After the update to iodeOS 4.0 on my Fairphone 4 the GPS takes very long to get a good lock. Sometimes minutes, however when it finally locks it works fine. This leads me to think there might be an issue with A-GPS ?
Hi, there might be an A-GPS issue indeed. You can check with gpstest as @AlphaElwedritsch suggests: if you don’t quickly see a list of satellites, it might be the case. We will make some tests on or side too.
I use my (Magic Earth) navigation daily to avoid traffic jams. For a few weeks now (since the 4.0 update) i experience this slow locking daily, so it is not a one off issue.
I just tried outdoor in sunny weather and clear sky with the GPStest app,
The first lock took about 45sec and then it lost the lock again a few times before it became stable.
The list of satellites starts short and then builds up gradually.
