GPS is a quality control problem

Hey guys,
I got in my 3rd "refurbished" Captivate last Friday and I have been collecting some data. For the record, I am using Cognition BETA5.5 FROYO on it without any lagfixes or modified GPS settings.
My first two Captivates -- the GPS sucked. I tried every fix in the book: Jupiter.xml fixes, Epic 4G fixes, LbsTestMode settings, different firmwares etc... some things helped a bit, but the GPS was still unreliable.
My 3rd Captivate's GPS works great from day 1. I've been testing it daily since I got it. I had a long trip to the New York Comic Con, which I used my 3rd Captivate to navigate. In areas that I previously had problems with, my new Captivate handles them with ease. I attached a screen shot of "My Tracks" on a turn that the GPS always overshot previously (now which works fine).
Anyway, I believe JH7 was the software fix for the GPS. The software problem was keeping locks from satellites <20dbHz and using >8 satellites. The rest of the problem is hardware due to poor quality control. This would also explain why so many people have so many different experiences. I say, if you want a reliable GPS in a Captivate, keep warranty swapping it until you get one that works.
/this also explains why some Captivates shutdown randomly, while others don't: poor quality control.

I disagree with this. I bought mine a few days before the JH7 update and didn't have a ton of time to play with the GPS. Using GPS test I was finding 8 satellites and locking onto ~6 of them in a minute or so. With the JH7 update I was finding and locking onto 11 satellites in 15 seconds or less consistently. My accuracy would stand at 16.4 feet (I don't think anyone has achieved better than this with this device). Starting this past Friday (10/8) however my phone won't lock at all. I'm only seeing 4 satellites and no matter how long I leave it, or what settings I touch there is no lock. This is a problem many people have. The GPS works for a while then suddenly stops. This to me suggests a software issue.

I think it is partially hardware related as well. My GPS on stock didn't work so well with the factory settings but worked perfectly with the supl.google.com. Every update since then up to Cognition 2.1.6 has worked perfectly every time for me. If this was a software or firmware issue we would all be having similar problems.

If someone proposed the theory that maybe supple.google.com isn't the best source I must have missed it. So I propose it. Spirent obviously is not, that's a test site.
I wonder if there is supple1.google.com supple2.google.com tzpst.supple.google.com etc.

I agree that Samsung has poor quality control problem, or lack there of from my past experience with various Samsung products. However, I believe the GPS issue is a bad hardware design in Samsung's part. Based on my own observation, it is the poor GPS antenna design that causes poor GPS signal reception. In compensation for this poor design, Samsung tries to boost the GPS chip amplification power which in turn causes interference from all the difference radio sources and bad S/N ratio. Since this is purely an analog signaling issue, different phones show different results and even the same phone could show different results in different environment. I particularly noticed that whenever I pass by those noise isolating walls around the highways I travel daily, my GPS starts to jump all over the place. This indicates to me that the GPS receiver is very suspectible to signal reflections from those walls, may it be cell tower signals or else.
The problem with warranty replacement is that it is really a crap shot. You typically get a refurbished phones unless AT&T runs out of refurbs. Guess where those refurbished phones come from: (1) returns due to GPS issue. (2) returns due to shutdown issue. Since neither issue can be resolved or easily identified (the later is not even acknowleged as a problem AFAIK by AT&T), Samsuung/AT&T will simply refurbish those phones and send out as warranty replacements.

That's BS. spirent is not the problem. The original theory has been proved wrong long time ago. Change to supl.google.com does not solve the problem. Period. And getting a lock is only 1/3 of the GPS trouble you get into.

1) I am using spirent (or whatever the stock SUPL server settings are) and my GPS is working great. The problem is not the SUPL server (although changing it might have helped some).
2) If it were purely a software / firmware issue, we would all be experiencing the same GPS problems, which we are not. In addition, I would see the same problems with my new Captivate (which is running the same software), which I am not.
3) I do not have poor S/N ratios on my phone. I get 25-40 (sometimes better) S/N ratios, which is a bit better than my wife's Aria. I did notice poor S/N ratios on my second phone (15-30), which had the worst GPS performance. If it was poor hardware design, we would all have the same poor S/N ratios (and performance), which we do not.
4) Yes, getting a warranty replacement is a crapshoot. But hey, your current phone sucks and your next refurbished phone might not. So, swap it out -- you might get lucky. Samsung owes you a good phone anyway.
The problem is really chaotic, and people cannot reproduce the same problems (and resolutions) across different devices. This can only explained by people not getting the same devices... some are just more broke than others. Poor quality control.
/personally, I'm sick of digging through the Captivate GPS problem.. now that I have one that works, I want to just enjoy my phone.

