[Q] Mobile network data connection drops. Why? - Galaxy S6 Edge Q&A, Help & Troubleshooting

I have a problem with my Galaxy s6 Edge.
When browsing the web with only mobile data turned on, wether using edge/3g/lte, the mobile loses connection .
I still have connection visible in the status bar, but wepages stop recieving data and it just stays hanging, with the loading bar at the same place. It can be fine for 3-4 minutes and then start to act up again.
One sollution is to toggle data connection on/off, then it will work again, but only for a couple of minutes. My phone is unrooted. I have tried factory reset. I have tried using the different settings in mobile data; just gsm7just wcdma and wcdma/gsm- automatic etc. The signal strenght seem to be about 75-77dbma.
Do anyone have the same problem, know of a cause for this, or have possible a sollution? Please share

I've had a similar issue a few times now. No discernable cause. Solved by airplane mode toggle.

Yes, I will try that, but think thats about the same effect as toogling data. It helps, but the problem is still there. I sent an mail to Samsung about this issue. Hope it is software related and can be fixed. Its frustrating cause I`m reliant on stable data connection. When logging in again, the webpage has changed and i`ve lost my opportunity.

I have the same issue, and connection drop even if u you are in thetering mode(wifi/usb)
I got new mobile (replaced from vendor) and the new one have similar issue.
I try on lte/wcdma - only wcdma, with one apn and so on.... nothing to do problem is still there...

Sorry to hear that! Its a shame paying this much money and find out about these problems. This phone replaced my s4 because of the "sim card not detected-restart" error on the s4. First Samsung denied the issue. When they admitted it, I had already opened it up and exchanged the sim card reader, and lost warranty. That was not the fix.
Hope the issue will be fixed with updates. Lesson learned- Dont buy first batch of mobiles. Wait for prices to go down, and a more mature hardware.

I have the exact same issue on my s6. I can't figure out why it happens. It appears and disappears for no obvious reason. I wouldn't mind waiting for a software update to solve the problem but I can't stop wondering if I have a defective unit.

I' starting to wonder if there are network changes on the phobecausing this. The signal keeps going from H to H+. And maybe the adapter has to reset before it can download again. Just a hunch, but I have noe knowledge about what's happening.
But, if this was a widespread problem, I think more people would come forward saying they have this issue. If they don't have it, then maybe we got bad lemons, and we have too keep exchanging til we find one that works.

Its an software problem ( i guess of managing "swap" between h h+ and LTE. after 7 day of test i got the mobile replaced from mediaworld, and the new one have the same issue.
Im from italy with Vodafone, maybe all of us are vodafone.
can be interesting discover from where we are and our mobile company.

I'm using "Telenor" here in Norway. They have a 1 month deal with Samsung to be the only supplier of the edge. Tried to get internet/mms setup sent from them, but it said this wasn't available for this phone. But going to their guide, it seems everything I set up as it should.

I tried switching on the data roaming. That seems to solve the issue so far. I haven't had to switch the data on and off for more than 24 hours now. Before this I had to do it multiple times every day. I guess it's safe to say that the problem came from the software side. Let's hope that fix it in the next update. I'm using international version, though.

I just turned on the data roaming, but still on the same service. Now I can't really tell if that really did the trick. I got new firmware update just the day before yesterday and now the network drop is gone. If you haven't got any update yet maybe you just gotta wait. It's eventually fixed.

I have the same problem with a Samsung S6, AOE3. I want to return or change the phone, but I don't know if this is a software or a hardware problem....and to have the same problem with the next phone

I've got the same issue. Only airplane mode on and off helped me. But I've to do it many times during the day. I wrote a letter to Samsung and waiting their response.
Just read about roaming "on" as one of the users mentioned here, still testing.
PS I'm from Russia (on local forum many people has this problem). Hope this is software problem.

Same problem about my s6 edge mobile data connection
Still dont know what happen . I already have note series but there's nothing like this one. this make browsing much harder coz data stuck and keep hanging bout 1-2 minutes. Please make it fix ASAP . I love my s6edge

I am from Canada i have same issue plus my phone does not even have lte/gsm/wcdma option but still when i go on the *#2263# menu and put my phone to lte/wcdma it looses connection in like 5 minutes.
but still if i am connected to the internet same issue connection stops and it starts woking after a minute or so but really really frustating specially with a price tag on this phone.

