Please forgive me if this has already been asked, I tried searching several different ways for this and so far have had no results. This is also a two part question and mini-rant/background info into the issues I've been having with this phone.
So first off I'm wondering if any one happens to know how to access (or if it exists/enabled) the field test mode. The code for the Samsung SGH-i607, *#0011# brings up the test mode but only info you can get is the email and phone # for, my best guess, a Samsung dev. I know I can get the signal level from Status but I was hoping for some more info like SNR and such.
Now for the second question and mini-rant;
I'm not new to the cellular game or Android, in fact I just switched to Sprint from T-mobile (had the G1) because Sprints service is by far superior to T-mobiles out here. Yet this phone makes it quite the contrary, reception fluctuates wildly and even drops totally no matter what I do or where I am and this kills the battery with in a few hours of a full charge. Heck even Sprint's customer care hung up on me twice because they couldn't hear me...
I really want to believe this can be solved with a radio update or new ROM because I love this phone but the DI07 update hasn't made a difference as far as I can tell.
Before I return it and swap it out for a new one or possibly an Evo 4G I figured I might as well ask to see if any one has any advanced tricks/hacks/advice I can try before I do.
Thanks for taking the time to read this and if this is in the wrong forum, duplicate, or what not let me know and I'll remove it.

Each time I flash new ROM, I go test GPS performance with GPS Test to see whether something changed.
What I'm interested in is primarily lock on speed, and also how solid the lock to satellites is, but that's secondary. (since froyo, the locks seem pretty solid, no more sudden drops like in eclair)
What I noticed is that even with same firmware this varies quite a lot, even when I try to make the test conditions vary as little as possible (I always test it from the same spot and hold it the same way to ensure similar signal propagation. I can't control the weather, but as it's winter, it usually overcast).
So my question is, do you find you lock on speed varies a lot with same firmware and in same conditions?
Mine can vary from a few seconds (rarely) to losing the patience after few minutes of waiting for the lock! (more often)
Is this normal or am I having some weird issues?
Because if this kind of huge variation is normal, then all my testing is pointless!
Same thing here, but used to me more "consistent" with original rom (2.1 from Bell canada, can't remember wich one). Now on jl2 it takes longer to get a fix and weather seems to impact more.
same problem...
gps works extremely unconsistant.
me and my girlfriend have same phone with same firmware and 99% same apps installed. if we put the phones next to each other the gps signal is sometimes the same somethimes really different. we tried to find out how this could be but didnt find any difference. some days ago i turned my gps on as we were at the city together and it took really long to get the location. and then looke dat google latitude and holy **** my girlfriend got the cirrect position there even without taking it out the pocket and her gps was turned off lol. thats a bit scary sometimes.
now i installed gps tracker booster to stay at the same location if im indoor. otherwise it jumps from one location to another all the times and latitude says ive driven 4000km in a day just because i was at home and walked from fridge to the toilet...
I wonder if it has anything to do with hardware antenna issues. There was a thread here somewhere. It might be, and yet it might not be. I'd like to be able to check if I have this hardware issue before risking my phone and surely voding the warranty.
It does seem to be somewhat software dependent, but that isn't enough. Inconsistency proves nothing
I could also swear it's getting worse with the time. In 2.1 I used to be able to get a lock in half a minute or so in the worst case (even if it wasn't solid). In 2.2 it was better but in 2.2.1 versions it was all over the place. Usually amazing just after installing the ROM, but then going downhill. So maybe it's just worsening with time or oscillating with ROMs. I'd need days of flashing and testing to get it sorted out - possibly.
Total confusion... In the end I'll just buy a dedicated GPS with a big antenna. Exactly what I wanted to avoid by getting the Galaxy.
Well, i did a lot of testing with my Galaxy S.
The only conclusion i got is that different roms impact the time the Gps takes to aquire lock.
I also concluded that is due to GPS hardware keeps losing the sinal makes you apear in places which in reality you're not or showing that you are going across a road when you are stopped.
In this case A-GPS diminuishes your acurracy.

