6.5" Phablet that works!

[lookylooky]

I'm familiar with all of the above methods but with certain models it's just no use. Yes it's the same GPS but the most important thing you mentioned is the last part about the GPS antenna. Poorly designed, placed GPS antenna hardware will cause all sorts of problems.
I believe the GPS portion of the newer Mediatek SoCs works just fine, and that the hardware is the true problem. There are many threads sound the web about the zopo zp998 gps. The zopo zp990 was also beyond help.
I've found several models recently that will lock when being tested with apps but when you try to actually use them they aren't very good.
Careful or your car will end up inside a shopping mall or underwater....lol
