[ONE Android Development] ulipo:
Finally I managed to try another rom, based on an AOSP source tree, where the GPS is working waaaay better than on Lineage. Obviously that rom lacks a lot of TugaPower and I want to go back to this one, but for me GPS is essential and I want to help resolve the issue.

I noticed that gps.conf in that rom is mostly commented out, if someone want to try to use that conf in TugaPower to see if it makes any difference, here it is:
