Perhaps the most important and the best feature of the Telegram app is its security. It is based on the MTProto protocol that is built upon time-tested algorithms. It enables high-speed, reliable message delivery on weak connections. There are times when we know our close ones studying, sleeping, or attending meetings, but we want to send some messages without disturbing them. Well, there is a feature called Silent Messages on Telegram. Basically, you can send messages and it will not make any sound or vibration even if the recipient has not turned on DND. That’s great, right? So to use this feature, type out your message and then tap and hold the “send” button. Here, choose “Send without sound” and you are done. When multiple users share their live location within a group, they’re displayed on an interactive map. To use this feature, choose “location” from the attachment menu and tap on “Share my location for…”
To find more themes, Android users can try the Themes for Telegram app. If you use an iPhone, have a look at the Telegram Themes subreddit. Besides these security enhancements, you can set a self-destruct timer of duration varying from one second to one week. Furthermore, you or the other person cannot forward messages that you receive within the Secret Chat and taking screenshots (or screen recordings) is completely blocked. Currently, the Secret Chat is limited to conversations between only two people and Secret Groups are not supported within Telegram. Private Chats in Telegram Settings To lock a chat go to Settings->Privacy and Security->Passcode Lock and enable it. Once you create a passcode and enable it, you will be able to lock and unlock your chats by tapping on the lock icon at the top right of the app.
Plus, if you’re using the “secret chats” feature, you’re getting the same level of end-to-end encryption. On top of this, users can’t forward or screenshot messages in secret chats, and messages can be programmed to self-destruct. Deleting a message also deletes it for everyone on the service, and users have the option to delete not just their own messages, but other users’ messages, too. It’s also worth mentioning that all chats are encrypted, even if not end-to-end encrypted. Customize the Look of Telegram Is Telegram safe to use? Pros of switching
To create your own theme, tap the three-dot button (Android) or go to Chat Themes (iOS) and choose Create new theme. Here, you can create your own look if you don't like any of the default options. On WhatsApp and other messaging apps, you can send uncompressed media by changing the media extension to something like PDF or EXE. However, on Telegram, you don’t need to take this hacky route for sending uncompressed media files. Just select your media and tap on the 3-dot menu. After that, choose “Send without compression” and that is it. How awesome is that? This single Telegram trick has saved me so much headache when sharing photos.
