Huawei Glory play drop-down notification bar cannot be displayed.

In this case, you think there is something wrong with the theme.

I suggest you find the theme option of your mobile phone and try another theme. First of all, I suspect that there is something wrong with the theme background of your mobile phone, which leads to the same color of the display screen and the background, so that you can't see the difference.

If it still doesn't work, it may be a system bug. There are only two ways to try this problem.

The first is to find the phone settings, find the recovery options, and then talk about the factory settings of the phone.

The second method is a little more complicated, that is, download the ROM package of the brush machine from the mobile phone official website and try to brush the machine once according to the prompts.

It is estimated that these two methods can solve this problem. If you really can't solve it, just ask me and I'll get back to you when I see it.

But I think there is an 80-90% chance that it can be solved.

Finally, good luck!
