Hello,
I am using SGH-i777 outside USA (in Kosovo). I purchased it unlocked so everything works as expected, except GPS. The phone came with Gingerbread (not rooted). I tried GPS through google maps but i was getting "You location is temporarily unavaliable" and the scan was taking ~10 minutes without any results. Applications such as AccuWeather were also not able to find my location.
After this dissapointment, i decided to root the phone and install a custom ROM. I followed the guide posted at this link and followed the steps there 100% without making any changes/mistakes. I installed the Siyah 2.6 Kernel and the ROM that i choose to install was Aberration. I also followed the guides for this and did everything as advised. I turned the phone on but the GPS was still behaving the same. After this, i purchased GPS Doctor and clicked "Quick Fix". After this i downloaded GPS Test to see if the signal was alive, and after ~2 minutes of scanning, GPS Test found around 7 satellites and the signal appeared green within this app. I followed this by opening Google Maps and i got the correct location after ~2 minutes scan. This made me happy and i believed the GPS issue got fixed. But after trying after few hours, i saw that maps was again facing the same issues and apps that require location access were not being able to do so.
And the last step that i did was install a gps fix as posted on this thread. I know this thread states that they do not officially support sgh-i777, but i was out of options so i had to try something else. I followed all the instructions and downloaded and installed the Google Specific v 1.3 from that website. But this did not fix the problem either.
To conclude; the GPS is simply not working as expected. Finding the location takes to long and i was able to get the location in Google Maps only 10% of the time (my old iPhone 3gs finds the location in 3seconds!). I have tried this indoors and outdoors but the problem remains the same. During all the times, Wi-Fi, GPS and Data were turned on
Currently i have un-rooted the phone (followed the guides here) and am currently running the official ICS which i installed through Odin. Tried GPS again and it still does not work.
Sorry for the long thread but i wanted to explain all the details.
Hope someone can help me.
Looks to me like one of 2 problems:
1) You're not getting a good time from NTP server, try downloading FasterFix and selecting your area (need root). Not very likely, since with good GPS you'll still have a fix within 1-2 min.
2) HW problem, possibly antenna contacts.
So any go around for hardware problem?

HW problems are solved in HW. You can't "go around" and make the bulbs light in your house when the power has been cut off, can you? So how exactly can you "go around" a bad contact with antenna, that practically equals a missing antenna?
Just fix it.
In settings under location services did you check "use internal GPS" ?
Not even sure if aberration has that option. Jelly Bean ROMs do.

All the ROMs do. It's a stock Android option, equals to toggling the "GPS" toggle on in pull-down toggles.
And of course if he didn't have it toggled, he wouldn't see any satellites at all.
Plus, the original post is 2 months old. I believe the OP has already solved the problem or moved on.
I have a p760 and I found gps performance are very bad without agps.
To get an offline fix it took 10+ minutes, in the same conditions my old acer s120 got it in less than 2 minutes.

I have similar problem, fix is slow and not stable, even with agps, using nav aps in car is imposible.
I've installed GPS Status to help fix faster but it didnt helped much.
Any one found a solution for this?
I have the same problem, fix is fast but GPS connection is not stable. Tried install another navigation but doesn't work.
If youre rooted try to install this app FasterGPS
Thanks is much better, but not perfect. Connected with 6-10 satellite have low quality signal(in GPS test ~20 SNR), localization is not ideal. Any ideas ? Sorry for my english
Also, if your rooted, I recommend Pimp My Rom (alpha) from the Play Store. It has lots of useful tweaks, but it also allows you to get the correct GPS config file for your country. As my phone was from Taiwan, it would have the config files for that country and not the UK - where I am. Correct location = Faster connection.
You just get the app then move to the 'Tools' tab then scroll to the bottom, One up from that should be the GPS Configuration, choose your region then country and 'Apply Selected Tweak'. It only takes a few seconds and it makes sure your GPS is configured for your country.
Hopefully this helps out.
I just geve up with fixing GPS, i factory reseted the device, and even uploaded software using "emergency software recovery" from LG tool to try all options, but no success.
Today phone was sent to the service center. Now waiting for the results.
==========================================================
Phone is back from service, and it works now
Fix in less then 10 sec and stable.
Service center replaced back side of the phone (not the battery cover ), there are aerials there i think.
I bought HDC Storm MX phone from China. It has MT6589 quad-core (if that changes anything). It had all the chinese apps, but I removed them, and flashed gapps, and everything is working great, except the gps.
It just cant get a lock on anything. After waiting a few minutes, it just found 2 sattelites, but didnt lock on them.
It's rooted, and I already tried changing "gps.conf" file, but it didn't help.
I attached the screen I get, when I am using GPS Status.
I dont know what the second icon from the left side in the status bar means.
How can I fix this, as there are probably no custom roms for this device?
Any help would be very much appreciated.
Thank you.

