No data after having WiFi enabled for a while - Galaxy S 5 Q&A, Help & Troubleshooting

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?

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!!!

[Q] Losing data connection when switching between Wi-Fi and Cellular Data

Hi All,
Long time follower, first time poster..
I have a very annoying issue with my Nexus 4(4.2.1 and rooted on Tmob).
I use wi-fi connection at home and work and in-between I switch to HSPA or should I say, I was able to..
Lately I have been seeing that If I leave the Wi-Fi area, the phone doesn't switch to cellular data and the connection gets lost.
Switching to airplane mode and back brings it back most of the time but it's really annoying having to do so..
I did find an issue #40514 on the google android code page( code.google.com/p/android/issues/detail?id=40514)
Tried the suggested work arounds like "Auto Network" setting and it didn't seem to help..also have tmob in the APN settings. Still the only thing that works for me is toggling the airplane mode.
This happened to me once on my previous Gnex but with N4, it started to happen all the time.
Does anyone have a better solution to this issue?
Thanks
Oz
even I face the same issue with this new Paranoid 4.1.2 ROM for Atrix 2. I've noticed only one ROM gave me consistent data 24/7, it was from same dev altered his NUMA B2.
But other than that, this has been a repeating problem in all ROMS. Data stays on for hours without issue but suddenly drops and never comes up, other than air plane toggle. Somebody mentioned it is with the network and trust me it is not..
but I'm also eagerly waiting for a solution

Yea, at first I thought it has something to do with rooting but apparently it is happening with non-rooted phones as well..Google needs to address this issue..

Just throwing in my two cents; I starred the threads that I *think* are related on the google tracker. My experience is like this:
I start up Sirius on my phone before leaving home (On wifi)
Driving to the end of my development and then lose WIFI which in turn turns my 3g/4g gray for about a half mile
Picks 3g/4g back up eventually
As I'm driving to work if I end up picking up any open WIFI spots that have a login, once that happens I lose 3g/4g again then have to either wait till that access point is out of range or just turn off my WIFI before data will pick up again
It's pretty annoying; probably going to have to create a tasker profile to turn off wifi when leaving the house and back on when I get home.
Same problem on an LG F6 Optimus
I just got a brand new LG Optimus F6 and I'm noticing this same issue. The phone is stock and runs 4.1.2
Anyone found a solution?
the issue continue in n4 with 4.4?

"Ready to connect when network quality improves"

Hi guys,
Getting this message upon connevting to virtually every wireless network sinse rootibg my phone, is there a root tweak to disable betwork quality checking ? On a G900F
Thanks
Anyone?
You should be able to turn off smart network switching under wifi settings that will solve it.
Nice one thank you! I will see what happens!
turning off smart networks helps, but if the wifi signal is too poor it will not connect anyway

ready to connect when network quality improves
We have two Galaxy 5s in our home (AT&T and T-Mobile). Both just started getting this message last night. "ready to connect when network quality improves"
Its multiple access points, multiple networks. Eating battery like crazy. Dropping and reestablishing connections to WiFi every 15 to 60 seconds.
Pain in the @zz
Turn off "smart network switch"
I also started getting "ready to connect when network quality improves" messages constantly as the network connected and disconnected. Turning off the "smart network switch" option fixed the problem. I also leave the annoying Samsung Connections Optimizer turned off.
Smart Network Switch Off?
I just got my S5 about 6 weeks ago. I have had NO issues until this week. A few days ago, even though wifi notifications were turned OFF - I kept getting this "connected to network name" message on the bottom of my phone. When I went into wifi settings this morning, I noticed it would switch from connected (very strong signal strength) to "waiting for signal quality to improve". It constantly goes back and forth - 5 seconds or so on each. This is not an issue on any other device connected to the wifi router at my home and I just tried it at work - happens here too.
I checked to make sure wifi notifications were off - they were - but the pop up still appears over and over. I think that's another issue separate from this because if notifications are off you should not be getting any!
I have done as suggested here and turned off the smart network switch, however, does that now mean that I will be switched back and forth every 5 seconds from data to wifi? That defeats the purpose of connecting to wifi to save on monthly data plan charges.
AFTER noticing this problem this morning, I went to see if there were any software updates - there were (Lollipop). I did download that, but no change.
How does turning this off affect where my phone pulls from? Uses data or wifi?
Thanks for any help!