I got slow fixes with JL2 too. But I am now testing "MS based" which improves lock time a lot (less than 20 seconds). I need more testing to make sure that my device is still accurate however.

Exact issue here... Lately I thought that I have some kind of bad habits due to installing new roms. But now i see, that I'm not the only one with this.

I had a "new" issue one time where it got all over the place so I deleted the data and redownloaded it (with GPS Status) and it fixed it. Might be that it keeps old data instead of refreshing it.
But it's not related to the time to fix
My life sucks right now, I have a big ass workload and everything I touch either melts or breaks. My HTC Desire had full signal strength in the same room using the stock ROM with any radios released but when using a custom ROM with any radios released (The same radios that the stock ROM used) or radios recommended by release - my wifi signal is constantly at 0/1 bar and it drops so damn much. It dropped twice whilst ontop of the router.
My laptop, Nokia N95, Nokia N97 and iPod has full bars without any problems.
I don't understand, how can this piece of **** be so stupid. Excuse me, I'm about to blow up.
Okay, how can I fix this problem?
I'm currently rooted and using MIUI rom.
Please.... help me before I end up throwing my phone at a brick wall.
Many thanks for reading this topic (And thanks for barring with my rage)
Solved.
Okay, I lied. It's not solved, just a bit better.
I also have found out now that once I lose wifi signal, Android doesn't auto re-connect. I must go to the wifi setting page (not pressing any buttons or anything, just being on the page) then it re-connects.
I have tried this fix, it still doesn't work.

