Hello -
Sometimes, I try to use the internet on my phone, a Samsung G S2 (SGH-T989), and it times out (gives me a 400 Bad Request). If I go into Airplane Mode and then back out of it, it then works as expected, except that if I put it in my pocket for an hour, or leave it idle, it will usually require this procedure again if I want to use 4g. Obviously this is irritating.
I called T-Mobile for support, and they want me to call from another phone, which I can do, but not until I'm back home from a trip I'm currently on. I have a feeling they are going to want me to bring/send the phone in, which I have a problem with for two reasons:
1) The phone is rooted and using Juggernaut 5.0, which is a pain to un-root and bring in. (This is minor, though)
2) I believe they are going to give me a refurb phone, which doesn't seem reasonable, because I purchased it just over a month ago, but it's outside of the 14-day return period.
#2 is more suck than #1, but I will do it if I have to. It just doesn't seem like a hardware issue to me - the 4G works just fine as long as it hasn't timed out. The thing is, it started happening right away at the office when they activated the phone, and I've even installed a new ROM (several, actually, but for a different reason, I can only seem to get the Juggernaut one to work currently) to see if that helps, and alas, it does not.
So, I'm wondering if anyone could give me some tips that might help me fix this problem myself, if it is indeed a software issue, rather than having to wait for T-Mobile to find a solution.
Thanks!
I have two SGSII phones on T-Mobile. I just came from Sprint where I had a SGSII as well. I have had T-Mobile for 2.5 weeks and have traveled twice since then and both times were a distance of 800 miles or so. During this time I needed the GPS as expected and had countless problems.
The problems are very inconsistent and numerous to mention them all...
The generalization of it would be problems locking on to the Sats. In addition to that the GPS also has problems fully functioning when there is a Data loss. It seems to handle a loss of data differently then my Sprint SGSII did.
I am often having inaccurate locating, being off several hundred yards.
Sometimes it will lose the GPS signal altogether, and when I check the GPS app it shows 20-30 SATS visible and 0 connections etc.
With all this said again the Sprint version performs very differently, something is off. Also since I have two of these I was able to test better, and the results are almost identical. There were times that the performance was worse on one then the other as well.
Just to add, I have tried several different ROMS hoping the performance would be better with no luck. I also have tried the aGPS patch that is on here, however I believe that is more successful with the international SGSII and the ATT one.
I encourage anyone experiencing GPS issues with this phone to please post here. I also encourage any DEVS that read this or experience this issue to please check it out for us.
Thanks for taking the time out to read this or participate. Also when you post please include which color you have and roughly when you purchased the phone.
For me navigation is one of the most attractive features of a smartphone. So far my experience was very good with the T-mobile SGS SII. I am using stock firmware with removed bloatware, primarily CarrierIQ, social networks and Samsung media services.
I've found that T-mobile version can use Glonass satellites along with the US GPS giving it higher accuracy and faster lock.
Recently on my ocean trip I've used Navionics US east application in offline mode and it worked as fast and accurate as Google maps. That app is using preloaded maps without online data assistance.
In my experience Google maps worked in Europe as well as in the US.
This phone has drastically better GPS performance compare to the Samsung Vibrant.
It might be that success is dependent on a particular application because all of them do position data interpretation in its own way.
For clear comparison it might be useful to mention what apps were used for testing.
Glad I'm not the only one.
For whatever reason, the AGPS patch completely destroyed my GPS and its ability to lock to anything, so I had to hard wipe my phone after. Tried every single version the OP had in that thread.
As much as I love this phone, the HTC phones of last year had far better GPS.

The only time I EVER have GPS problems is when my phone is left on WiFi with the GPS off, or if my GPS icon doesn't start flashing when GPS is requested. Flicking GPS off then on fixes that.
If left on WiFi and GPS tries to locate me, it will never lock on.
For those that "dont have problems", how long does it take to lock and do you ever have issues where accuracy goes down for no reason?
Also if you have posted please post the color of the phone. As silly as it seems, I have heard that the white model has different issues. The only way I can think that would matter would be a batch manufacturing issue. Either way the info would help. Also a general timeframe of when you purchased the phone could help as well. Thanks!

Well that's hope for me. The Sprint one I just had was solid as I mentioned prior.
well my gps on stock had no problems, un juggs no problems, i was having problems on darkside with no locks at all, but yesterday i installed the agps patch on darkside rom and im now having locks pretty much instantly so my guess is that it might have something to do with kernel or build or something.
to be honest if your in stock i wouldnt flash the agps patch, i would only do it on a custom rom that is having gps issues.

