What files can be deleted in Samsung mobile phone system?

Dear Samsung users, according to your description, Samsung Android phones have some network operator software and third-party software programs built in. Because the permissions of the built-in programs in the mobile phone factory are fixed, in order to protect the safe use of your mobile phone functions, it is not recommended that you use ROOT or other software to change the mobile phone program to delete the built-in programs. Some built-in software can be uninstalled. It is recommended that you go to Application-Menu-Uninstall. If the software shows a red minus sign in the upper right corner, you can uninstall the software. Samsung knows to provide you with high-quality solutions and answer your questions attentively, hoping to get your satisfactory evaluation.
