Data Connection Issues

Have anyone experienced data connection issues on the AT&T variant, some of my apps like Craigslist won't open, but it will on other devices?

Yes. I am having issues on my Sprint Note EDGE. The signal goes up and down and the data is very spotty only giving me any data about 20% of the time. I am waiting on my replacement but I doubt the phone is faulty.

My issue is now turning out to be one app, which is Craigslist. I can't connect via AT&T data, but I was able to use a Verizon Hotspot to connect.

I have noticed data & wifi connection dropping frequently. I have been blaming my mobile operator and internet service provider until I saw this thread.

On my T-mobile Edge i was getting Wifi drop outs every minute or so.
I am getting a replacement tomorrow and I will report back.
here is what my battery stats looked like

Firmware.....
Its a Firmware issue
Guys I am almost positive this issue is due to a glitch in Samsungs firmware. I tested the data and was able to download over 1 megabyte per second with only one bar on 4g Spark LTE.
According to the tech support person I talked to that would not be possible on only 1 bar. (btw I stopped the test after hitting 1 Megabyte per second for those that need help converting that equals 8mbps). I was in a saturated 4g Spark network with 5 towers within spitting distance from my location and it still only showed 1 bar. I'm thinking either how the tower reads the signal strength or a bad code line shows no more then 1 bar no matter what.
Now for those having dropped data. Check the Sprint {if you are on Sprint or your providers site for a similar coverage map) site to see the saturation for 4g Spark service, the phones are now setup to LOCK on and HOLD onto the FASTEST tower, which according to the tech who also filled me in on the way the new antennas work, can lead to what seems to be dropped service. She would recommend for individuals having this issue if Spark service is not fully activated in your area to switch over to CDMA only under settings to fix the LTE data dropping issue. BTW the Spark LTE service is apparently different then the old LTE service so those versions do not appear to work interchangeably (according to the Sprint service map). I'm assuming this new triband lte is new for all the carriers but maybe not...
I also noticed someone else got the new version of the firmware, which I also have and that did NOT fix anything for me. If anyone is struggling with this issue I would wait until the firmware is updated again. WHICH I hope by that point we can get flashable firmware for those of us that are rooted...???
Now for a VERY Important Fact: there will now be no way to use data while on a phone call. These phones are a single antenna model. You can either be on the phone or data... UNLESS you are making a WiFi call. That is why this is now a option. It will keep the antenna set to the data side of things and make it possible to use data for the internet at the same time.
I hope this helps.

Thank you for the info. I agree it has to be a firmware issue. I am getting a replacement handset tomorrow to verify that but I can see all these hansets being bad. I am in areas all day long with strong lte/spark/and 3g but my data connection constantly drops. I do also see the cellular signal shooting up and down but have no issues with my call quality at least. Have to reboot...toggle airplane mode....or shut data off and on just to get a little bit of 3g service for a second or two. I really hope the firmware update comes soon. I also went under networks in setting and set it to CDMA only and it as at least seeming to give me a steady 3g connection for now...will reply if that changes

signal
I had the note 4 for 3 weeks before giving it to my wife and getting the edge....the note 4 in all my normal travel was perfect....now with the edge i have horrible data so its something i hope they update quickly

I don't rely on the stock signal bars, they are not really reliable in my opinion. Instead if you install SignalCheck Lte or SignalCheck Pro (for those that are rooted) from the play store. It accurately shows the true signal strength of your connection.
I like the Pro version since it allows to reset the connection quickly if need be.

[Q] - [POLL] Is Your Galaxy S6 Switching to 3G Too Often, 1X Signal or Lousy 4G?

