Hi all,
I have an SPH-L720 (not a SPH-L720T). Everything was fine with it on NAE firmware and CM11 nightly.
Recently, I used the upgrade available on my line to get a family member an SPH-L720T S4 for her line. When it activated, it kicked my phone off, but then I just did an ESN swap online. No biggie.
My S4 is back on the original line. So I went back to stock to update profile and PRL. Everything seemed fine. This was 3 days ago.
Since then, I have had poor signal or signal cutting in and out like crazy. I even thought it could be ROM related so I flashed back to Stock NAE and was still without signal in a place I KNOW had decent signal for a full day.
Given I have been on the road and drove 700 miles the past couple of days, I can't say what signal should be. However, most of the time my phone has said "NO SIGNAL", two of my family members have S4's and have had at least a bar or two of 3G.
I have seen digital roaming quite often, and also LTE has been great in high signal strength areas. I have seen non-roaming 3G, but not very often.
Any idea what could cause this?
Also, I know this is ROM related, but why is there no longer an APN menu to switch or edit them in CM11? I am actually wondering if the phone isn't switching APNs properly.
I am going to go back to stock right now and see what I can find out.

Hey there people.
Hoping I've not missed an existing thread.
I'm having problems with X10 dropping its signal seemingly through its own free will. Had phone since mid april and not had any problems with. But the other week me and the missus noticed occasionally i wasn't receiving texts she had sent me. This happened every now and again for a few days. I then noticed when i picked up phone it'd show signal on 3G as maybe 2 or 3 bars then suddenly drop too nothing, showing the little x indicating no signal. After a few seconds up to a min it'd pick signal back up and work again. I no for a fact its not me been in an area without 3G coverage because it happens at work and until this started happening i got a strong 3G signal there. It doesn't seem too switch too edge either any more. Its set too GSM/WCDMA prefered. I'm on 02.
Anyone else have similar problems or any clues on what the problem it.
Cheers
Ever since I got a replacement phone Ive had this issue- while on the Sprint network my signal will randomly go from full to nothing at all. Yet when I use roam control to go into roaming, the signal always stays at full strength
The other thing I noticed is that when I dial into the 3282 menu, someone elses username is there instead of mine. When I run connectbot and use getprop, no MSL # is there either
Anyone know whats going on with the phone and if this can be fixed?
getprop ril.MSL
It is filtered from just getprop.
My signal has always done that.
Updated profile may fix the user name?

Thanks that command did the trick to get the msl- I was able to go in and manually change the username now.
Is there any settings in the data menu to improve the signal? Its almost like its jumping back and forth between a good and bad tower?
Not that I know of. That is what I suspect is the case with me as I have about 3 towers that are surrounding me from various sides and I think it is hopping between them... not sure there is anything to do for it but I haven't really seen any ill effects from it.

The weird thing is it never used to do this before when I first got the phone. When I was in the same areas the signal bar was always full and would never drop. I wonder if its a tower issue or something they changed with an update.
Sometimes when people call me they say it goes straight to voicemail though which worries me
Could be the modem. Some people think el30 is not as good as ei22 or ec05. Maybe try some others.
For calls calls going to vm, that can happen if you are using data in a 1x area. Also can happen if you have accidentally switched on ddtm in call settings.

