GPS Position Question

Ok, bear with me.
When I had my HTC Touch Pro, I remember the gps program I used would sync to a number of different satellites and switch between them based on different times of the day, signal strengths, etc...
I know that I have read many people saying that their position on gps is off by about 50 to 100 yards most of the time, and nothing they do can correct this.
I know that with the current set of ROM's out there, I am wondering if some of using different satellites to connect to, which because of the position of those satellites may be causing this.
Does anyone know how to check which satellites any specific ROM uses when checking its position using the gps? If different ROM's (from different countries possibly) are using different settings, are they settings we can alter or change to correct this or make our locations more specific? I am relatively sure that the phone uses the network tower location as well as wifi signals to better set someones location on a map, but is there a way to better define where a specific phone is located?
(Note: I did a search or 12 and didn't find anything like this in this forum for the Hero, if you have something informative or relative to say, please be nice about it. Thanks for your input!)

i would think that the actual signal handling is done in the gps chip itself, the android os gets the position "told" from the chip once it is calculated, it also gets the signal strength told.
you can check the satellites and signal with free "gps check" from market.

The gps is based on geo-synchronous satellites. The accuracy is based on the algorithm used and the number of available satellites. There are offsets to reduce accuracy which are imposed to limit the military uses. There are sync points to known objects (towers) which allow refinement.
The time lag of the gps receiver radio could, if it were designed wrong , affect the accuracy, but not likely since most likely it stores the time difference to the clock, asynchronously. ( a guess)
You can get more accurate software (wasp) . My marine unit gets me to 10 meters. I can usually find stuff 35' away. lol
So to answer your question, I don't think roms unless they changed the kernel affect the accuracy.

I guess there is a chance that the ROM has set the GPS to look for certain satellites by default, thereby causing some confusion, but I'm not sure that is the issue because my GPSr seems to be pretty accurate unless I am navigating with Google Maps at high speeds. I was thinking maybe it was a speed issue of sorts.
That said, here are some grabs of the satellites I'm seeing using DamageControlv2.05 (and the GPS Test app):

Well, I agree with most of what you are saying, however, I think part of it is retrieving the signal from the gps chip, and I think part of it is the software on the phone is taking that information and combining it with the location information from triangulation with towers and its throwing off the location a little. Outside, with a clear sky, no buildings blocking me, and on the map (using satellite or map layers, I am still about 100 feet away from the map location. I know others have complained about it. I am just wondering if there is something in the ROM or software that might be causing it.

First, read up on aGPS, and how that works. Most people seem to think that it's a cheap, dumbed down, "pseudo-gps"... That's not true at all. aGPS is complete, fully capable GPS with extras that it can use to enhance both speed and accuracy.
A few of the things aGPS does to speed up the inital lock, though, can mean that the position is less than accurate for the first minute or two, until it acquires a full blown lock from the satellites.
When properly implemented, aGPS should be *better* than just regular GPS. There is room in there, however, for a programmer to screw up when coding an algorithm or two and actually throw things off. I'll admit that I would have thought that this would have all been handled on the GPS chip, but now that I think about it more, it's very possible that some of the logic is done by the software on the phone, and that could change between software versions.
Still, that's not the sort of code that rom devs are changing, so any inaccuracies caused by the software should be consistent between the various roms based on the same Android version....

[Q] GPS Issue... Actual problem or ar we being manipulated by Carriers?

I have a serious question here about the GPS issue. I am really starting to think that this GPS issue is somthing that is being manipulated by specific "carriers" so that if you are a big GPS user you will us the "carrier specific" GPS app like TeleNav.
The reason I wonder this is because as I read the threads I see tht people with "unbranded" phones do not seem to have as much GPS issues as those with branded ones.
As I read the new froyo posts I see that those who have upgraded through Kies "officially" (and there by are unbranded) are reporting that GPS is locking onto 7 - 8 satelites in under 30 seconds and get a PERFECT positioning while those who have used the reg. hack method (and there by are branded) still report that the GPS is horrible.
I may be way off here and dont mean to sound all "conspiracy theory" or anything but this is just my 2 cents. What do you think?

It's incredibly unlikely. All the SGS phones are branded in some way I believe, and all use the same hardware.
Some firmware's are simply broken GPS drivers. Remember, when Telstra in Aus shipped the Desire, they shipped broken GPS too (and HTC hasn't had similar complaints), but it does show that accidents happen.
Part of the difference in performance may simply be the load of apps running affecting CPU speed, affecting timing, or other random stuff.

