Do you want to operate your laptop or personal computer right from your Mobile? - here is the one of the ways and it is a bit old way but I am re-sharing for you.
Chrome Remote Desktop:
If you have Chrome Browser you have to install an app called 'Chrome Remote Desktop' from its app store. You can launch this app store from your browser by typing 'chrome://apps/' and click on 'web store'.
Once the app is installed - Connect this application to your GMail id and click on 'Launch Application' and from the down 'My Computers' - click on 'Enable remote connections'
Give a 8 PIN for security purpose.
This is from Laptop / Computer end. Now you have to install the same application in your Android App Store - on your mobile.
Launch the application with the same gmail id you have registered on your computer's app.
Once you enable your laptop/computer with 8 PIN - then you can see the list of available computers to login and see. Give the same PIN and you can start accessing your laptop/computer right from your Mobile.
Here is some screenshots which I have taken from my mobile.
From the Chrome Application - you can ask get the Remote Assistance from your friends also.
Don't forget to disable the connections once you have used. Later you can again enable anytime you want.
Please share with your friends, because in Knowledge
Sharing is Gaining
