Secure Folder Telegram incoming calls leak caller name in the bottom lock screen panel despite hidden lock screen notification content settings.
If you want, I can also make a more polished version formatted exactly for Samsung Members with sections kept shorter.
Bug description:
On my Galaxy S26 Ultra running One UI 8.5, Telegram installed inside Secure Folder shows the caller identity on the bottom lock screen call panel during an incoming Telegram call, even when notification content is hidden.
Normal lock screen notifications are already hidden correctly, and notification details do not appear in the notification center or on the home screen. The issue happens only with the bottom lock screen incoming call panel.
Expected behavior:
When Secure Folder is locked, incoming call notifications from apps inside Secure Folder should either:
hide caller name/details and show only a generic incoming call alert, or
fully respect the lock screen “hide content” privacy settings.
Actual behavior:
The bottom lock screen call panel shows the caller/app identity, for example “CallerName” on Telegram, even though privacy settings are configured to hide notification content.
Device / software:
Device: Galaxy S26 Ultra
OS / UI: One UI 8.5
App: Telegram inside Secure Folder
Steps to reproduce:
Install Telegram inside Secure Folder
Lock Secure Folder
Set lock screen notifications to hide content
Ensure normal notification details are hidden on lock screen
Receive an incoming Telegram call to the Telegram app inside Secure Folder
Observe the bottom lock screen incoming call panel
Result:
Caller identity is visible in the bottom lock screen panel.
Troubleshooting already tried:
Disabled lock screen notification display for Telegram
Disabled Telegram notification categories including internal call notifications
Disabled all available Now Bar / live notification toggles
Verified that normal notifications remain hidden correctly
Issue still persists only for the bottom incoming call panel
Impact:
This is a privacy issue because Secure Folder app activity exposes caller identity on the lock screen even when content-hiding settings are enabled.
