[NOT WORKING]Beidou and maybe GLONASS support on other Sony devices - Sony Cross-Device General

Inspired by @lukesan post i actually thought about getting support of Beidou to other devices. It also may enable GLONASS on your device, but my Z1 already does support it, so I've got no idea.
Will release new test versions for beidou GPS constellation support. Sit tight.

http://d-h.st/2W4
Currently tested only on the Z1 althought it SHOULD work on any Sony device with snapdragon 400+ SoC and android 4.4.4. Not sure whether it will work on custom roms, you tell me!
What do you get if you flash this?
Your aGPS module will use Chinese Beidou satellites to get faster and more precise location fix. Actually it will try to use GPS, GLONASS and Beidou, so that's three satellite constellations! :highfive:
Tested on:
Z1 4.4.4 Stock .108 firmware
Please report if it worked on your device. If it's not on the "tested" list then do make a backup first!

Olokos and others, a friendly reminder that if your GPS receiver has a really good lock it will only show the US sats. Quallcomm seems to only use Glonass and Beidou for low quality locks and faster fixes this is done to reduce the power and is actually a good thing.
A very good program to use is AndroiTS GPS (so no androidts gps) https://play.google.com/store/apps/details?id=com.androits.gps.test.free&hl=en
You can see the flag in front of the sat, so no guessing

Actually Qualcomm is using GLONASS and Beidou on many different SoC's. S801 AC included. It's just up to the OEMs which GPS constellations they will use.
I don't think they make it work only on a bad GPS receivers. Z3 actually uses Beidou.
Could you point me to any direction where it is proven that GPS using more satellites uses more power? I'm not really sure about that.

'To save power, the GLONASS receiver is only activated in problematic locations, such as in an urban environment with high rise buildings. Therefore, if you are in an open sky environment where there are enough GPS satellites available to calculate a good accuracy position, GLONASS will automatically be switched off temporarily to enhance the battery lifetime.'

Yup yup although Glonass is a bigger helper for the moment. I don't think the Beidou's are on, active, or fully deployed by now.
Well, more is always better!

I posted this as soon as I saw Beidou satellites in the GPS Test app. That is right after flashing this zip

LoL very nice, I wonder if it would work on older phones like the HTC HD2 or so since I remember there was talks about that qual-thing also been able to support Glonass. (even then)

Works in Xperia Z (C6606, flashed C6603 4.4.4 including baseband)

Since the GPS topic is on, before flashing this. my ZL 4.4.4 couldnt get lock on any sattelites and it keeps on searching. Can it be the receiver inside the phone got damaged?
after flashing this, still nothing have changed though.
Could someone please help me on it?

Take a look at that GPS news on the xda main portal. It will help you. If it doesn't then it's a hardware malfunction.

At this point I'm actually not sure whether it works at all. I need some people from asia to test this :/

But why Z1, Z2, Z3 use the same Izat Gen8B chip and still different? C'mon why QC don't start to enable it on 800?
NV? I find something about gpsOne on NV parameter...
And I think the map is right...Chinese gov has not been launch any more since 2012-10-25 as Compass-G6 is launch
And about testing on my Casio, it kill my GPS (no satellite signal, and gps toolbox crash :\ )

I don't think it's QC that didn't enable it but that was sony... At least that's what I think. I'll investigate further on this case then.

Yeah this also didnt work sadly. I guess it should be something wrong with hardware. But I brought it to sony center a lot and they jsut told me its fixed but then its not...
thank you anyway

No Beidou at all...

I'm sure that Taiwan is in its coverage...

Sooooo did ANYONE get the update today? Post your results please.

Well I doubt it seeing as sprint said they are having a issue getting it to google for distribution..
So that is their way of saying, we are sorry but no update and we have no ETA of when we will get it out. They are just pointing the finger at google, the same crap they always try to do.. Its never their fault, just everyone elses.
See here ... you can update it manually if you wish and there are screenshots / results being posted there already.
Tgrable, many people are seeing the OTA update now.
I think this update may have very well fixed a problem with the radio trying to find signal on Sprint towers vs roaming. I usually have to use roam control at home, but after a FULL stock restore, and installing this update; It just stays on roaming.
Too early to tell all what is fixed/if battery life is better. But hopefully it helps. I'll check 3G upload when I get in town later.
Though oddly, it seems to have killed clockwork.
If you get the same result; just re-do Clockwork via noobnl's method; works fine. Getting ready to test a custom kernel to make sure it didn't break anything.
(UPDATE)
Flashing the mixup kernel worked just fine. No problems I can see so far; so it looks like we are OK.
So guess what, to all the people who say upload doesn't matter.
My google maps took forever to load - i have traffic and satellite images enabled.
After this update, they are INSTANT. I tried it right before the update and they were their usual slow selves. NOW wherever I scroll it's instantly up.
Now sure you are saying "well they fixed the download too" however my download speeds haven't really increased. Just wanted to point out UPLOAD SPEED matters too!