Thanks for the reply here on this. I see what you are saying but if the issue is something related to the issues you mention above then why when a "real" navigatiin app is used (like the telenav app i have on my phone) does it lock on right away and is acurate almost to the penny? Google Maps and Google Navigation are WAY OFF by like 1500 meters... This still does not make sense to me...
Perhaps the issue is on Googles side?

My track and Google map really suck.
You can almost try any other program and they're always better.
The problem is that they do continue to next point they have calculated and if they se you have turn Away from your course they still use the point they calculated and move you to the point you are.
But you get waste data that's not true.
That's way you see so bad track on sgs when you upload them to Google map.
This is why many complain on the gps on sgs, but if they used a real gps program, and preferred an offline program, then they should se the gps do work.
Look at my stat when i drive my car.
In all other program its always spot on, but not with these program.
As you can se i almost have a perfect lock with a signal strength over 40 on four off hem.
So to say to me that sgs gps is broken and it is a hardware fault is to funny.

Ignore Damian. Listening to his GPS expertise actually makes you dumber, because it's always wrong (he is an anti-scientist). I think he mean "it seems I (Damian) does not understand how GPS works".
Every opinion does matter, but your unwillingness to actually learn about the topic you claim you are an expert on, has finally gotten to me, and I'm reporting you. You are hindering useful conversations, and whilst I accept disrespect can happen occasionally, we don't need jerks who are littering the forum with incorrect information.

Click to expand...

Ignore what DamianGTO said. Quicker locking might be perception for starters. Some Car nav apps start polling the GPS as they are booting (and some I've tried take a while to load). It might also be that some car navigation applications have been tweaked to select the optimum minimum accuracy dynamically. This wouldn't be possible in My Tracks, and if it does happen, it might not be in Google Navigation (this is simply speculation though). In an area where there are no other roads for 50m for instance, you only need an accuracy of 50m to place you on the road in an accurate enough place. When you look at the map it will seem mostly accuracy, but the GPS chip itself might be saying you are actually 24m to the side of the road.
No GPS can lock immediately, so something else must be going on. Even SiftStar 3's take 6 seconds or so to lock on hot start. It may also be that Google maps/mytrack are using more location sources, and some are causing issues. Remember, they all use the same API. When I tried Google maps though, I locked immediately too, probably because it was a warm/hot start (and had recently been used). Remember, GPS has 3 locking modes, hot, warm and cold start. More information is available on: http://www.gsmarena.com/glossary.php3?term=gps . All GPS receivers are affected by this, and all programs.

They are possibly using wireless networks/skyhook too as a location provider, whilst others might not (all android apps use the same location api to interact with the hardware actually). Turn it off in GPS settings, and I wouldn't expect this to be a problem.
Google might have reasons for using it if it's available in Google Maps at least. It might also be that some mobiles use mobile networks for tracking better than ours, and do use them in a way that provides much more accurate results. Summary of this though, is turn use wireless networks off!

For starters, SNR of 40 was probably taken in a field with very few trees around, on a good day without moving. But those values are possibly meaningless anyway. Plenty of us know for instance that the accuracy values can be incorrect.
Secondly, My tracks and other raw GPS tools will show the real track your GPS is producing. On sparse roads, clever algorithms can cover for poor GPS. Whilst commercial apps often do better, and Google nav might be a bit quick to put you on a side street, that's an algorithmic problem with the app. On dense roads or roads with forks, the GPS could be better. We also don't really know the refresh rate either, and that can cause issues.
I haven't really seen much proof the cause is because of your theory though. And I kind of wish you'd stop pretending as though all your guesses are fact.
Anyway, in summary, the GPS is ok for navigation, but isn't really fitness grade. Navigation apps allow a huge range of errors, and whilst I agree the offline apps seem to have better, in dense areas, many have encountered serious navigation issues, and at least in my case, it isn't accurate enough for jogging I feel.

