Hi Guys!
I'm using a stock AT&T Galaxy note, Yesterday when I went to the hospital to visit a friend, I've lost the 4g signal, however It does show gray 3 bars without any abbreviation beside it so I would assume it's on EDGE.
I've tried calling or sending text messages at that point, but then all my calls wouldn't connect, my messages all failed.
Luckily I'm with my sister at that time, she uses a blackberry torch. Same signal as I had and she didn't have those kind of problems.
Did this happen to anyone else? I'l still try to test EDGE connections if I happen to stumble across one in the future. Right now, I'm a bit confused, a little bit scared because when I travel, I get edge connections and if the phone does not work with EDGE then it's something that I have to seriously think about replacing this device.
If it has no abbreviation beside the bars, there is no data connection. Edge will have an 'E' beside it. As for the texts and calls not going through, you probably were in a dead spot.
I sometimes hit edge areas and it shows an 'E' with slow data but data nonetheless.

Thanks cmjkxa, I didn't know that
Just weird, coz the torch running on the same network functions normally.
Edit: when connected to wifi, it doesn't show the icon what kind of connection you have, "4g/lte/g/e"

I've been having this problem for about 2 weeks now. First I was using Radio 1.50 on the AT&T network in South Jersey and out of the blue when the connection would go from 3g to edge I could no longer connect to the internet, receive emails or anything, voice was fine. When I would get back into 3g range everything would work again. So I upgraded to radio 1.54.07 and at first everything was fine no problems what so ever. But after 5 days this radio does the same thing, I cannot do browse the web or get my email if i go from 3g to edge but everything works fine once it is in 3g range. Anybody have similar problems or know how to fix them?
Just to clarify things, when it switches from 3G to Edge my phone still shows that there is a data connection but for example if i try and look up something in Opera it says looking up host and then times out. Any program trying to use the data connection times out, which is weird since I never had any problems til about a month ago. I've tried soft reseting and still all it will find and connect to the gprs signal but all my connections time out if i try to look anything up
I have the same misterious problem. Did anybody - especially jc67 - already found a solution for that?
Hi I ran a search and did not see anything that looked like this so..
Usually on my phone I have a reception of 2 bars 3g. when i send an sms message my signal drops to 2 bars 1x. After the sms is sent it goes right back to 2 bars 3g.
Don't know if it is just a display glitch or if it is actually dropping 3g.
Does not happen when using browser.
Sometimes does it when receiving sms.
Anyone else have this peculiar behavior with their phone?
This is how Verizon's network works you are not seeing anything out of the ordinary. It is also why Verizon customers can't surf the web and talk at the same time like AT&T guys.
Ok. Thanks for the info.
Ever since I've transferred to AT&T I've had laggy data issues. I finally rooted/flashed to AOKP, and while trying to address the issues of no APNs appearing or saving and no signal status in the status bar, I've come to find both AT&T and T-Mobile as Available Networks under some network setting. Am I chasing ghosts here, or is there something actually up?
EDIT: So I really need help troubleshooting the issue. I'll logcat, dump, or whatever necessary. I've been in many cities/areas and this problem persists: if I haven't used data or the phone hasn't been backgrounding traffic, it'll take anywhere from 5 to 30 seconds before a connection is made when I try to access an internet-related function on my phone (even though 3G/H is displayed in the status bar). Out of shear frustration (this has been happening since I got the phone, under stock ROMs and now under AOKP), I tried messing with *#*#info#*#*. I changed WCDMA-preferred to WCDMA-only -- no improvement. Oddly, I also tried GSM-only. Well, great improvement! Even though I only have E, there is absolutely no latency in waiting for a connection -- so pages and other data end up loading faster on Edge than 3G !
I have absolutely no idea why my phone takes forever to make a connection. Under 3G, I see only but a few upstream network activity blips (even under full bars) for as much as 30 seconds, before there is any downstream activity (and when it comes, it comes). Can anyone help???
P.S.: I'm going to try using a friend's SIM later for comparison.

