Hi guys, just flashed a new rom (jm7).. everything went ok.. but when I rebooted I notice that I get just about no signal in areas where I used to before get full bars.
Tried going back to other rom's but no luck, I still continuously get a poor signal. One thing I did notice is that right after boot the signal slowly goes to 5 bars (even in areas with bad signal) and then slowly goes down to 0-1. This same instance happens when I place a phone call as well.
Any ideas? I can barely use data when this is going on as well.
Try going into mobile networks and network operators and see if there's a second option for your network. You might be connected to a weather signal. It's under wireless settings. Happened to me.

Are you sure that your network operator make some not some work on cell bt in your area? One time i have too like you bad and wrong signal, and make all with my galaxy, reboot,recovery, signal refresh app, APN point new entered, but still problem. After all, I call my operater and they say me:" Sorry , we make same work on cell base station in area your city !!! Sorry for bad signal, we busy to make repair speedy !!! "
Best regards
Sorry double post
Thanks for the responses... no go sadly.. tried switching the 3 different "bell" networks and only 1 allowed me to connect. As for signal str in area, a friend who has the same network has 4 full, while i only get 1
I've tried reformatting/reflashing/reseting and nothing has worked.. what am i missing?

OK does this phone actually show anything other than 4g?
I am in a 3g area and I have not ever seen anything but the 4g icon.. Unless I put it in gsm only mode. But on auto or Wcdma mode it stays on the 4g icon.
Also it seems like I have issues with the Internet staying connected even when I have signal.
Also it seems like when I leave my screen off and turn it on the signal is higher than normal but goes down within a few seconds.
Anyone else notice this?

I am having the EXACT same issues. But, I am in a 4G area. Of course I got throttled by blowing through my 5G limit in a week--damn these new toys and massively restrictive internet access at work (financial industry). So now I am on edge for a while; but with the 4G icon up, I cannot hold a data connection at all. It goes on for a few seconds or such, then nothing. The upload icon is always on, but no download. I have to force GSM mode to maintain any sort of connection. The "Auto GSM/Wcdma" does not switch modes efficiently. I think it is continually checking for a 4G connection, thus resetting the 3G/Edge connection it is making. Very frustrating. . . I am hoping someone with make a Auto/4G/3G/Edge toggle so I can drop it on the homescreen rather than digging down for it.
Same thing here. Always on 4g and my wifi is spotty like the first poster. What's the deal?

5gb in one week?? That's insane usage u might need the 10gb option..
The 3g 4g network is the same network.. some towers aren't updated and some phones don't get 4g speeds but that's why it always says 4g

Anyone have an issue with their phone randomly dropping Wifi/Cell connections? Sometimes it doesn't happen for a day or two sometimes it happens 3 times in 5 minutes.
Starting to think my phone is defective...
If you are on a custom rom try going back to stock and see if it's the same. If stock try to update profile

I've tried that and it's still dropping... Would PRL/Profile also effect my Wifi connection? All data connections drop.

I'm having the same issue with Wifi. It'll still show as being "connected", but there won't be any data coming through. I'll have to toggle Wifi on/off to get it back. Sometimes it'll work for a couple of hours before having the data issue again, sometimes less than a minute.
I'm on stock, rooted.

Connections optimizer is off for me too - My phone shows a clear signal disconnect and reconnect (The wifi bars/3g symbol disappears completely) during this time all data connections fails - including texts. This is happening when I'm staying in one area so it couldn't be a tower reconnection issue.
I'm going to try taking my phone into a sprint store today to see what they say.

Ah, it sounds like our issues may be different then. My issue is solely with Wi-Fi (haven't noticed issues with 3G). When it happens for me the Wi-Fi icon in the status bar doesn't change, I just can't connect to anything.

