My Galaxy S20 is not receiving all text messages, I have to reboot phone then 3-4 contacts messages will come in from the last week all at once. This expensive phone seems to be a POS, very disappointed I went with this phone. Any suggestions on how to fix the issue.
From settings > General management > Reset Network Settings
FYI: This will uninstall your wifi & Bluetooth devices. Afterwards you will need to reinstall your them
If that does work, I would recommend you contact your service provider & replace your SIM card