This is not meant to be scientific, however I am trying to get a gauge if this is a larger issue that what some have posted. I have a new Galaxy S6 that I activated on launch day. My previous 2 phones are and S4 and S5 most recently. I am fairly savvy in knowing my network strength locally and places I frequent. Since switching to the S6 from my S5 I have been on 3G in know very good 4G areas alot of the time. Not only that but I have seen the dreaded 1X more times in the last few days in areas I have had religiously great 4G coverage on for years. I have dropped 3 calls of which I havent done in probably 4 years as well. I have done tests with an S4 and S5 right next to my new S6 where I can pull 15-20Mbs on either of those two phones where my new S6 gets between 0.5Mbs and 1.5Mbs.
I have checked the signal strength between the two sitting right along side each other S5 (111DBs) - S6 (98DBs) I personally have no idea the order of magnitude between 1-10 DBs if that would make that much of a dramatic difference, but real world testing there is either something wrong with my specific unit or hoping its not extremely widespread. There is a thread in general that we have been posting to but the change has been so dramatic if it was more widespread i would think alot more folks would be posting. So in order to find out if this is specific to myself and a few others in that thread or more widespread hardware/software issue I am throwing up a poll. Please take a few seconds and vote.

i work in my basement in a major city area and all my previous phones would get 3 bars of LTE in my office here. my S6 Edge gets occasional 1 bar of LTE mixed with 1X very often.
i am connected to wifi here and it hasnt affected my using it for work but have noticed this and prefer it worked at least as well as my older devices.
i am generally not a "numbers" watcher on things like this or battery and more of a "as long as it works as i need it" user but i noticed the 1X because i am not use to seeing it.
also i should add that i noticed under battery that #1 for me is always "Cell Standby" and i have to assume they are related?

So far every time a Verizon user has had Cell Standby at the top, it's been with wifi on. After your next full charge, leave wifi turned off completely for awhile and see if Cell Standby shows up at the top again.
What makes this a major problem is the fact that Verizon's VoLTE is fully dependent on a decent LTE signal.

i have read that as well and i guess i could do that but i really need Wifi on when my office signal is so often on 1X

Yes testing it today, it is very bad. Getting about 1Mbps when not using Wi-Fi.

Our new S6 is doing this same thing. Jumps from a strong 4G signal to 1X with no signal the second you make a call. :crying:
Is there a fix for this besides returning the phone?

Enable advanced calling on your account and on your phone. Also switch from Global to LTE/CDMA

OK, But than I loose my Caller ID / Name / Number. I need the caller ID.

Then buy the Caller ID feature. Your phone is switching to 1X when making a phone call because the S6 doesn't support voice and data simultaneously unless you have Advanced Calling on and enabled and are in LTE coverage area. The S6 only has a dual band modem.

HD Voice feature needs to be turned on, but don't!
Hey guys I've talked about this in different forums and sites, I'll copy and paste it here and hopefully it will help you understand why you can't place calls using the 4G LTE without having the Advance calling feature turned on under the Verizon network.
"Verizon is aware of the HD voice/video feature being the culprit of the dropped calls, they are blaming Samsung for not pushing an update to correct the problem. Meanwhile Samsung has said that the feature is a Verizon software. I was told by their tech support that it has been reported that there's a 50% dropped call increase using the galaxy S6 while having the HD voice/video feature on, this was 2 weeks ago. The agent said they have a search tool like Google search, this is internal and that's where he found this information.
You can not make calls and surf the web without the HD voice/video feature on, but turning this feature off will STOP THE DROPPED calls. Verizon's software side for galaxy S6 does not allow you to make calls on the 4G LTE network when the HD voice/video feature off, instead is shows 1x.
I have been in touch with Verizon wireless tech support for the last 3 weeks now, this past week Verizon has been sending me texts to update me on the progress of my ticket. I've had Samsung tech support in conference call with Verizon tech support; during this call that lasted more than 3 hours Verizon admitted that it wasn't a Samsung problem but Verizon's. As soon as the tech from Samsung hanged up the call because we were told that I would have to call their engineering department to further assist us. Before the Samsung tech agent hung up the call we had asked if I could make calls using the 4G LTE and was told to hold up while he researched this question. As soon as the Samsung tech agent left the conference call the Verizon tech answered no, and proceeded to make a complete 360 on answers he gave prior to the Samsung agent leaving the call, saying that the problem was not a Verizon but Samsung problem, even though moments before he said that it wasn't a Samsung problem to me and the Samsung tech support agent but Verizon's. I was also advised by the Verizon tech agent that if I wanted to, I could JAIL BRAKE my Galaxy S6 and download a software to disable the HD voice/video feature without losing the 4G LTE but that it probably still won't work properly. I told this agent that I've never jail broken a device and don't plan on because this is clearly a Verizon feature not working properly.
Not even 5 minutes after ending the call with Verizon's tech support, a supervisor from Verizon called me to tell me again that this is a Samsung issue not Verizon, he said that Samsung needs to push a SW version update to fix the problem with the HD voice calls dropping. He asked what I wanted, I said to get the Galaxy S5 and return this phone, but that I was told by 2 different stores (Rockville Centre NY, and Merrick NY both in Long Island) that if I wanted to return this phone or exchange for a different one I would be charged a 40% restocking fee even though I was within my 14 days. I was told by the tech before the supervisor called that it was at each store's discretion whether they charged you a restocking fee or not. I was told to consider this mater resolved by the supervisor, that they will get in touch with the store so I can return the phone and if in fact there are any fees I would be refunded in some sort of credit; but all I've received all of last week is text messages letting me know they are still working on my ticket."

