Signal and Data Issues - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Today my note randomly dropped signal, Then it wouldnt pick up a data connection even when it did have signal. Now it randomly jumps to 5 bars before going back to none :/ I Reflashed my rom and it made no difference. Have tried multiple modems, and even restored a backup from before any issues occured. Nothing seems to be working and i have no idea why! It couldnt be anything to do with the efs could it? I mean i haven't touched it at all and i do have backups.
Any help is much appreciated!

it's a shame no one has any ideas on this. Mine has just started doing the same thing. First noticed a week ago when my Dad was unable to call me. It's starting to annoy me a little!

I had i problem before, suddenly the downloading is so slow, i though my sim is the culprit. I tried to clean install and reflash, still the problem persist. The last thing did i format my internal sd and the problem is solved. I hope this help.

Hi Bud,
How's it been? How's the android development going on so far?
First of all, I would still commend you on your app (carbon tweaks) that have work wonders on my phone till now. Your app is simply awesome in making my phone simply 'sings'! . I truly appreciate your great efforts making that app carb. Such an amazing app indeed.
Anyway, going back on your issue. Have you tried changing ROMS already? Stock /ICS ROMS? is the issue still there amidst flashing different ROMS already?
Now if you say YES, How bout your network carrier or provider? have you called them up also? If not, you can try calling them.
The reason for that is, I too have the same issue as you have now. I was pissed off to the max on why I can't get full signal on my phone. Network connectivity would halt to a grinding slow up to the point of no connection and no signal at all.. then the signal would come back and it would disappear again. I tried everything as well, rebooted, flash ROMS, kernels, modems, wipe, but the issue woudn't go away still.
On the last effort I did, I called my carrier here in Portsmouth (AT&T) and I asked the operator if they have some upgrades going on on my location. And what comes to me as a surprise was that the at&t operator said YES they do have a network upgrade/s in my location and told me to just be patient and bear with them. I was about to blast them with all my frustrations but the girl operator was meekly apologetic and offered me some data packages added to my plan(that I simply can't refuse to deny).
Anyway, after that call, I waited till they've finally did an uptime on their end and in no time at all my my signal was back full bars and going strong on my phone.
Moral to the story is that... sometimes we are too pre occupied looking for answers INSIDE our phone that we fail to notice the OUTSIDE factors (that still counts) that makes our phone work also.
Cheers carb! :highfive:

Thanks for the comments about my app man I have to admit updates have been a little space lately but im young and not going to neglect my social life I really do owe you for the support though man! I will be sure to update you on any future projects I have
Turned out my issue was that my operator (o2) went down for most the country that day so that caused my issues and I just didn't realise xd

See? I told you it was just your carrier messing up with your connection.
I advised you on that and you called them up. It greatly saved much efforts on your time delving and sulking on the issue on your phone when the fact of the matter is.. it was not your phone at all having the issue... It was actually your carrier.
Next time bud, if your getting some weird connection problems.. my advice is, don't tinker directly down on your phone. Check your network/carrier first and see if they have some upgrades being implemented on your area.
Cheers bud!

[Q] Cognition, suddenly unable to send and revieve texts, internet not working well

Hi guys, I started having issues with my SMS this morning. Now, I can't send messages reliably, I'm not sure if I'm receiving them properly now either. On top of that, I am was having issues with 3g, sometimes the icon would not appear at all, and others it would not load web pages or send data via internet enabled apps, i.e. facebook. I must stress that I did not change absolutely anything, and that it just started happening. could this be a flaw with cognition? or is it just AT&T being... well... AT&T?
I assume it's just AT&T being AT&T, I had issues with that exact scenario about a month ago. Cog is working fine for me, but you can always try to backup and re-flash and see if that helps.

If it persists I will re-flash... pain, but what ever. Any-who I'm about to get an inspire 4g anyways so meh.
Thanks for reassuring me that I'm not the only one who has encountered this problem. I tend to have one-in-6-billion luck like that.
Please post in the Cog sticky instead of creating new threads.
oh and for the record I'm running 3.04. Looking in to 4.1 anyways, wondering if I can update it without having to wipe everything. Can I restore apps + Data if I go from 3.04 to 4.1, or will that cause all sorts of hairy issues still?
No problem at all. Did you do your research around the forums and see all the reviews about the inspire not being all that it's cracked up to be? Not trying to sway your decision or anything, just making sure you know what you'll be getting into.

