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

Ever since the latest updates, our GPS Location service has no longer been functioning. Unlike before where the GPS + Data updated me of my location in real time, now the GPS shows "No Service" or "No GPS" (Waze), Ive tried numerous GPS Apps like GPS test, GPS Location fix, and so on to no avail of a fix, it also shows No Fix on GPS Test (Meaning that it doesn't detect any GPS Satellites) unlike before. When I was on the very first stock rom firmware, my GPS locked immediately at the same time updated me in real time of my location, whereas now, without GPS my location skips from one place to another as it base's my location through Data connection.
This isn't only for me, I have three other friends as well who own ZE550ML's (As we bought all at the same time), and this is our biggest concern right now as we travel with a car.
Any manual fix or latest update for this will/ shall be greatly appreciated.
P.S.
• I have tried flashing the latest firmware as well and still my GPS wasn't working. We all tried.
• I've also tried asking via ZenTalk to no avail...

Unable to fix satellites for GPS

I've tried a bunch of things from the GPS tweaks provided in the sticky (To help reduce the lag) and also hard resetting twice. I'm still unable to fix onto a single satellite as google maps keeps saying "Seeking GPS Satellites (0)".
After hard resetting (both times) the first thing I did was turn on 'A-GPS' and than ran 'QuickGPS' to downloaded what was needed. Right after I'll open the HTC GPSTool' to open the port before opening up Google Maps to let it run for more than 10 minutes on both hard resets yet it is still unable to lock on to a satellite. Even with the GPS off google maps is unable to triangulate me to the right position (it's always off by two streets or so). It's just very frustrating and making me wonder if it's a hardware fault. The same thing occurred when I was using the stock TMO Rom. Also on 'GPSTest' it stays at "GPS Starting Up" with just all red bars and nothing moving but the numbers on the bottom.
I'm on a T-Mobile US Touch Pro 2 flashed with EnergyRom (Genesis) (23016). I've tried both 2.1 and 2.5 and Google maps just pinpoints me to the same location (two streets off).
Any help would be great as this is my first smart phone and first time introduced into the xda world and have liked the experience thus far.
Thank You!
*Sorry if this is the wrong forum to put this in. You may move this wherever it needs to.
Did the GPS work with the stock ROM?
No, the stock rom did the same thing my current rom is doing. It's just pointing to a location two streets away nor was it able to get any satellites. :l
I used these registry settings on my stock sprint.

BTW, if I understand this correctly, you don't need to configure any ports or do anything special to use the internal gps. The only thing needed is to make sure that the location setting is turned on (the emergency locator option in Settings/Phone/[your network]/Location-Get settings.)

Google Maps 4.0 Unable to locate Satellites

I have downloaded the 4.0 update. Now I get a Weak GPS signal alert after it searches for roughly 10 minutes.
I have tried all Com0-9 ports, hard resets, and uninstalling/reinstalling Google Maps 4.0
I have the US Cellular HTC Touch Pro 2, WM 6.5 pro, running the standard ROM.
Is this a HTC hardware issue, Google Maps issue, or USCC tower issues??
I had no problem finding 8 - 10 satellites with the old version.
Using my Tilt2 with stock ROM, Google Maps 4.0 got a fix for me.
GPS is a piece of garbage for this phone, at least for me,
It just never worked again for me since the stock rom (always says seeking satellites 0)
Alos,
"My location" is always is in the same spot (I can be miles away and says i'm in the same place)
I haven't done any research on this two issues, maybe some has my problems too?
Well maybe you should try this.
After I flash a new rom to get gps to work I have to do this.
Run "htcGPStool"
Leave phone outside for about 3-5mins until it gets a lock. After that my gps locks in 30seconds or less
ps, the baud rate for the tilt 2 is 57600- com 4
try the link in my signature for the aGPS cab.
This enables aGPS and changes the servers from the public ones which are configured on HTC (and many other devices) by default to the nokia ones which are maintained better and lead to a faster lock.
After installing the cab, run and update/download QuickGPS and make sure you have a data connection enabled then either try google again or htcGPStool or any other gps utility and see how fast you get a lock then
initial lock might take up to a minute, but locks after that come almost instantly.

