Yea I noticed it today... it is kinda weak

No I haven't noticed this. Although there are Los signals that get lost a lot. Try chirs's kernel to solve this.

It shows only one bar on mine but i get full speed(20mbps) from time warner when i do speetest where as evo 3d only shows 8mbps . THat single bars mean nothing check your speed with speedtest.

Signal and wifi speed are fine just the wifi reception is weak for some reason. Im about 1-2feet away from my router right now and im getting only 2bars.

wifi reception on this phone isn't great

My wifi is great it works really good. It might be your router.

Mine always shows very few bars but I can walk out and get in my car and drive around my condo building before Signal Alert beeps that its disconnected from wifi. Looks worse than it is.

I used to use WiFi on my patio and in the garage to stream music with no problems on other phones. With this one it disconnected as soon as I went out the door. Finally did a factory reset as recommended on another forum and it helped a lot. I can use it outside now. Still only one bar, but it works without disconnecting.

WI-FI Issues maybe?

Hi there, I just pick my Note 2 yesterday and coming from the EVO LTE there are some PROS and also some CONS
but first... my dang WIFI keeps on turning on by itself... I have to be turning it off at least every 20 minutes i don't want it to kill my battery...
anybody else having this issue?
PROS
Bigger screen, not necessarily better
Way faster Multi tasking is great
Camera is really fast
I CAN DRAW =)
I can set a 5x5 Rosie and still look with plenty space
LOOOVE the stock keyboard... i can swipe in 2 languages with out having to switch and also access numbers without having to switch to SYM
CONS
no data and voice at the same time (really miss this feature)
poor signal
less handeable (until you get use to it)
Not otterbox support yet =(
I dont know... Overall im happy with it, but i have been a HTC fanboy for 6 years... this is just different... but its a process...

Hi.
No , i don't have this problem.

elculito, can you go into more detail?
What signal? GPS, 3g, LTE?
Many thanks.

I had my wi fi just turn on by itself a lot too. I'm in an area at work where i have a low signal and my 3G goes in and out.. I also have a wifi hotspot on so maybe that's why. It would turn on the WiFi when my 3G would disappear.
Thanks for the tip!

On a related note I am pleased with the Wifi strength on this device. Far superior to the gnex. Also, signal strength seems okay on the cellular side. My office is a borderline no service area, if a phone is truly bad it will drop calls. No dropped calls yet for me with the note.

4G=> Hot Screen/Fast Battery drop/Other?

I"m on the ROM per my signature. My home is not in a 4G area.
Last night I was in a 4G area, and not sure if what I experienced is expected; or if not if it has to do whith my ROM>
First off, I lost data connection and had to reboot in order to re-establish connection to data, a couple times. I also found that my screen more so than the back (with a think battery) got quite hot. I also noticed the battery dropping quick.
I suspect a possiblity of poor signal where I was at. Did not make any calls. Now that I think about it, the signal bars was not a full 4 bars.
Just wondering what others think.

I also would like to say I'm experiencing the same issue. My battery is much better now only because I turned off LTE. Just a temporary solution. I'm gonna follow this thread to see if anyone can help.

Well, I was up in a different area last night that had 4G, and I had 3 bars. The phone battery did OK, and I didn't have such a hot screen. But it was New Years Eve dance, and I didn't take time to try to communicate over Internet.
But it leaves me feeling that my issue was that the 4G was not good coverage where I was at before, May be a while before I"m in the same area. But I'll keep updating as I experience different 4G connections.

Note 2 showing no data connection?

So I just switched from an iPhone 5 to a Note 2 and I love it. But for some reason when I go to look at my battery stats it's showing I don't have a connection for most of the time, even though I have a connection, can see the full status bar up top and can use my phone perfectly fine. Has anyone seen anything like this? I got a new SIM card from AT&T before I switched phones so it should be working fine. Also with all things considered, is this solid battery life? Thanks in advance for any help!

Is this your first android phone? If it is then I understand why you don't think you have a data connection. When you're on wifi, unlike the iPhone, the android phone will not show the data icon unless it is using the data network to set your location or something like that. It will only show you your wifi signal strength icon. If you disable wifi you'll notice that the data icon, 3g,4g,4g LTE, will show up indicating you are connected.
As far as battery life, it seems that you use the internet quite a lot considering Google Chrome is using a large portion of your battery. If that is true, then over 11 hours is pretty darn good I would say. The screen is always going to use most of your battery throughout the day, so it's best to lower the brightness when you don't need it to be bright and shut it off all together when you're not using it. This will save a large portion of your battery.
Anyway, hope this helps a little.

Thanks for the response. I had the EVO and EVO 3D so I am familiar with the fact that it shows the Wi-Fi connection up top. I was more concerned with the picture where it shows how long it's been awake, screen on time, Wi-Fi on, and mobile data. Under the mobile data it usually shows green for strong strength, yellow for weaker, etc. Under mine it shows very large gaps of black, which I can only assume means no connection? It doesn't seem to correspond with when I have Wi-Fi on, as there are some parts where Wi-Fi is off and the mobile data shows black. I hope this explains the problem a little further. Thanks again for any help you can give!

Ok, I understand what you're saying now. Black seems to indicate that the radio is turned off. Other than airplane mode or turning the radio off all together, you shouldn't be getting black bars. I think they should be red if you have no signal, so yeah, that's weird. Is you're phone rooted? If so, what rom are you on?

No, the phone is not rooted.

