The fact that Telegram allows users to create and install their custom theme makes using the service a joy. This is one of my favorite Telegram Messenger tricks.

To enable or disable this service, go to “Settings”, “Notification and Sounds”, and swipe down to the “Other” section. You will also find a “Repeat Notifications” option, which you can select as per your convenience.