Yup, same here. Seems like the 3G radio does the same thing, but not necessarily at the same time as the WIFI. At first I thought is was only the WIFI too, but 3G is affected, though not to as severe a degree. My WIFI was actually disconnecting and failing to reconnect. Turning off connection manager made no difference. I did however notice that the WIFI at my work (WEP encryption) never seemed to do this (at least I didn't notice), so I changed my home network WPA to WEP and sure enough, it stays connected. Was still failing to load occasionally, so I went even further and changed the router to a single channel rather than "Auto" and set it to "N Only" (due to having a similar problem with a laptop I used to have, with a similar solution). Problem fixed. I'm using an Amped R10000 just FYI, not sure if it matters. Very annoying, and given the number of occurances being sufficient to start a thread, I'm assuming this is a common issue and will hopefully be fixed by a firmware update. In the meantime, we should probably all start calling Sprint daily and complaining. Maybe they're not even aware of it. Probably not enough of these phones in circulation yet for them to worry about it.
Mine will do this from time to time. Stock not rooted. I will have full 3g bars and full wifi bars and my data will just hang. If I turn off wifi everything works again. Some times when I load a game that has to connect to Facebook to play against friends I have to close the app/game, remove it from memory and reload it to get the data to work. Same thing for Pandora. It will load a song to 2% and hang until I stop wifi or reboot the phone. It's not an everyday thing but some days are worse then others.

"Good to see" from the perspective I thought it was just me. Things described by others happening to me as well. Personally, I find I like the wifi/3g auto connectivity feature - when it works. Got my SGNII on Thurs last week, and connected to wifi at work on Friday no issues. This morning, the Note picked up my work wifi without a hitch.
At home, over the weekend, I was getting spotty connection, sometimes no connection to my wifi. (Disclaimer - I have my main wifi @ N/5ghz. An access point was added with wireless G via an old Netgear router-turned-AP.) After several attempts of moving the AP from one cat6 jack to another, I finally moved it to my main level. Oddly enough, so far, so good. Certainly possible the router's radio is pooping out.
What I notice happen with connection issues though seem related to the Note seeing my wireless G, trying to connect, but unable to do so until/unless I reboot my phone. After moving to the new location/jack, everything seems to work OK now (knock on wood).
Having said that... I also think the 3g radio (HW or SW?) is a bit wonky, as my old HTC Hero seemed to have more bars at home, IIRC. Whatever it is, just seems a bit lacking, IMHO.
Sprint is updating to LTE in many markets ive noticed my 3G drops says preparing networks and reestablishes the connection to 3G. I live in Fort Wayne and issue the permits for the tower co-locates and they are close to going live with LTE here so I know thats my problem. I can live with the flakiness for a few more days. I have not had issues with WIFI drops at home.

The same thing has been happening to me here on Long Island. 3g drops and reconnects. Sometimes it doesn't and a reboot fixes it. I also notice after the disconnect and reconnect it states my PRL is unknown. I have done a PRL update many times, a Profile Update, a RTN reset, and a factory reset. This happens on the stock rom and any custom ROM. It's driving me insane!
hmm maybe mobile settings?
Ive found LTE/CDMA setting to be not so good.
Its providing me eHRPD signal which is stop and go web browsing is murder.
CDMA only setting is providing Rev A signal fast web browsing
Sigh, so it seems as if you guys are losing wifi/3g....is it affecting voice radios or LOS/dropped calls?

I haven't been on the phone when it's happened so I couldn't tell you - Nothing like the LOS on the E4GT. When the data connection does cut out it immediately reconnects. Doesn't really impair the functionality of the phone but it happens enough to be annoying. With a 300$ price tag I expect my device to be without defect.

I'm not having LOS /dropped calls just data creep with LTE/Cdma setting enabled.
Speed test show same data speed numbers as CDMA only setting but when browsing data arrows tend to pause more making for slower page upload with LTE/CDMA setting enabled.
According to Sprint store tech such performance is common with that setting.

I am on CDMA only. I should have mentioned that in my first post. This does affect phone calls too as ill be on the phone and the call will drop and the "out of service area" message comes up. It doesnt matter if I'm on my Airave or not. I tried different prls which doesn't seem to make a difference. I am starting to think there is something wrong with the phone as my girlfriends S3 doesn't do this. Maybe Samsung will release some sort of update to fix this issue.

