Why is gti8552 Samsung mobile phone contact alphabet missing letters?

According to your description, I suggest you try the following methods:

1. It is recommended to go to Settings-Application Manager-All-Contacts-and try to clear the data.

2. Check whether software programs such as mobile phone security guards are installed in the mobile phone. If there is an attempt to uninstall, please check whether the installed third-party software is incompatible or caused by software restrictions.

3. Try using another SIM card.

4. Back up the important data on the mobile phone and try to restore the factory settings.

If the problem still exists, it is recommended that you send your mobile phone to the nearest service center for testing.
