 — Enter the Code on the Android Device

1. Open the Screenflex app on your Android device.
2. Enter the 6-digit code provided by the dashboard.

   (Or enter the Screen Slug)

3. After a few seconds, the device will:
   • Link to your account
   • Sync the assigned playlists
   • Begin showing content automatically

This linking method ensures that only authorized users can register new screens.

App Pinning ensures no one can exit the Screenflex app accidentally. This is crucial for public-facing screens.

Android offers built-in App Pinning that locks the device to a single app.

How to Enable App Pinning (on most Android devices)

Step 1 — Enable App Pinning in System Settings

On the Android device:

1. Open Settings
2. Go to Security and privacy
3. Tap More privacy settings
4. Tap Allow apps to be pinned
5. Turn on App Pinning
6. Enable Lock phone after unpinning (very important for signage)

Step 2 — Pin the Screenflex App

1. Open Screenflex app
2. Press the Recent button. Or if you are using gestures, swipe up from the bottom of the screen and hold
3. Locate the Screenflex window
4. Tap the app icon at the top
5. Choose Pin this app

Your device is now locked to Screenflex.

Step 3 — How to Exit App Pinning

To exit (only if needed):

• On most devices:

  Hold both Back + Recent Apps buttons together

• If using gesture navigation:

  Swipe up and hold,then enter the device PIN/passcode.

This prevents staff, customers, or users from leaving the app.

Developer Mode allows you to access the Stay Awake option, which prevents the device from turning off the screen while charging — essential for stable digital signage operation.

Step 1 — Enable Developer Mode on Android

On the Android device:

1. Open Settings
2. Scroll down and tap About phone (or About tablet / About device, depending on the model)
3. Scroll until you find Build number
4. Tap Build number 7 times
5. Enter your device PIN or password when asked
6. You will see a confirmation message: “You are now a developer!”

Developer Options are now unlocked.

Step 2 — Enable “Stay Awake” (Prevents the screen from turning off)

1. Go to Settings
2. Tap System (or Additional settings, depending on device)
3. Tap Developer options
4. Scroll down until you find: Stay awake — Screen will never sleep while charging
5. Toggle Stay awake ON
