Get your phone on the screen.

Pick your phone and how you're connecting. The steps below use the same words your phone shows you — and, for Android, the exact menu names for your brand.

iPhone over USB

Nothing to install on the iPhone. Three things, in this order.

  1. Use a Type-A to Type-C cable — plug into the back of the PC, or a USB 3.0 port on a laptop.Front-panel and hub ports are the most common cause of a link that never starts.
  2. Keep the iPhone unlocked and on the Home Screen. When it asks “Trust This Computer?”, tap Trust and enter your passcode.
  3. First time on this PC? Tap Set up this iPhone in Ocuulo Mirror, then restart the PC once.A one-time driver step. After the restart it mirrors on plug-in.
You're live. Your iPhone appears on the PC with audio — ready to record or send to OBS.

iPhone won't connect over USB?

No “Trust This Computer?” prompt appeared
  • Unlock the iPhone and keep it on the Home Screen while it connects — the prompt only shows on an unlocked phone.
  • Unplug and plug the cable back in with the phone already unlocked.
  • Use a data cable. Many bundled cables are charge-only and can't carry a mirror.
I tapped Trust but still no screen
  • First time with this iPhone? Click Set up this iPhone when prompted, then restart the PC once.
  • Won't start, or stuck on “connecting”? Use a Type-A to Type-C cable and a different USB port — the back of the PC works best.
Still stuck
  • Restart the iPhone (off, then on). This clears a stuck screen-broadcast.
  • Restart Ocuulo Mirror on the PC, then plug in again with the phone unlocked.
  • If it worked before and stopped: a different cable, then a different port, in that order.
Picture but no sound
  • Turn the iPhone's volume up — the mirror carries what the phone is playing.
  • Check the PC's output device in Ocuulo Mirror's volume control and in Windows sound settings.
  • On iPhone, BGMI and PUBG Mobile voice chat work normally, including when you stream through OBS. Free Fire's voice chat isn't shared with screen mirroring — that's an iOS limit.

iPhone over Wi‑Fi

Uses the iPhone's built-in Screen Mirroring. Nothing to install on the phone.

  1. Put the iPhone and the PC on the same Wi‑Fi.
  2. On the iPhone: Control Center → Screen Mirroring → Ocuulo.
  3. Keep both near the router — 5 GHz Wi‑Fi gives the smoothest mirror.

iPhone won't connect over Wi‑Fi?

Ocuulo isn't listed under Screen Mirroring
  • Same Wi‑Fi — the iPhone and the PC must be on the same network, not a guest network or one with “AP isolation” / “client isolation” on.
  • Wait a few seconds, or toggle the iPhone's Wi‑Fi off and on, then open Screen Mirroring again.
  • Make sure Ocuulo Mirror is open on the PC and set to iPhone over Wi‑Fi.
It connects but stutters or lags
  • Use 5 GHz Wi‑Fi and stay near the router. 2.4 GHz and walls are the usual cause.
  • For the lowest latency of all, use the USB cable instead.

Your phone brand

Brands name the same settings differently. Find yours and the exact menu names appear below.

Android without USB debugging

No Developer options. Set the phone up once, then it's plug in → Cast every time.

One-time setup on the phone

Ocuulo Mirror asks for a few permissions, each with its reason. A ring at the top counts what's left — tap it any time.

  1. Open Ocuulo Mirror on the phone.
  2. Display over other apps — find Ocuulo Mirror in the list and switch it on.Keeps the phone awake while it mirrors: a tiny invisible window holds the screen on. Nothing is drawn over your apps.
  3. Allow notifications.So Start is offered the moment you plug in.
  4. Battery — tap Allow, then let it run in the background.Each grant turns green and the ring counts down.
  5. Microphone — choose While using the app.Android needs it to send your phone's sound; its prompt calls it “record audio”. Ocuulo never records from your microphone.
  6. Open Manage app if unused and turn the switch off.So the phone never pauses Ocuulo.
  7. Back in App info, open Battery usage and choose Allow background activity. Confirm with Allow.Battery use stays normal in practice.
The ring is green — this phone is set up for good.

