Desire GPS issues (non-telestra)

I've had my Desire for 3 months now (Telus in Canada) and the GPS has been disappointing. It takes minutes to get a lock, if at all and often sees only 2 satellites out in the open. Sometimes rebooting helps but not always... it just never sees more than 2 satellites. Incidentally my friend right beside me gets a lock within seconds on his Xperia.
Is my phone broken? Am I the only one experiencing GPS issues? Does the radio and/or ROM affect GPS performance?

I was having the same issue. . Install GPS Status app from market. Make GPS Satus wipe A-GPS data and download the new data.
Use GPS status to lock (patience) and make it "keep screen on" in the options menu. Keep it locked at least 15 minutes.
Then your problem should be solved. Now I am locking in 10-20 seconds.
If these does not work try to install latest radio and redo the steps

Thanks for the suggestion... which radio do you recommend for better GPS performance?

you may check your gps.conf, its in /system/etc. if you are living in the us for example and your gps.conf contains an eu server, change it to an us server and your lock will be very fast.
i used an australian rom, it had an AU server in gps.conf, the lock was a real pain with it, i changed it to a hungarian server (where i live) and now i have a fast gps lock (within a few seconds, in my flat also)

I'm in the UK and my NTP server is north america, would changing this to a UK NTP server improve my gps performance?
Thanks

absolutely
you should use uk.pool.ntp.org
with this, your gps lock will be 4-10 sec (in cloudy weather also)
if you would like i can make you a small patch which one will change your gps.conf ntp line to the uk server (you can do it as well with adb push / pull, or with root explorer with a r/w mounted /system)
edit: just attached a fix, flash it in recovery. it just changes gps.conf.

Thanks.

here you can find the servers list by their global location.
http://www.pool.ntp.org/en/
NL server info
NL NTP server (add this to your gps.conf)
nl.pool.ntp.org
ah, nvm, here is a patch (flash it from recovery, or unzip the gps.conf and push it with adb)

Thanks allot! Will report about the results soon.

i have to say that the gps-status thing worked better than the gps.conf... no longer is it stuck at not getting locks... maybe 30 seconds at most now.

Hi ekre,
would you mind creating a patch for Norway (no) as well? Don't have a clue what to do to access the conf file and edit it myself...

wow! finally found why my phone takes an hour to get gps lock...
@longice: you dont need a patch. just download and unzip the GPS_FIX-NL.zip . Then edit the ntp_server in the gps.conf (replace nl.pool.ntp.org with the appropriate server found on the ntp site) and push the edited gps.conf through adb. done!

Thanks for the guidance, dexter. But that process requires root, right?

Well I don't think that adb requires root, but I am not sure. You see my desire is rooted and s-off'd so I just edited the file. Better check the adb threads (When I said flash the gps.conf I meant just that , without anything from the .zip) ;-)

what is adb??

Adb stands for Android debug bridge and is a very useful tool for Android. More info here http://developer.android.com/guide/developing/tools/adb.html

GPS, after reboot

Hi there.
I realise my GPS takes longer to obtain a fix whenever i reboot my device. Is this normal to you all out there? =(
If yes, how do you all fix this problem?

yes it happen to me too ..
the solution that works for me is, firstly install fasterfix (download from market) .. and set to custom server : for malaysia --> my.pool.ntp.org
after that, open gps status (download from market), then menu -> tools -> manage a-gps -> reset ... after reset , open back menu -> tools -> manage a-gps -> download ..
then let gps search for satellite , once lock , then you'll get fast gps lock after that ..

Hi hedayat7
Oh ok. I did not think about that. haha. Ok. Thanks for the suggestion!

[Q] MMS and GPS not working on Cyanogenmod Jellytime by randomblame 4.1 R30

Hi All,
I recently updated from "Cyanogenmod Jellytime by randomblame 4.1 R28" to R30. I am unable to sent MMS message since updating they where sending on R28.
Also my GPS hasnt worked on either R26, R28 or R30. I have read a couple of posts in the issue tracker but im still not 100% certain what to do.
Any help will be appreciated
Thanks

HI
My idea for fixing the issues:
1. MMS - go to the hidden menu with *#*#4636#*#* on your dialpad, then choose "phone information", go to SMSC and hit refresh (I suppose it was empty field and after hitting refresh, some phone number should appear there);
2. GPS - go to any file manager with root access, go to "etc" directory and delete "gps.conf" file;download this file: http://derekgordon.com/gps-files/agps.patch.google.build.v3.1.zip and flash in recovery (or extract gps.conf file from the zip and copy it to the etc folder (I did the second in Total Commander and it worked); reboot. After that you should get rapid lock with 5-8 satellites. But don't download new agps data using any app like "gps status" after that - somehow it messes up my gps.conf file and I have to do the steps above again to get a lock.
Let me know if that helped - it's my first advice I gave on xda. I hope it will work with you.

