Huawei Watch GT 4 Screen Keeps Failing After Multiple Repairs

On September 7, 2024, I purchased a Huawei Watch GT 4 (41mm, white leather strap) from MediaMarkt through N11. Approximately one year after the purchase, the watch began experiencing several display issues, including screen fading, excessive brightness, touchscreen failure, and eventually a completely dead screen. The device was received by the authorized service center on October 22, 2025, and was returned to me on October 23 after I was informed that repairs had been completed. However, less than a month later, the exact same problems occurred again, so I sent the watch back for service on November 14. On November 20, the device was returned to me along with a service report stating that the screen, motherboard, and housing (including the battery, sensors, microphone, and speaker) had been replaced and that the device had successfully passed its final inspection. Both repair procedures were covered under warranty. Nearly a year passed after these repairs, but in September 2026, the exact same issues appeared once again, and this time the screen stopped working completely. I sent the watch back to the service center. When a service representative called, I was unable to answer the phone at that moment, but we subsequently communicated through text messages. This time, I was quoted a repair fee of $148 for replacing the screen, housing, and motherboard. I was also informed that the warranty had expired. However, when Huawei customer service contacted me afterward, I learned that the reason given for the refusal to cover the repair was allegedly "user damage" caused by water entering the device. I understand that the warranty period has expired, but I have experienced the exact same malfunction three times within approximately two years. If this had genuinely been caused by user negligence, the previous repairs should not have been covered under warranty either. Since the same malfunction keeps recurring despite multiple repairs, I believe there may be a serious manufacturing defect with this product. If I had not previously held off on sending the watch for service because I could not determine whether the issue was related to the display dial or the same recurring malfunction, I would have sent it back again before the warranty expired. Experiencing the same problem three times is simply unacceptable, and I have completely lost confidence that another repair would permanently resolve the issue. At this point, I am not requesting another paid repair or replacement of individual components. Instead, I am seeking a fair resolution and compensation for the inconvenience and repeated failures I have experienced. I request a permanent solution that addresses these recurring defects and protects my rights as a consumer. Ideally, I would like a refund or a replacement of the device. If this matter cannot be resolved satisfactorily, I would also like to make it clear that I intend to file a complaint with the Consumer Arbitration Committee.
