GPS will never work again on the Note2, unless Samsung does something about it (which they won't). No matter which ROM, the binary driver is broken and doesn't work properly anymore since 07.04.2019.

Yes it can be made to work

Nope. Unless you have access to Broadcom's SDK with the source for "gpsd".

You don't need the sources to make it work. Yes it would be better to have the sources but they are not required. If I would have wanted I can easily make a nougat build that has gps rollover fixed and gps works

How can you fix gpsd without the sources? Reverse engineering?

By changing the Android gps implementation. For GPS rollover you just need to add the days

thanks @ComicoX ,
we don't have fully working oreo or pie rom. But we have only 2 stable nougat roms Crdroid and Aicp. Please add fix or help fixing for Gps Rollover (WNRO) on this roms.
Maybe @treysis can help you too.

I think it would be the HERO who could solve this problem.

thanks in advance.

No, that is the problem with the Note2: gpsd loses satfix. This happens also on Stock ROM. Not only the date is wrong. E.g. S3 uses similar gpsd (also Broadcom, but previous chip) and also outputs wrong time, but it has no problem with satfix. You can't correct satfix problem without changing gpsd. And if you have no satfix, you also have no gps-date, so you can't add any days.

To fix on a satellite the GPS chipsets and the satellite need to have the same time. If they don't agree on the time then it will not connect. The hole magic from GPS it's made by counting the time difference between the satellite and the device

GNSS works much more complicated. Also, relative time is enough. The date/timestamp is submitted as payload (simplified), it's not needed for satfix. Without satfix, you will get neither date/time, nor location.

And this is the problem: gpsd on Note2 is faulty since WNRO. If you can't fix gpsd, you can't make GPS work on Note2. Like I said, S3 also has wrong date in NMEA sentences, but it has no problem with satfix.
