Turn an old Android into a streaming stick

turn an – An old Android phone can become a free, DIY streaming stick: install a TV-style launcher, keep the screen awake while you cast, and use native casting (when supported) for smoother playback.

One of the hardest parts of living with tech is the drawer full of it. Phones you kept “just in case,” chargers you couldn’t quite throw out, screens that still light up—but only in the dark. For one long-time device tester, that pile became a plan.

After recently turning an old Android phone into a Wi‑Fi extender, the idea clicked: could one of her other spare phones replace a streaming box—something closer to Roku or Fire TV? Not in theory. In minutes, in the living room, with the same phone serving as the remote.

The setup is built around a simple promise: your phone becomes a streaming command center with a TV-style interface, your TV handles the video, and casting does the heavy lifting.

To do it, you start with what you already likely have: a spare Android phone, an internet-connected TV or display that supports casting or screen mirroring, a charger, a launcher, and maybe a dedicated casting app.

The phone matters too. It should run a relatively recent Android version, have Wi‑Fi, enough storage for streaming apps, and a decent battery. The TV side matters for the same reason—this only works if your display can receive what your phone sends.

The first move is straightforward: connect the Android phone to the home Wi‑Fi network and make sure the TV is on the same network.

Then comes the part that changes everything about how it feels. Instead of using the phone’s standard home screen, the phone gets a TV-style launcher.

In this case, the author installed TV Launcher for free. There are other options in the Play Store too. including Projectivy Launcher. Easy TV Launcher. or ATV Launcher Pro. which costs $2.99. After installation. the launcher lets streaming apps show up as large. rounded tiles in a simple row or grid. with colorful artwork and a clean look that’s meant to be readable from across the room. It also allows hiding or rearranging apps and making folders.

Because the phone is now effectively acting like a streaming box you carry around, the next step is about preventing it from going dark at the worst moment.

The author recommends changing settings so the screen doesn’t time out while casting: go to Settings, then Display, and increase the screen timeout to 30 minutes or more.

For a more permanent fix. she enables Developer options by going to Settings > About phone. then tapping Build number seven times. Under Developer options, she turns on Stay awake so the screen remains on while charging. And during playback, the phone stays plugged into a wall charger to avoid it dying halfway through a movie.

When it’s finally time to watch. the process is almost ritual-like: with the launcher open. the author opens Quick Settings on the Android phone and taps Cast. On some phones it may appear as Screen Cast or Smart View. If it isn’t there, she says to tap the pencil icon to edit Quick Settings and add it.

With the launcher in place, streaming apps are big enough to browse comfortably. You pick something on your phone, tap play, and the video goes to the big screen.

One choice decides whether it feels like a seamless streaming device or a finicky workaround: native casting.

The author says native casting often works better than full-screen mirroring. The rule of thumb is simple—if a streaming app has a cast icon, tap it. Then use the phone as the remote. In her experience, this leads to smoother playback, less battery drain, and fewer audio delays.

She also points to dedicated casting apps as options when you need them. Castify is free with ads, with an optional ad-free upgrade. Web Video Cast is another free option with a premium upgrade tier. She notes it’s useful for videos you want to watch from a site like CNN. rather than from a major streaming app. and it supports local files and subtitles.

There’s also a wired route for people who hate lag. A wired HDMI connection could make phone-to-TV streaming more lag-free by sending video through a cable instead of relying on Wi‑Fi—though only some Android phones support it.

For her own setup. she used a Pixel 9a—released in 2025—with 128GB of storage and 8GB of RAM. paired with an 85-inch Samsung 4K TV. Once the launcher was set up, streaming apps were installed, and casting behavior was chosen, she was ready. She grabbed the phone with the launcher open. picked an app and a show. casted. and controlled playback from the phone.

There’s a limit that matters to real-world expectations: DRM-protected apps may block screen mirroring from Quick Settings but still allow casting from inside the app. Support varies by app and plan. Many services she names as offering native casting include Disney+, Max, Prime Video, Peacock, YouTube TV, and Tubi.

In day-to-day life, she doesn’t pretend this replaces a Roku or Fire TV forever. “At home,” she says, she probably wouldn’t use an Android phone as a streaming device all the time. But for travel—hotels or Airbnb—she sees the appeal. It’s a way to dust off an old spare phone. give it a second life. and turn it into something surprisingly useful.

Still, it’s not perfect, and she’s explicit about why. Wired casting can be more reliable, but wireless casting can lag. Some streaming services support native casting but block full-screen mirroring. In those cases. a streaming app may cast normally through its own Cast button while mirroring shows a black screen. an error message. or no video.

She also draws a clear line between how the two methods work. Native casting sends the video stream directly to the TV and lets the phone act as a remote. Full-screen mirroring duplicates everything on the phone screen onto the TV. meaning using the phone while mirroring shows those actions on the TV.

And yes—the price can be zero. She says the setup is free if you already have the Android phone and TV, use a free launcher, and plan to stream from an ad-supported service such as Tubi. In that case, you don’t need to pay for the movies and shows you watch.

If you want to test whether your phone can handle wired HDMI. the author’s method is practical: plug in a USB‑C to HDMI adapter. connect it to the TV with an HDMI cable. and choose the correct TV input. If nothing appears, your phone probably doesn’t support wired video output. She adds that many Samsung phones support wired HDMI, as do Pixel 8 and newer models, and some Motorola Edge phones.

Finally, she warns against turning the phone into a permanent plug-in device. It’s “not great for the battery.” Her advice is to use a well-reviewed charger, keep the phone ventilated, and unplug it when not in use.

In the end, the most human part of the story isn’t the tech—it’s the decision to stop letting old devices sit idle. In her hands, an abandoned phone became a remote, a menu, and a streaming hub, with the TV doing what it does best.