You are confusing digital circuitary with analog circuitary.
An analog hardware issue hardly will cause uniformly the same results. What you will see the S/N varies a lot between phones that's why some works, some doesn't. The antenna and satellite signal processing are still analog circuitary and prone to variations even with the same design. That's why SOME iPhone4s work just fine but others will drop calls when touched But no one is calling Apple lack of quality control.
Mine is 20 to 35 which is borderline.
The BroadCOM BCM 4751 is supposedly better at dealing with weak signals. I think Samsung is still experimenting different ways to get better locks in those marginal signal levels without causing the noise interference that in turn destroys the stable locks.

What is the general consensus of the % of owners actually having perceived GPS issues?

Someone please make a DIY on how to fix the damn thing myself... (hardware fix that is)

*Deep breath*
I know my 2cents really wont change this debate at all but ill go ahead and post my experiences with this issue K?
Cappy 1: Gps was just ok. it still worked but on navigation would try to "predict" where i was, jump off the roads and i would say on average i would be 20-50m off roof overhead and 10-20m if i put it directly on my dash where i couldnt see it.. This on average also took about 5 minutes to get a lock from standstill. Replaced for brick issue *incorrect flash being a newb*
cappy 2: Gps seemed to get worse everyday with this phone. mind you change the supl and jupiter tweaks seemed to help just a bit but honestly this one was just not usable. I could get a a lock in 5-10 seconds from a standstill and it would always be 10m accuracy.. so ok, it could help me know where i am immediatly but i cant see me standing in the woods going *deeerp where am i??* This was was replaced for random poweroff issue.
cappy 3: i literally just got this thing 2 hours ago picking up my mail so its fresh as can be guys.. jf6 stock right now. pulled my sim and battery into the phone at the mailbox and immediatly out of curiousity descided to test GPS. in no more than 20 seconds it got a lock of 50m..and then just a few seconds later im 5...5!!!!meters off. My eyes pop out of my head its in my hands at this time so i get ballsy and decide to put it in the lower tray in my car and take a drive. Wow...it just works now. It knew where i was and even told me and showed me a streetview of my destination before i got there...i should note this has NEVER happened i didnt even know it could/would do that :eek.
So my verdict is this. there are sofware tweaks to improve the quality and for some i dont doubt flashing firmware or applying changes has helped...BUT... overall this 3rd cappy is ...it just FEELS like the gps hardware is working right WITH the software. Things could always change with froyo and the the great devs here and if im proved wrong then wow count me impressed. Just dont hold your breath guys
EDIT: just to note exchanging your device is like playing the lottery. although these latest devices seem to have a higher success ratio im noticing. Ill also note i have NEVER exchanged instore but have always used mai to get my new cappy.

Based on the two comments here it sounds like I should try for a 3rd Captivate. Seems like 3rd times the charm. My 1st one GPS didn't work, I didn't run GPS Test or anything. Just know it never locked on me without the AGPS or whatever on. 2nd one same story. I have ran GPS Test on it and I'm lucky if I can get a view of 3 satellites outside in clear sky. It's usually 0 or 1. I've never had a satellite locked on.

If you have any questions, don't hesitate to ask.

I get this, too. The metal chassis feels premium. A little bit expensive though.