Raising the top right 2 flaps, according to this image. http://forum.xda-developers.com/attachment.php?attachmentid=668981&d=1311865226
Basically I raised everything.
Any idea what else I can try?
I am using 2.09 HSPL
do you have any objective measure of how weak your signal is?
mine isn't so great either; certainly less than a friend's iphone.
if you go into wifi/ advanced (in winMo), you get a signal quality bar. Mine only registers 100% when i'm literally within about 750cm of my router. beyond that, it drops to about 80% for another 2 metres, then drops to 60%.
i've done the same test on my old tytn II winMo phone and it's about the same, so maybe that's just how it is.
what this means, is that free wifi in bars/ hotels etc. mostly work OK but can be marginal where others are getting a good connection 100%.
i haven't tried taking off the back to bend the contacts up yet as I remember the royal pain it was the last time I had to open my HD2 (to clean a fingerprint off the inside of the lens cover left by a HD2 tech after an RMA).
Perhaps test a couple of the favourite radios & see if get any better wifi reception.
HD2 wifi is not the strongest but if hardware & firmware up to scratch it normally usable even on low registering signals.
My HD2 signal compares about same to a Desire, Topaz & Touch Pro.
my WiFi signal is about ok.. Though Network signal ain't that great.
I have bad wifi signal strength too My friend has 3/4 bars in his LG Optimus One P500 and downloads a torrent with 200kb/s and I can barely see the connection with 1/4 bars and keeps disappearing.
I haven't tried the antenna fix though.
So I've had my S5 for a few months now. It's basically been a dream for the time being.
Now the phone is pissing me off the same way the S4 pissed me off...
Battery life is totally fine, absolutely no complaints at all. My phone lasts for ages except for when I play tons of games on it.
Performance however is quite slow (probably due to lack of RAM).. despite running fstrim, cleaning cache on a weekly basis and using apps like Greenify etc.
The worst thing however is the ridiculous issues I am having with 3G/Data.
I am unsure if it is just my carrier (The largest network in Finland (SONERA)) or if it is my phone.
I made a video here of the EXACT SAME issue with Wifi (data is even WORSE):
http://youtu.be/2zNBV63Dk0U
Basically you see the first 2 pages load up pretty fast. Then what's with the wait on the rest of those pages whilst they are loading?
The speed of my network is 10MB/s up and down. It's a symmetric connection. It shouldn't be slow at all, and ping times are tiny. So why is it taking so long for my phone to resolve the website, regardless of the browser and method of connection (data or wifi) that I use?
Basically my phone will just switch between 3G and H/H+ continuously without actually being connected, or loading pages etc.
So basically I'll be in the middle of the capital city, on Finland's LARGEST network connected to 3G with FULL bars and not have a connection. Yet all around me, people are using their phones without remotely any issue at all on the same network..
Some information about my phone:
Galaxy S 5 (SM-G900F). Stock ROM, never flashed. Towelrooted.
4.4.2. - Baseband G900FXXU1ANE2
Build - KOT49H.G900FXXU1ANE4
Stock Kernel
80+ User Apps installed
Xposed Framework installed
The biggest issue I have is the fact that the Data connection just sucks in 2G or 3G. There's just this huge lag between loading any webpage, where there is literally ZERO data being transferred (I have the speed indicator xposed app), yet the icon just flashes back and forth from 3G to H to H+ and back. No matter what browser I use, and even often on Wi-Fi it's just terrible and there is STILL a huge wait time between pages actually loading. However apps at least seem to download totally fine.
I have my Buffalo N300 router on Wireless N. I am NOT running at 5Ghz, because it drains more battery. My 3G plan is set to 21Mbps, and I should have no throttling or cap. However I RARELY seem to see speeds over 250KB/s and in the centre of Helsinki or anywhere in the outlying (2-3km areas) there's just no data transfer at all. Full bars, but in some cases the entire network will just cut out and say that it is unavailable.
Could it be an issue with my phone's Modem? Could I just flash a newer modem over the current one that I have? The phone is running stock and it shouldn't be so slow, no matter what.
My stupid provider just suggested that I change to a more expensive 4G plan (yeah right, 3G on other providers was never remotely laggy)
Any ideas guys? I'll give you any information that you need to help me out...
..
Well what info do you want from me?
I posted a video of how the pages load so slowly even on Wifi. I told you my router. It's a Buffalo N300. I don't have 5Ghz mode on. It's set to Wireless N. My internet speed is 100/100mbps. I think that is plenty of information.
I also gave my complete phone specs. My knox is 1x1 yes. I gave my baseband etc. above.
What exactly do you need to know about my configuration? It's set to use 3G always. I always seem to have bars of 3G (even if it won't connect) but there is NO data transfer at all. You can see in the video that the speed indicator in the taskbar doesn't show any data being transferred. There's just this large amount of time that it does nothing. The page loading/connection stalls and I have to wait. I've tried multiple browsers too like I said, and more than 1 Wi-Fi network.
If I swap back to 3G or 2G (WCDMA/2G) mode. Then the phone still stays on 3G 99.99% of the time, but there's still NO data transfer. On 2G it will work just slow enough that I can send a whatsapp message. But it won't load a webpage, not even slowly.
My carrier I also explained.. Sonera, the biggest carrier here in Finland, I also even explained the data plan I am on. 3G, 21mbps, no throttling, etc.
P.S. The speedtest in my signature, is my HOME WIFI connection. It has NOTHING to do with my data connection. I'm not talking about my DL speed or throughput, besides those are the speeds I get on my COMPUTER. I get slower speeds on my phone. I am talking about the LAG that I get when I try to open a page. I.E. Why does my phone just stall loading something and make me wait for ages for it to finish? Why does my connection just stop, and page loading just stop 40%-60% or whatever through loading something?
What extra info do you need? You keep saying 'phone congifuration' but I just gave you basically everything. What specific 'phone configuration' info do you need to know?
You know what phone I have, exactly what version, how it is rooted, etc. You know my data provider, my wifi and data speeds. You know the issue that I am explaining that I am experiencing and how it happens. Plus a bunch of other information, what is installed on my phone, my router and its set up. etc. etc. etc.
What more do you need?
Thanks for your reply but. Frankly I think I provided more information than most people do about their problems here.
P.S. Here's another video which shows me getting 12.5x slower speeds than I should be:
http://youtu.be/N0aTikEPbPM
Excuse the exasperation and that accompanies my Australian accent
I got some data issues too.in H+ data just won't move like it should.
I'm using saunalahti.
When i open a web page my 3g turns to h+ . I think that's the way i should work
because nothing happens with 3g.
Nothing mostly happens with my 3G either, it has to be on H to do anything. I am starting to think it's an issue with 'Fast Dormancy' and I might go ahead and disable that.

