You turn on screen record a little differently depending on your device. Here are the main ways, plus a quick forum-style explanation.

On iPhone (most common case)

  1. Add Screen Recording to Control Center (if it’s not there)
    • Open Settings.
    • Tap Control Center.
    • Tap Customize Controls or just see the list of toggles.
    • Find Screen Recording and tap the green + to add it.
  2. Start a screen recording
    • On iPhones with Face ID: swipe down from the top‑right corner to open Control Center.
    • On older iPhones with a Home button: swipe up from the bottom.
    • Tap the circle inside a circle icon (Screen Record).
    • You’ll see a 3‑second countdown , then everything on your screen starts recording.
  3. Record with microphone sound (your voice)
    • In Control Center, press and hold the Screen Record button.
    • A menu appears; tap the Microphone to turn it on (it turns red when active).
    • Tap Start Recording.
  4. Stop the recording
    • Tap the red status bar (or red pill/clock) at the top and choose Stop , or
    • Open Control Center again and tap the Screen Record icon to stop.
    • Your video will be saved in the Photos app.

If you opened Control Center and don’t see the icon, it almost always means you haven’t added Screen Recording in Settings → Control Center yet.

On Android (modern phones, Android 11+)

Steps vary slightly by brand (Samsung, Pixel, etc.), but the idea is similar:

  1. Open quick settings
    • Swipe down from the top of the screen twice to open the full quick settings panel.
  2. Find Screen Record / Screen Recorder
    • Look for “Screen Record” or “Screen Recorder” in the tiles.
    • If you don’t see it, tap the little pencil/edit icon and drag the Screen Record tile into the active area so it shows up.
  3. Start recording
    • Tap Screen Record.
    • Choose if you want:
      • Device audio only,
      • Microphone only, or
      • Both.
    • Optionally enable “show touches” if you want taps to be visible.
    • Tap Start ; there’s usually a short countdown, then it records.
  4. Stop recording
    • Tap the red notification or the stop button in the overlay.
    • The video is typically saved in Photos / Gallery → Movies / Screen recordings (exact folder name can differ by brand).

On Windows (built‑in Xbox Game Bar)

  1. Press Windows key + G to open Game Bar.
  2. Click the Record button in the Capture widget, or press Windows key + Alt + R to start/stop a recording.
  3. Recordings are normally saved in Videos → Captures.

On Mac (macOS Mojave and later)

  1. Press Shift + Command + 5.
  2. Choose to record the entire screen or a selected portion.
  3. Click Record.
  4. Click the small stop icon in the menu bar when finished; the recording appears as a thumbnail, then saves (by default) to the Desktop.

Quick “forum style” recap

To “turn on” screen record, you usually need to:

  • Add the Screen Record control (iPhone: Settings → Control Center → add Screen Recording; Android: edit Quick Settings and add Screen Record).
  • Open Control Center / Quick Settings.
  • Tap the screen record icon, wait for the countdown, then stop it from the status bar or notification.

If you tell me your exact device model (e.g., “iPhone 13”, “Samsung Galaxy S22”, “Windows laptop”, “MacBook Air”), I can give you a super targeted, step‑by‑step version just for that.
