Location + Wifi mess - Samsung Galaxy Note 9 Questions & Answers

Why does Location turn on whenever I connect to a Wifi network? I never had this kind of behaviour before. How to stop this? I read online that disabling Locate my phone would do the trick, but it doesn't.
Also, since a few weeks, I always get the Location consent dialog, and even if I agree, it always asks me. I want to always agree and stop being asked every single time. Even Xposed modules don't do anything on my rooted S7E. Do you guys have any hint?

Yeah you can't turn them off now.
I figured the only way the data collection won't hurt me is if i don't have any accounts synced to my phone.
They tied down the Geo location for most radio connections the phone has.
Irritating. You can toggle by using the phone gps only but my experience, my map apps tend to not work unless I use the high setting.
Most phones has AGPS units where it's always assisted by other connections.
And individual gps units are exactly that: gps (garmins... Etc)
Good luck

[Q] could wifi be the problem with samsung captivate's gps issues

anyone else notice that when using the Samsung captivate & navigation that is recommends turning on WiFi. it doesn't make sense, but i notice it makes a huge difference in speeding up satellite connection time with WiFi on.
could this be the issue with the GPS??
please confirm this.

This is not a fix. Turning WFi on will help give your phone another source to determine your location. The key thing here is that WiFi cannot determine your location as accurately as GPS can. If you look again, you'll probably see that your phone will "lock" onto your position much faster, but it's probably not going to be accurate enough to be usable.

you must have read the title before i edited it.
im not using the WiFi as a location source since i don't have any WiFi internet on the road.
but i notice that the GPS locks on quicker than without the Wifi on.
my nexus one never suggest to turn on WiFi when using navigation
Its not necessarily wifi based location but it can use wifi to download gps data. For a date lock. Its just a suggestion, I don't see why out would make a difference with out a wifi signal.
I prefer to not have network location or sensor aiding enabled. Sensor aiding really doesn't work. Made my my tracks results erratic. Network location gets me within 2 miles, not exactly good for navigation, having it on only allow something to fall back on of you lose gps signal but the whole process of the phone switching from one source to the other and back again takes to long. Keeping network location off forces it to only try to get a gps lock and in my opinion works better.
As far as wifi, if you believe it works better that way then do what every you think helps. It really should only download the data and once it has it it is done with wifi un till it needs new data which usually won't be for several hours.

Tasker Location/Wifi Near Actions not working too well...Pls Help...

Hey,
Love Tasker, like love it...but, some of the things I'd like to do, the major ones, just aren't working out....it's probably me not setting them correctly, don't know...
So I need something simple really...
- Come home, turn wifi on, connect, turn mobile data off (would prefer to turn to GSM from WCDMA Auto but not sure if you can without root...)
- Leave home, wifi off, mobile data on...simple in theory...
Have tried locale based (gps) profiles, wifi near, cell locale...to not much avail...if just swaps back and fro, doesn't know whats going on. So I'm just seeing if anyone has been able to do this easily and efficiently...
Cheers.
I recently raised this myself. Basically the issue is that Google no longer allow apps to turn WiFi on or off. As such, that kind of profile won't work.

GPS still terrible on 2.3.4 sprint tab

First of all, yes I searched the forum, and google, and tho I might have missed something, I think I've tried most of the reccommendations out there (short of a custom rom because those are in short demand for the sprint tab.)
I did a wipe / odin to 24, updated to 28, then 2.3.4. Gps still sucked, so I flashed rooted 2.3.4 and tried 3 or 4 gps "fix" apps for this thing, none of which have made any difference. I can get gps but it takes FOREVER, usually around 5 minutes. Often it will find 6 or more satellites too, but just sit there and not lock on or whatever to any, then randomly it works. I've tried every combo of toggling gps, soft reset, and hard reset.
In texas I had the same problem on froyo, now I'm in Costa Rica... I'm assuming since gps stands for GLOBAL positioning sys that where I am shouldn't affect it. But its just SO darn slow ilby the time it starts working its useless.
and I test it outside on sunny days with open sky, so I know that's not the culprit. Nor ia it in a case when I try
Any thoughts or ideas at all would be MUCH appriciated as I really need to start using my tab for mapping.
Thanks!!!

