Dear friend,
Thanks for your message. Sincerely sorry for the inconvenience caused to you! No worry, I'm here to help you.
When you insall the memory card, you may need to press the memory card with a little power. Then the memory card will be inserted into the TF card slot successfully.
If you not mind, could you please try it again?
Besides, have you tried the item with different memory cards? Will the item function well?
Thanks for your understanding!
Coco:)
