To preview a chat, simply press and hold its profile picture in your chat list. Another great option in groups or channels is being able to pin messages. Tap a message and choose Pin to keep it at the top of the chat, where everyone can easily reference it. There are many astonishing features that set Telegram messenger apart from other messaging services. For instance, you can coordinate groups of up to 200,000 members, send documents of any type, destruct your messages with a timer, or even build your own tools on their API.
Just press and hold on the message you want to change and then tap the “edit” button. From there, you can modify the message and resend it. Telegram will put an “edited” label on the message to let recipients know of the update. Open Telegram chat While all Telegram chats are client-server encrypted, default chats are still stored on Telegram's servers. This conveniently allows you to access your messages on multiple devices, but it might raise privacy concerns. 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.
Whether you no longer want to let redundant chats clutter the precious storage of your device or wish to shield your personal chats, the auto-delete timer is for you. When you set an auto-delete timer for a specific Telegram chat, all of its content including images, videos, and documents are automatically deleted after the timer expires. Dozens of stickers now have impressive full-screen animations, which Premium users can send in any chat to add extra emotion and expressive effects that are visible for all users. This premium sticker collection will be updated monthly by Telegram artists. To use a proxy server in Telegram, open Settings > Data and Storage > Proxy Settings.
