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.

Hi everyone
I am not sure if it is really nexus 4 or android related, however, maybe someone can point out something to test or analyse this further. Maybe even has the same issue.
Therefore I am already thanking all of your for taking the time to read this.
I am on nexus 4 with 4.2.1 (Baseband: M9615A-CEFWMAZM-2.0.1700.33, Kernel 3.4.0-perf-ge039dcb, build JOP40D).
I had the samsung galaxy nexus before (with a normal sim card) and went to the shop after buying the nexus 4 to get a (new) micro sim.
I dont have apps that "optimise" the battery life or such and may tamper with the signals (at least I dont have any to my knowledge).
Problem at hand:
WiFi signal is perfectly fine. However, whenever I go out of range of a WiFi the "normal" GSM signal is not taking over...it shows bars, but they are grey instead of blue. And whenever I go online then, it says I am not. The only thing I can do is either reboot (which I did only once so far for resolving this issue) or airplane mode on and then off again. After that I am connected again. I am not quite sure if phone and messages would work and only "internet" is affected.
Does anyone experience the same thing? Anyone an idea what that could be or what I can further check/test to verify?
Thanks a bunch

Hi,
I purchased the s4 through radio shack 4 days ago. I was having issues with the wifi staying connected for more than a minute. After doing research and reading forums I came to the conclusion it was my router. I've reset it and done firmware updates and changed security to WEP and wifi issue was resolved. However now it is constantly scanning for a wifi network even though it's already connected to one. Have called samsung and radio shack sbout this and am getting various responses such as it is normal, or no it is not normal let's try a a hard reset to see if it fixes the issue. So this forum is my last resort before completely resetting the phone. Should wifi be continuously scanning even if connected to a network or not? Thanks

Mine still scans for Wifi about every 4-5 seconds even when connected to Wifi. It seems to be normal and believe it did this on my S3 as well. Unless it is draining your battery I wouldn't worry about it. Also, it may only do it when you are in the Wifi settings and not when you exit but who knows. I get great battery life so it is something I'm not going to worry about.

have you asked if it Is normal? Im pretty sure the scanning is affecting my battery life but but not
sure how to check whether it is or isn't. Just dont want to find out months down the road that I have a defective device. Will resetting it fix the?

I have not asked because my battery life doesn't seem to be affected by it. Also, I think my S3 did it also. From what I find when doing an internet search everyone else is seeing the same thing so almost positive it is made this way. When I look at the breakdown of battery usage (Settings->More->Battery) Wifi is only using 6% of my battery. Look and see what is using battery on yours. If you need more detailed information on what is using the battery than get BetterBatteryStats from Play store to help pinpoint it. There is a forum just for it where you can post and get help figuring it out if need be.
Also, as for resetting, I just did a factory reset yesterday and it still scans when in the Wifi settings.
The scan interval is probably cooked into the build.prop somewhere by Samsung. Usually apps like Blade Buddy and Rom Toolbox Pro can change it but BB is not compatible yet with the S4 and Rom Toolbox doesn't show the scan option in the build.prop list. I looked at a few of the custom TW roms and not finding any changes to that listed in any build.prop tweaks.
If I had to guess would say there is something else on your device using the battery but using BetterBatteryStats can pin point it for you.
**Edit....From what I am reading it seems there is nothing in the build.prop to edit. A line needs to be added in to change the default scan interval. I'm not 100% positive on this but seems to be the case.

OK I've looked at battery usage and and wifi is at b 4% and screen has the highest percentage eventhough I have it at a lower resolution. However when I click on wifi from the battery setting it says it has only been connected to Wifi for 4hrs. 32 minutes . I've had wifi turned on since I got home last night. Could that be the issue? I did charge the phone overnight unless it shuts off while charging but still my emails would have to sync every hour. Do you know why it would say it's only been connected for 4 hrs if I've been home much longer than tgst? Thanks for the help. And also did you reset your phone due to the wifi scanning?
THANK YOU

I don't know about the reported length of time for WiFi. Mine seems to be accurately reporting when I connected to WiFi this morning at work till now. Maybe it disconnected and then reconnected for something? Do you have multiple bands in your home (2.4ghz & 5ghz) to where it could have jumped between them? Did you walk outside and out of range for a sec? Maybe for some reason it had a hiccup and got disconnected and reconnected. Not sure.
Also, I did a factory reset for a Play Store issue and not because of the WiFi.
Wifi scanning every 5 seconds on my Galaxy s4
Jellybean 4.3 has been responsible for one of the highest complaints to hit android since androids launch.
Wifi overscanning
Battery management
HDMI Completely not working
The list goes on, this is all because some idiots wanted to rush jellybean out to accommodate for the introduction of the Samsung Gear. As a result of rushing it's release many elements were not tested or even included in the update of our much loved now screwed galaxy s4 's
Someone better get there act together and roll out a TESTED release to address all of these screw ups!

When this post was made 7 months ago, the S4 was on 4.2.2 not 4.3. Way to revive an old invalid thread. Also, all the things you mentioned work great on my phone so calm down a little.

