aGPS vs. Hardware GPS - Mogul, XV6800 ROM Development

OK folks, I've loaded up the DCD Rom found here (version 3.3.4) and I now have a working GPS.
I noticed something, however, and that's that the GPS drains the battery fast. Reading some of the other forums, I've heard that Assisted GPS (one that uses the towers rather than the hardware in the phone) uses less battery power, but on the downside, is not as accurate.
Since I don't always need an accurate position, I was wondering if it's possible to switch between the two GPS versions.
Then it occurred to me - how does one know if I really even AM using the hardware GPS.
So.....
Here's some questions for some of you who know better than others....
1. How can we even tell if we are using the hardware GPS vs. the aGPS?
2. Is it possible to switch between the 2 without having to re-flash, or get into QPST?
I would think that this would be very desirable to switch between the 2.
.....and here's what I have....
Verizon XV6800
dcd Rom 3.3.4
Radio version 3.42.02
Thanks!

Gps does about no drain on the battery. Programs like garmin that run constantly using the gps drain the battery. Agps is great for fast accurate fixes. Standalone gps is great for accurate but slower fixes.
I would use agps if you have a data plan. The speed is the only difference. Just so you know agps pings the tower for your location and tells the phone which satellite to find first which is what makes it faster.

gps
seems to me I already know the Ans to this one, but I'll ask anyway.
I have a data block, that means no GPS for me with the 6800 Correct?
or is there a program I can load?

No, I think you should still be able to use "hardware only" mode.

yes you can use standalone gps. I do.

drewcam888 thanks for the help... but one last Question. is there a program needed that you would suggest?
*Edit* I had searched GPS and didn't find much for some reason, but now I do. I'll do my research sorry to ask, but if you have a suggestion I'll gladly take it.

I suggest quickgps.

GPS- is it the rom or radio that affects locks?

can we get this cleared up...
is our GPS connection affected by the ROM or the RADIO?
it seems that whenever im reading about a new rom that comes out people are always reporting their gps connection speeds. and whenever im reading about a new radio thats out, i see similar posts with people telling about their gps connection speeds.
-one or the other? both?
It is my understanding it is the radio

You cannot simply say it's just one of these things.
It is a culmination of things.
Radio... Registry/GPS Settings/GPSMode... cold/warm/hot start, etc...
There's a ton of factors.
But sometimes a new radio does *SEEM* to affect locktimes, but it's hard to prove.
"I cut/pasted this from my reply to another tread"
I'd say its near impossible to really get an idea of GPS lock times in relation to radio versions. The lock is dependent on so many factors. Weather conditions, relative satellite position, distance from your last lock position, EM interference, time interval from lock to lock, indoors / outdoors, the orientation of the antenna, how much of the horizon you are exposed to...
If you have a chance to use a dedicated GPS you will find that the lock times are variable even with a unit dedicated to finding the sats. Its the nature of the beast.

UK (and more specifically O2) radio performance

I got my O2 Serra last week, and was initially quite pleased with my battery life. Getting a GPS lock was a nightmare however, and so I upgraded the ROM - (PROven 1.09) and changed the radio to the 1.08.25.20 one as it had good reviews.
GPS was great, but damn did my battery life suffer. I thought I might have been in a dodgy reception area but was losing 10-12% per hour with no other usage! Switched 3G off and the power loss halved but was still too high. Tried the latest Xperia radio with the same results.
In the end I have dropped back to the stock radio 1.02.25.19 Took the phone off charge around 7 am, used the GPS for an hour and a half to get to work, have used the phone briefly and read emails (plus TOMTOM traffic data), and now six hours into the day the battery has dropped by 42% (This is all with 3G etc fully enabled). I consider this good as I am sure the GPS drains the power a lot.
My experience of thee radios seems to be at odds with most others in the radio thread, and many people do not specify country and carrier, making it hard to judge. Perhaps O2 have some specific network issues that mean that only certain radios will work well with it, and these are different to many other carriers.
Given that my experience on O2 (UK) seems rather different to the main thread and it is hard to isolate UK experiences there, I thought that anyone in UK could give a quick comment on the radio they are using, giving the radio, ROM and carrier they have.
Cheers.

