Please welcome Samsung I900 mobile phone master.

For the setting of SMS ringtone, after finding the information: new SMS/new MMS/new email, open the drop-down box for setting/sound and notification/notification, check the corresponding options and find your favorite in the drop-down box.

Besides, ringtones are usually in my files. In order to save the memory of mobile phone, you can create a new folder in my storage or memory card, named My Docunments, and put the ringtone in it.

About the shortcut icon on the left, it should be TouchWiz of Samsung i900. This plug-in is pinned and cannot be added. LZ can try to restore the factory settings. Please make a backup.

To solve this problem, it is recommended to use other desktop software, such as spb phone case. There are many more, very beautiful and easy to operate. Please go to the related posts of mobile phone empire to download and learn to use.

I hope it helps.
