[Galaxy Note 4 Q&A, Help & Troubleshooting] zenorth:
thank you butternutty for digging all these gps related details. i'm also waiting for some more in-depth reviews on that matter. just to confirm your thoughts on past devices, my experience with the predecessors weren't pleasing.

during 6months i checked the accuracy of a note 1 & a note3 next to each other w/o a-gps (as you would use when travelling abroad and avoiding roaming charges) with the following apps: gps test+ & gps status. roughly 3 times a week while travelling by car between 1 to 3hrs. the note 3 (qualcomm) was far worse than the note1. loosing fixes and badly inaccurate (12-17m in average) within cities, out on the open and anything inbetween, as well as in different weather scenarios i.e cloud coverage. i used 5 different note 3 devices during that time period and 2 note1. btw, i also checked it on a bike, walking, as well as on different continents and have used "professional" gps devices before. these results plus the annoying compass calibration issue (after each start, so basically every morning) resulted in me selling the note3.

it's a pitty, because i like & use the stylus on the note line. thus i thought the note4 would cure some of these problems. reading in the forums the experience of early adopters, it seems, that we're facing again compass calibration issues after each start (not an issue on the note1) and the gps w/o a-gps doesn't seem to be very strong or is on par with the note3. so basically no changes as you stated.

depending on which region you live, you get the qualcomm chip and have to pay overprice to get the arguably better spec'd n910c with exynos because it seems it uses hopefully a better broadcom gps, cat6 bands, (if i read correctly) a wolfson chip a/d sound converter, uses probably (i'm not sure-just stating the experience of others in this forum) an isocell cam with pdaf and therefore faster autofocus like the s5 and not what's found on the qualcomm which uses sony's imx240 chip and it's contrast detection. moving along comes the issue with lollipop & 64bit, which should be "available" on the exymos version in 64bit if sammy releases it or "opens" it from 32 to 64bit. even though the discussion on 3gb vs 4gb ram using lollipop in 64bit will follow. all this puts the buyer in a situation in which he's uncertain if he got the "right" note4 version.

sammy, quo vadis on the note line? imho they should start concentrating on quality sensors instead of adding new ones. is qualcomm's 810 the answer? will it be rootable? wait another year? every year and before the launch i fall for all the hype of what we should expect specwise/ supposed leaks. once the device is officially introduced, we supposedly didn't get this or that specific because time or manufacturing process or whatever were an issue. but by the end of the day - as in this case with the note4- i'm a little disappointed that such and such item didn't make it in the final draft (e.g. ip 68).

hope to read more gps real life experiences of either qualcomm or exynos note4 users here.

p.s.: reading thru the posts here, i hope it's clear, that i'm not talking/writing about car navigation software (e.g. tomtom/sygic) which corrects via likelihood calculation your position and puts you on the next available street and therefore doesn't indicate your real position but your "expected" position in accordance to the navigational map/grid and where you "should" be.
