Simple Solution for Xperia M GPS - Sony Xperia M

Hi,
I was following another post about fixing the GPS issue of Sony Xperia M. I also have a C1904 which behaves as how other users reported about the GPS issues and possible fixes. I haven't follow actions suggested by another thread as it seemed to involve quite a few things.
Recently I found that the phone GPS is working fine at least for a couple of weeks. So I ponder what has been changed:
1. enabled developer options as I would like to enable mock locations to use Bluetooth GPS receiver.
2. enabled mock locations
3. installed Bluetooth GPS from Play Store.
4. rooted.
I think steps 4 might not be required. So if anyone can try the first two steps to give feedback on whether they get their GPS working more robustly.
I am happy to see this fixed in your phones.
Cheers.

After trying your Tipp (only enabling mock locations) for a few days now I think I can confirm this but have to test on in narrow streets and woods...

Thanks for testing yours. I think rooting is not needed as you say. So I think enabling mock locations and disabling network location are essential..

So checking this option on Xperia M will improve work of inbuild GPS? I must try it!

The real guide for xperia m gps issues:
go to ebay
buy external bluetooth gps reviver
pair with your phone
enjoy good working gps

the stamina mode
hi,
today I observed that if I turn off the stamina mode the gps works fine, and it was working properly wen charging because in this situation the stamina mode is turned off...

[Q] Are GPS and videorecording compatible ?

I found the strangle problem with my new HTC Desire HD: GPS lost satellites in the case of camera in the video recording mode.
First concern arose when using the device as a DVR: VideoReg, DailyRoads Voyager, AutoGuard. In all cases I have gps data loss.
As an experiment I ran the program gpstest and the original camera software - GPS have problems with the satellites when camera is recording video
What could it be ???
Factory firmware with OTA upgrade.
The GPS is only active when an app which uses the GPS is active. So if you switch to an app today does not use GPS, the function is turned off.

I understand it of course
DVR's are using GPS and camera by self, in the tests I used gps application in the background (navitel navigator and GPS status).
Oh I see. I don't know what's wronng. Never used any of the apps you mentionned above.
I am the developer of DailyRoads Voyager. There is quite a large number of users who run Voyager concurrently with navigation apps, without having problems with the GPS fix. But, not on the Desire HD
I have made some extensive changes in the code which handles GPS. Would any of you like to test this new version?
Thanks,
Robert
i would test if you send it to me?
just found it in the market and downloading it.
The version on the Android Market most likely has the same issues described above. The new version for test can be downloaded from here:http://dailyroads.com/voyager/test/4/dailyroads.apk
Please test for at least 2 minutes, because listening for GPS will be restarted after 30 seconds, and then again after 1 minute.
This version also creates a log file (DailyRoadsLog.txt) in the root folder of the
SD card. When you're done with the tests, please send this file to [email protected]
Thanks,
Robert
Did anybody resolve the issue? I have the same problem with my Inspire 4G. When the camera is active the GPS wont't fix. Once the camera is off the fix occurs immediately
hi, same problem (still) here. no programm works when it combines camera/GPS.
just installed DailyRoads Voyager and will try 'n' see if I can do the tests and send the doc. maybe it'll help.
PS contacted HTC a while ago, simple reaction "your GPS is working as wel las your camera. you don't have a problem then...." welll, discussing here is more than limited, even when sying tt both together don't work...
Hi, found via Robert (daily road travel ) found via russian forums the following : add an external b/t gps receiver, download a small app from the market which links the receiver to the phone and done !
Ok, it's a workaround but a working one !

