This report is meant as an easy-to-find reference to a solution to help everyone suffering from this very annoying problem. Hopefully Telegram Team reads this and implements a permanent fix in future update.
TEMPORAL SOLUTION
Android Settings ▸ Apps ▸ [⋮] Menu ▸ Special Access ▸ Full screen alerts ▸ Telegram [ON]
⚠ This setting must be manually re-enabled after every Telegram app update.
Steps to reproduce
Turn off display.
Receive a phone call on Telegram.
Expected behavior:
Phone should ring and/or vibrate.
Display should wake up.
Full-screen alert should be displayed with options to pick up or hang up call.
Actual behavior:
✅ Phone rings and/or vibrates.
❌ Screen stays off.
❌ No alert is shown even when manually turning screen on (only a regular “Incoming call” notification is displayed, which is hidden by default and must be manually "unfolded", potentially requiring phone to be unlocked first).
Additional information:
Bug present in current and all previous Telegram versions starting from December 2023.
December (vaguely) coincides with Samsung OneUI software update and new Android version. However, I’m not sure whether bug is isolated to Samsung devices, caused by OneUI / new Android / Telegram app or something totally different.
Bug happens automatically: no settings related to notifications have been altered by users.
Re-installing Telegram app does not solve the issue (contrary, the issue will re-appear on every new app install or update)
Resetting phone to Factory Default does not solve the issue.
Conflict with other manually installed apps has been ruled out.
Other apps that can receive calls do not suffer from this bug.
Previous reports
This bug is documented on several online forums including this one. However, current reports on this issue are very hard to find due to language and translation related issues, as well and ambiguous terminology.
Hello. I'm so glad I'm not alone with this problem. Since December 2023 I have also tried everything as you described. Without success. Tried your tip and it works again now! I am so grateful that you found a solution! I hope Telegram or Google and Samsung will also find a permanent solution via an update. Thanks again!!!

I feel your pain 😅 It might not sound as a big deal, but it is an extremely annoying bug. Missed so many calls during this period, and there is not always a chance to call back (if your hands are busy, for example).
I'm glad this helped you.

Since the update yesterday, app 11.0.1, the calls are not working again. Although this setting of the tip is made. This had worked reliably for a long time. I have also noticed that the buttons are now missing when a call is in progress! After you accept the call, they disappear. Somehow there is something wrong with the behaviour of the calls.
