How do I disable screen timeout of Android?

1. Use a script

You can use a script via the terminal to simulate a long action and prevent the screen from timing out. Create the script below and run via Terminal Emulator on your phone. It simulates pressing the letter r and Enter, then wait for a second before repeating the process for the number of times you choose with i.

1. Create a file and put the following inside of it.

#!/system/bin/sh



i=86400 #Put a big number here



while [ $i -gt 0 ]

do



i=$(( $i - 1 ))

input keyevent 46 #Write the letter r

input keyevent 66 #Simulate Enter key on the keyboard

sleep 1

  #Do nothing for 1 second



done

2. Save the file, give it a name for example test.sh. Open the terminal and navigate to the folder where the file is saved (if you don't know the path, use your file manager to get the path) with the command:

   
   
   

   cd /path/to/your/folder




3. Then execute the command:

   
   
   

   sh test.sh

The script will start running. When you no longer need it to run, just close the terminal.

2. Use an app

Caffeinate add a tile in the quick settings. In Caffeinate Settings, click on Caiffeine Tile, enable "Skip To Infinite Mode". Open the quick settings, click on the app tile. The screen should stays on until you press the tile again or click cancel on its notification.
