In PCAPdroid, you can enable blocking of QUIC, which causes some apps to fallback to TLS, thus making them decryptable Decrypting QUIC traffic is not supported yet.TLS decryption is not available with the root capture.You should only do this if you know what you are doing and for a limited amount of time Note: running TLS decryption will weaken the security of your app.

Note: before decrypting, you should check the app ToS to see if this is allowed Debug protocol-related issues without disabling the TLS encryption.Reverse engineer the protocol of an app, e.g.Check if an app transmits sensitive information or unhashed passwords.Decryption can be useful in the following contexts: Such connections are reported in PCAPdroid with either the TLS or the HTTPS protocol. Most apps today employ TLS to secure their data against inspection and tampering. Moreover, it can generate a SSLKEYLOGFILE containing the decryption secrets, which can be used to decrypt the generated PCAP file in other tools.

Since version 1.5.0, PCAPdroid has the ability to decrypt the TLS traffic and display the decrypted payload directly into the app.