Keep losing data connection.

I have an unlocked unrooted S3 on Vodafone UK. This issue has been happening for the last few days whereby i have full 3G/H+ connection, but absolutely no data is working. No email, no websites loading, no whatsapp, nothing. The issue goes away as soon as I restart my phone, but then it comes back after a few hours.
Has anyone experienced this, and if so, how have you fixed it?
Go back to your network/phone provider .
Or flash different modem .
jje
I am having this issue too. I may be wrong, but i realise this happens if i turn off my Wifi, the 3G will not want to connect to the 3G network.. Anyone else having such problem?
By the way mine is International version (Location: Singapore)
I'm having a similar problem where I have a good 3G/H/H+ connection but data seems to drop intermittently across all applications - I get the same sort of error message in browsers/facebook/twitter that you receive when you have no signal.
Anyone have anything similar and know of any fix?
I am not having such issue so far. I been updating my SGS3 using over-the-air update. I guess the MODEM has been updated as well.
Go to market and download "fast dormancy"(by gorkhanmoral) then disable it and reboot.
Check if your speed has improved,if it got worse then enable it again.
U need ROOT to use this tool.
I it didn't help, then flash a different modem
This is good modem
Cwm flashable

have you got any battery saving app like juice defender installed in your phone?
Is mobile data working at all? or is it constantly "uploading" but never "downloading" (up arrow lights but not down).
If what I just described is your issue then this is a network issue relating to android in general.
Basically your phone will be connected to two radio towers and gets confused as to which one it should use, rebooting or flight mode may help force it onto one tower or you may have to speak to your carriers "high network technical team" or whatever they are called for you to get them to force it onto one tower.
I had this issue on the HTC hero (a long time ago now) and it took 9 months for Orange UK to work out what was going on.

Congrats. Orange Luxembourg (my gf's network provider) still hasn't got a clue.. But they seem rather clueless about everything except writing invoices.
Flashing an Asian modem on her S2 made the issue far less prominent since they seem not to get confused by antenna ping-pong. (Tango Luxembourg, my carrier, has this issue too in the main city)

HELP! no signal

Hello
I got my xperia z2 D6503 2 days ago brand new sealed. I inserted my Net10 sim and it worked like 1 day and than I noticed that there was signal issue first I thought it was because of area than I found out it was phones fault since same sim card worked perfectly on my old xperia z and also on xperia z2 Tab and on my brothers galaxy s4. strange thing is it shows low signal only when LTE is on and I can send and receive text messages but I can't make calls. as soon as I turn off LTE it looses signal and no text or call go through.
I tried factory reset, 2 different sim cards, even bought new sim card, numerous restarts and nothing helps. searched web for this issue and nothing at all.
so anyone else had this experienced? any solutions?
thanks

Same issue with my z2... only when I hold it a certain way... I'm on Bell mobility in Canada and got the phone a few days ago.
I've been experiencing the same issue ever and I've had my phone over a month, I'm on EE in the uk running the .55 firmware. My phone is currently in repair to fix this problem so I'll get back to see if it can be fixed
Sony has no solution in USA and can't repair so I returned for exchange to seller. I though it was only me so looks like gonna be big issue

Hey, so did the exchange solve the problem for you? I am using NET10 as well and while I do get signal on all networks (2G. 3G, etc..) I notice that it isn't as good as almost any other phone I've had. I live in an area that has poor signal and places that I get 1-2 bars on other phones I get 0-1 on this phone, though when I'm in upper town where signal is great I get about the same as others do. I'm just not sure if my phone is defective or this is just how it is. I really don't want to wait to exchange plus the seller seems reluctant to do so..
I had to fix my APN (wireless &networks -> mobile data).
I Google the correct settings for my carrier(ATT/USA), and saved the updates and it worked IMMEDIATELY.
it's been solid since ever since. Note there are differences for the 3g VS LTE versions. Make sure you enter the right settings.
Good luck!

I did entered correct APN's as I mentioned it was working great for almost day and Than suddenly stopped working so if I had entered wrong APN's it wouldn't worked first time I powered it on. plus same sim card worked well on other LTE phone while was not working on my new Z2, so it was not APN issue.
Try rebooting 3-4 times and then wait. This should solve the problem.
Check the baseband version online and on your phone.
There is also a firmware update but you have to cable your phone to a computer and let it install the Sony software on the PC/MAC ... Mine updated yesterday...
Worth a shot if you haven't done so already.

