Hi Shubham, On a general note, it might be easier (in terms of information sharing) if you send us an email at support@portswigger.net and include some screenshots of the setup that you currently have and the issues that you are experiencing. To confirm, are you able to proxy HTTP and HTTP/S traffic from the browser on your mobile device through Burp and it is just traffic from the mobile apps that you are experiencing issues with or am i misunderstanding your forum post?

Hi, I have just replied to your email regarding this issue but will repost the information here. For versions of Android of 7 and above you have to install the certificate at the system level on a rooted device (Android changed the way that user supplied certificates are trusted in this version). The following is the best guide I have seen for this (if you follow from the 'Install Burp CA as a system-level trusted CA' section): https://blog.ropnop.com/configuring-burp-suite-with-android-nougat/ Essentially, you need to convert the certificate and then add it to a certain location on the file system of the device.
