I have a problem with setting android to only use 2G networks. I can tick an option under settings "Use only 2G networks" but after i leave the settings menu it gets "unticked" again threfore i,m constantly on 3G which wouldn't be a problem but in the areas where there is no 3G signal android loses signal and wont connect to 2G network. I can turn off 3G under winmo tof orce android to only use 2G networks but it takes time. My question is can anyone successfully setup their android to use only 2G networks?
Same Problem
I´m having the same problem and for me it´s worse because it drain my battery really fast (don´t last more than 4 hours).
Could somebody please fix it as soon as possible because this way is really difficult to use android as main OS.
When I put a Sim Card that doesn´t have 3g I don´t have this battery problem.
I hope somebody could help me with this problem.
could someone please look into this? 3G kills my tilt realy fast too. this is the only thing stoping my from using android as my main os.

Try this:
$ su
# rwsystem
# nano system/build.prop
Find the part that says something about default_network=0. Try changing it to 1. Save with dpad-center+x, then y and enter.
# rosystem
Restart your phone to have it take effect. I'm currently trying out the value 3 which is "use GSM or WCDMA, whichever provides the strongest signal" and it seems to work better for me. Before I often had switched to Roaming after calls and somethings loosing connection completely, but I have only tested it for a short time so I'm not 100% sure if it helped or not.
Next release will include scripts to change this and some other things easily.
Oh, and the value 1 is supposed to be "GSM only" so it might help.

Kalt, should we change this "ro.telephony.default-network=0"? to "1"
If so, it didn't work for me . I'm still on 3G.

Yes that's the one. Well, getting information about the settings in build.prop isn't easy. I'm don't know if the information I found was a fact or just a guess.

HELP!!!
I have tried everything here and still no 2G. I love android but battery life sucks. There has to be a way to force 2G all the time. 3G is great but if batterylife will suffer so badly I want to turn it off perminently. Does anyone know how to do this? I'm using VaniljEclair RLS7c and I have been messing with the scrips in the update and still nothing after reeboot.

I have tried everything too with almost all builds (1.6 2.1 and 2.2). My opinion is that ro.telephony.default-network command do not work on Kaiser. If ro.telephony.default-network is removed from build.prop nothing happens. Maybe TelephonyPprovider.apk is something to do with 2G 3G switching.
Bump... Please someone help us!! There has to be some hack we can try.
Please help us!!!
I agree,
Would be great to be able to force certain networks. If you look at the power usage/ per network the faster the network the more power it consumes. I'd like to be able to by default use the low speed and switch it to fast when I'm really using the phone. My EVO has a 4G widget switch. If it didn't the phone would be worthless to me as 4G in my area is not great. 2hrs 4G on (with no 4g network) = -40% battery... Love to do the same for 3G as that would save "about" 20% more battery life alone. I might get a whole day of use without charging...

Very simple. You use file follow. You install it,only mark or unmark for 3G or 2G. I'm from Vietnamese. I speak E not very well. I'm sr if you don't undertand
looks like this is only for 3g-2g data connection.Discussion is about GSM -CDMA network

As far as i know apndroid disables both 2g/3g connections and we only need to block system from using 3g connections leaving 2g still connectable.
Has anybody seen this before?

I get the settings, but the problem is that I can't choose any - no matter what I choose it stick to "Unknown" type..

I've tried that a while ago and it didn't work for me.
I've bin going thru htcgeneric-ril.c (source of libhtcgeneric-ril.so), provided in another topic and noticed this lines:
Code:
switch (rat)
{
case 0: at_rat = "1,2"; break;/* Dual Mode - WCDMA preferred*/
case 1: at_rat = "0"; break; /* GSM only */
case 2: at_rat = "2"; break; /* WCDMA only */
}
Could there be a solution lurking in those lines to ongoing 2G/3G switching problem on Kaiser devices with Android?
Those look like the settings from the phone information screen in testing, it's certainly the right area to be looking in.
Question: who's gonna be brave enough to hack htcgeneric-ril.c and recompile that lib?
I already asked n2rjt to do it, if it's possible - still waiting for his reply.
Hey I just came from Galaxy S and there is a way to disable Hsdpa in there which improves battery life amazingly....
I was wondering if there is a way to do that in Desire? (for my city 3g speeds are faster than hspa for some reason)...
Also is there a way to select which band the phone is connecting by 850 vs 1900 ... or to see what it is using ?
any help would be appreciated
It's in the settings someone in network
There is also a widget to totally disable mobile internet which I use to save battery
Sent from my HTC Desire
Go to Settings > Wireless & Network Settings > Mobile Networks...
That's pretty much what you can do with the Desire as far as mobile networks are concerned. GSM phones normally switch to different frequency bands depending on where they are located and in the Desire I don't think you can select which one to go for (besides it's an unnecessary feature in my opinion)...it just does it on its own. Maybe there is an app around that let's you do this?...
As for viewing which band you are on....you can't do it on a standard ROM but there might be custom ROMs or an app that let's you do this.
Update: Some apps that might interest you => 4G, CDMA, GSM & Wifi Map Viewer from Sensorly.com
=> Open Signal Maps Beta from Staircase 3, Inc.
=> Antennas from mpoly
=> Quick Settings (maybe..)
mmm none of those do anything like it...
all those either just shut off data or turn it on... im not sure if anyone has used the galaxy s
http://forum.xda-developers.com/showthread.php?t=837716
this is what im talking about... saves the phone a LOT of battery by just forcing it to use 3g instead of hspa ...
i think developers can prolly make more sense of it.. i mean if they have a way.. there has to be one in other devices ...no?