I made the change back to CDMA only mode this morning and it has solved my WiFi issues as well. I was also struggling getting a GPS lock with LTE enabled. GPS toolkit would show 20/21 satellites found but it would never get a lock. After the reboot back into CDMA mode it locked in 5 seconds.

Hey I'm a 1st to T-Mobile i'm testing it out before I switch all my lines from Verizon. The question I have is that both the Note II and the GS3 that I have seem to drop the Wifi calling feature randomly. I thought at 1st it may have been some sort of power saving option but it seems to happen in frequently. (Doesnt matter if I'm close to the Router or not)
Is this common? Or am I the only one that has had this happen?
Thanks for any input!

I'm not sure what you mean by turning the App off? When turning the WIFI calling app off does that not mean you are unable to use the feature?? LOL- I have to have this as I have zero reception at my home.

mine goes on and off on both my new note 2 and my wife's new galaxy s3. really aggravating. worse on my phone, when in wifi calling, it only answered calls like 1 out of every 10 times, otherwise they went to voicemail. I took the sim out of mine, then put it back in and pushed it in and out and in the holder a few times and now it seems to receive calls in wifi mode but still always in and out and error to connect and such.
My experience with Wifi-Calling has been nothing but troublesome. It's really not reliable at all, sometimes calls comes through sometimes don't.. and when it does come through I can hear the caller but caller cannot hear me. This is quite common problem with wifi-calling and i given up.
If you get even a 1bar of reception near by the window, I suggest calling T-Mobile and getting their Cel-Fi device (Free of charge but has to return when you leave T-Mobile). 1~2 bar by the window will give you full 4bar reception throughout the house on 4G. Only requirement is that you must be living in single house, can't ship out to house that are connected by or close by. I live in townhouse and I just told them I live in single house and got the device in 3 days. =)
Wi-Fi calling is a disaster. For me, incoming audio drops constantly, but the party I am calling can hear me fine. On other occasions, the call will just randomly drop. Came from a Sensation where Wi-Fi calling was perfect. There does not seem to be any resolution... I have spent hours talking to tech support and they have replaced the device with no improvement. I have also had my ISP out and they have verified that my connection is fine. I have even changed the router out... same issues.
With my wifi calling, as soon as I turn kt kn my bars at home would drop where I would hardly get any service. As soon as I turn wifi calling off I magically get bars. So I leave it off and now I get bars pretty much everywhere I go....almost

With wifi calling on, it's suppose to drop signal bars to nothing. You have to go by the wifi bars instead.
Wifi also greatly depends on your network conditions. Cause I have the same problem but it doesnt happen to me that often after some tweaking.
Wifi Issue
I have that problem quite a bit but the signal strength on my router is good. Yesterday i had my internet company reset the cable modem and my wifi problems have decreased a lot but it is still happing. It has to deal with the wifi certificate problems on the Note 2 (Samsung). It is the same problem that I had on the GS3.
Oh well

Uhh, that's the point of wifi calling, to make calls over WiFi and disable your cellular radio. If you turn on Wifi Calling, you should get a blue phone icon on the top left and your "bars" should drop to nothing as your phone turns off the cellular radio. You can still make/recieve calls/sms/mms.
I've been getting an ER01 error lately with invalid certificate, but it seems to be a T-Mobile backend problem? It happens, about 10% of the time and only on my school's network (I have a feeling, it might have to do with the sign in process there).Otherwise, it works well at my apartment.

i get that certificate problem at my house, not too much anymore, but I still see it. and the wifi calling does drop in and out at various times. not a huge deal for me, but the average person wouldn't deal with that.

I've been noticing more & more problems with my service in the last two months. I called T-Mobile to fix it and whatever they did seemed to only help a little. I get times where I get frequent ER01 errors with WiFi & duplicated text messages (same text message gets received by my phone 2-3 times) for an hour or two. I used to also get errors sending texts around that time, but that appears to have gotten better.
Someone else mentioned Uverse, and my WiFi calling problems are at home & work, both of which have AT&T for internet... When I switched from their DSL to Uverse I expected less problems, but got more.

