GPS issues - ZenFone 2 Q&A, Help & Troubleshooting

Hi folks,
Using Z00AD - ZE551ML for almost 1.5 years now... but found out GPS is failing on me recently....
Can help test out your GPS? My GPS seems not functioning well since updated to MM then i downgraded back to LL UL-Z00A-WW-52.20.40.196 and i still find issues with it.... i constantly getting disconnection and accuracy of the GPS is way off... i use GPS Test from Chartcross (go to play store and search for GPS Test)... i'm able to get a fix but the accuracy of the GPS keep changing from 30 - 100 feet... casing my waze and all navi software giving me inaccurate route and locations....
I just want to sure this is my hardware issues or if anyone having the same issues as mine then its a software issues....

I know I'm kind of late. But just noticed it now as I my primarily use my old Samsung S5 as nav device.
Anyway, setting Performance Mode to High and transferring SIM to SIM2 slot fixed the issue for me.
edit - Using Waze and Navionics by the way on my ZE551ML on MM.

Hello , try this mod for fix gps

I have the exact same problem. Sometime after MM bootloader switch I lost all real GPS functions. There are only approximate locations available and no navigation apps work properly. Going back to LP did not help either - even going back to stock. About to have to buy another phone over this issue. None of these mod fixes have worked yet but I will keep trying them just in case.

[Q] Problem with GPS

I have a problem with my Defy.
The GPS doesn't seem to work properly. I've tested it with GPS Status & GPS Test...it detects satellites but doesn't use any of them to locate the cell phone.
A few days ago, I've succeed to get a localization but since it doesn't work.
I've just reboot it so that I'll have the manufacturing settings but, it still doesn't work...
Can someone be of any help ?
Thanks.

Have you tried calibrating the compass in the settings? I had what sounds like a similar problem and I did that it worked for me.
Have you tried going into airplane mode, then using the GPS?
The compass is calibrated.
I've tried to turn on the airplane mode & then to launch the gps...same result no satellite in use, no localization...
I tried the GPS today, no airplain mode, defy was working as usual. I had to wait quite long time to get the fix but then no issues. FYI compass was already calibrated.
Since your defy is able to detect the satellites it should not be an hardware issue, i guess you were using pre-installed gmaps and navigator, have you tried any other software which makes use of gps location? (e.g. TrackMe)

Yes, that's what I think, it shouldn't be a hardware issue...
I tried with the apps GPS test & GPS status which were not pre-installed and it doesn't work either...

I can't figure out what's causing your issue... but, take a look here:
https://supportforums.motorola.com/thread/40896
maybe it could be helpful, second post of cheaplikeafox, he's talking about a gps reset (made through GPS status) which solved the problem. Did you try that specific option in GPS status?
Sadly, I've already tried...arf...I don't what to do.
Maybe I should try with other Motorola phones' owners...

Just to be sure, are you trying to use the GPS without being in "maps" that came with the phone? But on a separate set of installed maps? Except for the link above, I don't see GPS as an issue on the Motorola forums.
If I turn on network nav. and go into maps, my location is off by from two miles to forty miles. If I then turn on GPS it will correct my location within thirty second (time, that is). Turn off network nav., go back into maps and hit location and it corrects within 10-15 seconds using just GPS.
FWIW I just bought and downloaded Copilot live for North America ($5) Shut off data and ran on GPS -- it loaded very quickly. Of course it's pulling maps off the SD, but there was no lag in the GPS.
Same issue here.
Bought a defy (made in brazil) today and no gps (endomondo, gps test, gps status).
I already have a x10, and their gps always works.

When I first tried GPS on my phone it took so long to "kick in" I thought the phone was broken. Finally it did. I later got "GPS status" and it picks the satellites up right away. However, I believe you must have your google maps "Maps" turned on or the GPS won't work in the stock phone.
How much time your gps needed in the first time? I im trying right now.
In google maps: My location: Accurate to 70 meters (wireless method).
In endomondo: Locating satellites
In Gps Test: In view 1, In Use 0, Gps On (yellow), Accuracy (feet): 0
After about 1 hour, i am getting 2 sats in view on Gps test, but no one in use.
After hours, i am getting 2 sattelites in GPS Test (sometimes 3). But the color of the bars (SNR Color, according the documentation) is white. Not working...
On my xperia, i am getting 9 sattelites (yellow and green).
Make sure you're not on WiFi

