Video Tutorial: Screen Mirror From Phone to Onn TV
Step 1: Set Up Your Onn TV Box/Stick
First, make your Onn TV easy for your phone to find. Both devices must be on the same Wi-Fi network, otherwise your phone won’t detect the TV.
Make sure your Onn TV and Android phone are connected to the same Wi-Fi network.

Its name changes by brand, so look for Smart View (Samsung), Screen Cast, or Wireless projection. If you don’t see it, add it from the edit option in quick settings.
Swipe down from the top of the screen to open the quick settings panel and select the Cast option.
Swipe down for quick settings > “Cast”
When your Onn TV appears in the list, tap it and confirm the connection if prompted.

Tips for Smoother Mirroring
Once connected, you can scroll apps, open photos, play videos, give presentations, or even play mobile games on the bigger display. To get the best result:
- Rotate your phone sideways.
- Use full-screen mode.
- Use 5 GHz Wi-Fi.
- Stay close to the router, and keep both devices in the same room when you can.
- For movies and shows, use the Cast icon inside the app instead of full mirroring for a better experience.
Phone Not Finding Your Onn TV? Try These Fixes
If your phone can’t see your Onn TV, or the picture is choppy, work through these common causes and fixes.
| Problem | Fix |
|---|---|
| 🔍 Onn TV doesn’t appear | Check both devices are on the same Wi-Fi, and that Cast is set to Always. |
| 🌐 Router blocks it | Turn off any guest network or “client isolation” setting on your router. |
| 🐢 Laggy or choppy picture | Move closer to the router, switch to 5 GHz, and close other apps on your phone. |
| 🔒 VPN running on your phone | Turn the VPN off while mirroring, since it can hide the TV on your network. |
| 🔄 Still not working | Restart your Onn TV, your phone, and your router, then try again. |
