Con Currently no file transfer is available
Con Centralized architecture
Signal's server architecture has been partially decentralized since December 2013, when it was announced that the messaging protocol that is used in Signal had successfully been integrated into the Android-based open-source operating system CyanogenMod. As of CyanogenMod 11.0, the client logic is contained in a system app called WhisperPush. According to Open Whisper Systems, "the Cyanogen team runs their own Signal messaging server for WhisperPush clients, which federates with Open Whisper Systems' Signal server, so that both clients can exchange messages with each-other seamlessly".
The WhisperPush source code is available under the GPLv3 license. In January 2016, however, the CyanogenMod team announced that they will be discontinuing WhisperPush on February 1, and recommended that its users switch to Signal. After this, Signal's server architecture will be entirely centralized.

Con Code being used in Whatsapp and other parties undermines trust
