According to your description, Samsung I8552 is Android 4. 1.2 system. By default, the application program is installed in the built-in hard disk of the mobile phone, so it cannot be moved to the SD card, and the installation path cannot be changed. You can move multimedia files stored in your mobile phone to an external SD card: 1. Multimedia file: open my file-select the folder to move-hold it for a long time-move to -extsdcard. 2. If it is a picture/video shot by a camera, you can set the storage path to the SD card in advance and open the camera-settings-memory-memory card. 3. If you download files on your mobile phone, I suggest you do it in your browser.
