Hello, I just upgraded from an Evo Shift to the Epic Touch and absolutely love my phone. However, one thing has not been working as expected. On my Evo Shift, I was able to obtain a coarse location fix solely using the mobile network (e.g. GPS is turned off, and I get a 2000ft accuracy general network location). This was great to use along with tasker so that I wasn't having to consume so much battery to get a general location.
However, with my Evo Shift it seems as if whenever I attempt to obtain a coarse general network-based location, it either does not give me a fix at all (your current location is temporarily unavailable) or gives me an incorrect location. When I turn on the GPS itself, it gives me pinpoint fine location, but I'd rather not have to keep GPS on all day in order to have tasker turn on my wifi. As far as settings/mods, I am running stock EL29, rooted (with no modifications), have "Use Wireless networks" checked in location and security settings, and normally turn off wireless when I'm not home.
Thank you in advance for any thoughts or comments.
Bumping this in hopes of an answer or at least some insight.
I know that there are a lot of threads that provide GPS solutions, but those seem to be regarding how to get a GPS lock, not necessarily issues with aGPS.
Thanks in advance.
I just checked maps quickly.
GPS on: 10m accuracy
GPS off, wifi on: 20m accuracy
GPS off, wifi off: 1800m accuracy
Seems like it's working as it should. I'm on Caulkin's EL29 Rom, with EG30 modem. Hmm.. why am I on EG30 modem.. all this flashing back and forth I never checked last time I went back.
my aGPS shows 2700m accuracy.
the center point is also 15 miles southeast from my current location.
WAAAAAAAY to inaccurate lol
The other day I drove 30 miles away and Llama never changed my cell mast. I also work 10 miles from home and my cell mast never changes. So Llama is unusable for me as well. (Since my phone evidently stays on the same cell tower no matter where I go in the salt lake valley)
Hello, thank you for your responses. Since my last post, I followed the fix specified in this thread, which resolved the issues I was having even on a stock rom. IN addition, it did not seem to negatively affect fine gps location, which was ok before.
With that resolved I actually moved to Caulkin's EL29 rom (for battery reasons), and still was able to pull both coarse and fine network location, so all is good.
I guess the resolution is if you can not pull coarse network location via cell tower triangulation (essential for either Llama or Tasker), either use the fix at the following link, or try another ROM:

Hi all,
I'm wondering what is better option in the Sleep Policy for battery life when you have no access to a WiFi network? Sure, sure, turning off the WiFi will get you better results when you don't have access to WiFi but the location features you get from using WiFi.
At work I have no access to the WiFi network which isn't connected to the net anyways. But it works great for getting precise location information when inside the building.
I tried keeping it on "Never" but wow does that kill my battery.
Does putting it on "Never when plugged in" or "After 15 minutes" keep it from searching for a WiFi signal all the darn time which is what is killing my battery.
From what I have seen since I changed it to "Never when plugged in" half way threw the shift it doesn't seem to draw as much power. But I did check my Google Latitude history and it seems to be pulling my location from WiFi instead of the cell tower. All but a few times did it get the location from WiFi instead of the cell tower. So that has me wondering is it still looking for WiFi or just turning it on when getting a location request.
Any help would be appreciated.
Thanks
I am using a stock HTC Droid Incredible.
I would like to have it where when the screen went off the wifi went off, but that could be a problem if the screen keeps going on and off from texts or whatever else. Would probably use more battery starting wifi over and over again.
Ok, I have seen this on 2.3.5 builds of CM7, Deck's ROM and OMFGB. What is going on with wifi on 2.3.5? It's causing some kind of wakelock apparently. Look at the right hand side of the battery graph and compare the "awake" to "wifi" time. I had my wifi to sleep when the screen turns off, so it went away when wifi was turned off. But then if I connect to wifi again with the screen off, it causes wakelock. Is this a known issue? I have tried googling and can't find anything about this. Surely I can't be the only one.
On Sense roms I can leave my wifi sleep policy as "never" and it doesn't cause any issues.
I'm using the CM7 nightly build 180 (2.3.5). I'm using Tiamat Kernel SBC. My WIFI sleep policy is set to never. It's been unplugged for about 8 hrs 45 minutes and connected to my WIFI. It's been on standby for the most part and it's at 99%.
WiFi totally unrealiable on the AT&T Atrix 2 (MB865)

