Hey @Fizyfizz97 ,
are the phone software and all the apps up to date? If so, can you try your phone in Safe Mode to see if a third-party app is causing this to happen? To do this press and hold the Power button until you see Power Off, Restart, and Emergency. Press and hold the Power Off icon until it shows a Shield, tap the Shield and the device will restart in Safe Mode.
Safe Mode disables all third-party apps and so if the notifications start working in this mode, we can confirm it is being blocked by a third-party app. If so, you will need to locate and either uninstall or contact the app developers for a fix.
How long have you been experiencing this? Are you also able to take a look at this guide: https://www.samsung.com/uk/support/mobile-devices/how-do-i-change-the-date-and-time/ to see if this makes any difference?
It has been almost 1 year. I have updated everything. And no it did not help. I know how to change time and date but i cant since the whole section is disabled. It really annoys me because the time on my phone is not right.
Did you ever find a fix for this? I am experiencing the same thing on my Z Fold 2, the only thing I can think of that could cause this is Knox, maybe?
