Delayed Texts and Incorrect Calendar Date

[userBRUNpC4Dkh]

Last 2 weeks receiving text messages hours later but when appear show time originally sent. Starting today my calendar shows a date 4 days in advance. Galaxy 21. Son's iphone is fine. What's going on?

Reset your network settings. Make sure your default calendar is the Samsung one. You'll need to repair your Bluetooth and or WiFi.