il agree there, could do with more detail from ppl when posting about their UK radio performance....
I see you are using one of the radios I had problems with - how are you finding it?
Am currently on the O2 UK Network and heres my finding so far
Here are the best wo Radio ROMs I've used so far
Blackstone Radio 1.10.25.25
Currently using this:
Battery: Has been very very good though I don't think its been the best I've had
GSM/UTMS Radio: Has been very good I really can't tell whether this or the Polaris Radio has been the best, but I get EDGE at home where I never got this before. Also get UTMS on the Motor way much earlier than I usually get it during my travels.
GPS: Very quick cold boot, usually about 20sec for me. I've never really had the lag problem so can't comment much.
BT/WiFI: All seems good wifi doesn't disconnect as much as it usually did.
Quartz Radio 1.09.25.13
Currently using this:
Battery: Has been very very good though I think its given best battery life
GSM/UTMS Radio: Definitely one of the best if not the best.
GPS: Quick but not as quick as a lot of others no biggy 30sec from cold start!?
BT/WiFI: All seems good wifi doesn't disconnect as much as it usually did.
Don't think call quality was as good as the other radios.
Just my thoughts on what I've used.

Hi,
How did you upgrade to the Blackstone Radio 1.10.25.25?
This is what i have at the moment:
ROM.....: PROven ROM 1.11
Radio...: 1.02.25.28
SPL.....: 1.90 OliNex
I have the xda serra but i cant seem to get a lock onto any satalites.
It worked once - but thats all.
I want to try the blackstone radio to see if it helps.
I've downloaded the BS_Radio_1.10.25.25.nbh file but i dont know what to do with it.
I tried copying the file into a another file with RaphaelWrapper.exe but i get upgrade error when i gets to 100% - i then have to load the old radio back.
1. - are you security unlocked (different to CID or SIM unlocked)
If you don't know, then you aren't.
You must be to use non Raphael radios
If you are, then
2. Use the mirror site - I think it is properly packaged there.

I dont think i'm security unlocked - (havent done anything for it)
I did use the wiki site to get the radio.
How is your O2 XDA Serra - PROven 1.09 ROM, Radio 1.02.25.19 working with GPS? - does it lock onto any satalites? if it does i'll try out your settings first.
Works OK - havent had it long.
Best way for me - not always necessary tho is:
First make sure QuickGPS is fully up to date
then run Visual GPS wait for a few mionutes and see if it gets a lock
Then run TomTom
I stick the phone by the window five mins before leaving work and then hot start it in the car. Should be OK and will try again tonight.
Seriously though - you MUST be security unlocked to try Blackstone/Diamond radios etc.
Am gonna try out this mighty Blackstone radio everyone is going on about ... will report back tomorrow hopefully.
Hi all,
can i consider you´re experiences also working for me ?
i live in the Netherlands and my provider is Telfort ? O2?

Hi,
If you are having big problems getting a GPS fix, ensure that you have disabled the AGPS function in Start/Settings/System or use Advanced Config to disable it.
It should improve things a lot for getting an intial fix.

Hi WizP,
Great to see you over here in the Raphael forum.
I think we all suffer slightly from radio issues on the Raph..........
How does your compare with your signal on your Uni out of interest.
I have tried several radio stacks, but none as yet give me anywhere close to the signal strength and call clarity that I get from the Uni.
Cheers,
Beasty
I live in London, I am on O2 and use the 1.02.25.28. Having previously tried the .19 this one by far better with regards to signal strength and WiFi. I get one bar more than before. I have been using the GPS and it seems a little bit faster but nothing mind blowing and havent used it on a clear blue sky yet to see if this makes any difference. Will report back again and will compare this one to the blackstone over the weekend.

Battery life? The only real issue I have seen with any of the radios is battery life.
Tried the Blackstone radio last night - no particular issues- not sure 3g reception is as good but no other problems .
Will try the .28 radio next.

