[Q] Turn off 3G on Samsung GS2 - General Questions and Answers

Hello,
I have a small question that I don't have the answer for ...
How to turn off 3G on my GS2 I have tried alot but still couldn't get it fixed ?
Thanks

I don't think it's integrated anymore, but there's a way to turn off data altogether when you're not using. Bring down the notification bar and scroll to the right for the toggles.

Really, I can't belive that Samsung forgot about it !!!! in this case can you give me please a complete configuration to save the battery life as it's not convinient to me at all
Thanks for the quick reply

I have the Same problem too, I swore I would never buy another Samsung phone after the captivate but I decided to take a chance on this and it's the same ****ing **** all over again. I love everything else about the phone but the useless ****ing GPS... no wonder u.s. carriers are hesitant to get that **** galaxy s2. If I spend my money I expect **** to work, mother **** Samsung!

I have Samsung Infuse as well and the GPS is so slow. Is that Android issue or hardware?

there is no gps problem. this happens after you flash the infused 1.5 rom and others because it has altered settings and there must be a conflict somewhere. you can fix it by entering lbs test mode from the dialer (sgs tools will launch it but it doesnt seem to make the settings stick, you can check if the settings stick by reading /data/gps/secgps.conf in a text editor) the dialer code is *#*#3214789650#*#* it sometimes doesnt work if gps is disabled. then toggle the agps mode to something else and exit lbs, then reboot the phone. reenter lbs from the dialer toggle the settings back to stock and clear gps data. then exit lbs(use the back button not the home button. i think it writes settings on exit), see if the settings stuck (/data/gps/secgps.conf) and reenter lbs and and get position test.
it is a pain but wont normally be a problem if the phone was never messed with. gps issues are a common complaint on any smart phone regardless of manufacturer.. my iphone 3g would not work under cover, that meant no car navigation(not that the app was available for turn by turn at that time), my friend complains about his droid incredible, my other friend complains about his lg, my other friends complain about various blackberries. it is a normal complaint.
I have to admit. I've only used gps a handful of times, but I've yet to have any issues with it. I'm running Bionix Infinity at the moment and have seen nothing but excellent gps.
Wow realy infused rom issue lol? I had this phone stock for a week and gps was horrible before anyroms period if anything is a samsung thing. I came from iphone 4 which.had an impecable gps, therefore no need to blame this on any rom ive tried them all and stock its all the same

while it is true there are bad units, this can be said about any manufacturer. what i am refering to is a specific situation that i have encountered when using roms that have the modified settings to use the nokia supl server. though this server works amazingly well for some reason when you flash a rom with the changes pre set there is sometimes a conflict that prevents a lock even though 10 or more sats are in sight with strong reception. one of the users above said they say "all gps working" i am assuming that means they can see sats but get no lock and i posted a way to resolve this if it is rom related. if you have a bad phone and are sure of it im not calling you a lier, get a new one! if you dont trust samsung well the lg thrill is coming soon.
Im not sayimg that bro.i love the infused its not the roms though.it may effect settings when u flash roms but its easy fix. I get locks all the time some fast some slow but 90% of the time it locks. In a house maybe mine does but no lock at work, so yea areas ,weather, signal,device, location,etc all play factor and for me the better battery charge I have the better the locks. Im only sticking up for devs this has nothing to do with specific roms

Did you flash the gps tweak addon when installing the Infused ROM? When i did, i noticed that the settings were still on stock settings in LbsTestMode. After changing it to jz3's required settings, the lock on gps was a lot better, but accuracy is sometimes off.
Here is his thread:
forum.xda-developers.com/showthread.php?t=1107860
If you dont know how to get to LbsTestMode, i downloaded an app called Any Cut. Long press on an empty area on home or whatever. Then shortcut>any cut>Activity>LbsTestMode
After that, refer to the link above and start on step 2 (if you already have the gps tweak addon)

This unacceptable because my old HTC g1 got a lock instantly inside or out and not to 20 m like this garbage but down to 3m !!!!!

yeah i didnt mean to point the finger at the developer either. the mod works very well for many people but for me and a few others when reflashing you have to toggle things back and forth to get it to work, i also make a few other changes afterwards but experience varies so im not gonna push my successful settings on people. as for your experiences, well my phone is impecable anywhere i go in any weather so there may be an inconsistancy in the antennas or something. the gps works under cover on my infuse better than my iphone but oddly not better than my captivate. my captivate is less accurate and gets slowwer locks but can find me inside a building with a metal roof and in the basement of my house, this is from a phone that is supposed to be notorious for gps issues, but this is only after i changed a few settings and updated the glgps daemon with da_g's mod and did a lot of figuring out what doesn't work.
Yeah i started to see up to 8+ satellites after the fix. Before wouldnt even LOCK on lol.

