TMobile Network Signals dropiping randonly - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

Hi,
I received this replacement T-Mobile Galaxy Note 4 from Asurion yesterday and it is happening that T-Mobile network signals are dropping randomly and most of the time. I did not had this problem with my earlier note 4 which unfortunately I lost. I am not sure if this is hardware problem or some app is causing trouble although all the apps are same which were installed on my last note 4. Should I return this hand set and ask for replacement or there is some solution for this problem?
Thanks

Return

If the device is not rooted return it. If rooted maybe is a problem with baseband.

Did you check the date roaming option in networks. That solved my dropped call problem

Maybe doing work on Towers in your area? I had same issue, ended up being upgrading towers. My signal would randomly drop, go back up then drop again. This went on for several days before it was back to normal. T-Mobile didon't have clue till I demanded to talk to the highest department. Working fantastic now. My data speeds are just sick. Lightning fast. Thank You T-Mobile, Thank You John Legere.

Probably a issue with your APN

3G dropped.. not a reboot fix type drop, just won't come back drop..

Ok, So far I've been loving this phone, no hiccups, no reboots, no problems and loving the battery life.
I live in a 3G only area so I have the phone set to CDMA only all the time. Last night I was having a chat on Google Talk and my 3G dropped, I figured, meh, it's just gonna need a reboot or let it sit for a while to come back. Well it sure didn't.. that was 12 hours ago from posting this. I've tried every toggle known to man, reboots, etc.. Nothing will give me my 3G back. Can someone please help me to prevent from having to call Verizon and go through all the reboot your phone, return to factory settings crap. Then end up with a factory like-new phone when my phone isn't even a month old yet. Wifi is working fine here at work, but I need my 3G.
Mine is screwed today as well... If it takes a factory data reset, I'd just as soon do it on my own. Update to fix isn't due until November... Grrrrrrrrrrrrrrrr...
Anyone with any real solutions? All the reboots/battery pulls/airplane mode toggles have been performed.
Thanks!

If both of you are experiencing issues today it may be something as simple as a network issue.

I thought so, but other people with smartphones around here on verizon aren't experiencing any issues. So I've eliminated network issues as the problem here.
yeah i think must be a network issue
Yep, same here... I even have a guy in another department in the plant with a Bionic and his is working just fine while mine sits brainless. it's definitely not a network issue for mine. aCk!!!
A new SIM card later... DoH
I have been dropping data connections also and it takes awhile to come back on sometimes. Usually if swith from 3g to 4g and such it comes back but I am getting frustrated with it. Other than that I love it.
Yeah, I'm really getting sick of the dropped 3G too, I can't figure out a pattern to it either, just drops out of nowhere sometimes.
I am having the exact same issues......I have power cycled, done battery pull, etc. Does not seem to be a network issue as 3G can be working fine one minute, not working the next, then go back to working again 5 minutes later. The duration almost seems random in nature. Very frustrating. Other than that I love the phone.
Same as pretty much everyone else. Really intermittent data connection problems. Have gone through 3 handsets so far.

Isn't there a number that can be called that updates your phones tower info?
Just found it. Try dialing *228. Not sure if it does anything or not but I have been dropping 3g too. So far my signal is much stronger but time will tell.
I'm having the same problem, but only at work. The signal fluctuates almost constantly from 4g to 3g with 4bars, to no data connection. Outside I get a stable 4g connection. My T-Mobile phone had a stable but weak signal here.

I thought *228 doesn't work on LTE phones? Mine won't even make the call when I try it.

It doesn't look like its dialing out. However, I am getting a message that my verizion sim card has been updated. So far I have not lost service in places where I would frequently lose 3g. Could be a placebo effect though.
Alright guys here I go I should of posted this on a topic thread I started couple of weeks ago but whatever here it goes and i hope it helps... So I went through 2 hard resets and one new SIM and so far this is he only thing the worked. Called big red and got a level 2? Tech support and since then have had no problems going on couple weeks now... Didn't see anyone mention this in previous posts. go into settings> Battery and data management > make sure you have "background data" and "data enabled" both checked. Hope this helps has for me and i hope I'm not repeating this info

Did the hard resets and sim change do anything? I have looked at my data settings and both items you mentioned are enabled on my phone.
Well yes on the hard resets and questionable on Sim card but data was still lost Week.later again and this new trick has been working since I did the changes going on about 2 Weeks now

Mine dropped today, one week into using this phone. Could be a fluke, but here's what worked: toggled LTE back on (no 4g here), then rebooted. Viola! 3g immediately. I really hope this isn't a constant problem...

Bionic 3g/4g is not working (DROP) "FIX"
After searching around a few days for solution n test many apk and many many methods... Finally found the fix.
Just download "BionicTCP" from market (Play Store) (REQUIRES ROOT), and click on "Large TCP Buffers". It makes my Bionic xt875 3G/4G NO DROP AT ALL.

HALP! Signal problem or defective phone?