Try going to accessory greeks and check out the wireless Bluetooth receiver they have in stock for 99.99$ it's NMEa, I have three globalsat bt-359 genuine and it was very cheap and it responds very slow on my s2 andI wind up missing turns, but it should work anywhere you get clear sky, except the Sahara and a few other treacherous Arizona and Nevada stress areas probably buying one of the ones on accessory greeks retail do a custom tailor job. Happy trails.

My phone is black if it can help you
In regards to how fast I can tell that it locks in 5 to 20 sec with accuracy up to 9 feet.
In my experience the best results I had with the stock T-mobile ROM.
T_mobile is also the carrier that makes use of Glonass navigation satellites, not sure that others do the same. Typically I can see more than 21 satellites of both systems.
I would suggest to look closely at the software running on your phone.
Samsung included test software allowing to check signal to noise ratio and locking speed of raw hardware. If you find SN better in the range 22-34 and reasonable lock time your phone is fine.
Try flashing this, it may help.

I have similar problems as you especially with inaccuracy and sudden loss of GPS signal In GPS Status I see, the error being as large as 150-200m in the beginning. It narrows down, gradually in a minute however its still is as large 15-30m. Sometimes its down to 3-4m from there. Sometimes it doesn't lock at all as it sees no satellite or sees them but unable to lock. It is very very unreliable as you have said.
I have Titanium version of t989 which I'm guessing is couple of months old. I got it from eBay recently. Also i'm not using any case at the moment as according to some people it limits it range.
For comparisons sake, I had HTC amaze short while back and it would lock down in 5-15secs at same place with error usually within 4-8m.
I tried aGPS patch but i don't see any improvements with it. Additionally it sometimes make the GPS act weird, like GPS status will show it locked on 1 satellite, if I open up google maps, my location had error of couple of 1000s miles, lol. I was being shown in CA (I'm in mass)
@For people having more issues with aGPS patch, no need to hard reset, it simply updates GPS.conf. You can restore your original gps.conf from my earlier post using root explorer. Its present in /systems/etc folder
First I thought it is GPS driver implementation problem with this phone but
could it be, in our phones the GPS antenna is damaged as it doesn't make any sense as most people have excellent gps performance ?
I purchased a black SGS T989 in March. I have zero GPS issues, usually lock in <5s to 4-8m. I find the spectrum of different experiences with GPS on this phone interesting, I use my phone as a daily driver (quite literally, it's my GPS too!).
Just sharing my experience, I am currently running the ICS Perfection Rom. And I was/am having GPS problems until today. I downloaded the app faster fix off of the play market and did a quick reboot>ran the app> then full restart. And now I get a pretty solid lock around 10-14 satellites.
Just sharing my 2cents. I think the problem has to do with the NTP. If that makes sense.

no issues on my black one, only really use GPS Status for ~2-5 min at a time , locks on to 10+ sats in ~10 sec max. While driving down highway mainly, if it makes a difference , using Darkside 2.3 and whatever kernel it came with
Guys I had similar issues with GPS until I narrowed it down by doing various experiments with different ROMs/ back to stock/ hardware etc. It turned out to be my CASE!!! I had bought this case with shiny metallic coating on the inside and it was causing the issue. With the case off I get a lock in less than 5 seconds...Hope this helps.
On AOKP M6, locks in a few seconds, accurate to between 10 to 20 meters, I've seen it as accurate to 6 meters!

I may be skewing from the main topic but hear me out. I owned an SII for about 5 months before switching to the Galaxy Nexus however still have two Tmo SGSIIs in the same household. When I had my SII I would in fact encounter the aforementioned GPS issues. They were completely sporadic which made the GPS feature highly unreliable. Spending some time with the GN I have not encountered any GPS issues, GPS locks within seconds and no loss of connection. I was curious as to why my SIIs GPS was very fickle so I did some simple, field tests if you will. They consisted of the placing of the phone in certain positions while driving for example. I found that with my SII, I had to constantly keep the phone in my hand or close to windows or the dashboard, otherwise the GPS connection would simply drop. The same if placed upside down, the accuracy radius increased dramatically ( distance-wise). However on the GN the signal remains strong in situations where the SII would lose GPS connection. To say that those affected by this issue have a hardware defect would be inconclusive but I do feel as though its not software defect.

