Just like Signal, Telegram has the tendency to annoy you with notifications every time someone from your contact list joins the messaging app. We’ll show you how to disable these pesky notifications on Telegram.
On Telegram for Android, follow these steps to stop receiving notifications whenever one of your contacts joins the app.
Open Telegram and tap the three-line menu icon in the top-left corner.
Here, select “Notifications and Sounds.”
On this page, scroll down to the Events subhead and toggle off “Contact Joined Telegram.”
Stop New Chats from Appearing in Telegram When Your Contacts Join
Whenever new contacts join Telegram, you will automatically find a new chat with the contact in the mobile app. You can stop this as well, but the method may be a bit extreme for some people. It requires you to use Telegram without sharing your contacts.
Before you do that, remember that this method makes it difficult to start new chats in Telegram. If you deny the app access to contacts, you might have to resort to searching for people with their username instead of their phone number. If people haven’t set a username—or if they have hidden their number in Telegram—you may not be able to find them.
