Is my Tilt (GPS) possessed???

I've been using my at&t tilt with tomtom flawlessly since I purchased it earlier this year. A few weeks back while visiting the cemetary (paying respect to some past relatives), I tried using tomtom to help plot down where some of the graves were located.
After waiting a few minutes for the gps to acquire a signal, it eventually got 1 bar, but showed my location about 220+ km(~150 miles) off! It would also show my travelling speed to be incredibly fast (like the speed of a plane), but would eventually slow down to drving speed and it would show me driving along a road... I never watched it long enough to see where exactly it was going (or where it was going to end!?)
Keep in mind this is in a cemetary, no where near any obstructing trees or buildings, nothing but blue sky. I tried turning the radio off (airplane mode) and back on a few times, reloading tomtom etc, but everytime it would show the same thing, starting back somewhere flying really fast...
So geez, I thought that was kinda eerie.. so later that day (and away from the cemetary) I tried it again and it seemed to work OK. But lately I've noticed this intermittent behaviour again, and the only resolution I've found was to simply do a soft-reset and everything would appear to work ok. Has anyone else had this similar issue?
Is it simply:
a) a gimped up qualcomm chipset, or
b) a bug in the OS/driver/stack, or
c) or is my phone posessed???!

Wifi causing trouble with O2X

I know that there are random reboot/freeze issues with this phone but I have noticed that my issue seems a bit different.
My phone goes into reboot loops and freezing only when I turn on the WiFi. I'm patiently waiting for the LG "update fix" but wanted some advice from the experts.
Im in afghanistan and only have until next week to return the phone. If it is a software issue then I dont mind waiting but if it is hardware then I dont want to get stuck with a 600.00 paperweight.
I know Im shooting in the dark but I really would appreciate some thoughts or advice.
BTW - I have had the same issues on custom ROM's and stock ROM's. I think I damn near flashed the phone with every possible thing i found on this board, haha.

well it seems like my issue is still isolated to wiFi. The phone has almost no reboots and very little freezes when WiFi is off. any ideas on if this is a possible hardware or software issue?

was it with every ROM you tried the same ?

It happens with every rom but I hate to get my hopes up but it seems to have start happening not as often. right now Im using this
[ROM][21/4-11]TK-ROM Vanilla + LG = true. v0.5.7 (Fr12)
couple of hours so far and it is better but not perfect.

Mine has just recently been randomly rebooting but was fine when I first got it. It never seems to reboot when I'm stationary only when I'm in the car or riding my bike. Twice it happened in the same location on the drive home from work which got me thinking it could be location related. The gps wasn't active at the time so I tried turning off wifi/cell tower location in the options. I managed a two hour bike ride with no reboots today whilst using gps tracking and listening to music. Yesterday the phone wouldn't go more than 10 minutes without rebooting.
Could it be bad location data in some mobile phone masts are making the phone crash due to a bug in the software?

GPS navigation issues on two devices now

I got my original Note 4 last Sunday. Since I use GPS navigation quite often, it is always one of the first things I check out when getting a new device. I found that it didn't hold a lock for long, it takes a long time to get a lock again, and when it does lock it's not accurate at all. I got an exchange today, and the same exact thing is happening with my new unit. A friend told me this would be the best place to come for help. She mentioned that rooting and custom romming might be the fix. I haven't rooted since my MyTouch 4G, and I've never used a rom. Can I get some help with that?
Also, I've tried waze instead of Google maps and that didn't help. And yes, high accuracy is turned on.
Thanks in advance!

Bump - any advice? On a different forum, someone mentioned downloading a GPS fix app from the Play Store. I did that, and I'll check it out on the way home from work. But ultimately I'd like a device with strong GPS natively. I'll try to exchange it one more time. I find it really weird that I'm the only one that seems to be having these problems!

Yes, on both devices.

Are you the same penguin from the a/c forums?
Sorry to hear you're still having gps issues with your replacement phone. Silly question, but is high accuracy mode selected in the location settings? Is wifi enabled?
Have you tried installing GPS Status? How many satellites can you lock onto?

Yep, I'm the very same penguin . High accuracy mode is indeed enabled. I haven't tried it with wifi enabled, I usually disable it when I leave home to conserve battery life. I'll try keeping it enabled on my commute home tonight. I've installed GPS status and it locks on to like 13ish out of 20ish satellites (it fluctuates a bit) when I'm stationary so that's not a problem. I haven't tried seeing how many lock on when I'm driving since I don't want to fiddle with my phone that much when I'm on the road. I'm still trying to get one more replacement before my 14 days are up, but the day is approaching quickly, and none of the 7 or 8 stores in my immediate area ever have any in stock! I call every other day and I'm sure I'm driving the reps crazy lol.

I've had this same issue with my first Note 4 on TMo but replaced it last week and havent had any issues besides very occasionally having a slight hang after making a turn and the GPS not registering it for a few hundred feet.
On my first note 4 it would CONSTANTLY lose GPS signal and be wildly inaccurate (not recognizing my turns or the proper facing direction) but hopefully *knock on wood* its been fixed with my new phone. I know you've already exchanged it but...
If you find a fix, please post it here just in case

I had the same problem with the GPS, it was working only on wifi but not with the phone data. But after a full flash it is working fine again. Also, it was very laggy since the first day.