Because they both share the 1900MHz band I believe.

On AOKP it does for me too. Just ignore it.

An aside: does your phone stay on 3G and switch to H only under moderate network traffic?

The phone displays 3G because thats what it is... then when data is being processed, it shows H because its using the "what AT&T calls 4G but its really HSPA" side of the network. For just standby time with no data, its going to show 3G because HSDPA is traffic, not standby.

Well that's strange. I'm used to phones displaying what network-level they are capable of. So why would it not just display H for HSPA+ when HSPA+ service is available, instead of only displaying under traffic.
I'm going to go ahead an edit this thread to help troubleshoot what I think to be the main issue.
After some trials I see that the network indicator switches back and forth between 3G and H a few tines before making the connection and transmitting data. Hmmm...
Basically, "4G" will eat your battery alive so the phone idles at 3G and jumps to H+ only when you use data. If you were on a "stock" ATT rom it would always read H+, but this is technically false since when its idle the phone sits in 3G. CM9 and AOKP accurately display it which is why you see the switch.

I have a HTC Amaze for a phone and the Galaxy S2 is my media player. Sometimes, when I don't feel like carrying around two devices, I put my T-Mobile SIM in the galaxy and use it as my phone. I must say, Edge is not as slow as I remember it being. Maybe speed is contingent on network traffic. If thats the case, instead of using crowded "faux G" networks, I may defer to Edge to save battery life and get good dl/ul rates.
My phone does the same thing. I noticed it sometime ago. When idle 3g. Internet I get H+. This is with both Shostock2 and Phone Bricker. I was curious to know too but just blew it off because it really doesnt make any difference to me as long as Im getting decent speeds. Im not even with ATT anymore. Went with Straight Talk. Which uses ATT towers. Cant beat the price!!
They don't have the correct apns, but that symbol problem is because the phone doesn't use hspa+ passively, only actively. It causes some lag when downloading, but it is faster fit large data. But your problem is due to a supposed imei range with bad modems. Rehash stick, fix the triangle, and return it.

Hi All,
I am having a strange problem with my S2 since last few months. I am from Mumbai, India and using Airtel network. There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while. It happens that whenever I take my cell in that area, it starts losing signal bars till no bars are highlighted on the status bar at the top. It keeps showing zero bars but does not show "no signal" icon. Then, after keeping my cell in that spot for a while when I bring it in a better connectivity spot, signal bars start increasing and it appears that my cell has better reception again. However, if anyone tries to call me or I try to call anyone, they get "Out of coverage area" message or I get "Network registration failed" message respectively. I am having this problem since the day I started using Airtel and have tried a lot of remedies but only thing that works is rebooting my cell. I have tried using OpenSignal app to reset my connection whenever my cell comes back from the spot but even that fails to revive it and ultimately I have to reboot.
Has anyone faced such an issue and any ideas about a fix? Does it look like an issue with my cell or could it be an issue with my network provider? I would prefer not to root my S2 since I have 3 years warranty on it but if you think that it's the only way out of this, please let me know your opinion.
Thanks.
Sounds like a carrier issue to me. You pretty much said exactly that yourself when you said 'There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while'.
That's normal in many buildings. Particularly if the network coverage in your area is borderline or poor. I have a similar issue in my house, in a few rooms I get no bars & sometimes coverage drops out completely, whereas in my loungeroom/dining/kitchen at the back of the house I get good coverage (for me, anyways).
You could try different modems, which might improve things. You don't have to be rooted to flash these, you can flash them using Odin. Tho it is easier to flash them with CWM if you're rooted.
I use to had the same issue with my 3 carrier at my desk in the office, and still on 2g services. I but since last month they already improved to hsdpa network added more bts and now my blank spot became H.
Yes you may try to change other service providers