That's funny because as a senior member, your reply seemed neither helpful nor relevant to what I said about the Galaxy S4 being affected by the latest Jellybean 4.3 update (whether I posted on an outdated thread or not) The subject matter remains relevant because the Wi-fi over-scanning while connected is still very much a current issue.
Many users have complained about the numerous errors currently being recently experienced in the latest 4.3 update, many of which have now been announced on the Samsung support forums. I'm in the UK and I see you're in the US. that in itself could make a hell of allot of difference in the errors that UK users may be experiencing. I'm also on T-Mobile and that could also have implications to the version of Jellybean subversion that has been installed.
Telling me I should 'calm down' (just because you're not experiencing any issues with your phone) is not the sort of condescending remark expected from any senior member.

Well, seems you don't have the l720 so why are you paying in these forums.

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?

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...

Now that I've got the Moto X Pure Edition activated, I've been able to work out some of the kinks inherent using it as a daily driver. One noteworthy issue that remains is an odd bug where the device will completely lose connection to the Internet on both a WiFi and cellular data connection, usually after transitioning between types of connections. When this happens, an exclamation point is displayed next to the icon representing whichever connection is currently active and nothing is able to transmit data to or from the Internet or even my local network.
Rebooting the device always fixes the problem, but this issue is materializing a bit too often for my liking, which is usually once every time that I return to a WiFi network after being disconnected from one for some time (more testing may have to be done to confirm exactly what triggers it).
The device is running the stock rom (rooted) and the stock kernel along with the usual tweaks (ad-blocking, Xposed framework, audio fixes, etc.). Anybody seen this before or know what might be causing it?
UPDATE (3/1/2017)
Figured it out! The problem appears to have been caused by my failure to whitelist certain applications in PowerNap. After following the instructions found in the Moto X Pure Edition power optimization thread, the problem appears to have vanished. I don't know if it was the Google Services Framework, JavaTcmdHelper, Android System, or some combination of those that needed to be whitelisted, but the problem has vanished. At least one of those must be responsible for verifying the validity of an Internet connection in sleep mode, which would cause the device to become confused when it would wake up with a different connection that it hadn't verified (that's my theory at least).
At any rate, it is no longer an issue.
Update (Later on 3/1/2017)
Well, it looks like it might not be fixed so well after all. A couple hours after arriving home today, I went to use the device and saw the dreaded "!" next to the network indicator. Still, two days is longer than it's ever lasted before. I've cleared the cache and dalvik/ART cache to see if something in there might be gumming it up and will add another post to this thread if the problem returns.
Still an issue
Looks like it might not be fixed after all. I lost connection again the other day in a parking lot and once more today after getting home. Any ideas as to what could be causing this?
I just recently got my x pure. I've seen this issue on mine too.
Another one!

Interesting. Are you running the stock Rom? Rooted? Amplify/Greenify/PowerNap?

I'm unlocked and rooted. Running validus 7.1.1 ROM.
does your configuration look anything like this?

That too is interesting. I'm running the stock Rom, (rooted) so we can probably eliminate that as a potential cause. Given how little reference there is to this on the web at large, the problem is probably caused by a common app or setting (or some kind of unfortunate combination) running on both of our phones.
All we need to do is figure out what kind of "unusual" stuff our devices have in common. I'll rattle off a list of software and settings that might be out of the ordinary or network-related; you tell me if you're running anything like it on your phone.
AdFree
A.R.I.S.E. audio
FolderSync
Ice Box (Motorola Update Service is the only frozen app)
TOTAL Wireless My Account App
Pebble, MyTracks, and Pebble MyTracks
SlingPlayer (this one sometimes wakelocks)
Titanium backup (I tried restoring some WiFi access points once, but it didn't work)
Xposed Framework with Amplify, Greenify, and Power Nap installed and configured as instructed in the Moto X Pure Edition battery life guide thread OP. I've also got MinMinGuard and YouTube AdAway.
As far as settings go, I've not got much in the way of unusual configurations. I enabled the system UI tuner to get the battery percentage and the extended developer options to try out multi-window, (and to change the animation scales to .5X) but everything in there is still pretty much stock.
Does your configuration have anything in common with mine?
Close, but no cigar
It got almost 8 days this time before it happened again. I thought that maybe switching to the legacy DHCP client had done the trick, but that was apparently not the case. Any ideas as to what could be causing the issue or how to fix it?
Or, if you're having the same problem, can you look at my list in the previous post and tell me if any of the software or settings are similar so that we can narrow down the cause?
I have had this problem appear about three times over my 13 months of ownership and all three times was when my bootloader was still locked (obviously running stock not rooted). Never found a solution except to reboot.i only unlocked and rooted my device about a month ago.
Anything familiar?

Interesting. Between that, my findings, and the fact that @inkdaddy66 was having the problem on a non-Motorola Rom, I want to think that we can eliminate the Rom software as a cause. Did you see any familiar software on my "potential troublemakers" list up in post 6? I'm thinking that if we can find a common program or workflow, then we'll be able to narrow down the cause of the problem.
In the meantime, I'll try posting in the general Android troubleshooting forum here on XDA and see if anybody there has seen the problem or has any troubleshooting tips.