Yes, you provided considerably more information than most people. Kudos if that makes you feel any better. However as I explained at length it still isn't nearly enough to effectively troubleshoot much. I also spelt out what would be useful to have. Having 60% of the details doesn't complete a puzzle significantly more than 40% would. It narrows things down a bit but you're still in the land of guessing and throwing out common issues hoping that one of them will turn out to be the problem at hand.
There are lots of people who will be happy to pseudo-randomly guess at the problem. And you can try each suggestion in turn until you hopefully hit upon the right one. I'm more interested in methodical troubleshooting which requires much more detailed information. As I described what would facilitate that and you still ask what do I want, I can only assume that you missed reading part of my earlier reply.
Regardless you can either post the details I requested or wait for others to point out how to address commonplace issues that may or may not help your situation.

Are you for real? Practically all of your replies here are "You haven't given us enough information"
You practically know my phone and my data and Wi-Fi as well as I do, from what I have explained.
Now your reply is just paragraphs of you blabbering on about how I still haven't given you enough information for you to help me. If you think you're being constructive here or something replying like this to other people, you really aren't mate. Yes you did explain at length, three times that I didn't give you enough information. Yet you failed, to explain even ONCE exactly what information you want. Except to say "phone configuration" I mean seriously what? That's the most broad term you could possibly use on the forums here. I've explained my phone config, and- actually you know what, I won't do it again. I've explained everything so much and posted TWO VIDEOS of the issues that I am facing. If you seriously don't know enough about my problem then, with all due respect you are of absolutely no help to me what-so-ever.
The worst thing is, I'm usually a patient person and I am grateful for the help I get from other people in the forums here and anywhere else. But every-so-often someone like you comes around and I can't, for the life of me, even fathom as to how to even communicate with you. All of the information is right there in front of you to provide a second opinion or give your personal advice. Yet you're sticking with "You haven't provided enough information". There's nothing else I can do buddy, save actually giving you my phone and letting you look at it.
Also the way at which you seem to post in that I only seem to have 2 options here is really quite ridiculous. That I can either choose to give you more information (What information EXACTLY?) or basically just wait for other people to guesstimate what the issue could be (which I was totally fine with).
If you mean this information:
Or do any testing that might have revealed patterns in your data and wifi rates e.g. speed and latency tests at different times of the day
- What's the point? I explained here and in the videos that this has been happening all the time, for the past month.
with different providers
- I don't have another data provider to test with, I'm not made of money
direct comparisons to other phones on the same connection
- How the f*ck can I get stuff like this? I'm one person on my own, do you suppose I go stand out on the side of the road with a sign on a highway?
ping plots, service menu details about which bands are active and actual signal strengths or anything like that
- Do I look like a scientist to you? How am I supposed to know, and the phone doesn't give me any sort of way natively to even know any of this information
did you do any searches of forums dealing with specific providers e.g. BBR, Hofo, to see if anyone else is having provider issues?
- Yes and lots of people are having the same issues, even someone else replied to this thread stating he had the same issue

