Dear Wilfried, thank you for the mail. If format in the app setting does not help this symptom, it means the memory inside is defective which requires a physical repair and replacement in our repair center. Thank you for kind understanding.

In this case, you may need to justify and consider a physical repair. It may occur some cost. If wished, please send a message to for any inquires. Thank you