+1 with exact same timelines/symptoms and upgraded to Lollipop and no diff too.
I started getting this message on my S5 last night! The connection will hold for about 10-15 seconds before reverting to LTE.
Tried resetting router settings, playing with different wireless settings - changing channel width and turning the visibility on and off.
Then "forgot" the network and readded it again.
It seems to be holding a stable connection without it dropping and was able to download a few items from the play store without dropping.
Will update if it changes.
Same here S5 900F

Me too - I've been searching for weeks to figure this out - tried every known fix .... nothing has helped. I've even reset/changed/updated my wifi settings on my router. Nothing has helped. My S5 is the only one that has this problem. Other phones in the house have no problem - S4 and others.... I just don't know whats going on. I maxed my data avoiding this issue - but I really need a fix for it.

This problem was driving me insane......I had it and managed to fix it (hopefully been going ok for three days now) I have a samsung Galaxy S5 on EE.....I backed everythingh up and did a factory data reset. Hope this helps.
I have a Galaxy S6 and have the exact same issue. I have called Samsung, my carrier (US Cellular), and tried a local place to get it fixed, but no one has ever heard of this issue. Amazon Photos was hogging a lot of bandwidth and backing up on wifi only so I stopped using that. Still not much of an effect. Using FB or a video is almost impossible because they won't load or refresh. I've tried all of the suggestions, but don't see a final fix. Can anyone help? This is my second S6 with the issue.

Help getting XT1575 working again while in Japan. Please!

I'm in Japan for a couple of weeks for work and signed up for the Japan pack that Sprint offers. I spent almost an entire week working with Sprint support ( ) trying to get data roaming working properly on the phone without much luck (voice and text worked great), but yesterday I lost all connectivity but wifi. Figuring I must have changed something I shouldn't have, I saved everything I could and did a hard reset on the phone.
It still won't connect to any networks. I've re-downloaded PRL and device configs over wifi in the settings but it doesn't even attempt to connect to any wireless networks, or see any for that matter.
I have 2 guesses here but I'd like some kind of confirmation here before I take any action.
1: Maybe my radio firmware is corrupted somehow? I'm not exactly sure how to check it but it just doesn't seem to be doing much of anything. In the SIM status page it says searching for network, but I have no way to know if that's really the case.
2: Since the phone has a Sprint SIM, does it has to be on an actual Sprint network to initialize the networks? (Not Softbank's network here in Japan?) I spent over an hour on Google Voice with them last night trying to get an answer/help but got absolutely nowhere.
The phone is currently all stock but I have no problem unlocking and installing recoveries/software/roms if need be. Any ideas what I can do here or am I just stuck without communication until I get home next week?
Usually the best route is to get a local prepaid sim while traveling but honestly I have no idea what sprint offers for roaming in Japan. Check your plan and see if there is an add on needed.
I'm not alone!
Also THIS IS STILL AN ISSUE!
It worked fine for me last time I came to Japan, about a year ago. This time, I only have voice and text, no data. Right now I'm backing everything up to do a factory reset.
Did you ever find a solution to this?
I'm not sure if you've already done your factory reset, but if you're on Sprint, don't do a reset. The phone can't reactivate itself off of Sprint towers. You have to be in the US when you do the reset. I was stuck with WiFi only for most of my time there because I reset mine.
I never found a solution other than dropping Sprint when I got back to the states. Switched to Verizon and never looked back, though I'm not sure what I'm going to do for my next trip with their ridiculous international rates.
I actually got it working last night.
Factory reset and restore over wifi
Update device config over wifi -> handles activation
Update PRL over wifi 3 times
Now it works
Oh, I'm glad it worked. Is yours on Sprint?
Yes, but I may have spoken too soon. It worked for a few hours and now isn't getting back on data. I think it may be SIM related, since I saw a weird SIM error pop up and rebooted my phone, which led to the data working the first time
They must have redone their activation system since I had my issue in July. At that time there was no way for the phone to reactivate without being on Sprint's system.
As far as the data, that's the same thing I had happen and they were never able to solve the problem. It would work for a little while then stop for no reason. If you find a solution I'd love to hear it though.
I'm wondering if I can flash a different radio or something

