my signal always turning off on my p9lite?

I have the latest emui of huawei, still the bug is there a little. Compared when not updated. Do anybody experience this too?

P9lite status bar

Hi, is it possible to have the stock status bar, without rooting the phone?

The emui statusbar is incompatible with some application as cpu stats, infact the cpu status is not displayed and the phone displays the default static icon of the program.

Could you help me
