S5 If the number in the short message content is not blue, you can't operate, such as making phone calls, copying and storing contacts. Thank you. . .

According to your description, in order to eliminate the causes caused by third-party software, it is recommended that you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings (Settings-Reset-Restore Factory Settings). If the fault still exists, I suggest you take the three-guarantee certificate of your mobile phone and send it to the nearest Samsung service center for engineers to check the machine.
