How to wirelessly share tablet screen with someone far away? I bought an Android tablet for my grandma (Amazon Fire 8 HD -  but I got Google Play Store working) and if she has any questions I want her to be able to share her screen with me (I live far away).   

I want to see her tablet screen on my Android phone or my PC.
As an additional feature I would like to be able to talk to her to say what she should do. 

Basically what I want is exactly what Skype can do on a PC (talking and screen sharing) unfortunately the Skype Android app can't do that(?). 

I found a few apps like "ScreenShare" and others but they didn't seem to work when our devices are in different WiFi Networks. Does anyone know an app or a way that can do the trick?
Using computer

I think the best mobile screen share is to show the screen on your computer and then share your computer screen with your friend.


user the vysor to share your Android device screen on your computer with Chrome easily and quickly.
then use TeamViewer to share screen with friends quickly


both of them are free for personal use and I had used them to help my parent to solve the issue on their mobile phones.

Control Mobile Directly

The another suggested app: TeamViewer QuickSupport app


install TeamViewer on your computer
install TeamViewer QS on your grandma's tablet, get the "Your ID"=> ID
Use the ID in step2 to send a request to connect your grandma's tablet.
Your grandma need to accept the request
Then you will see the screen on your computer





You can request screen capture, remote control, and see the app list on this interface.
Maybe the remote controlling needs root permission on the tablet. If it need, please try to install Super Su.
