My Huawei Watch GT 2 Classic Edition works without any problems, the warranty has expired. However, the touch display has not been responding reliably for some time now. "Normal" sized buttons work, but small ones no longer do. By small function buttons I mean, for example, those used to set the alarm clock. I can no longer deactivate a set alarm clock. I have to delete this alarm clock to deactivate it. It is also no longer possible to set the days on which the alarm clock should be active. Conclusion: No function for small buttons, normal function for large buttons. I have already reset the clock, unfortunately without success. Does anyone know the problem? Is there a trick or is this a defect that cannot be repaired? Thank you
