I've tried several times but after a while, the photos app stops and it does not work. I can only import photos but no videos. Why is that?
Next time please less info, then you can help even better
Import from where? From the cellphone?
Connect it as a disk, you can select, go to the appropriate folder and copy as from a stick the files.
Android folder: internal memory or memory card → DCIM → Camera
Is something more inaccurate?
Who should answer you SENSEFULLY?