Andrew. You still don't understand that sgs can have good gps.
Look at the picture i posted.
Its when i was moving and i do have almost a perfect lock and signal strength.
You still ignore this fact.
You also ignore that more and more people do report that mytrack and Google map don't work.
You also don't answer what op do ask.
You also write bad things about me time after time in every tread you can.
Try to understand all sgs phone is not the same.
Some are better some are worse.
Is true a use it for car navigation, but i could use it for other things to. The result would be the same.
My gps in the sgs do work very good.
If you understand how signal strength works then you should know that.
So stop telling lies about me.

I've seen your picture. Once again, it proves nothing (I can make a similar one). All you've proven is that you get good reception whilst standing still. Congrats. You haven't proven the location is accurate though, or proven anything else.
If it were just a case of "my tracks" and "google maps" (you mean nav), are dodgy, PROVE IT!
Damian's challenge
You are quick to tell everyone else they don't know what they are talking about. You CLAIM Mytracks and Google Maps is broken.
So now, to prove your point, grab a track recorder. It doesn't have to be mytracks, but it MUST be one which records tracks. Then, go for a half hour walk, at all times sticking to a footpath, or a consistant distance alongside the roads. Then post results. If the signal is waving around significantly, congratulations, your GPS isn't suitable for fitness like ours, but is still fine for driving. However, if the track remains relatively consistent, so we can identify what side of the road you are walking on, you've proven it's hardware.

You mean software at the end...
Anyway, I don't understand why people in this forum always link locking speed to gps accuracy. I am on jpm, I lock in less than 20 seconds all the time, but navigation with google maps/navigator is ****ty. Point is, if I look at gps data with gpd status app, I don't see any jumping of digital compass or latitude/longitude. This is puzzling. Is there a navigation program like navigon that I can try to test, for free or a reasonable price? I don't need another navigator, so I really don't care about spending 100 for navigon...

Sorry, my bad. But it doesn't really change much, because there is no way of knowing if the accuracy value being shown is correct in that picture unless it provides coordinates. In fact, there is no way of knowing if the SNR is valid at all. Hence why he needs to show tracks, based on raw data as the quality of those are mostly dependent on the quality of GPS.

You never listen and understand when people tell you that they have a gps that work.
You seems not to understand that signal strength is a key value to a good gps. You always want people post my track or other bad program.
You don't understand how a good gps works.
A good gps program knows when they get a faulty data and ignore that. Mytrack don't and keep logging it like true data. That why you se wierd tracks.
Also a good gps program use other sensors to make the position more correct.
I don't have any problem at all to navigate were ever i want to travel.
I also use the gps almost every.day.
So stop telling me that the gps don't work.

Seems like there is nothing wrong with the GPS when walking at least.
On my way to the food store:
http://maps.google.com/maps/ms?ie=U...23463503511037.000494650ddc3df0ebc99&t=h&z=16
on my way back:
http://maps.google.com/maps/ms?ie=U...64939,12.25894&spn=0.008962,0.019248&t=h&z=16
Both are pretty much accurate, just at some turns the turn has a bit too large radius.
Does this prove that the GPS works fine for walking?
I can't try it by car because I have none, but I tried with my bicycle, but there I have to agree that it isn't too accurate, yet it is still accurate so you could guess which road I am going on, but at turns it just goes off somewhere else.

Everyone... Thank You for your replies. Pwehaps my question was stupid or way off base but i diddnt mean for my topic to become an arguement. I just wanted to know why the google gps software doesnt seem to work.
I will try one item mentiined by andrew and turn off wireless network for gps use and see if that makes a difference.

You've said Maps is faulty and mytracks is.You keep coming up with detailed explanations of the algorithms, but I can't even imagine how you know them to be true, when you have clearly never recorded a raw track outside of mytracks before.So show us a raw track using something which isn't Mytracks, and then you can continue telling everyone else they are morons.
EVERYTIME I ask you to prove your claims you point to SNR values, present some amazing new research which you are unwilling to prove properly, and go into an endless cycle, get defensive, and ultimately, move onto the next thread whilst ever proving anything.
I simply ask you prove them once. You have NEVER done that.

*facepalm*. EXCEPT, when a program is using multiple location services if GPS drops out and resorts to Wireless, then the location might in some areas, be WAY off. Turning it off may help in situations where GPS isn't available.
For instance, whilst on the bus the other day, in Google maps I found my position was WAY off, because GPS wasn't working (the bus's coatings must have blocked the signals). Turned out after turning off Using wireless networks I had no location, but no location was as useful as a location which was clearly off by kilometers.
Wireless networks are useful in some cases, but if you are after precision, and don't want the possibility of seriously wrong positions being used as a fall-back, yes, turning it off can help in some applications. Maybe not all of them (because some might properly use GPS only), but some definitely (especially since Android developers can't assume the unit will have GPS, and apps like Google maps can benefit from location guessing).

