My phone acts weird on the network mode 'gsm/wcdma(automode)'
It works perfectly when I select 'GSM only'. This means that I have the APNs right
But as soon as I select the automode so that I can use 3g, phone starts acting weird. For starters the internet does not work. I also lose my voice service. The bars show that I do have voice service, but on making any call the call doesn't go through, and on ending the call the call remains on the notification bar. But if I dont end the call, then it does eventually shut by itself (~15secs) and then the bars disappear and I lose service. At this point my phone has automatically gone into flight mode. On turning flight mode off... the cycle repeats (with some exceptions)
1.notification shows service coming back: 3G, full bars for voice service. (Sometimes 3g doesn't appear at all, and at this point internet does not work but I can make calls)
2.but internet does not work (but if I keep trying it might work for a few seconds. Noticed that because network mode is on auto. Notification bar shows switching to GSM, and then back to WDCMA. On repeating this the internet lasted longer ~a min or two)... and then doesn't start at all (basically its very random)
3.make a phone call and call doesn't got through, lose service and goes into flight mode

I had the same issue on Tmobile, only gsm worked. Even tried creating another APN and still nothing.
are you there guys ??
Does wcdma only mode work well? I don't even use gsm/wcdma mode because its a battery waste juggling that extra variable. Gsm mode only used to be used as a battery saver for many reasons, but since hspa is so abundant and umts is so efficient, I exclusively use wcdma only mode as my battery saver mode. Really need it too since Samsung borked the reception on the note 3 compared to note2. A phone this big and there shouldn't have been any compromise in the antenna department. I am also hoping for a LTE/wcdma auto mode. I know I probably haven't answered your question but it is alternative and personally I think more efficient than gsm mode only considering how well hspa has evolved and the bandwidth on umts is still worlds better than edge or GPRS.

wcdma and dual mode are making this issue
the gsm mode only works properly . .
if i switch the data off ,the phone works fine
i really don't know what to do
and i have no idea if i void the warranty or not but i unroot the phone and no recovery or root installed now . .
I don't know if you wanna try, but maybe a factory reset will fix your ills. A lot of people, including have been having success with a myriad of issues and factory reset has been fixing it. I am guessing what is loaded at the factory by default has been buggy but the factory reset is loading phones correctly. There are still some bugs here and there even after resetting but the phone has been out less than a month. Need to give Samsung, especially xda devs some time to works some of the kinks. If a factory reset doesn't fix your issue then phone is probably wonky. Also, just to be you are using the correct phone for USA and not a European model?

I am facing the same issue. It started today. It doesn't matter what network mode I select WCDMA/LTE/GSM the Phone function doesn't work. The internet works but I cannot call anybody. It just disappears. I can receive calls. I am starting to think this is a bug. I really don't want to factory reset the device. Are there more reported issues of this?

Sorry I forgot to mention that i made factory reset 3 time and tried to install Stock Rom as well and all of that didn't help . .
Then it serious bug or hardware. Possibly new radio flash might help, but I don't recommend it unless somebody with more knowledge recommend s it.

apparently yes.. at least for now.. It may have something to do with the way I changed the network type. Normally if you do it from Mobile Networks> Network mode.. you will be fine but I created a Nova shortcut instead to get to it quickly. This shortcut looks a little different the way it opens the Network mode selection so maybe choosing between LTE/GSM from here screwed it up for me. There is nothing else I did before the phone functionality died on me.

I have same problem did u manage to solve it?? And how?
Thanks
No. I can't even get into service mode on my phone through dialer or app. Frustrating. A few people have the same problem not being able to get into service mode. Its a minor inconvenience so I haven't pursued a fix. Dont wanna fix what ain't broken. I am on an int'l rom btw and there is no LTE/wcdma mode either.
sent from my sm-9005.
I have started to experience the same issue, I changed the mobile network type to GSM only and this seemed to help with the quality and connection of calls, having it set to GSM/WCDMA (Auto Mode) causes bad quality of audio/connection of calls, and even sometimes I will hear the number that I am calling ring then it will just stop and I have to end the call.
Any possible reasons for this?
Factory re-set didn't help in my situation.
There is no way to fix it yourself. I had the exact same problem. had to fix it from a shop they have SPT box to fix it. you can do it yourself if you can order it from amazon probably 216 bucks
Just take it to a shop mate.

