Huawei watches suddenly go black, but they can still be used normally.

Low power, software problems, hardware problems, etc.

1, low battery: the watch has no battery or low battery, resulting in a black screen. Please connect the watch to the charging base to charge it, and then try to turn it on.

2. Software problem: There is something wrong with the watch software, resulting in a black screen. This is due to system errors, application conflicts or other software failures. You can restart the watch or update the software to fix the existing problems.

3, hardware problems: watch hardware failure, resulting in a black screen. This includes screen connection problems, battery problems or other hardware failures. Software update is invalid. Send the watch to a professional maintenance point for inspection and maintenance.