I too received mine last week.
overall this is a really good phone , nicely built , beautifull full hd screen , very fast.
only negative point , but i don't know if this come from my unit or if its general issue from this phone,
the WIFI and Bluetooth signal are weaker than my other phone ( Samsung Omnia 7 / Sony XPERIA U )
if i stand in my rooter room i got no problem , but if i go in my kitchen , i lose signal while the 2 other phone have very low but some signal still.
And about bluetooth , when i connect my audio headset , and put the phone in my pocket it sometimes disconnect when i turn my head in the opposite direction of my holster .
that never happended with my Omnia7.
Actually i can live w/o bluetooth but the WIFI signal at my job is low in my office as being far from rooter and i get trouble connecting
Can you guys test your WIFI and bluetooth signal ? against other smartphone ?

everything is just works fine , only we need custom roms

AFAIK every Mediatek phone with Android 4.2.2 suffers from that issue. Might be better with the upcoming 4.4 ... hopefully.

this phone runs android 4.3.9 but it might be the same . i hope it software or firmware related .
i contacted the shop but i doubt they will do anything as it does works but the signal is just a bit weak IMHO.
and i guess the chip is the same for bluetooth and wifi ... so same problem.
edit: made a picture but can't link it here due to being newbie

It definitely does NOT run on Android 4.3.9, an Android version like that does not exist!
As I said in my video, I am sure it runs on 4.2.x, probably 4.2.2
I also don't have any problems with Wifi at all, with MY setup, this phone has a very powerful wifi reception, a LOT better than most of the other phones I had so far

well i received a message from the shop this morning to send the device back.
guess i'll send it back as it seems my device is faulty.

As ColonelZap wrote - it is definitively Android 4.2.2 and not 4.3.9. There are currently no drivers from Mediatek for Android 4.3.x.
I have two other phones with a Mediatek cpu and both have the same BT issues like the K1, not with a headset (never tried) but with car connections (different cars verified). Establishing a connection is never an issue but any transmission is interrupted. Sometimes earlier sometimes later (1 min upto 5 min.)
But the WLAN connection of my K1 is pretty fine.So maybe your device has a hardware issue in addition.

yeah , i think that too , but what worries me is that the WIFI does works , just not so well , so i hope they don't send the same unit again...
well i will write down the serial number and IMEI and see
thanks for the feedback guys.

Just ordered this phone, i hopes everything runs well, waiting for another review or issues of the batteries, gps and etc?
@colonel zap can you share with us what you are doing with this phone until it's so powerful like that?
Thanx in advance :good:

terrible phone call quality
Hello I had 6 chinese MTK phones in the past 3 years. This one has the best build quality. Howeve it has ABSOLUTELY TERRIBLE voice/call quality, the other side can hardly understand me over all the humming, hissing, parts of words missing. So far I have not been able to complete a single phone call without the óther person saying "I can hardly understand you and what is all the noise and humming" This occurs in areas with very strong signal and gets even worse with weaker signal. It is impossible to make the phone call with less than 4 signal bars out of 5.
So far terrible experience at this price.

GPS locks fast and has strong reception - NO GLONAS SUPPORT (or at least during the testing I did not receive a single GLONASS sattelite) contrary to what is sometimes mentioned on certain chinese sites.
With 1-2 phone calls, hour of wifi and hour od GPS battery has about 40% at the end of the day.

Voice recorder as well as VOIP (Skype test service). Standard and OK sound quality.
Only occurs during phone calls. I have not yet had one without the person saying he/she can't hear me well or at all...

This is clearly related to the HW/FW of this one phone. It occured right out-of-box during first call and persisted ever since. It is not related to the GSM signal, location, provider (tested 2 different providers), contact I am calling.... Second phone I have in identical situation work jsut OK.
Not saying this affects all units, just sayng to be careful when buying.
Support from Kingzone is ZERO (sent 3 requests for advice and/or firmware file to try reflash)
If someone finds or gathers stock ROM let me know.

Does anybody in the USA have this phone? If so, what service are you using it on and what kind of data speeds are you seeing?

Should I buy it?

Hello, I need a new phone and I'm looking at the Nokia 3 because it has an e-compass and gyroscope, sensors that are a must for me.
Sadly most brands are leaving e-compass behind. So I got really exited when I saw that all nokias have it.
So far the only thing that keeps me from buying it are the bugs I read about the phone in this forum and others: screen that doesn't turn on, battery drains, charging that stops at 80%, phone getting slow/choppy, phone that hangs after using the camera.
So I need to ask you this... how serious are those bugs? do you believe they're gonna fix them or they are not doing anything to improve it? is it worth it?
Thanks.

