[Q/NEED HELP] GPS inaccuracy

Hello everyone. As you can see I have a GPS inaccuracy problem. My phone fixes to 7-8 satellites really fast (approx. 10 sec.), but when I use Run Keeper/similar sports tracker or Google Maps my trail is like zig-zag, app shows that I'm moving at crazy speed and so on. I tried AGPS Patch 3.1 by crypted, GPS fix by xenova, flashing some Radios (31_M and 18_M), ROMs and kernels (currently ARHD and Sultan kernel, tried ViperS, CM10.1), but nothing helps... I add some pictures which show my trail when I went across street (Vilniaus g.). Please help. Thanks

Nobody knows what problem this is?

If the problem remains also after wiping all, I think it could be an hardware issue.
Have you always had this problem?
When you use GPS while driving your car, the path has the same issue?

Totally wiped and installed CM10.1, but the problem remains. I bought it used. I don't know how much time it was used, but the digitizer had stock glue and the VOID is not damaged. No rust. So I think the previous user didn't have problems with phone. Never used navigation in car because I live in small country, which doesn't require any navigation to drive across Can RUU affect this? I really need normal lock...

If you try using only google maps? Test it making sure that it is the only app using GPS (kill background open apps).

i have the exact same problem! I've had the phone for a while, so maybe it's something that is worn. I'm thinking about the connections between the antennas and the phone for example. I hope we can find a solution! It's independent of which rom I use and which apps I use.

Have you seen this tip? "New Sensation Install - Gps Problems (Fixed)" @ cyanogenmod forum.
I can't find the option in cm10.1. So maybe they removed it or changed it to something else.
I'm thinking about flashing cm9 just to try it..
(I'm to new to post links)

Google Maps behaves exactly the same. Arrow, which shows my position, jumping all arround my street pretty much the same as in RunKeeper.

I don't think that this is something software specific. I think that the problem is hiding somewhere deeper but not in software, because all roms and different radios behave the same way. I think this is something hardware related.

Mmm, then I think it's an hardware problem... try to contact HTC support!

Hello again every one. I don't want to create a new thread so I'm writting here. Maybe someone knows what problem this is? HTC support, as always, suggesting me to do things like resetting phone, pulling out the battery, fully charge and so on... I thinking about selling this wonderful phone because of such a big problem... I can't use GPS everywhere...

Gps inaccuracy problem is also facing to me too.

I solved it by flashing the latest firmware and use clocksync before each time i run. Works reasonable, but the clock drifts quite fast. It wasnt enough to only use clocksync or only flash firmware.

It's back.. I've ordered an Omate Truesmart to use for running instead..
My thoughts are that it could be the gps antenna connections to the back. I have no other ideas..

[APP][4.0+] CellCB - Talk with people nearby just like a CB radio

I recently put up a new app on Google Play called CellCB and thought I would post here to try and get some feedback on it. CellCB is an app that is meant to behave just like a CB radio in that it will allow you to talk with people within range of your phone. Unlike a traditional CB radio it does not operate on the 27 MHz band, so sorry to the folks who were hoping to use it as an alternative to the bulky unit they may have installed in their car or truck. What it actually does is use the GPS system on your phone to figure out what other CellCB users are in range on your phone and list/broadcast to them over the Internet. Right now it is set to a range of 4 miles but I may make this more/less in the future depending on usage.
CellCB is meant to be simple to use and closely simulate the behavior of a CB radio as much as possible:
Launch the app - Like turning a CB radio on it will immediately start listening for people broadcasting nearby
Hold the "Transmit" button - Like holding down the button on a handset it will broadcast your voice to people nearby
I hope to implement other features such as multiple channel selection, probably 40 like CB radios have, as well as some extras like making recordings and such. For the time being I just have the basic functionality with a single channel to see what people think and understand how well the core of it works. My goal is to keep things as simple as possible and therefore there is no type of registration needed before using it and no special configuration is needed like other apps that perform walkie talkie functionality over wifi or bluetooth.
https://play.google.com/store/apps/details?id=com.binaryroad.cellcb
Feel free to let me know if you have any questions/comments. Since this is a pretty new app you will probably need to find someone else to use it with, otherwise the chances of hearing someone broadcasting nearby your position at random are quite low.