I had a thread around here for similar GPS issue.
I actually got a PM from someone called SamsungSupport.
Anyway I think this is a compass calibration issue.
I installed the GPS Status app and recalibrated the compass.
The next time I used it (yesterday), I didn't have any issues.
I don't know if it has resolved the problem and I'll keep monitoring it whenever I use GPS.

I got my second replacement yesterday, and it's even worse than my initial replacement!! It's as bad as my first device.
I chatted t-mo customer care today and they were of no help. They kept advising me to do the same troubleshooting issues I've already done. Then, I chatted Samsung care and the rep was A LOT more helpful than the previous Samsung rep I spoke with. Samsung has a remote app that you can download from the Play Store, and the Samsung rep can remote into your device and see what you're seeing. We couldn't do much at the time since I'm at work, but I'm set to chat them back right before I leave work. They're going to remote in with me and actually see the issue that I'm having while driving. HOPEFULLY a fix will come out of all this!!

Bump. I'm on my FOURTH replacement now, same issues. What is going on?? So far, I've:
Recalibrated the compass
Tightened the screws underneath the battery door (they seemed pretty tight anyway)
Samsung support reps haven't been able to work with me using the Smart Tutor (remote into my phone to see/manipulate what's on my screen) app. They always disconnect the session before I get on the road, or maybe the session just drops.
Factory resets
Clearing the cache
I got my firmware reflashed at a Samsung kiosk at Best Buy
Make sure high accuracy mode is enabled (these days I never take it off since I'm always fiddling with my GPS)
Tried a number of gps fix apps in the play store
They want me to send in the phone for repair, but I have this nagging feeling that they're going to turn it on, see that gps can indeed get a lock, and send it back. Plus, there's no guarantee that T-Mobile will have a smartphone loaner phone, since they say that those phones keep disappearing because there's only a $50 deposit, so people just take the phones (this is why we can't have nice things). Since no one else is reporting these issues, it's doubtful that Samsung is working on a software fix for it. I'm really REALLY enjoying this phone otherwise, but I NEED gps to work!!

Samsung Note 4 Issue with Waze
I just upgraded from the Note 3 to the Note 4 two days ago and I have the same issue. It took me a few hours but I figured what they have done. They have program the Note 4 for totally hands free driving and if you want to use a GPS program it will be the one they have. You have to activate CAR MODE and you will see and hear your Waze in the background come on line and start to work correctly. Then if you close their program quickly, you will see Waze running correctly for about 5 seconds and the go back to acting up without GPS signal. The GPS signal with high accuracy is tied to the CAR MODE.

TMOBILE will never offer a smartphone loaner as per policy. GPS works fine not sure what ur doing

The GPS on my LG G4 is horrendous

So I've had my G4 for a couple months now, and I've noticed the GPS is literally almost worthless. My location is set to on and high accuracy. My usual routine is to look up the route before I leave my driveway like any normal person. The GPS locks on after a while, and when I start driving is the problem. It either won't update to my moving position (I live in Pittsburgh and T-Mobile's coverage is pretty good) and will frequently freeze. Or it will randomly start locking onto random locations around my area but not on my car. This is incredibly frustrating obviously because I absolutely need my GPS to work. Does this sound like a hardware problem and how do I prove it to T-Mobile to get a replacement device?

With a clear sky, my GPS is amazing. But with heavy cloud cover I cannot get a decent lock.
Seems the AGPS (tower based location) is worse on this than any device before. Even with Wi-Fi on.

Came here to post the same thing.
For some reason, over the last few weeks, my gps started going bonkers for no reason. It will work just fine for 20 min and then all of a sudden it will keep thinking that I am 70 feet west of where I really am. So if I'm driving south on the highway, it thinks I'm driving parallel to the highway but 70 feet to the right of the highway. So whenever there is another road nearby, Google Maps thinks I'm on that road and tries to reroute me to get back on the highway. If there is no other road nearby, Maps will correct my location to the highway. It is really frustrating because it becomes useless with intersecting roads and constant erroneous rerouting. The arrow keep jumping back and forth and the app is giving me false rerouting instructions non-stop. Not to mention the map keeps rotating around because it gets confused about which direction I'm headed. Super confusing.
Once I reboot the phone, everything goes back to normal and the gps is once again super accurate (until it happens again).
This issue happens every other day or so.
I did update to 10N as well as rooting and putting TWRP on it a months ago (around the same time these issues started). Not sure if the bug was introduced with 10N or if it's related to the root and TWRP (doubt it).
I started really hating this phone as I keep getting lost while driving.

Is this the same type of GPS issue on Samsung flagships? Those require opening up the phone and lifting up the GPS leaf pins.

Have you tried using Device Only mode? I noticed that once I did that accuracy went to 100% while driving.
I think it's a software issue that shows up when the phone is not using the GPS and instead relying on WiFi and Cell for location.

