I am using Burp as a proxy to test an Android app. To get this to work I installed the Burp CA certificate on my phone. As far as I understand it (and that is not a lot of understanding) I could leave this certificate on my phone without adding a large security risk, as the CA certificate is created by Burp for the specific instance/device.
But I am not sure about this, so the question is: What security risks am I introducing to my personal phone when leaving the Burp CA certificate installed instead of deleting it after testing? And why?
