Mobile data problem only on 3g (edge and lte works fine) - Galaxy Note 4 Q&A, Help & Troubleshooting

Like in title anyone heard or had problem with 3g/h/h+ only ? All in all 3g WORKS(1 out of 10) but it has so many hiccups, it stucks with up arrow blinking so many times or changes 3g/h/h+ icon all the time, while on note2 with same sim works great, even when travelling...
Problem seems bigger when I'm in the country side (still with full signal bar, but a bit worse dbm which can be found in settings).
On lte and edge I think it never happend.
I have 910c with lollipop on board.
Do you think it's more software or hardware problem? I have tripped knox already :/

Suddenly ... "G" instead of "E"

Hi all,
I have an Elf, and use my phone "function" just for calls (no internet, no nothing else). Today I'm having some trouble connecting to my phone network, i.e. the device is "searching" now and then. Sometimes I can communicate, sometimes I can't. Sometimes I receive calls, sometimes I don't. This has never happen before! If I turn off the screen, the signal is just lost again!!!
Anyway, today I noticed that on top of the Today screen [Status Icons] there is a "G" [GPRS available] instead of the "E" [Edge]. The thing is that I never see the "G", but always the "E". Does this have to do something with what I am experiencing? How can I go back to the normal behaviour of "E"?
Sorry for my english. And thanks for any help.
hi gmorar, can you tell us more about it? what rom do you have?
maybe is just your carrier.
Saludos!
there are sometimes gaps in data coverage. Or possibly, your network is doing some work.
Thank you both for your answers. It must have been related to some work my network was doing. Today everything went back to normal .
Thanks again.

Network Signal Loss when finishing a call (?)

Hi everybody,
I have a really really strange and concerning issue with my brand new X1.
I had a HTC touch for more than a year, everything was fine - now with Xperia I immediately installed Touch-IT v9, works OK but very often (not checked if sometimes it does not happen) after finishing a call and pressing the "hook" button I can see in the top bar that for a few seconds (1-5) the signal is complete gone and like magic it comes back. I cannot believe that this should be normal with WinMobile, as the HTC Touch did not do anything similar like this. I'm forced to GSM/2G.
Please let me know if this is something specific to TouchIT, or Xperia issue, or just happens to my mobile? I'm little bit concerned as it is completely new and should not behave like this.
Best Regards, and thanks for feedback!

Are you sure the signal actually is gone? It is probably the redetection of current data connection type as the bars up there actually indicate the coverage of the fastest available data connection type. Like having one or no bar for EDGE you actually have all the bars for GPRS. No need to go to 2G for that technical eccentricity.
Does anyone have similar experiences. Today i had the same problem when sending a SMS. Its no problem at all, only GPRS sign goes to unconnected and also the signal shows the "!" for 1-2 seconds.
Am I the only one having this experience?

"GPS connection lost" where the s6 edge worked perfectly... several times...

"GPS connection lost" where the s6 edge worked perfectly... several times...
enough to miss freeway exits. Basically useless as the #1 use in the car (besides radio). I got a 935f unlocked from germany, no warranty, so I'm hoping badly this is some kind of software issue?
The GPS issue is so big I haven't even dealt with the battery being so low so fast.
So sad. :crying:
Same problem. GPS signal is horrible even when my phone has a 4G signal, always failing to keep up in real time . Then again my S6 edge wasn't great either.

Losing mobile network

I have a stock t-mobile s7 edge device. It's losing the mobile network. I've noticed it a couple of months ago - it happened a few times but recently the problem is getting worse. It already happened 3 times this week.
Seems like completely random. Sometimes I notice it after I go somewhere with weak signal or no signal at all. Sometimes when I get back to an area with good signal it reconnects and sometimes it doesn't. Sometimes it shows the bars and says it's connected to t-mobile but 4g doesn't show up at all. So you can call but no internet. Sometimes no signal at all.
When it happens the only way to connect is to reboot the phone. Nothing else helps. If you try to connect to network manually - it can find t-mobile but unable to connect. just spins. Changing from lte to 3g or 2g also doesn't work.
I even tried to create a new APN - same thing.
Please heeeeelp...........
Last time this happened to me on another device, it was the sim card that had a problem. Have you tried with another SIM card?
No, but I don't believe it's a sim card related problem. Wife's phone has the same problem although less frequently. But she also travels less.
It looks like a configuration / firmware or maybe hardware issue to me.
I'm experiencing the same issue. It seems to happen when the phone loses signal completely like when deep inside a building. Then it won't reconnect to data or the network by itself.
From the first moment when I got my edge back in April I noticed that the radio performance was weaker than other phones. Then I got the Note 7 and same issue again. Then back to an s7 edge and the problem seems to be worse on this one specially after the latest software update.

My wife (s7) and me (s7 edge), as well as a co-worker (s7) are having this same issue.
Before it was happening occasionally, but after the last update its happening WAY more often.
Wiping cache seems to help with frequency, but still did not eliminate the problem. Hopefully it gets fixed with an update. I'm not sure how much longer I'll be able to put up with it.
Edit: I forgot to add a "simple" fix I've found that works almost all the time is to turn off mobile data, turn on airplane mode, turn off airplane mode, wait for signal, then turn on mobile data. Those steps in that exact order work for me most of the time.
So I've been having the same issues as everyone stated. The only fix is to reboot the phone, but who wants to that every time. I even changed the sim card!! I wish T-Mobile would get out of their feelings and start selling more flagship phones.
I have made the decision to jump to LG V20. I hope this issue doesn't exist with the LG.
I've just got my s7 edge and I'm sort of having same problem at home got 2 bars and sometimes goes to 4 bars but also wen I called someone the line was crackling but person said could her me fine so done a wiped cache and think it's sorted it now for the time being
(Edit ~ it's done it again could hardly hear person I was talking to)

Network Reception Weakened/dead (US996)

My phone suddenly started having trouble with network reception yesterday. I have relatively poor reception in my area, but I still used to have 2-3/5 bars. Now I have no reception at all. And in other areas it does have reception but I never see it go up to 5 bars. The network bar icon keeps rotating for a while and then just ends with a cross. Today even the mobile networks settings menu option was grayed out until I restarted the phone.
I havent changed anything on the phone. No problems with water or any other hardware damage happened as far as I know. The only recent things that changed were that I got a 4200mah battery (which kinda makes the back cover bulge a bit or pop open easily) and I changed the phone from whatever stock based nougat rom I had been running for the last 1.5 years to a stock based oreo rom. But both these changes happened about a week ago, and everything worked fine until yesterday.
Anyone else had a problem like this or know what this could be? I'm gonna try reinstalling the rom and restoring the previous battery but if these things don't solve it I might have to move on to something else, which I really dont want to do as nothing out there really appeals to me.
Who is your carrier? Which specific model phone do you have?
I also have problems with calling the function on my f800l. At some places, I cant make a phone call but mobile data works just fine. And if i try and keep on calling the network resets.
