Updated to Marshmallow, now GPS sucks and constantly loses fix - Galaxy Note 4 Q&A, Help & Troubleshooting

I just updated my Bell Canada SM-N910W8 Note 4 to Marshmallow 6.0.1 the other day, and ever since I did, GPS has been awful. It can see some of the satellites, but only gets a fix on 3 or 4 of them, and then quickly drops them after. Which means Google Maps will show me my location about once every 5 or 10 minutes, and just say "GPS connection lost" the rest of the time.
Are there any quick fixes for this? A better GPS.conf file or anything?

[Q] Its official my new vibrant no gps issue and signal is better.

I've tried every fix, every change and every hand position and the gps was still unacceptably slow and useless. After several phone calls to TMO I finally convinced them to send me a new phone.
I unpacked the new phone put my battery and sim card in booted it up clicked on google maps the gps flicked on and off about twice and then locked gps within 35 meters. Then I double checked the settings and use wireless carriers was unchecked.
Also my signal shows more bars. It still goes from 2 bars to 4 bars if i hold it by the top upside down but it was showing none (still worked) then 4?
This begs the question to me, is this a hardware issue? software? if it is soft why if they can fix on the later batches cant they fix for everyone?
New phone about:
model sgh-t959
firmware 2.1-update1
baseband T959UVJFD
kernel 2.6.29
the tech also told me to periodically do *#*#checkin#*#* on the dialer to be in the first people to get OTA updates when available. Anyone ever heard of this?
Thanks, i've been on this forum since my TMO pocket pc phone but this is my first post.

*#*#checkin#*#* or *#*#2432546#*#* is technically pinging google, sending your phones info... in the event you are on an outdated OS version you will be upgraded soon. It's not a waiting list, no one but Cyanogen goes first. then he gives google the go ahead to ship it out
For what it's worth, my phone was packaged on 8/19/10, and takes a long time to find GPS signal. I did both fixes, but ended up reverting back to Standalone mode to get semi-consistent results. Once it's locked in, it's very accurate.

does anyone have anything different from this? i picked up my vibrant a couple days ago, and my info is the same as this.
my gps works fine outdoors, sometimes has trouble determining location indoors. signal indoors usually shows 0-2 bars of 3g with consistent speeds, with full bars outside.
i can't complain
^^ The one I ordered from Amazon on 8/31 and got delivered yesterday has the same firmware, version etc. Today morning tested GPS on way to office and no problems. Locked satellite in 2 secs and did good job re-routing couple times when I ignored the GPS lady. I dont know if the problem starts when you use GPS more frequently. Hope not!
mind checking the GPS settings and telling us what they are? maybe some screenshots with drocap?
That's great for you but a single anecdotal data point is not an official fix validation.
I just tried *#*#2432546#*#* on my vibrant and got no results whatsoever. I have rooted with the one click root but have not installed any roms. I did do a backup rom with Rom manager and I believe it ended up with clockworkrecovery mode. I have done nothing else. Has something occured that will make it impossible for me to get the OTA? I have gotten checkin successful in the past but now nothing. Any help is greatly appreciated.
OP, this is by no means a flame but locking on with 35 meters accuracy is EXACTLY the issue with the GPS. That's 100 feet, man. Not accurate in my book. With aGPS turned off, my mt3g gets within 2-5 meters in about 20 seconds. Do a GPS stats test and see how many sats you lock on. I'll bet 1 to 3 at best. If more, post pics.
Mine works after using that fix that's been going around. Only thing is that out takes a while for the gps to lock but otherwise its fine. I think lol.
Sent from my SGH-T959 using XDA App
I got a new one, my GPS locked in 10 seconds up to five meters

[Q] GPS problems?

I purchased my Focus from AT&T when it was released on November 8th.
Since then, I've been having some issues with the GPS functionality.
For instance, yesterday I traveled around 40 miles, taking a couple hours, and the whole time the AT&T Navigator app was telling me that my GPS signal was too weak.
When I would try to use Bing maps, my "current location" was widely off - sometimes it was showing me hundreds of miles away.
This continued, even after turning the phone off/on.
Later that evening, I received 4 or 5 text messages, some that had been sent hours ago. At that point I tried AT&T Navigator and Bing maps, and both were reporting my location correctly.
What I'm trying to determine is whether the problem is a)an OS issue, b) an AT&T service issue (perhaps related to the text message delay), or c) a hardware issue.
If it's a hardware issue, I would like to get the phone replaced with another one.
Any suggestions?
Thanks.

[Q] Can't get a GPS fix

I received my current n4 as an RMA exchange. I cannot ever get turn-by-turn directions, because it never gets any better than a wifi-location fix. i downloaded gps toolbox and it shows that i'm seeing 20+ satellites, but getting zero satellite fixes. i sat my xoom down next to the n4, then reset the xoom's data. the xoom got a 6+ satellite fix in less than a minute, while the n4 still showed zero.
is it time to call google again?
more info: i have never had yahoo weather installed

[Q] GPS Problems

Edit: I actually just though of something, I updated to NF1 about 2 or 3 weeks ago and the problem started happening within the past few weeks. Does the baseband control the GPS radio also?
I know this is a problem with the Note 3 across all carriers, but it also seems to be a stock software issue. I'm on an AOSP ROM so none of that really helps me. GPS will lock on to my current location, but it won't "follow" me and it loses it's connection after about a minute and then it will sporadically update my location. I noticed this for the first time last week (I've had the phone since April/May and it has worked fine up until now) when I was trying to use Maps to get to a town a half hour away. I would open Maps and it would find my exact location and give me point to point directions but before I even moved it would say "GPS Signal Lost" and wouldn't reconnect. After about 3 or 4 reboots I finally got it to lock on and follow me. One the way back I could get it to follow me at all.
I recently started playing Ingress since I work in NYC and live right outside of it so there are a ton of players, the problem is that the stupid map won't update my location so the marker usually just stays in the same location, but will spin around depending on which way I turn. It will also occasionally update my location, for example, on Sunday I was able to play for 2.5 hours because it would actually follow me for a good amount of the time, at about the 2.5 hour mark it pretty much stopped updating. I had walked 3 blocks from where it shows me at that point I got frustrated and went home. During my time where it actually "worked" it wouldn't be that accurate, I know GPS isn't accurate down to the exact foot/inch but this would be pretty far off. I'd be standing next to portal (shown by the picture) and it would say that it was 50 or 100 meters away!
I tried to play yesterday in NYC and it wouldn't even follow me at all over the course of about 5 blocks! I got frustrated and stopped playing the game. During this time I had flashed two different AOSP ROMs and neither have fixed the issue.
GPS Status shows all the correct info, except for "waiting for GPS location....". I saw that someone mentioned checking/bending the GPS contacts but I'm not sure which ones they are and don't want to screw anything up.
Does anyone else have these issues on AOSP ROMs and if so, did you manage to fix them?
I'm currently running:
C-ROM Kang v1.6 20140816
Kernel Version: 3.4.0-gd84d543
Baseband: N900TUVUDNF1

Note 4 At&t GPS Issue