How is the GPS on the blackstone rom?
regards,
OK when outside or in car. No great change from the .19 radio I was using.
I have no problems navigating using TomTom apart from a bit of lag, but it is manageable and I am watching the other GPS thread for a solution - I have yet to try the GPSFix cab etc.
I've been meaning to start a thread like this for a while, as I think it's more helpful to discuss radio rom performance for individual locations. I'm using an XDA Serra on O2 UK, so far not very impressed with radio performance.
I've got the stock O2 UK ROM, and I've tried radio roms 1.02.25.19 (stock), 1.02.25.28, 1.08.25.20M1, and now on 1.09.25.14 (Blackstone). My main criteria is GSM (voice) performance, which is paramount to me, and I live in a poor signal area, so where I am talking about radio performance I am specifically referring to 2g GSM1800 voice.
Compared to all my other (much older) phones - Vox, tornado, Nokia 6100, the Raphael has much lower signal strengh - permanently shows 1-2 bars less on the display, and always much lower in 'Field Test' & GSMTestMode tools. I believe that the signal strength indicator on the vox and Raphael (both WM6) operate on the same scale, but I could be wrong, that's why I also check the RSSI figures.
All of the four radio's above have been very similar in low signal performance, regularly dropping calls and hunting for signal where my other phones hold 2 bars all day long and rarely drop calls.
This leads me to the conclusion that weak radio performance is a hardware flaw of the Raphael, rather than rough software - I'm sure HTC have got the radio drivers 99.5% perfect pretty much from the off - they have afterall managed it with past devices.
I am also using a GSM repeater in my house - let me explain this a little further. Without the repeater I can get usable signal in one upstairs room in my house. The repeater has a panel antenna pointing out of this window towards the nearest base station. I then have the amplifier h/w and repeater aerial (rubber duck antenna) in roughly in the centre of the building. This works very well with all my other phones - I can make & receive voice calls anywhere inside the building with at least 2 bars of signal using my vox. The Raph struggles with calls almost everywhere in the building, other than right next to the repeater antenna (where I get 3 bars on the Raph, and 4 on the vox).
The GSM repeater gives me a good tool to assess signal strength ability of the handsets relative to each other. What I have found it that when placed right up against the repeater antenna, the Raph shows a slightly higher RSSI than the vox (although the vox appears to limit the gain more intelligently, perhaps to counter too high a signal?). As the devices are moved away from the repeater, RSSI falls off far more rapidly on the Raph than the other devices, which is part of what leads me to believe the radio hardware is the problem.
My findings so far:
Stock O2 Radio .25.19 did seem slightly worse than the others,
.25.14 seems slightly better than .28 and .20M1, but we are talking very small differences and could be just placebo effect.
.25.14 might appear to be better as it doesn't look like it's 'searching' as much, but when I come to make a call, the two bars of signal strength mysteriously vanish, viewing RSSI in fieldtest seems validate that .25.14 continues to show two bars when in fact the signal has dropped substantially.
With all radios, I seem to find that I get better signal strength with the phone horizontal rather than vertical - this is unusual as the handset antenna is usually tuned to work better vertically, because thats generally the position it's in when you put it to your ear.
I've never, ever seen a 3g signal with my Raph, and I travelled all over the country with it at Christmas. Maybe I was never in a 3g area the whole time. I don't think telcos are putting up many more 3g masts, so it looks like we will be relying on 2g coverage for the foreseeable future.
Turning off HSDPA on the Raph certainly saves battery, and it appears to help the 2g GSM signal performance as well. As I live in Cornwall, the chances of me ever getting any advantage from a 3g signal are very slim!
I've never managed to get any GPS signal at all from the built in GPS. Not with any of the above radios, or even fiddling with Advanced Config, GPS Test, GPSID settings, HTC GPS Tool. I can't even find the built in GPS device on any com port. Works fine with my external B/T GPS box. Either my GPS h/w is faulty or the O2 Rom disables it. Frustrating, as everyone else seems to get it to work to some degree at least.
1.10.25.25 will probably be the next radio I try, although from what others have said it's not a huge leap forward in GSM performance.
Has anyone compared GSM radio performance to the Diamond, Touch HD, or Rose devices? As much as I love the features of the Raph, I use my phone for my business, and the most important feature is phone performance for me, everything else is secondary. At this rate I am going to have to go back to the vox for phone, and use the raph for everything else. But that means I will have to carry 2 devices where one should cope.
Sorry for the hideosuly long post, but I've got quite a lot to say about raph radio performance.
mike-b, I don't think your post was hideously long it was very informative, so thank you from a noob ; ) Just in case you haven't tried it, go to an area you know to have lots of satellites above you (if you see what I mean), run GPS Tool to see how many sats your pro is picking up and then just sit still and wait...and wait..... It took me two weeks of messing around to get my first lock. The out of the box settings work the best for me, plus patience followed by regular downloads of Quick GPS data.
To the original poster, I run an unbranded Touch Pro on O2 pay and go, on the standard ROM. I've tried the original .19 radio and .28 and I honestly can't tell the difference between the two with regard GSM/3G/HSDPA performance, and there was certainly no improvement in the AWFUL gps. (Does the radio even affect GPS? I've read so many conficting opinions on that front, LOL)
With regard to battery life, for me the biggest problem is that I live on the edge (no pun intended) of a GSM/Edge/HSDPA area, and for me switching between them that is what seems to kill my battery.
When I had the original O2 rom, getting a lock was a problem but possible, and once I had a lock it was fine.
Definately switch off AGPS.
There is some lag on the GPS with TomTom but its is easily usable - and hopefully the guys looking into it will completely solve it soon.
I only kept the original ROM on the phone for about a day.
At the start of the day, I run QGPS (if I remember this is not in the O2 ROM), get into my car, put the phone in the holder, start the engine, wait a minute or two at most, I get a lock and off I go.
The only odd thing I had was this morning where part way through my journey the GPS froze. not TomTom, just the GPS. it was very odd. it did not lose signal, just froze. closed TT, ran QGPS, restarted TomTom and away I went all fine though.
Am now running the .28 radio and will see how that goes over the next few days as I will be out of the office.
Just for the record, I get 3G/H most of the time, but live and work in SE London and NW Kent.
Have just started VisualGPS and put my phone by the window - so lets see what happens.
EDIT - and a lock within 60 seconds.