I have record alot of Mytrack but they are always faulty.
That's way i have figure out how it works.
If you think Bout what i did write you should understand that's its true and that's way people have a big problem to get a good track.
This is not a problem only on sgs. Many phone has this.
Why i talk about signal strength is that's a very good way to show how good the gps is working and get the data.
OfCourse you need to lock at the signal strength with when you are standing still and moving.
If you block the antenna you will get low signal strength and get bad readings.
You still ignore this facts.
I have showed that i do have a sgs with great gps that has very good signal strength.
You still don't prove anything your self.

Ask them what problem was found, was it related to software or hardware?
Its mostly the settings which might need tweaking as per your location. I have noticed that 1st time gps locking takes time & you should have working data connection to assist its locking & after that the phone maintains a cache of your locations.
GPS dont work indoors so go out in open park 50mt away from the nearest buildings & switch on the gps & see if it locks or not. Indoor the phone uses cell tower to determinate your location but gps wont lock your location due to missing signals.
These are my settings.
menu>settings>Location & security>
check all with green check mark.
use wireless network
use gps satellites
use sensor aiding
Might help to lock, try these & report back.

5 mins = 7- 11 sats on a cold boot for me .

Did you tried a diffrent modem? Like JQ1 or something. Maybe that help.

I've tried several firmwares with different modems, all of them gave the above result outdoors, still after 10-15 mins waiting. The settings are the best touted around the web, also tried FasterFix... no luck.
I really suspect a HW failure or something with the antenna. The SNR value starts off at around 30-35 when the device senses the satellites, then slowly goes down to 14-18.

This thread should be used for specific feedback relating to KEXEC based ROMs (CM10/AOKP).
DOWNLOAD ROMS:
http://goo.im/devs/Hashcode/solana
I know many users don't have enough posts to add to the development thread.
RULES: Please read through the thread and make sure you aren't posting a duplicate issue or one that's been answered.
CURRENT NOTES (Gathered from feedback):
BUGS FIXED:
Better stability, everyone agrees very few random crash/lockups
KNOWN ISSUES:
Still considerable battery drain. This is due to several hardware components not sleeping correctly: CPU1, MPU and others. More work needed.
HW decoding is currently being revamped to use less memory (see YouTubeHD / netflix)
No camera function (at all). This will be a long-term fix with a new kernel driver for each camera sensor.
** MMS is a work-in-progress on *ALL* of our Jellybean ROMs. We are using a brand-new telephony-common .jar via Google "master" branch to solve our multiple radio / international switching issues. The downside is that Google hasn't decided how to handle MMS on this branch.
For now use GoSMS from the market.
DEVICES TESTED:
Verizon Droid 3 (XT862):
STOCK-RADIO:
*should* be mostly working (where noted) using the .zip files from me.
CHINESE-RADIO FOR US GSM:
Needs build.prop edits found here:
http://forum.xda-developers.com/showpost.php?p=33102553&postcount=422
China Telco XT883:
?? Might need specific patch to boot.
Canada XT860:
Can boot, but no 3g and warm cpu due to cycling services. Dev needed w/ a device to create a patch for full function.

Ok here goes:
Been running JB CM10 1103 for more than a full day.
- I'm using Strict memory settings from ROM toolbox and disabled HW overlays, and nova launcher from AOPK
Good:
- 0 crashes but 1 reboot
- Pretty fast, no really hangs. In fact it might be even faster than mavrom 4.5 for me
Bugs: (apart from the known like proximity sensor etc.)
- I've noticed that when sliding the keyboard out before unlocking the phone, the screen sometimes doesn't rotate to landscape properly. I have to unlock and close/open the keyboard to get it in landscape.
- I fixed the bug where it shows 1% battery in JB by charging to 100% in my stock ROM, and then wiping stats with battery calibration app.
It does return after reboot
Battery
- Used phone all day normally, in fact more than usual I think. It's not bad but I have a 1900mAh battery so should be better. Idle seems OK for some reason.

