[Q] S6 network problem - Galaxy S6 Q&A, Help & Troubleshooting

Hi all, a friend has bought a galaxy s6 less then one week, and we have seen that the phone has a issue. The wireless network as 3G or 4G are slow to connect at the grid. It can be a factory problem or because was the sim cutted badly?
Thanks for help

Same here. On my N5 i was full 4G all the time and with the S6 just 1 or 2 bars. Worst is when it sayd 4G but there's no data passing.

S6 Edge Wireless Failed

Hi Guys,
Since I've done firmware upgrade on my S6 Edge last week, I have a problem with my Wireless connection, once my S6 stabilisted a connection with my router, all my devices cannot go to internet, all network seems freezed...

Please anybody realised same problem with their S6E?
I'm assuming edge has it's own forum. This is for those of us that chose to save $100.

My cousin bought an S7 Edge, but it had the same problems as listed. She then proceeded to change the phone, yet the other S7 Edge had the same problem. What could be the solution to this problem, and what caused it?

We changed two gold ones, awaiting for the third. Problem seems to be persistent.
Hi!
Go to settings and find your APN-settings. Remove IPv6 and save it. Then everything should work fine.
I'm having the same problem. I'm sitting beside my friend with his ip6s+ and he's not having trouble connecting with the lte. just saying that this might not be just a network problem.
I've read about multiple people, including me having this issue, for some the APN IPv4 switch seems to work, but not for everyone. So what is this? Is it related to the phone hardware or software? Or is it a network problem? And will it be fixed? As this is starting to irritate me a bit..
Many People in my country (indonesia) is having similar problem. The signal somehow stuck in 3g. Forcing it to use LTE only using the app "4G LTE Switch) makes the signal gone, emergency only mode. Only a reboot would bring 4g back.
However it only acts up when using one specific mobile provider (telkomsel). Switching to my second sim, also by the same provider, didnt help. But if I switched to another provider, the problem doesnt happen.
Widespread issue in Germany as well. It's carrier independent. Had to exchange one unit. The new S7 Edge I got works fine so far, but has a pink hue on the display. Samsung QA! -.-
Any solutions or updates?
Solved?!

Downloaded bulgarian firmware,, XXU1APC8 is the only one available. Tried to check for update, nothing yet to xxu1apch...
Update:
Emailed Indonesian Samsung Support, they came up with a temporary solution:
go to phone, dial *#9900#
select debug level disable/low
change to mid
wait for phone to reboot.
2 hours past no signal lost yet
update: 3rd hour signal gone again
hi,
has anyone found a solution for the problem above?
in my case I have really slow internet (mobile data) on 2,3 or 4G, it's like it freezes when I try to open a page
when I connect to 4G it maybe works for a second and then nothing else, it's like 2G, very slow (wifi works normal)
can it be hardware problem? I already cleared cache and reset the phone, but it's still the same..
At me the phone can not change back to 2G from LTE, if 3G network is unavailable.
If I use LTE/3G/2G option and somewhere is not 3G network I can't receive or make voice calls.
Phone only works with 3G/2G option in network mode.
But in this case I only can use edge if somewhere only 2G and 4G networks are available.
If I use LTE network, the phone doesn't receive incoming calls.
I bought my samsung s7 gold one month ago in Lebanon (Middle East). I faced exactly the same problem, I couldn't receive any phone calls. Went to the store and they told me to switch from LTE/4G to 3G. Now my phone is always on 3G and working ok so far. But I can't put it on 4G !!!
get new simcard will fixed problem
Hi, is there a solution to this?
got info that there is a patching from samsung for this issue but since i am using custom rom, i cannot confirm this.
anyone has any update?
Same problem! I'm from Mexico and i just bought my pink s7 Edge on sunday, i've been going everyday to the carrier store and yesterday they finally gave me another one but im having the same issue! I can't take it anymore i don't know what should I do Maybe all the pink ones have the same problem? They have already changed my SIM Card, i have tried with another one and it still happens
This sounds very similar to the LTE problem on the Nexus 6P I wonder if it is actually the same problem.

LTE drops Upload speed to 0.0-0.1

I bought the phone just recently march 22 and I been having this problem for about 3 weeks now and today I realize what was the problem. first I thought it was my carrier throttling my data but it was not my carrier. I swap sim cards on my phone and I notice that on 4G phone works perfectly fine. But once the phone goes into 4g LTE i still get some download speed but my upload speed is practically 0. And since there is no way to toggle off LTE I been practically living without data. But I found some useful apps that can remove LTE and leave me with just 4G but it is annoying to have this problem. Does anyone know what kind of problem this is? is it hardware or software problem? any help would be greatly appreciated.

Poor S8+ data hangover...Bad 3G/4G signal/performance

I thought that S8+ has better antenna and modem than my iPhone 7+. But I made mistake. It is far worse than 7+. Even I have full bars on 3G it switches back to 2G and if on 4G it switches on 3G. WTF Samsung!?
I need to access service menu and set 3G/4G only but I have another thread about service menu which I cannot access....
Go to settings, connections, mobile networks, and tap network mode. Is 4G/3G/2G enabled? If not, enable it, and see if 4G connects

Which Variant do you have? I had a similar issue when I first bought the Verizon S8+ to use on Cricket/AT&T. I ended up having to return it and get the AT&T one. The first one I had would run on 4G or LTE with 4-5 bars and would constantly loose service, and every time I would try to make a call it would switch to 3G and tell me that international calling was not on my plan until 3 or more attempts later. Then it would finally make the call on 3G network. Since I've swapped I haven't had this problem. No I still don't get as good of signal as my iPhone 7 plus but it's comparable now.

International Sim-Unlocked 955F variant (EXYNOS). It is OK to switch from 4G to 3G if operator doesn't support VoLTE on its network. But that is not my problem. Full bar 3G, surfing web and it switches to 2G. NOT NORMAL. Same as on 4G to 3G. Full 4G bars.
If you have tried factory reset and all other trouble shooting, I'd just set up a RMA and get a new one. If you are in the US maybe the Snapdragon if you're willing to sacrifice root. Sounds really annoying to have a phone with LTE and be stuck using 2G. Just my 2 cents
Got the same issue...

Hi Friend, it so true...
I use S8 Plus and experience the same issue. If we only use S8, we will never realized this fail but if we use another device like Sony Experia or Mi5 (my experience), we will realized that S8 has worse signal receiver. I complained it to Samsung through Twitter, just say they will check on it and never get back to my last message.
Kind of mess for an expensive phone and high class brand.
Same with me