I found the solution. None of the apps from google play worked. Tried gps doctor, fastergps, gps fix etc.
Maybe "gps.conf" trick works when you get partial gps fix, but it didn't for me at the time.
Even reseting and downloading A-GPS data didn't help me.
In the end, the fix was very easy, I just didn't think of that at first..
So if anyone needs it:
1. screen) Settings -> Location access,
2. screen) Location access -> click on "GPS satellites",
3. screen) Enable both GPS EPO and A-GPS,
4. screen) In EPO Settings check the auto download, and click the Download button.
That's it. It helped for me, I get a GPS fix in Waze now in 3-10 seconds.
I read about EPO, but couldn't find it in the settings.
Hope that helps.
Cheers.
Thank you very much, been banging my head against the wall with this one. I have a mtk6589, Have been using Android since the G1 and I some overlooked the basics...
Thanks !!

Be aware that AGPS and EPO will consume data traffic. Usually not too much - but keep an eye on the data usage for a few days to get a notion of the ammount.
HDC storm mx - howto flash the gapps - recovery mode in Chinese?
I entered the recovery mode hoping I could install the gapps zip file.
But the menu is in Chinese, no idea what I should select!
In fact, the only way I got out of this factory mode was by removing the battery...
I tried to simply install the apps one by one, but the installs all failed.
Advice is most welcomed, but please with the details, if possible.
thanks,
guy

How I did it - I had a second phone with Google Translate installed. I used the option to capture picture and translate text in it.
I don't remember which options from the top I had to choose, but it worked out fine with that method. First I flashed ClockWorkMod (cwm) recovery, and from that point on I had everything in english.
Which CWM for HDC STORM MX
COOL IDEA!
which CWM did you use?

I don't really remember which one I used, but I guess it had to be the one in this file - http://www.putlocker.com/file/79BB23D5D744EC65 (as HDC Storm MX is a rebranded Firefly II)
As the file is big, and I can't check it at the moment, I will download it and take a look in the next hour or so
partial fix
This works to get a quick fix and start navigating...but I have the problem that gps cant seem to keep a lock on. it will show my correct location, and a few secs later its off by a few streets....it will lock on...and lose.
Any suggestions?
it also influences other apps using gps like sports trackers. here something strange(r) happens: it will have mapped my route ACCURATELY, but the distance calculation will be off by A LOT. A 7km run got logged as 55km, a 30km bike ride was shown as 325km. those differences are huge. ive tried endomondo and runtastic - same issues.

It might be related to framework-res.apk
Sometime the OEM modified the map and geo redirection to baidu, user who want to use Google Maps with GPS need to decompile framework-res.apk and change the following properties to
<string name="config_networkLocationProviderPackageName">com.google.android.location</string>
<string name="config_geocodeProviderPackageName">com.google.android.location</string>
in res\values\strings.xml
Did you find a solution for this ?
I have the same problem

