🟦 Section 1 — Understanding How Smart Remote Apps Work

Smart remote apps connect via:

✔ Wi-Fi (most common, fastest)

Device and phone must be on the same network.

✔ Bluetooth (backup for some TVs)

Used for short-range pairing.

✔ IR (older devices)

Requires a phone with an infrared blaster.

Most issues come from network visibility, not the app itself.

Step 2 — Connect Your Phone to the Correct Wi-Fi Network

Ensure your phone is on the same 2.4GHz or 5GHz network as your TV or projector.

Common mistake:
Users connect the TV to 2.4GHz but the phone to 5GHz guest Wi-Fi.

Step 3 — Enable Device Discovery

On your TV or projector, enable:

• “Allow mobile control”

• “Device discovery”

• “Network control”

• “ADB control” (for Android TV boxes)

Settings vary but are easy to find under:
Settings → Network → Device Control

Step 4 — Open the App and Scan for Devices

Most apps instantly detect:

• Android TV / Google TV

• Roku TV

• Fire TV

• Projectors (XGIMI, Dangbei, Xiaomi, Nebula)

• Smart TVs (Samsung / LG via Wi-Fi)

If scanning fails, see the troubleshooting section.

Step 5 — Pair the Device

Tap your device name → Confirm pairing code → Connected.

You now get:

• Navigation control

• Apps launcher

• Keyboard input

• Touchpad

• Volume & playback control

• Casting (depending on app)
