(SOLVED) Mobile data turns on and off unless Wi-FI is on - Samsung Galaxy S8+ Questions & Answers

EDIT: it was T-Mobile's signal, not my beloved device.

Hey guys. This popped up out of nowhere
My data disconnects, quickly reconnects, then disconnects again and again unless I turn on my wifi, then data seems to stick until I turn off wifi again.
https://youtu.be/GUzThuJy14E
I had adguard for a few weeks activated, but nothing changed recently.
It does it regardless of:
Smart network switch being on or off
Aggressive WiFi/cell hand over is on or off
Keep mobile data turned on is on or off
I cleared cache both through recovery and phone maintenance, and I also reset network settings to no avail.
I've never dropped the phone and this started randomly while plugged in. It was at 19% and I plugged it in and noticed it out of the blue.
I'm on a US unlocked (non-carrier) S8+, and SIM works fine with no issues in my Moto X Pure, so it's not the SIM.
Please help guys!

Okay, I popped the SIM into my Galaxy S4 for ****s and giggles, and it's also doing it there, but not on my Moto X. So I'm gonna have to have a chat with T-Mobile tomorrow. Don't get it, the SIM is fairly new, is it a Samsung thing?

But to affect my other Galaxy device and not my Motorola?
My S4 and Moto X are rooted, but not my S8 is not, yet it affects the S4 exactly the same when swapping the SIM in and out?

I was saying it affects my rooted S4, but not my rooted Moto X when I swapped my SIM into each phone.
But member Britchel says it was affecting them as well, and it was just T-Mobile, nothing to do with the phones themselves, so it's all solved now.

I know it's solved but, here http://bgr.com/2017/07/06/t-mobile-down-lte-not-working/

Awesome, thanks! ?
Going back and reading my posts, it sounds like English is my 5th language. Sorry guys, I noticed the issue right before I was going to go to sleep, so I was half awake at 3am trying to figure out WTF was going on.

[Q] Network Dropping

I just want to check in and see if any other Inspire owners are having this issue:
I have noticed that my phone occasionally drops the network connection and doesn't get it back right away. There are two different flavors of this issue that I have experienced:
1) I was walking my dogs today and the phone suddenly dropped it's connection to AT&T completely. After a few seconds, it reconnected and everything was fine. I was in an area with good coverage and the status bar showed no connection at all.
2) When home, I leave the Wifi on. Earlier today, when I tried to make a call, it simply wouldn't dial out. Then I tried to open a web page and nothing (after turning wifi off). I had to switch airplane mode on and back off to reset the connection. I also received several text messages at once, all of which had been sent hours before (as indicated by the time stamp on the message). It's almost like the phone has an issue swapping back and forth between the carrier connection and the wifi.
Is anyone else experiencing anything like this?
As an update, I noticed that when the wifi is on, there's a check mark under the H+ symbol (rather than the up/down arrows) and when I switch off Wifi, it doesn't go away. During this time, I have no cellular data. Switching airplane mode off and on doesn't seem to work. Sometimes it recovers on its own. Other times, I have to turn the wifi off and on several times.
This is annoying. It seems to be having issues doing the hand-off between Wifi and cellular data. This is really the only issue I have with the phone. Hope they roll out a fix soon.
I had the same problem. I thought it was because I had to add my own APN. (I could not switch my plan around because it was a work SIM). This caused SMS messages to not go out and an overall bad network experience on the phone. I have since returned the phone because I need a reliable network connection and the ability to send/receive SMS messages at all times. Once a fix is found I will be back. I liked the phone alot otherwise.
Are you by any chance using the SIM from another phone? I had the exact same issue yesterday and data did not work for me until I called AT&T and had them update IMEI number from Captivate to Inspire. Hope that helps.

Nope. I made it a point to have them activate it in the AT&T store with a new sim because I had read about people having issues when they transfer their SIM. I also had and iPhone 4 previously, so transferring wasn't really an option. I'm definitely on the right data plan, too.
I left the wifi off all night and it did it to me again today. The check mark shows up under the H and it loses all data connectivity. I'm not sure what is causing this, but I'd love to know if there's some kind of workaround. I have messed with a few options (like the data always on option) and haven't had any luck.

I was using a SIM from another phone. It is the SIM card from my Work phone and I can not change the plan. It does have unlimited text and internet I just cant change it to a 4G plan. I had added the APN that is floating around here and that worked except I was having the same problem as the OP.

Like I said, my issue was very much like yours and OP's and adding cutom APN made no difference until I called AT&T and had them update IMEI on my account. Presto, all problems went away instantly. I understand that it's not an option for you, sorry
have you tried creating a new apn? try creating one using these settings.