I honestly think they just did some tweaks to the 3G radio drivers all together. Upload wouldn't affect what you are talking about, as that is ALL downloaded. Upload is only content coming FROM your phone pushed to the web.
But yeah, overall it seems ALOT better. I think there were more bugs in the 3G radio than we realized. Hopefully everyone gets a good experience.

Sure it would. Google Maps is a highly interactive app, constantly sending requests up to Google's map servers to retrieve map tiles for different areas and zoom levels, then displaying them.

It's funny how most people really don't understand that upload MATTERS.
A few days in a row here at my house I had 30mb down but my upload was only 128k - you wouldn't believe how horrible my basic browsing experience was.
Tech came, swapped modems, my upload went back to normal (5mb) and I could thankfully browse the web again!
While cruising google maps upload is absolutely important!!
Can actually get 1 bar of 4g at my house where I never could and gained a 3rd 3g bar in my room where I have always had 2 or less. More testing needed but seems alright

What? .
3G > Upload speeds increased. I'm getting up to 450kbps ^
Conversely, DL speeds seem to have decreased, but just a bit (though I haven't yet run enough tests to completely confirm this)
4G > After the updated, I've definitely seen an increase in DL speeds. I was maxing at around 7.9Mbps and now it's closer to 9Mbps. I am in Cali where they're still working on the network so this increase may not have been due to the update.
Major downer....I wasn't having all the GPS issues I've heard others having. My device would lock within 15 seconds and sometimes faster. Since doing the update I can't get a lock at all.

Ok, some weirdness. Downloaded GPS Test from AppBrain and all is well now. Don't know what changed, but I'm seeing 8 Satellites and locking on 7. My accuracy is 98.4 feet (30 meters in Google Maps). My SNR is in the high 20's. Seems to lock pretty quickly now (almost instantly) in Google Maps.
Where I'm at (I'm at work now as opposed to home where I was testing earlier) I'm getting close to 2Mbps on 3G down.
All in all, it WOULD appear that this update was good for my stock device.
kbps....
But yeah they are weak but with only one bar barely hanging on, but never had 4G spillover this strong before
3G on with new extra 3rd bar

What sucks is they no longer give out the air raves(name) for free and have to pay that puto ass fee to rent it every month.
Get this... they ended the free air raves if you had terrible signal about 3 weeks ago and I called about three days after it ended when they gave me the bad news.

Well I didn't have to go to complete stock, just stock kernel then just root it. I'll guess we need to wait for the custom kernels to incorporate this new patches stuff.

GPS show your good track/ signal strength.

In this tread i ONLY want people with GOOD gps post. Do NOT post any bad track or make any bad post about the gps. You have many others tread for this.
When you post do write were you record this, what firmware you are using, what manufacture date on the phone and what whether it was.
If you want to make a screenshot just press back button and hold it. Then press home button while you still holding the back button.
It don't work on every program.

Hello DamianGTO,
I've just upgraded my SGS to Froyo, and I've to say that the GPS signal has improved a lot.
Also, as in the screenshot you post, I'm unable to get a SNR above 40, which in fact is a bad thing, though :S

Let say you get 100 people posting a working GPS test and/or track. So what?
An incorrect track prove that there is a problem with the GPS. A correct track proves nothing. A correct GPS test even less.

Anyhow, this is one of the many tracks I got

Same rom used (JH2)
Added the use of TrackerBooster and that's about it.
Please respect this tread and stop spam it with nonsense.
If we can get as many as possible to post good track/ show the signal strength we maby se a pattern.
That pattern can help to solve the problem for people with sgs that had bad gps.
If you spam this tread you only show that you don't want a solution on the problem.
So start thinking on that before you even consider to ruin this tread.