I think you're doing it wrong son. Try these settings. In wireless and network, mobile networks, uncheck 3g data. In location and security, check both use wireless networks and use GPS satellites. I assume you are using wireless tether from phone to give tab internet. Turn wifi on obviously. You do have the modded wpa_supplicant file for ad hoc for the tab right? I tried timing myself after doing all those settings I said and how long with GPS tools app and Google maps to get a lock and it was immediate. This is coming from never have using the GPS since the complete back to stock with ea24 all the way up to rooted gb.
People are saying to put the tab into airplane mode. If you want to use the GPS or things like weather bug or radar now, you at least need to have location from network enabled for it to assist in finding your location. You're not pulling data from the tower, the tower is helping the apply to locate where you're at, along with the GPS. GPS alone and wifi didn't work for me. When I enabled the settings I told you about, the GPS apps immediately came to life and worked great.

I'm in costa rica with a cdma sprint tab, so 3g is always disabled, and because there is no service I disabled network location because I figured it couldn't get that data with no signal, and my location kept going to some random location around the world. And when I need gps I'm out far away from wifi hotspots too, so not worried about that setting I don't think.
Wifi hotspots only, no tethering, and I don't have the wpa supplicant file, but again no tethering so I'm assuming that is not nessicary.
And in Airplane mode it never gets a lock. At least on froyo it never would. I would turn airplane on then activate gps and it never ever found a satellite. I researched it and I thought in airplane the gps couldn't function until airplane mode was disabled again, even if gps toggled...
I appriciate your input, but I don't think its going to work given my circumstances.
Thanks!

[Major Bug] Wifi Always Scan breaks Location Services

Hello everyone.
I just wanted to get your attention on a major Android OS (Kitkat) bug in the interaction between Wifi -> Advanced -> Wifi Always Scan and the Location Service. Clearly the bug doesn't happen every time, but sometimes it does, and obviously I'm talking about stock rom / kernel / no root / locked bootloader.
Althought I can't prove it, this might also be the cause of the current GPS / Navigation issues, currently being reported here.
What makes me link this to that issue? Because when Wifi Always Scan bugs out, it prevents my phone to acquire a location even from the 3g network.
That would explain why in that thread many people report that they could navigate with Device Only, which doesn't use 3g or wifi for location, but they had major issues with High Accuracy, which uses all three sources.
Please take a minute to star the issue so that Google will hopefully fix it faster.

