We apologize for any inconvenience this may cause.

If your device is inserted into the memory card, it will be reflected in the fuselage menu (System Settings - Storage) after normal recognition, if it cannot be reflected normally, please use the following steps to perform a simple troubleshooting attempt to solve the problem:

1. It is recommended that you shut down and restart your device and try it.

1.Your device supports a maximum of 32G micro SD card (TF card), it is recommended that you check whether the memory card can be used here;

2.If the memory card is not in good contact, it is recommended that you shut down and re-insert the memory card to see if it can be used normally.

3.It is recommended that you try to format the memory card again in FAT32 format.

4.If the memory card itself is abnormal or compatible, it is recommended that you use other memory cards for comparison, if other memory cards can be recognized, it is recommended that you replace the memory card.

If the internal and external memory card still cannot be displayed normally after the factory reset operation, it cannot be ruled out that it is caused by the failure of the body card slot or other components, we recommend that you take the time to go to a nearby Lenovo authorized repair station for specific testing and processing.

Because consumers like to will"Built-in storage"with"Internal memory"Both are referred to as memory, so the two are often confused, so industry professionals have coined a new term to avoid misunderstanding"Storage", to represent"Internal memory", with"Built-in storage"Make a distinction.

In computer terminology, RAM belongs to random memory, also called internal memory, referred to as memory, mobile phones and other mobile terminals are the same as personal computers, but also belong to computers, for memory, the name and concept should be the same, all belong to RAM.

While"Built-in storage space (ROM)."In a narrow sense, it refers to the storage space built into mobile terminals such as mobile phones and tablets, which is used to store documents or various documents, and often uses built-in SD cards and MMC cards.
