From Jarltech Europe GmbH:
The Jarltech Service app makes accessing warranty and service data pertinent to defective hardware easier. Using the serial number and the imprinted barcode, find out if the device is eligible for a warranty claim, and if the device is covered by any additional services (plus if they are still active).Simply scan the barcode of the corresponding device. All available information will immediately be reported on your display (with the conditions that your smartphone has an active internet connection and that the device was purchased at Jarltech).The report contains all relevant information necessary for arranging quick and simple repairs or device replacements. It promises you non-bureaucratic assistance and quick processing by the responsible repair centers listed under the service addresses. You may also directly and comfortably forward all the data from the app to an e-mail, in order to prepare the shipment in a timely fashion.Tip: While scanning hold your smartphone as still as possible and point it close to the barcode to register the information.
