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.

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.

So Im sure any of you on Tmo UK will be aware of this new option they've given us whereby you can opt-in to use the orange networks if you lose reception from Tmobile........
I thought to myself "yeah...... why not..... cant hurt"
Seeing as I barely get a 3G / HSDPA signal where I live I thought that perhaps it might kick into "orange mode" and give me some 3G action.... (sadly it doesnt)...
Anyway since I opted in Ive noticed that sometimes when Im on the Tmo/Orange signal, the "Edge" (E) symbol is displayed in my taskbar......
Its definitely a lot faster than GPRS but doesnt seem to be as quick as HSDPA, I thought that perhaps it was there in place of the 3G symbol but sometimes that will appear too.....
I thought "Edge" was only available in the US.....
Does Orange have some kind of in between speed that I was previously unaware of??

lol you probably wont need it in London........
coverage is poor out here in the sticks though..........
it perhaps won't auto switch networks, because it knows t mo is the preferred network, unless there is no t mo reception at all.
you maybe need to add the orange network as a preferred network
settings menu all settings personal phone network tab set networks let's you set the preferred order and such, so if you find yourself in an orange dominant area move orange above tmo in the list.

OK I'm generally a proud Londoner (Not a bad thing lol).. But sometimes I've been in the middle of Oxford Street and notice I have no reception, London isn't a great place for good reception is some areas, you get better reception in residential areas then main high streets
@sam...
Mine seems to switch even when I have a reasonable amount of signal.
9 times out of 10 today when I looked at my phone I had the roaming and edge symbols sitting in my taskbar....
I generally never struggle for basic network coverage so I was surprised at how often I'm on orange signal...

Yeah I guess there are plenty of things that could hamper you're signal...

Battery Drain
I've also just signed up to this as I get poor signal thru T-Mobile when in some buildings whilst at work.
Problem is that I've noticed a significant drain in battery since subscribing presumably as the phone is always comparing signal strength of both Tmo and Orange and switching between the two periodically.
Is there a way to change carrier manually through some form of *#*# dial code rather than to switch to manual and select the desired network as this takes a while? I don't seem to have the option to set my preferred networks as a previous poster mentioned.
I've had mixed experience with this - make sure your sense and activesync settings are set to NOT download data when roaming - the Orange/T-mobile thing calls itself roaming and I kept getting password incorrect responses from gmail on activesync, I assume because it was trying to access the servers from different IP addresses rapidly. You do not get 3G etc from Orange - your data comes over t-mobile, you just roaming onto the Orange network when there is no signal on t-mobile, so it should give you better call coverage, but for data switch off roaming so it only tries to access data when on t-mobile.

Hey, I have an USA T-Mobile Vibrant.
It is rooted and running the Vibrant edition of Darky's 9.3 Final ROM.
I am also using the latest overstock kernal and the honeycomb 2.0 theme from the I9000 forums.
Enough background info. This isn't really a problem as much as my curiosity.
My phone almost constantly is switching back and forth between 3G (UMTS) and H (HSDPA) on my data connection.
It doesn't seem to affect battery life or service too much (though H might be faster), so I'm not worried; but does anyone know what the deal is with this?
Thanks ahead of time!!!
Sent from my Vibrant using XDA App
Mine has been doing this lately as well. It's only been happening since I installed my current ROM (Trigger 2.7).
Noticed this just now as well...might have something to do with the mods to show H or 3G.
I wonder if it has anything to do with signal strength. I know that shouldn't make a difference but I can't think of any other reason.

I would agree, but I went to my settings/ phone info/ signal page and the reason it was changing was because it was physically switching between UMTS and HSDPA.
Why? I have no idea.
I do live in a T-Mobile 4G enabled area, though I am not on their so called "4G plan".
I did notice that it did not have this switching problem on Bionix Frost-u2.
So, if anyone has some insight, please help us all understand

I was just watching my signal strength change and it doesn't seemed tied to the change from 3G to H.
For example, it would be around 67dBm and be on UMTS. Raise to up to around 75dBm and be on UMTS. Then it would switch to HSDPA and still be at 75dBm or sometimes lower down to 69-72dBm and still be on HSDPA.
So with that type of cross-over stats, I would be skeptical of that solution.
HSDPA is a temporary data link. If it was on continously the phone would have very poor battery life.
When network server has a data packet for your phone it 'pages' up your HSDPA capability. Your phone can also request HSPA to initiate a data transmission.
The HSPA paging process is similar to receiving and initiating a voice call.
If no more packets have qued at their server or received from your phone after some period of time it will revert to normal 3G battery saver cycling. It has to be re-paged up to reinitiate HSPA data link. The wake up HSPA function does add some initial delay.
So is there a way to force it to stay on HSPA while tethered, for example? (Or always)
I've been having this problem probably once a day since I've gotten the phone where my phone will lose data signal while switching between 3G and LTE and the only way to get data back is to restart the phone. Turning airplane mode on and off won't work either.
Ive had that issue too..but most of the time it switches back n forth no problem