Thank you,

Just turn it off, all it does is waste battery anyway

Thanks for your useful contribution.
It doesn't waste battery, it saves it. It enables to use the wifi location using a lower power state of the wifi chip compared to actually turned on wifi (which is also more accurate by miles than 3g location, works indoors in clubs where there is no 3g or gps signal, and not as battery expensive as gps location).
Also, people use that option for many things, I for one use it in MANY Tasker tasks flawlessly, whether the alternative (wifi periodic toggle and polling) would rape my battery.
Wifi automatically Turned off. Built in feature?
I kept my wifi on, and the had not used it basically just left the device in the room and had run off.
When I retured, the wifi was on in the power control widget but the wifi signal indicator icon in the notifications bar was absent.
is this normal/intended?
My wifi / internet connection is weak but continuous and my device is about ten to twelve feet away from the modem / router.
Can anybody help?
Although I have not a Nexus 5, my problem seems to be the same. I'll tell you if perhaps serve as any indication.
In my HTC EVO 3D, I've been running since the summer with CM10.2 (Android v4.3.1) with location mode set to "Network & WiFi" and "WiFi Always Scan ON". During this time the location was very accurate, location history left a fairly detailed trace. In Google Maps, was located immediately, as in Google+. If activated the GPS, even better. Summarizing, 0 issues with the location.
On January 1, I decided to upgrade to CM11 (Android v4.4.2), I set my location mode to "Battery Saving" & "Wifi Scan Always ON". During the first 10 days everything was perfect, the location history trail was so detailed as CM10.2 and battery consumption a little better. Google Maps and Google+ also positioned themselves almost immediately. Suddenly, on January 11 the location seems to stop of using WiFi networks and began guided only by the Network Cells (being rather more vague). Also when for some reason failed to position (being out of range of Network Cell), the phone started to not enter Deep Sleep Mode and the battery started to discharge at high speed. Google Maps, Google+, 1Weather ... were unable to obtain the current location or showed the last known location of hours before. Rebooting the phone sometimes temporarily solved the problem, but sometimes not.
I tried to change the placement options; abroad, with "high accuracy" mode, the location worked well, but indoors the GPS was not able to find satellites (logical) and still the same problems. I enabled and I disabled the location, nothing. Factory reset, no change.
To rule out a hardware failure, I returned CM10.2. Everything about the location worked smoothly... Return to CM11, again the same problems.
In short, my impression is that this is a software bug, as in versions prior to v4.4 Android location "Network & WiFi" + "Scan Always ON WiFi" works correctly. Moreover, not only occurs in the Nexus 5.
I have marked with a star your ticket.
I'll keept testing.
I get this problem when I use tether with WiFi always scan enabled.
When I disabled tethering, I have to manually enable WiFi to fix the location reporting issue.
With WiFi scanning not enabled, I do not get this problem

I think I have similar problem and I really hope smbody can help me.
On my stock nexus 5(4.4.2) wifi location don't work in google maps and ingress, when I turn it on instead of gps location.
But in other apps wifi location works( yandex.maps, 4square)
Only reboot helps
Hello again.
I just updated Google Maps to version 7.6.0 and Google Play Services to version 4.2.39 and all the problems I had with the location are gone, everything is okay again, as it did in CM10.2. So it looks like it is confirmed that it was a software bug.
Sorry, I know this post is quite stale, but I came across it doing a search about this very same problem I've seen on my LG G4 (stock). I have a Tasker task that uses WiFi near state and I use the "Allow Wifi scanning..." option in my Advanced WiFi settings. Whenever I would use WiFi tethering and then later turn it off, I noticed my Tasker task would not detect the WiFi networks it was supposed to. If I turn the "Allow scanning" option of and back on, or just turn on WiFi altogether, it starts working again.
So, after more than a year and a half, and on a newer version of Android and it still doesn't work right. Who knows; maybe it's a Tasker problem.

Wrong location when using high accuracy

I'm running stock 5.1.1 on the LMY48M build and when I have high accuracy enabled in location settings, it shows that I'm in Houston, TX. I'm on the other end of the country in Michigan though. If I go to Google Maps, it shows my correct location. It also shows the correct location if I switch to Device Only in location settings. But in Google Now and Chronus, with high accuracy enabled it shows Texas. Has anyone experienced this before? I've searched all over and couldn't find any information.
E: Also, I'm on Verizon.

i have seen this before, but not nearly to this extreme. the wifi location is being preferred over the gps, and the wifi is wrong, so you get whats happening to you.
we never did actually fix it. you could try clearing cache's and see if that helps.
ist not a solution, but keeping device only on is really the best option if you dont need the wifi. gps is going to be far more accurate alone, the majority of the time, unless you are in a building or somewhere gps has trouble seeing the sat's.

That makes sense. I just tried with WiFi disabled and it still showed Texas, so I'd guess it's Verizon's network causing the issue. I like keeping High Accuracy on for navigation purposes, but if there's no real solution I'll just switch to Device Only. What apps should I try clearing cache for?

i would clear them all through recovery.
the inherent problem with wifi location, that is unfixable, is wifi has a range. usually between 100 and 500 feet in any direction, depending on the power of the router. so any time its relying on wifi, you will always have that range of possible error. where as gps is directly between your device and multiple sat's simultaneously.
also while wifi location is on, google is constantly causing a nlpcollector wakelock, as it records connected wifi to its servers in an effort to build its database, at the expense of your battery and data.