gps not working after the forced mango update

There's a problem with gps on my phone Samsung FOCUS ,Gps is not working even in the open sky, tried several app like -> gpsinfo,wingps and others like RunKeeper,RunSat etc
Phone is Dev unlocked as well as Interop Unlocked with internet sharing enabled.
The update was done using forced method.Updated from stock firmware->7008->7032->7043->7720.68.
Versions ->
Diag app-> 0103
firnware - 2103.11.8.1
hardware rev. no. - 3.1.0.7
Bootloader ver. - 5.8.0.2
radio software ver. - 0.0.0.3
Please help?
Microsoft released a statement saying they don't blame people or doing the forced update... it doesn't do anything bad to the phone so I don't think that's the issue. You might want to try rolling it back to nodo, checking your gps and then reloading mango. if still no go. Hardware issue maybe??
Issue solved,thanks anyway
So, what was the problem?
Don't know, flashed mango again.That's it.
Gps locked in under 10 sec inside the room.
Hmm. My GPS will find my location fine but getting directions is terribly slow now and turn-by-turn will always just say "can't connect to satellites." Now I'm wondering if a rollback and updating again to Mango will fix this.
I'm on official Mango on an AT&T Focus (and I didn't force the update), and I'm having problems just like the previous posters with GPS fixes and 'can't connect to satellite' errors when trying to get directions.
I found a solution by going into another application that uses GPS, getting a GPS fix in there, then going back into the maps. The program I use is "GPS & GPX Logger." After that finds the satellites, the maps work as they should.
For background info, my phone went from NoDO->Mango Beta 2 (7661)->Mango Beta 2 Refresh (7712)->Unforced official Mango including "Samsung Update"
I tried the turn-by-turn again this morning and it actually worked. This is the first time it has since updating last wk. I didn't change a thing, so I have no idea why it work suddenly.
GPS works on Samsung Focus even after Tango update
I own samsung focus 1.3 (AT&T). I purchased it in the beginning of Sep. 2012 (quite late). As soon as I got the phone, I connected it to Zune for updates. After having updated to 7.10.7720.68, I started using the phone. The GPS did not work. I then updated it to 7.10.8773.98 with the hope that updates may make GPS working. I tried all possible tricks available on XDA as well as other forums. I tried following tricks with various permutation & combination:
(i) Pulling out the battery for 30 minutes.
(ii) Changing the MOLR CP/UP setting in GPS diagnostic to UP and CP (one by one),
(iii) Rebooting the phone with location off & again rebotting with location on
(iv) Apps like GPS info & others
& few more which I do not recall now.
After having tried for about a month, I reverted back to original OS version 7.0.7004.0 just to ascertain the availability/ functionality of GPS hardware as on some of the forums I read that their GPS stopped working after No-Do updates. The GPS did not work even after trying all above tricks on 7.0.7004.0 version of OS.
Finally I accepted my GPS to be faulty or not being there and again updated to latest OS version.
One day I read on some forum that putting off the location service & then switching on makes GPS working. Wow, I tried it today, IT WORKED. On bing map it locked, initially with a bigger circle & then reducing down to a dot. In areas covered with thick trees or high-rise buildings, the circle used to become bigger but again in clear sky area it used to reduce down to dot. I am keeping my fingers crossed. Let me observe for some more days to ascertain that this trick actually works.
Those who have not been able to make their GPS working with other tricks, please try this & let us have your feedback on this forum/ thread.
GPS not reliable
In continuation to my previous post, the working of GPS is not reliable. It sometimes works very fine & some times doesn't work at all during the entire journey of 15 Km. You cannot depend on this GPS for navigational aid. It appears to be some software issue. But anyway, I am happy that my GPS is not faulty. Hoping for some fix in future which will make GPS work reliably.

GPS working perfectly for me with my Nokia 800 with Nokia Drive.
Some cars have some sort of coating on the windscreen which sometimes blocks GPS, although I wouldn't expect that to be on US cars.

The issue is not related with car glasses as I have tried a lot in clear sky on foot. The issue seems to be specific to Samsung focus drivers.

GPS on Archos 101G9

anybody can use gps on archos 101g9? can't get no sat fix. app gpstest does not show any satellite. is this a further bug in ics?
running rooted ics 4.05 for sde (surdu_petru).

mmh, where is my mistake? can't get gps lock with google maps, navigation and so on. car navigation is impossible. gps search is endless inhouse and outdoor
settings location + security:
"use wireless networks = off"
"use gps satellites = on"
"use location for google search = off"
edit:
found this in another forum

The same with my device at first.
I used the rooted ICS 4.0.5 and GPS Status from the market and started some experiments.
There'd been no response from the GPS part at all.
After some time i used a serial port api tool to directly connect to ttyO0.
Though the GPS part uses some hex protocol i had been able to get a response from the chip, but it was not human readable.
So this way i made sure there's no hardware damage on my UART interface or GPS chipset.
Afterwards i did some hard resets and checked settings of the UART by typing:
Code:
stty -F /dev/ttyO0
I started to run GPS Status again and also deleted my AGPS data by using the tools menu. Then i changed GPS Status setup to stay active and prevent device from sleep.
I took a while, but then the first satellite came in sight, still no fix.
Next day i did the same after some time more and more satellite where seen, but still no fix.
I restarted my device again to boot stock firmware.
Same again... more and more satellites became visible... but then... suddenly a fix. In fact it took very very long and i'm not very satisfied with the situation.
After i re-booted to rooted firmware again i was able to get a fix here as well.
The signal reception is still far from being nice though.
Try to get a fix with stock firmware first, then reboot and check again with rooted firmware.

