Fixing Signal Issues (3G/H Switching) - Galaxy S II Q&A, Help & Troubleshooting

Hi
Does anyone know how to fix this issue? I am in a good area for signal and with previous phones am consistently on H. With my S2 it frequently switches between 3G and H even if it stays in the same spot. It will do it every few minutes.
This is causing havok when I try and tether and my Transformer and laptop keep getting signal interruptions.
Does anyone have a fix? I have Fast Dormancy disabled and I'm aware there may be some other engineer menus that have signal settings in that might work?
Thanks
Paul

Interesting.. And I thought it was just my network vodafone
Mine also switches between G/H/H+ all within 5 secs... yeah 5 seconds and it is kinda annoying.
Are you on GIFFGAFF as stated on you profile? or other network? cause I thought if might have do to something with vodafone..
Otherwise may be its something to do with the hardware settings, I too would like to know the answer

I've kept mine to use WCMA all the times...

Yes, I'm on giffgaff.
Glad its not just me. Maybe the antenna is a little too sensitive.
Anyone know the secret code to get to the GSM/UTMS bits?

This thread has lots of codes, if any help i have no clue which might help us

OK. Found the 2263 code but that seems to want to enable/disable actual bands.
Am I looking into it too hard!?

Now, for me wouldn't 3G and H/H+ both be considered as WCDMA under Mobile Network Settings? G and E would be GSM right?
If that is the case, staying on WCDMA wouldn't fix the problem.

Your phone shouldn't lock onto a H/H+ signal unless it has started to download data. That's how the protocol works.
If your phone is sitting idle it should be on 3G.
You should only get H/H+ when your phone is actively downloading.

OK. So how can I stop it flicking between the H and 3G. For instance when I am trying to stream it will get interrupted, or if I'm wirelessly tethered?

i'm from tunisia and have the same pronlem here.
Please developers help us to get rid of this 3g/h issue.

Guys,
I got the same problem here i n Brazil using a VIVO carrier.
I set in CONFIG -> WIRELESS AND NETWORK -> MOBILE NETWORKS -> NETWORK MODE -> WCDMA ONLY
I don`t know why it worked but now its working fine.
Could you test?

No problems to report in Amsterdam.
I'm biking through the whole city to get to work, no disconnects using TuneIn or Google Music. Provider is Vodafone, HSDPA+ all along the way.

Its Android issue
Think when iPhone, Windows phones have not had this issue, wat else other than Android. I have tried 3 different handsets. 3 different network - 3, O2 and Vodaphone. All has same problem. Android is the only thing common. I have been scouring the internet and posted everwhere possible since Dec 2010 from when I became Android user. There is no solution. Everone seems busy making their own Android versions and apps. Result there is no basic data and voice stability on Android. Have been relying on my decade old treo to receive n make important calls. Wonder where this is going. My heart n soul seems to sway to the iPhone lately. Atleast wat they give works well.

Its Android issue
BTW those config settings are useless too. I have even used the code to get into hidden menu and change config but no use. It's the same issue. From H to 3g and from G to E I gsm.

Sorry for the question, but whats the problem with switching? I have the same thing but is not a problem for me.

Nobody should get worried about that switching, THIS IS NORMAL!
H/H+ is an high speed 3G protocol.
Basically:
1. 3G means DL 384 Kbps tops. The modem is under 3G signal most of the time. Whenever something on your phone starts checking/d-loading it communicates at THE BEGINNING under 3G protocol. Also, long ping time> 210 ms.
2. HSDPA max 14 Mbps/HSDPA+ can go as high as 42 Mbps ( topped only by cell tower). If there's need for large packet data or shorter ping time, IT AUTOMATICALLY SWITCHES TO H/H+(IF AVAIL). Hsdpa consumes more power and it's a communication protocol. When connected under H/H+ error correction bits are transmitted along data stream. It's like switching your home wifi on b/g/n. ...or like the automatic gearbox going to overdrive.
If you see a lot of this switching it means there's a lot of downloading/uploading going on.

I have it switching too between 3g and h on o2 and its making the internet so unstable you cannot do anything at all. This is certain not normal as the switch happens every second and continues to do so until phone is off

Mine is also switching to 3G once connection is idle for about 3 seconds. So far no problem and it uses less power than my SGS1 for browsing since my SGS1 doesn't switch to 3G when idle.

Mine is no problem between this signal switching, check your area or check your country maybe too much communication devices there so that's why it is distorted. Just use the common carrier with plenty of cell sites for a good signal of your phone.

What do i need to dial to fix it to 3g only from 2g?

Why so slooooow? (AT&T 3G/HSDPA question)

Hello all - I don't know if there's any answer to this or not but thought I'd throw it out there. I updated Android myself to 2.1 since apparently AT&T doesn't feel the need to. That has been a fine experience and I've experience nothing negative aside from the wireless network speed. My phone now always has the H (for HSDPA from what I understand) instead of of 3G, but downloads, web browsing, and YouTube are all way slower than they were before. It takes 10 - 15 seconds to download a 750k app usually. I have ran the speed test app from speedtest.net and its results confirm this by showing 44 kbps downstream & 750 kbps upstream speeds.
Is there anything I can do to fix this? I know that HSDPA is supposed to be faster than 3G but this is unbearable - I am almost tempted to use EDGE exclusively because that is all I pick up at home (EDGE service that is) and I get better performance when using the browser than I do with HSDPA (although that is probably more mental than anything since when on HSDPA I am sitting there staring at the phone thinking "What is taking so long!" and when on EDGE I choose something and then don't worry about it for a few because I know it will take some time.
Thanks for any advice!