Long time user, first time poster
First and foremost, HASHCODE- You are amazing and so is your work. Thank you from the bottoms of my feet. (Heart isnt low enough for what you do.)
Now on to some actual feed back.
I am about to load up your 11-04 build, but my question is does WI-FI TETHER work and what do I need to use? I've tried the built in version and 3rd party apps to no avail. I have seen conflicting answers to others' request on the matter but haven't had solid answers that have worked. I have VERIZON X862. Thank you ahead of time for any other future advancements you will bring us.

just adding:
on hard keyboard alt keys do not work

Mms on vzw 862 not working either still...

aokp
been using aokp since i got ss3 and was able to test jb,cm10 and aokp. i stayed on aokp the screen sometimes goes out and is very dim also enough lag to crash the phone or i just have to wait hopefully not a repeat i could see how this would tie in with crashes. still enjoy it very much thank you so much hash

Hashcode: US GSM networks work perfectly on the XT883 radio using the build.prop I made based on your 10-18 CM10 Kexec (and works on latest as well.) Info and uploaded here; http://forum.xda-developers.com/showpost.php?p=33102553&postcount=422 I get HSPA 14.4Mbps (actual speeds around 5.5 on att in my area) and it shows an H instead of 3g Wish mavrom did that.
For others needing info, read the thread in dev section for unlocking for att/tmobile, I post my findings there. Including (awhile back) of getting somewhat dual mode on us vze/gsm without radio swap. I was able to receive sms, calls, and 3g data on vzw with xt883 radio, couldn't call out or send sms (could use google voice for sms and grooveip for calls over data though). Then swap to gsm mode for my sim.
Back on subject, built in tether works on xt883 gsm fine, mms, etc. Only issues are known issues, all radio aspects work.

Thank you so much for pointing this out. I'm not sure how I missed this. I have a TMO SIM in my D3 for testing and I haven't had a chance to get the phone working in quite a while.
Updating OP.

It works for me. Except the @ launching the e-mail app instead of writing @
Oh, and for me the lockscreen unlocker on CM10 is way out of place while in AOPK it's correct

general feedback
I am on Vodafone NZ running cm10 20121018
Simply unticked the 2 options under Settings, More...(default ones can not recall name now sorry) and after this the phone sorted out it's own APN settings and instantly started working on 3G / HSPA?.
Can honestly say I do not notice ANY battery use worse than stock ROM, seems the same to me? clocked CPU at 1008Mhz
+1 for reception on 3G in general, this is honestly better than it has ever been and I would know given on stock ROM unless standing by lounge window (with one eye closed, tippy toes and poking out tongue) it was not possible to get 3G, now it appears 80% of the time anywhere in the house it is on 3G !!
Occasional freeze, only times for me is when typing a text with on-screen keyboard and other times about to type an e-mail in K9 Mail.
Other than that running all round amazing in my opinion, motivated me to buy a replacement screen / digitizer !
Thanks for your work Hash, this phone would have long been ditched had it not been for your committment and skills.

just had my first random reboot. immediately my battery jumped ffrom 75 to 35. i havent swapped roms or been into ss3 since install.. gotta go back into gb now to charge to 100. btw as you can see altkeys dont work for me here but they do work in whatsapp

A +1 from the land of OZ as well. With 'alt telephony' off and world mode on, every thing I need seems to work i.e. I can make and receive phone calls and 3G/HSDPA data seems to work. The 1018 build wouldn't receive phone calls - phone.app would crash in response to an incoming call.
The phone worked out the APN for my carrier by itself once the right settings for mode were selected.
Power consumption doesn't seem that different from the old CM9 I was running or stock.
It would be nice to have a working camera, but thanks to SS3 I can swap to 'stock' if I find I need a camera and I don't have my DSLR handy.
I have had what appear to be random UI freezes where the phone wouldn't respond. But things were obviously working in the background as I got a new email notification while the UI was frozen in one instance.
Also a couple of instances where the UI didn't rotate to follow the orientation of the phone and after a while it appeared to unstick itself.
But since I can send/receive emails and make/receive phone calls, the ROM does what I need of it.
(I've not tried SMS or an MMS, SMS isn't something I use a lot with a phone that does email).

I saw a while back a statement about "sensors" not working properly so I assume what I'm posting is known, but GPS doesn't seem to work for me.

Phone app crash
Not sure if this is a known issue or not, and it only happened once, but when i was on a call and the other party disconnected unexpectedly, the phone app just crashed.

