Accelerometer problem - Verizon Galaxy Note 4 Q&A, Help & Troubleshooting

The accelerometer in my Note 4 is constantly jumping between 0g and 0.1g. I've tested this with several GPS apps and they report the same problem.
Turn-by-turn navigation is useless because of this issue. I'll stop at an intersection and the navigation program will show I'm still driving straight ahead. After 10 seconds or so it'll recalculate my actual position and move me back to where I actually am. If I make a right turn, it'll show me driving straight ahead for 10 seconds before fixing itself. I've tried a factory reset and calibrating the compass/pitch/roll in the GPS Status app.
I wanted to see if anyone else has/has heard of this problem with a Note 4. My current plan is to ship the phone to a Samsung service center on Monday.

GPS/Navigation problem... app, mobile or something else?

Hi, I'm really not sure what to make of this problem so maybe you can help me out pinpointing the problem so I can take care of it. I've observed several things and don't know how to connect the dots, or if there's any connection, so let me list what I've been seeing:
1 - I've got TomTom to use on my car.
2 - Worked wonderfully well on the first week or so. Fast to lock onto satellites (10 to 20 seconds), accurate and stable without loosing the lock.
3 - I've noticed from day one that it tends to to locate me a few meters back than what I'm actually am, so if I come about two streets very near one another, the turn on the correct one is a bit hard to to tell without looking at the map.
4 - A week ago, the phone started to take longer to lock my position and won't keep it, it often loses connection with the satellites.
5 - Also, the problem is a lot worse if I stop. It might be accurate while I'm driving over 50mph but, if I stop, the direction I'm facing is lost and then my location. It will place me within 50m to 100m of where I am, which could mean on another street. It has become useless for the slow paced city driving, with red lights and slow traffic.
6 - I haven't changed ROMs or anything major but I have downloaded a few apps, might have taken a few others out, the usual stuff... I'm using Android Revolution HD 31.2.
7 - I've noticed that a lot of times, in regular mobile use, the GPS icon shows up trying to locate my position, even with GPS off. Might be that I have accepted Google's location request or is embedded on some app. Don't know if this has any relation to the workings of navigation or with the timeframe the problem occurred.
8 - A final though... I've always had this problem with standalone GPS devices... They work fine for a few weeks/couple of months and then they seem to deteriorate, having a hard time to locate my position, maintaining a good connection, etc. I have no idea on why this is or if there's some sort of cache I should be cleaning.
Oh, and this happens regardless of the weather... overcasted, rainy days or clear skies, it's all the same.
So any thoughts on how to pinpoint the source of the problem so I can fix it?
Cheers!

[Q] GPS Problems

If I try to navigate from the Zenwatch, the phone brings up google navigate even if the phone is sleeping. I would think that might be an issue in a pocket, but that's not the biggest issue.
The destination seems to get set correctly but neither the phone or the watch continues to navigate. They both seem to lock up.
Subsequently any other Nav app (I hope Waze gets Wear support soon) is unable to navigate as they are unable to get GPS lock. Looking at other GPS helper apps shows zero sats in range. Stopping/Restarting location services doesn't solve the problem. Only resetting the phone does.
Maybe it's just me. Sprint HTC One Max, stock. Anybody else?
I noticed this the other day when I was testing out navigation for fun. Once I took my phone out of my pocket, it seemed like it was able to get a lock again and things went more smoothly. I know gps can be a bit sensitive sometimes and maybe having it right next to your leg like that blocks the signal?
When the problem (GPS lockup) manifests there is nothing that will get it going other than a phone reset. I normally have my phone in a holder high on my dash where gets good reception, but when it gets in that state, not even one satellite shows a hint of a signal. Today I even made sure to stand outside holding my phone up in clear sky just to be sure.
Even if I don't access nav Google maps or Micro Maps from the watch it still locks up at some unknown point. I normally keep GPS on all of the time and have a number of apps that store locations from time-to-time. When I get in my car, Waze automatically starts but I can't get any sat signals until I reset my phone.
I'm experimenting with a theory that another member brought up in a different thread that there may be a connection with using a watch face that also includes weather and the number of GPS requests it makes. I've changed to the basic face that is in all of the marketing photos and continuing to test. I guess my next step will be to leave the watch at home :crying: to make sure that something wonky hasn't happened with the phone itself.
Are there any other frequent GPS users out there that can confirm or haven't experienced the problem? It doesn't seem to matter if you use the nav functionality on the watch.
The updates this morning seem to have fixed the problem.

