Back in January we reported that Telegram is bringing support for audio calls and themes to the Android app for Telegram.
Now Telegram has officially released the support for custom themes to it’s Android app. The company says that Telegram is free and open source for stickers, bots and some third party clients.
In order to switch to a different theme, you need to go to Settings> Themes under the Telegram app. The company has already included a new Dark theme for us.
Telegram has added a new theme editor also within the app. With this you can create a theme based on your choice .
