Auraz TechHow to Cast Your Android Phone to a TV (3 Easy Ways)
Whether it's sharing holiday photos with family, presenting slides without a laptop, or just watching phone videos on a screen that doesn't require squinting, mirroring your Android phone to a TV is one of those features everyone should know. There are three reliable ways to do it — wireless via Chromecast, wireless via your TV's built-in mirroring, or a simple wired cable. Pick the one that matches your TV.
Before You Start: What Does Your TV Support?
- Chromecast built-in / Google TV / Android TV: most Sony, TCL, Hisense, Philips, and Chromecast-dongle setups. Look for a Chromecast or Google TV logo.
- Samsung Smart TVs (Tizen): support screen mirroring via Smart View / SmartThings, plus Chromecast in many apps.
- LG (webOS), Fire TV, Roku: support Miracast or their own mirroring protocols; many also work with Chromecast from within apps.
- "Dumb" TV with HDMI port: the wired method works with literally any TV.
Method 1: Cast with Chromecast Built-In (Easiest Wireless)
If your TV has Chromecast built-in (or you have a Chromecast dongle plugged in), this is the smoothest option.
Casting a single app (YouTube, Netflix, etc.)
- Connect your phone and TV/Chromecast to the same Wi-Fi network — this is the #1 reason casting fails.
- Open the app and tap the Cast icon (rectangle with Wi-Fi waves, usually top-right).
- Select your TV from the device list. The video plays on the TV while your phone becomes a remote.
Mirroring your entire screen
- Open the Google Home app (install it free from the Play Store if needed).
- Tap your Chromecast / TV device, then tap Cast my screen > Cast screen.
- Everything on your phone — apps, photos, games — now mirrors to the TV. Tap Stop mirroring in the notification shade when done.
Alternative shortcut: swipe down twice for Quick Settings and look for Screen Cast — on many phones it jumps straight to device selection.
Method 2: Wireless Mirroring Without Chromecast
Samsung phones to Samsung TVs: Smart View
- Swipe down twice to open Quick Settings and tap Smart View.
- Select your Samsung TV. Accept the connection prompt on the TV if asked.
- For the best experience, also install SmartThings — it adds remote-control features and easier reconnection.
Miracast (LG, some Sony, Windows-friendly TVs)
- On the TV, open its Screen Mirroring / Miracast input (often under Source or Network settings).
- On the phone: Settings > Connected devices > Connection preferences > Cast, tap the three-dot menu, and enable Wireless display.
- Your TV should appear — tap it to connect.
Note: Google has de-emphasized Miracast on Pixels in favor of Chromecast, so this works best on Samsung/Xiaomi/Oppo phones.
Method 3: Wired HDMI (Most Reliable, Zero Lag)
For gaming, presentations, or TVs without any smart features, a cable beats wireless every time — no Wi-Fi dependency, no latency, no compression artifacts.
- What to buy: a USB-C to HDMI adapter (around $15–25). Check that your phone supports video output over USB-C — most Samsung Galaxy S/Note, OnePlus, and Xiaomi flagships do; many budget phones and Pixels (before Pixel 8) do not. Search "[your phone model] USB-C HDMI alt mode" to confirm.
- How to use: plug the adapter into your phone, connect an HDMI cable to the TV, switch the TV to that HDMI input — the screen mirrors instantly. No apps, no settings.
- Samsung DeX bonus: on supported Galaxy phones, the same cable launches DeX — a full desktop interface on your TV. Transformative for presentations.
Fixing Common Casting Problems
- TV doesn't appear in the device list: confirm both devices are on the same Wi-Fi network (not one on 5 GHz and the other on 2.4 GHz with client isolation). Restart the TV/Chromecast and the phone.
- Choppy or laggy mirroring: move closer to the router, switch the router to a less congested channel, or drop the phone's screen resolution temporarily. Mirroring full games wirelessly will always have some latency — use the cable for gaming.
- No sound on TV: raise the TV volume (phone volume controls the cast stream separately); in full-screen mirroring, check the phone isn't on silent/vibrate with media volume at zero.
- "Couldn't connect" errors: disable VPN on the phone — VPNs frequently break local device discovery.
- Netflix/Disney+ won't cast but YouTube does: some apps block casting from rooted phones or outdated app versions — update the app and Google Play Services.
Which Method Should You Choose?
- Everyday videos and photos: Chromecast built-in (Method 1) — simplest.
- Samsung household: Smart View (Method 2).
- Gaming, presentations, or zero-lag needs: USB-C to HDMI cable (Method 3).
- Old non-smart TV: a $30 Chromecast dongle upgrades any HDMI TV to Method 1 permanently.
Use Your Phone as a TV Remote
Once you're casting regularly, take the next step and retire the TV remote:
- Google TV app: Google's free Google TV app includes a full remote — D-pad, volume, power, and keyboard input — for any Google TV, Android TV, or Chromecast. Tap the remote icon (bottom right) and pair with the code shown on your TV.
- Manufacturer apps: Samsung's SmartThings, LG's ThinQ, and Roku's app all offer remotes with extra tricks like private listening (TV audio through your phone's earbuds — perfect for late-night watching).
- Why it's better: typing passwords and search queries on a phone keyboard beats pecking at an on-screen keyboard with arrow keys every single time. Once you try searching YouTube by typing on your phone, you'll never go back.
Pair the remote app before you lose the physical remote — most pair via a code displayed on the TV, which you obviously need a working remote (or the TV's physical buttons) to reach.
Chromecast vs. Miracast vs. DLNA: What's Actually Happening
"Casting" covers three different technologies, and knowing which you're using explains most quirks:
- Chromecast (Google Cast): your phone tells the TV what to play, then the TV streams it directly from the internet. Your phone is just a remote — you can take calls or even leave the house without interrupting playback. Lowest battery drain, best quality. This is what the Cast button in YouTube/Netflix uses.
- Miracast (Smart View / Wireless Display): mirrors your phone's actual screen pixel-for-pixel over Wi-Fi Direct. Everything shows — including notifications — and your phone's battery drains the whole time. Quality depends on signal strength. This is what Smart View and "Wireless display" options use.
- DLNA: streams media files from your phone's storage to the TV over the home network. Good for playing downloaded videos and your own media library without internet.
Which to use when: streaming apps → Chromecast; showing your screen (presentations, apps without cast support) → Miracast; playing local files → DLNA or just cast from Google Photos/Files. If your TV supports all three, you never need a cable.
FAQ
Do I need Wi-Fi to cast my screen?
For wireless methods, yes — phone and TV must share a network. The wired HDMI method needs no Wi-Fi at all.
Will casting drain my battery quickly?
Screen mirroring is moderately power-hungry since the display stays on and the radio transmits continuously. Keep a charger handy for long sessions.
Can I use my phone normally while casting a video?
With app casting (Cast icon method), yes — the TV plays independently and your phone is free. With full screen mirroring, the TV shows exactly what your phone shows.
Is my phone compatible with USB-C to HDMI?
It needs USB-C Alt Mode / DisplayPort support. Most flagships have it; many budget phones and older Pixels don't. Check your model's specs before buying the adapter.