Personally I haven't experienced any of those bugs, the only thing that once happened to me is that once the phone ran down and refused to charge or come on for a while. That said, I'm not sure other phones don't sometimes have similar or worse issues.
Might I ask, why do you need a phone with a compass sensor? Can't you just get a camera app from the play store, or wouldn't such an app work without the sensor?
Anyway bottom line is, the choice is up to you. I believe getting a phone without issues is sometimes a hit and miss situation. Ultimately you'll have to make the decision for yourself. I'm not really sure I can advise you on that. I got my Nokia 3 because I'd always liked the Nokia brand (but couldn't stand the WP os) so this was my way of declaring solidarity with Android on Nokia.
My biggest issue with the phone is the lack of backlight on the navigation buttons, which can be inconvenient in dark places. If that is not a deal breaker for you, you can go ahead and get it, but I'd recommend searching for info on people who have used the compass sensor first

Hi there !
First,I want to say Nokia 3 phone is for me a very good choice :
-have a clean pure android OS without bloats(thats why I am not sure it is a wise choice to root it or unlock boot)
-is a very fast phone if you disable apps you dont need(faster that a rooted debloated Xperia)
-I use MX or FV5 camera for taking very nice photos (at 8Mpx)
-Charging never stops if you know that Nokia 3 have a new protection system for battery-if phone is on charger and you use it a lot on 4g internet the temperature of battery is increasing over normal and automatically is trigged the protection suspending the charge until temperature drop to normal.
So is not a bug,is an enhancement for better battery life.
-If you search the guys who are over complaining you will see they work for competitors of Nokia.Dont forget is a tough competition and there are a lot of high end phones who are not on Oreo update program.Nokia until now keept their promise to deliver monthly updates and upgrades .
Also suspicious is the fact that MTK had double time to deliver drivers but is still delaying.
If you want the best budget phone Nokia 3 is by far the best choice !
All the best !

Hi, I'm using this phone about 2 months, and i had no bugs so far. I didn't tested compass so i can't really tell you about that function. I think that Nokia will fix those "bugs" that other users experienced because they release OTA updates often so you can be sure that you are on latest version. Design of this phone is nice, my friends like it too. Battery life is great for me, it lasts whole day without charging. Sound quality of speakers are ok, i would say average, sound quality through headphones is behind average, but that's my opinion. Customization of this phone is so far good. We have unlocked bootloader, TWRP, SuperSU root and Xposed. I hope that Nokia 3 can have some good Custom ROM. Performance in games are good. I play GTA:SA, Asphalt 8 without bugs in medium settings. Multitasking is ok, i can have 5 apps in background and no apps will be restarted.
I recommend you this phone, i think that it won't disappoint you.

Thanks for your replies!

I use a few astronomy apps regulary, those need e-compass/magnetometer to work. Also I'm a mapper and use a lot the GPS, GPS without compass is only half as useful. Being able to register where you were facing while taking a shot or registering a note is very useful in mapping, astronomy, hiking, etc.

My advice is to buy TA-1032 variant which is European variant and have dual-sim because it have twrp and stock rom in case you bricked your phone.
Other variants are ok too, but only TA-1032 have twrp and stock rom at this moment. I hope that twrp and stock ROMs will be available for all variants.

I'm from argentina so I don't know wich variant i'm gonna find here... I know it is dual sim, but that's all i know about the nokia 3 they are selling here, EDIT: appearently the most common variant here is the TA-1028, very few sellers has it at this time that aren't even official stores and it's not that cheap, they are selling it here for USD 200-270. That's why i'm worried too because probably I can't get any local support.

TA-1028 is single sim, TA-1038 will probably be the dual sim most common. I don't know if Amazon ships to Argentina, if they do and it doesn't cost too much, I think you can get the TA-1032 model there

sellers says it has dual sim :/
Sadly I'm not willing to buy it outside my country because there are high chances that the postal office steal the package when it enters the country. Also import taxes adds up to 50-60% the price, so the risk is worthless. Easily I prefer to pay those USD 200-270 and be 100% sure I'm getting the phone. After all these troubles I need a really trustworthy phone.

I can't stand my Pixel 3 anymore!

