Send Uncompressed Media 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. To create one of these, go to Settings or a Chat Info page, click Edit > click the Profile Picture > select Sticker or Emoji.
Telegram Schedule Options If you want to use Telegram in a region where it's blocked, you'll appreciate the Telegram function that allows you to connect via a proxy server. Most of the time, it's better to use a VPN on your phone, but a proxy can still help you get around regional restrictions. Telegram offers a few other handy options in chats. You can delete any message by long-pressing it, then hitting the Trash icon that appears. The app lets you delete messages at any time—even messages that the other person sent in a chat.

To create a channel, right swipe on the homepage, and tap on “New Channel”. Provide your channel name, description, select channel type, and create a unique URL. That’s it. To lock your messages, go to “Settings”, “Privacy and Security” and tap on “Passcode Lock”. You will be asked to set a four-digit passcode and confirm it. Once you do that, you will find additional options to “unlock the app with fingerprint” and “auto-lock” it after a specific duration. To enable this go to Settings and choose “Privacy and Security” from the list. Next, tap on “Passcode Lock” under the Security heading, then set your password lock on! You don’t have to start from scratch to make Telegram apps. TDLib (Telegram Database Library) makes it easy to develop feature-rich and secure apps. It takes care of local data storage, network implementation details, and encryption so that you can focus on design and interfaces.
Telegram Attachment Options The encryption is based on 2048-bit RSA encryption, 256-bit symmetric AES encryption, and Diffie–Hellman secure key exchange.