the 3G our phones use is not exactly the same as standard 3G unless you force your phone into EVDO 3G via the ##778 menu. which if you are not in a 4g zone I would recommend simply for stability. The 3G our phones use is basically a layer between 3G and LTE as I've had it explained to me.. I really don't know much else about it though, sorry. I'm sure someone else here can shine more light on it however.

I've only had this happen once with the rezound. Shows nothing but bars, no data can be used. Sometimes switching to 3g or 4g in lte on/off helps.
Had this problem intermittently on both my wife's and my bolts, completely agree its just a lte being a new tech issue.
I've listened to a podcast on how the handoff works and its definitely not fool proof.

This changes your network from eHRPD back to EVDO Rev.A. For LTE phone owners, eHRPD causes 3G to die (most of the time anyway) when the LTE network has problems. Get back on normal EVDO and you're good to go.
^ from Jntdroid on another forum (not sure if we're allowed to post to other forums here) I'm not positive on where he got it from, but this is a capability of all HTC 4G phones
I've had occasional issues with being down to 1X, but even that was only during nationwide 4G network issues, definitely get in touch with VZW about that... not that they have enough sense to fix anything *sigh*

Same issue as you. I live in a 3G area only and my 3G drops out a lot. Even a reboot doesn't get it back. Not sure what to do :/
Im so pissed off at this phone. Supposed to be fast but my browsing experience sucks because of this delay between 3g/h+
Before I get flaimed I have read before, I tried fast dormancy off, I tried disabling H+ and putting 3g only but the same delay exists. I also tried putting the phone in wcdma mode so edge gets removed.
I don't know what to do, I came from an iphone 4 and although the pages load slower because of hardware I could actually see the data progress going and loading up, here my sgs2 just stands for 10 seconds doing nothing and then loads up the page fairly quick.
Sometimes it doesn't even load and says page could not be loaded even though I have the h+ icon on.
Now If anyone experiences this and has some sort of fix plz let me know.
Im running westcrip 9.6 with lph, and have had this issue in previous roms too.
My network is Claro Dominican republic
Thanks
I have a similar problem! In my case the phone suddenly switches from H to 3G, I don't know why, and then goes back to H. This happens while I'm using browser, generally when I activate data connection and I don't use anything, it remains on 3G
My problem is that sometimes the delay may be 2 seconds and its managable but then it can go up to 15 or not do anything at all.
Same problem, I thought it's ok, but if it's not, then how to manage your data, without any delays?
just in case for someone who might know how to fix your problem u should give them/us information about:
your rom
your kernel
your modem

carrier and location (country) would be good too.
EDIT: whoops, saw it's in the first post. Sorry.
Its normal to go from G to H+ when data is in use. As soon as the phone detects that it needs to access the network, it will achieve the H+ connection. Apparently it will kill the battery if its always on H+. This, I understand. But the part I do not understand is the delay from G to H+. I am not sure if its a carrier issue for most of us, or the phone itself. I am assuming its a carrier issue though as it has happened on every ROM or Modem I have tried from personal experience. Not sure about the OP. It does seem to take some time at times to get from G to H+ - upwards of 15 seconds or more. Also, if it can't get H+, it will not browse at all on 3G

I don't think so. Seems to be a device issue. I just took a look at my Blackberry Bold 9900 I use for work and it always has H+. It doesn't go to 3G and then to H+ like the SGS2 does. And when I browse on that, its always ready to go, no delay. Not sure why our SGS2 needs to handshake H+ everytime
In my case it seems to depend upon the modem I use. kL1 works really well, however when I trialed ICS it was really slow as described.
Also, far less related, as for the mention of browsing, I use Dolphin and find that it seems to be much slower at either DNS lookups or redirects or something.
It's most likely because of your carriers settings. There's nothing you can do unless you call them questions about what their policy is at their end on data connectivity.
Good day all!
I've been experiencing some issues since I got my C6806 3 weeks ago. I live in Toronto and my provider is Rogers. The phone itself is unlocked and is just running the stock software which is 4.2.2, build # 14.1.B.2.257
Ever since I got the phone I've had a periodic issue where the phone signal strength will just completely die out to 0 bars, then it'll come back to full bars about 30 seconds later. It happens whether I'm home or out on the road. It happens if I'm using LTE bands or 3G or HSPA. It also happens whether I've got wifi on or off.
Any troubleshooting steps you could suggest?
Thanks in advance!

