How To Project Mobile Screen on Wall Without Projector – Complete Guide

If you are looking for methods on how to project mobile screen on wall without projector then, there are ways that it can be done. There are several different methods of projecting the image of your phone on any surface. Some work better than others, so this article will help you decide which would be best for you. First, however, let’s have a look at why it is even possible to do this in the first place.

Mobile users often find themselves confused when trying to get their devices’ screens onto another flat surface besides their own device’s screen or an external monitor/projector that they may possess. This article explains how one can accomplish this seemingly complicated task by utilizing some basic equipment and following certain steps.

While many mobile phone users do not know that their phones can be used to project an image onto a flat surface beyond the screen itself, there are in fact several ways to accomplish this task.

Method 1 To Project Mobile Screen on Wall Without Projector:

The first and easiest way to project your device’s screen is to place it on a table or hold it up in front of you and press one of the device’s buttons that are designated for turning on the flashlight. When your phone is in this mode, its camera flash will come on and project any objects/images onto a surface facing you.

If you need to cast your screen image onto something larger or further away than just a tabletop, you’ll have to use more advanced equipment.  By using a laser pointer and the camera flash feature on your phone, you can project an image onto any surface that is facing you. This will enable you to see what’s on your device’s screen from further away than just in front of it.

The reason why this works is that when the laser pointer shines onto a flat surface (like a blank wall), the invisible light waves reflect back towards you off of that surface making an image appear as if it were projected by a small projector—which is essentially what this technique does for your mobile device.

The technical term for this type of activity is called “shadow casting” or “projecting shadows.” The reason that you can’t just project onto any flat surface with your device is that the laser pointer doesn’t have enough strength to push through objects, so if there’s anything between the wall and your device it won’t work.

Method 2 : Using Telefoto Dedicator

There is another way to make your mobile display appear on a wall without using any computer, projector, or other complicated devices. This method depends on the fact that most phones today have cameras with flashlights. Therefore your phone can be used as telefoto dedicator (projector) if you know how to use it properly.

Telefoto Dedicator App that is available in Google Play Store for free.

How it works:

This app uses your phone’s flashlight to project an image onto a wall, ceiling or any other surface from a small distance away. In order to get the best results, you should place your device at least 15 inches away from the wall and make sure there are no obstacles between the two to avoid casting a visible shadow on the screen. You can also use this application to make a presentation easier by projecting an image onto a whiteboard rather than having to write everything down yourself.


  • Simple and easy-to-use interface
  • Lightweight and fast
  • Automatic detection of available devices
  • Automatic image rotation to correct orientation
  • Operates in portrait or landscape mode •Displays a grid on the device’s screen for alignment purposes


  • Great app to use when you need to make presentations, watch online videos or play games with others.
  • Free application without any advertising.


  • App only works on phones with flashlight (sorry iPhone users).
  • The telefoto dedicator application does not support all types of image formats (.JPEG, .JPG)

Other than using your phone as a home movie projector, this app can also be very helpful when playing with your kids outside at night. In fact,  telefoto dedicator is a great tool to have when you decide to take part in a campout or if you just want to have some fun in the dark. But be warned, the battery life will drain quickly so make sure you have an extra charger nearby.

Mobiles with built-in Projectors:

Four smartphones have built-in projectors for easier sharing of videos, pictures, and other media.  They are the HTC HD7, Sony Ericsson Xperia X10 Mini Pro, Sony Xperia Ray, and Motorola Atrix HD.

Android phones have built-in projectors but they are not very powerful. Therefore several Android fans developed an application called Beam that allows streaming content from your Android device to any DLNA compatible device (like TV or projector). The best part is that this app is completely free! Besides allowing the user to stream videos and images from their phone to any other screen without cables, Beam has some extra features like zooming in on video content..