[Q] why is the GPS on the vibrant terrible?

is it a hardware issue? software problems?
I don't know how such a problem could persist for such a long amount of time, I really hope the Nexus S doesn't have this and I would likely shell out money for that (though the lack of HD video recording disturbs me)

Ever since JI6, the GPS has been able to "lock" in, but it gives terrible accuracy. It's accuracy that's important.
JK2 had choppy accuracy, JK6 made it slightly better. JL1 has been dead on for me, it even tracked my accuracy up to big bear (snow mountains in california). I went twice, once with JK2 or JK6 the first time, which sometimes listed me as off road during the trip, but when I went back with JL1, it went without a hitch.
I'm not familiar with these terms, but my accuracy has been fine, it's the speed which bugs me (takes as little as 10 seconds to as long as a whole minute before locking)
JK6? JK2? JL1? modem firmware?
Yep, modem firmware.

I agree, it is unnecessary and if this doesn't help consider an exchange.
Outstanding GPS Performance After Warranty Exchange!
I recently had to get a replacement phone from Tmobile due to a problem with the haptic feedback. I received a new (not refurbed) phone in original Samsung packaging with a mfg date of 10/20/10. The phone already had JI6 installed.
Since I've had good GPS performance on my previous Vibrant I was a little concernced about what might happen on an exchange. My concerns were definitely misplaced.
The new Vibrant's GPS locks up virtually instantly, faster than my old Vibrant ever did and with higher signal strength and more birds. I've used the navigation extensively and have yet to drop connection while navigating.
My first experience with the phone's GPS was by accident. We were shopping and I needed to get around a plugged freeway on surface streets I wasn't familiar with. I went into the Navigation app, spoke my destination and was INSTANTLY provided with my location and directions. Subsequent testing has also been 100%.
I've never seen GPS performance this fast and powerful with my previous Vibrant although it worked well enough to get me from point A to point B. The previous phone on occasion would take a minute or two to find my location.

These are typically rom build / version designators. The confusion comes from using these terms to refer to the individual components (kernel, baseband / modem, etc) that have been pulled from any given rom such as the modem. When the a proper context is present, it may not be too hard to tell how the terms are being used. That's not always the case though.

I realize now that Project Nero has JL1 already installed, so that's not it.
also, I have yet to see an answer to my question, what is the issue that causes the GPS to fail on these samsung vibrants?

JL1 was horrible for me. Constantly running on edge, and GPS sucked. Back to JK6 and everything is running great, back with strong 3G signal and GPS is acceptable (although accuracy is still off).

Samsung says the hardware is fine and that it is a software issue.
A few people believe it is quality control issues with the build of the vibrant (could be a loose connection and so forth)
so no one knows for sure, although most people do see changes depending on the software used, both for better and worse.
Not everyone seems to get the same results. (for some people, newer software fixes gps completely while for others it does nothing at all or makes things worse)
and then there are people that have had no real trouble from day one (they are rare, but there are some)
that's all anyone knows.
I think this question has been asked quite a few times already (there's even a few threads on this very page), you might check some of those threads for more info.

Probably multiple issues. Agps and status reporting were clearly busted originally, but that's fixed in later firmware. The accuracy issues on the other hand persist, for me anyway. Some people claim that they have no such problems, even with the exact same software, and if that's the case I can only assume sample variation in the hardware is to blame.

I have no such problems!!! in fact i've never had it lose reception. for me this phone has had bar far the fastest gps lock and the best gps! running stock rooted rom
Somethings not right. My gps locks in less than a second. Rock solid. Even inside a lot of times.
The t-mobile rep claimed that the glonass was already enabled, and its why im getting 1 second gps locks. Is that accurate? How can i tell? I know the chip supports it.
Mine too . Super fast. Fastest out of any phone yet.

Same here, the GPS on the Amaze has worked flawlessly for me every time I need it (which is pretty often since I'm always downtown and looking for something). Your Amaze might have a defective GPS component if it's always losing the signal or lock. I could be wrong, but I'm only guessing that that could be the issue since I've gotten superb GPS performance on every ROM I've flashed.
If you have task manager installed make sure you are not killing any system app that relates to gps functionality.

