@Schnuupi: Are you using the USB-C cable that came packaged with the phone? If so, do you have access to another compatible cable, and does the issue persist with the alternative option? If it does, I recommend heading to samsung.com > Scroll to the bottom of the page > Contact us, and get in touch via your preferred contact method, and an advisor will be able to arrange for the device to be inspected by an authorised engineer under warranty. If the issue is software or hardware related, and your Z Fold3 is under 24 months old, then the service will be free of charge. If the engineer identifies physical or liquid damage, which is not covered by our standard warranty, then a charge will be applicable to cover the cost of the service and any necessary repairs.