[Q] Galaxy Note 4 GPS Issue (Stock)

I just swapped out my SGS3 for a Galaxy Note 4, carried by Verizon, and I'm having GPS lock issues. This phone isn't even a week old.
My phone is as stock as it comes under Verizon. I used Google Maps to drive somewhere across town and it'd place me blocks or miles in the wrong direction. It couldn't track me, either. My phone also notifies me intermittently that it's "Found my location." Lies. Though, at least it knows I'm in California, so that's a start.
I downloaded the GPS Status app to figure out what the problem was. Apparently, satellites cannot fix on my location. The app lists that 0/20 satellites have a fix on me; that number is largely unchanging. If I pull up the app while I drive, the satellites can fix on my location, but as soon as I switch to another app, like Google Maps, it loses my location lock and thinks I'm anywhere within a five mile radius. If I pull the GPS Status app up again (at times, while driving--not always), the satellites can find a lock on me. If I switch out to any other app, the satellites drop me and the process repeats. The GPS lock lasts 10-20 seconds after switching out of the GPS Status app before going to ****.
I've tried taking out and re-inserting the SIM card. No luck. I've tried factory resetting my phone. Some luck, but 16 hours later the same issues began to arise. I've tried doing both at the same time. No luck.
There is another incredibly peculiar thing that happens simultaneously: the stock Accuweather widget that comes with the Note 4 (listed as just Weather under widgets) goes all wonky. That's when I know my phone has gone from being able to acquire, and maintain, a GPS lock, to dementia-ville. And by wonky I mean that it goes from showing the time above the date above the weather above the city to showing the time on the left and the weather and my city on the right. Replacing the widget on my home screen works for a few seconds, or until I refresh the weather, and then it topples over and reports its information from left to right instead of top to bottom.

I'll be around to troubleshoot. Any help is appreciated.
I've also been having this problem, without data or wifi it doesn't even try to lock onto my gps location. I also see "location found" when my gps is turned OFF. I've also tried factory reseting and I've even contacted verizon tech support, to no avail they said I had to return the device but my gps worked fine before the update to lollipop so it could be a lollipop bug.
The GPS only works with wifi or data turned on. The GPS on my note 4s work very well.

I see this post is over a year old, but here's a fix in case anyone is still interested: see last post (by the_fixit_guy) in this thread .
This solution fixed the gps on my note 4 and it is working like new now. My battery life has also improved tremedously (probably because the phone isn't constantly trying to get a satellite fix).
I had the location spoof or whatever from dev settings and disabling that fixed my problems.
I had GPS issues on my Note, and that worked for me! Thanks!

Anyone having issues with Waze and GPS?