This is going to be plain and a tad bit retarded but a solution is WiFi, as far 3G and 4G mine has always done this but i can testify that in my house i used to get ****ty service like 0 to 1 bar when i was on EC05 i switched EL30 now to FB15 and say much more improvement more consistent to 3-4 bars.
PRL updates could help if you roam around there. newest as of today is 60685
I've been having this problem too for about two months now. But as you said roaming works fine so I just assume it's a sprint tower issue and force roam whenever I'm on wifi.
I have had this issue for a year or so... started a while after I first rooted.
You can hold my epic in one hand, my wife's epic in the other... her bars stay steady, maybe fluctuate between 2 or 3 bars occasionally... mine randomly and erratically jump from 2 or 3 to nothing, stay there for 30 seconds or so... and jump back up.
While its annoying and distracting, I've never had a problem with dropping calls or losing data. I even took the phone apart to make sure the antenna had not come loose. Problem persisted over several roms and several modem Odin flashes, just won't go away!
Mine does the same, it'll have full bars, drop down to nothing, but my 3g/4g still work fine (off wifi)... i just ignore the signal bars because most of the time my data still works, albeit a tad slow.
Currently running AllianceROM 4.4.2 on my Note 3 - For the longest time I was on straight-talk service, and after a while I kept having issues with crappy signal strength, Slow internet speeds and general reliability issues - Well, I went back to Verizon just yesterday and it seems to be worse. I've got 2 maybe 3 bars of service at my house, where as everyone else in my house (On Verizon, but with iPhone 4s, and iPhone 5) getting 4+ bars and 4G LTE. I sometimes get my LTE, but other times it is just 3G.
Sometimes my service will drop out completely, I won't have a signal at all..It comes back after a few moments though.
So I am wondering if this is a hardware issue, or issue with something on the ROM? Maybe I need to reset my phone, or upgrade the modem?
Also - My text messages are coming in strange orders. I will send one, Get a reply... But the reply will be above what I sent to them before, saying it was received an HOUR ago. Even though I just got it. Or it will receive twice, and one reply will be an hour ago, and the other will be current. I've cleared all data settings in my messaging app, and checked / changed my automatic time / time-zone settings.
Any ideas?
Hello, First time poster, and quite frankly a noob at a lot of this. Here's my issue, i have a at&t Samsung Galaxy S4 that i recieved from a family member that was stuck in a serious boot loop. Only way i could get it to come back was to flash the stock firmware, which worked excellent....now my issue, it seems like about 98% of the time i have the "No Service" icon up top. I got the phone locked through at&t but have since unlocked it to use on Straight talk, as thats what i was originally advised to do by an at&t member (turns out I didnt even need to do this in the first place as ST is just using the at&t towers as a reseller). Unlocked phone, still no service. I had ST previously in a Galaxy S2 in my current location and service was superb, so i know its not a carrier issue. Is it possible that when i flashed stock rom, that i missed something? I checked around and it seems like my modem is updated to the latest setting. When i switched it to ST after about 30 minutes the signal popped up and it seems like as soon as it showed up, it was gone again. Since that point i've been able to make 1 call (I activated ST about 4 days ago) and that call was today, with only 1 bar of reception. Shortly after that call the signal dropped completely again. I am at a complete loss as to why it refuses to get any reception. I was thinking maybe the modem needs to be updated, but the wifi works perfect, and the reception seems to show up (just as 1 little bar) rarely. Anyone have any ideas?
Also, as a little side note, i have done a hard reset a few times and to no avail at fixing the issue. I assume since at certain times i do get the little "1 bar" connection that its not a hardware issue but a software issue thats withholding the phone from reaching potential reception. Any help would work wonders as i've paid the $60 for the BYOP Straight talk.
Which firmware did you flash as the latest firmware is 5.01 and there is no stock rom from att for this version.

If your wifi is working perfect, then modem is not your problem. I have never used Straighttalk but you mentioned that ST is using the AT&T towers so there might be a problem in your simcard registration. Call the ST customer service, tell them your problem and ask them to reprogram your simcard with your phone IMEI. See that would solve your problem.
I was just wondering if anyone else has problems with their LTE dropping to 3G out of the blue. This happens when I am at home in a really strong LTE area. My wife's Nexus 6 doesn't do this, it stays in LTE. This only seems to happen to me when I am at home.
I am running the latest PN ROM, latest vendor and gapps, and I have tried numerous kernels. Both my wife and I are using the Verizon sim through Straight Talk.
Thanks for any help or ideas you might have.

I've made a post that mentioned this. There is a issue affecting only the Nexus 6p Phones. Google supposedly fixed the issue. Although Some seems are still having issues. Apparently it's stemming from the GPS. They have a workaround that's helping some. Have your carrier clear your location, disable your GPS, Reboot phone. Uninstall updates for Google connectivity services, and try to update it. And again reboot.
I continued having issues even though they fixed it, so I went cleared out system reflashed stock images, rebooted, via mskip toolkit. Been running pure stock except root, and been working fantastic with no issue. Hope this answers your question. Good Luck!
This has happened to me like... Once or twice since I've owned my 6P (~7 months) on Verizon (Non-MVNO VZW). Flopping airplane mode, Forcing the modem to reassociate would get it to jump back on LTE. The issue I've had more frequently (20-30 times since purchase) is the phone just falling off all data completely.
If VZW LTE coverage in your area is good (It's insane here in Florida) I'd recommend trying forcing LTE only.
Dial *#*#4636#*#* from the phone dialer. Then under the "Phone Information" menu. Hit the drop down that should currently say "LTE/CDMA/UMTS Auto (PRL)" and set it to LTE.
This is going to cause one of two things.
1. It'll fix your problem, Meaning it was actually some kind of provisioning/priority issue. Your phone for some reason couldn't hang on LTE, So it fell back to 3G to maintain connectivity. Even though it would've worked if it would've tried LTE again.
2. You'll still fall off LTE. But this time, Instead of falling to 3G, It'll disconnect completely.
If it ends up being #1, I'd try swapping SIM's with your wife for a day or so, Just to see if it follows the phone or the sim card.
Just started having this issue yesterday.
Before that almost never.
I also just upgraded to the August security path.
Well my calls dropped out 3 times, On Oputs network Here in Austrlia and i was on 3G and good signal, Lastest Pacth and Stock anroid.