Why does one need a data connection for GPS? OK, for Google Maps, yes, but just getting a fix doesn't require one -- or does your CAB do something that /does/ require a data connection?
A while ago I read people enabling bluetooth to get GPS working. Yesterday I disabled the cellular phone and it looked like GPS was locking after this. Not a fix if you ask me anyways...

you need a data connection for aGPS. GPS itself does not need one, but the a in aGPS stands for assisted where it uses your data connection to connect to a server to locate you more precisely.
(My understanding of this is that basically your device sends info to the server about which cell site towers are near you, the server uses this info to tell your device which satellites are best for your location, so your device isn't just looking for every sat. its looking for specific ones.)
Here's the wiki for aGPS
http://en.wikipedia.org/wiki/Assisted_GPS
Theres also a bunch of websites with more info regarding aGPS but its best to have your data connection enabled if you want to use aGPS.

Is "htcGPStool" QuickGPS on the programs list?? If not, explain thank you. As for the baud rate, etc... are you talking about the GPS hardware port? My settings say (none) and Baud rate: 4800???? This I have never messed with, could this be the problem??
ATT Tilt 2 w/ stock ROM...Loaded google 4.0 today with no connectivity issues. I normally able to locked my GPS signal in seconds.....

No, "HTC gps tool" is not the same as QuickGPS and it doesn't do the same thing.
AFAIK, QuickGPS talks to a server and gets info on where/what satellites should be visible for your location, your location determined from triangulation (or some kind of location) of nearby cell towers.
HTCGPStool uses the GPS functionality of your phone in some way that helps subsequent lock on satellites. Honestly, I don't know exactly what/how it does -- but it's not the same as Quick GPS.

Ok, where is htcGPStool??? Looked through the settings and have not found anything that directs me to HTC gps tool.
I have an "external GPS" icon that directs me to GPS settings allowing me to change GPS program ports, and the GPS hardware ports.

awesome, It locates me just find just doesn't find any satellites. Then I get Weak GPS signal screen.

QuickGPS downloads the ephemeris data so that it can predict where the satelites are, which ones are visible, and which ones to use. From that data it is able to get a fix faster. There is no fix derived from ephemeris data, and any GPS will work without it. The GPS device in that case must basically just scan channels and listen for enough data to get a fix.
That all said; no problems here with Google Maps.. If I'm inside I'll often get a location approximation based on cell ID's and whatever goes on behind that location calculation and depending upon how the building is constructed I may or may not get a GPS signal eventually. For example my house, no problem, I might see the approximate location for 10s then the real GPS location. At work with heavy beamed roofs and several layers of metal between me and the sky I'll never get a signal inside except beside a window. If I'm outside, I nearly immediately get a GPS fix.

As far as I know HTC GPS Tool does nothing except allow you to basically reset the GPS, ie: perform a warm or cold restart on it. Perhaps this will help, vs rebooting the phone, if GPS is not behaving. I very rarely will find the GPS is simply not functioning after a reboot.
This tool also might let you change the COM and BAUD but you would not likely need to do that on a phone with a built-in GPS. Even if you were using an external bluetooth GPS I'm not sure you'd want to change the COM/BAUD here, you'd simply use the COM port you set up with that bluetooth device.
That all said, the only time I don't get an immediate GPS fix in Google Maps is if I'm indoors. If I'm in a light structure, like my house, I'll get a cellular approximation for 10-20s. If I'm at work with many beams and much metal above me I'll never get a fix inside.
Let me try to be more specific.
1. When utilizing the app, it locates me within 3100 meters. (pressing the blue button, lower right hand corner)
2. After about 10 minutes of the upper right hand corner stating "seeking GPS satellites (0)" the screen gives me a Weak GPS signal message.
3. I have tried changing com 0-9 ports, with no luck.
4. GPS is enabled
5. I have hard reset the device and reloaded all my working apps.
6. I have uninstalled/reinstalled Google Maps 4.0
7. I have tried different locations throughout Northeast, WISCONSIN.
8. I have tried it while utilizing WIFI. No luck
9. I have tried the Bluetooth remedy. No luck
10. Waiting on replies from HTC, USCC, and GOOGLE.
11. XDA so far is the only place with anybody responding.
HTC Weather TAB
Just got done talking to a USCC tech rep.
He has stated that he is unable to give any technical help with the Google Map app. (no kidding sherlock) He was not even of any help when it comes to the GPS settings, but he did state I am the second person that he has talked to with the same problem.
Now to see how quickly HTC, or Google responds.
The only worry I have is not knowing if it is a hardware issue that should be corrected by HTC. I noticed the HTC WEATHER tab works fine. is this using the same GPS settings as the Google Map app??
also, I have been holding out on the aGPS cab posted earlier. If, and when, I use this fix I will post the results.

