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.

Well Sprint's speed has always been an issue for most of us. That is no surprise. I at least expect to to work AT ALL which apparently it is incapable of doing recently.

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:
Edit just re read your post, I have the same issues sometimes and as posted above toggling on and off typical works for me,, good luck
Also is your network set to
CDMA/LTE/EVDO? Just throwing out ideas

I get this issue all the time & I have to do a battery pull to get my phone working again. Anyone flash a new modem which fixes this? The SGS4 is 10x worse than my HTC EVO 3D was with this issue.

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.
I have a problem with my 6p where the signal just drops to nothing (Looking for service) and 3 or 4 seconds later it reconnects to a good LTE connection. The problem is not my connection as I live in a good area. I was rooted with xposed but for ****s and giggles I went back to complete stock and it is still happening.
I have reset the APN settings to no avail. Is this a thing that is known to this phone? Should I get a replacement? It started just recently it seems as I have had this phone since launch.
What sucks is, is that this phone is absolutely perfect (or was) and I dont want to get sent a phone with screen issues.
EDIT: I ended up getting an RMA and everything is hunky-dory.

What radio version are you on? You can flash a different version in fastboot and see if it helps.

Im on the newest one. Do I just extract it out of the 6.0 image file and just flash it over the top of the existing one?
I forgot to also mention that I tried getting a new SIM card from Verizon but that did not fix it either.

Yeah. Extract it and flash it over the top in fastboot.
Did you ever find a remedy for this problem? I'm having the same issues on t-mobile so its definitely not network or a similar related issue. Did flashing the radio from the 6.0.0 rom fix the issue? I already tried several different 6.0.1 radios and a radio from 7.0 but to no avail. I'm about to try it and if it doesn't work I'm getting rid of this phone.
I'm going to assume you mean you'll be on LTE for the longest time then all of a sudden signal completely drops then comes back on, but without the LTE signal showing near the bars, so you'll have to airplane mode, then switch mobile data on and off, then do a restart. If this is the case. That has been a documented CM13 issue for the longest time. I had the same issue with the HTC M8...

I am on LTE but as the OP said the signal randomly drops completely for 4-5 seconds them comes back LTE and all. I don't have to reboot or anything. This doesn't have to do with cm13 though, I've tried flashing back to full stock and I still have the problem there too.

I've managed to get a logcat at almost the exact time the signal drop happens, I had to put it in a Zip since the Txt document was too big for the thread. The drop happened in the last couple minutes. I'm hoping someone here with more experience than me can help me solve this issue. Thanks in advance.
Having the same issue on T-Mobile smh... it gets annoying at times!
Sent from my Nexus 6P using XDA-Developers mobile app
Same problem here. On Verizon
Anyone find a fix? I'm on the latest Android N Beta on Tmobile and still have the issue.
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)

Sometimes I'll lose signal only to have it reconnect immediately.
Here's a screen recording of it: https://youtu.be/v9skns6qntE
It all started last October 2016. My 6p is stock, rooted and I have been with Project Fi for over a year now without any issues until last Oct 2016. Out of the blue I loss my cell signal but only with T-mobile but not Sprint, nothing will bring it back until I reboot my 6P I can’t even make or receive a phone call and google Fi customer services was no help.
I updated to 7.1.1 in December’s update and all cleared up. I stop having my cell signal stopped dropping or when it does it would pick up the signal immediately, all seems good to go but, until yesterday. I loss my cell signal but this time it didn’t come back I had to reboot.
I have done some Mods with Google assistant and not much else, so I have no idea what my be causing this, hopefully Feb’s update will help.

Yea its Radio related (duh huh lol). I flashed the newest radio from Jan and same crap. The ONLY radio that works consistent and NEVER loses signal is the 03.61.

Does it change bands (or carriers) when coming back up? I don't use Project Fi (AT&T) but sometimes the phone switches bands when a stronger signal is available. Have you tried the LTE Discovery app? It shows not only the band and signal strength you are connected to, but all neighbor cells and their strength. You can also quickly reset the connection to grab the strongest cell tower. Might give you some additional information. I guess you've already tried the 03.79 radio from N4F26J, rather than 03.78 on N4F26I. You may also see whether or not you can duplicate the problem on a different (non-Fi) SIM.

I'm on Metro PCS which uses T-Mobile towers. I've tried everything already, I'm on my second 6p. I RMA'd the first one for this same reason. I've tried a new sim card. The only thing that works is using radio 2.50. Some people are saying radio 3.61 and 3.72 works. I've experienced drops with those radios although not as frequent. I suggest anyone with this issue report it here: https://code.google.com/p/android/issues/detail?id=232089

Yup mine does that, while walking around trying to catch pokemon, I'll get No Network. It'll come back after about 15-20 seconds. Happens often in Downtown San Diego. I usually just switch from Tmobile to Sprint when that happens. Though Sprint service is weaker...
When it happens, I notice on the Signal Info app that TMobile is jumping around between LTE, HSPA, HSDPA. 2G Edge, all within a few minutes.
I am on latest factory stock image.