Do u know of a better fix than the one in our dev section?
Sent from my SAMSUNG-SGH-I997 using XDA Premium App
I'm on my 2nd stock Infuse (only rooted) and each had the same pathetic GPS/Software lack of performance issues. It is driving me insane. I assume, based on forum threads, this is a SAMSUNG specific problem.
My old iphone4 GPS was basically perfect with almost instant satellite fixes which meant I used it for running, biking and motorcycling (in addition to car use on trips), photos, etc. Can't do this with my Samsung Infuse.

it's all subjective. it's kinda a ymmv situation but the extent of what i do is start with the mod from jz3 and delete one line in his gps.conf file that says "DEFAULT_USER_PLANE=TRUE" there is no need for this (and other additions in his file) because it will be set in secgps.conf by way of lbs test mode anyway and i dont use userplane so it might cause a conflict.
the operation mode is set to msbased and dynamic accuracy is turned off ( i just do this out of habit, it "seemed" to work on the captivate)
supl server is set to supl.nokia.com and the port set to 7275 with secure socket off and agps mode set to controlplane
i have no way to know why this works any better but it "seems" to work for me. also after some googling i found that control plane can be used for emergency location for 911 calls which is a good idea if you like hiking or 4-wheeling which i do.
i offer no guarantees that this will work better for anyone but it seems to work on my captivate and my infuse, the captivate has other mods to the jupiter.xml and an updated glgps deamon thanks to da_g's mod. the infuse should be up to date on the glgps daemon from the factory and the jupiter.xml is stock.
i can get as low as 4m locks and get locks in as few as 4 seconds to about 20-50 meters initially quickly coming down to 6-8m. most locks take under 10 seconds.

Hrmmmm....no noticeable issues here. We used the apps gps status and faster fix on some evo roms to quickly connect and it seems to work on the infuse.

I find "the grip of normality" is the best fix. Seriously, holding it normally and in most scenarios there is no problem. You have to TRY to get it to drop out, and that'll only happen if your wifi signal is already weak.
Most custom roms also have a fix which lowers the threshold at which the phone drops the signal however. I ran the phone on stock rom for 2 months and didn't have one dropped connection. Its an awesome phone.
My only gripe with it is you have to run gpsfix every couple of weeks if you want a GPS lock. A problem with the a-gps chip though so not a HTC sense our android issue. Mildly annoying when you are sat in your car waiting for gps to lock, but at least its fixable, and forgivable considering how good the rest of the phone is.

Aaaah another one coming from G1
Can def. recommend the DS!
Didn't really have any probs with the wifi issue...
Well, i using a TGU case and everything, never had issue with wifi disconnection... thats all i have to say
When using my phone normally around my house, the signal stays between maximum strength and -1 bar strength with my normal grips (normal single hand portrait and dual hand landscape view).
I can force the issue and using a tight double handed grip in portrait view and reduce the signal to one bar but I have been unable to cause my connection to drop.
There's a fix from gtg465x which lets you stay connected to the wifi even when your signal is low. This doesn't solve the "death grid" but it improved wifi a lot for me! source: http://forum.xda-developers.com/showthread.php?t=1051674
As said before, there is a somewhat hidden setting to get the wifi to perform a bit better and at least not dropping the connection. Go to: Settings -> Wireless and setworks-> Wi-Fi settings, press menu, choose Advanced and check the Best Wi-Fi performance checkbox. Note that as it says in the menu itself, it may consume more power. Isn't there too much topics about this in this forum? Please someone put them togethether with a sticky and delete my double posts. Thanks.

[Q] GPS simply will NOT lock on, never!

Edit: Might be stupid question, but does the Infuse have to be carrier activated for GPS to work? That is what Samsung Mobile Live chat is telling me, supposedly. If that is true, that is ridiculous that the GPS can't use satellites alone, or satellites+Wifi, and relies on the mobile network...
Background info: I am rooted, using stock ROM 2.2.1 froyo. Don't have my Infuse activated yet over AT&T, don't even have a SIM card in it, have Wifi connected to try to help GPS data, but no Mobile network.. Location and security: Use wireless networks and Use GPS satellites are both checked
Hi guys. I've seen many threads on here, threads on other forums online, and other misc tutorials googling GPS fixes for the Infuse. I cannot for the life of me get the GPS for the Samsung Infuse 4G to lock on to any satellites! It it crazy that so many people out there are having GPS issues. Everything I have tried does not work for me. I've tried replacing the gps.conf, secgps.conf, and changing the LBSTestMode settings to about everything I could find on the Internet, even trying them on the original stock settings to:
Code:
Operation Mode: Standalone
SERVER: www.spirent-lcs.com
PORT: 7275
I've tried using the supl.nokia.com and the supl.google.com and nothing seems to work! This is crazy. I am almost at the conclusion that GPS on my phone is just totally screwed up. My Sprint Samsung Epic locks onto GPS in only a few seconds, I even took the Infuse outside for about 5-10 minutes and it never locked on. It will get up to 5 satellites in view, but GPS stays yellow and doesn't lock on, and they never go over to "in use"
See attached picture of what I'm referring to: http://i.imgur.com/6Asod.jpg
If anyone has any suggestions I would really appreciate it. I don't wanna send in my phone to Samsung and wait a couple weeks to get this fixed, if they do fix it.
Thanks for any advice

