If You Cannot Access Google From Your Verizon 10.1 READ THIS

I have gone through three Verizon Samsung Galaxy Tab 10.1's in the past two days (since the Verizon release).
PLEASE NOTE: this only pertains to Verizon devices while trying to access Google pages using your device's DATA PLAN.
EVERYTHING works fine when you are connected via WiFi.
The first time I opened the browser, it tried to auto-log me into the default Verizon/tablet Google webpage. It never got there. I tried to access other pages in Google until I tired myself out. I tried installing Dolphin, Firefox, etc and still no go. I then tried connecting to WiFi and was able to access Google, so I figured this was probably a 4G issue. So I decided to call Verizon as I was somewhat sad about my new toy. Verizon had no notes or information at the time except for wiping my device a few times. Nothing worked. I was advised to return it, as it was deemed defective by Verizon's Tech Support.
I brought my device in and swapped it out. This one did the exact same thing. I tried logging onto Yahoo and it worked though. I showed the Verizon staff inside the store (because they had been fiddling with it for over an hour) and they were very happy to see that I found a way to make it work. I then tried accessing other sites and it also worked. About 10 minutes later, the staff had checked their Tech Notes on their Intranet or whatever they use, and a note popped up about a very large number of other customers reporting this problem.
Verizon said that they had a server issue and that was why this was not visible in their "notes" earlier. They said they are working on the problem and should have a way to fix the problem very shortly. One of the Techs their said I would be lucky if it happened in the next update. So we will see what happens.
Again this is only affecting a small portion of the Verizon Tab 10.1 4g LTE users at this time. And only when you are connected to CDMA or 4G. If you are having these issues with Google while on CDMA 4G (your data connection), just use your WiFi and everything should work just fine.
Don't cry. It will all be okay.
PS: I would like to apologize in advance if this post is not in the proper section. I am sorry.

I personally do not have a Galaxy Tab (WiFi Only) for either the 7 or 10.1.
But my ex-wife has the WiFi Only version and she says that there is not as many processes running in the background on her WiFi Only Tab (compared to mine). I would have to guess that this has to do with the Provider, but I could be totally wrong.

I have the same issue...
I wanted to chime in on this post to let you know what I've found out and to also give you a background on the experiments I've conducted both locally and with the Verizon techs.
I purchased the new Samsung 10.1 4G LTE tablet 2 days ago and have the same issue where I can't access google.com or anything related to the google domain via a browser when connected to the cellular network. Over wi-fi it works fine, but not over the 3g network.
That being said, I called Verizon tech support (no one had been aware of any issues with the tablets), and explained what was happening. I was escalated to a very good tech who walked me through several tests. In addition, I had two people in my office that had other tablets (a Verizon Xoom and an iPad2). This setup the perfect test bed.
Here's what we found out:
1. My Samsung 10.1 4G LTE can connect to google.com via wi-fi (both via a router and cellular hotspot).
2. My Samsung 10.1 4G LTE cannot connect to google.com via the cellular connection.
3. We did a factory restore on the tablet but that had no effect.
4. I turned on the Samsung 10.1 hotspot and had the other tablets try to connect to google.com using my cellular connection to see if it was something on their server blocking the domain. Both their tablets connected successfully.
5. I downloaded both Firefox and Dolphin browsers to see if it was in the default browser. Both didn't load google.com.
6. Tested all the google apps on the Samsung and all worked via wi-fi and cellular connection.
The only thing I couldn't try was to load google.com inside a 4g network. I live in South Texas and the closest 4g network is 2 hours away.
So...
I was told to take back the device to where I purchased it and exchange it to see if it was the device. It took about an hour to see the local tech, so in the meantime, I though I would try the display tablets in the store to see if the problem existed with those.
All the Samsung 10.1 4G LTE devices didn't load google.com over the cellular network.
I felt like I had reached the limit of what could be done, but I still was interested to see if it would work in a 4g network.
So...
I had one of the techs call another Verizon store in San Antonio (a 4G environment) to have them load google.com.
IT WORKED!!!
My conclusion is that there is an issue with the tablet's software that is preventing google.com from loading via a 3g cellular connection. This explains why some people can get it to work (4g network) while others can't (3g network).
The tech went ahead and exchanged my device for a new one (which by the way, still didn't load google.com as expected) so he could send it back to Verizon and start the process of getting this rather embarrassing situation fixed...hopefully.
The ironic thing is, this only affects loading google.com and no other website. Being a google supported device, I would expect this to be resolved quickly.
I hope this has been helpful.