Thanks man, it seems that's just how the phone is, maybe I can stop worrying so much about that now, especially since this Z2 I have has no defects that are so plentiful on other user's phones.
And like I said, it's not such a big deal when I'm in places with adequate coverage so it's tolerable. I updated to .402 yesterday and there isn't any change with signal but I'm holding out for more updates that can help out with coverage. I'm thinking once the Z2 is released in some way in the US (carrier or Sony store) that there will be an update then that may help us out.
I'm probably the last person to be offering advice in this forum, however, just a couple days ago I noticed I had no data connectivity at all. Calls and texting still worked, but no cellular data. All my APN setting were correct and even though airplane mode was not selected, turning it off and on again got my data connection back. Just something stumbled upon and I have no idea if it applies to anyone elses issue here. Just thought I'd toss it out there in case it helps just one person.

Solve which problem? The one i posted in very first post or the weak signal on my replacement? I did more than 5 reboots to solve first proble but nope.
Now this very weak signal worries me it loosed signal at places where my old Z was great. Hope this phone doesn't end up super problematic
Sent from my SGP521
Sony Service will service/replace the set, if needed. So please do check in there.
phone is amazing everything works smooth, but weak signal is getting on my nerves! looses signal very often and data gets really slow because of low signal even when LTE is available. I live in brooklyn ny and my xperia Z didn't have this issue at all. hopefully this could be fixed soon by software update.
Drop down quick settings from home and ensure LTE is ticked on.

Same problem
My sisters got the same problem,

Been on the phone for over 2 weeks !!!
They wont solve the problem what so ever !
One tech team even said "buy a new phone" !! such great customer service !!
They are wanting £150 for it so it can be "fixed"..... also wanting £40 for the month contract despite not having the phone !!!
I understand who you feel... they are no use what so ever and rude...

[Q] Samsung Galaxy S5 losing network connectivity

My wife and I both have brand new Galaxy S5s, and we both intermittently experience this problem. One of us will send a text message to the other, the text will show as being sent, but the other person doesn't receive it. If the person set to receive the message reboots their phone, the message comes through (as well as any other "pending" messages), and normal phone use continues for a few days until this issue returns. Rebooting seems to always fix the issue temporarily.
This of course is not limited to just communication between our phones, but I was using that as an example. Often times, I'll reboot my phone, and realize I have 3 new text messages, and 2 voicemails from yesterday. Very frustrating.
Phone calls are also affected. When these symptoms are present, phone calls cannot be placed or received until the phone is rebooted. Incoming calls go directly to voicemail.
The worst part of it is, there is no easy way to tell our phones are not connected to the network. The reception status shows good connectivity. Most of the time we're connected to wifi, so email and browsing the internet still work.
I'm just wondering if other people are experiencing this, or have any suggestions of some things we can try. Thanks for the help.

Samsung just rolled out a new update for T-Mobile S5 variant. This update should fix the issues you're having. Here is the link to it: http://www.sammobile.com/firmwares/3/?download=29848

Well, that was very timely. I'm glad they released a fix the same day I decided to ask for help. I appreciate the link, and I'll install it and see how it works out. Cheers.
The update killed a lot of people's data speeds. I made a ticket with t-mobile techs. I suggest anyone else with bad data speeds after the new update do the same.

From what I know T-Mobile doesn't care if your phone is rooted because you're not doing any warranty service. If that was the case they will probably tell you that its voided.. I have seen a few that root their own phones at their job so I doubt it'll be a problem. But I guess every T-Mobile store isn't the same..

Yes this is the exact problem I had with last GS5. Tmobile replaced it and I still have this problem with the new GS5. The tried to tell me it was just how the old GS5 settings were set. They had me do Factory reset many times, it never helped. Now with the replacement GS5 the exact same problem. Like you everything looks great on the display. I would just get calls on my home line wanting to know why I never answer my mobile phone. The only thing that helps me is a restart but it is only temporary. Do you know if they have released a fix for this problem?

Since upgrading the latest firmware, we have not experienced the problems again. We've been having good service since then. I would definitely suggest you get the latest firmware.