Ah, so you have a Galaxy S.....unfortunately, this is a HTC Desire forum, so it would be better if you posted this in the Galaxy S forums. You may not find the answers you are looking for here as this forum mainly handles a different device to the Galaxy S.
What I said before is only applicable to the HTC DESIRE. I thought you switched to a Desire when you mentioned you came from a Galaxy S, but I was mistaken. The apps I mentioned as mainly for monitoring the 4G, 3.5G & 3G (i think 2G too) coverage. If you are looking to switch between them (i.e. turn HSDPA off and turn 2G on) I am sure there is a way to do so...on the Desire this can be done through the Mobile Networks settings...
And no, I'm not familiar with the Galaxy S....
no i had the galaxy s... (i posted that for reference as to how its done on that)...
and ya those apps just toggle just 2g vs 3g...
im looking for a umts vs hspa toggle... (3g vs 3.5g).... because umts takes way less battery than hspa does...
tried to mess around in the band setting screen but couldnt find anything
SOLUTION
what you need is to edit /system/build.prop file
here are my settings:
ro.ril.hsxpa=0
ro.ril.gprsclass=12
ro.ril.hsdpa.category=1
ro.ril.hsupa.category=1
after doing the and couple?... of restarts H icon changed to 3G and it really does save battery significantly and speed is pretty much enough for browsing or email
would have thought if battery life was vital then you'd disable data completely tbh
This is somewhat network dependent. Here in Sweden I know of one network that will have you at HSXPA (H) as soon as it is possible. My network on the other hand will set to 3G when WCDMA is detected and set to H only during data traffic.
And then G if only GSM is detected.
I disable data via widget if I want to save power even further. Not that it has that much impact. There is a setting under wireless and network > mobile network at the bottom : ativate mobile data (this is translated). This setting will force the data connection to be active even if unused. You have to experiment here what setting is best for your network. On my network, if I remove the tick here (data connection will let go if not used and reconnect when needed) my battery will drain quicker. Providers with other policies might give different result.

Thanks! Very useful! For me it was only necessary to change the "ro.ril.hsxpa=0" line, then do a couple of restarts (to make it clear, a single restart wasn't enough, HSDPA was disabled only after the second restart for me).
Hello guys,
I need some help here with my DHD. My serious problem is about its signal. I am in my home and i am talking on my DHD, but sometimes it loses the signal. In my house, the signal is very good, not always at 3G but at 2G it is always at full signal.. Although, it sometimes loses its signal and my call is closing.. By the way, to be more clear, when my call is closing i check the signal, and i see it to be full... At this step, when i am checking about the signal, sometimes i see the signal to drop down to zero, after 1-2sec.. But the other times it stays full.. But in both of these cases, my call is closing many times.. What can i do to solve this problem, anyone knows?
Thanks, and i hope to help me with this.
P.S. Sorry for my bad english guys And one more problem that i have is that my DHD few times, it lags, stucks, dont know how to say it, and in first case it unstucks afters 30-40 sec, or in second case it restarts..
AFAIK, the gsm antenna is located in the bottom cover that the sim and microsd is hidden behind. If the contacts inside dont make a good connection you will probably get lost reception from time to time. You could try another cover, or bend the two gold coated spring contacts near the simcard very slightly outwards to make the connection more reliable.

I tryed it mate, and tnx for your reply. But today in the morning, when i was talking on the phone, my call closed 4-5 times in a 20min call.. Dont know what is happening, but maybe anyone of you guys knows another tip to help me? Maybe any change on the software? And by the way, my phone had in automatic the choice about 2G/3G, but i changed it some days ago only to 2G because in my house the 3G signal is not so good always, and if it loses the 3G signal and it needs to change to 2G, the call is closing for sure..
I have the same problem with my DHD, I live in an area where the 3G signal is crap. I found that when running CM7 you can switch off the 3G and just use the 2G which helps. If you using a sense ROM you don't get that option which is a pain, so I'm sticking with CM7 for the time being until someone produces a workaround for the other ROM's.

Try your sim in another phone. If the signal is still bad you should try contacting your network operator and ask them if there are any faults or if they can do anything to improve your signal.

No sense is like CM7 (Cyanogen Mod 7). They are as close to standard google android with added features. Standrard android is found on googles own devices like Nexus and Nexus S. Although CM7 is based on AOSP (google it). Sense has a different (rosie) launcher and added extras included such as widgets, Icons, and other extra HTC only features. Look in the Desire HD andorid development thread for different ROMS with sense no sense.