Sim card disappears after 2-4 minutes when making calls with VoLTE enabled

My v20 drops all calls between 2 and 4 minutes in, and usually around the 3 minute mark. The call drops, signal goes to zero, and a moment later I get a toast message saying "Loading SIM card contacts..." and then I can immediately dial back in.
WiFi calling is disabled, though the setting being on or off doesn't seem to make a difference. I've cleaned the SIM card and added tape to the back to ensure good connectivity - no change. I also went to T-Mobile and they replaced my SIM on the spot but it immediately happened again in the store and in front of the clerk when we tried a call. They've suggested a warranty exchange.
One interesting thing I've found though is that disabling VoLTE calling fixes it entirely - it no longer drops calls, but of course there's no HD voice and I can't use band 12 and they're already cutting back on HSPA coverage.
Haven't found anything else useful via Google or XDA. Even with VoLTE enabled there are no data drops, VOIP calling via hangouts works fine. Anyone have any ideas short of a full exchange? Not rooted and while the LG backup app is pretty good, I really don't want to go through the day-long process of restoring everything if I can avoid it.
Hey there! I had the same issue, exchanged the phone for a new one, and STILL have the same isssue! Did you ever find another fix? This is so annoying and I cant believe a bigger deal isn't being made of it.
Something wrong with ur
operator

Been owning V20 for about 5 weeks now. The first 3 weeks were pleasant until I started seeing dropped calls. Disabling VoLTE did not help. Changing sim card wouldn't help either.
I'm having similar issues H915 Freedom Mobile.
Was roaming on AT&T in the US when I first did the update. And everything was fine till I was home and on Freedom.
When Wi-Fi calling is enabled. It makes no difference if mobile preferred or VoWIFI preferred is selected. It enables either way after reboot or turning Wi-Fi adapter off and on again.
Incomming calls frequently don't come through regardless of whether vo wifi is on or off. Texts same problem. And persists sometimes on cellular and sometimes on VoWifi.
Get SIM errors, signal drop constantly. And have tried everything I can think of to rectify the issues with zero success.
Anyone with Freedom having similar issues? Or any suggestions I might not have thought of that may be the the cause?

lost cellular data

So, when I woke up this morning I noticed my cell signal strength icon was one I haven't seen before. I tried rebooting and toggling airplane mode. I also verified that my sim is working in another device. I attached a screen cap with the icon.
Noticed something similar with mine. I had to turn wifi off, restart to get LTE data (verizon) then turn wifi back on. If restarting with wifi on the LTE data doesn't register.
that didnt work for me
update: had to factory reset, looks like verizon doesnt like that essential ph1 wont take all their bloatware, etc. might have to return the phone if this keeps up
My data connection has also become very erratic - and I've lost voice+data (VoLTE connectivity) wholly yesterday. Worked fine with the activated SIM from my HTC 10 from the 31st to yesterday.. Now, not at all, I've not been able to restore it since.
Really don't want to return it, as I really like the phone, but this has nexus 5x issues written all over it for long term use...
Hoping essential can get a certification and an agreement with Verizon before my return window is over (or at all)..
Pretty disappointed in Verizon here.
Sent from my PH-1 using XDA Labs
Same here, another issue is that essential shipped my phone and within a day i had an email from essential saying that verizon certification is still in progress. verizon will probably not certify it with their system unless essential lets them install their monitoring crap all over the phone.

