Kit Kat (Stock) Data issues - T-Mobile Samsung Galaxy Note 3

My phone seems to do this all too often on a daily basis. I check that I have no received emails, tweets, facebook notifications, etc. The problem is my data uplink arrow keeps flashing and it hangs there. This is usually remedied by putting my phone in Airplane mode and switching back it usually works but there have been times when I have empty bars with no data nothing, but it can be fixed by switching mobile network types from WCDA/GSM back to LTE. Anyway this can be fixed, or this actually a Kit Kat issue with the Note 3?
I'm on Stock Kit Kat Unrooted (unfortunately) because I updated before wanting to root and now I don't want to trip KNOX. I have also run a factory reset on my phone (through the bootloader) but it didn't fix the problem.
Is anybody else having this trouble with their Note 3?

I have this issue too. I'm rooted on Darthstalker v6. It happens daily. I just toggle airplane mode on and off and wait ten seconds. I've reinstalled this rom twice and the issue is still there. Hopefully someone can help.

Same issue here! Stock, unrooted. Must be a kit kat issue, I don't remember having it on jelly bean.
Anyone else with the same issue? Chime in

Yup.....been noticing this happen too.....was hoping it was a tower issue soon to be resolved....starting to not sound that way....blah
P.S just started happening (or me noticing it) in the last 2 or so weeks

It's a known bug in android 4.4.2. The new update 4.4.3 has a frequent data connection dropout fix in the change log. Hopefully we get some leak or something for it soon. Now that the s5 is out.

I didn't notice the data drop out until I tried a KitKat rom. When I restored back to the jellybean rom I was using the data drop out continued. So I ended up wiping and flashing the same jellybean rom and still notice the data drop outs.

I have the same issue from the last 4.4.2 update, when the phone is in standby for long time the data connection drop out, or time in time the phone scan the network and some time back to normal after some second or keep scanning and need reboot. when I check the network mode I found all option unselected, I select lte mode and the phone do not respond and have to reboot. I reinstalled 4.4.2 with kie and Odin but same issue . Samsung representative told me that the issue is from T-Mobile , that the phone is ok, and T-Mobile told me that the issue coming with the update from Samsung and affected to note 3 and s4. Who has the fault? my temporal free solution until the next update was replace the sim card in the T-Mobile store. I did yesterday and until now the phone have been ok with the data connection up all time. when it scan the network back to normal with not data drop out.
Last thing, go to wifi - advance option and I put disable (keep wifi on during sleep) and (always allow scanning) maybe these can avoid the scan the network time to time.

[Q] need to reboot or toggle airplane mode to regain connection

Hello,
I am running into an issue where I will lose connection after coming off wifi and it seems 4G/3G is not picking up. I must either reboot my phone or toggle airplane mode to regain signal. I've been searching around and I don't think I've found any thread similar...or it's hard for me to pin one down using search terms.
I'm running paranoid 2.16 and lean kernel. Gonna try and flash a radio and see if that helps...but if anybody can point me in the right direction or suggest a few things, I would greatly appreciate it.
Thanks in advance!
Lte or gsm version? Apparently the lte version has reception issues in general.
I used to take the subway to work. When coming out of the train, after losing service while underground, I would on rare occasion have no service while above ground in an area where coverage existed.
This bug existed on every Samsung smartphone I've ever owned (sch-r720 admire, t989 Hercules, and yes the i9250). I'm convinced it must be an android bug.

I'm stock (rooted)/GSM and I'm having this issue since 4.1.2. 4.1.1 was very stable for me. Today it lost it's connection completely to T-Mobile twice, where the status was always connecting even though I had 3 or 4 bars. Additionally, airplane mode would not engage (no symbol in menu) and could not be unselected from the power menu. Only way to fix it for me was to reboot the phone.
Additionally, I received a call today and the phone froze. I could interact with it barely, but couldn't switch apps or get out of the completely black phone screen. I had to unlock the phone to even see anything. After I missed the call, which rang for a long time (still no idea who it was - no logs and T-Mobile only lists connected calls), the screen would not come back on and I had to do a battery pull.
I'm about ready to just say F*** it and reinstall 4.1.1 stock back on this thing. I want my old phone back
Additional notes: The phone is encrypted due to my job requirements.
If restoring your backup cures the issues, then its baseband/radio/rom related. If not, the phone is damaged.
I had an sgs2 t989 which one day decided to lose its data connection. It constantly tried to sync and couldn't. Voice and text worked, but it couldn't get data (even edge). Changing roms didnt fix the issue and I had to exchange it in store.