another variation
I have a similar problem with my Star N9599T (MediaTek MT6589T SoC) in that it has 11 to 31 satellites 'in view' but fails to get a lock.
I have
* used fasterGPS to modify /system/etc/gps.conf
* permitted access to location in settings
* activated download for EPO & A-GPS in settings
* deleted /data/misc/mtkgps.dat & rebooted
* tried several things in MobileUncle>engineer_mode>location
* reset A-GPS in GPS Status
The satellites in view in GPS Test never change from 0.0 signal strength, even with 31 satellites in view.
/storage/sdcard0/GPS.LOG (covering several days) shows about 7 seconds with a lock.
The NMEA log shows what appears to be a lat/long position that stays stable to 0.001°
If anyone can point me to instructions for MobileUncle 'location' or gps.conf I would appreciate it, or if anyone knows what the actual problem is that would be good too
[update]
I unscrewed the inner back cover & checked inside. (just the black screws, but there is one under a tiny sticker at bottom right. Leave the brass one under the SDcard)
It all seemed clean but I blew gently through it all anyway, then found one slightly loose screw which I tightened.
Put it all back together (inner back cover is really awkward to get properly seated) & it works!
It was very slow to get a lock & I reset it several times before it would lock, but it held the lock while walking & got it straight back after I'd been on a bus. (using My Tracks so i can look afterwards)
One thing that it didn't like was switching to GPS Status & back again, it lost the lock for over a minute & was wrong by 25 metres when it got it back. I walked for 50 metres before the accuracy came back.
My HTC Wildfire S can also be slow to lock occasionally so I'm hoping it will be ok now.

Hello,
I own a THL 5000 (chinese manufacturer).
Because the stock ROM didn't work (reboots in standby mode) there's a ROM installed, the phone is rooted properly. Unfortunately, the only thing that doesn't work is my GPS. I tried many guides (and also a lot of apps), but the one that worked best (Mobileuncle) gave me a GPS signal that was so weak I couldn't even dream of getting my position right.
Google maps only knows which town I'm at (probably because of my WiFi). Anything I can do there?
Thanks for helping.
EPO Updater
This is the best solution that i know of for this issue:
EPO Updater v1.2.1 from dr-lex.
Hello,
I get a GPS fix within 10 seconds. But with Maps, however, the signal jumps back and forth. Also, the signal does not show exactly the location, or a few meters away. These problems are probably also known to the UMI users. Somehow I have read what of MTK tools, where this problem can be fixed. Can someone post a tutorial, or link?
Thx.
Hi, looking forward to fix the same issue... Any news?

Gday mate,
I was having similar issues with my GPS jumping to the street next to me whilst driving and getting itself all turned around. The other issue I had was bluetooth would not connecting to my car, so I tried a few things on this list: http://www.theandroidsoul.com/fix-nougat-bluetooth-issues/
Specifically what seemed to fix my bluetooth AND GPS was this: (I also set the passcode on the car to '0000')
"This is a really good fix, confirmed to work by many people. To reset your Bluetooth settings, fire up the Settings app, and locate and tap on Backup & reset option. Now, touch ‘Network settings reset’, and then ‘Reset settings’. Confirm this on next screen. Note: This will reset all your settings related to WiFi, Bluetooth and mobile data. Keep that in mind. If you need WiFi urgently, then better do this later on."
The above made my GPS a bit more stable. Since then I have updated the device to the latest beta: PLUS.V3.02_20170208_c239v55_kw_u3_no-DB and GPS is working perfect now. Link from bencebacsi on UMi Forum: http://www.mediafire.com/file/hh1069alx7v8i6i/PLUS.V3.02_20170208_c239v55_kw_u3_no-DB.rar
Best of luck mate!

It's not usable for this problem.
I tested Faster GPS after rooted, MTK tools, Engineering Mode, and another more tools and tricks, and nothing helped me with better gps signal on my UMI plus.
In enginneering mode I deleted data from hot, cold, warm and full gps start without A-GPS started, A set position from detected position, download new satellites positions, then start A-GPS and it was same how before. GPS signal on Mediatek chipset is bad.
Sometimes I have fixed 12 satellites, another time zero satellites. Gps signal jumping from zero to good in the car, or outdoor.
