Are you away from home and need to access your computer for some stuff? Are there any relatives or friends at your home at that moment? With little help from them, you can access your PC from anywhere around the world.
You need to make sure that someone should be able to turn on your remote computer and it must be online. It will enable you to control pc from your phone without any issues.
Avoid the remote computer from going to sleep mode. Though your device can be still connected to the remote computer, you cannot awake the screen from Android (controller device). It would be a good choice to turn off the sleep mode permanently in the display settings on your Windows PC.
One of the fine advantages of remotely accessing a computer is that you can offer technical support to your family member or friend. You need to use the right tools both on your PC and Android device for remote access.
Chrome remote desktop is the safe and free tool provided by Google which needs to access a PC from Android. You can use the keyboard and mouse feature in Chrome remote desktop for navigation.
Chrome remote desktop works fine on Windows, MAC, Linux, and Chrome OS. As the name implies, I would recommend you to use the Chrome browser.
