How to show all notifications on One UI lock screens Open the Settings app (gear icon). Scroll down and tap Lock screen.
Scroll down and tap Notifications.
Tap View style. Tap Detailed.
If the toggle next to Hide content is turned on (lit up), tap Hide content to toggle it off.
Drag the Transparency slider left or right to give your notifications a clear, opaque, or white background with your desired transparency. I personally prefer fully transparent notifications because they light up fewer pixels on a black wallpaper.If the toggle next to Auto-reverse text color is turned off (dark), tap Auto-reverse text color to toggle it on. This will allow the system to automatically reverse your notifications to white text against dark wallpapers and keep things readable.
This seems to be an issue. Does your phone vibrate for such notifications? Also does your phone wake up if it is in sound mode? Please check correctly.