I too am seeing all sorts of issues with WiFi on my Atrix2 (MB865) which is also running Android 2.3.5. As a matter of fact, I have TWO of these, because my wife got one also, and it has the same problems. To be specific, both phones will drop 128Kbps streams and fall back to 24Kbps, if the alternate slower speed is offered. This constant dropping of audio stream is the most annoying problem, but the phone also will spontaneously disable WiFi. After manually re-enabling, it can take up to a minute to reconnect to the AP (the happens at home and at work).
When connected, a speed test might show something like ~100Kbps down. But disabling and reconnecting a few times will help get it back to a good ~20Mbps down again. Sometimes when connected ad showing a FULL STRENGTH WiFi status icon, I am still not able to get any data whatsoever, just as if the WiFi is not even enabled. Examining this with WiFi Analyzer shows that it detects no AP's whatsoever, even while the status icon shows a FULL STRENGTH connection. Again, disabling/enabling can correct this issue.
Just to prove it's not my home AP, I have an old HTC Hero running a CM7 nightly build from 9/1/11 kernel 2.6.29-6 (which is also Android 2.3.5).
My old HTC Hero connects quickly/flawlessly and holds a constants steady 128Kbps stream all day without fail.
Why can't these carriers (AT&T in this case) put out a reliable Android build. I can't help it, but my paranoid mind makes me think it could be purposefully done to force customers to use precious bytes form their costly data plans. They certainly would have no incentives to make WiFi work efficiently.
Anybody got an ETA on CM7 for this phone?

During a recent visit to Korea, I had 0 luck getting a GPS lock, even after using FasterFix to set GPS pools to Korea and Asia, and clearing aGPS each time with GPS Status. I tried stock EL29, stock ICS leaks, AOKP, and CM9. My Toshiba Thrive, however, was able to get a lock without a problem, and my og EVO was always able to get a lock. I can get a lock in airplane mode just fine in the states. Is the E4GT unable to acquire GPS locks outside of the States or is it just Korea? What's everyone else's experience with using GPS outside of the states?
If you had airplane mode on then that is most likely the problem. I experienced the same problem in the UK and New Zealand, for some reason it won't lock in airplane mode. I had limited success with getting a lock with airplane mode off and then turning it back on again, but the only surefire way was to have airplane mode disabled completely. Only downside is a bit higher battery drain as it looks for a non-existent CDMA signal.
perhaps that was the culprit. i always kept it in airplane mode but left wifi and gps turned on. that blows. my thrive and og evo have always been left in airplane mode, so i wonder why samsung doesn't like airplane mode.
I think it is a bug in their radio firmware or system drivers.
I think it is due to either limitation or lazy coding with their use of separate older qualcomm modem/radio subsystem and their own CPU.
I believe if they had more recent pure qualcomm solution and started with qualcomm source base, GPS would work like other phones.
Probably GS3 will have it fixed since it is a pure qualcomm solution.
I was in Korea at the end of March using the EL19 modem and I had no issue what so ever getting an accurate GPS lock. I was able to rome the streets and hillsides only using my phone GPS.
I was activated for voice and data over SK Telecom though. Hope this helps.
The bug we are talking about is GPS won't work with airplane mode enabled.
Why is that considered a bug? I thought the idea behind airplane mode was to shut off all radios that send or receive a signal. No?

