Does anyone know if there are apps or modules for the following problem; I want the phone to stop searching for 3G or 2G networks when the screen is locked? Because when I don't use the phone, I don't really need a 3G network.. and therefore will probably save some battery? So when the screen is locked it should use only 2G network, and when it's put on again it has to start searching for 3G or 2G networks.. any ideas?
That's interesting, its a good idea for an app if anyone can do it

I found an app called timeout3g.. but that kills all data when the screen is locked! So apps like whatsapp doesnt work anymore.. But seeing all these reactions it is not that interesting?:S
Isn't there anybody who's interested in this?
i own a samsung galaxy s2 ordered from uk,
everything working fine except for this serious issue that i have been trying to resolve till now.
i have a monthly internet subscription from my carrier and it always been working fine on my iphone ( i mean here connecting through the 3g network ). but in the S2 .. i have to use Edge to be able to access the internet ( the mobile network mode must be set to GSM only ). whenever i switch the network mode to GSM\WCDMA auto , the 3g icon appears but when it tries to connect to internet, the phone automatically switch to Flight mode and i loose the network signal. and this happens all the time. till now i am only able to connect to the internet by switching the mobile network mode to GSM only which only uses Edge network .
i have tried every possible thing to resolve this issue but nothing worked for me. please help
What country are you in? What carrier are you on? What bands do they use?
location location location.
Where are you from?
And what frequency does operators in your region operate.
just curious, have you tried hard/factory reset?
i am from saudi arabia and i am using Mobily network.
mobily is using HSDPA network as well as Edge network.
i did a software reset and still the same issue.
phone information:
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
crazy idea - is there any blocking going on in SA or with that carrier? Have you used another not carrier supplied smartphone successfully on that network?
I have been always using their 3g network on my iphone. And still there network only on edge connection on the s2. What i have noticed is that the saved apn sometimes shows up and sometimes disappears

Hi, very similar issue here.
For this four days since I have got my GS2 everything was just fine. The data connection and 3G speed was great. Yesterday, all of the sudden all got crappy. Could not display any web pages. It starting to display page but after few seconds pop-up window appear which say "Data connectivity problem. The server failed to communicate. Try again later"
Interesting that my gmail, market, xda app working fine as normal.
I'm in Ireland on O2 now.
Baseband version I9100XXKDH
Kernel version 2.6.35.7--I9100XWKDD-CL161513
Build Number GINGERBREAD.XWKDD
Can someone help to solve the problem, please. Is it possible that something with the hardware is wrong? Broken?
I'll perform the factory reset and will let you know.
i just managed to flash my device with the latest EXE1 dated May 3.
and i am still facing the exact same problem.

Maybe we should ask for replacement...
I have same issue, and for Ihrrob, your other application are working fine because what i noticed on my mobile that 3G & 2G connection is there but not permenant that's why WIFI hotspot always disconnect and VOIP applications are not working.

You are right the 3G/2G connection is there but not permanent.
If I press the Internet icon the home page, which is 'Google' appears (sometimes) immediately. I think this is because the page is very light. If I try to open a regular page it loads 1/3 of the content or nothing.
i just hope it is a software bug not a hardware problem
Type on the dialpad *#*#4636#*#* and force the phone to HSDPA only on the dropdown menu. This is a hidden menu on the phone.
Isn't this carrier related?

Unfortunately not.
I have spoke to the rep in the store. They reset all settings for me but it didn't help.
Just to double check if he wasn't wrong I've put the sim card in to my N900 and all data worked fine.
Bad, bad...

I'm on Mobily network in Riyadh, and 2G/3G is working fine for me. I stay on 2G most of the time to save battery, but have tested 3G and got around 3mbps.
I have the same Baseband, Kernel and Build number (rooted)
Are you using "Market Enabeler"? It can change your APN settings, and you need to restore the provider setting.
just rooted my device.
still same weird issue.
issue again: simply whenever my device tries to connect to H+ , the device automatically enters flight mode and automatically disable flight mode so that the signal bars come back without H+ and when i check back the saved APN i see nothing there ( thought i was there before ). and this strange behavior disappears when i switch the mode from GSM/WCDMA auto TO GSM only .. after i do this the device connects regularly to Edge network and i can browse the net.
so basicaly for me i will be only able to use the device on Edge instead of HSDPA or 3G.
im really hoping for help from here because i don't think i will find any help outside of this expert community.
regards
try to make it on obligatory 3G (WCDMA only) and check if the problem still there ..
still same problem juffo
i have noticed that another post are poping up talking about almost the same issure.
i hope a new firmware will fix this

Come on.. I'm not a newbie. I know all the settings. I have posted this question because after all the settings correct, still I'm getting this problem.
Hi everyone, i've a little bug .. When i'm on my 3g data, everything fine, but when i'm moving place then it switch itself to 2g because of lower signal my mobile data network just stop working, it shows that i'm on Edge (the little E next to the signal bars) but i've no internet on my mobile, i have to switch off completly my mobile network then switch it on again to make it work .. still on 2g because of low signal..
The things is that when i'm traveling in train, i'm on 3g then it switch itself to 2g, and that's very anoying because i've to switch off the data then re-enable it to continue surfing ..
Thanks in advance for your help !

Please can you try and say if it make the same ?
3G spends on the area in which you are. If that place doesn't have 3G then you will get 2G.
edge is slow as ´1990s modem´s internet, thats why is no internet

Yeah i know but you didn't understand what i wanted to tell..
Just try, when you have 3g (H) go to settings and enable 2g only, this will change your mobile network from H to E (which is normal) but when you're in E, you won't be able to have the mobile network internet, to have it again, you will have to disable mobile data, and re-enable it .. until then you won't be able to have internet ! So not even push notification ! the signal bar in quick settings will remain "orange"..
But if you disable mobile data and re-enable it , you will still be on 2g, but you will have internet ! even if it slow (because of 2g, which is normal too)
Bump..

Hello!
I have a problem with LTE in my device. When I have it in 3G mode internet works ok (but it's 3G). When i have it in LTE/3G mode first it connects to 3G, next it tries to connect to LTE but fails and it's out of reach for few seconds, and then gets back to 3G. I figured out that it isn't SIM card issue (it works with other devices). I also checked that this phone supports 4G bands in my country. Is there any way to fix it?
Check your apns you may need change or make new one.