The only thing it seems the tmobile employees know how to do is a factory reset .. That is their solution for about everything . Like the other guy said they dont handle warranty . That is for your samsung warranty when knox is tripped . If you have handset protection nothing voids it from what i have seen . I think tmobile would rather replace a rooted phone than one with a cracked screen .

If you put that modem together can you link me it ? Could come in handy in the future. Thanks
I notice the problem occurs when switching to lte from 4 auto mode. Seems lte is giving these problems. Switch to wcdma only mode and the problem will be gone. No lte tho... I will update to latest fw and see if it solves my problem

I have a brand new S5 as well and experience exactly the same problems described, and my friends also have Samsung phones and tablets that give the same network connectivity problem.

Internet settings for Life Mobile (EE) in UK

Hello there,
I have been using Tesco Mobile with my Redmi Note 2 for a couple of months now and have had no problem. I decided to switch networks to a VPN called Life Mobile. They use EE's network in the UK. Since putting in the sim card today I have not been able to connect to the mobile network. I am wondering if anyone else on this network with this phone could help? I have called Life Mobile's helpline and all they wanted to do was run me through EE's apn settings. I had already used their app and also searched elsewhere on the web to find a few different APN settings but none of them worked.
One thing I'm wondering about if whether or not the custom ROM/firmware (MUI 7 I believe) that the phone shipped with (bought online from China by the way) is having anything to do with the internet problems. I get the feeling the customer service for Life Mobile were fobbing me off when they said that maybe my phone just isn't compatible with their network. Phone calls and texts work fine by the way.
Does anything think flashing the phone to the standard android ROM that's available would have any affect on the internet settings. I'm no mobile expert, and with the phone not being on general sale in the UK yet as far as I know, I would appreciate your help to get this internet/mobile data settings issues sorted, as I do use my phone for work.
Thanks in advance for comments and help.
I definitely know that the ROM that came with my phone from Gearbest was the worst piece of software that I have ever used in my life... ever. Check your MIUI build number and see if it's something like 5.xx.xx or 7.xx.xx. If it's something more like 77.55.66, then you have a knock-off and it may be eating your battery, performance, and experience (the original ROM Gearbest flashed on my phone had so much bloatware that the antivirus warned me about one of the programs every ten minutes, and heated up significantly on the home screen). If you have an unofficial ROM, try flashing a developer weekly or stable.
Hi all.
Well, would you believe it, I have spent a large part of the day trying to figure this out and finally I've done it. I'm not quite sure how but I've done it. I'll explain briefly to help anyone else who may be facing the same problem. It seems that changing the network preference setting within the sim settings from LTE to 3G did the trick. Life Mobile does not support 4G as far as I'm aware. That's no problem for me as I'm perfectly happy using 3G when necessary. After doing that and fiddling with the network settings, eventually reverting back to the automatic selection of the network as EE and using the APN default settings as given by the sim when it first was entered into the phone, things suddenly start to kick into life and we had INTERNET!
Thanks for your help in resolving this, and happy New Year to everyone.
same problem
Hi mate,
I'm having the same issue now on life mobile, I've checked all the settings are right but still not picking up mobile data. Any suggestions? Constantly restarting it hoping something will be different but nothing so far.
Cheers

Driving me crazy as well (on a Lenovo K3 Note). Still have the Tesco SIM in there. Was going to port the number on Monday, but might get them to take the damn thing back!
Tried all the suggestions above, but nothing working. Tried both SIM slots with and without the other SIM, but nothing. Grrrrr....

Well, they sent me a new SIM card and I had all the same problems until I switched on "data roaming" and it now works fine (it didn't do anything with the last SIM though, when I tried it in another phone, I had to have date roaming on in order to even get a regular signal- data still did not work). I have seen transient "R" occurring when the SIM was activated/deactivated so had suspected this as a problem.