UPDATE: My 10.1 is working FLAWLESSLY now.
Thanks for the chime in. As I had said, the Tab worked fine with Google when connected to wifi, just not when connected to the Verizon network. That was the whole issue. The software issue seems to be a part of the issue, BUT I HAVE LEARNED THAT THE 4G LTE SIM CARDS MAY WELL ALSO BE A HUGE ISSUE (ALSO HOW THEY WERE INSTALLED).
The way the SIM card is installed could have been an issue, but there also could have been an issue with certain "batches" of 4G LTE cards that Verizon was given. To be perfectly honest, the first tablet I had that had this problem, I returned immediately and asked them to just replace my device and give me the card to take home so I could install it myself (I had been the only customer that day [opening day] to pickup a 10.1 and nobody there really knew how to set them up. They know the type of work I do and had no issue with it. I followed directions exactly as described, and still had the same issue.
It really disturbed me though when I had brought my first 10.1 back and they spent an hour into closing trying to figure out what was wrong (all 5 employees). The man who installed the card in the first place really wasn't even that sure if he had done it correctly. I don't think everyone was really too up-to-date on how to get these Tabs up and running with the LTE out of the box.
Verizon later told me that problems with the SIM cards themselves could be corrected without having to manually service the device.
Who knows.... All I know is that the issue is no longer a problem for me. If anyone is still having problems in this area, please try and give me any details you can besides what has already been said. This way I can forward the information to my colleagues at Verizon and Motorola and update them further.
PS: I had also just learned that if you lived in an area where 4G was not available, but was suppose to be in the very near future, you could have also had some "issues" with your 10.1. Nothing too specific, but there could be a handful of odd issues concerning new and upcoming 4G locations. That's about all I can really say.

Chiming in here. I've had the same issue with not being able access Google sites while on CDMA (LTE coming in November locally) since I purchased the GTab 10.1 LTE a week and a half ago. I have read posts on several forums with others having the same issue. After seeing this post today I tried once more using CDMA and it works. I have not made any changes or messed with the SIM card on my Gtab. Verizon must have done something on their end.

[Q] WiFi Troubles?

Ok before I begin with this thread I'd like to say although I'm a new user, I have been on XDA for quite some time. My old account information has been lost.
Basically, my WiFi on my SGS4 I9505 is working when I'm at home, but I can't connect to the one at work. It used to work flawlessly, connected without me clicking the buttons, but now it says "Connecting" then straight back to "Saved"
What have I tried?
- New roms, different Android releases
- Searching forums
- Completely re-flashing the stock firmware via Odin
- Multiple modems via Odin
No matter what I do, I can connect at my home modem but not my work one, all of my work colleges are connected, I've had my friend try connect it (he was the man who introduced me to flashing ect) and he hasn't a clue.
Any advice would be appreciated & the reason I'm creating an entirely new thread is due to the fact my WiFi works at home so it's not just a bug there. Thanks.

Same exact thing happening to my S4 SPH-L720 (Sprint). Using NegaliteROM 4.4
Tried:
-Re-flashing ROM
-Updating PRL & Profile
-"Forget Network" and re-typed password (confirmed with IT dept password hasn't changed)
- Cleared google account ("Backup and reset" portion) then re-synced after failed login.
And as irscotty stated, wifi works EVERYWHERE else and it just goes straight to "Saved Secured"
Is there a way to reflash the Wifi card to an older Firmware? I don't recall updating it manually, and I believe that is the only way to update it (correct me if i'm wrong). If so, is this even advisable....
Thanks

The only other thing I can think is perhaps the contract provider has cut down the WiFi limitations?
Not sure if that's even possible but every other modem I connect to is just a few feet away, the one at work is perhaps 5-8 metres. But was working 100% prior to this, and the signal strength is saying "Strong" just wont connect

Yeah I'm literally 1 yard away from the router. What do you mean by cutting down on limitations? Blocking the amount of mac id's from the router homepage ?

