How can I project my phone screen on the wall without projector app?

You can project your phone screen onto a wall without using a projector app by using one of the following methods:

1. Using a Phone with a Built-in Projector

Some older smartphones, such as the Samsung Galaxy Beam, come with built-in projectors. If you have such a phone, you can use the phone’s native projection feature to display your screen or content onto a wall. However, these models are rare today.

2. DIY Phone Projector

If your phone doesn’t have a built-in projector, you can create a simple DIY projector using your phone’s flashlight or screen and some basic materials.

Materials Needed:

• A magnifying glass (this acts as the lens for focusing the image)
• A cardboard box (shoebox or any similar-sized box)
• Tape or glue (to hold everything in place)
• Scissors or box cutter (to cut holes)
• Your phone

Steps:

1. Prepare the Box: Find a cardboard box (a shoebox works well) and cut a hole near one end large enough to fit your magnifying glass.
2. Place the Magnifying Glass: Secure the magnifying glass over the hole. The magnifying glass will act as the projector lens.
3. Set the Phone in the Box: On the opposite side of the box, place your phone in a holder so that its screen faces the lens. The phone should be positioned a few inches away from the lens.
4. Adjust the Projection: Once everything is set up, turn on your phone and adjust the distance between the phone and the lens to focus the image. You can also adjust the box's distance from the wall.
5. Start the Projection: Place the box facing a blank wall and turn the lights off for better clarity. Your phone’s screen should now be projected onto the wall.

3. Using a Chromecast or Screen Mirroring

You can use screen mirroring or wireless display features to project your phone’s screen onto a TV or monitor, and if you connect it to a large TV with a white or light-colored wall behind it, it may look like you're projecting it onto the wall.

Steps:

1. Use Chromecast:

   • Plug a Chromecast device into your TV.
   • On your phone, open the Google Home app and connect it to the Chromecast device.
   • Tap Cast Screen and select your Chromecast device. Your phone screen will be mirrored to the TV.

2. Screen Mirroring with Apple TV (iPhone):

   • For iPhones, use AirPlay to mirror your screen to an Apple TV.
   • Make sure both your iPhone and Apple TV are connected to the same Wi-Fi network.
   • Open Control Center on your iPhone and select Screen Mirroring.
   • Choose your Apple TV, and your iPhone screen will be projected onto your TV.

3. Using a Wired HDMI Connection:

   • For Android phones or iPhones with a USB-C to HDMI or Lightning to HDMI cable, you can connect your phone to an HDMI-compatible TV or monitor. The phone screen will be displayed directly on the larger screen.

4. Using a Smart TV’s Screen Mirroring Feature

Many modern smart TVs have built-in screen mirroring or casting features, allowing you to wirelessly project your phone screen onto the TV. Once connected, you can project your phone’s screen to the TV and, if you want to project it onto a wall, simply position a white or light-colored background behind the TV.

Steps for Android:

• Go to your phone’s Settings.
• Tap Connections or Display.
• Select Cast, Screen Mirroring, or Smart View.
• Choose your TV from the available devices.
• Your phone screen will be mirrored to the TV.

Steps for iPhone (Apple TV or AirPlay-Compatible TV):

• Open the Control Center on your iPhone.
• Tap Screen Mirroring and select your compatible TV.
• Your phone screen will be projected onto the TV.

5. Using a USB-C to HDMI Adapter (For Android Devices)

If your Android phone supports USB-C with video output, you can use a USB-C to HDMI adapter to connect your phone to an HDMI-compatible device like a TV, monitor, or projector.

Steps:

1. Plug the USB-C to HDMI adapter into your phone.
2. Connect the HDMI cable from the adapter to your TV or monitor.
3. Switch your TV to the corresponding HDMI input.
4. Your phone screen should now appear on the connected TV, and you can project it onto a wall.

Conclusion:

To project your phone screen onto a wall without an app, you can either create a DIY projector using basic materials or use screen mirroring techniques with a smart TV, Chromecast, or an HDMI connection. While the DIY method works best in dark rooms, screen mirroring options allow for a more convenient solution if you have access to a compatible TV or device.