If you go into Google Maps does it give you a fix on your location? Were there any messages about permission for location services?

Looks like the server crashed. I restarted it so give it another try. Looks like I still have some bugs to work out. I appreciate the help in giving it a try.

If Google Maps doesn't give your position either then it sounds like a problem with your phone in general and not CellCB. If your aren't able to get your location on Google Maps after a while you might want to contact the phone manufacturer about getting GPS working on your phone.

Thanks for everyone who has been using this so far. I found a bug that would happen with people who were on flaky connections and have fixed it now. Hopefully that was it and things should run smoothly now.

I have made a couple more fixes to deal with some issues for how location updates are done for certain phones. If anyone encounters any trouble with the current system, please let me know.

Nice idea.

can confirm, just got it as well. Installing as I type this

Good to have FM radio back with this update, Installed NextRadio, plugged a 3.5mm cord in, checked output to speaker, and was able to tune into all my local stations.

FM radio activated is huge. Hopefully any other little bugs are ironed out as well.

includes may security updates
also has latest may 1st security updates. I am really impressed by the support for updates and speed. definitely better than my note 4.

Any app that I can use that doesn't have ads for FM radio?
Tried spirit1 and spirit2. Spirit2 just says I need root, and we know that's not happening right now. Spirit1 says I need to plug in headphones, when they are plugged in. Reading the thread for the app here on XDA I don't know if it will support our device though, but figured I'd try it out.
NextRadio works but has ads and I don't see a way to disable them with an upgrade. I tested NextRaido with wifi,data,Bluetooth,GPS,nfc all disabled/off and it worked. Just want something without ads flashing at me, I don't mind a price.
Is there something I disabled with package disabler pro that Samsung includes for it?

tunein or iheartradio ???
FM radio is kind of stupid anyway, I could care less for FM enabled since apps such as tune in and iheart will give me access to almost every station in the world plus the quality of NextRadio stations is only as good as the FM signal.

It's very good for those who like to listen to local sporting events such as MLB and NFL games. The local games are broadcasted on certain FM channels but are not broadcasted to the web version of those online channels. Radio stations only have local rights to broadcast local sporting events and do not have the rights to broadcast them over the world through the web. If you try to listen to these stations while they are broadcasting a sporting event in real time then all you will hear is either music or a repeated talk show they aired earlier that day.

FYI, this update patched a Qualcomm "elevated local privilege" bug that could be exploited for root in the near future - I'd advise not taking this update if you didn't already and are looking for root - this might be the break we're looking for.

But Tune In and iHeart radio use a data connection. FM radio is good in those situations where a data/wifi connection isn't available.

Samsung s8/s8+ wi-fi nougat fix !!! (aka s7)

just like in s7 nougat
nougat wi-fi fix (losing connection & reconnect) 5Ghz band
Settings > Location > Improve Accuracy > Bluetooth Scanning : Turn it off
also disable "smart network switch" from
connection-wifi-advance-smart network switch Turn it off

That's good for battery life?

I did not see so much difference but it's a thing that you not use.....

what does it fix? which wifi problems?

Actually I do use Smart Network switch, I switches between LTE and Wi-Fi. I also keep LTE alive in the background for faster switching.
If that is turned OFF - I get periods of "no data" usually when I am trying to navigate and the device had locked on some "Xfinity wifi " as that is a very common open wifi.
I am and most of us are "not paying LTE so we don't use it" - This feature allows for better Network switch and less periods of No-Data, IMHO

My device is a non branded edge 7, which also uses both of them simultaneously - that's a thing of beauty

That must be a regional issue. My S7e never lost a wireless connection or had problems moving between cellular and Wi-Fi. Regardless, both the radio h/w and s/w are going to be new on the S8 so things that affected previous phones aren't likely to affect it. We'll probably getting a totally different set of new issues and quirks.