Should be no problem with this setup.
AFAIK, these three settings address different services.
GPS should be set of course.

Nice thread, but people start to mix things up at some point.
Though the GPS and location service on Android OS is quite mystic, i'll try to concentrate on some facts.
Hardware:
- NL5550 chipset used on Archos Gen9 is up to date and not that bad
(merged into WL1283 chipset, see http://www.murata-ws.com/com7.htm)
- Due to hugh shielding areas, GPS reception is not the best with tablets (if compared to handsets).
- GPS antenna and position of the antenna seems to be problematic
Software:
- Firmware setup changed form HC to ICS
- size of the patch file for the chip had grown in ICS
(mabye they wanted to make thinks better, but they got worse)
So what could be done...
Hardware:
- I started searching for a better antenna to be placed in the housing
(e.g. helical/helix antenna)
- Place a HF-connector on the mainboard to use an external antenna
Software:
- Extract the firmware files from HC and try this setup for ICS
- try to find other devices based on the navilink chipset and compare their firmware setup
Basically GPS works on ICS and things in fact are not related to ICS itself.
Some firmware tweaks might be the cause of these issues.
The basic construcion of the hardware could have some side-effects on this as well.
Some people seem to have no trouble at all, so at least GPS reception is of course little bit depended on the weather and the area you live in.
I may post the HC firmware files here, if you like to try the HC setup on your device.

GPS lib loops
Hi,
I can ONLY get my GPS to lock on if the wifi and location services are enabled and working.
This is because, the gpslib tries to speed up the lock and position information by going out on the internet and firstly fetch the time from the main European ntp server.
Looking at the system logs, it appears to get into an infinite loop waiting for a time update.
Therefore my gps WILL NEVER WORK if actuated with NO wifi.
However..... If I start the GPS application, (I am using mmaps) with the wifi on and the locaation services on I get a good lock, with 10-12 satellites with the Archos INSIDE my house, within a few minutes. (There is nothing wrong with the sensitivity of the GPS engine!)
If I then stop the app and turn off the Wifi and location serves and restart the app it will get a lock in a few seconds and stay working until I power down the Archos.
This is OK apart from the problem that I want to use the Archos in my car with no wifi.
cheers

Yes, thanks for pointing at this.
Try to disable automatic time sync in time & date settings menu and check again.
You should definitely get a fix without setting the other location services or having wifi enabled all the time.

big thanks for descriptions!
seems like a complicated science for a simple functionality
my older external sirf 3 receiver need only 5 minutes for sat fix after cold start (very cloudy!) and 10 up to 15 seconds in warm state. i wonder why the archos is much slower.
ok, i will give a new chance an try it again and again and again...and report later.

Assisted GPS !!!!!
Hi,
Unfortunately The Archos uses assisted GPS
I am not allowed to post links yet so see:- the wikipedia entry for assisted GPS
The Archos "might" use the Qualcomm chipset "GPSONE" , I am not sure but a lot of phone makers use it:-
see the wikipedia entry for GPSONE
Like I said in a previous post in the other place, I wish Android tablets were not still so mobile phone centric.

Archos uses TI NaviLink chipset. GPSONE is Qualcomm only and there's no Qualcomm chip inside our units.
TI NaviLink supports AGPS as well but it does not rely on that.
In other words even without assisted data you'll get a fix... sooner or later
Assisted GPS is always an option to get faster fix.
Did you try again with disabled automatic network time setting?

libgps loops!
Hi Scholbert
Thanks for correction re type of gps chip. Why I thought there was a GPSONE chip in the Archos was because the /etc/gps.conf uses the Qualcomm extra server site , see below.
However I still maintain there is an infinite loop in the ICS (or Archos modded) libgps. I have left the machine on for 8 hours and never got a lock without wifi.
I cannot post the /etc/gps.conf and the log here because I am too noob yet.
Instead have a look at my post here:-

I guess you're right... I made some further tests and must confirm, that i observed the same behaviour. This in fact is really annoying...
The GPS receiver receives satellite information (satellites can be "seen"), but there's no fix without beeing connected to the networks.
This is acceptable. We should contact the Archos developer's, especially user courville who has joined this forum for bug fixing.
He's an employee of Archos and one of the chief developer's, very friendly and helpful as well!