My previous phone was an xperia x1 too, yes GPS was much much better. More than a issue with defy it looks like Android is not so brilliant in dealing with GPS.
I need long time to get my position fixed (could it be the lack of QuickGPS??), and it seems many apps can't correctly display the satellites while the device is searching for a fix.
It gets better if i have google maps app opened in background.
Finally got gps working.
I made a few things (not sure what work...)
- Factory reset
- Install a bunch of softwares (Endomondo, GPS Test, WisePilot, TrackerBooster)
What work (i think)
- Leave my phone with TrackerBooster and GPS Test turned on, in open space (a bench on a park) for about 45 minutes (airplane mode off, wifi on and connected, 3g on). In the early minutes, GPS Test only find a few satellites (4 or 5). Suddenly 10 satellites appear and change the color to yellow and green (it was white). Working!
Thanks all!
ps: Defy is better than X10. Even motoblur is better than TimeScape (IMOHO).

When i read "xperia" i thought about x1, anyway, i agree defy is better than xperia (them all) except for GPS. With my x1, in open spaces, i got 10-11 satellites in just 2 minutes (without QuickGPS) and it needed about 20 seconds when QuickGPS was working.

[Q] GPS problems. Can't get a fix!

Hi all,
I have the Desire HD for 2 weeks now but I've only yesterday noted the gps doesn't seem to work... It's a complete stock model, no custom roms or radio's. I'ts just never able to get a fix! Are there other people with problems like this? Could my device be broken?
I have installed a app from the market that tests the gps and it finds no satelites most of the time except one time I checked it found 4 with a very bad signal... Even then in Google Maps or the HTC Locations it didn't get a fix.
Any ideas?
Bump! I have exactly the same problem. Any Advice?
same problem
i HAD this problem, but then i left the GPS on for an entire journey. 45 minutes later it had a fix and ive never had any problems getting a fix within a minute since.
i dont think the phone knows what side of the globe its on the first time, so maybe it just needs a loooong time the first time.
Most GPS devices need to download a file known as an almanac. This determines where satellites will be at specified times.
This file can take a while to download as GPS is purely passive. I'm not sure if the DHD is A-GPS (Assisted). This will download the almanac via mobile or wifi data.
This is why sometimes the first GPS lock can take a while.
Try these two programs:
http://www.appbrain.com/app/gps-status-toolbox/com.eclipsim.gpsstatus2
http://www.appbrain.com/app/gps-test/com.chartcross.gpstest
First one is great for diagnostic so it should tell you what is wrong.
I also have the same problem, been driving for about 30mins and nothing..

1st gps-fix is a pain, after it will all get better....search for my posts, you'll see that this has been asked several times (don't want to be a b**ch but, please use the search button as well) and in general, 1st fix takes some time, 2nd is fast (like <2 min).
At this moment, while I thought my gps fix was very bad (and as I own one, if not the, of the 1st DHD batches, it was not abnormal to think that it also had gps probs) it now fixes within 1 minute....
Problematic piece of device for me for GPS.
Got mine a cpl of days ago , downloaded the apps above but still nothing i will give it one more try.

I tried both GPS apps. And immediately after that, I was able to get GPS satellite lock on within 20s.
Guys regarding the GPS, all of us we face an issue. It can not lock the satellites quickly. Especially for the people like me who are HTC HD2 owners as well. I was waiting only few seconds. (cooked rom). We MUST forget that now. It's an issue for all of the android devices. Even with the device of the Nexus. So we must live with that. Sometimes it will lock the satellites in 1 min or 30 secs, some other time in 2-3 mins. I searched also in the internet and i found so many complains regarding the GPS and hopefully not only from DHD users