It is to disable all radios that send.
A passive GPS receiver is not going to affect anything so there is no reason to shut it off.
Other phones' GPS work fine with Airplane mode enabled.
Also user has explicitly enabled GPS in Airplane Mode.
Gotcha. Thanks for the clarification. On a side note, without following all the other threads, are you getting out a fe22 one-click tonight? I wouldn't miss it for the world.

He's always one step ahead of us.
I used my gps hiking today with cardiotrainer in an area with no signal, airplane mode on. Worked perfectly. Was on stock FE07 sfhub one click.
Sent from my SPH-D710 using xda premium
Was it outside the states? i'm able to use my gps in airplane mode when im in the states. i guess i should've specified that in the first post.
Once you get GPS lock, you can usually turn on Airplane mode and GPS will continue to work. It is just that initial lock where it wants to contact A-GPS servers where it often won't get lock unless you have signal. In this situation you should be able to turn on Airplane mode and have the GPS work in total standalone mode.
that makes sense, but if it only needs to contact those agps servers then a wifi connection should suffice, right?

I don't think these are the Google location servers. I believe they are the snaptrack tower-based agps servers (ie you can't connect to them from arbitrary IP addresses anywhere in the world)
If properly configured (by the manufacturer) these phones are supposed to be able to operate in complete standalone GPS mode. The best time to configure that would be in Airplane mode, where it doesn't make sense to do A-GPS. That's how other phones have it configured.
BTW I saw this same type of bug on Palm Treo 800w
do you think there's anyway to port those configurations to the e4gt?
I think there is a bug in the radio. I've configured NVRAM to specify standalone mode and I still can't get it to work in standalone mode. At first I thought I got it to work, but it was only because my USB cable was connected during the reboot. This somehow left the GPS running even after reboot, tricking me into thinking it was working in airplane/standalone mode.
Back in the WinMo days, there were registry entries where we could configure standalone and various assisted modes, but we found some radios just ignored your settings and some followed them.
Many manufacturers have almost zero interest in fixing GPS bugs. If Google maps brings up your location under some situations, they consider GPS working.
**********.
As I understand it, after switching to "Battery saving" location mode, my phone should still be able to detect a location based on nearby wifi routers, bluetooth, etc.
If I close all apps, then switch to Battery Saving location, then open google maps, I do not get a location even if I am at home in my flat and have a strong connection to my router. This also happens at work, when connected to wifi routers on the tube (live in London), and so forth.
So I can only conclude that for some reason my phone cannot use this method to determine a location. My GPS does work as well as can be expected, therefore I am not certain when this issue started happening, as, in most buildings, I can get intermittent GPS signal, and have pretty much always just left my phone on "High Accuracy".
However, in some buildings of course, I just cannot get a GPS signal at all, so this issue is getting really frustrating. Before I try some sort of factory reset, is this a known issue at all? Or can anyone suggest anything less drastic to try? Or a potential workaround?
Specs:
- OnePlus 3 (A3003)
- Android 8.0.0
- OxygenOS 5.0.1
Thanks in advance!
Try this, go into settings, tap on WiFi, tap on Wi-Fi preferences, there enable Scanning always available, let us know if that helped!
Good afternoon.
Guys, I've been very angry with Google Maps.
When using turn-by-turn navigation, inside the urban perimeter works fine, but when I move to the rural area I have constant problems of "GPS signal loss".
I noticed that by losing the data signal (4G / 3G), Maps stops navigating. Do you have any way around it? Having a GPS dependent data signal is very infeasible.
Thank you.
Have you tried putting the location mode to "High Precision" or "Device only" in the location settings pane? Sounds like you're not using GPS, but cellular location....
I have already tried both modes and in both the problem is the same.
This problem comes from the time I had a Nexus 5, at the time thought was problem in his hardware, but start to be a bug of the Android itself.
Did you install the app GPS status? If not, please do. It will show an overview of your GPS receiving, and download the latest A-GPS library's.
However put the setting of location on Device only. That's important, it will use the internal receiver instead of network masts.