Elephone S8 Weird issue with network

Hey all,
I am hoping somebody can guide me in regards to an issue I am facing.
I was working on my car a few days back and left the Elephone S8 on the car seat not realizing that it was being hit directly by the sun. After I was done, I picked up the phone and it was very very hot. I then went inside and let the phone cool off.
Since the above, I notice that I struggle to pick up reception. I have tried different firmware, replaced sim cards, everything. It seems to only be affecting certain MHZ bands as 4G LTE work, 3G works fine, and 2G works find but not always.
I have a feeling the 2G is having issues but maybe only certain bands. I do not think it is software related but have no idea where to even start on the hardware side. I first want to try scan for towers and see which bands they use and try see which one could be giving the issue. I don't expect it to just be a lose connector as the phone has not been dropped and I have only been using it for 2 weeks. If I do send it back under warranty for repairs, they will never pick up this issue.
Elephone S8 loss of network issue
Hi.
I think is a hardware issue as the same thing happened to me after 3 weeks perfect use.
I think has nothing to do with the sun as for me happened on a snowy Sunday 10th of December in London.
I suddenly noticed that when sending email the sending would start fast and after a 2-3 seconds the network will drop to 3G and stay like that for long time until the mail app stops sending process and the phone goes back to LTE 4G.
Also when dialling a number the phone will drop from 4G to 3G and than loose the connection straight away.
When indoors the phone would have trouble registering to network for ages without success.
I picked up 4 different pay as you go cards to make shure that is not my network but still no success.
All documented in the support ticket to GB and yesterday have send it back for a refund.
I really like the phone but i am reluctant to buy another if the issue persist so will wait and see.
Hope some more comments will follow to highlight the problem and influence a solution to this.
Cheers
I have the same issue - my wireless connection inside my home keeps dropping and connecting off and on again and again - I have two routers and maybe as I move from room to room it tries to connect to the closest router or something like that - not sure if there is a way to fix it without doing something in the routers.

Same problem here
My network problems are a little different. I don't have problems connecting to different wifi networks (home and work) but the phone does not activate mobile data when leaving a wifi network. I always have to restart the phone when I want to use mobile data (3G).
Kind of the same problem. Have my S8 for about a month. First it has a wifi network. When I leave the place where it is connected to wifi, it goes to 4G. But when I come back to a place with WIFI, the phone does not find any WIFI network. I have to reboot the phone. Soft reboot(a little faster) will also do/work.
Are you guys on the stock ROM?
Were you guys able to resolve your issues

I have the same problems with stock rom and eragon rom. I don't have a solution but I'm still hoping for a new update.
For now I found out that turning flight mode on and off again helps to switch between wifi and mobile data, so it is not necessary to reboot the phone every time.
I can confirm as well that Eragon won't resolve 3G / 4G network issues.
I'm using my S8 for a week now with only one problem, call related.
No wifi problems but after one day of usage I couldn't use mobile data anymore I almost re-flashed my phone (unlocked bootloader, rooted and using Xposed). Turned out my provider f*cked things up. Probably because Elephone is a not known brand here. It took me some time to convince the agent on the phone that I do not own a Samsung S8 lol.
Problem was solved at the providers end.

This information sounds interesting. How did you manage to 'convince' the providers agent that it is not Samsung? And what did you tell it instead?
Steve the issue you have is different. Your issue won't be resolved that way.
You would need an app that switches to 3G/4G if WiFi is not connected.
Happy too soon. After one day with mobile data it's gone again. There's a cross in the lower right corner of the mobile data icon in the status bar. I'll be calling my provider again tomorrow morning.

I'm not sure if the fact that I own a brand that is unknown here causes the mobile data problems. The problems I'm running into atm are
- mobile data problems, 4G is connected, but no internet
- fingerprint scanner doesn't work with my banking app
- backlight bleed in the middle of my screen
- after 3 out of 4 calls, phone freezes for about 30 seconds
- rattle in fingerprint scanner
I guess I'm about to find out how good the return policy at Banggood is ?
I highly recommend that you return the phone now.
There are so many issues with the phone that it's just not worth the time.
Hi guys, I just got the phone, but mobile data is not working. Am I missing something?
Can you attach a screenshot

Does your sim card work in another phone? If so, are the apn settings the same?
I managed to resolve the issue.
I'm trying to figure what went wrong at start. When I got a phone I inserted both SIM cards like this:
SIM 1 - my business phone number - provider 1
SIM 2 - my personal phone number - provider 2
I wanted to use data only on my personal phone number, so I disabled data on business number. What happened is my business SIM downloaded APN info on first boot (i assume), and then my personal SIM used this APN (which was incorrect).
To resolve issue I first inserted my personal SIM to slot 1 alone and booted. Then I changed APN profile to match my old phone's, turned off phone and inserted my business SIM to slot 2 and booted.
Now data works fine. Obviously there was APN issue but how come that phone didn't get correct APN settings per SIM?
Thanks for support!