I have this problem too sometimes.. CM10 M1, franco kernel. GSM nexus in Australia
I have a tasker task set up to cycle Airplane mode..
Freaking annoying.. always seems to happen when at the worst times..
I also had this behavior on my old i9020t nexus s to be honest..

"loosing" 3G on 4.3 Toro

So i was wondering if anyone else is having this issue.
for reference, I am on VZW, with the 4.1.1 radios (as the updated 4.2 radios had me locked into 3G no matter what, at work)
and i ALWAYS do a complete wipe (data/cache/dalvik/system) between ROM flashes.
4.3 bootloader as well.
anyway, this has been an issue since 4.3 hit my device...anything from pure AOSP to CM builds.
when I am on 3G, the bars will go gray and i cannot pull down data at all. (and yes i know the difference between blue and gray bars, I'm saying ANYTHING will say "network not available" not just google apps)
toggling data on/off fixes the problem. I ususally run into this problem 2-3 times a day and it is ALWAYS on 3G.
its not a huge deal, just more annoying than anything else. just wondering if I am alone here. going to be giving the 4.2.2 radios another chance and see if that fixes things.
Having this exact issue...it's driving me nuts as well. At this point I believe I've tried every radio with no luck. Going to try jumping back to 4.2 soon to see if it solves the issue.
Me too
+1
I love how much fast my GNex is on 4.3, but I don't think I can deal with this data bull**** much longer. Frankly, I'm really getting tired of getting a new version of Android, being happy at first, then finding the HUGE bug that makes my phone a horror to use. WHY HAVE YOU FORSAKEN THINE VZW GNEX, GOOGLE!?!?
Just an update, as I updated my radios right around the time I updated to 4.3. I just switched back to CM 10.1 and all my data connection issues went away. That means it definitely has to do with 4.3 builds and not the radio firmware.

That's right, 4.3 sucks.

Edit build.prop and include this line:
ro.telephony.default_cdma_sub=0
Data issues are being reported on nearly every rom for the gnex. My data reconnect /switch went from about 60 - 90 secs to a reasonable 5-10. (don't forget to reboot to apply changes)

So happy I found this thread!
I'm having the SAME issue: GSM i9250 on Straight talk ATT sim (apn setting are updated and correct). Stock not rooted; been happening since 4.3 Update. From what I've read even folks on the N4 are having similar issues.
I've factory reset 3-4 times for testing purposes (back to "normal" for about an hour then those pesky gray bars and NO data on 3G/4G).
I have to do the airplane mode toggle every 1/2 hour if I'm really using the internet. Big pain in the ass!
I always rooted my devices in the past and haven't done the GNEX because I always felt stock was smooth enough for my purposes (quasi-work-phone and I need stability). If I have to deal with this bull-sh&% I'm probably gonna have to root and install a 4.2 ROM.
Any-whoo...thanks for letting me rant :^)
Hopefully "kit-kat" will help?
same issue its very annoying... did anyone find the fix ??

Is this a fix?
My issue seems to be on 4g as well. If the phone switches from wifi to 4g or if it goes from 4g to 3g and back to 4g it shows a connection with bars but never connects to data again.

[Q] Data and syncing turn off when screen is off.

After running on a stock ROM(but rooted /w TWRP), I decided that I wanted to install a custom ROM so that I could tether if needed. Well, big mistake. I wiped stock and accidentally wiped my stock backup when going to flash a custom ROM and so far I've tried XenonHD, Jedi X19, IllusionROM, and now I'm on a Stock-Tweaked. So far, every single ROM has caused massive delays in receiving SMS messages and syncs from stuff like gmail.
Data is definitely working, and i've tried both the epc.tmobile.com and fast.tmobile.com APNs but my phone keeps hanging when it trys to send some texts and, if I have texts "waiting" to be delivered to my phone, I only receive them once I turn on my phone screen or only if the screen is on. So what the hell is going on here?
I am not installing anything on the ROMs aside from what's coming with them. The issue presents itself immediately after I boot for the first time and set up gmail.
It seems that if I go to 4G/3G/2G mode only the issue doesn't persist. Or at least not as much. But then I can't use LTE! =/
I've tried multiple ROMs that were TW and multiple that were simply AOSP. So 4.1.2, and 4.3 roms. I even accidentally flashed a 4.2.2 AOKP ROM.(for the Note 2, of course). I am not back to the stock Odin recovery with a root injected stock image but i'm still suffering from the same problem =/. This really sucks. Is there a way to completely wipe EVERY trace of an older Android install off of the phone?
I haven't tried the total stock bare bones one yet because the mirror is so slow, it's currently at 641 / 895 MB downloading and has about an hour left. It's the 4.1.2 June release.
I'm attaching a logcat to this post as well, from when I had the screen on, locked it, turned the screen on, and unlocked the phone.
I just realized the logcat is about 58k lines long, so I'd start from the bottom and go up since that was the most recent phone activity of when I actually went through the motion described earlier.
Let me know what happens when you try the stock sw.