No it has been known in the past for your data providers to cut down your WiFi range to force you into using their data, as opposed to WiFi.
Although to my knowledge, this can only be done through an OTA update on the original software (not custom)

My current solution to this is by changing my Mac address and have successfully logged back in. Seems like was I indeed being blocked. But have no confirmation yet. I use a program called MacChanger (requires root) and hard change my ID when I'm at work. Has been working for a few days now.
Good luck

[Q] Wifi Slow on Galaxy S5 - Strange Issue, Please Help

Hi All,
I was wondering if someone can help me. I am having a bizarre problem on my Galaxy S5, which so far has stumped Verizon, Samsung and Time Warner Cable Tech Supports.
For some reason, when I'm connected to my home Wifi network, certain apps run very slow. Basically, if you open an app like Facebook, Instagram, or the Google Play Store, a lot of the icons, pictures and thumbnails all show up gray, and either don't come up at all, or take forever to load. As soon as I turn Wifi off and switch over to 4G, they all pop up almost immediately. I've also noticed this problem on Google Now. You tap the microphone, say a command and it gets stuck on "Recognizing..." for a long time, and quite often comes up with "Can't reach Google at the moment." Again, it's only certain apps. Other apps like my web browser app don't seem to be affected.
This doesn't make sense to me, because I also have a laptop and my girlfriend's Galaxy S III connected to my Wifi network and they don't have this problem. I've even busted out my old LG Spectrum 2 and sure enough, these apps load up lightning quick on it. I've done an internet speed test on my S5. On my Wifi I get a 19ms ping, download speeds of 18 MB/s and uploads pushing 2 MB/s. When I'm on 4G, the ping is 40ms, and the speeds are only 6MB/s and 0.7MB/s respectively, so the Wifi theoretically should be way faster.
I spent over an hour on the phone with Verizon and Samsung Tech Support, and after trying a ton of different things, including a Factory Reset, they determined it was probably the device. Since I'm under warranty, they sent me another one. I got it yesterday and tried it...yep, same problem.
Just out of curiosity, I tried it on the Wifi at my workplace. Wouldn't you know it, the problem isn't there. But, I don't understand what could be wrong with my home Wifi. I've got Road Runner Turbo internet from Time Warner w/download speeds up to 20MB/s. I've also got a really good modem/router that cost several hundred dollars. And, like I said the problem doesn't seem to happen on other devices.
I've searched the internet and have found almost nothing on this. Does anyone know of something I can try? Here's everything I've tried so far:
"Forgetting" my Wifi Network and Reconnecting
Resetting the Modem/Router
Clearing Data and Cache on Affected Apps
Phone Factory Reset
Trying with another Galaxy S5
Switching from DHCP to Static Connection on Phone
Switching DNS to Google's Addresses on Phone (8.8.8.8 and 8.8.4.4)
Tinkering with the Modem/Router Security Settings and even Disabling Security
Changing the Router Bandwidth Settings
Changing my Router's Broadcast Channel - Have Tried Several Different Ones
Calling my ISP and Upgrading to a Higher Bandwidth/Speed
Here's my hardware details:
Phone - Verizon Galaxy S5, Unrooted, Running Stock Kitkat 4.4.4
ISP - Time Warner Cable, Road Runner Turbo
Modem/Router - Motorola/Arris SBG6782-AC
Thanks so much in advance!

Watching with interest.
Have a similar situation with my s5 900f international running latest NeatRom.
Some days better than others even when using home sky fibre optic and no drop in speed from router.