Hey,
check out the Jellytime thread, both of these topics were discussed many times there.
http://forum.xda-developers.com/showthread.php?t=1778202

Hi martinez1,
MMS are now working. Thanks for that. GPS still the same, ill do some more reading in here and I might just do a fresh aahk over the weekend.
Thanks

[Q] Wifi Not Working On Cyanogenmod 11 - T989

I was able to install CM11. Flashed cm11 on 12/7 and everything has been working great. I was able to update everything. On next morning, wifi signal was there but no access to internet. Wifi is on but it picks up no wifi signals. If I turn on/ off wifi doesn't find anything else. And receive WPS has failed error... if I click in refresh.
I have already daily upgrade nightly builds to up to date build (20131217), but success. same issue. Any idea?
If I do a full wipe and then restore a backup it work for a day, then stops again.

I have the same problem. I dropped the phone on the wooden floor, and thought the wifi just broke, but now I'm confident it's because of bugs in cm11
Considering returning to cm10.3
LE:
Installed BeanStalk with no data/cache wipe and WiFi is still not working.

Hi to all
I had this problem and i could fix it.
afret install CM 11, go to this address : settings/wi-fi/advanced/wi-fi region code
and change it to fix. for me it works on Europe.
I hope it be useful.
If it works for you, give me Thanks ...

Will try as we speak. Thanks for sharing.

I just upgraded to cm 11 build .17 and Wifi just doesnt turn on.
It says turning on... and just hangs.
I've set region to Europe to no avail..

I found a solution. Download SQlite debugger from Play Store. Open the app, then open Setting Storage, then setttings.db, then Global, then scroll down to wifi_display_on and edit the value, change it to 0. Reboot and then you should have wifi working again.

The value only reverted the one time, hasn't been an issue again.

This totally worked for me. But it stops, and the problem is back again. Checking the settings.db shows it has returned to 0. (wtf!)
Not sure what to do at this point. It's nice to know it's not hardware.

thanks!

Fixed my network problem by removing ad-hoc network
Hey,
I had a problem when I tried to connect to an ad-hoc network I'd setup. The network settings screen would freeze up on me and then..... nothing. I checked the database settings by adb'ing onto my phone (a rooted oppo find 5 by the way). I checked the values of the settings database as described by others. That didn't work so then went to the file containing connection details of known wifi networks
Code:
sudo ./adb shell
[email protected]:/ $ su
1|[email protected]:/ # cd /data/misc/
[email protected]:/data/misc/wifi # ll
First I start a shell on my phone (sudo ./adb shell), then I change from a regular user into the superuser (su) then I go to the directory containing the wifi connection info.
There I opened the file wpa_supplicant.conf and removed the ad-hoc connection that caused my problems. I've also read about people simply removing the file. Downside of that is that you will loose your painstakingly acquired history of known passwords (but I guess in the end that is still better then not having a wifi connection at all....)
Hope this helps somebody
Cheers!

Thanks so much dude! I was so close to resetting my phone and this worked perfectly! To those of you who got lost on this I'll try to describe it better... Download SQlite debugger from Play Store or on your PC then transfer the apk to your phone and install Open the app, then press 'App' and scroll down to 'Setting Storage', then 'setttings.db', then 'global', then 'name', now scroll down to 'wifi_display_on' and edit the value to 0, make sure you commit this change by pressing the arrow icon in the top right and accepting. Now reboot and turn on your WIFI!

