How to Use Tube | YouTube Setup & Navigation Guide

For the full breakdown, see our best 3 Person Towable Tube guide.

Whether you just got your first smart TV or want the desktop app on your Windows PC, getting started with YouTube (often called “the Tube” in casual US slang) takes about two minutes. The official app is free, runs on everything from phones to game consoles, and only needs a Google account. Below is the exact setup path for every major device, plus the navigation and sign-in steps that trip up first-time users.

Installing YouTube on Mobile, TV, and PC

The official YouTube app by Google LLC is available on every modern platform. Installation varies slightly by device, but the process is the same: open the device’s app store, search for “YouTube,” confirm the publisher is Google LLC, and tap install.

• Android or iPhone: Open the Google Play Store (Android) or Apple App Store (iOS). Tap the search icon, type “YouTube,” and select the official entry published by Google LLC. Tap Install (Android) or Get (iOS), then Open once the download finishes.
• Smart TVs (Samsung, LG, Android TV, Apple TV, Fire TV): Go to the TV’s app store — Samsung’s Apps, LG’s Content Store, or the Play Store on Android TV. Search “YouTube” and select Download or Add. On PlayStation and Xbox, use the PlayStation Store or Microsoft Store to find and install the app.
• Windows PC: Open Google Chrome and go to youtube.com. Click the three-dot menu (top right), select Save and share (or “Cast, save, and share”), then click Install YouTube. Confirm by hitting Install in the popup. You can also click the small download icon in Chrome’s address bar and choose the same option.

Signing In and Creating a YouTube Channel

Once the app is installed, tap Sign in (top-right corner) and enter your Google or Gmail account credentials. If you don’t have a Google account, create one first at accounts.google.com — it’s free. To start your own YouTube channel, go to Settings > Add or manage YouTube channels > Create a channel. Pick a name (your real name or a brand name) and confirm. A success screen shows your channel is live.

One catch: each mobile number can verify only two YouTube channels. If you plan to run multiple channels, reserve that verification slot carefully. If you’re setting up YouTube on a TV, you’ll need to sign into your Google account on a phone or computer first, then enter the activation code displayed on the TV screen.

Navigating the YouTube App and Avoiding Common Mistakes

The app’s home screen shows recommended content based on your watch history. Use the Search tab (magnifying glass icon) to find specific videos or channels. The Subscriptions tab lists every channel you follow, while the Library tab holds your watch history, playlists, and downloaded videos. On smart TVs, these tabs appear as a horizontal menu across the top of the screen instead of a bottom bar.

Most common mistake: downloading an unofficial app. Fake YouTube apps exist on some storefronts and may contain ads or malware. Always verify the publisher name reads Google LLC — not “YouTube Tools” or “Video Downloader.” A second mistake is using the wrong Google account on shared devices; double-check the profile icon in the top-right corner before broadcasting or adding videos to playlists.

YouTube on Smart TVs: Activation Code Setup

Some smart TVs and streaming devices require an activation code the first time YouTube opens. The screen displays a short alphanumeric code and a URL (youtube.com/activate). On your phone or computer browser, go to that URL, sign into your Google account, and enter the code. The TV will refresh automatically and show your account. This step is needed once per device.

If the activation screen does not appear, try restarting the TV app or checking your internet connection. The code expires after a few minutes, so have your phone ready before opening the TV’s YouTube app.
