Nothing has pulled the Nothing Chats beta from the Google Play Store, saying it aims to address "several bugs" and postponed the messaging app's launch indefinitely.

Encryption lacking
This move follows a blog post, exposing that messages sent via Sunbird's system, the platform provider for Nothing Chats, lacked end-to-end encryption and were vulnerable to security breaches.

Message interception
9to5Google, citing Android developer Dylan Roussel, reported that Sunbird decrypts and sends messages using HTTP to a Firebase cloud-syncing server, where they are stored as unencrypted plain text.

More details
Roussel has discovered that Sunbird can access messages by logging them as errors via Sentry—a debugging service—contradicting Nothing's assertion that no one at Sunbird can access messages.

Uncertain future
The future of Nothing Chats is uncertain as it faces security problems and potential obsolescence due to Apple's RCS support.