Same problem with my Nexus 6P on Verizon. Cellular signal is lost and only restored by rebooting the phone. Happens 1-2 times daily. I'm on Android 7.0 build NBD91V.
So I had an interesting experience with the same thing. Was running a custom rom that is very close to stock and updated to the most recent security update. Shortly thereafter, my carrier connection would drop (didn't notice at first because if I was connected to WiFi, it would be hard to tell). Only a reboot of the phone would fix it, for often no more than an hour or 2. So I started by wiping the device. Then I went to a different custom rom. And then finally, I went back to stock using "flash-all.bat" from the factory image. But alas, the issue continued. The last thing I did, which seems to have resolved it so far (12+ hours without a disconnection), was to relock my bootloader. Just in case it helps someone else. Is it possible that the new radio + an unlocked bootloader is causing the issue?
I am it's so annoying! I've used so many Roms and it happens anyways. I've updated the radio and bootloader and still doesn't help. I'm on T-Mobile as well

For me it's band 4 I think.
Is anyone having this issue.
I upgraded to android 8.0 and no longer able to get any Verizon LTE service no matter what location I am in. I get frequent notifications stating I am Roaming and my phone is not rooted and the bootloader was locked, yet Android Pay Pop ups stating it cannot work on my 6p because my phone is either rooted or the bootloader is unlocked.
I flashed several different images to no avail.
Advice?

Reset Network settings reset, wipe cache partition. When you say you flashed images, do you mean sideloading OTAs.... or are you unlocked and using full images? Your post led me to believe you were getting erroneous messages about being rooted/unlocked (meaning you were not).

Tried it all.
I installed several full factory image versions, locked the boot-loader and then started up the phone. With the boot-loader locked and phone not rooted Android Pay still gave me the error that my phone is running a custom ROM, the boot-loader is unlocked or the phone is rooted.
I have also installed several OTA images and none of the problems I mentioned in my earlier post went away. The only way for me to get Android pay to work is to unlock the boot-loader and root the phone with magisk. However, I still get intermittent Roaming notifications, intermittent signal lost and no LTE whatsoever.
Today:
I called Google and and did 45mins of troubleshooting, the final thing we did was reset my phone and then the agent acted helpless when nothing resolved the issue.
I called Verizon did 30 minutes of troubleshooting with them, reset network setting about 100 times, turned off my phone so that they could re-provision on their end. Turned the phone on and got LTE signal for approximately 60seconds. Then it went back to 3G, then no signal and then the dreadful roaming notification every few minutes.
Are you using the stock recovery or TWRP? And when you installed factory image did you do it through your computer using flash all? Or did you just install the factory image? Personally what I would do if wipe everything out and use your computer to install the latest factory image using the flash all script. So you are completely stock then relock the bootloader. Then you should be completely up to date with modem bootloader recovery vendor and rom. Your lte issue sounds like a modem problem possibly. And the September security patch broke safety net check and therefore Android pay. That build ended in.017. there is a new one up that fixes those issues and I think also the issue with the phone choosing mobile data over WiFi when it should be choosing wifi over mobile. That build ends in.019. try installing that build like I said above. Good luck

I wiped DATA so there were no files on my phone.
Downloaded july,august,september factory images and flashed, locked bootloader and tested each image to no avail. I saw the build on the google forum for 019 so i flashed that as well and same sh:silly:t different day.
Last thing I did was to flash 7.1.1 and that did not resolved my problems. Got the OTA notification to install 8.0 hoping all my problems might disappear but they did not.
It has been an hour and LTE seems to be working again
I have a 5X on Project Fi and my 6P is on Verizon(the phone that is having problems).
As a last resort tonight I swapped SIM Cards and after a few minutes the Fi SIM in the 6P showed LTE service. (Maybe proof it was not the phone....??? who knows)
It took alot longer but my Verizon sim then showed LTE service on my 5X which is running Oreo btw. (Baffled at this point)
I placed the SIM cards back in their original phones and LTE is functional on both. On my 6P I enabled WIFI, downloaded data, toggled WIFI, rebooted, ran several speed test and the 6P still shows LTE and I haven't seen the dreadful roaming notification as of this message.
I guess problem solved. Now to install Magisk to get AP working.
Wow that is odd. The one thing I have noticed with 8.0 on my 6p on fi is sometimes I lose data when I'm out and the phone loses wifi and switches back to lte. I have to reset the phone to get lte back.
Thank you so much for posting this issue. My Nexus 6P was doing the same thing after 8.01 October security update. Tried everything, same as you listed. I found your post and recalled that during my initial setup I had to put my wife's Verizon SIM into the 6P due to the same issue occurring. I tried it again this time but it failed, issue persisted. So, based on your post, I got a Project Fi SIM for $30 (1 month) and just tried it again. Powered down, put in Fi SIM, power on, activated Fi (with new phone # for new line... will be cancelled if needed...), and got LTE without issues over Project Fi. Then, I did Network Settings reset, reboot, and powered back up. No issues with Fi.
So, to the point now. I put the Verizon SIM back in the 6P and BAM, full LTE, no issues. Whatever the non-Verizon SIM does to the phone internal settings I have no idea, but I can tell you that it was not a fluke that your process worked. The exact same thing worked for me.
Hope this helps anyone else with the same issue - you need to install a non-Verizon SIM, get LTE going, and then put the Verizon SIM back in.
Thanks again.