I'm not very familiar with this. I've have data (4g lte) connection issues for a while now with my m8.so much so that I'm considering going back to Capts fastboot recovery file just to wipe everything and start over. I'm constantly in a 4G area, but can't get it unless I switch to airplane mode and back. Even then it's short-lived in multiple known 4g areas.
Anyway, tried updating prl. Get an error 1012. But when connected to my airave no problem. Just wondering if that's good to update while hooked up to airave cause I can't in a data area.
Thanks
Don't forget the thanks button!
Ok no one has said anything lol
I've been reading and trying to research my problem. I thought I saw a thread on this same issue but haven't found it yet (hard juggling wife kids work & Android).
Anyway I've spoke with sprint and I just don't trust them.
Been watching my signal on net monitor and everytime I connect to am ehrpd tower my phone tries to connect to lte but apparently didn't want to and jumps down to 3g. I can get lte but has to be a lte tower. Not real knowledgeable yet in this stuff but I'm trying.
Currently on Viper
Firmware 1.54.401.5
Prl 51100

I'm having similar symptoms. I upgraded this past Monday from a Samsung S3 that had good LTE and CDMA voice inside my home (Plano, TX) and my new M8 cannot maintain any stable connection on the voice or data sides. Even at my workplace, I can only get a weak LTE/Spark connection and no voice. I've already worked with several techs and support people at Sprint throughout the week and even exchanged to another new M8 with no better success. I believe it has to do with the Spark (which is actually one of the LTE-Advanced features) and the CSFB (Circuit-Switched Fall Back) that allows us voice on the old CDMA network until VoLTE to rolled out. I am frustrated enough to turn it back in and just go back to using my old S3.
FWIW...

I have no problem with the voice. This is where it seems many are having problems. I'm trying to figure out if this phone is supposed to behave this way with ehrpd towers.

I've mentioned in a different thread that LTE for me is mostly stable, but it does get a little wonky on me. For example, one day at work the LTE will be strong and solid and the following day it drops out intermittently and toggles 3g on.
Probably a sprint issue, not an m8 issue
I had the same prob with my first M8. Could not got 4g until I switched airplane mode off/on. Took it back withing 14 days and got a new one. This one gets 4g/LTE now but have had to switch airplane mode a couple times. Also, my airave does not like this phone. Sometimes it will give it full signal and then other times 4g will be showing and I have no signal and miss calls. I called airave support and the solution they gave me was to switch to cdma when at home.
This is a known issue with the M8. Some people have had success with HTC replacing the defective phone. http://forums.androidcentral.com/htc-one-m8/390449-sprint-signal-issues.html
Yep, defective phone
I had terrible connection problems after buying a brand new phone! Ex: No service, Dropped calls every minute, No LTE, 3G was rare. Basically it was not even a phone! I had to ship mine back to HTC. This was after hours at the Sprint store, and many customer service chats with HTC reps. I also had to unroot my phone which was a huge hassle considering I just found out how to root it. After getting a new one, works fine.
Don't let them tell you it is a service problem if you are having the same symptoms. THIS IS A HARDWARE PROBLEM and HTC needs to fix your phone. Hope this helps

Almost full LTE bar+LTE signal booster and some calls not going through?

I've been stock, Dynamic Kat, Fire Kat you name it.
So long story short, I have little to no signal in my room (2/10 calls will go through) the rest will go to voicemail and won't even give me a notification someone called. I also don't get any data or extremely slow when I'm lucky
So I tried the T mobile LTE signal booster and I can finally get data on my phone at slow speeds of 3mbps or even goes to 1 sometimes (I get 8mbps in the living room)
So now I still get random voicemails from my job or friends, I don't know how often this happens but it does happen....I always see a random voicemail without my phone ringing Wierd thing is I get FULL LTE or 4G bars
I tried using wifi preferred for wifi calling and cell data preferred and still happens, I even reseted my APN by deleting it, turning it off and taking the battery out so the APN would reset (I also added 80 to one of the apn settings, seen a thread this would help with texting and receiving mms) Do you guys use ipv4 or ipv6?
. I never had a problem like this with AT&T do you guys have any idea what could be wrong?
I kept having this problem.. Long story short.. I swapped note 4s thru tmobile and no longer have that issue.. All I was getting was voice-mails and text messages sometimes from people that called letting me know they called

Data issue...

I've been having this really annoying issue where all of a sudden I just wont get a data connection even though there is a strong 4g signal. Any app that uses the internet will say there is a connection error, it just completely stops. I've been getting around it by having to turn on airplane mode and then turning it off. After I do that, everything starts connecting again, but it is insanely annoying. It seems to be getting more persistent, which is why I'm wondering if anyone else has experienced the same thing and if so, how did you fix it?
Thank you.
Oh and just in case, I'm running completely stock non rooted.
I've had the same problem the past few days. Don't know why & it happens fairly randomly. Only way to get around it is to connect to WiFi or turn data off/on.
Are you on KK or LP? Its happening to me on LP. I live in CO and its even worse closer to Denver I go.

I'm on Lollipop. I think it happened on KK as well but it's definitely happening way more now.
I'm on Lollipop. Just started having the issue a few days ago.
I'm in Atlanta, both my devices have sluggish Internet def not what I'm used to. I called into tech support twice, was told they are doing network moderization....yea ok

Having the same issue here in Atlanta was told it should be sorted out by today. I'm also using lollipop stock but rooted. In the meantime ive been forcing 4g by using the lte dialer since I've been having frequent changing to edge network since the update, but I'm still having issues with a strong 4g connection especially YouTube app.