I don't think I wiped anything when I updated, but when I restored system apps with TiBu, I got some FC's when it came to a few of the system apps and data, don't recall which ones though.

Wireless and network signals recently very low

Hi all,
Within the past week or so, I've noticed a fairly large drop in the signal strength from both my wireless lan and 3g signals. With the cell signal, it was even dropping to edge sometimes when I was outside in an area which used to give me full bars. Wireless isn't much better, and it seems to be fluctuating between 4/5 signal and 2/5 signal even though I'm close to my router. Again, I used to have full signal in the same location. Nothing really would have changed.
Yesterday I tried flashing Continuum (2.3.4) instead of running the stock 2.2 that I had before. The 3g signal seems to be *slightly* more consistent, although I'm still not at full bars, whereas I always was before.
Is this a common occurrence? Is it my hardware, and can I fix it myself, or do I need to send it in to Rogers? I've only had the phone for about 6 months now. I wonder if it's under warranty still (assuming I flash back the original ROM and bootloader).
If anyone has any suggestions it would be much appreciated. It's odd, but the wifi signal almost gets boosted when I'm trying to use the internet, but not to full bars even when I'm near the router.
Bump. Is this the wrong place to ask this question?
Cheers
My AT&T Captivate has similar issues. Mine started about a month ago. I haven't put any effort into figuring out the root cause.
Yeah, I'd really like to figure out what's up though. Does the hardware just crap out after a few months of use? Thanks samsung!

This trend happened with my HTC Aria as well. I don't believe its anything related to Samsung hardware crapping out.
So, if it's software, what would be consistent across a ROM and kernel flash?
I recently fixed a network error effecting call quality by flashing a new modem. I know our issues are different, but since you did flash new ROM i dont think it could hurt.

Have you tried flashing a different modem? The one that came with your current rom may be different than you had before which would account for your weaker signals. Different modems work better in different areas. Try something else and see if it doesn't help, such as JK4 or JL3.
I haven't yet, but I actually had the problem before I flashed the ROM.
Where are you located. I have absolutely ATROCIOUS reception in Atlanta, and ATT says they have some 50 towers down. Your area might be the same. In my basement where I used to have 3 bars consistently, i know have to run around the basement struggling to get one bar to send a text. ATT needs to get their act together or everyone might start switching to Verizon.
In Toronto, Canada. We usually have good reception. It's only recently that I have had issues.
check with other people such as your family and see if they have bad service too, if so call your service provider, there may be an issue on their end. Other than that all I can suggest would be a full reset to factory and a master clear and then restart from there. While that is annoying, it might be worth it to solve the problem.

[Q] When I turn wifi off, Note does not connect to 3G or HSDPA

Hi guys,
I have this strange problem, it even seems random.
After I turn wifi off, my Note does not connect to 3g anymore.
And I have to reboot the phone to get it working again.
Does anyone experience the same problem, or knows a sollution?
I rooted KK1 and flashed LA4 using Mobile Odin.
Cheers,
Daan
I've had this problem once, but it worked again after a reboot. Haven't experienced it again. It happened on KK5, but i flashed LA4 yesterday, so it's too early to tell if it will happen again.
It also happened on my Desire HD with MIUI and also while running CM7, so it might turn out to be a bug in Android.
I guess you had turned/switched off data network mode by pressing and holding the turn off button for two seconds.
Try and turn it off and see if it is the same symptom that you had before.

No, this is not the issue.
I manually set the APN settings for Telfort, removing MMS and setting it up for "internet" only.
Did a wifi on/off cycle, with a short interval and it seems to work.
Going to test with a longer interval. Not completely convinced yet.
Hope it's fixed.
---------------
edit: Not fixed!
On wifi for half an hour, turned it off and [email protected]#$% 3g does not connect anymore.
Maybe it's just Telfort. They don't have the Note listed on their website, but still.
My infuse 4g does this. I have to put it in airplane mode then back to get my data to reconnect. It did this stock and on serindipity 7. I couldn't find a fix either.