Ehh I would, but it's my dads phone.. just didnt wanna put all sorts of custom stuff on it and have to update it, the only reason I rooted it was trying to use one of the GPS fixes I've seen around online. Maybe I'll try to remove root and send it to Samsung for an RMA. : ( boo

Hi,
In case you still have the Infuse 4G, I was having the exact same issue. The following fixed it:
Step 1. Follow instructions for Google Specific v3.1 build http://forum.xda-developers.com/gal...s-patch-galaxy-s-ii-3-1-2-2-to-rapid-t1447599
Step 2. If you're regulating voltage to extend battery life, increase the voltage at all frequencies you're using.
Step 3. Let your GPS test app run for 10 mins. or so for the first time after reboot. Next time, you'll get faster fix.
Results:
I started out same as you: 3 or 4 sats in view, no fix, never. I was in a world of pain.
After Step 1, I was viewing 11 sats, using 4 or 5 sats, accuracy = 100 feet.
After Step 2, I was viewing 11 sats, using 6 or 7 sats, accuracy = 30 feet.

[Q]3g is popping on and off like it wants to start up but doesnt and no connection??

i have no clue what going on here.. but i dont have any data... but voice works fine.. ive done multiple reboots.. running opensensation..
anyone knows whats happening?
im running the 30.00 prepaid 5 gigs of data plan
You can change your data connection . Example my device always wants to go to edge, which is really slow so I lock on to wcma only which is 4 g. You can try the different connections by going to #*#*4636*#*# it will bring you to a menu you press phone information, then press your current connection and another menu will come up with available connections, pick the one you want and scroll down to refresh . I'm not sure this will do the trick but if you have any available connections you can hook up this way. It depends what's available in your area .I was going crazy with my device always going to edge so Iocked onto 4 g this way. It works for me. I do hope it helps. Are you rooted and running custom Rom? If you are and this method does not work perhaps try a different radio? Best of luck hope this helps some

It's *#*#4636#*#* sorry I had that wrong in my first post

yeah that still didnt work.. and this is really troubling me.. i posted in the opensensation thread..
I had the same problem with roms based of CM9. The only solution is to back up everything (titanium backup helps with backing up apps), wipe and re-flash.
No need for wipe.
Just re-flash the current ROM. You will have to apply all your Mods again, but the rest of the data will remain fine.
(I had the same problem about two days ago)

Radio problems do not come up all of a sudden.
Yeah i fixed it.. I had to backup and then restore my tmobile stock rom.. Then restore my cm9 backup.. Seemed to fix it but wow that was weird..
Its happend to me after i flashed somthing. All i did was put it in Airplane mode and rebooted. After reboot turn off airplane mode. Got everything back.

need help

i recently flashed cm9 onto my sgs4g and now when i set my phone to vibrate mode it changes itself into silent or ringer, and im also having the problem that its now showing 3g instead of 4g like it should, before i flashed cm9 it showed 4g, so could it be the area im in doesnt support 4g or could it be something else? or would going into recovery mode and selecting "fix permissions" fix the problems im having? any help would be greatful.
and big thanks to the developers who made cm9 possible on the sgs4g, its outstanding and cant wait to see what comes next, and big thanks to all the others that help out.

1. I dunno, maybe its a bad flash? Did you wipe your data/cache and factory reset before flashing?
2. Thats not a bug t mobile doesn't actually have 4g the rom will show and H instead of 4g. You should be getting the same data speeds as before

i did everything needed 2 flash the rom, i have 2 manualy set it 2 vibrate then use the vol up/down 2 get it into vibrate mode, not understanding why i have 2 do that every time i reboot my phone or every few hrs due 2 it changing on its own.
as for the 4g, when i am at home it shows 3g, but if i leave and go 2 were theres more towers it shows no 3g/H or anything

Ok...
1. On stock roms it stays at 4g constantly (But it goes to 3g sometimes without notification) CM9 shows you whats actually happening.
2. The vibration thing I had the same problem, i'm currently on aokp but if I get a chance ill look at it ( I don't remember atm) I will pm you the answer.

ok thank you digital, i wasnt sure why it kept saying 3g (after letting it sit in certain spots it started showing H), as for the vibrate thing ill keep messing with it
no problem! Now for the vibrate thing I have figured it out, when you go to set it when you're cycling through the settings 2 of them will vibrate I didn't really pay attention but one will vibrate and work the other one will vibrate once and then remain silent.
straight from the dope house!
sweet, thanks again digital! didnt know there was 2 modes 4 the vibrate