And you consider that a good track! Have you even looked at it properly!! I like the bit where you run through someones house. You only take one sodding corner as well, and even thats not looking so cocky.
My god, straight, turn, straight and even thats crap. Try driving round by me, bends, corners, roundabouts, the things laughable at times. Not to mention it lags behind where I am between 5 and 20 seconds.
I may disagree with DamianGto many times, this thread is for different purposes. I've posted in another thread that the signal strength maybe related to whether or not your GPS works.
If you have 3 or 4 satellites with SnR close to 40 (or over 40 like DamianGto posted above), your GPS will work fine.
So, please post yours and stop spamming this thread with useless comments.
I don't know how to take screen cap. But my SGS GPS is just as crap as a lot others who complained. I have at most one satellite with SnR close to 40 or above. 2 or 3 are around or below 35. Most others are around or below 30.
Unless you ask people to post the serial number and/or manufacturing date of their phone then what pattern to you expect to see?
The only thing you will be able to say is that X people have been able to get a working GPS at least once. So what?
If you have 3 or 4 satellites with SnR close to 40 (or over 40 like DamianGto posted above), your GPS will work fine.

How do you know? Nobody posted SNR in function of time next to error distance in function of time and I bet no one will on this thread as there are no common tools for that.
There you go, I think thats a pretty good signal strength in anyones book, more than enough to lock and track me....and yet it does it so poorly, in fact it drops and relocks satellites every few seconds.
Correlation between signal strength and good gps = total fail
I already seen a pattern, but i want to confirm that's right.
I also want to know the reson behind it. Then maby we can find a cure. But if people don't respect the purpose of this tread and continue to post nonsense i just stop working on it. So its up to ALL of you.

The pictures you did post i don't considere to be a good one.
Signal strength is important and im more interesting in that. If you can post raw data( position and signal strength) on every point on a track it would be usefull.
I do working on this issue.
But i do it for others. Remember i do have a working gps so i don't have to do this. And if people continue to post junk in this tread i stop.

Thats me done, until you post a working track. Or is it that you can't and just love to stare at the long bars in GPS test and drool over them?
another ridiculous thread.
lock time and signal strength and number of satellites seen mean ABSOLUTELY NOTHING when it cant track you accurately.
my 3 year old nokia 95, while it did take a while to lock on, once it did (and i think it can only see 5 satellites at a time..) it not only tracked completely on the road the entire path, you could clearly see which side of the road you were on as well. every little detail. it was like 1-3 meter accuracy 100% of the time along a whole track.
ive seen nothing but garbage tracks from every single person posting them. i have a feeling that every single person who claims their galaxy s has a perfectly working gps just plain does not know what a working gps looks like.

My new Vibrant's GPS works better than my old one

It's no joke. Ignore the accuracy rating because it's just an estimate. Look at the SNR's between the two. It works much better in buildings, with Google Navigation, has no problem getting a lock, reported accuracy when driving is often 5-7 meters vs 10 then 40 then searching for GPS with the old phone. Never loses it's GPS lock, EVER and I've been testing it for a few days now. No big circles (stable lock)..

The replacement you got is JI6, correct?
Also if you leave it stationary, does the SNR jumps up and down or stays relatively stable?

It's no joke. Ignore the accuracy rating because it's just an estimate. Look at the SNR's between the two. It works much better in buildings, with Google Navigation, has no problem getting a lock, reported accuracy when driving is often 5-7 meters vs 10 then 40 then searching for GPS with the old phone. Never loses it's GPS lock, EVER and I've been testing it for a few days now. No big circles (stable lock)..
just fyi, when someone says their GPS works fine - they might be telling the truth

I see you're using 3G on the new one, and wifi on the old one. I get faster locks with wifi off. Can you try them both setup exactly the same? Not saying this accounts for the difference, but I like to see exact comparisons on things like this.
Thanks.
It's the same with or without WiFi on. It was tethered to the other phone. aGPS data was already downloaded. I've tested it both ways and there is no difference, the new phone reports higher SNR's

It's much more stable (obviously because of the increased SNR) but I don't know what the reasonable range is. Like I said below, it's cloudy so they should be unstable
Furthermore: off of WiFi for both like requested
It's cloudy today. The new Vibrant's GPS performed admirably when going under clouds while driving but accuracy did decrease. The old Vibrant is probably so bipolar because they are passing clouds. Maybe 2 minutes before I took that pic it had a better lock and as you can see, 4 minutes inbetween shots and the SNR has lowered and shifted on the new Vibrant but the older one completely lost it's (inaccurate) GPS lock.