I had this problem is well. I had to call at T Mobile I told him I was getting long delays in my text messaging, yes I know you're not getting delays it's only happen to you when your phone is in sleep mode. I told him I already did all the normal stuff to correct the problem. they reset their network connection. That fixed it for me. Hopefully your problem is that simple.

[Q] update modem/firmware/kernel to fix data issues?

Since I started working full time in my new career I haven't had time to keep up with the changes. Can I get someone in the know to help me out with this?
I remember reading that KitKat was known to have data issues. I have the following:
T-Mobile model SM-N900T
4.4.2
N900TUVUCNB4
custom kernel: 3.4.84-leanKrnerl-hlte-2.2 (don't remember name, got it here)
stock rom modified
Problem is every once in a while I lose data connection even though it shows a 4G icon and several bars of service. I even had T-Mobile send me the signal booster, which is installed at my home and seems to be working, but same issue continues to happen. And if I turn on WiFi at that point, WiFi connects, but 4G icon doesn't go away, and I stay without data access even though I'm supposedly connected to WiFi.
As you can imagine, this is annoying. It happens at least once a day, sometimes multiple times. Then it goes back to normal.
I don't have the time to update fully to a new rom with new firmware and have to reinstall everything. Is there new modem/radio/firmware/kernel I can install over my existing installation and expect to see this issue go away? Or am I stuck with this until I change phones?
Thanks for your patience and helping me out with this.
Unfortunately its a common issue and there is no fix for it.
quick fix it to out your phone in airplane mode then out of it
Thanks, although that sucks to hear. Of all my Samsung devices (see sig + smart tv, blu-ray, sound bar, tablets) the Note III has by far been the buggiest. Both my wife and I have had buggy experiences and I'm rooted and she's fully stock. Not nearly as happy with this Note III as I was with the Note II, that's for sure.
Once again, thanks for taking the time to answer.

I too had network issues. My 4G would slow to a crawl or would become non responsive. It would take a reboot or airplane mode toggle to make 4G work for about an hour before it goes bad again.
I updated to the latest NF4 firmware and it has been running for the past 48 hours with no issues.
Speed is not much of an improvement. I get around 30mbps /22mbps in NYC. But data stability has increased to a great extent. I do get the occasional hiccups with data , but it resolves itself in about 10-15 seconds.
Hope this helps you
Rooted Note 3 with stock NF4 firmware / debloated
Updated to nf4 before bed last night so it's only been half a day but will post result later tonight when I get home where I usually experience this data issue to see if the new firmware makes a difference.
Update: so far so good. I've been home for several hours now and haven't gotten any data issues.
OK spoke to soon. 10 minutes after I posted my data stopped working. Had to toggle airplane mode.

Anyone experiencing constant Mobile Data Disconnect?

Hey guys, been a while. Anyway I had my HTC 10 replaced under warranty a month or so back. The replacement I go, I keep getting disconnected after a day or so. So what happens is I can use the phone and all, but Mobile Data appears to break, as if I disconnect WIFI Mobile Data shows Disconnected. ONly way to get it back online to to reboot the phone.
This has been happening more frequently, every day I am ending up having to reboot since I cannot send any text messages.
Any suggestions? Is this a common issue with HTC 10? I'm on Tmobile USA Network. I never had any issues before with other phone (M8, M7, iPhone), and signal is great.
Just started happening to me....Was fine until this week.. Tmobile user also...S-on Viper10 rom.
Yes. Was it after the recent update?
Btw, either turning mobile data off/on or airplane mode fixes it.
So it's from the recent update? It's happening more and more frequent to the point I keep restarting my phone multiple times in a day. Also, the Airplane mode on/off doesn't bring back the data back online, even turning mobile data on/off or even switching the network mode doe not help.
Btw, my HTC10 fully stock, non rooted.
OK a new update just came in for my phone. Ran it, and monitoring how it goes. i will update thread if that update fixes the issue.
It hasn't happened to me since 1.8 update. Using leedroid.

Looks like the update that was pushed yesterday by TMO US fixed the issue, as I have not encountered the issue yet after the update.
Scrap that. Issue reoccured, although not as frequently....
To fix this I had to go into developer options and checked keep data on.
