Im using Qpython3 on Android 4.2.2. Im currently able to list the latest sms from a particular contact and extract a 10 digit phone number. I want to update a contact's phone number with this number. 
How should I do this ?
To be more precise, I want to be able to:

Access the contact list.
Update contact phone number with this phone number

Is this possible with Qpython3 ?
Try to run it in console because you can communicate with the interpreter directly
