Cloud access Lock Your Conversations Like many communication apps, Telegram includes chatbots. Bots add useful functions both on their own and into your chats; they can do everything from checking the weather to playing games.

Tap your profile picture here to see everything you've uploaded in the past. You can scroll across them; tap the Set as Main Photo option that appears on the top-right menu (as three dots on Android or Edit on iPhone) to set an older image as your current profile picture. Premium Chat Management Another security feature that adds usability is usernames. Instead of giving people your phone number, you can simply give them your username. This gives you better control over what information is out there, and how people can contact you in the future. By subscribing to Telegram Premium, users unlock doubled limits, 4 GB file uploads, faster downloads, exclusive stickers and reactions, improved chat management – and a whole lot more.

To do this, head over to Telegram’s settings by sliding over the hamburger menu from the left of the app. Here, choose ‘Settings’ and then click on ‘Chat Settings’. In this menu, you will see a number of themes and colour options to choose from. Further, you can also change the curve on message boxes and font size. Telegram supports two layers of secure encryption. Cloud Chats use server-client encryption while Secret Chats use an additional layer of client-client encryption. All content is encrypted in the same way — be it media, text, or files. 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. Telegram Attachment Options

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. In fact, Telegram has solved the issue with its Secret Chat feature.