Seems to be a problem that a lot of people are experiencing. Just did a quick Google search and some indication points to a possible T-Mobile back-end problem. I wonder if i call up T-Mobile and ask for wifi calling to be explicitly added to my plan if that'll change anything.
Ive had my note 2 now for about a month now and the phone itself has been great. During the first week I experienced horrible signal but that has all stopped recently. I now get 4g everywhere I go around my home and work.
But.. one problem persists. Missing missed call notifications and delayed voice mails. This has been going on since I got the phone and I though it was only a wifi calling bug until today.
Multiple people have called me and left a voice mail which I will only receive once I use my phone. Ie: text/make a call. No missed call notification shows up but I will receive texts and voicemails once I actively use my phone.
I have done tests with wifi calling where my phone would be charging for a few hours and a call would go straight to voicemail. Also pinging my phone yields a 1k+ms ping response and then normal 50ms which leads me to beleive the phone goes into some sort of sleep state and has to be actively on the network to receive any call or text. I thought it was just wifi calling but now its happening without being connected to wifi.
Does anyone have any information on this type of problem?

I had the issues you described with wifi calling. It was so unreliable that I stopped using it. On the regular cell connection I no longer miss calls.
I wish using regular cell was reliable as the coverage is great in my area. But after yesterday's problem I can't trust it anymore.
I'm back to using wifi calling and im using an app called wake lock to keep the wifi connected, as the normal no sleep when wifi setting doesn't work in the settings.
It has been 12 hours and the wifi calling icon hasn't disappeared. I've received emails and texts as well. Hopefully this can be a permanent at home solution. I wonder what causes the cell network to just drop and stay unconnected while the phones on lock though.

Are you using ant task killers or battery saving apps? They can turn off your data and so many other processes, they do more harm than good.
Sent from my SAMSUNG-SGH-T889 using xda premium
I have no battery saving apps, all i use is the stock task manager for ending tasks.
UPDATE:
WiFi calling with wake lock seemed to work most of the day. I received many texts and calls from at least 5 different people over the coarse of the day. But then... I go in my garage and lose wifi signal and the phone doesn't connect to a tower and i miss someone trying to call me. Same deal.. no missed call notification and they said it just goes straight to VM without ringing. I write it off as not a big deal as long as the rest of my house wifi calling allows me to miss nothing.
I sleep for a few hours and i wake up and hit my lock screen. The screen flashes on and it shows the WiFi calling symbol.. then lags and flashes to it being gone. I then use my house phone to call it and of course.. no ringing.. straight to VM. I have also received no emails/texts during this time.
I open the battery usage and during the last 15 hours or so there are small increments of signal loss. The whole bar is yellow which isnt great but should still work. But there are small slivers missing completely, and they are identical to the WiFi usage as well. Both show the same 0 signal at the same time.
I'm at my wits end with this problem.. i have tried just about everything from factory reset, SIM reset, using WiFi calling on both my router bands, using settings to keep WiFi on when phones charging. The problem persists on 4g and WIFI. Currently I'm set to GSM only to test this issue using EDGE.
The odd thing is my brother has the same phone and although he reported a few missed calls via wifi calling, nothing as serious as my issue of several blocks of time with 0 signal at all.
I noticed the new update rolling out changes the baseband.. would this do anything to fix any issues with connectivity? Ive read numerous people with this issue using various phones/carriers and the only fix seemed to be getting a new phone number. I hope this isn't the case.
I think you might need a microcell
I'm not sure if that would really help. Like I said I have above average coverage at my house. I never had a problem with my vibrant and the other 2 lines dont have problems. This morning I flashed jedi x7 and I now have a 3g and a H+ icon. I notice that im 95% on 3g and it sporadically switches to H+ randomly for only a few seconds. Also as about 6 hours have past, my network signal in battery usage is a solid bar with no signal loss. Time will tell if that stays true.
One other thing of note, if I perform a speed test when it's on 3g.. I ping 1k+ but pull around 15mbit. When H+ is up before I start the test I ping under 100 and pull 15mbit. Perhaps the constant switching is causing me to disconnect from the tower for brief moments.