Well, there goes that idea. That seems to be the latest version so honestly, that's as far as I can really help you. I was hoping you were on an older version of the modem and an update might fix the problem. All can say is, if there are any updates available, run them, if not, wait for someone with a little more experience to help.
Sorry,

Op have you tried a factory reset?
Try this first.
Also n2 has the best battery life of any phone I have used. I get almost two days out of it on moderate use amd a little over 24 heavy usage.

Bump

Not sure if it is really anything to be concerned about. I have a significant gap in what it is shown as network signal strength as shown in first photo. Does not show any in the GSAM battery report in the second for the same period of time.

[Q]4G data speed very slow during call

Hi, I have a galaxy S3 with T-mobile. I'm in a place where I have excellent 4G speeds (about 5-6 Mbps :speedtest), I noticed that when I'm on a call the 4G data speed drops to useless speeds. I can barely open a website or download an app. Speedtest shows like 500+ ping and about 500kbps download which is NOT constant (goes up, stops, goes down, etc). Real speed is way less than that. Websites don't open or take forever.. Is this normal? I am using stock rom (but also happened with other roms). I went back to stock thinking that this was a problem with other roms only, but the same thing happen with stock rom. Any ideas/clues/solutions? thanks in advance

Long ping times is normal due to how it operates. But only 5-6mbps? That's pretty slow. Most get averages of 13-18mbps and some get averages around 25.
Try the different modems to see which will be better for your location.

So, its kind of normal to get slower speed while on a call?

It would seem a logical conclusion. But I've never tested it. But I've never had anything not load or go slow enough for me to notice. If I think about it on my next call ill try to test it out.

Ok thanks, The problem here is that I find it way to slow.. lets say I'm downloading a file with no phone call going and I get 600KB/s, during I call I get like 16 to 40KB/s at most... It's like having dial up again... way to slow.. I think something is not right but can't figure out what, since I reverted back to stock wiped everything and also formatted the system after installing stock..

Have you checked your imei or ever lost it?
If not you should really try the different modems.
If this is a recent development you should also call support to see if they have any tower issues in your area.

IMEI still intact, and have never lost it. I will try with different modems thank you! I'm not sure if this is a new issue since I didn't use my internet as I am using it now while on a call before, also I moved from Puerto Rico to the states for a few months, so there are many variables at the same time. But will try with the modems.
Another question, when I odin Stock (not rooted) ROM does everything (incl. modem, kernel, etc) goes back to stock?

Hello, spent the whole day testing out every single JB modem from your post and none of them solved my problem... did find better speeds with some on them while not on a call. But as soon as I'm on a call the speed drops to about 47kbps, looks like a cap or something because I get constant speed of 47-49 kbps. Sometimes it goes over the cap and works normally but for a few seconds then the speed drops and its not constant anymore until it reaches around 47kbps... This is so frustrating... is there anything else that I can try out??

Flash the LJC firmware package. Third firmware link in my signature. This is for SGH-T999 (d2tmo) only. Unsure about the download cap while talking on the phone. Aren't the two separate? Cell and data, right? Shouldn't be a cap then, but I've never been talking on the phone while downloading a file. I will try it if I think about it tomorrow.
5-6Mbps is not bad. It just depends so much on where you are. My fastest test ever was the other day @ 14.4Mbps. It's not a big city, but it's sizable. It's usually under 10Mbps in that location. And normally less than that everywhere else in the area. There are some areas that put me on Edge. Might as well just turn on airplane mode. Because T-Mobile's Edge... is actually worse than no data connection at all.

Thank you, will try that tomorrow. 5-6mbps is fine for me but that is without call. While on call is like 0.37mbps constant or really bad ups and downs.. is like edge (worst than not having connection at all).. anyways will try and report back. Thanks again

Sorry I couldn't remember this before, but I have a theory that could explain what's going on there.
Voice calls and 2g (GPRS) both share the same frequency spectrum. I remember doing some 3g research in the past and one of the benefits to the introduction of 3g was more overall bandwidth for all, even those left on 2g. At the time, 2g data service was greatly impacted by how much voice traffic was going across the network at any given time.
During peak voice call times, there was less bandwidth for mobile data users because the tech was designed to give priority to the calls. This meant even slower than usual 2g data speeds.
But as people moved to 3g, there were less using 2g for data lessening the impact caused by voice and sms communications.
So what I'm getting at is when you are on a call, that call is going across 2g frequencies, meaning you are connected to 2g. (Though 4g data should still be available to you regardless. But it may have something to do with what you're experiencing.)
Keep in mind that this was 3 or 4 years ago. I'd think that it'd work differently now. But it is possible that they never changed the fact that voice shares its spectrum with 2g. I could be seriously off with all of this, but I still thought I'd mention it since it would make a little sense with the speeds you're seeing.
The thing is, the S3.is capable of using DC-HSPA (dual carrier) which means it can use 2 different signals at once (one from T-Mobile, one from a partner carrier) for greater speeds (HSPA+42). So I don't understand why it won't use this same tech to give you better data speeds while on a call.
I know I've used mobile data while on the phone before, and never felt like the qos was lacking. But I never speed tested it either.
The more I think about it though, the more I'm thinking it's either firmware (see aerowinders post above), hardware, or you're connecting to a tower that either has problems or hasn't been upgraded in a long time. I don't believe that what you're seeing is normal operation.
Of course every bit of this is speculation at this point. Hope no one thinks I wasted their time with it. I thought it may spark some ideas though!

Hello, I still have not called customer service, but I'm going to be back where I din't have any problems next week. I'm going to test it out there. If I don't have problems there, then it's this area the one with problems. Anyways I will let you all know my findings.. Thank you all for the support!
Edit: I just confirmed that it works perfectly fine where it used to worked fine. It must be the new area where I moved recently that has issues. Thank you all for your time and help.