Having issues with waze app and GPS. I've always had GPS issues with all of the Note series, so this doesn't surprise me. But this time around it seems like waze is the only one acting oddly. Specifically when I'm on a guided route waze intermittently sees me in a different area, most commonly when I'm on the highway it will see me on a side street running parallel to the highway. So then it thinks I'm off course and routes me back onto the highway or another direction, but I'm still on the highway. Sometimes I think it even sees me traveling a different direction, many times I'll be on the highway and it will want me to do 2 u-turns, changing directions twice but ending up going the same way as before. I also see the arrow icon representing my car on the map will constantly turn as if waze can't tell which direction I'm traveling.
My first thought is faulty GPS. I've ran Google Maps and it seems pretty solid, with none of those errors, but I'll have to test some more. Just wanted to see if anyone else got this? I may switch back to an older APK and try that as well.
No problems here. I noticed the 7's gps is way faster than my note 4 too. It finds my location on a second. My note 4 would take 5 to 10 seconds to lock in
I am having the same issue with Waze on my Note 7. It thinks i have turned onto a side road so it trys to redirect me to the the road im acually on. Its seems to think im about 30 to 50 feet to the right on the screen no matter what direction on the compass i am going.
Sent from my SM-N930P using Tapatalk
I've been having an issue when I'm stopped at the light, and the screen will start to spin around. It's like Waze forgot which way I was going so turns me around & recalculates the route...repeat.
Improvement over my Note 3 which regularly couldn't find a GPS signal or lost it in the middle of driving somewhere.
Were issue
I have been having issues also bit but only with the voice guidance. I get hazard alerts but that's it. Any thoughts on this?
waze always seemed to place me about 50 feet to the right of the road. It spent a lot of time recalculating on/off ramps when it didn't think I was driving through corn fields. I figured it was just a calibration issue with my device and didn't do anything about it before swapping it for a non-exploding phone.
I had no problem with my recalled Note 7. The replacement is messing up with waze. All the symptoms listed above are happening. Ugh
Hmm..that's not good..I still need to get mine replaced...
No GPS issues with Waze on my note 7. I use it daily and mine is a replacement. The only issue im having with Waze is the voice commands. The three finger option and waving just don't do anything! Anyone have an issue with that? I want my one eyed purple monster back!
IDK, I haven't checked on my Note 7 yet, I find this a bit funny though, Most GPS's should be accurate to within something like 5 feet, They are really accurate to within fractions of an inch but the Government and Military makes sure that the firmware on the GPS's for use by the general public are locked out of that level of accuracy. It really is a joke these days.
Do a search and in the search box enter in 2##2 to enable debugging and then enter in ##@rawgps and it will show you what your phone is reporting as the actual raw GPS via a yellow arrow. Send in a debug log on the very bottom of the settings every day. Could be possible that Waze can make adjustments to the note 7. I personally haven't noticed any issues with either phone yet, I do also keep my phone in a case and in a windshield car holder with a good view of the sky. When I ran the app for the first time though I did have to toggle location off and on to get Waze to get a GPS lock.
I returned my replacement unit and got another Note 7. No change. Waze is still showing me taking exits and being on the side road before correcting. Very annoying and the constant recalculate and accompanying chime make it onerous to use. Google maps seem to be fine. I submitted a ticket to waze as well as sending log files. I hope a fix comes soon. I need my alerts when commuting.
I fixed my Wave problems. Apparently when you do the smart switch transfer, it transfers some settings or calibrations maybe. I went into phone settings, application, waze, long press storage, clear cache, clear data. Then Uninstaller and re-download and install waze. Mine has been rock solid since doing this. Hope it works for you too.

Problems lately with GPS

Just recently over the last couple months, I have been having a problem with getting a good gps signal in programs such as Waze and Google maps. I have done all kinds of searches and many mention to go into settings and in location settings, turn on High Accuracy. That option is bo longer available and not sure if it was eliminated in Pie. I have been doing all the latest updates and believe I am current. The only thing I have been able to find is to go into settings, then Biometrics, and there I found location. The only choices under Improve Accuracy is to turn on Wifi scanning and Bluetooth scanning which I have done. There no longer is a choice of High Accuracy and the ability to turn GPS on or off like I had in previous phones and previous versions of Android. I have even tried turning on High Performance under Battery Power settings and turned off any choices to optimize battery or disable apps. I ended up downloading 2 different GPS apps from Store, GPS Status and GPS Fix/Optimizer. I will normally use Waze or Google maps through Android Auto. I can tell when there is a problem when the position indicator keeps bouncing all over the place in Waze and cant find exactly where I am. When that happens, I will check on GPS Status and it always shows that it is having a problem acquiring the satellite signals. I will then open up GPS Fix/Optimizer and on the home screen, there is a button that will say Service Off. I press it and it will then read Service On. Switching back to GPS Status will now show that it is starting to acquire multiple satellite signals. When I switch back to Waze, now it is able to show my exact location and begins to work properly.
This is driving me nuts. I never had this problem on any other of multiple different phones or Android versions. I can get GPS working but have to jump through all these hoops each time and it sucks. So what other steps can I do to be able to fire up Waze and have it find me right away?
It's not just an Android Auto thing, it happens with GPS in general. There have been many posts about it over on Reddit in the Note 8 Forum dating back to March. The best fix is to just toggle location whenever you notice that GPS isn't working.
The scary thing is not only has Samsung not even acknowledged there is an issue, newer phones are also starting to have the problem. Just saw people complaining about the same thing in a S20 forum. Just like our issues, they started after an update.

