My friend and I were discussing cell phone security and he said that if someone backdoored your phone that they could read all your signal messages. Is this true? I would think that the only way to view signal messages is to literally open up the app and view them.

    If a device is compromised, the adversary can do whatever they want: screenshots, keyloggers, fork Signal and install their own client.

    Try molly – hardened fork of signal. With encrypted keys as soon as you lock it after using the app it shreds itself from ram.

          But you can view the messages on your phone, so they are decrypted at some point. Then an attacker can steal the key and read them whenever they want. Or they just take screenshots when you use the app if they are lazy.

            Molly has a feature, which prevents screenshots. Also everywhere you are in danger of password stealing, bruteforce attacks, etc.

              Molly has a feature, which prevents screenshots.

              Again, if you can see it on the screen it’s possible to steal it. (How easy it is depends on the driver)

              Molly (or any app) won’t help you if your phone is compromised, unless you set a pin to lock your messages and never unlock it after being compromised. (which is unlikely)
