Ya. By default Google Maps not shown in the list as it is already Ignore Optimization.
Other 2 solution is:
1. Set Google Maps to "Don't close" via Lock Screen clean up.
2. Get GPS Locker via

Was using the GPS just now for a while and it's working...
Will observe a few more days and give feedback

I'm using Huawei P9 for almost 2 years. In my experience, GPS signal with this device is terrible.
After searching Google and XDA I've found that other people also had the same issue with this model. I tried the following steps, works for awhile only.
The steps are:
- Go to "Advance Settings".
- then go to "Location Services"
- Press the 3 dot (on the top right) and select "Scan settings".
- Disable/unselect the Wi-Fi scanning (and "Bluetooth scanning")
I think there is no solution for this phone

My Wi-Fi and Bluetooth scanning is off all the time...tried this method...doesn't work last time..
Yea...saw some comment they say this phone use cheap GPS chip
