Huawei enjoys 9plusQQ, and the indicator light is not on. How to solve it?

1. This may be caused by a software conflict. Let's see if only qq or other software notifications will happen. If you only have qq, you can uninstall qq and go to the app store to download and install qq again.

2. If it used to work, but it doesn't work now, consider whether there is something wrong with the system. You can refresh the machine and observe it again. If it doesn't light up after brushing, there may be something wrong with the hardware.

3. If there is something wrong with the hardware, take it to a professional mobile phone repair point for inspection and maintenance.

4. If all the above attempts still fail, it is recommended to change your mobile phone.
