The TCL Roku Remote App: How to Set It Up on Any Phone

I run a TCL 4-Series Roku TV (43S435) and control it from both a Pixel 7 and an iPhone 15, depending on which is charged. When the stock remote's battery door snapped off, I went a month on the phone alone. My honest take: the official Roku app is the most complete on either phone, but the mandatory account is a speed bump — so for a quick, no-login remote I reach for a universal app, and I only open the Roku app when I want private listening through my earbuds.

This guide covers the TCL Roku remote app on any phone — Android or iPhone — with exact steps and the honest catch for each. Want the first-time pairing walked through in fuller detail?

The 30-second test

Before you download anything, figure out which app fits. It comes down to whether you want a Roku account and which features you need. This quick check points you at the right method below.

1. 1Want the exact button layout, voice, and private listening? The official Roku app (Method 1) is the fullest, but it needs a free Roku account.
2. 2Want a remote with zero sign-in, or you also own a non-Roku TV? A universal app (Method 2) skips the account and covers both platforms.
3. 3Already paired and just want headphones or voice search? Jump to Method 3 for the two features people miss most.

Method 1: Install the official Roku app

A TCL running Roku is a Roku device, so Roku's own app is the official remote — there's no separate TCL download. It's the most complete option: the exact button layout, keyboard search, voice, and private listening through headphones on your phone. Roku publishes it for both platforms on roku.com.

1. 1Install the free Roku app on your phone. Open the Google Play Store or the App Store, search for the official Roku app, and install it. It's the same app for Android and iPhone, and it treats your TCL Roku TV like any other Roku device.
2. 2Sign in with a free Roku account. Open the app and sign in, or make an account — it's free. The official app won't pair until you're signed in, so this step is not optional with Roku's own app.
3. 3Join the same Wi-Fi as your TCL Roku TV. Put your phone on the exact network the TV uses. Phones have no infrared, so the app reaches the TV over shared Wi-Fi. A guest network or a 5 GHz-only band the TV can't see is the usual reason pairing fails.
4. 4Open Devices and tap your TCL. Tap Devices at the bottom of the app and wait for the scan. Your TCL Roku TV shows up by name — tap it, and enter the on-screen code if the app asks. Now the D-pad, keyboard, and search all work from your phone.

Catch: the Roku account sign-in is required before the app will pair, and the app only drives Roku sets — a TCL Google TV in the house needs Google's app instead. If the scan just spins, work through the TCL Roku remote not working checklist, which covers app pairing as well as the plastic remote.

Method 2: A no-account universal app

If the mandatory Roku account puts you off — or you also own a non-Roku TV — a universal app skips the sign-in entirely. Smart TV Remote finds your TCL Roku on the network and connects with no account, and the same app also pairs with TCL Google TV sets, so one download covers a mixed household.

1. 1Download Smart TV Remote free from the App Store or Google Play on your phone or tablet.
2. 2Put your phone on the same Wi-Fi as the TCL Roku TV — no infrared means it works over the network.
3. 3Open the app, let it scan, and tap your TCL Roku in the detected list. No code or account needed.
4. 4Use the D-pad, OK, volume, playback, and the phone keyboard for fast search.

Catch: private listening through headphones is a Roku-app feature, so a universal app may not offer it. For that one perk, keep the official app installed alongside — the two coexist fine on the same phone. Own a Google TV TCL too? The TCL TV remote app overview maps which app controls each platform.

Method 3: Turn on private listening and voice

Two features make the app better than the plastic remote, and most people never find them. Private listening pipes the TV's audio to headphones on your phone — great for late nights. Voice search saves you pecking at an on-screen keyboard. Both live in the official Roku app.

1. 1Private listening: in the Roku app, tap the headphones icon on the remote screen, plug in or pair earbuds to your phone, and the TV's sound moves to your ears. The TV speakers go quiet.
2. 2Voice search: tap the microphone icon and say a title or app name. The app types it into the Roku search for you — faster than the D-pad keyboard.
3. 3Keyboard entry: when a text box is on screen, the app pops your phone keyboard so you can type passwords and searches at normal speed.

Catch: private listening needs the official Roku app and can lag audio slightly behind the picture on some phones. If the mic never triggers a search, check that the Roku app has microphone permission in your phone's settings. Roku documents both features on its mobile-app support page.

Fix 1: When the app won't connect

If an app keeps scanning and never lists your TCL Roku, the cause is almost always the network or one TV setting. Work through these in order — they apply to the official app and universal apps alike.

1. 1Match the Wi-Fi exactly: confirm the phone is on the same network name and band as the TV, not a guest or 5 GHz-only network the TV can't see.
2. 2Enable app control on the TV: open Settings › System › Advanced system settings › Control by mobile apps and set it to Enabled (Default or Permissive).
3. 3On an iPhone, allow Local Network access for the app in iOS Settings, and turn off any VPN or iCloud Private Relay — both hide the TV from the scan.
4. 4Restart both: power-cycle the TV at the wall for 30 seconds, force-close the app, and try the scan again on a fresh launch.

Honest note: some older routers block the local discovery apps rely on (AP isolation or IGMP snooping). If nothing above works and no phone app can find the TV, that router setting is the likely culprit — a wired Ethernet run to the TV sidesteps it.

Which app fits your phone?

Both apps control a TCL Roku TV from Android or iPhone. They differ on whether you need an account, whether private listening is included, and whether they also reach a non-Roku set.

My pick for most people: grab the no-account universal app for everyday control, and add the official Roku app if you want private listening. If the app can't reach the TV at all, the remote code guide covers programming a physical universal remote as a backup that needs no Wi-Fi.