This is probably a network coverage issue and nothing you can do about it from a phone standpoint.
Ha! I love the first response had a joker pic because I was thinking of the joker when I wrote "why so sloooow".
Anyways when you say coverage what do you mean precisely? do you simply mean at&t hasnt done enough in my area for hsdpa to be effective? I do always have a full 4 bars of strength on it pretty much.
Thanks!

Yes, I mean AT&T. Having four bars means that you have a good signal. It does not indicate however how much bandwidth AT&T has allocated to that particular area/tower.
Think of it like a wireless router at home or office. On your laptop or computer, you see that you have a strong WiFi signal but, that does not mean that you have a fast connection as that depends on your DSL/cable connection.
Get my point?
Got it, that's what I feared. So in essence by improving my phone with 2.1 I screwed my phone (currently) with hsdpa

No, it did not screw your phone. Your phone is innocent here. It is probably the network. AT&T may have a problem in that area. Did you try the speed somewhere else?
Nope, haven't tried it anywhere else. I didn't mean screw my phone, what I, meant was if at&t is not so good with hsdpa in my area I am stuck with those speeds until that is resolved because I can't force 3g (my speed when I had iphone 3g was usually around 1 mbps)

I am on att also with the 2.1, luckily im in an area where i get around 2mb/2mb sometimes faster, sometimes slower. Did you try the setting in wirelessnetworks/mobile networks/network mode/ tick wcdma only if not on H. could help not sure, just a thought.

Your phone automatically switches between H/3G/E where available. I also have AT&T and have debranded my phone and did not notice any lag.
your problem is AT&T.
H is higher than 3G. if you got problems with it it`s because the signal is strong enough to use H but it preforms worse than 3G (cunfusing ah?!)
Well I was outside of my town the other day, in the country and noticed I was in hsdpa somehow so I ran a test and out there I was getting on average about 3.7 mbps. I guess where I am most of the time just isn't an optimal spot. Thanks all for the responses!

H+/3g Delay

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
rooted or not
ps. wrong section btw...

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.

Why is Edge faster than 3G or H+ (see edit)?

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.

[Q] Phone Switching Between UMTS and HSDPA

Asit says in the title.This constant change between the two network types causes data to be slow and timeout quite a lot as well as drain battery. Even watching low quality youtube videos is impossible because of the switching. I'm on the current CM10.1 build right now. Is there anyway I can just stick to one network type instead of it switching every second? I've tried going into phone information and set it to gsm only, wcdma preferred, etc. But it also just goes back to gsm auto (prl). And finally the weird thing is that there will be moments of time where data can be consistent (for like 5 minutes) and then it'll revert back to being slow.
Ive read in older posts (early 2012) that going to build.prop and changing ro.ril.hsxpa or somethinf like that helps. I can't find that so I'm wondering if theres another way to keep it at UMTS or HSDPA and NOT have it switch.
I'm on the Wind Mobile Network right now with baseband 1.15 if that helps. (I'm also a noob who can just flash stuff and new to this phone so go essy on me ^_^)
They are the same network. The phone just switches from hsdpa to umts when data is not in use to save battery. But hsdpa+ is just a higher speed version of umts, just like edge is a higher speed form of gprs. So That is not what is causing the time outs. It's probably just had network where you are. Mine switches between umts and hsdpa+ all the time, and my connection never times out.

Yes I know they're supposed to switch but that's the thing; even in standby it keeps switching constantly almost every other second causing battery drain. And the reasn why I'd prefer just hsdpa is that data is consistent on it whereas umts just times out on me almost everytime or rather when the two switch. Is this just a network issue?
I think it is just a network issue, as with tmobile as soon as the phone calls for data, it goes to hspa and there is not lag when it switches.

Are you talking about the 1.15 version, cuz I've already done that and the problem persists.
Quick question, I've opened up BetterBatteryStats and over a course of 7 1/2 hours idle, under partial wakelocks, google checkin service has had 967 counts, alarm manager 723 and a couple days ago RILJ and sdio dmux were up there. The difference between then and now is that I've had wifi. Is that anyway related? I don't wanna give up hope on this phone because I like it despite its poor battery life and this radio

I think you should download Greenify and hibernate your apps. That saves tons of battery. It looks like you're getting wakelocks which are causing the drain.

Signal drop out issues - Please help

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!

It seems to happen on a frequent basis. At least a couple of times a day when I happen to be paying attention to my phone.
I've never actually used stamina mode, and it's always been off.
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.

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?
:good:

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.
___________
ro.ril.hsxpa=3
ro.ril.gprsclass=12
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=20
ro.ril.hsupa.category=7
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
______________
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