Yep, I had also that problem but then red at forums that only way to lock as fast as you can satellite is to use first one for locking over internet and after that it's much easier to find satellite. Whenever you have problem with locking or need gps asap first program should provide you with fast satellite find.
Btw gps on dhd is so good that I have sold my old garmin - simply it's obsolete and now I have only to purchase official car holder.
Most of the times is more difficult to get a fix in a speeding car.
In the opposite case is generally faster to get a sat fix.
So I've been using my DHD for 3 weeks now (stock model as well, no root) and here are two issues with GPS that I noticed and have no idea what to do with it.
1. The same problem as described in first post. Every once in a while my GPS just cannot get a fix. I installed GPS Test app. Normally it finds around 6-7 satellites, they are all in use, the yellow indicator in GPS status bar goes green and my location appears on mini-map.
However there are situations when GPS Test says that there is 1 to 5 satelites in view, later on they also apper to be in use, but GPS status doesn't change to green and my actual location doesn't show. It's not a problem of visibility or my location - the GPS can get a fix today and not work tomorrow at the very same place.
I have no idea if this can be fixed, so any help appreciated.
2. This is not really an issue, just something that I find quite disturbing. I'm using this traffic app (Yandex Maps for those of you in Russia). It shows current traffic condition on the map + your current location if you have GPS. So each time I lock my DHD (press the button on the top) the GPS is immedietly switched off. So when I unlock the screen to see the map again it takes from few seconds to a minute or even more to update my current position. Sometimes it doesn't happen at all (see problem #1). I understand it's probably done to save battery but I would prefer continuously working GPS than saving battery. Is there any way to set GPS to always working mode?
Thanks in advance to everyone who can help. Cheers
Hi,
I read all you guys said and after trying both the apps and refreshing my agps data manually I now get 6-7 satellites which is good I think?
So for all of you with the same problem, just stay outside for a moment and make sure you have a data-connection. Then use the GPS Status app and refresh your agps data manually. It should work... It did for me!
Ps. I think my Desire, not the HD, used to see 11 satellites? Is that possible? Does this mean 6-7 is kind of weak?

Just to make it clear - to manually refresh AGPS using GPS Status - you need to go to Menu->Tools->Manage A-GPS state->Download?
I'm not outside now, but will try it once I have problems getting a fix.
And yes, 11 sats is possible. 6-7 is more than enough though.
Stand still to get a fix? Harder when you are speedy, I think.

Your movement speed has no impact on how quickly you get a lock. Remember, these satellites are in orbit traveling alot faster than your 30 - 70mph.

[Q] GPS freeze Ginger Villain 2.1

Hi all,
I have a problem with my GPS signal.
Normally (pre rooted era) I could switch on the GPS and get a fix. No freeze whatsoever.
With Gingervillain 2.1 I switch on the GPS and check the signal. I see several bars before the signal freezes. Tried flashing different radios but this made no difference. Also tried several radio / ril combinations same result.
At this moment I found a sort of workaround by switching on Google navigation and then switch on GPS. Check the signal with GPS Status and u usually get a fix within a minute (even indoor). After that I switch on Navigon to start driving.
It is not really a problem this way but what can I do to solve this problem. When I look in the threads (CM7 / Gingervillain) the GPS problem should be solved. Are there more people with this problem? What could be the best solution.
I have CM7 and no issues. I don't know what the problem is. Could be the rom, could the radio, could be other problems. It is too vast really. The only way you could fix it is to try different roms and see which one works. But like you said its not much of a problem.
Sent from CM7
Thanks for the reply,
Yesterday I switched to the latest radio (32.56.00.32U_5.17.05.08) and RIL (2.2.1003G).
As long as I start Google Navigation first and then switch on GPS no problem. This morning I drove to work with Google and Navigon switched on, no problem (30 min drive). Even switched off Google and Navigon kept the signal, no problem.
Whenever I switch on GPS first it looses track somehow. Can't figure it out..
Is there some keep alive GPS flow in Google Navigation?
No. When you turn GPS on its just on and idles. It needs to be used but I don't get how it doesn't work right. Grab an app from the market, GPS essentials I think and see what you can do with that.
Sent from CM7
With GPS essentials it works, better than GPS Status (think it has monitor function only). Think it has something to do with keeping GPS alive
Tried it from work - home, worked fine. Went shopping same procedure...
Might also be engergy savings mode in Ginger Villain. Batterydrain is less with it I noticed.....
With this working... perfect ROM!!!