Every time: plug in and cast

  1. Plug the phone into the PC with its USB cable.
  2. When the phone asks, tap OK — and tick Always open, so it stops asking.
  3. Pick Entire screen, then tap Cast.That's Android's own screen-capture permission.
You're live. Everything on the phone's screen is on the PC.

Phone won't connect?

Nothing happens when I plug in
  • Make sure Ocuulo Mirror is installed on the phone and you tapped Start.
  • If the phone shows an “Open Ocuulo Mirror for this USB accessory?” prompt, tap OK (tick “always”).
  • Try a different cable or port — a charge-only cable can't carry data.
  • Unlock the phone. Some phones only offer the accessory prompt on an unlocked screen.
It connected once, now it won't
  • Unplug, wait two seconds, plug in again, and watch for the accessory prompt.
  • Restart the phone. A stuck USB accessory session clears on reboot.
  • Check the one-time setup above is still green — a system update can reset battery permissions.
The mirror stops after a few minutes
  • The phone's battery manager paused the app. Redo Manage app if unused → off and Battery usage → Allow background activity.
  • On brands with an Autostart switch, turn it on for Ocuulo Mirror — see your brand card above.
Still stuck
  • Use With USB debugging (the tab above), or mirror over Wi‑Fi.
  • Write to us with your phone model — team@ocuulo.com.

Android with USB debugging

Turn on USB debugging once, then it's plug in → Start every time.

Turn on USB debugging (once)

  1. Open Settings.
  2. Scroll down and tap About phone. Some phones call it About device.
  3. Tap Software information. Some phones call it Version.
  4. Tap Build number seven times. On some phones it's called Version, or Build version number.
  5. Developer mode is now on — the phone says so on screen.
  6. Go back, then open Developer options. It appears once developer mode is on.
  7. Turn on USB debugging, under the Debugging section.

Every time: plug in and start

  1. Plug in by USB. When your PC asks, tap OK and tick Always allow from this computer.
  2. Open Ocuulo Mirror on the phone, tap Start, and allow screen capture.
You're live. Your phone is on the PC screen with audio.

Phone won't connect?

The “Allow USB debugging?” prompt never appears
  • USB debugging must be ON — Settings → About phone → tap Build number 7×, then Developer options → USB debugging.
  • Unlock the phone — the prompt only shows on an unlocked screen. Unplug and plug back in.
  • Try a different USB port/cable, then re-tap Start in the phone app.
  • In Developer options, tap Revoke USB debugging authorisations, then plug in again to get a fresh prompt.
It's allowed but there's no screen
  • On the phone, open Ocuulo Mirror, tap Start, and allow the screen-capture prompt.
  • Choose File transfer (not “charging only”) when the phone asks what the USB connection is for.
  • Restart the phone, then plug in again.
The mirror stops after a few minutes
  • The battery manager paused the app. Allow Ocuulo Mirror to run in the background with no battery restriction — see your brand card above for the exact menu.

Android over Wi‑Fi

No cable. Scan a code or type a PIN.

  1. Put the phone and the PC on the same Wi‑Fi.
  2. Open Ocuulo Mirror on the phone and tap Scan QR code — point the camera at the code on the PC screen. It connects on its own.
  3. No camera handy? Tap Start instead — the app shows an IP address and PIN. Enter them in the PC app exactly.

Phone won't connect over Wi‑Fi?

It can't find the PC
  • Same Wi‑Fi — the phone and the PC must be on the same network. Guest networks and “client isolation” block this.
  • Check the PIN matches, then tap Start again.
Code not scanning
  • Wipe the camera lens and hold the phone about a hand-span from the screen.
  • No working camera? Type the 6-digit code into the phone app, or use Connect by IP under the code.
It stutters or lags
  • Use 5 GHz Wi‑Fi and stay near the router.
  • For the lowest latency, use the USB cable — without USB debugging it's just plug in and cast.
