Samsung mobile phone short message display is not complete.

Try changing the card and see if it can be used. If not, please check whether your SMS settings are correct. If there is no problem, try to reset the phone (the data of the phone will be lost, so you need to back it up in advance and try to save it on the card). If it still doesn't work, you need to go to the maintenance center. It may be a software problem. Just do a software upgrade.