[Q] GPS acting crazy

If you're locked into as many as ten satellites is there any reason to have erratic GPS performance?
I got a refurbished S3 from Sprint and the GPS is a freaking mess. I can be standing perfectly still and the map starts moving around erratically, sometimes even straight backwards. Other times I'll be driving and it will show me on a totally different street or moving in a totally wrong direction. Sometimes this is going on when I'm locked into as many as ten satellites.
Shouldn't that be enough to get a good fix? Does this suggest that the GPS receiver is working well but there is a software problem? Or is this a hardware problem that can't be fixed?
I reset/downloaded agps data with GPS Status, I've tried TopNTP and I've tightened every visible screw. Nothing has helped. I also can't get a fix indoors like I used to be able to with my original S3.
Any suggestions on other things I can try to make my GPS work or is this a hardware problem that can't be fixed?
This is the fourth or fifth refurbished Android phone I've received from Sprint over the years and not a single one has worked right. It's like they don't ever really address the reported problem. They just factory reset the phone, give it a cosmetic facelift and then ship it back out without any testing.

What Rom are you using ? Did it behave like this before rooting ?

I'm totally stock 4.3, just rooted. I rooted it pretty soon after I got it so I don't remember if it was like this right off the bat. I believe it was.
Weird thing is that today I tried turning of Google location services and that seemed to help a lot. It doesn't seem to be getting a lock while indoors but when I'm driving around I'm not getting the erratic map behavior I had before. No idea if it will work for long, there have been a few other times when I thought I fixed the problem and it came right back.
I know on my previous phone I had Google location services on and it worked like a charm. Anyone have an idea why turning location services off helps and what I can do to make GPS work right with location services off?
Any real downside to keeping location services off?
I've always kept it on. But if your Stock rooted, and have that big an issue with GPS. I would almost be inclined to say it's a hardware issue. You could always Nand, and flash a coherent Rom. Just to see if it resolves the issue.
TEAM MiK MikROMs Since 3/13/11
After driving extensively with Google location services turned off I did not experience any more erratic behavior. Problem solved but I'd like to have location services on.
Tonight I turned location services back on and it still seems to be working fine with no erratic behavior. I haven't given this as thorough of a test but I'm optimistic.
I have no idea why turning location services off fixed things but if anyone comes across this thread looking for a solution to GPS problems try turning Google location services off and see if that helps. It looks to have done the trick for me.

GPS after Lollipop

Is anybody else having GPS issues after updating to lollipop? I am using the app GPS Status and it does not connect to satellites according to it? It shows 21 satellites but connects to none. Is there anything I can do?
I'm having similar issues. Maps seems to still grab a signal however. Over the past two days it seems to have gotten better, but the sensitivity seems to have taken a nose dive.
I have used gps this morning and it worked. I didn't check how many satellites its connected to but it seemed to work ok.
Same problem here, GPS had been acting up recently, but I tried it on the way to work this morning and couldn't get anything. Tried turning GPS on and off and rebooting the phone, still nothing. I have no idea what else to try. It's set to high accuracy mode, not many other settings to change.
I discovered a workaround, although it's an annoying one, but if I switch my phone to CDMA only so that it's forced to use 3G, GPS works just fine. Switching back to LTE though it will not lock onto any satellites.
Tried it out this morning and had no issues when on LTE
What I felt is that there is some slight gps lag, like if I make a turn, gps will show I made the turn a couple of seconds later.
But no issues with gps lock while on LTE.

Yeah, I saw this under KitKat and now under Lollipop. Not sure if it's a Note 4 GPS issue or a mapping app issue, though - I was going to try some tests using a Garmin unit and GPS Test Plus on the Note 4, both displaying actual Lat/Long coordinates to compare the two (though not sure how well that will work given general GPS inaccuracies). At any rate, there is clearly some lag in the map position display. I don't have any acquisition or lock issues.

Ended up doing a different test. The consistent lag I have been seeing is with Google Maps. Today I did a 46-mile drive on freeways, highways, & surface streets and used Sygic mapping app. Sygic was dead-on the entire trip, showing the vehicle in intersections, etc. at the time the car was there - Google Maps would have been significantly behind. So my GPS seems to be working just fine but there is an issue with Google Maps. And GPS stayed locked-on the entire trip.

Yes I'm having problems too. I always use Google Maps Navigation and since the update it will randomly say "GPS signal lost" while driving. I am on the latest BOB7 stock rooted, fully updated profile and PRL.