Thanks for your suggestions guys. Yes, it might be only related to the carrier. But, I think that if signal goes down to zero and then when my cell is back in better coverage zone, shouldn't the modem take care of network registration by itself? My problem is that it doesn't. I have to reboot my cell every time after I come to know that my cell is showing signal bars but is not actually registered on the network. If I reboot my cell, everything becomes normal and so if it was just an issue with the carrier, shouldn't it continue like that even after reboot? If I think about it logically, I think following should help me out:
1. Try out a different cell for a few days and see if I face this issue or not.
2. If answer to 1 is no, then try out different modems on my S2 and see if that helps.
Actually, I just wanted to check if anyone else has faced this issue and figured out that something is not right with S2 drivers or something? That would help me with quick resolution of my problem.

Yep, your logic is sound ;-)
One thing tho. With regard to trying your sim out in another phone, you have to keep in mind the radio hardware is obviously different in different phones. And what that means is (and this is something I've observed on XDA), chances are you'll find the sim works perfectly in the other phone & you have no issues at all. This might be due to the actual equipment your carrier is using in the cell tower(s) you're close to, also the frequencies that gear is using might also be playing a part in your problems.
So definitely try it out in another phone & see what happens, but you could do worse than try out a bunch of modems in the S2 & see if that improves things.

Those are carrier issues, and maybe even the material of the constructions, in my house there are rooms where there's almost no signal at all, and in the living room it's ok, you should try to see in which tower you are connected maybe thats the problem
I have also had these problems on various networks here in Australia. If you don't need the data network, you could try using 2G only option. But that's not really a fix, is it? I suggest you try a pre-paid SIM from another network provider, to test them out first, before re-contracting.
Good luck. :fingers-crossed:

Yes, I was also thinking about it. It could be the combo of cell tower and S2 that are not liking each other that well.. And, if that's the case, I really hope that the issue can be resolved by switching modem drivers. I will have to do some what-ifings to nail this down now.
I like the other suggestion by HotrodHarry on trying out 2G only option - not the best way out but will help me in zeroing down on the cause.
Is anyone else constantly losing 3g? I can be in an area 1000 feet from a tower and I still drop to 1x. It happens all over the place. Resetting data through ##3282# does not resolve the issue. The only thing that helps is going in and out of airplane mode

That seems like such a blanket answer to any signal issues. If it were just towers in the process of being upgraded, why would cycling airplane mode on and off fix it? Why would my girlfriend's iPhone still have 3g? I just wanted to see if this signal issue was at least not unheard of.

When you put phone in airplane mod, it disconnects from tower, then reconnects when you turn your mobile data on. Your girlfriend iphone doesn't have the mod to show 1x. Plus the last radios update was buggy. Hopefully sprint will rectify it soon.

Just to possibly clarify on what the OP stated, I think I'm having the same issue. It would be nice to know that this is just a tower thing for right now, not a problem with this highly anticipated amazing phone...which isnt so amazing right now.
BTW, I live in Largo, Florida, and I've noticed these 3g drop-outs all over the Tampa Bay area. The frequency of these dropouts is very strange though. Heres my issue with it, maybe this is also what the op is experiencing..
The phone is on, 3g works fine, texts go through, internet works, etc. All of a sudden for no reason, the 3g icon disappears. I still have 2-3 bars, but text messages and internet, etc., does not work. After weeks of this, I put the mobile data toggle on my homescreen as a widget, sometimes i can click that off and back on, and 3g comes back, sometimes it doesnt. Lately, its been more on the "doesnt" side. So then I'll be texting with someone, 6-10 text messages in, I get a "failed to send" or "could not send" message. I'll still have the 3g icon, but i notice the "data arrows" directly underneath it do not fluctuate. I understand its only a graphic, and may not be a true indicator of upload and download. anyways the only way to get messages sending again is to reboot the phone. And now lately, that too has been "sometimes working". This will even happen if i switch to wi-fi, the messages still wont go through.
Its very frusterating, seeing as how other sprint users I know are not experiencing this. (they dont have an Evo LTE)
