Using Android Phone as Raspberry Pi's Display

It's not a big deal to make an Android phone function as a Raspberry Pi's display; it is done by a method called Virtual Network Computing(VNC). Just follow the simple steps provided below,

Note: For this project, we need monitor for the first time we do.

Step 1: Install VNC on Raspberry Pi

For this project, I use RealVNC. This comes along with the latest Raspbian OS with Virtual Assistant or open the terminal in Raspberry Pi and type the following commands to install RealVNC in Pi.

sudo apt-get update
sudo apt-get install realvnc-vnc-server realvnc-vnc-viewer

Step 2: Enable VNC in Pi

Select Menu > Preferences > Raspberry Pi Configuration > Interfaces and set VNC as Enabled or type the following command in the Terminal window.

sudo raspi-config

Go to Advanced Options > VNC and click Enable, then click Ok.

Step 3: Establishing Direct Connection

Download VNC Viewer Android App from the Play Store & turn on the hotspot in the Android Mobile. Connect the phone and the Pi in the same network and find the IP address of the Pi by typing following command in the Terminal:

hostname -I

Now, follow the instructions with images to connect.

Now the Raspberry Pi's screen appears on the phone, and if an error occurs, just make sure the Pi is connected in the same network.

Step 4: Cloud Connection

The above step works on a local area network. For controlling remotely, we need to create an account in RealVNC and sign into the app to get the cloud connection.

Sometimes there can be a problem in the connection. Check here for troubleshooting. For further advanced options and instructions you can refer here.
