Telegram gives you an option where you can select who can see your last seen time. To configure this, go to “Settings”, “Privacy and Security” and then tap on “Last Seen & Online”. You can share it with everybody, or people in your contact list, or nobody, or add exceptions like “never share with” XYZ.

Join Requests for Public Groups Telegram now allows you to add people who are near you. If the person on the other side has made his/her profile visible, you can see his/her name in the search. Just tap on the name to exchange contact info. What makes Telegram unique is its focus on privacy, encryption, and an open-source API. There are countless unofficial clients to go along with the official Telegram apps and web interface. It also allows multiple devices to use the same account (verified by SMS), and multiple accounts on the same device. With the ability to send files up to 2 GB (or 4 GB), users can easily share large media items from other apps directly to Telegram on any mobile platform. This saves both time and storage space – so you don't have to save the file before sending it in Telegram.

It will make it a bit more convenient for you to identify the alerts from a specific Telegram chat. Keep in mind that the audio clip must be less than 5 seconds and up to 300KB in size. Edit Videos