I was using some times another phone but i didnt have this problem same as i have it on my DHD. Yeah, maybe i had it few times on my other phone but occasionally, and not so many times like these on my DHD.
I had the same problem. I had to order a new sim because my sim card was old and apparently wasnt very compatible with my DHD. I'd suggest getting a new sim from your service provider
Hmm leaked from my thumbs through my mobile device....

When u are saying that your sim card was old, how many years do u mean?
Cause i think that i have bought it about 4years ago... You think i have to ask for a new sim card with the same number or what??
Hello all, firstly i apologise if this has been answered before, i did search but couldn`t really find a definitive answer!
I have a HTC Desire which at the moment has Gingerbread (2.3.3) on. This is the one direct from HTC which i have restored via a nandroid to see if the problem persists. The phone is rooted and s-off (clockwork mod recovery) and i have tried out a few ROM`s but the problem seems to persist.
The problem is with the Network Mode function whereby you have the 3 options, WCDMA only, GSM only or GSM/WCDMA auto. It seems i have to have this option set at GSM only for the phone to function properly. If i set it to Auto it seems that as soon as the bars drop so does the connection and i am unable to make or receive calls
When on GSM only i can access the internet but obviously not 3G so i only get an E above the arrows.
I`m in the UK on Vodafone and my area says it has good coverage for 3G which i can confirm by using other phones.
Does anyone have any ideas on what the problem may be, i like my Desire and would love to be able to use the full potential.
Happy Christmas and New Year to all...
p.s. If you need more info, i`m only to happy to provide it.
What happens when you set network-type to WCDMA only?
Is your radio up-to-date?

What's your problem with WCDMA only? And which do you mean with Exgo? Please write the whole name.
a fix maybe
hi mattchur try this code as if you are making a phone call,*#*#4636#*#*,in there are a list of commands you can change gsm/wcdma,it may help you fella
Thanks for the replies guys, it seems i have made some headway into the issue!
I tried using WCDMA only as suggested by MatDrOiD (thanks for that) but the reception seemed a bit flaky...
Using the *#*#4636#*#* which i knew about (but thanks burty39) iv`e been trying out the different options (had a few issues with GSM/CDSM auto (prl) don`t do this ) it`s seems when i choose the option "WCDMA preferred" and things seem to work fine for now.
I`m getting an H (HSPDA) when connecting which is at least 3G i think and i`m able to make and recieve calls.
The network bars don`t seem to high though (2 or 3 bars), maybe i`m just in a poorish reception area despite what Vodafone say.
certified noob, is the Network app from the Market just a short cut to the above? Could you explain more about the Exgo thing please...
Cheers.
Did you check wether your radio is up-to-date?
Sorry Mat forgot about that, meant to include it in my post (bit to much booze yesterday).
Anyway i`m pretty sure my radio is the latest, details are,
Android Version: 2.3.3
Baseband version: 32.56.00.32U_5.17.05.23
Kernal version: 2.6.35.10-gf43272
[email protected]nd18-2 #1
Still seems a bit patchy now and then, if i select GSM only (EDGE) my signal strengh is -75dBm 22asu (full bars) and all is fine, if i stick it on WDCMA preffered (HSDPA) i get ~99-107dBm and 2-6asu (with 1 to 3 bars) and can occasionally access the net albeit slowly.
At the moment i`m just staying in GSM only, at least i know it`s working then.
It`s frustrating as i stick it on WCDMA preffered and one minute it`s fine, the next pages time out!
Cheers
No problem. Yes, you use the newest radio.
Any idea how to enter the *#*#4636#*#* mode in an Incredible S? I just get the Customize Quicksettings screen on this?

Hello all, I'm hoping somebody will be able to help. I've got a desire HD on 3 UK (I haven't contacted them coz tech support is useless and I don't want them to know I'm on a custom rom), running LordClock's ICS 8.6.1, My data works fine on 3.5g but as soon as phone switches to 3g I get no data at all. I've tried various roms I've Googled for hours and found no solution. I've checked APNs and tried various versions found on web, I've tried changing the WCDMA preferred option in hidden menu, I've cleaned and reseated the sim, and tried turning airplane mode off and on The annoying thing is data has worked on 3g on Ice cold sandwich in the past, I think v7.3. I was wondering if it had anything to do with build prop and have changed and added various lines but with no success. Any advice or suggestions would be greatly appreciated and thanks will be given to anyone who contributes. Thanks.
What do you mean by switching from 3G to 3.5G? There's only a toggle to switch between 2G and Automatic mode (2G/3G) in ICS right? How are you switching between the 2? Also what is this hidden menu where you switch to WCDMA preferred? (Just for my knowledge. I don't know about it). Does it work for you with different ROMs?

Hi sashank, I meant just that when I lose a 3.5g signal and it automatically drops down to a 3g signal I'm not switching it myself, and if u go into the dialer and type *#*#4636#*#* u get a hidden menu called Testing with gives u info bout network or battery, check it out, the WCDMA option is in Phone info.
Hi, I have exactly the same problem. just to clarify, I am on the 3 network too, and when I have H (HSDPA) signal, the internet works..and works well. however as soon as it changes to 3G..the internet doesn't work at all
you should consider flashing other radios