Just my 2 centers here for anyone else in this quagmire...
I had same issue. I've got a Nexus 6p on which I dirty flashed an 8.1 update of ABC Rom over an earlier 8.1 version of ABC Rom. After that, the issues began. At boot, I'd be on 3g and if I toggled airplane mode off and then on, I could get LTE for about 10 seconds. However, it would then drop back to 3g. I tried everything, as is stated above: revert to stock, older radio images, different SIM... nothing worked. I read about people manually configuring their APNs. However, I've got a Verizon SIM, so that option was gone.
Anyway, after reading this post, I got the idea that I might be able to mimic the solution without buying a Project Fi SIM that I don't want.
Here's what I did:
Open the Phone's Testing Settings by dialing: *#*#4636#*#*
Tap "Phone Information"
Scroll down and set the "VoLTE Provisioned" toggle to the "on" position.
Then, toggle airplane mode on and off.
Profit!
I'm not sure if this solution has any parallels to the solution that uses a project Fi SIM for a brief moment. However, I speculate that it may.
At any rate, I hope this helps someone else with this issue.
UPDATE:
It turns out this method is more of a work around at best. At first I noticed that I had to toggle airplane mode once after a reboot. That didn't seem too difficult. However, I then discovered that I could no longer make calls. Switching the VoLTE Provisioned toggle back off fixes the calling issue, but puts me back on 3G.
Uggg.

Hey is ur 6p still running well with LTE? I did that with a att SIM card and my 6p read as a att SIM so I then put my Verizon Sim back in and it read Verizon LTE but then after like half an hour it changed back to roaming and 3g. I went to Verizon to get a new sim card but that didn't do any help at all. I would like ur feedback if possible. Thank you

Hello. I have not had any issues with the 6P since posting this. I honestly can't explain why the method posted earlier works, there does not seem to be a visible change in the user accessible settings.... so i don't know if i can help you any further from a technical standpoint. I'm not sure why the Verizon SIM didn't fix it the 2nd time, in my case. Something to do with the internal calibration of the LTE antenna (i'm guessing).
If you're willing to go this far, a factory reset of the phone, then ATT SIM might be an option. I HAVE NO IDEA IF THIS WILL WORK, so take that advice with 'a grain of salt'. Something to consider if you don't mind resetting the phone but don't/can't get a Fi account.
I can say that it was worth the $30 to me for a Fi account since it fixed it, but maybe more importantly the knowledge that if it happens AGAIN I should be able to fix it.
I know that wasn't super helpful but that's been my experience since the post.
(unrelated, but since you're a 6P user you may find helpful, I had the dreaded early battery shut down and it got so bad it almost bricked my phone. I got a new battery by sending it to Huawei customer service and it works like a champ now. Better than when it was brand new, from a battery standpoint.)

Tea I bought a new battery on eBay for 10 and got it replaced and it's running awesome. Are you on a custom rom? Just wondering what else I can try to fix this. It's weird while on the att it worked fine with LTE. I'm thinking about getting a fi acct thought

I had this same exact issue... I'm on Verizon and I was running FireHound ROM, which I loved btw, but every time I restarted the phone/toggled airplane LTE would pop up for 30 seconds and I would be stuck on 3G. Huge bummer but I found this to be an issue on every current custom ROM. Defeated and abused I ended up returning to 100% stock, unrooted and locked bootloader, full LTE capabilities now. I did end up buying a new SIM which helped with some of the connectivity issues I was having before granted my original sim was cut twice and I had it for many many years. Try going 100% back to stock, replace your SIM(most places cost about $10) and you should be good to go. I can only chalk this up to be an issue with source provided to developers but I'm not sure where the discrepancy lies for DEVS that isn't consistent with a stock instal...
Tried all these ROMs:
FireHound
ABC
Resurrection Remix
DARK ROM
Cortex - Uneffected by the LTE issue but is a dead ROM as of now and is on a different vendor.