The issue I am experiencing is either incoming or outgoing calls on the GSM/WDMCA mode when the audio just goes and then can come back again, no issues like this using GSM only, so my phone has gone for either repair or better still a replacement as the other issue with it is that it is lagging on many occasions even when just moving from screen page, and also when playing mp4 videos.

This is an issue that a lot of Hero users had. I was fortunate enough to not experience it with the Hero, but my current time without signal is 52% on my Epic. If I remember correctly, it was a PRL problem, but it might also be the radio. It would be the cause of serious battery issues. I've attempted updating my profile and PRL to no avail. Is anyone else having time without signal issues?
To check, go to settings -> about phone -> battery use -> cell standby.

I thought it was just a reporting issue
Sent from my SPH-D700 using XDA App
No. I remember what it was now. It was that the Hero wasn't set to use CDMA towers and was searching for GSM towers for some reason. Something to do with the fact that the Hero was originally a GSM phone, which would make sense here. Someone in the thread that was created just a bit ago suggested it had something to do with the PRL update, which is possible, because I did it and that's when I started getting bad battery life and a high percentage of time without signal.
I've been having a hell of a time with my data connection today, which would explain my poor battery.
I've got a very high time w/out signal as well... I'm surprised this hasnt gotten more attention. Its a huge battery drain.
...
I've got 50% time without signal on mine. It seems likely that the searching for GSM towers could be happening on this phone as well because of all the material that crossed over from the international versions. Is there a way to check and/or fix this problem and get the phone to only search for the CDMA towers?
Thanks,

I've been trying to set the network mode to cdma auto using the network app i downloaded from the market. I dont think its fixing the issue though...
Strangely enough this is a similar issue I have seen with the Samsung Intercept. Especially having a hard time with keeping the data connection...

Haven't have this issue and I live in Puerto Rico. We have 5 carriers on this tiny island and Sprint is the only one with CDMA.
I think I figured it out. I set my network to cdma auto and my time without signal dropped to 3%. Battery drain seems improved in the short term...
Did you set yours up to WCDMA only? If I went WCDMA Preferred, I can see it was trying and failing to connect to GSM.

Go to the android market and search for an app called "Network"
Open up the app, you should see WCDMA Preferred in a drop down box near the bottom of the screen. Select that and change it to CDMA auto.
Exit the app.
Your Time without service should drop really low (mine went to 3%)
I've had the app behave strangely and revert my settings. I'm paranoid so i've been checking it pretty often. I'm not sure if there is a way to make this change permanent. I dont know if it reverts when the phone is rebooted.
The way that the problem was solved on the Hero was by accessing a system menu through a ##CODE## code and telling it to prefer CDMA towers. It was defaulted, for some, to GSM. Because I never had this issue, I don't know a whole lot about it. I know that ##CODE## codes are not available on this phone, though, so we might be out of luck until we can get into some kind of dev menu, I think. The app fix mentioned above sounds janky as hell to me, though, so I'll avoid it for now.
My phone has a hell of a time holding on to a data connection right now, but Juice Defender is really helping that not absolutely kill my battery. Aside from this one concern, my battery is actually lasting a surprisingly long time. I was expecting it to die nearly twice as fast as my Hero, but it is definitely giving it a run for its money. I'm very pleased with the Epic
...
I followed your directions. Got into Network, changed the dropdown box to CDMA Auto (PRL) and then hit the home button. Nothing changed, so I went back into the app to check if it stuck and it was back at WCDMA Preferred. Am I missing a step to make the change stick or something?