I updated my unlocked uk handset to 4.1.2 the other week via kies and wiped the handset afterwards
Im getting slow down / stuttering regularly and cant work out why any ideas
Its now as smooth as 4.1.1. seemed to be and ive exactly the same apps
Any idea how to sort it out ?
Thanks

You're not alone - I actually just posted on this on another thread - as follows FYI;
I was expecting to find more people talking about issues with the 4.1.2 upgrade - does appear to be a minority (that I am unfortunately in)
Since upgrading, my (sim free) Note 2 has gone from being just about perfect in operation and behaviour to suffering;
- Daily episodes of freezing (often requiring a battery out to reset)
- 2 or 3 times a day it will randomly re-boot itself
- whilst typing on keyboard often suddenly goes very laggy
- battery life has *defnintely* worsened (probabbly by around 15% or so per days use - it does deep sleep though)
- calendar view/settings reset themselves every re-boot (annoying)
All the above annoy the cr4p out of me, as I am super picky with my phones/devices and I'm pretty dissappointed with this - given the phone was SO slick pre-update. I can't stand to have a buggy phone, so unless there's an update to cater for these issues very soon (.3?) it's S4 for me.
(I would roll back to .1 in a heartbeat, but looking at how to do it, it's tantamount to a rooting processs in it's 'complexity' - you guys may be adept at such things, but to me they just look like an uneccessary ball-ache - shame there can't be a kind of 'macro/apk/idiots program' that does it all for you! But there you go, I'll have to suffer for now and see which way to jump in a few weeks I guess).
My advice? DON'T upgrade to .2 - I can't see any discernable benefit in day to day use, but I can see a LOT of irritating downside.
Very pi55ed off
Glad its not just me, it's doing my head in
Can we not just back track to 4.1.1 via odin ?
Id do anything to go back to 4.1.1 as I can't cope with the daily lock ups and stuttering
Can anyone advise how to get back to 4.1.1 ?
Sent from my GT-N7100 using xda premium
Yes you can roll it back and the article I saw on how to do it did mention Odin - (I found a 'tutorial' on how to do that a couple of days ago). Thing is as I read on and on and on through it, it's just not something I want to touch (for now....) as it looks like there *may* be some potential risk.
Anything with 'odin' involved I tend to assume involves rooting and frankly looked too complex to me and beyond what I'm prepared to venture into - plus I really can't be bothered to root mine (partially for the same reason), as - given I can (and do) run a custom lancher, I just have no need.
I may have a rethink if nothing transpires in the form of a fix for this screw up....

well took my phone into my local Samsung repair centre and its now en route to Samsung as they tried 3 times to re flash (they say its deeper flash than via odin) and it failed so it looks like my motherboard has failed and needs a new motherboard which will of course generate a new imei also (pain as I have it registered for mobile phone insurance) ......
Im so glad I didn't try to repair myself !! my local repair centre is martin dawes in moss side Manchester superb set of chaps so much better than carphone warehouse where I thought id have to go
will hopefully have my phone back in a week fingers x
Blimey - that sounds pretty terminal - I guess if that is the case it has to be some sort of co-incidence surely? As opposed to being (entirely) attributable to the .2 upgrade.
I have no clue where my local Samsung specialist is, so I will struggle on in the meantime - however, the problems are getting steadily worse it seems....it's now re-booting itself about 5 or 6 times a day at random intervals!! :crying:

If your in the uk here is how to find out where your nearest location is
http://www.samsung.com/uk/support/location/supportServiceLocation.do?page=SERVICE.LOCATION
If you go on the Samsung website for the country your in , if your not in the uk go onto the Samsung website for the country your in and select support and they normally have a link to either ring them or locate your nearest service station
Good luck hopefully yours is just a software error - mine came as a complete shock that my motherboard was goosed
and it also means a new imei to
let us know how you go on
I was recently contacted by an old friend to help with an issue. He was a victim of privacy invasion on his S4, hidden instances of webcam and phone cameras, exporting of personal information, etc. Now he has come to me for help. I have looked at his logs and whatnots, but nothing really stands out. So, I am wondering if any of you have experienced the same problem? If yes, please provide me a complete list of all the apps you have installed on your device. Since I do not own an S4, it is hard for me to create the issue. The only answer is to get this community to pool together and get me the device (which would allow me to dev for the S4 and bring the greatness of the Lightning Zap! kernel), or for you guys that have experienced it, to help me find a common link.

Hey man! How goes it? I would love to have an S4 but it's just not in my budget right now...but at about 600 bucks (with no contract) who can afford it...lol
Although, I am up for my new every 2 upgrade... but it is for AT&T, and I'm not sure of the compatibility between the i9500, and the AT&T model (not sure of the exact model number).
As for the invasion of privacy issue, I'm trying to get more details on it. But I'm really thinking the malicious code started on his PC and drifted to his phone. And if it's the trojan I am thinking, then it attacks usb devices by making all the contents of that device hidden and appearing as if everything was deleted. Easy to get rid of, and easy to fix provided you have admin level access. Oh, and it was specifically made to attack Windows 7, but can leak out to other versions of Windows. Reason #1 to switch to Linux: Hackers HATE Windows and Bill Gates! lol

I mean, what were the indications? Like, what made your friend say "Man, I do believe my privacy is being invaded." You say nothing suspicious showed up in logs, the instances of camera and data exports, etc were all hidden... what gave the indication that it was happening?
A friend of mine recently had a very similar problem with his iPhone.
We quicly determined that the answer was that his phone was cloned using a scanner, which gave the bad guy power to hack into the device at the ESN level. Very hard to trace in any kind of logs, especially since the bad guy would have the ability to purge logs.
Your buddy might have someone similar. My friend was in Russian when this happened though, much less common in the US.