Annoying stuff! Cycling airplane mode does not work for me, only a full reboot.
But if you had the problem too, It could be that it's the network's (in my case Telfort's) problem.
Maybe I have to get my sim replaced, but I'm switching to T-Mobile in about a month.
So it's a bit of a pain.
I am currently using the infuse on o2 in Germany, but it did it on att in the states also. I can't wait to get my note. I am just waiting for it to be released on o2 over here. They have the black but I really want a white one.

Telfort used to be O2, it has been using KPN's network for a while now.
So it's probably not connected. Though it is a strange coincidence.
I'm off today, I think I'll walk by the Telfort store to ask for a new sim or something.
Maybe they'll have to flip a switch somewhere.

Yeah you're right, I have to troubleshoot properly. But it's such a pain
And I think I recall having this problem a few roms back as well.
I'm not sure because I was on wifi all the time.
But I have to wipe, I'll use titanium backup so it won't be such a hard blow
Man I'm going to pissed if it turns out to be the network

Thats a pain i was so tired of formating,..reformatting....coz many custom firmware have some error and new updates keep coming almost daily...and all ask to wipe for best experience..dat was when i finally decided to come bk to stock and stick to it...
yeah it doesnt hav those fancy colors and throbbing speed which a custom rom boosts about but...but hey everythin works flawlessly and i dnt have any tension of random reboots and alarm not ringing..or any smartphone related error to comeup...plus all my apps and schedule is there forever no reinstalling tension....enjoying my phone....
Okay, so I I did a full wipe and installed a deodexed rooted LA4.
I still have this issue.
Also tested on KK1 stock and still experienced this issue.
If it does this on KK1 and LA4 it's reason enough for me to believe it's the network.
I'll just wait for my T-Mobile plan to start. Meh.
edit: It seems to work just fine on CM9 :-/

Odd signal issues Atrix HD

I recently flashed the (Unofficial) PAC Man ROM over night, and noticed my signal bars were blank. I have 4G (It says sometimes) but when I check my signal strength, it's 0 dBm 99 asu. It can see my Network, says I'm in service, and gives me my IMEI number. However, my phone number is unknown. I'll upload screenshots, and will answer questions (Obviously) if need be. (Note: I can't post in the dev forms, as I don't have enough posts, thought I have PM'd Skeevy about the bug. ROM runs fine otherwise ) Thanks in advance.
Well it's noted as a known bug in almost all 4.2 roms so...

Hm. Read the PACMAN rom bug list and it didn't show up and that's what I'm using.. Oh well. 3G works, I get signal, but my phone number doesn't show up, so eh. I can live with it I guess,
I am one of those folks that will keep flashing for latest stuff cause I like the bleeding edge...
I did have a problem today that all my roms I flashed to had no service. No matter what I did... No bars and WIFI couldn't even be turned on.
End result fix was to flash back to ATT stock US rom through RSD. Then putting CWM back through fastboot and then my customs worked fine. I'm sure it was something dumb I did that caused it, but with an unlocked bootloader, I have no fear of trying anything

Honestly, I think it has something to do with the way 4G LTE is encoded with the ROM. I've flashed stock, gone back and installed CWM and re-flashed PAC and still had the issue. But It still works, I just don't get signal bars, with 0bdm and 99ASU all the time so yeah. 3G and HSPA+ work flawlessly. If I have HSPA+ and 3G I'm fine lol.
Now that GPS is pretty much figured out, which is what I've been focused on, I'll start looking at the stock build.prop and and compare it to PAC's. Should give me some insight to the 4g issues.
I wasn't aware that all 4.2 roms had the signal issue. I see it on PAC maybe once a day and its gone within 5 minutes. I'm not 100% positive, but I think it has to do with wifi. When ever I notice a wifi issue like it not connecting as fast as it should, sure enough the grey icons follow.
Went to Taco Bell last night, saw their wifi connection but didn't connect. Got home, home wifi was slow to connect and they grays. Makes me wonder if there's an issue with the wifi queue or the phones "which internet do I use?" queue.