Yea, Thats what mine looked like until I fixed it with the Network app.
Yes, I have been playing lots of games/angry birds
I have been trying to use the Network app that people are suggesting but I am getting some weird issues. When I open the Network app it says I am on "WCDMA preferred" but then if I just let it sit for about 15-30 seconds it changes to "Unknown" without my pressing anything. I tried setting it to "CDMA only" and to "WCDMA only" but it doesn't save either setting. If I exit and reopen the program it goes back to "WCDMA preferred" and then changes itself to "Unknown" after a short duration. Anyone else have a problem like this? Any ideas?
Few issues...
1. This one has never been addressed... Even with my G2, and with vibration set to always, my phone never vibrates for incoming texts, MMS's or emails. How do I make this work? I have yet to use an Android ROM, even stock out of the box with the phone, where this works.
2. From time to time, T-Mobile is replaced with (No Service) on the lock screen, even though I have service. This also happened with my G2.
Both issues seem to be a bug with Android, probably at the kernel level. Anyone know of a fix?

Your No Service issue is probably because you have your phone set to WCDMA Only instead of GSM/WCDMA auto. When the 3G signal is not present there is no GSM/Edge signal for your phone to fall back on.

Hm...makes sense. How do I change that? Went into Wireless Settings, didn't see it.
This is my 3rd Sprint S4 over the past few months. All of the devices are loosing the 3g icon but will show bars. Voice and text works fine, data and 4g does not, i have noticed it usually happens when i leave a WiFi area and it has trouble switching back over to cell data. I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?
This happens to me as well. Just Sprint being crappy. Try turning airplane mode on and off, same effect as a reboot but faster.
I tried the airplane mode toggle but didnt seem to fix it. If i use even the "Hot reboot" option in triforce rom that doesnt fix it either.
Assuming this this is the same issue I always experience, there is no fix. It's a network thing. Is there 4G in your area?
What happens to me is my phone will be on 3G, then start receiving 4G, but it doesn't recognize that the data service is now different, so nothing works for 15+ minutes or until I toggle airplane mode on/off.
I take it you've tried just turning WiFi off?
Haha, yea, welcome to Sprint. Enjoy losing data when it's least convenient (such as when you need to use navigation or missed your exit and need to be rerouted). Oh well, the price we pay for unlimited data, right?
I have noticed the same thing since I activated my LTE radio. LTE is expanding in my area so I constantly go in and out of 3G and LTE service. Sometimes when this happens data just ****ing stops working until I enter airplane mode and then come back out of it (a reset works as well). For some reason (or it is just a coincidence) The problem has amplified since installing 4.3. Has anyone else noticed an increase in this problem since upgrading? This is absolutely a Sprint problem? Do we know that people have this same issue with other Sprint phones?
I have the same problem. From wifi to f data takes a little bit of time for it to switch over especially since the data toggle is gone with the 4.3 update. Unlimited plan is water downed from my experience compared to tmoblie. But tmoblie service was horrible.

If wifi is on 3g/4g is not there,, turn off wifi and you should see icon,, if you see bars it's most likely working :sly:

Seems like a hardware problem based on your description. I am fully convinced that this whole flashing modems things is just a feel-good measure for people who have exhausted all other options. It was big in the Galaxy S2 days, but I have never seen any measurable difference between modems in any meaningful metric on that device. At least not one that could not be attributed to other factors such as signal quality and network load, and nothing consistent. A different modem isn't going to fix a hardware fault or magically improve Sprint's awful service.
As the title says the signal drops on my s4(gt-i9505) alot.I've been searching over the internet to find a fix but nothing helps.
The sim card is brand new so it.s not the sim
The firmware is updated to latest version
The imei is the same as it writes on the back of the phone so it should be right
Even if the signal is poor or strong it drops randomly and the only way to fix it is to restart the phone.
I also tried to factory reset the phone many times
Even if i set the network mode only on 2g or 3g it does the same thing
I'm from romania and the service network is on Vodafone
Android version is 4.4.2
I dont have waranty for the phone so i'm tring every option i can before sending it to a service center.
I try to belive there is a glitch in the soft and not hardwere fault
If there is anything else i can do please tell me!
This happens to me sometime, the only thing that I do is I switch to airplane mode then switch back again then wait a couple seconds then it restores to the right or proper network coverage. What happens is you experience is that the signal suddenly drops right?