You know, you might be onto something about the assisted gps part (cell and wifi)
Shortly after I posted the message, I started using this app called GPS Status & Toolbox. It has a feature of clearing and updating the assistance data (A-GPS) which it can automatically do once a day. Since I started using it, I haven't had the issue.
It's possible that there is a software glitch regarding cell and wifi assist

Los Angeles got hit by El Nino pretty hard with thick clouds for about a week but didn't have any issues with my navigation. I use TomTom go, Google map, waze, and MS Here depends on my mood but all were accurate. I haven't done anything to my phone except turning off WiFi assistance for GPS, you think that has anything to do with it? I think it was called WiFi scanning under advanced WiFi setting.

I find the LG G4 gps to be one of the best among the phones I have used. I have had Note3, Note4 before... those had horrendous gps performance issue.

Nexus 6 Signal Loss

Yes, this time old issue still exists for me, and it makes it where I cannot trust the phone. I've wanted to use my Nexus 6 as a daily carry, but have to use my LG G3 instead.
The N6 completely drops cellular signal after the screen turns off and goes into deep sleep. After waking the phone, it requires a reboot 90% of the time to get it to reconnect to cellular service. Rare occasions I can leave it for a few minutes, toggle airplane, and get it to reconnect, but by then a reboot is faster. Obviously, a phone that drops cell service when the screen is off is no good.
The fun thing is not ONLY is it dropping cell service, it maxes out the cell radio searching. If I don't notice it dropped service, the phone gets hot and the battery dies very quickly, this also happens in AIRPLANE MODE. Yes, even when airplane mode is on, I turn the screen off, cell service "dies" and the radio kicks on and searches for signal, gets hot, kills battery, all while in airplane mode. The battery information page shows blank for the signal meter while in airplane mode screen on, but turns red and shows indication the radio comes on when the screen is off.
The only "solution" I have is to constantly play music, or have it plugged in. Currently I have an 8 hour mp3 of pure silence playing on repeat. Naturally this keeps the phone locked at 300Mhz while the screen is off and never sleeps, but the cellular radio works as normal, stays cool, and battery drain is minimal, never disconnects. The problem is: doing anything that causes said silence to pause and not noticing/remembering. Watching a video, casting something, rebooting, etc. Also the phone never sleeping is generally not good, but I can't trust the media player not to sometimes stutter and then the signal drops out. You see my trust issues. While the phone is plugged in, which also prevents deep sleep, the phone is fine as well.
Oddly enough SOMETIMES the phone does as it should. I might check the phone and notice music is *not* playing, but the signal is fine, and the device has been in deep sleep with no problems. I've yet to isolate what causes it to stabilize, but after a reboot, it's back to its old ways.
Things I've tried:
Flashed ALL the official images. (Problem exists across them all.)
Tried a few custom roms
apps that hold a wakelock. (trying to keep it from sleeping, which worked, but signal still disappeared)
Removing, downgrading, upgrading, etc Google Connectivity Services.
Different basebands
Different carriers.
Other things I can't think of now.
Current Setup:
Pure Nexus (latest)
System mode root + Xposed system mode
Bootloader: moto-apq8084-71-21
Baseband: D4.01-9625-05.39+FSG-9625-02.113
Attached a logcat of it dropping signal after screen off, and luckily caught it regaining signal as well in the same logcat.
EDIT: Alright, can I get a moderator to move this threat to Q&A. I posted in Q&A and it appeared in General... Guess that's what I get for having multiple tabs open.

sim issue
yes, this seems to be issue with N6.. (issue is somewhat related to SIM card). Can you try without SIM card inserted?

Just sell the phone. Dont waste nerves trying to devug it.
I had similar issues, but switching to 2G helped.
To be honest, these smartphone issues have been things i have experienced with all brands.
From random reboots with samsung, cellular issues with LG to phantom clicks with sony. Not acceptable given the price.
So far, every smartphone has caused issues.

I'm not the type of person to sell something with a known issue, that's as bad as selling a car that you know the transmission is about to go out. Since it's not my main phone, I don't let it really get my nerves, instead I use it as a brain teaser. Finding new and interesting ways to get it to keep working, but at the same time I would like to find an actual fix. In case I ever want to... y'know... sell it. I'm not going to sell a defective product. I have the experience and knowledge to actually use it, and on Fi it's a good backup. The wifi doesn't cut out so it still works if I'm around wifi.
Also, replying with "Meh just sell it" is a very unprofessional and indecent response on a large forum dedicated to helping people and making their lives with their phones easier, and learning new things along the way.

I never said that you shouldnt disclose that the phone is defective.
I assume that goes without saying.
Secondly, my experience has been that such issues are unfixable.
When i had an LG phone with issues, the solution was to sell it as scrap/defective device.
From the looks of it, your issues are unique. I also have issues with connectivity and the solution was to switch to 2G.
However, it only happens with one network operator.
Also, this is a forum, you asked for advice, i gave it to you. You dont have to like it.

Oddly enough without any system changes or anything and with how long the problem has stood... It seems to be acting correctly now. Doing some tests with reboots, etc and it seems to be going to sleep fine and not losing signal. Will continue to monitor this oddness and if I figure anything out, I'll update this thread for any of those who might still have this issue.