Had a view at this thread and read your posting.
If the described behaviour is compiled in the lib, we can't fix it ourselfs.
Archos needs to fix this problem by tweaking the library.
If it is related to a setup option, we might easily fix it at least on a rooted device using a customized image.
Had anyone tried the 4.0.6. firmware test release yet... maybe GPS got fixed as well.

Since GPS is integrated into wlan chip it may be necessary to power on wifi to power on also GPS part.

On 4.0.6 GPS works exactly the same.
Some observations (GPS Test)
-it takes quite a while to aquire lock even with "fresh" aGPS data
-lock is not stable- it likes to dissapear even if I don't move tablet
-catching new sattelites "unlocks" the lock
-accuracy seems poor- GPS Test didn't report anything less than 80 meters (Xperia Arc S in the same spot has <20m)
I get a lock within 10 seconds with my G9 inside my house. The accuracy has gotten down to under 4 meters. On my particular tablet, it works fantastic. I never had to clear AGPS data. I think this is luck of the draw. Some work great, some not.
My ASUS TF101 has all the issues you guys describe. Unreliable and slow. Most people with the TF101 do not have my issue.
My wife's LG Optimus One GPS works great, locks in under 20 seconds and never unlocks. My Samsung Galaxy Ace struggles to get a lock but can maintain it once lock is achieved.
All these devices are running different Android versions so I agree that it is not a software issue. I tend to believe it is the fact some get better build quality antennas than others making some of the same devices work better than their twins.
i have tested copilot on 3 different archos G9 80s. All have gotten a lock in my house. I have tested one while driving to work and it maintains the lock.
anybody want an archos 101g9 ?????
hi,
i'm back here after testing my 101 and i'm not really lucky
thanks to all here first. i pursued the discussion with interest.
my archos did not work with gps at all!. i checked with gpstest and gps status apps indoor and outdoor several hours/days. no satellites found! nothing, zeroooooooooooo. clear sky, no clouds and NO satellites. i'm alone in the universe
what i did:
- device cold start (many times)
- switching on/off date and time from ntp server
- wifi on/off
- google location service on/off
no idea what happen. this is not my first archos. my older g8 had broken usb ports and was changed 2 times. the g9 freezes very often in cpu state "hotplug", run stable only with half speed and gps don't work. why gps need an internet connection?? i have no 3g stick in my tablet and no wifi in my car. yes, i can connect my phone with wifi tethering but sorry, that's not what i have planned. puuh archos, what do you think what customers tolerate. i love android, but the next tablet should be better an ipad
seems, there is a defect. how can i check my hardware before i put it in the trash?
thanks,

by the way, my htc legend with froyo works great. it beams my to every point i wish!
Sorry to hear all you guys are having such problems with gps lock.
I have an original 8gb 9g classic. I have taken it through Honeycomb and up to the last ICS update. I have rooted it, over-clocked it and it has taken everything that I have thrown at it!
In every case, the gps has been first class. Using gpsstatus from the market, it locks on to 9 sats from inside my house within 30 seconds.
It was originally set to europe.pool in the gps.cfg file and I got a good lock with that. When I changed to rooted custom fw, I downloaded fasterfix from the market and used it to change the gps.cfg to uk.pool. This speeded up the lock and increased the number of sats to 11.
One thing that may help, has anyone tried toggling airplane mode on then off again. Whenever I install a new rom, on phone or tablet, I reboot the system at
least twice after setup and then toggle airplane on/off. This was an instruction in some roms that had wifi issues and I now do it as a matter of course.
It may be worth a try.
I use Co pilot live as satnav and it has never failed to lock on within seconds of being set up.
GPS on G9 still behaves strange...
First of all, thanks for posting your observations.
The GPS issue remains little mystic though

I just got a fix within a minute, yesterday it was a no go!
The device actually needed a reboot before. What is responsible for this locking???
I got the fix by...
- deleting the AGPS data in the settings menu of GPStool
- setting the data update interval to never
- unchecked set system time from server in the device settings
- Wifi and 3G were disabled as well
So it's possible to get satelite fix without network connection.
But something may lock the interface. Afterwards it seems to be impossible to get a fix again... at least things get worse.
BTW, GPStool and the AGPS "framework" of the G9 use definitely different data bases for the assisted data. Maybe this causes locks as well...
So from what i can tell... disabling the AGPS function in GPStool definitely helped to get a fix.