Some serious hacking went on yesterday. I'm assuming some of the slowness was related. Many online services were slow and United Airlines was take down completely.

I have the same problem. I had it on my s5 too
T-mobile
from what i heard t mobile was doing some cleaning up of files or upgrades i called them since i was getting 3g.
I too have been seeing the same data issue. It could just be coincidental timing but within days of loading LP I started having the issue. Even flashed the ROM again in case it was a bad flash.
As stated in OP I toggle airplane mode to fix. Annoying for sure.
PopRocks v5
T-Mobile
Bump.
I have been having this issue too ever since upgrading to Lollipop. I've had it on 2 versions of Poprocks and I now it have while using Rapture. Extremely annoying.
I got around it by rebooting the phone. I did not think of airplane mode or data on/off, i'll give that a shot. I was actually thinking maybe it's an APN issue, but no one in here mentioned that. For what it's worth I live in Southern California.
This issue is really starting to annoy me. One thing I do with my phone is stream music while I'm driving, and now I'm having all kinds of issues once my phone drops off wifi & has to switch to data. My music just stops playing & I have to toggle airplane mode to fix the issue, which isn't fun/easy while driving. Plus, when I do that my phone doesn't reconnect to my car's bluetooth. Ugh! I sure hope this gets fixed soon.
As an update, months later and I still have data drops all the time. Really annoying and it has definitely soured me on the Note 4. First with the GPS issue I was having (that was only fixed after getting a replacement) and now this data issue.
They only doing this too trick us into getting the note 5.

After reading the new info on the Note 5, I'm not all that impressed. Don't get me wrong, it sounds like a good device, but I wasn't really impressed with the changes. I'm sure it'll still be a great phone, but I don't know if I'm willing to risk another year of the data issue. I may go with the new Nexus this year.
I've had this problem (5 bars, but can't even ping 8.8.8.8... but if I toggle data off & on, I instantly connect & usually get fast transfers) all the time (Fort Lauderdale area) for months, but it seems to have been particularly bad for the past few weeks.
Is this T-Mobile's fault? Or do Note 4s on other carriers (Sprint, Verizon, AT&T, etc) have the same problem?
My theory:
* The number of bars is determined mostly by the signal strength of the nearest tower
* The phone doesn't necessarily use the same tower for data that it uses for voice & SMS (in fact, when it's using HSPA+, it HAS to be simultaneously connected to two different towers).
* The modem firmware resists changing towers when there's an active data session unless it totally and completely loses sight of the tower it's currently using for data. I'm not sure whether it's the fault of Android or GSM network design, but data hand-offs seem to be "hard" rather than "soft", and always involve a connectivity break of at least a few seconds before the new one gets established.
* Thus, you can get into a situation (say, by driving a half mile or so) where the phone establishes a data connection with one tower, you drive *just* far enough away that it can still hear the original tower -- but can't actually complete a transmission without unrecoverable errors -- but voice & SMS messages go through the nearby tower. When you toggle data, it breaks the old data session, and establishes the new one from the strong nearby tower.
One thing that appears to have changed (in South Florida, at least) over the past few months: I always had problems with losing data connections while driving unless I disabled LTE, but NOW it appears to be doing the same thing even when GSM/WCDMA only is selected instead of GSM/WCDMA/LTE. It's like they figured out what was making LTE dysfunctional, then went out of their way to make HSPA equally dysfunctional.

[Q] t-mobile note4 with att sim not working on att microcell

My ATT microcell does not work with my t-mobile note 4, using my ATT sim.
Looking for anyone else in the same boat as me.
I purchased the t-mobile note 4 a few days ago to get back into playing with ROMs.
I put my ATT sim from my Galaxy s5 into my t-mobile not 4.
It is not working properly on ATT microcell.
The behavior is, signal goes 5 bars for a few minutes, then no signal and have to reboot phone to get signal.
I will call ATT today about it.
I searched this forum, and only found this thread which I replied to.
http://forum.xda-developers.com/note-4-tmobile/help/lte-t-mobile-note-4-att-service-t3002126/page4
I finished a chat with AT&T live chat, and they just suggested to check APN settings which were already correct. I ask the ATT support person if they had any notes in their database about customers having problem on ATT microcell with other carrier's unlocked devices, but the support person said they could not find anything. So I guess I will wait and see if anyone replies to this thread, but I might have to just sell this t-mobile note 4 and get an AT&T device. But I will keep the thread open.
Just some more info.
I found that if I unplug my microcell, I still had a lot of problems connecting to my nearest tower ( very weak signal, 2 bars, which is normal for where I live. ).
But after 15 minutes or so, the note 4 totally disconnects.
Have to reboot to get it to re-connect.
I'm running 5.1.1 by the way.
What I then found is a bit interesting, if I turn off my WiFi, forcing the device to use it's 4G LTE connection, my signal strength goes up to about 3 bars, and no more disconnects!