Xiaomi Redmi Note 2 gps test?

Hello everybody from Xda,
I'm looking for a new phone for my mother and I am really interested to know what the GPS is like. If the gps is any good I will join the Xiaomi army.
Why am I so interested in this?
Well my mother her navigation system just died and, I would like to install the tom tom app on her phone, I've got it currently on my oneplus one without internet and it's great. My mom will also have no data plan with her phone so google maps or anything isnt an option for her
So my question to you guys is, does anybody of you have had any ecperience with the gps.
Thanks in advance XDA,
Deameong
I am curious about the same thing. I use GPS without any Internet or even phone signal (normally on airplane mode to save battery). And I would like to know how reliable it is.
Attached a Screenshot, few Seconds (about 30) after switching GPS on. GPS receptions is really good, from my point of view.

Just recieved it now,
Using google map and waze, locking on me very fast,
Looks good and stable with great reception of the GPS...
Can you say how much time in seconds need to lock satellites?
Thank You
Thanks alot for the advice guys,
Going to order it tonight!
I've just come back from holiday and I used GPS extensively with the offline Co-pilot app. It worked almost flawlessly both in the car and when cycling. I can't begin to tell you how much better it is than older MTK eqiluipped phones. Lock times varied from four seconds to nearly a minute. One thing I noticed is that it was much faster to lock in Co-pilot when I was connected to the internet. Accuracy was great, though I never went into a big city with lots of high rise buildings.
GPS, Wifi and network signal 2-3 times better than on my Note 4.
GPS is sick, in my room after 2-3 sec.

Hello,
Runkeeper with someone tried, I hesitate to buy the premium just because of that?
(avec Runkeeper quelqu'un a essayé, j'hésite à acheter le Prime juste à cause de ça?)
I really want to know about the gps as well. I use the gps so much. Now I have the lg g3, I would like to know if this one is around the same as g3.
Thanks

Ill give uadvice gps locking depends onyour connection and area,i use gps in city with locking time vary from 10 -80 sec or more the signal was good but for gps signal its not good so it some time locks slower, this is qqualcomm 400 chipset ,newer version of mediatek might performs better and i have ever try gps with airplane mode one using gps test on aa mountain area and it lock 30 sec or less,the signal came out by it self with no connection so everything depend on your area and your xhipset ,newer chipset performs excellent on gps
I'd like to know more about how the GPS in this phone is faring for you because for me it's an endless horror story. Neither Google Maps nor Endomondo give even acceptable locations and tracking.
And the compass is so bad I wanna puke.
The phone is great in almost every other aspect, but GPS is fairly important for me and I'm starting to regret purchasing this phone. May it be fixed with better ROMs or is it a hardware fault?

I used it yesterday for half an hour in inner city traffic. The phone found the GPS signal in a few seconds with data connection, without it takes a minute or two. Navigation itself was worrisome. Went under a bridge and signal was lost for about 2 minutes. Then Google maps always thought I was going inside buildings or streets next to my actual route. Really weird.
Inside my room 2 - 3 seconds lock, the best gps on any of my past smartphones.

And what is that information good for since the moment you open Google Maps, Runtastic or something along those lines it doesn't have any accuracy and keeps jumping the whole time?
I'm sick of people sharing screenshots of GPS Test or GPS Status like they're proof of anything when what's really important is real life apps behavior.
This device GPS should be good..

I don't know what you're on about, but GPS Test uses the same API and sensor as any other app. I'm getting the same 5-7 second fix indoors from GPS Test and HERE Maps. Both don't jump around and show my correct position.

Well we use diagnostic tools to know accurately if something is wrong or not, nothing wrong with that. With GPS Status we can know how many sat signal we got, how strong, what is the margin of error, etc.
And i don't have any problem in real life apps and GPS status confirmed that fact.
If you want positive info or help don't start with a negative.

China ROM GPS problem
But with china stable rom, the map apps is using Baidu, and if your GPS location is not available, the device will report your network location (wifi/3G), which is in simplified chinese to your requesting apps, that sucks, however, I can't deny the hardware GPS here in RN2 is the best I ever used.
I tried GPS in the city. High accuracy, pretty fast lock and it worked just fine, no problems. Accuracy is usually 3-5m, 17 satellites in use on average. I'm not exactly sure what kind of problems you're facing. However, I can tell you this. A friend has Meizu M1 Note, the GPS was at first very good. But somehow at some point after updating, the accuracy's became horrible, 80m+ and it kept losing connection, IF it managed to establish one. It's most likely not faulty HW, but a misconfigured gps config.