Firmware Update to Marshmallow - GPS Stopped Working

Hi!
I've made a post in the Asus forum, with no luck and I found this page where you seem more technical :
Two days ago I downloaded the Android MM 6.0 update from the Asus Homepage downloading the version WW-4.21.40.144 , since I live in Brazil and the phone was bought here. I followed all the steps one by one till it got updated.
The problem is, since then my GPS is not working (Waze, Googlemaps ans several apps).
I tryed:
1. Giving all permissions of location to the apps
2. Puting the settings in High Accuracy
3. Restarting the phone several times.
4. Switch on and off Airplane mode and 2G 3G ands 4G (I read sometimes its interference from that)
5. Waiting almost an hour with the phone outside (sunny day) to see if it detects the satellites.
6. Every app inthe appstore that promise GPS Fixing (reseting, A-GPS and all kind of tests. Funny thing, the sensor IS working acording to those apps.
7. Factory Reset
8. Factory Reset and Erase Cache from the bootmenu. (as indicated in the Asus Forum)
9. Downgraded to Lolipop again. WW-52.20.40.196
10. Again every app to reset the GPS.
Nothing worked.
To my surprise, now I have Lolipop and no GPS. So back to basics but, worst.
The Asus forum told me to Update to the latest version, which I did:
1. Updated my phone with the latest MM version. 4.21.40.223.
2. Put the location options in "High Accuracy" and permissions needed for the apps.
3. As the old software was installed after that, I tried Waze. No GPS Signal was found.
4. Did a factory reset.
5. Put the location options in "High Accuracy" and permissions needed for the apps
6. Installed the apps GPS Toolbox and Waze again, the both can't find a GPS signal. I left the phone outside for 10 minutes.
7. Tried to install the version UL-Z00A-WW-2.20.40.198-user by bootloader, but it says it cannot update to an older version, which sounds about right. (I had to try)
What else can I do? I don't mind going back to Lolipop, but when I did GPS didn't work.
Is there any chance the new Update wrote something apart from software in the chipset that cannot be undone?
Help please, I really need the GPS!
Phone not rooted.
Thanks!
Juan

After long hours of searching, reading and trying I got it fix. How?
0. Have a full charged battery or have your phone plugged to the wall (except for the USB stuff on step number 2, obviously)
0.1. Make backups of all the info in the phone, because everything is going to be erased.
1. Download the version WW-52.20.40.196 from Asus website.(unless you need the other like CN, JK, etc, see Asus site to be sure)
2. Copy it to the internal storage of your phone in the root of it (not in any folder), via USB.
3. Get to the boot loader (Turn off phone and once is off, push the power button with the Up volume one until it vibrates 2 times. Release only the power button until the menu appears) - Search the forum for more details.
4. Select "Recovery Boot" with the volume buttons and press the power button to confirm.
The next steps are all in the Recovery Menu (once it finishes every step it goes back to the original menu, no alerts, sounds or nothing. So check every now and then)
5. Make a Wipe/factory reset, and wait, it takes some time. (use the volume buttons and press the power button to confirm)
6. Make a Wipe of the cache. (use the volume buttons and press the power button to confirm)
7. Install update from Internal storage selecting the name of file you copied on step number 2 (use the volume buttons and press the power button to confirm). It will take a while.
8. Reboot the system (use the volume buttons and press the power button to confirm)
It will restart with the phone in the Lolipop version and the GPS working fine. Even after the Lolipop updates.
Marshmallow update has a bug, that at least with my phone the GPS doesn't work. Tried reinstalling marshmallow latest version after the GPS got fix, just to prove the point, and in fact, it stopped working again.
Then I did all the steps above again and went back to normal again.
I STRONGLY RECOMMEND NOT TO UPDATE TO MARSHMALLOW WITH THE ACTUAL FIRMWARE VERSIONS AVAILABLE.

I also had this problem with Marshmallow ROM, as the GPS is not working in terms of unable to locate any signal from satellites.
However, I also solved the problem with a method sounds very silly.
I turn on my GPS overnight using an application called GPS Status.
The night I turn it on, it was locating 0 satellite (it will write 0/0 SAT). However in the morning, I found that the GPS is now working, locking on 8 out of 24 discovered satellite (it wrote 8/24 SAT).
Now my GPS is working seamlessly.

Thanks! I will try it next weekend. I need my phone this week. Hahaha
I ll post when I do so.
Do you know other similar cases of people who did that and worked?
The thing is, now I have Lollipop again an I noticed how slow the system is running with applications. I d love to have the update, but not sacrificing the GPS

I decided I won't make the test because it doesn't justify the risk and time.
I'll wait for a newer update or just stay with Lollipop.
Just to let you guys know in case someone was waiting for this

I downloaded GPS Status as suggested by SleepingAran and ran it once. Now my Waze is working seamlessly. Thanks!

There's another simple solution that works:
Follow exact steps:
1. Turn on location and set high accuracy mode
2. Open google maps
3. Move your phone several times in the shape of 8 (8-10 times should be enough)
4. Close google maps and clear it from recents screen
5. Start google maps again. Profit