Hey everyone, I love my Pixel 3 except when it comes to the main thing a phone does, make calls!
The call quality is terrible. I know it's an issue many of us face from day 1, I need to constantly hangup and call people back. Now that I work from home and have call meetings non-stop, it is very apparent how bad the calls are. It is not a carrier issue, I have 4 other people on my plan and they are fine (no PIXEL users). This also happens when I'm using VOIP programs like Slack, Jabber, etc.
So I need to change. I know Pixel 4 is not a "great" upgrade to the Pixel 3 and hate to spend money on this "upgrade" but I might have too. Has anyone switched from Pixel 3 to Pixel 4? What are your thoughts?
How is the call quality?
Should I be looking for a completely different line of phones?
My phone needs to be rooted, run Viper4Android, and make calls.

Sorry to hear about your problems.
On my pixel 3 I don't have issues with calls, and reception is ok. It is not the best though, I had slightly better reception with other devices where there was a very weak signal (p20 for example).
Maybe the warranty could help if you.

I had strange issues before, mostly with bluetooth. I ran a 'network reset' and all has been perfect since. You will lose your BT pairings and WiFi networks though. Worth a try.

A few ideas to try:
Are you using a case? Some cases block microphones, which screw up call quality.
Turn off wi-fi calling (this was a major quality issue from my office until I turned it off).
Try a factory re-set, and re-pair things one at a time, trying calls in between.
We have a Pixel 3, 3a, and 4 in our house, none with any call quality issues. All on a T-mobile family plan.

Hi all.
No new post for a long Time.
Dos that mean that everyone sees the problem solved ?

This is the right thread for this issue: https://forum.xda-developers.com/pixel-3/review/call-quality-t3842383/page3#post83369547
But I think everyone will upgrade to the Pixel 4a or 5 now!

thinking of buying the poco x3 nfc, need advice!

i read here and elsewhere about some issues with this device, but i can't tell for sure if its common or just certain people who were unfortunate.. i have a few questions and i hope you guys could help..
1- is there a common issue with wifi and/or cellular(LTE, 4G, 3G) connectivity in this device, such as dropped calls, dropped signal, wifi misbehaving ?
2- is there a common issue regarding the stereo speakers? (some say people around could hear the person you're talking to on the phone, others say the phone vibrates when playing music!)..
3- is it possible to set the display refresh to say 60hz from settings, or does it change automatically and can't be controlled by the user?
4- are there any common issues with custom roms, for example custom roms for the note 8 pro all have issues with automatic brightness and maybe a few more things!!
5- is there anything else i should know or worry about regarding this model?
hope you guys could help. thank you.

This phone is the most bang for your buck imo, but nothing is perfect, so to answer your questions:
Signal strength in this phone is absolutely great, especially the 4G+/LTE+ mode (if your carrier supports it). If i were to to compare Poco x3 to high end devices, I would compare it to a Samsung Note 9 or in the similar generation/production year. Some Custom ROMs have issues with 5GHz wifi reception, but on most of them and stock MIUI you will find no issues.
After MIUI 12.0.4.0 (currently 12.0.7.0 is latest) the speaker problem was resolved. It mostly was due to the fact that calles were handled in stereo mode instead of mono and the treble was too high, but It was noticed quickly and dealt with. Music will still rumble a bit in highest volume, although it gives the bass a better boost (people here have different opinions on this issue).
If you plan to use the phone at stock MIUI, you will get two refresh rate options: 60Hz and 120Hz, both of which are dynamically adjusted to the content you are on. For example youtube will scale down to 30Hz when watching a video regardless of which option you chose. Custom ROMs (all of them) have this feature/annoyance called displayfeature hal removed and have added a 90Hz mode as well. So a stock experience isn't advised.
Nothing notable comes to mind. Ok maybe Camera is slightly an issue, but Gcam is getting better everyday where it's almost the same as stock cam (if not better). If you divide different xda phone forums into alpha, beta and stable, then our phone has already transitioned from beta to stable status. You have missed the "beta" phase by a few months now.
Like all Xiaomi devices, EDL mode is locked. Meaning a hard brick is costly to fix/repair. If you never flashed a phone shipped with android 10 before (most people haven't), then read all instructions very carefully, especially recovery threads. Magisk CTS sometimes doesn't pass, but that issue isn't really exclusive to this device.
I have bought two devices. One early in September, which has no issues. The other I had to return recently due to QC issues, as it only had 85% battery capacity (from official seller), so my advice would be to check everything including sensors and battery. If everything looks ok, then you're all set.
