My Huawei P20 Pro can't find satellites.

[Android Central Question]

Bought my P20 Pro from Amazon 1 month ago. At first, the GPS function was ok, but after installing some apps it stopped working. Have tried restarting, erasing all data, and countless apps to try to fix it. Even took it to Huawei support where they can't seem to find a problem. When I try to use Waze or Google maps, the legend "no GPS signal, showing approximate location".
Read on this forum of similar problems with Samsung note. Any idea how to fix this? When I downloaded a satellite search, no satellite shows up. I'm going crazy!

Still me. This issue arises while I'm outside as well. It has nothing to do with being inside.