ok i know this will sound crazy BUT i cracked the screen on my S6 Edge and got sent a new replacement (after deductible) and i swear in the same basement office i was using my original release day S6 my reception is much better.
i cant say if i just needed to do a reset on the original or what may be at play here but i can say with certainty that using the new one all day today i have not seen a single 1X or even gone below 2 bars where my original was often on 1X sitting in the same chair and location. no doubt its better but cant say why for sure except i am using a new device.
sidenote - the screen on my 1st one had much whiter whites and this new one has a slight more of a yellowish tint to it but this is not an area i am over concerned about and just something i noticed right away and then held them side by side before i shipped the cracked original back

Interesting. Unfortunately I've had three S6's and all behaved similarly with weaker LTE signal and more frequent drops to 3G.
Also, the screen thing is the one thing that bugs me about amoled, and qhd amoled at that. On my third device and all three have had some variation of the pink hue, and while quite subtle, once you see it you can't unsee it.

Don't know if people are still watching this thread but my signal is awful! I have an international variant here in Alaska SM-G920I... The firmware is from February! Did an update fix your issues with poor signal?

Exact same situation here. Work in the basement at my house in a major area; down here I get 3G or 1X. Upstairs i'm getting 3G or 1bar LTE and it flips a lot. Battery seems to drain like crazy when this is happening, and I'm on WiFi the entire time. I had a total of 2.2 hours SOT yesterday and was at 14% when I plugged it back in. Cell standby was around 35% at that time.

I've noticed lately my S6 keeps locking onto 3G only even though the BRV T1114 running my home internet stays on LTE without issue. I had to ODIN my S6 cuz I messed it up then like a bonehead applied the OF1 update without thinking now I can't root it. If I could, would it be a good idea to lock it to band 13 all the time? That's what the T1114 Router uses and stays connected all the time. Sigh.....
I've noticed that if I leave it sitting on the table/bed for a while, it locks to LTE then when I start using it again after a minute or so it goes back to 3G only. Damn.

I saw 1x quite frequent with an s6 and a black screen that only recovery booting would get me powered on. Before and after rooting. But I unrooted and return and exchanged it and now all is well no more 1x or black screen issue knock on wood

My Samsung rep at work said its due to the S6 only having one antenna vs. the S5 having two antennae(s).

That technically shouldn't matter because one was dedicated to voice only, but who knows at this point... I'm kinda tired of Verizon's inability, 4 years after the fact, to handle the LTE/3G handoff and "hold onto" issues.

