There are reports about government acquiring software for "breaching encrypted-messaging applications such as #Telegram and #Signal."
They most likely talk not about breaking the encryption or the apps, but about connecting your phone via USB to a machine trying to hack into your phone's operating system (iOS, Android).
So, changing the app makes no difference. Stick with your encrypted messenger (and Telegram is not one of them, despite their claims)
