comment What is the purpose of pre master secret in SSL/TLS?
@MaartenBodewes I disagree: this is not an IT security question, it's a protocol design question. Protocol design is cryptography.

comment Is there a need to encrypt data when send over https?
There are three parts here: the browser on Android, the proxy, and the server. What exactly did you install on Android? Is this a certificate for the server or for the proxy? What did you install on the proxy? How did you arrange for the proxy to be a man-in-the-middle? If what you did was to tell Android to trust a certificate for which the proxy has the private key, then this is perfectly normal: you told Android to blindly trust your proxy. In other words, if that's what you did, you opened the door and are now complaining that the zombies are coming in. The solution is: don't do that.