As in you're in the EU and I'm the U.S. and haven't experienced what you're reporting. I also don't remember seeing chronic worldwide wireless issues on the S7e forum. So it doesn't seem like whatever the problem you're referencing is affected all S7e owners equally. And it certainly won't affect S8 owners because the radio h/w and accompanying s/w is new.

how wipe cache will going to work on s8 ??

Instead of home button you must hold Bixby button

Seems like no matter what I turn off, wifi still toggles automatically, I've wiped cache, booted into safe mode, factory reset, took away permissions to system settings.
Is there a way to trace what is commanding wifi to toggle?
Maybe if I can trace it and will be able to disable it
I see that no apps have requested this through the "wifi control history"

I knew I couldn't be the only one experiencing this, so I'm glad there is at least discussion about it.
I made a related thread in the Q&A this morning before I found this thread.
I'm on the T-Mobile S8, and I do connect to a 5Ghz band. Thankfully I don't use smart network switch nor do I want my device scanning for bluetooth when I have bluetooth disabled (they say it's for "location accuracy", but it's actually for ad services).
I only disabled bluetooth scanning when bluetooth is off a few minutes before finding this thread, so I'll report back if wifi continues to drop in the coming days.

Same for me. Did you install some software update?

Well I've been messing around with this issue for hours and hours. The only solution is to set my routers to 2.4ghz because 5ghz makes this phone go crazy.
Just my 5 cents -> do this or stop wasting time until either Sammy releases a fix (doubtful) or root + custom ROMs start appearing (more likely) so a specific Dev fixes the problem.
This much money and I haveto change MY other equip to have it working.
Bah!

I did install an update that came out a day after I received my s8, but this was happening before that as well. And if happened right out of the box, during the initial set up.

For those of you that are losing Wi-Fi connection and reconnecting, go into your router configuration and change the channel until you find the channel that is most reliable in your area. That's usually the main cause most of the time for disconnect issues. Change your 5Ghz channel and you most likely will find one that works fine. If the router is in "auto channel select" mode, take it out of auto and set a channel manually until you find the channel that works for your area.

Anyone else has the same slow starts?
EDIT: fixed it! Disabling ADB debugging solves the delay (found out using logcat)

Works fine for me on 2018 Acura. Only issue, as referenced above, is if the notch is hidden, it cuts off the screen on the car's display.

Works fine in my [emoji176]Kia Rio 2018[emoji176]

Had to disable the notch hide... grrrr, works fine, not as snappy as my pixel 2 xl in android auto though, connected to 2018 Jeep

works fine on Chevy Volt 2017.

Yep is fine for me. Was tricky to initially pair but after I changed notch setting it worked. 2017 Mercedes.

Cool! I've never actually used Android Auto. (Mine's a much older system, so too prehistoric to have smart related stuff, but after seeing this, I'm now seriously thinking of upgrading). Does it give you access to all of the stuff on your android phone, or is it just basic stuff like syncing up music, etc?

Its a long-ish answer so just download the Android Auto app on your phone and see it in action. What you see on the phone running the app is what you see in the car (aside from integration with steering wheel buttons etc).

Work fine with Skoda Octavia 2018

It mostly works for me but I have to change the connection mode from USB charging to MPT every time I want to connect to my car. Otherwise, it won't detect the phone.
This is with a Honda Accord 2016. The car connection has the same issue with the OnePlus 3T but not with a Motorola phone that I tested.

Oh Ok, this sort of answers my question anyway. (so basically it's more of an app than a built-in full blown Android OS on a car stereo). In other words, limited features rather than a full OS.. Not alot of point for me then if that's all it does. (Mainly I would have used it for music and gps in the car, but I can already do that from my phone easily enough). But if it had been the whole Android OS that does literally everything my phone does, then that would have been totally worth it!
Thanks for the heads up though! What feature do you use yours for mostly?