Poor Signal After Receiving Phone Back from Samsung Repair (UK / EE)

I picked my phone up from my local Samsung Repair Centre last weekend and my phone signal has been very poor since. Is it possible something else could have been disturbed during a camera repair? I'm having trouble just sending texts, let alone browse the web, the majority of times I look at my phone it's either 'Emergency Calls Only', or no network at all.
I had my SIM card in a Nexus 4 whilst waiting for the S6 to come back, could poor signal be on the Network side due to this switch? Is there any way to test possible causes, any useful apps for troubleshooting?

Hi,
When i got my S6 i had very poor reception. The solution for me was to switch from 4g to 3g. Settings-Mobile Networks-Network Mode-switch to 3G/2G (auto connect). Now i don't have 4g but i have full signal. I hope this helps.

Question UK Phone Signal.

Hi. Does anyone in the UK find that they are having issues with keep signal? So far I've been a few places where my Note 9 would have great signal but the flip is either patchy or just disconnected from signal altogether. I'm on Three but haven't tried it with any other network. My Note 9 was also on Three too.

O2 UK poor signal as well...

@Barmenchik
That was the next service I was going to try. Hopefully when Samsung does an update it will fix it.

I'm with EE (Everything Expensive) and cannot get a signal when I'm in my local curry house, never had this happen before with all my other phones hmm

I would tend to agree, I'm on Three and at times I have a really low signal in areas where it should be strong

I've just moved to the UK and I found it rather weird that when I'm on EE I see 2 bars of reception max, pretty often only 1 bar. But then I had nothing to compare it to as it's the first time I'm using a SIM card in the UK...

My reception is still very patchy. Only time it is consistent is when I'm at home, but it does use wi-fi calling a lot.

Yes I noticed this from day one, contacted samsung and they said send for repair.....but I feel its more a software thing. Although the signal gets worse when it's flipped too. Someone on Samsung members forum said they thought it was a smaller than normal antenna and they sent it back!

I'm hoping that when it gets updated to Android 12 it will be better.

Question SAMSUNG S22 ULTRA

Hello,
i had small software update August 29,
Galaxy S22 Ultra (SM-S908B),
since then i keep loosing mobile data and wifi signal.
I got new Sim card and I did factory reset, but issues are still here. Turning off/on airplane mode or restarting the phone doesn't help. I have normal data like 5 min and then it just freeze all signal reception . I live in the city with great signal coverage. What should I do?

But what's the coverage like where you live? Does it get better as you move around? If the coverage is good then contact Samsung support so they can maybe check the phone further

Coverage is great here. I took out my sim card today and was only connected to wifi, connection is better.
With inserted sim both wifi and mobile data reception is awful.
I was thinking to switch to eSim..

I recommend that you contact Samsung support as your phone is under warranty for 1 year. They are very good at diagnosing problems.

Hi, you mean 5G coverage? I've read that 5G antenna failure is known to happen in this phone, so you should bring the phone to Samsung so they can replace it, specially if you are under warranty. I don't see why you see a relation between the SIM and the coverage, probably it has more to do with the status of the antenna.

The problem is with both data connection, mobile and wifi.. I tried everything coz I want to avoid sending my new phone to service..

Samsung has an 800 support number you can contact 1st and they will try and diagnose your issue before sending it in. I've found they are pretty good at diagnosing issues over the phone.

Well I notice that if I take out Sim card from my phone that wifi has weak but stable connection.. With inserted sim card both wifi and mobile data connection are super weak and unstable. So basically I have this expensive with no possibility to use for normal calls

It's quite the same problem for me actually on my S908B which is on the latest September update (AVI3)
I live in a quite big city in France and my signal is quite bad, like 1 or 2 signal bars on 4G+ (i desactivate 5G as it drain too much the battery in my opinion).
Sometimes i feel like Wifi signal struggle as well at home... i don't know where this is coming from, but it's annoying me. I didn"t pay attention on when it's started to get bad signal, but it's been a while now i think