Last line made me LOL.
The issue just seems to be 4G and LTE. WiFI on your PAC rom seems runs wifi great, but sometimes it disconnects (very rare for me, but I think it's for everyone in my house, we have quite a few WiFi hogs, lol). I'll just keep flashing your new roms as they come out, and hopefully it'll be fixed. Not to big of a deal if it isn't lol.

Did you compare signal rating from your stock ROM to custom ROM?

If you have an older router, try changing the WiFi frequency from auto to 2.4ghz -- fixed my WiFi disconnect issues right up. Also, if that doesn't, then set up a static IP for your phone since, in my experience, static connects a lot faster. That's not really a bug as it is a hardware issue (an I can't afford a new router issue).
As for signal. Can't test LTE\4G. Not available in my town. 3G works fine and doesn't have any disconnect or signal issues. I can suggest to try different modems from the various fastboots.
Its just that the custom Roms don't "see" the 4g signal is all... So it gives a no signal bar. Its different from the connected bars and fully connected bars that still show signals.

Losing mobile signal frequently

I have an issue where I lose mobile signal every few minutes. If I use Llama and check the "recent" tab I can see Cell: -1:-1:-1 every 10 mins or so and if I'm using the phone the signal will go to nothing, then within a few seconds go back up. Has anybody else seen this issue? I've done a factory reset and it didn't help. I'm waiting to hear back from Sony support, but they're been pretty useless for me in the past.

I encountered the same problem on my xperia l.
You could try taking the battery out the phone when it is switched on "hard reset" ,then take out the sim card and reboot, then switch off, put sim card back in and reboot, it may take a couple of minutes, it's worked for some, Me included
Another thing You could try is putting Your phone into GSM mode from settings but this means You need to keep changing modes when data roaming

Whilst we appreciate the sentiment please take a look at the forum your posting your advice in. The Xperia Z1 does not have a removable battery and the term 'switched on ''hard reset'' ' makes no sense unless you mean using the red button in place of a battery pull.
Not trying to be rude but its frustrating when your device drops signal and the best advice you get is regarding completely different hardware.
To Chrisduffer: Have you rooted your device/unlocked the bootloader or flashed another ROM? If so perhaps consider an alternative Kernel or a software update via the flashtool if its still using the stock kernel?
same problem. No root / no flash. Stock 4.3. Same issue even before update to 4.3.
Any idea what to do? My signal drops down every day like 5-6 times for about 20-30 seconds with no reason. I'm also not able to connect to 3G (at least phone is not showing 3g sign next to the signal strenght).
Hmm...this is interesting because actually I saw this up and down on mine too but I was able to call and receive calls anyway...so I newer bother if is an issue or not...but I losing the internet connection frequently so what's wrong?
Instresting...mine too...stock 4.2.2 rooted, Lb....but when my signal totally drops I am able to call or text!

Sounds almost like the modem driver is crashing and then restarting. Factory default is what I would try first, unless this is happening in places where you have weak signal or are in an enviroment which would cause weak signal (inside, thick walls, metal, etc.).

Hypothetically.
Had a few issues myself with the same stuff. Try another radio via flash tool. Just deselect everything else and just flash baseband, no wipe. Be careful when flashing stuff.

Yes, alternative radio driver should help, if it's not HW issue.
I will try to give the phone on a warranty check ... hopefully they will be able to tell me what's wrong ..
if not, I'll go your way = flashing different ROM with different radio.

thank you for the answer which rom could i install? now i have the rom for italy (IT) that i found here... but i had this problem also with the completely stock device so could it probably be an hardware issue?
You think you have signal issues?
Almost forgot, I had a phone come in once and it had the same issue, ended up only recognising the sim card every now and again, you could try another sim, or even send it back for repair which is what happened with the phone that was brought to me.

so i'm going to send it to warranty, i hope it is an hardware problem otherwise i'll have to sell it, i can't stay witheout signal as soon as i hold it on my hand
losing data signal
I am having the same issue
Any idea?
Should return the phone?
I sent the phone to the warranty, I have also the results of the tests and they are all passed... So I really don't know how to do... If I find a nexus 5 i'll try to change this xperia for that, I can't stay whiteout signal when my old iPhone 4s receive it very well