That is a ridiculous amount of stuff to ask from someone and I have either given you the details already, or you're asking something that isn't physically possible for me to do.
Personally, I think you're going about this whole 'helping people' thing the wrong way. Like there is some choice between getting your 'professional' advice or something or basically just taking hints and suggestions here and there. I don't remotely agree with the way you post on the forums here. I've provided umpteen times more information than just about anyone else on the forum here, and no, that isn't a compliment to myself. It's a fact.
Ugh, this whole situation is just absolutely ridiculous. It's one thing to wrestle with a phone that isn't working correctly, but then when I come to the forums here for advice, I get replies like yours. Supposed helpful replies that are really just basically spam, constant reiteration of a moot point with equally absolutely no clear, or distinct point, subject or purpose to them at all.
Maybe you should take your own advice and be more specific with what information you want from people if you are going to bother to reply to them at all. Rather than just responding continuously with "We need more information". You represent 1 person on the forum here, and your ideas or advice are no more important or relevant than anyone else's. If you're going to try and help someone, don't confuse a person into thinking that they only have 1 source from which they can receive assistance and that they must first comply with your vague requests before they can get any assistance.
As for this now failure of a thread and my now wasted time replying and taking videos perfectly illustrating the problems I am facing with my phone. I am subsequently going to abandon this thread, unsubscribe from future replies and leave it here as both a documented source that there is an on-going issue (as many others have stated) with data and wifi lag and that for anyone else to perhaps understand your methods of posting better. Because I sure as day don't.
Thanks anyway I guess.
As for anyone else with the same issue. I am going to disable 'Fast Dormancy' and see if that solves my problem. Good luck to others facing the same issue.
..
ignore fffft he has issues.
have you tried your sim in other phones? do they get good data speeds? if i were you i'd flash a modem update and see if that fixed anything. maybe try a prepaid carrier on your phone and see how its network speeds are.
Happened to me too - could be an app on your phone. Check settings to see which apps or using most battery and background services.
Or do what I did, and get an uninstaller to uninstall 70% of your apps you don't use - could make a massive difference!

Gosh.... Can you tell us own many more phone are connected to the same cell as you? This is already a difficult issue to troubleshoot, I guess your videos and long posts are useless. How can you distinguish between a mobile provider problem and a s5 problem?
fffft warned you!
Did you tried the cleanmaster solution?
Having the exact same problems in the US with sprint, I can have 3 or 4 bars of signal and apps report network failures and no data connection, I do not usually have an issue on wifi, but it does happen from time to time.
Rooted with towel
no custom recovery
Multiple frozen system apps
Purchased launch day from Sam's club
Xposed installed, I've disabled most of the modules I installed as they don't seem to work, especially any listed as Samsung specific
Still using TW
Often when the data loss issue occurs the 3g or LTE icon in the notification bar completely disappears, but the signal bar stays in 3-6 bars.
Current battery life seems to have no effect on the issue.
Mine is not just data, there are times the entire phone freezes and becomes unresponsive, taking 20-120 seconds to respond to pressing back or home even, and I get no response to pulling down the notification bar.
I do not use any task killers or battery mods or apps, I did notice a significant increase in occurrences approximately 3 weeks ago and the only thing I recall that I did then was to install hangouts dialer.
The troubleshooting I've done makes me believe the device is "detecting" high temps and turning off or slowing the CPU /GPU cores, thereby causing the apparent 'Lag'.
One incident happened last night, where no part of the phone felt hot, my game did not lose connection, but was on Wi-Fi, but I was getting 1 frame every 2+ minutes for 6 or 7 minutes, then the phone rebooted.
I have started making it a habit of opening Rom toolbox and checking the CPU current settings, during these issues I have never seen the CPU max over 1728 MHz.
The only information I located in a cat log was that frames were dropped and how many. Nothing about temperatures, many lines about IP addresses failing to respond. I do not have a saved catlog handy, but attached are a couple screenshots of data fails with good signal.
If you look, you may notice the warning notifications, those are sync errors with Google photos wanting sign in information for alternate accounts I have on the phone and don't want duplicating my phot backup too (some of my games I play 3 or 4 different accounts).
I will be happy to do any testing suggested as soon as I can and provide additional requested info without insults.
Necropost... Still having this issue, I've been on MOAR, Pac ROM, and Slim. 4.1.1, 4.2, & 5.1.1 android versions. Same problem, on Wi-Fi and Sprint. Phone is about to hit 2yrs old in April. Will be my first and last Samsung I guess... I've had a lot, Nexus is next I think...