Did you ever find a fix for this problem ? I am dealing with this too and have been for a while. GPS when using as a phone is no issues at all but, once you connect Android Auto, it's a mess. Very hit or miss and even if I hit where it works, it will drift off and require me to unplug/re-plugin my Note 8..
I posted to a few other places on this issue, nothing has solidly fixed this. Otherwise my note 8 works fine, so I no reason right now to upgrade, till the phone I want drops a little in price.

Anyone else figure this problem out ?
I still havent found a fix. Here is another thread I started on the main Galaxy Note 8 that produced a lot more discussion but sadly, no fix yet.
https://forum.xda-developers.com/galaxy-note-8/help/recent-gps-problems-t4058849
For me at least, it seems like it may be an issue between Android Auto and my Chevrolet. Still not entirely convinced but folks over at Android Auto claim that there is a communication problem with Android Auto trying to communicate with the internal gps on my truck. Supposedly even though I dont have traditional on board navigation, there is still gps communications going on. I believe that with Chevy, it is the onstar system. Android Auto is programmed to utilize vehicle gps because it is supposed to be more accurate. Unfortunately, if that is the case, and there is constant communication error between the Note 8 and vehicle, the result is that the apps in AA like Waze and Google maps continually have location errors. I inquired why AA couldnt just allow users to utilize the phone GPS as an option and was again told that a vehicle gps would be way more accurate so that option isnt available. When unplugging usb from vehicle, it defaults to the phone GPS and begins working again almost immediately. So is the problem with AA programming or communication problems with my Chevy truck? Who knows. Sometimes they communicate just fine from the get go but other times, not so much. I just wish the problem could be fixed. I would be leaning towards AA programming as this does not just happen with Chevy vehicles but AA just passes the buck.

Yep, saw that thread as well and the one on Android Auto's site, I even replied to it. Wishing there was a solid fix here but, no... I have a Lexus LS that I added on a 3rd party Android auto device on. I had this same issue when I had a 2019 Ford with Android Auto as a rental. I figured 6 months later (I just put AA in my car about 2 weeks ago) it would be resolved by now.
Not 100% sure it is the GPS car thing you were told, as other phones plug into Android auto and have a seamless experience if this was the case, all phones would have this issue. We are using the same software. So why is the Note 8 different ? Well, I hear this effects other Samsung phones but, none as bad as the Note 8. Newer Android 10 even Samsung phones do not report this issue, as far as I have heard.
Oh, well the quest goes on... If you find something, please drop me a line....and thanks !
"Me too" - Driving me crazy. Toggling Location services off and on sometimes helps, but not always. I'll be moving, and the map doesn't reflect any movement.

Toggling when driving is not a good idea, Normally unplugging and plugging back in works just as well. Funny for the last week, it was working fine (get lost when in a lot of trees and sometimes not recover but, on the highway it was perfect), till this morning and it was a mess.
There was an update for the Note 8 on Verizon a week ago, I need to double check all the power saving features and make sure they are fully disabled...
I had also started a thread on the Google Android Auto community back in May where the developers monitor posts. Just recently (about a week ago) it seems they are acknowledging that there may be a problem and posted they were going to send out emails to several that were affected by this. They gave directions on how to forward a bug report to them when the problem showed up. I was one that received the bug report email. I have since submitted 2 bug reports to them but have not received any kind of reply. Hopefully I hear back sometime soon and they are able to identify exactly what the problem is. If I do, I will post their response...