You should be pretty much on the dot if your SNR is between 30 and 45, the higher the better obviously.
heygrl-
Just so I'm clear...are both of those phones set up identically, i.e., stock 2.1 JI6, etc.? No other differences in settings?
This is true, I traded my phone in because of gps, lag, freezing and crashing, etc...... Got a new phone and transferred all of my stuff to the new phone and the gps was dead on, no more lag and no more freezing, When I tried to use the bluetooth, no worky. tried everything, and so did tmobile, called in and ordered another one, it showed up and everything was great including the bluetooth, loaded in my apps and files and bluetooth quit working, went to tmobile store and they messed with it including a reset to stock and still no worky, pulled battery and it started working, reloaded my apps and files, no bluetooth again, pulled battery and it now works
I pulled the battery on the 1st phone twice and it made no difference????????
What can I say, I think the refurbished phones have been changed some how.....
The gps finds my location on a cold start in about 10 to 15 seconds and if I try it in navigator on a cold start it may take several minutes. on a hot start it takes about 5 seconds
The compass seems to work and when the car is stopped the arrow stays in one place on the map, but it may point in different directions.
If anyone has a phone that has lag issues and or the gps sucks, I would recomend that you do a warrenty trade in immediately, this sticks it to tmobile and samsung and should give you a phone that works

Maybe the reason your new one works better is because you haven't messed it up by tinkering with the GPS settings.
I've followed the GPS drama since the Vibrant came out, and remember reading your posts, you've messed around with the GPS settings a lot on your old phone.
Personally, I don't know who came up with all those fake GPS "fixes" for the Vibrant on this forum, they never worked, and just made GPS performance for me worse. I've had better luck on all stock settings. Seriously, why did the mods allow that thread to continue titled "GPS FIX" bogus, no fix at all.
Maybe going into your GPS settings and deleting data and tinkering with **** is not a good idea.
Enjoy your new phone.
I didn't touch the LBSTestMode settings on either phone. It's pointless stuff, it doesn't last/can make stuff worse for how ever long it lasts. Either way it doesn't really make a difference here. I recently lost everything on my old phone thanks to Eugene's FroYo and had to start fresh again. Even beforehand I haven't done anything in LBSTestMode. Changes in GPS software have to come from Samsung.

That's a problem, because even under these poor weather conditions (for GPS) getting down to 24FT/over my house on the map in my house is not a problem. Not any worse than the DROID X
The JI6 update OBVIOUSLY fixed the GPS lock and stable accuracy because it was listed on the bug fix list from Samsung and mine sure showed a very fast GPS lock via 3G even on a rainy cloudy day in California INSIDE the room upstairs a few feet away from the window and it worked at work place and a couple other spots even the phone was turned on after a full charge. And I love the Vibrant even more and I love GPS with the free nice looking voice guidance nav app from Google. And EVERYTHING that takes max cpu power and ram run smooth unlike other Android phones.

[REF]Signal/modem comparison

Figure I could start a signal/modem comparison thread and people could add to it if they wanted.
For my tests I used the following
Application Network Signal Info from the market (https://play.google.com/store/apps/details?id=de.android.telnet&hl=en)

Phone was sitting in same spot for all tests connected to same network and wifi router
Network being used was Rogers Wireless in Canada and I was located in Montreal
Rogers uses 850/1900 for 3G and 2G services. Same as Bell, Telus and ATT in North America
Phone is running latest ICS Wanam ROM based on XWLP7
Modems can be found in various places but the 2 locations I have gotten them from are

Speedtests where not performed since I was mainly testing for signal. You can add those results to your tests if you wish
For results measurements were taken every 2 min. Please note not all radios are supported by the app I mentioned and also I haven’t tested all of them so feel free to add your own results but please post he following
Location (country/city)
Provider
Frequencies they use if you know
Feel free to post your results but please do not post requesting someone test a radio for you. You can do it yourself so no need to have someone do the work for you. Post your results in here
Hey, that's great and all but... How do your results translate? Any impressions on these particular results?
**EDIT** Post taken from a random forum for information:
The difference between -72dB and -75dB won't be noticable because they are both well above the minimum threshold of somewhere around -100dB to -105dB for GSM. If you take the 3dB difference between -99dB and -102dB then it could mean the difference between dropping the call or not. Generally, you can say, for GSM:
-105 to -100 = Bad/drop call
-99 to -90 = Getting bad/signal may break up
-89 to -80 = OK/shouldn't have problems, but maybe
-79 to -65 = Good
Over -65 = Excellent
....but keep in mind, it's not the phones reception but it's uplink transmit power that limits the range of the phone.

