Some time ago I have added a SD card to the device, 28.9 GB when the storage on the device was close to be full and asked new apps to be saved on the SD card. Furthermore, I moved apps from the storage on the device to the SD card. However, now – it is impossible to move more apps to the SD card though only 2.78 GB of the 28.9 GB on the SD card is used. When trying to move more apps to the SD card an error code is appearing and to try to find out how to use the error code is impossible for me. This means that the phone more or less has no value for me.