The gps works fine in 3rd party apps, but does not work in maps/navigation. Gps status & toolbox gets a fix quickly, shows accurate speed, etc like it should, but navigation sticks at searching for location, although the statusbar icon stops blinking and gets a fix. Maps just can't access it, permission issue?

gps was flaky for me when I first installed the rom..
I used gpsfix and now my gps works just fine..

Well, with a quick test, I can verify the problem is with maps. 3rd party nav app Sygic works as expected, fix in about 4 seconds for me. Maps will get course location from network, just not the gps module. I personally do not use network location.

Bluetooth access point doesn't work.
It pairs with my laptop but then doesn't install any drivers.
(but these things would be my last concern )

minimalist text?
Not sure about this one, but in 2 different launchers my minimalist text widgets don't ever actually load, they just say "loading", could be something stupid i'm doing, but this is the first trouble i've had with it.

I downloaded and am running the KEXEC-cm-10-20121103-UNOFFICIAL-solana on my D3 on Verizon and I noticed a small issue with Bluetooth. When I am in my car, and the device is paired up, I can't stream audio if my phone is plugged into the car mount or in car mode. However, if the phone is not in the mount or car mode it streams audio perfectly. Is there a known issue with dock audio in this build? Regardless of this small issue, I just wanted to say thanks to Hashcode for all of his awesome work supporting the D3! You ROCK sir!!!!

Mate S: GPS Issues?

GPS issues?
My phone's GPS keeps dropping for some reason. Places I had no problem with on my Nexus 5 suddenly become dead zones with the Mate S. Anyone else have similar issues? My phone was originally from China and I'm in the US if that makes a difference.

I have not had any issues, actually it is probably one of the best functioning GPS's I have had in a phone. It generally works fast and well I have just returned for a week's vacation where I used it everyday for walking around - no problems what so ever., and fast reception even using the phone with no data connection.

That does make a diff. Most China devices are hard coded to only connect to china based Sats and due to this they have trouble connecting to any sats that are not based out of china. Just one of the things you give up when buying china devices.

For me also the Mate S has the best GPS I ever had. Locks so fast and inside the building where I never had before GPS.

gps problem
After firmware update I do reset and a-gps stop working. The sattelites find slowly and works very bad

I use my Mate S from early December 2015.
On December 15th I upgraded the firmware to version B145.
I had no problems with the GPS until ... last week. Then (in Endomondo v 12.0.1), GPS signal dropouts began occur frequently.

I too have started to get blank spots with the sat nave complaining of no signal. Checking gps test shows plenty of sats. I have reset the agps and let it learn its own to see if its any better. Thus was spot on, not sure what has changed as the firmware is still the same at C433B114.

Yesterday, I upgraded my Mate S to Marshmallow (Beta - B303). The problem with the GPS still occurs but ... only the first few dozen minutes.
Then - for the next two and a half hour - everything returns to normal and GPS in Endomondo works fine.

I think, I found a solution to this problem.
When I switched battery mode to Normal (previously I used Smart mode), the GPS works normally all the time.

Hi!
Please contact to me on mail [email protected]. I have a question about gps. Thank you!.

Has anyone solved this issue? Would rooting my phone help? I'm in Canada and my GPS was working until last week and I didn't even do an update.

Same issue apparently with no reason or update at all....I think it s definitively a gps hardware issue, maybe due to overheating after hot times spent on the car cocpit....any news on thos topic???

Hi Guys, I has the same issue as I was not able to fix anything for 20mn. But then, searching on the net, I found GPS Test app that was fixing thing for Mate 8. So I installed it, I cleared my AGPS with it and then it updated everything and I could fix within 10s. So great. And sometime, even when I'm in a house.

Link please!

Found the apk but still hanging randomly...i ll try a factory reset...any othe hint?

I'm having The same problem. Today I'm going to try:
Power Mode: Normal
Prorect my exercise app: SportsTracker
Prorect GoogleMaps
Enable High Precision Location (GPS, mobile data and Wi-Fi, all activated, of course).
I'm sure the problem is a confluence of factors: Locked Screen, Power Saving Mode (Intelligent?) and unprotected apps, including GoogleMaps

Same problems here with GPS. Hope Huawei to fix these issues with an update. It has been a long time since the last update.