Yes the signal suddenly drops and even if i try to swtch to airplane mode and then back again it's not doing anything.
And in the past few days it became more frequently.It's not passing half an hour before the signal drops.
Did you try flashing different modems? That would be my point to start.
Yes i did flash a new modem but it still keeps droping.
I will try other modems since there are more avaible for my country.

Im in Norway with Telenor subscription. When my Edge+ is LTE/3G/2G (auto connect) Im experiencing several issues:
1. During phonecalls:
- Several times during a call, I can hear the other party, but they can not hear me for several seconds
- The sound become "static", and the phonecall ends.
2. During browsing:
- Page never loads
I cant find any system in these problems, they can happen in places with good reception, or it can be during driving (handsfree).
But all these issues disappear if I set the phone in 2G only, then everything is working perfectly.
What I've tried:
- Reset APN
- Enter APN manually
Any suggestions?
I'm in Norway too but with NetCom. I've used my wife's Telenor SIM card in my Edge+ a few times, not really noticed any difference except for slightly worse sound during calls. Har du ringt Telenor?

I'm not locked, so I will try a simcard from a different operator. When I have auto connect (LTE, 3g 2g) its constantly shifting between H and H+.
Where I'm now, the signal strengt is stable on -51 dBm 31 asu (Mobile network type EDGE).
Switching to (LTE, 3G, 2G) its -65 dBm 24 asu (Mobile network type LTE)
I can confirm having the same issue #2 as OP in Sweden with Halebop as my carrier, but I only got it once and since then there has been several security updates so I though this issue was one of the things fixed (thanks Samsung for not supplying a proper changelog)
I've just tried with two Telenor SIM cards from my wife and son - both work fine. I'd contact Telenor again and ask for real help... Their customer service is dreadful, that's why I switched to NetCom. Lykke til?

Got the new SIM-card last week.. Same problem, people people can't hear me for 3-10 seconds several times during a phonecall. And data seems to "hang" from time to time. Tried a full factory reset this weekend, so are going to test more next week. And then try a Netcom SIM-card

Just to recap
I returned the phone, and I just got an email from the repairs workshop saying it was a warranty. I dont know if I get a new phone, or if they have repaired the old one.
update: got an email from repairs workshop. They did a network calibration and "reinstalled software". After that they tested the phone OK. I think I will get the phone this week.
I have same problem now, only work on 2g. When on 3g phonecalls hanging all the time.

Same problem here.
In general, the problem is not with the sim card neither phone hardware. The problem usually is with any app that we have installed. To ensure this, switch on the phone in SAFE MODE ( safe mode temporally turns off all user-installed apps). To do that:
1. Switch off the phone
2. Wait at least 1 minute
3.Press and hold volume down button AND the power button
4.Once screen lights up, you can release power button but you should NOT release the volume down button
5. Hold the volume down button until you get the lock screen
You will notice there is a Safe mode icon in bottom left of the lock screen.
Now try to do some phone calls and accurate if the phone call sound is ok. If so, you must uninstall all your apps and discover which one is making this problem

Are you talking seriously?? First of all, I think that finding out that the problem isn't neither from sim card or hardware, is a great new, and now you are asking which app YOU have installed is the problematic?! Lol ok, I suppose to believe you're naïve and I can help a bit...
It is not necessarily only one or the same app for both. Sometimes can be one in conflict with another also installed, one in conflict with the specific firmware of each one or one of several app's with low maturity (you can check it in Google play). I can give you an idea: for instance, periscope app is very problematic in android. But there are a lot of a lot problematic app's. So, as they are so much, there is only a solution if you don't have an idea: uninstall all of them ( phone hard reset preferably) and after this, install one by one manually (not restore any backup cause the errors come again). After each app installation, make some calls to check any call sound problem. When you notice the problem in call sound, the cause is in the last app that you've installed immediately before this. For next time, check with attention after installing any app if any problem appear and never install several app's in the same time to have time to notice problems in a narrow way...
Anyway, you can write here your conclusions
