Is it possible to gain complete remote access of another Android phone from my phone? In my phone (Samsung Galaxy On7, Android 6.0.1-Marshmallow), the internal memory is very insufficient, and moreover, important apps like MS word and Excel come inbuilt, due to which I cannot move them to the sd card.

I saw on the net that there are methods by which I can gain access over my desktop from my mobile through the Google Chrome Remote Desktop app. There are apps to do the reverse as well. But how can I gain access over another Android phone from my phone?

Actually, I want to use my father's phone, because in his one (Samsung Galaxy On5, Android 6.0.1-Marshmallow), the above stated apps can be moved to sd card. So, it would have been great if I could create documents or spreadsheets from my phone on his phone, and then bring them over to my phone by saving them in the Cloud. In this way, my phone can be saved from unnecessary space loss. I've spoken to him, and he has agreed, but now I need to know how I can do this.

How can I get complete remote access of another device from my device?

It would be best if I don't have to root my phone or that of my father's.
As far as I can tell, this seems to be achievable at least with the aid of applications such as TeamViewer