HTC GPS Tool is not a standard app. Some cooks include it in their custom roms. I don't have a link for it handy, but if you search on the forum boards for "HTC GPS Tool" you'll find it.
That said, I don't know how important it is anyway...
ok, talked to an HTC tech. We checked the settings and these where adjusted. Still nothing. Got rid of Google Maps and tryd BING, and still nothing. HTC TF3D Weather tab seemed to update just fine, this gave the tech a reason to dump me on MSN and Google. Do you really think BING and GOOGLE share some programming similiarities????
Did you run Quick gps? That did it for me when I first got my phone.
It is installed under the programs lists.

I think they both access GPS via WM. Maybe HTC Sense (Weather tab) directly access the GPS?

GPS locking time - my suggestion

Hi all,
after upgrading to JB 4.1.1, my GPS performance was terrible.
I tried every post available on different forums doing:
Flashed 4 ROMS - didn't help
edited and swapped 4 gps.conf files
eventually one thing made the difference.
I unmarked the "Google's location service" under the Location services settings.
now the GPS is locking in 5 sec.
I hope it will help you all.
Morris
The reason why the GPS isn't working well is because Google pushed out some bad A-GPS data, not necessarily related to you flashing 4.1.1. It seems to be fixing itself now, and you should be able to re-enable Google location services. Especially because the location services is required for many apps to get your location, such as Google Now.

GPS doesn't work

Hi,
the past Sunday I was biking, as I usually do those days, but the tracking app I use can't get the loc in any moment of the ride. I thought it possibly was a sporadic problem, but I've tried many times with many GPS apps: gps status, google maps, endomondo with no luck. Then I expected it was a rom problem, so I changed it to a lollypop rom (blisspop) from StØck ROM Sense 5. But the GPS apps still fails to get my actual position. No sats were found, the agps data is correctly downloaded.
Is my GPS dead? How can I know it?

GPS not getting a fix (HTC One M9) but seeing satellites, GPS.conf file

Hi – I've recently started using a HTC One M9 (himaulatt, developer version). I've realised it won't connect to any satellites and so navigation doesn't work (not accurate enough just using mobile data to track my route). It was originally on MM but I went through all the OTA updates to bring it to N (7.0), version 4.30.617.12. I then unlocked and rooted, installed lineage 14.1 and all seemed well until I spotted the navigation issue. I tried the latest Venom ROM that offers some GPS initialisation. I've now returned the phone to stock 4.30.617.12, again with no improvement.
I've followed all the steps for resolving I've been able to find, including at https://www.technobezz.com/fix-android-gps-issues/ - and I've been using the GPS Status & Toolbox app as well as GPS Testing Tools. I've repeatedly cleared AGPS data and downloaded it again using GPS Status. I've removed other apps that access GPS and cleared cache on those remaining (Google Maps, and the two mentioned above).
The apps report very occasional single satellite fixes being made, not sufficient to help with positioning. The phone detects that there's as many as 25 satellites in view, once AGPS is loaded, but doesn't use them. On GPS Status, some are reported in blue (“only rough orbital data (almanach) is available”), and sometimes some in yellow (“all orbital data is available, but the satellite is not used” - THIS IS VERY PUZZLING). Another phone that works well with GPS reports the same / similar satellites above, with compass giving a 10deg different result even after several rounds of calibrating..
I'm now looking at the GPS.conf file, have tried several available online for UK, and have edited it myself in response to online advice. Any tips? The one given via stock has the following last few lines, does it look OK? )...
SUPL_VER=0x20000
PHONE_TYPE=UMTS
CAPABILITIES=0x33
Advice very welcome and appreciated – otherwise I'll have to sell it on with the fault declared, probably at a quite low price.
Many thanks, Geoff
Flash back to stock and start over. Its a bug. The other symptom is false location reports.