The Nexus 6P didn't have the bloat and worked fine.
My PH-1 works fine including Enhanced 4G LTE Mode.
What do you have selected for network type?
I have the first one selected because that's the only one that includes the various CDMA protocols, EVDO and LTE.
I see the same connectivity that I had with my Nexus 6P.
i have global selected, as it covers everything the phone can connect to. i had the first one selected but it wouldnt show the lte+, just regular lte. i also have Enhanced 4g lte mode on. it just happened to lose service earlier today. if it does it again, ill probably return it after a visit to vzw

I have the same settings as you, I had functional "enhanced 4G LTE" for the first 4 days as well... That ended yesterday morning abruptly, and I'm not able to bring it back.. There's more happening here.. How long has your device been on the Verizon network? Only a hunch - in a few days you won't have "enhanced 4G LTE" either, even though it'll still be checked, and provisioned for it.

Cellular network is not available
After 7 days my phone won’t make calls I can only use data I’m on sprint and it was working fine until today I call sprint they had no answers at all I email essential no answer now I can only use WiFi calling while home and axx out at work
So, upon further digging I found a place to look at some more in-depth stuff relating to signal stuff. I did some fooling around and switched it from unknown to lte/cdma/umts auto (prl) and it seemed to work after a few moments of time. Though it seems have gone back to t he unknown state again but is working normally for me now, so maybe it was changing states and then a reboot?
How I got to this screen was by punching *#*#4636#*#* into the dialer, and went to phone info
I'm having a similar issue. I often lose my signal. I will have the full triangle/bars but no label of the signal(LTE+/LTE/3G/1x/etc....) and no cellular data at all.
The only way I can get it to return is to restart the device. Happens a few times a day, can't be 100% sure why, but it often appears to be when switching from WiFi -> Cellular only.
I have Verizon, I have had a Nexus 6 and then a Pixel XL for the past 3 years, never once had this issue.
I had constant disconnects and lost of service with my Tmo sim. Tried my Xfinity (VZW) sim and it was great until this morning. Complete lost of service. Airplaned mode on and off, connected to old school RTT 1x.... lol This phone's cellular just plain suck for a lot of us regardless of carrier. Not sure if we just have bad phones because apparently there are those who claim they have great service and connection.
I'm having this problem with Verizon. Seems like if I'm on wifi for a long period it only connects to 1x and putting in airplane mode and stuff won't get it to re-connect to to LTE. Only a reboot seems to fix the problem.

Necro post here but chiming in that I have the same problem with Verizon LTE. Happens when I'm moving long distances in car too. Suddenly just drops LTE and only a reboot will bring it back.

You might check out my post from the Oreo Beta thread... I was having some goofy signal issues early on which I've pretty much cleared up by doing what I mentioned here. Someone touched on it briefly earlier but only mentioned monkeying around with the settings, said nothing about picking up a new PRL.
I state this in that post too, but just in case: I offer this with no express intent of warranty, if you screw up your device, it's on you.

I just changed it from global to LTE/WCDMA and I got LTE back almost immediately. Was weird and global had been working for me for awhile now so not sure what happened in the past few days...

I set it to global as instructed in another post. The next time I drive a distance in the car I'll have to see if I have the same issue that only a reboot would fix again.
Thanks
I had the same issue and I resolved it a little differently than the previous posters. I turned on adb debugging and logged into adb shell and user-disabled com.redbend.app. This stops the Sprint oma-dm service from running. After doing this I no longer have the issue of my device not reinitializing lte after sleep or 3g.
I have essential on vzw but my only issue is my device won't connect to 4G. If I change network to LTE I get full 4G service but I'm unable to make phone calls. Went into vzw store and they told me you didn't get the phone from us so we cant help you. Day 14 fml
On Xfinity mobile, I had similar issues. Great LTE but sometimes calls just don't work at all. I mess with various settings and it'll work for a bit then so again. Gave up and ported over to Sprint for the free unlimited year which is still probably not worth it. Should've kept with Xfinity Mobile. Lol