I asked him for more info and specifically what led him to believe this has happened. I am waiting for his reply. Here is th main snippet from his initial email:
I have been the victim of a very discreet but maddening invasion of privacy through my phone and also my PC and laptop computers via key logging, hidden instances of webcam and phone cameras, exporting of personal information, etc. I believe it to be a reoccurring problem via persistent data, local and cloud based storage, and corruption of my MBRs on most of my storage media. I know enough to be dangerous, but have yet to find any significant marker that points to faulty reflash process at least on my telephone.

He gave me some good logs, but I really don't have much to go on. With the statement about his MBR's, I think his computer was actually attacked and subsequently, his phone and possibly other usb devices have been compromised...
He has MBRs on most of his storage devices?
But I think he probably got Ratted on his computer, the guy controlling the computer saw he had an android phone and installed an android rat onto it when he plugged it in next.

Hi All,
Been a while on here - please be gentle!
I have spent the last 6 hours looking into updating my firmware from Android 10!
I have done this on previous phones, but my current phone is proving a little more difficult. For the life of me, I cannot find the correct ROM to flash. Whenever I come to something I think I have found I seem to have another issue.
I've tried using various tools (Bitfrost) but got errors.
I'm in the UK, and as far as I can tell, my phone is “XAA”, “USA unbranded (default)”. I'm not bothered about changing the region code (unless it can be done easily).
Details::
SW ver.: SAOMC_SM-N975U_OYN_XAA_PP_0001
XAA/XAA/ATT
I would really appreciate some help from you guys who are way more informed and cleverer than me!
Thanks guys and gals!
Simon
EDIT: I have found a bit more informstion - I think I would be ok using SM-N975U1 - is this correct?
That's the umlocked Snapdragon variant...
I have two N10+'s; N975U/Pie, N975U1/Android 10. I would stay on Android 10 unless you want cpu cycle sucking scoped storage in all its glory.
Personally I prefer Pie to 10, better functionality and usability. With 11 you lose even more and 12 is fubar... in my opinion.
The best way to trash a stock N10+ is to mess with its firmware.
Rule #1 if a OS is fulfilling its mission, let it be!
Upgrades/updates can and do break things.

Thanks for that info ... I actually have no beef with A10 other than one issue which I thought maybe a firmware issue.
My NFC works (I can transfer files between phones) however, I cannot use Google Pay, or Samsung Pay. I have read somewhere that this was a firmware issue, hence my desire to update.
I have tried literally everything to get it working (cleared cache, re-booted). NFC Tools confirms it works, but it just does nothing at the checkout.
If I can fix this issue, I'll be happier!

You're welcome. It may be doing that because big sister Google thinks you need to upgrade to be secure. May have to do with the region you're using it in. I don't know. I never use those features and don't want them on the phone. Don't want anything to back door in using that route.
Depends how hell bent you are on having those features. You could easily lose more than you gain by upgrading, worse it may not resolve the issue. The N10+ is a valuable and reliable work horse that will run for years... just as it is. If it's running well otherwise I would try to find the root cause of this issue or simply use other workarounds rather than the shotgun approach.
Yeah, I was wondering about being in the UK with a phone registered in the US. But NFC doesn't read my credit card either. Would have thought that would be an option.
I'm not necessarily a huge NFC user, but the other day I forgot my wallet at the petrol station after filling my car. If I'd have had my NFC working, I'd have been able to fire it up and avoid the embarrassment!
Anyway, thanks for your help!
Be glad you have the Snapdragon variant. They are very reliable and run well stock when optimized. If you do upgrade to 11 a rollback to 10 isn't possible if you upgrade the boot loader.
There's always at least a small risk when flashing firmware which can trash the device. The only time I would flash a N10+ is if the rom was corrupted which barring a hardware failure is a very rare SUE, single upset event.
I never tried mine to see if Pay works nor have I ever set a screen lock. The fingerprint scanner could be dead for all I know.
The flip side to that is never being locked out* of my own device, no data lose, and double tap on/off. The device is glued to me as physical security is the only real security. I realize this may seem extreme to some, but it works well in the real world.
*a SEU or partial hardware can lock you out of your device. Had no lock been set, no lockout would have occurred. Got locked out of a PC bios like that. The password -was- correct
That caused a mountain of trouble...
Thank you my friend. Wise words indeed and duly noted...
