PinePhone RTL8723CS automatic test fail and WiFi problem

[pjsf]

I run automated tests RTL8723CS is failing.
https://wiki.pine64.org/index.php/PinePhone

If RTL8723CS is failing:
"make sure there is Wifi router around 5 meter area when perform this test, the Wifi test function sniff for SSID to determine test result during autotest. The Wifi can fail if the battery power is too low. "

I tried with battery full and charger on but still automatic tests fail and there should be Wifi signals around.

And I have not got WiFi working with Ubports or Manjaro Alpha3.

Any one else having this problem?
Any ideas how to get it to work?

Or is the HW just faulty?

I think I remember someone else with the same problem got it to work by flicking the privacy switches from off to on and back again, YMMV.