Had to get a new router
Ok, so I finally fixed the problem...in a manner that I wish I didn't have to resort to, but it seemed like the only option.
Let me start by thanking Rukbat from Android Central. I posted this topic there too, and his response was very helpful. Here's a repost of it:
Talk to Verizon (the tech people in the back, not the sales associates) or the Time Warner people (same thing - tech people) and see if anyone has an old Linksys or D-Link wifi router you can borrow for a day. (I'm using a Linksys WRT54G at the moment, and in router years it's as old as George Washington's corpse.)
From years of experience, writing communications code, playing with my phone, routers - and looking at my calendar - I'm guessing a bug in KitKat that shows up only with some apps. My almost new Linksys EA4500 started showing this problem almost as soon as the phones updated to 4.4.2, but the apps all work fine on old routers.
If an old router solves the problem, you can get a refurb WRT54 (G or GS) for the $25 range on Amazon (or maybe TW has an old one they'll let you use with one of their modems).
The Facebook app works just fine on mobile data, AT&T hotspots, TMobile hotspots - but not on new Linksys (supposedly the best) routers, and I've heard reports of the same problem on the newer D-Link routers, also supposed to be top-of-the-line. (I actually left the app running for 12 hours once, just to see how long it would take to update. It's more than 12 hours, because it still hadn't done anything. But standing in the parking lot at a Sam's Club, with a barely usable AT&T hotsopt signal, it updates in a couple of seconds.) AT&T connected me to their in-store wifi (which is secured, so of course they deleted the connection after we checked it out) and Facebook updated immediately. Speedtest.com shows over 14mbps download and pings running from 15-50ms with my new router that doesn't work with facebook, so it's not the connection, it's not the wifi signal itself, it's either a problem with certain apps or a problem with the 4.4 wifi firmware. Play store downloads are slower on the new routers too, but not too bad. just noticeably slower. (If I set up a guest account on the router it works fine, though, so it's not a bad router. It's just a pain to have to sign into the guest account every so often.)
This is the reason systems analysts turn grey at a young age and have bald spots. Problems that don't seem to make sense, and people in a position to debug them who can't or won't. I can reproduce the problem at will (which is the difficult part of fixing a problem), but there's no one interested in fixing it.
I ended up just getting a different router, as he suggested. From what he's describing, it sounds like some routers just don't play nice with some newer phones, for no apparent reason at all, which is both discouraging and frustrating at the same time. And I've come to the conclusion that my router is one of them. After spending hours on the phone with technical support from Verizon, Time Warner, Arris and Samsung, no one could find a solution for me.
I will say that I did find some hints from other places online that tweaking certain router settings will fix this problem, but I think I kind of nipped myself in the **** by not doing my homework when I bought my Arris modem/router. This router is locked down pretty tight from changing certain settings. You can't disable IPv6, which some people say fixed the problem. Someone else suggested enabling IP tunneling, but I don't see this setting on my router. Somewhere else, I read that this is the same thing as Port Forwarding, but I really don't know what port you would have to forward to a phone. You can't even update the firmware on my router, as Arris only provides it to cable ISPs...and they won't push it to customer owned devices. I don't even know why they sell this model to the public if that's the case.
So anyway, I just bought a much cheaper Netgear router from Best Buy, and wouldn't you know it, it works great! I think that it even outperforms my Arris. I guess the moral of the story is be careful about what you buy.

Update - problem solved!!!
I cannot believe this. I managed to get my phone working yesterday with my old Arris modem/router. I didn't even have to tweak it, or try to disable IPv6 or anything.
It turned out that the problem was my phone's SIM card. When I first bought the phone, I ordered it online and I remembered that it came in the mail with a SIM card. But, when I placed the card in the phone, it wouldn't activate. I probably should have called Verizon at that point to ask what I should do, but I ended up just taking the SIM card out of my old LG phone, and putting it in the S5. It looked the same to me, so I didn't think it would matter.
Then, not too long ago, I noticed that certain apps were saying that I needed an "Enhanced SIM Card" to use them, so it got me thinking, maybe I should have used the card that came with the phone. I called Verizon, and sure enough, they said that the card that came with the phone used much more updated technology, which is a better fit for the phone. So, they got it activated for me, and now not only do all of my apps work, but the slow Wifi problem is gone too! I didn't even know that the SIM card can affect Wifi. But anyway, this is great! I can take my new modem back, now.
I would ask anybody who has this same problem if they are not using a SIM card that came with the phone. If you are, it could be that you need a new one or more updated one. I believe most carriers will give you a new one for free. You can also check to see if your card is outdated in a couple different ways. Try opening an app like Softcard, and if it says that you need an Enhanced card, then your card is outdated. Also, check the numbers on your SIM. According to Verizon, in the US, the card should have a handful of numbers, followed by FIVE zeroes. If there are any more than five, it is an older card. It might be different for different countries or carriers.
Hope that helps!