Just did this. Thought it might have resolved it at first, but it didn't. Basically, when I put the phone down for a while, it's like the data connection goes to sleep and doesn't wake up. When I turn the screen on, there's no mobile data. Sometimes, the dual arrows are visible under the "H", but only the up arrow is lit. Other times, the check mark (meaning no data) shows up under th "H" and stays there. Switching Airplane mode off and on will reset the connection.
I hate to say it, but the phone may have to go back. I love everything else about the phone, but this bug is too major to wait for an update or fix. What good is smartphone that doesn't get data reliably?
are you running the stock rom? i haven't been using that rom much so it may behave differently than the custom roms.
i don't think its a common bug. i would see if you can get a replacement phone.

Definitely stock rom. No rooting or anything. I didn't notice this on the first day I had the phone because it was on Wifi almost all the time. I turned wifi off to test it and the issue persists. I suppose I should try resetting the phone first, though I'm not looking forward to setting it back up again. After that, I'll take it into AT&T. I'd love to keep the phone. Can't believe no one else is having this issue.

yeah, resetting it up is a pain. sorry, and i hope you get it fixed.
Just to say it again. I had the exact same problem as the OP. Maybe we both had a flaky phone?
Okay, turns out there's an issue with the AT&T tower closest to my house. I found out from a rep at AT&T. I haven't left home much at all this weekend, so I had no standard for comparison. I just verified it by turning the wifi off on my iPad and using 3G data. It has the same issue.
Of course, I had already done a factory reset and gone to the AT&T device support center, but at least my phone is fine.
As a side note: I love that Android restores your apps now. I always thought WebOS was awesome for doing that and that was what frustrated me most about Android, with as often as I swap phones.
Wow... Wish this was my problem. I switched back to my Palm Pre+ and my data works fine.

So frustrated, about to return One X but seeking advice

All,
I have had the One X for just over a week now. Three times, I have had to hard reset the phone because it stops receiving / making calls, and data stops.
I tried searching the forums but it seems like issues are all over the board and couldn't really find something that was exactly my issue. If there is one, I apologize for the duplicate post.
Regardless, when the phone is in this state, it appears like everything is working. It shows I have great signal, the little 4G icon is there, indicating that everything is working.
Anyone else have this problem or could I possibly just have a bad unit? AT&T already swapped out the SIM card thinking that might fix it, but no luck.

I think you should swap out the phone as bad before returning it if that's the only issue you're having. mine seems flawless in that regard. I haven't missed or dropped a single call.

I don't recall ever having that problem. Mine was pretty random too, in fact it got so bad yesterday that I missed several important calls.
If I would restart the phone, I would get all my missed text messages and the voicemail (google voice) would tell me I have messages waiting..
Very frustrating.

I thought that might be my problem too, but where I could stand in one place and have the problem, restart the phone, and then not have the problem -- that leads me to believe there was something wrong with the phone.

My X started out ok, but these last couple of days I have NO signal anywhere. Also SMS/MMS is barely working. (and when it does, people are getting multiples) And its dropping pretty much every single call.
I just called my corp store, they have plenty in stock. I'm going to go exchange it. Should I ask for a new SIM also?
And my screen is perfect, here's hoping I get another good one...

However, AT&T's LTE phones are notorious for connection problems on non-LTE market. These LTE phones use a new APN called pta. I just had the same problem while traveling through PA yesterday. Lost data connections many times and had to reboot the phone at the end of the day to regain data connection of any kind.
So, it is AT&T's service and also the phone firmware that can't properly handle the fact that it can't receive any LTE signal in certain areas.

return it and get another phone, besides the One X, it's all hype anyway. The HTC vivid is a much more solid phone.
I had almost the same issue. My device was on wifi and would at random times just stop pulling data. Or at time just not make calls. I tried trouble shooting it but I was basically told since I didn't have it long I should get it replaced. I replaced it and the new device is perfect. I have not once had that issue again.

Who said I'm going to reture it. OneX, regardless all its problems is still way better than any alternatives AT&T have. There is no such thing as problem free Android phones. I've being many of them. They all have problems one way or another. Vivid with its ancient S3 CPU and SD screen just plain sucked. My SGS2 can kick its butt.
For me the form factor of One X, LTE speed, S4 processor and HD screen are the main things I pick One X over any other phones available on AT&T. These software bugs will be corrected overtime.
I just came back from my store. They had plenty in stock but said when that runs out, they have no idea when they will see anymore.
I have a brand new 1X, and a new SIM card. Hopefully this one works.
I stopped by a vzw store to look at the gnex and my hox side by side. I've decided to keep the HOX. Screen on the gnex was way too bright and I ran quadrant side by side on both phones. The hox blew the gnex out of the water.