Nothing used from your list except system UI tuner when I experienced the problems. That would leave either a ROM and/or hardware issue IMO.

Hmmm... That's also interesting, but I just don't see how system UI tuner could be harming anything. Do you have any other apps or settings at all that you think could be causing the issue?
If this were anything other than my primary, I'd hard reset and troubleshoot that way, but I don't exactly have the time to pull the rug out of an otherwise-working setup right now, so this is going to have to be done the hard way (or, in the case of hardware glitch, lived with).
At any rate, I discovered a new symptom earlier in the week. This time, Internet connection was lost, but only for WiFi, so the connection would actually fall back to Cellular and still continue to work. As before, toggling the connection had no effect, but rebooting the device "fixed" it. I thought maybe it was a fluke, since we'd had an AP hiccup over the weekend, (I refuse to reboot that thing because I'm going for an uptime record) but it happened again on Wednesday, so I'm not sure what to make of it.
Side-issue aside, I'm beginning to wonder if it's some kind of combination of network behavior and usage pattern that brings the issue about. It seems like if I stay within range of the WiFi network, no issue develops, but if I move out of its coverage and don't touch the phone for a while, that allows for ideal conditions under which to replicate the problem (sometimes). I haven't nailed down a consistent pattern yet, but the problem does emerge more often when I'm returning home than at other times. Any thoughts?
Update (3/24/2017; 12:32PM)
Scratch that last part about the issue only being triggered upon "arriving home." The problem happened again this morning, in the same general area. First, no WiFI, then, after resetting the connections, no cellular either. I captured a LogCat before rebooting this time though. Anyone want to take a crack at sifting through that to see if it offers any clues?
I lose cellular data, from time to time, I don't kow if I'm losing WiFi capability also, because I'm on the road when this happens.
It takes a reboot or switching in and out of airplane mode to regain data.
I have had this happen on TruPureXMM ROM and stock-rooted Marshmallow.
I have not spent much time on stock-unrooted, so i don't know if it would happen then, also.
Possible fix
Just to follow up on this again, I have finally reached the eighth day of uptime without the problem materializing, which is the longest that I was able to go before without it happening. This time, I went in to the developer options and disabled "Cellular data always active." I'd give it another couple days to know for sure, but if this sticks, then I think we might've found the fix!

If your trouble is isolated to just one connection and/or cycling the connection brings it back, then the issue you are experiencing is unrelated to the one described in this thread.

Cellular data always active should never be on (it's disabled in stock rom), except if you have VoLTE only with no fallback to 3G or 2G (Jio is the only provider that comes to mind, but this phone doesn't support their service anyway) or otherwise unusual scenarios I can't really think of.
Huh, and CELLULAR DATA ALWAYS ACTIVE (for faster network switching) sounds like such a good thing.
Mine was selected on.
My loss of data happens in the same spot, usually, but is not leaving wifi. Perhaps it is a tower to tower handoff spot.
I turned it off. Time will tell.
Thanks, fellas!

Always on is not necessarily a good thing. Reality is that when you lose or turn off WiFi, mobile data should only be delayed only by a second or two. There is no real benefit to having it on except for maybe VOLTE.

Actually, it's a battery killer more than anything else... It keeps cellular data active even when on WiFi.
It is possible it's a tower thing though. I have noticed at this one hotel I stay at frequently people tell me they call and it rings or just goes to voicemail even though I have good signal. After investigating it a bit, I'm in a spot that has nearly identical signal strength from 3 towers and it's a metro area so there are 4+ bands accessible... I've seen times watching LTE Discovery where it keeps switching bands and towers for 30 to 120 seconds or so, like it can't make up it's mind what to talk to because it's confused, then it locks on for a while before it starts it's cycle again. During those cycles I think is when people can't call me, can't really say if it affects internet or not since I tend not to use my phone too much in the evenings when I'm on the road (usually on laptop).
Uptime record, but... it's back

Interesting. I thought for sure that I had the default settings checked in there, but maybe I did change it early on and just forgot. Either way, waiting an extra five seconds to establish a data connection isn't that huge of a deal for me, so I'll leave it off anyway in exchange for battery life when the signal's poor.
At any rate, however, the problem has returned. I was just a few hours short of 9 days of uptime and really thought that I was out of the woods with this problem, but it has returned once again upon returning into range of the home access point. Looks like we're back to the drawing board on this one.

So you're having the same problem too? That makes at least four of us now. Do you mind sharing what Rom and flashed tweaks (Xposed Framework, A.R.I.S.E. audio, root, etc.) you're using as well as any unusual software or settings? Anything in common with my list on page 1?

I think we've established that my issue is different, but it has occurred on TruPureXMM and stock but rooted Marshmallow, both with Substratum, Xposed (Gravity Box only) and Viper Atmos.
Same as you =Titanium Backup
*another* new strategy (sigh)
For this week's shot in the dark, I'm going to try manually switching WiFi off before I leave anyplace covered by an access point. Since the problem seems to occur most often when connected to WiFi or when connecting to it, maybe this will make some kind of a difference.