Maybe it's worth a try but maybe it won't help anything.
As far as i can tell, a reboot certainly fixes some kind of lock on the interface.
But as long as we always guess there will be no improvement, nor we'll find the real reason for the missbehaviour.

i guess :
GPS Status & Toolbox (author EclipSim, can delete agps data)
also nice
GPS Test (author Chartcross Limited)
GPS Status (author espresso3389, nice graphical tool but only portrait mode)
btw.
upgrade to firmware 4.06 (fix for increasing gps stability) did not help in my case. only my problem has more stability now. still no satellites in sight. my htc legend shows a minimum of 5 satellites with the tools from above at my location (indoor) but still nothing with my archos. disappointing.
the better way is to check the gps functionality before rooting the tablet (loosing guarantee!). seems a weak point of tablet.
i'm searching for an external bt mouse. any recommendation? the mouse should be bought in germany.

[Q] Which app/process is activating my GPS?

When my phone boots, the GPS begins 'searching' for a lock, which, when indoors, it will never find. I'm trying to determine what process or application is activating the GPS.
Couple of notes:
- The hardware toggle for the GPS is 'on' and I'd like to keep it that way; but I only want the GPS to activate when I need it (e.g., Google Maps, etc.)
- Using AutoStarts I've reviewed the list of applications that startup during boot, and cannot identify a culprit.
To be clear - I'm NOT looking per se for a list of apps that MIGHT be activating the GPS; what I'm looking for is a definitive way of determining WHICH specific app or process has activated the GPS. I do have a couple of logging/monitoring apps which I could use, but it would be helpful to know exactly what I'm looking for.
Thanks in advance!
I use google latitude and that's the only time I experience this. Whenever I'm logged out of it I don't experience the GPS at start up. Just my two cents on it. Might be the culprit for you too..
Sent from my SPH-D710 using xda app-developers app
<Bumping> this question back up, as I still cannot identify the process that's activating my GPS. Cheers!
Having the same problem on a Defy + after an update
Should the GPS be connected one time after the update?
I've run a gps test soft found on the market, connect the gps to satllites. close the soft. close the phone.
When ligthe the phone, ther's no gps icon trying to connect nor gps ticked in preferences.

Hope it will work with your phone to

[New Firmware] 47.2.A.10.80

I found a new rom for the XZ1 Compact.
Until now only a few regions are available. Probably the June patch.

Yep. None for Customized DE just yet.
It also comes a little bit late. Am I right?
The xz1c was released on 7.31.17 and I wonder if we will get more security updates after the two years after the release date.
Flash this yesterday using the FTF found here: https://xperiafirmware.com/sony-xperia-xz1-compact/
Can't really see any difference so far, but also no issues with it
Seems to have improved GPS performance on my end. Connection is still a bit weak, but it catches more satellites and doesn't lose tracking suddenly.
The GPS bug is still there and things have gotten even worse. I use a lot of GPS (Waze) and during the weekend I experienced that three times... I just dont get it how Sony cannot resolve that issue (((

I came across this problem on my XZ1c, but I found a fix.
Go into airplane mode and make sure GPS is disabled.
Settings\Apps & notifications\App info - find Maps
Force stop - Storage - Clear cache - Clear data
Restart phone
Enable GPS, airplane mode off.
If that doesn't work use the following service settings number to go in the gps settings :
on your phone keypad dial *#*#7378423#*#*
Go into service tests, select gps then purge test data
reboot

what GPS bug is this? I can't say that I've noticed anything off when using Google Maps for directions.

Usually it happens when I finish using Waze or Google Maps (or any GPS driving app) and after a while I start it again and then it just does not find any satellites. Sometimes after a few minutes its back but sometimes even an hour waiting does not help nor restart nor anything you can think of. And of course it usually happens when you are in hurry It really p....s me off when thing does not work as they should be, especially when you have no time to waist
Well, everything worked fine couple of days and then I started losing GPS again. Seems that purging test data from service menu is the best solution for this bug, sometimes I dont even have to reboot. Still that is very annoying and one more reason not to buy Sony anymore... zero customer support, all this nonsense preventing people to root their phone, bug after bug that dont get fixed etc. They just don't care about anything after you've made your purchase. I've been loyal customer with 3 different phones for 7 years but seems that current XZ1c is the last phone for me that bears the Sony label. Shame on you Sony.

Has anyone experienced loosing GPS signal after a 1-2-3 hours of Google Maps ? It may be like the device is overheating. GPS is back usually after resetting.