Grrrr....spoke too soon. It worked fine for about a week, but now it's doing the same thing again, even with the new SIM card. Switched back to the newer router. Guess it's something with the Arris router after all.

[Q] Need help - Unlocked Japanese Note 3 no longer works!

Hi All,
Please help. I'm a rookie at rooting and have an unlocked Japanese Note 3 through AU (my Japanese service provider). I was in a rush and paid someone to unlock it before heading back to the States last year. The phone works with my AT&T sim card but when I am back in Japan (with Japanese sim) I am constantly being dropped from the network. 4G service usually works for internet, etc, but I cannot make/receive phone calls and only occasionally can send/receive text messages. I need to know if I should re-root the phone (and leave it rooted) or just do a factory reset (or perhaps change some other setting to get things working again)? The problem with a factory reset is that it will probably re-lock the phone and I don't have a code.
Strange Detail:
Whenever I try to dial a number, the name of a Chinese Province shows up under the Contact's Name. This suggested to me some network issue where the phone somehow thinks it's in China (though texts still kinda work...) and doesn't connect correctly to the Japanese network.
Details:
Model: sm-N900J (per the download screen) i believe this means it has a SnapDragon Processor
Knox warranty has been tripped (apparently by the guy I paid to unlock it originally - is that bad?)
Android 4.3 (looks like I'm still in the original version of Jellybean. Should I upgrade to Kitkat or Lollipop?)
Other Issues:
As of two days ago, the phone now restarts after about 5 minutes of use. Like many Note 3 phones, it's always done the occasional random restart (another reason to root?) but now it's making the phone almost unusable. Also, since having the phone rooted/unlocked/re-rooted I always get a series of warnings upon start-up. Typically, standard Samsung apps like S Planner, Calendar Storage, Keyguard and Index Service have stopped. I have never been able to use the Calendar (or other basic apps) since it always crashes. Is this an issue with Knox clashing with something from the original root (I still see SuperSU loaded -but "turned off"- in the apps menu)?
Idealy...
...someone can help me decide the best course of action (Root, Reset, Other), and how to make sure I can connect back up to my Japanese network properly. I think I'd prefer to root since what I want is an unlocked phone that works smoothly, with good battery life, little to no bloatware, a custom theme and a working S pen. If I root, what's the best method (already have SuperSU apparently) and which ROM and version of Android would be the most stable?
Main Issues Recap:
No connection to phone network (or limited 4G internet).
Phone restarts every few minutes.
Many Apps crash upon Start-up.
Thanks in advance!

So, here's an update that someone with a similar problem might find useful...
Japan uses CDMA for voice and GSM for LTE Data. Somehow (probably through using my phone in the states on a GSM network) the phone was no longer connecting to the CDMA network. Since I'd gotten no responses and felt like there was a good chance that a factory reset would not reverse the sim-unlock I'd stupidly paid to have done, I did a factory reset. Despite appearing to have solved my Index Service, Calendar Storage, S Planner crashing issues, I was still having the exact same problem of LTE working but no CDMA network.
Somehow I stumbled on to this website...(well, I'm unable to post as a new user but searching for "How To Fix Samsung Galaxy error while searching for network" should bring it up).
There, I found some really odd directions that solve network error issues. The only part of the instructions I was really able to carry out was take out the battery and simultaneously press the home and power buttons 10 times. I restarted my phone and miraculously was able to place a call for the first time in a year in Japan!
But then I no longer had any data. I figured it had to do with the APN settings being wiped in the strange reset I just tried. But when I went into Settings>More Networks>Mobile Networks there was no longer an Access Point Names option in the menu. There is no longer a "Network Mode" option either. I used to have that set to LTE/WCDMA/GSM but now I only see a System Select option that simply lets me change my CDMA roaming mode from Automatic to Home Only.
I tried searching everywhere for the missing Access Point Names menu to no avail (and almost attempted to try flashing CyanogenMod for the time hoping this would bring back the APN settings menu) but then I realized that I could do a search in the settings app. I searched APN and the option came right up (though it's frustrating that this now appears to be hidden). Using the following settings (copied below) from the AU by KDDI website I created a new APN profile. Now mobile date appears to be working just fine too!
So, now I just need to decide if I want to keep running Touchwiz in Jellybean or use my new found confidence to try rooting and custom roms...
I'm also kind of curious to see that the next phone bill comes in as expected and I'm not being charged for a bunch of crazy usage! Also, any suggestions to help explain how I got into this problem in the first place, or how to clean up any loose ends would be appreciated.

