IMPORTANT: RingCentral will require TLS 1.2 and later encryption protocol beginning December 1, 2018.
Android versions older than 4.4 don’t support TLS 1.1/1/2 and therefore are no longer supported by the RingCentral mobile apps. Applications such as RingCentral Phone, RingCentral App (Glip), and RingCentral Meetings running on these devices will stop working when TLS 1.0/1.1 are disabled.
Android users running 4.4.x version and older are suggested to upgrade to the latest version of the Android OS.
