GPSTest

★★★★★ I just started applying this, but have some suggestions. I want the highest-accuracies that a dual frequency GPS smartphone can achieve. First, a feature that causes the software to only use satellites that have dual-frequency signals? Would that help? Second, increase the displayed resolution (in each format) to 3 cm or smaller. Third, add an averaging function. Fourth, eventually RINEX support, for post-processing.

★★★★★ I've been playing with a lot of GNSS application lately, primarily with the NMEA sentences they emit. This app (and the "GNSS Logger" to which I suspect it is related) do a great job - but I have found that both apps randomly stop - but then restart - logging of data. This probably wouldn't matter much if one weren't trying to build track logs for comparison with other GPS receivers (Garmin ones in my case) but it caused my to remove one star from what would otherwise have been a perfect score.

★★☆☆☆ Why this app need access to photos and storage??

★★☆☆☆ This app is not latest OS updates. His targeted API is Android 12.

★★☆☆☆ Even enabling location it always pops the message... GPS is disabled

★★☆☆☆ It drained my battery despite the fact it was only supposed to be using location services while the app was active.