No data after having WiFi enabled for a while

Hello,
I've had this issue across more than 1 device and more than 1 carrier.
Here's what happens:
I enable WiFi, and for a while everything works as expected. I can send and receive MMS messages. I can disable WiFi and go back to my 4G connection.
The problem is, after an unknown amount of time, the phone drops the 4G connection in the background. I only know when I can't receive/send MMS messages anymore. At that point, if I disable WiFI there's no 4G data connection, and I have to turn Airplane mode off and turn it back on.
This is really annoying. It happened to me using Sprint and a Galaxy S4 (both stock and custom ROMs) and it's happening to me with a Galaxy S5 from MetroPCS. (I've used the stock Metro ROMs, Stock T-mobile ROMs, and Custom T-mobile ROMs).
Right now I'm using a Stock T-mobile ROM with the latest firmware, carrier is MetroPCS.
What can I do so this doesn't happen? It's really frustrating.
Thank you for your time.

Disabled "Smart Network Switch" in WiFi Settings?

Disabled "Smart Network Switch" in WiFi Settings?

Hello.
That's already disabled.
Should I enable it?

I tried with "smart network switch" enabled and disabled and problem still happened.

My S5 G900F Android 5.00 (Smart Network Switch disabled, Power Save disabled) on EE UK has had this problem for 9 months after phone upgraded itself to Lollipop (EE win the accolade to being the SLOWEST ON THE PLANET to provide Android updates.....). Since Jan 3, my wife's G901, a couple of weeks after it upgraded from 5.0 to 5.02, has developed the same problem. Neither phone has ever been rooted or other.
I have fruitlessly searched everywhere for a solution without success. EE Customer Services Tier 2 & Samsung's own service centre have failed to fix it. EE & Samsung blame each other for 5.1 or 5.1.1 not being available for download. Neither is prepared to resolve the issue despite hours on the phone. Have tried Safe Mode, Factory Reset, clearing everything, reloading APNs & Samsung even reloaded Android. All a waste of time: Many many days of it!
After approx half an hour connected to Wi-Fi, only way to get the mobile data to connect, is either reboot, enter & exit Air-plane mode or flip the 4G > 3G > 4G connection under More Networks. Have tested the fault in different cell areas countries and continents; fault is same everywhere.
It seems there are quite a few sufferers of this problem.

Samsung S5 keeps losing data connection
I have the same problem. My new Samsung phone loses the data connection (even though data is turned on) and I can only re-connect by restarting the phone. The first EE shop I took it to couldn't help at all. The second gave me a new SIM - that didn't work. Then I tried online support and after 3.5 hours of my life, in which I was passed on from one person to another, they completed a factory re-set - which didn't work (and additionally lost all the personalisation of my screen and some of my contacts). So I now have a not-very-smart phone which I have to re-start every time I want to use data. This is a business contract and the phone is less than two months old, but I'm not getting any effective support from EE. Android version is 5.0.2

me too, since last update. and app 'phono' shows "mobile data off" not got a time on it, but when i leave wifi coverage, it wont reconnect to cell data 2g/3g/4g. flightmode toggle to restore.