How's LTE and HSPA where you are? If the signal is poor it'll switch over to the next thing on ladder. If you have a poor LTE signal it'll jump down to HSPA, and if you have a poor signal on that one it'll jump down to EDGE. It's the same dance if you walk into an area where there is good LTE coverage. It jump up from EDGE or HSPA to LTE, and iin all cases when it switches, you'll notice a couple of seconds where it connects to the new frequency (by having zero signal). That's why I disable LTE when I know I'm going to be in an area with poor LTE signal for a long period of time.
Not saying that this is your problem, but try only using EDGE for a couple of hours and see if it happens again.

LTE and HSPA coverage by Rogers in Toronto is great overall. I don't really use the LTE APN because it seems to suck up battery life immensely. I just keep it in the normal APN that seems to switch randomly between HSPA and 3G. The issue can occur if I'm just sitting still in a spot. I'm using it, and all of a sudden the signal just cuts out for about 30 seconds and comes back. Both before and after the incident I am usually at full bars.
I'm unsure of what EDGE is. The only things I control are the APNs I obtained from Rogers - one is just the standard one that gives me 3G and HSPA, and the other is LTE.
Dunno what else I can really do. I doubt it's my provider so it's gotta be the phone. Any other real troubleshooting steps to try, or should I just get this to Sony?

EDGE is 2G. so turn off LTE and HSPA+ and see if it does it.
I don't have the LTE equipped phone so I'm not sure if these hardware functions will switch on and off randomly.
It sounds like your hardware is switching between 4g and 3g. problem is that both wont work simultaneously, so you would get this drop off. solution is that build prop edit i gave you.
But then you'd have 4g on all the time. so if you don't want that then turn it off manually.
Try these.
Edit your build.prop file.
(do you know how to do this??)
and insert these.

that will stop hardware switching between 2g/3g/4g
as well as make it faster.
Settings->More...->Mobile Networks->Network Mode->GSM Only
You'll still have mobile data, but it will be SLOW. I think the top speed is around 400KB/sec, but you'll only use this to check if your signal is more stable without 3G/4G.
Tip: If you want to save battery and you aren't the type that uses a lot of mobile data, use EDGE (the thing i'm currently writing about). 4G uses a lot of juice.

Thanks. Just made the change and will keep an eye on it over the next day or two.
Just gotta say holy crap this Edge thing is SO slow. Even just loading icons on Google Plus or Youtube searches takes forever. A mobile speed test is showing about 133 kbps...
Damn... gotta come up with a better solution that doesn't require having slow as shyte data access
I'm trying WCDMA only to see how this might work. At least the speeds are more tolerable there.

Yeah, but keep using it for now. You're only checking if the signal drops while your on it, so I'm not saying that you should keep using it. It's only for a couple of hours. You can do it!

*sigh* I'll try
lol
EDIT. Nevermind the part below. I just kept trying more SMS apps until I settled upon GO SMS and it seems to finally be able to load photos. Damned weird the default one wouldn't do it
On another note, can anyone explain why the built in Messaging app has issues both sending and recieving photos? Plus there're a few instances where it says I've got a message, but I've viewed them all. I've even tried downloading a few other messaging apps from the Play store, and they can't seem to view or send photos either. Damned weird if you ask me.

I'm not using the stock messaging app. I'm using Hangouts as my main SMS app, but I didn't have any issues with it when I used it. The Android 4.3 update is released now, so you can update to it through PC Companion? Note that this will remove root and stuff like if you're rooted. If not, go ahead.

Sorry to bump an old thread, but I just want to say that I'm having the exact same issue. I thought it might have occurred after I installed a custom room but I'm now back on stock and still experiencing 4 bars immediately dropping to no service and then going back to 3 or 4 bars before slowly dropping back to zero. I figured it could be LTE, so I experimented with all settings under mobile networks to no avail. I try the same Sim in my note 2 in the same location and I have no issues. I believe this is an issue with the antenna or a general hardware fault. My phone is the c6806, originally on Bell but being used on Telus. I have already contacted Sony but they are giving me the runaround
Anyone know how the warranty is handled in Canada? Anyone else have this problem?
Signal issues
Sorry I'm restarting this thread one more time.. But anyone figure out a fix? I'm having the same problem on a brand new phone... I had the same phone before I lost it. Got it again but these signal dropping issues now . Never had these on my previous cc6806