Bought mine yesterday and this same issue happened to me today. Had full reception on 4G but could not send a text or place a call. Happened twice today, and I dont know if I want to return it ASAP or if its software related and may be fixed.
I had that problem 3 days after buying the phone. Data, calls, texts..tons of problems. Phone was unusable half the time. I went and exchanged it for another one. I am now at 6 days with the new phone. No problems. I hope it lasts.

Rogers HTC one x. Strange thing happened last night. Signals related

I got a new one x 2 days ago and its been working fine. However, my battery died last night and the phone turned off.
After plugging in the phone, the phone restarted but it would not connect to the network. I went in the settings and it said the network was disconnected. I tried changing bands from lte to gsm... nothing worked.
I restarted the phone a few times, still No signals.
I then did a factory reset and the signals came back.
I am not sure what happened. is this a software issue?
PS: I should add that this is a Rogers One X that I unlocked. I disabled all of the rogers apps
anyone?

Yes a lot of mobile network issues as well as dropped calls and freaky wi if. Im sure they are looking in to it. I exchanged mine for same reason. Hopefully the promised soon update will fix it. Normally restarts fix it. Sometimes it takes multiple restarts. More than one thread concerning these mobile data issues in general. I'm on the new Asian 1.88 just for those issues. Fingers crossed its fixed. Let u now in a few days at most.
So its software issue and not hardware right?

Nexus 5 - Dropping network

My S3 died last week so I purchased a Nexus 5 and I've had nothing but issues with it since.
In 6 days it has dropped network about 10 times and just displays 'Emergency calls only' until I reboot it. It seems to be completely random.
Twice it has done it whilst streaming over 4g from YouTube, but it has also just done it whilst dormant overnight. I woke up the other day to find 'Emergency Calls Only' despite it being fine when I went to sleep.
After searching google I can now see that this seems to be a common issue with Nexus 5.
I'm seriously considering taking it back and getting something else, although I'd love to keep it if it works properly. Does anyone know the cause of the issue or have any workarounds? As I use the phone for out of hours calls for work, I can't afford to have it drop network whilst in my pocket and me not know about it...

You have to unlock the bootloader to try different radio's. There is a thread about it in the general section. Try to reinsert the sim first. It fixed it for me when I had the issue

OK so I tried re-inserting the sim but still dropping network. The weird thing is that it has done 3 times in the exact same location on my way to work whilst I've been streaming. It's as if it loses 4g signal in that location but then fails to switch to 3g and instead I get left with no network connection / no bars (empty triangle). It then fails to pick up the network again until I reboot (tried re-registering on network and airplane mode on/off).

OK so re-inserted sim and spoke to O2 who said settings are ok. However, it did it again this morning in the same location. That's 12 times in 8 days I've had the phone, 4 of those in the same location (give or take 100m).
I think I'll take the phone back before unlocking bootloader and trying a new radio, but any other suggestions before I do that ? Factory reset ?

I never had it with my S3 in 2 years, using the same route into work every day. I can't remember my S3 ever dropping network once....or if it did it picked up the network again automatically. Only difference was I wasn't on LTE with that.
It's not just that location though, it's happened 8 other times in other place nowhere near. I only made note of the same location because it's where I get off the tram coming into work. This morning I wasn't streaming or anything, it was just in my pocket, but I'd installed light flow to audibly alert me when it lost connection.

Yeah I've seen suggestions about changing to 3g, but that defeats the object of me having an LTE phone and paying for 4g service. Thanks, I think I'll take the phone back. My mate has an N5 and although he said he'd experienced it in the past, he hasn't since being on 4.4.3 / 4.4.4

OK so I've been and swapped my N5 for a new one...they also gave me a new sim. Fingers crossed !!
I guess I am too late to add anything but anyway here is what I did and may be of help. After pulling out the sim, use a pencil eraser and rub it across the contacts on the sim card. If the contacts somehow get too much oil residue from finger tips or other "impurities" on the contact, you will get incomplete contacting sometimes and it works other times. The eraser will clean those contacts up for a better dirt free connection. When I was a electronics tech in the hi tech field, I fixed many issues that were just contact problems and the eraser did the trick. I have had this same problem on my other phones (blackberries and androids) and it seemed to work.