Abandon hope if you have this intermittent mobile data problem!
...at least until there is a software update, though I have no idea if that will help.
I have now tried a new sim card, a factory reset, and a replacement phone - which was provided only because I'm a business customer and I found a sympathetic member of staff. *By the way, I was told that if you are personal customer they won't consider replacing your phone if it is more than a month old - even if you started complaining about the phone as soon as you got it, the chances are a month will have elapsed by the time they put you through the hoops of a new sim, reset etc - and then it is too late to insist on a replacement phone.
In any case the replacement phone didn't resolve the issue so I have reached* a dead end. My phone fails to connect to data after having been connected to wifi - you have to do it manually each time you move away from a wifi connnection. At first I was doing it by restarting the phone, but am now following the advice of someone else who has the same problem and am going into flight mode and out again. *
This is not satisfactory, and it seems from reading forums that EE are to blame for the problem rather than Samsung, but I'm not 100% sure about that.*

Possible solution that works, for me, at the moment!
Having suffered this issue of my S5 (SM-G901F) not connecting to mobile data after being on Wi-Fi for a while unless switching airplane mode on/off for a few weeks; although it has probably been happening since the update I received late December; I have tried all of the turn this switch off, factory resets (x2), etc, etc, etc. and Googled the issue without success.
I have found this thread interesting, and I even tried calling EE support only to be told "you have tried everything that we would tell you to do" and "it wouldn't be a sim card, or handset issue, sounds like software". The reply was basically that like-it or lump it until the 5.1 update is released "by Samsung not EE because EE do not release Android updates". [Perhaps EE don't release the updates, but the stock rom is tested by them and their bloatware added before they eventually release it!!!]
Following my last reset I tried selectively re-installing the apps I used incase that was causing the issue. No Luck!
One last thing I tried was to look at every system 'thing' that I could find which used/switched any part of the mobile/mobile data/wifi - in addition to the settings I had already tried (all of which were mentioned in this thread previously). One thing I could not find not mentioned here, or anywhere, was the VoWi-Fi call on/off which I had always set to on as I do not live in a great reception area. Calling over Wi-Fi is great when you don't have a strong mobile signal.
Having 'played' with this setting for the last 24 hours I have found that the VoWi-Fi on/off appears to be a possible cure - for me anyway.:fingers-crossed:
When VoWi-Fi was set to off and leaving the phone connected to Wi-Fi overnight, the S5 immediately switched to mobile data this morning when I turned the Wi-Fi off . It continued to switch between Wi-Fi and mobile data all morning whilst out and about in and out of Wi-Fi connections - Woop Woop!!!
I then tried switching VoWi-Fi on (with Wi-Fi on and at home), leaving the phone for a number of hours, only to find that when I turned Wi-Fi off the phone refused to connect to mobile data even with a 'decent' mobile signal. The only way to get it to connect was to go back to switching Airplane mode on/off.
Switched VoWi-Fi off again, left Wi-Fi connected, left the phone for a couple of hours, etc. and hey-presto immediately switched to mobile data when I turned the Wi-Fi off. [Dances around the room because he's got the S5 automatically switching to mobile data again. Even though I'm at home with a great fibre internet and strong Wi-Fi connection!!!]
I do not know if this could be a solution for the others who are suffering from this issue, but it appears to be a solution for me at the moment. I thought I would share as your previous posts have helped me and you all seem to be pulling your hair out; like I have been; trying to find a solution.
Try it, it may work, but don't shoot me if it doesn't!

It's encouraging to know that I'm not crazy. I've had this issue across two devices and carries.
John,
Thank for your suggestion about WiFi calling. Unfortunately, I always have it off! I never used it, so maybe I should try turning it on? We'll see lol.
At this point, I think this is going to be my last Galaxy line phone.

Is it wi-fi calling that's causing the problem?
I have wondered if there is a link with wi-fi calling, but haven't tested it properly. I signed up with ee and bought the Galaxy phone specifically so that I could use wifi calling, as the town where I live (in the Scottish Borders) doesn't get a mobile signal strong to work reliably indoors from any of the networks. I'll try turning off wi-fi calling to see if that sorts the data thing (though I see that for one person above it did not). That would mean I wouldn't get calls or texts when I'm at home so it would not be a permanent solution for me. But in fact the wi-fi calling is not reliable anyway....

Brian,
You never know the way things are going with this issue; given that nobody seems to be able to pinpoint the fault; turning it on may just sort it!!!

still no change and its a pita.....
