Hello Chica10, welcome to the Samsung Community! I understand your concerns about not being able to view your unread messages. Are you talking about your text messages are not showing in the notification bar, where you are able to pull down from the top to view? You can prioritize and streamline app alerts by changing which apps send notifications and how notifications alert you. To find this, swipe down from the top of the screen, and then tap the Settings icon. Tap Notifications, then tap Notification pop-up style, and then select a pop-up style. You can choose Brief or Detailed, and then customize the notifications as desired. If you are still not able to view your notifications then I would recommend that you clear the cache partition on your device: power off your device, hold down the volume up and power buttons together at the same time until the Samsung Logo appears and then release the power button, select clear cache partition and reboot your device as normal.
Please let me know if you need further assistance.