[Q] Mate7 4g data problem

Hi all,
I've had this great phone MT7-L09 (softare version L09V100R001C00B127) since last December. My problem is that every now and then the 4g cuts off for a period of ten seconds.
It does not matter how strong the signal is nor which or whatever app I'm using. It just loses network. First thing I did was to change the old sim card to a new one. Did not help.
I was in contact with the Huawei support and conclusion was to send phone to service. OK. It came back with the same problem altough they changed the circuit board...so obviously they though that this would solve the problem. I did not. After messing around with it, trying to find if someone else was suffering with the same problem, with no luck, I send it back to service. Now they said that there is nothing wrong with it, but the problem is still there.
I havent noticed anything cut offs using 3g. It's not a major thing but it would be nice to know if its a firmware or any other software related problem.
If I use Netflix or similar where the data keeps coming it works just fine or if I use the phone as Wi-Fi hotspot, no problems.
It just loses network connection using apps like play store, facebook, whatsapp, twitter, every browser ie. firefox, build in browser, chrome, to name a few.
Should I just keep using it as it is or keep sending it back to service until they fix this issue???
Thanks

Hi all,
I've had this great phone MT7-L09 (softare version L09V100R001C00B127) since last December. My problem is that every now and then the 4g cuts off for a period of ten seconds.
It does not matter how strong the signal is nor which or whatever app I'm using. It just loses network. First thing I did was to change the old sim card to a new one. Did not help.
I was in contact with the Huawei support and conclusion was to send phone to service. OK. It came back with the same problem altough they changed the circuit board...so obviously they though that this would solve the problem. I did not. After messing around with it, trying to find if someone else was suffering with the same problem, with no luck, I send it back to service. Now they said that there is nothing wrong with it, but the problem is still there.

Sorry...one stupid question: have you already tried keeping the phone completely stock (without any application and/or software or any kin dof personalisation) for a couple of week and see if the problem still exists?
It really seems to me a software problem. Very strange.
I had the same problem with my MT7-TL10 golden version. For a week or so, the network used to come and go. Then ultimately the sim was not recognized at all. I sent it to Huawei service center and they told me that the sim slot is broken and I had to pay for replacement of the board which I refused. I was sure that I didn't break it. Now I am using my phone with one sim only.

Thanks for your reply,
I haven't used it only with stock apps for a week maybe a day, but first thing when it came back from service for the first time, I did not install any apps and it still lost the connection anyway...

I'm not sure, but isn't the sim card slot located on the circuit board??? If it is, it cannot be the problem, but I must try the second slot anyhow.

Man why everybody blames PHONE first??? like not trusting !
To fix this problem is to go to networks and u have to restore your apn to default it like refreshes then you can either just turn off data and then on and restart phone

Does not work, same problem after a numerous resettings. If I may add, I've have couple of other phones of which this problem does not occur.
In same place and conditions these phones work just fine not losing the data connection. Sure, if 4g is not available they use 3g, but never ever will the connection break off.

faulty 4G module tuner.. phone ... replacement needed...
change preferred network
Go to settings and -->mobile networks-->>preferred network and select "WCDMA only"..
It will fix your problem..
There is no such option in my phone settings, only the option to choose automatic 4g3g2g or automatic 3g2g or 2g, 3g only and 2g only. As previously stated no data loss nor connectivity issues using 3g. It's bit annoying sometimes when phone loses data connection altogether although signal is very strong. Just waiting lollipop upgrade if it'd solve the problem, I doubt it but...
network operator..
I think it's network problem..please contact your network operator..4g network have connection problem from some local area signal towers..so you just put other network company SIM card in your local area..(use 4g supported SIM only)
Thanks for your advice, but I don't think that it's SIM card problem because there is no problem what so ever using my other phone SGS5.
sorry

Hmmm. Sorry friend..I am helpless.. anyway continue your thread here..in Xda have brilliant members..they can help you..best of luck.
Thanks, I totally missed your comment...this is turning out to be quite a puzzle. I've noticed the less battery (<60%) I've have on the phone there seems to be nothing wrong with the 4g connection. ???
To answer to myself, I was too optimistic...nothing to do with battery. It's just so weird that phone works like a charm most of time and then suddenly not. I'm confused...
Now on the newest firmware lollipop 5.1 it fixed my lte problem
same issue
I bought mate 7 a couple of days ago and I keep losing the data connection. the network gets connected and lost again.
i did everything to fix it but no luck. changed sim, restored device, modified APN and no luck.
it keeps disconnecting seems that it is a problem with the phone itself as i have read the same issue on a couple of forums..
hope it is a software issue and get fixed soon as this is annoying.
In service they replaced my phone to a new one mostly because of this problem and I can say it did not help at all. Only upgrading to lollipop will fix the problem ( tested on beta) I'm on b145 now and it does that all the time. I guess it is carrier based problem not SIM nor hardware.
