Samsung Galaxy S23 Ultra. Getting late messages. Getting late notifications even after I already saw the messages . Never have a reliable data signal .
Note 10+ here with same issue. Does happen worse if on WiFi. I think it is a carrier issue since messages and/or notifications are sent through the network via the carrier and are not device-specific.
You can also reset the app preferences. Here are the steps : Go to Settings >> Apps >> Tap on three dots on the top right >> Reset app preferences >> Reset.
Another step is to reset the Network settings: Go to Settings > General Management > Reset > Reset Network Settings (Please note that this will reset Wi-Fi, Cellular data, and Bluetooth settings which means you will have to input your Wi-Fi credentials again.
Additionally, we recommend disconnecting from any VPNs you have connected to, and testing the phone.
Please note: mobile data, text, and calls are all services provided by the carriers. If there are concerns with any of these functions, you will need to follow up with your service provider for additional assistance.
If you continue to experience delayed notifications or texts, or are not receiving any notifications, we recommend having the phone evaluated by an authorized service center.