When dealing with signal measurements I would rather display the numbers and not give impressions.
Overall I have never had any issues with reception or speeds on my device but I still like knowing what I am actually getting in terms of stats from one radio to another. From the info I got seems XXLPR s worst 3G performer on rogers vs the other 2 radios having at least 6db difference. Other then that wifi difference was marginal from one to another.
We shouldn't start comparing impressions and statistical data. I would prefer this thread simply be about hard numbers.
People can have their own impressions. Obviously my results may vary from everyone else but still a thread like this could come in handy for people asking about radios. Results will vary depending on traffic, location ,router etc

I personally hit alot of dead-zones with Fido/Rogers around my work area, which isn't really a justifiable test for modems... And anyways, I'm sure your results would be very similar to what I can pull.

Well if there are locations where you are on the limit of coverage doing these tests would be even more beneficial as radios will also perform differently based on reception available.
If your able to test please post what you can
it maybe be worth to also include battery drain for modems? i know this would be impractical to test out but atleast the testers could mention what they observe
WiFi performance has nothing directly to do with the baseband/modem...

For battery drain many more factors other then the radio that play a part such as display and applications so it may not be the best info to provide. Mainly want to focus on signal strength for network and wifi and maybe speeds also

I know the kernel plays a big part but the modem has to also have a part in the wifi
maybe im wrong
Nope...
Funny thing is I've tested between different modems (kj1, lpq, lpj, lps, and lpr) and got the same results for all (89db). Really is there any point to this, flash any modem and receive the same results.

Some of those wont work with the app you should get a pop up saying so bu LPS and LPR should give variations.
Even without moving the signal should change once in a while
I think that the most important thing to a modem is the voice quality. Unfortunatelly, for the voice quality we can give only impressions and not numbers for comparing modems.
Best regards.
How about this people should post the carrier, country and frequencies the carrier uses and the modem they think is best and why
Seems we can't all agree on what to specify but let's at least post modem info and carrier/country info
I just figured people need a reference thread of this kind
Can you re-run the test at another time, say between 2am and 5am, and in a different order, you might find very different results.
Due to frequent network fluctuations, your results will vary considerably depending on the current state of the network.
In order to get a real handle on the best modem, you have to many back to back tests, at different times of the day.
I have done much testing myself of modems, and as it shows in your results, there is not much discernible differences between the latest ICS modems, but it's interesting none the less.
BTW wifi has nothing to do with the modem/radio, but is related to the kernel.

If I recall correct this is caused by Samsungs software.
You should go to Settings > About > Status to see the actual signal reading.
Bare with me on the instructions as I'm doing this by degrading memory

yes, i checked the results there aswell. the one thing however since switching from kj1 (standard modem for vodafone in australia) to lpr is my battery life improved dramatically.
using betterbatterystat app the 'RILJ' now is under 10s wakelock, while kj1 had it in the 3-5min mark. both at about 10hours of usage.

That can't be true.. I had an issue with not being able to connect to my work's wireless network. It worked with the KI4 modem, but not with KH3... If I flashed between them, I could connect to the wi-fi network. Surely that indicates that the modem has some bearing on the wi-fi functionality? Also, I guess GPS is unaffected by different modems?

Is European Galileo GPS supported ?

Is European Galileo GPS supported on redmi note 7 ?
could anyone test this out and post screenshot. Use the GPSTest app by Dr. Sean Barbeau on play store, run it and see if Galileo (EU flag) GPS signals are received. Post the screenshot here.
for reference
https://www.gsa.europa.eu/newsroom/news/test-your-android-device-s-satellite-navigation-performance
Yes, it's supported and can be used as it did here.
thank you
I tested twice and phone seems to see those satellites as SOC supports it, but it cant connect to them. Is there a way we can enable them? Or is it still hardware thing?

It's a coverage thing...
It takes a minimum of four Galileo satellites to be visible in the local sky to fix a receiver’s position.

I stand corrected, You are right. I did more testing and it seems that Galileo satellites are used to obtain GPS location. Our SOC works a bit weird, it sees less satellites but it is faster and more precise that P10 GPS.
