[General Questions and Answers] huntercity:
it's false

it's possibile use only one sim in WCDMA but the 3G module it's available in either SIM

i did this tests :

SIM 1 GSM (no connection data)

SIM 2 WCDMA (data connection)

SIM1 e SIM2 enabled and in SIM CARD MANAGER i ENABLED the option "Receive incoming calls via other SIM card while using data service"

with this configuration we can always have data connection on and receive call from SIM1 or SIM2

the throughput of data connection is very slow :(

test 2

SIM 1 GSM (no connection data)

SIM 2 WCDMA (data connection)

SIM1 e SIM2 enable and in SIM CARD MANAGER i DISABLED the option "Receive incoming calls via other SIM card while using data service"

with this configuration if we turn on data connection on SIM2 we CAN'T receive call from SIM1

the throughput of data connection is better then before but again very slow :(

test 3

SIM 1 GSM (no connection data)

SIM 2 WCDMA (data connection)

SIM1 DEACTIVATE

with this configuration the device is like mono sim galaxy S

the throughput of data connection is good about 3mbit in download and 1 in upload

test 4

SIM 1 WCDMA (data connection)

SIM 2 GSM (no connection data)

SIM2 DEACTIVATE

with this configuration the device is like mono sim galaxy S

the throughput of data connection is good about 3mbit in download and 1 in upload

so...in conclusion....with 2 sim active the data connection is very slow...this device it's useless as dual sim :(
[General Questions and Answers] ferrazrafael:
summarizing, you need to put the sim you use the data connection on sim 1 slot, like a said
[General Questions and Answers] huntercity:
why did you say that?

in the test 3 i used only one slot...the slot2 and the performance was great

the problem is with 2 sim active not the slot1 or slot2

could you try to do a test and report the performance test?

thx,

Carlo
[General Questions and Answers] martijnn2:
Dual sim is working great .

only wcdma/3g is possible on one sim slot at a time.

Hey huntercity, I did the test on my GT-S7562L (same phone but for latin-america market), and got similar results. Transfer rate went from around 500kbps to around 200kbps.

as I understand, it really is a problem with the phone, I even got a message that I might have this lower transfer speed issue when I reactivated the dual sim option...

I don't believe Samsung has any interest in solving this, otherwise they would already have done it...

[General Questions and Answers] Codename13:
I have a Galaxy Ace II X GT-S7560M which is the same as your device but it has one aim card and my device is from Canada. I once had a problem like yours. I think the solution would be to have the phone display active (phone should not be sleeping). At least that's how I got my computer to recognize my phone. Keep the phone screen on until you're done with the file transfer. I think it's a bug cause by a memory leak, in which the phone forgets the USB transfer service should be active. I don't think there are any file transfer related wakelocks..

[General Questions and Answers] Codename13:
I personally don't like scripts because a lot of them don't actually do any good. But I have modded my device's ICS firmware to include the CRT-Off effect, 4 way reboot menu, status bar customizable lidroid toggles, and more. Currently, I'm trying to make the 4 way reboot menu mod on a newer build of my device's firmware (from Panama) that is more smooth and responsive. Well, at least I'll attempt so when I get back home to a computer to mod firmware. Anyways, I don't recommend that we try to exchange .apks from each other's firmwares despite our devices having close resemblances internally and externally because of your device being dual Sim and my device being single Sim. Though if I downloaded your device's firmware, I could do the same mods for your device! I'll consider it when I get home in a week or two.
[General Questions and Answers] 25vikasp:
Ya it's really hard to decide which scripts are good.I used v6 but its not good for my phone so i removed it now its thunderbolt and some build prompt tweaks..my phone and ur phone had same configuration just a dual sim;maybe ur tweaks are good for me.can u share it here if possible..thanks for ur reply and help..

1. Uncheck 'auto-reboot' in odin.

2. After odin shows 'pass' first open the USB cable, then eject the battery.

3. Put the battery back in the device, power-on the device and you're done.

[General Questions and Answers] sachinkh:
My friend i can help you...your cwm recovery is overwritten by the stock recovery every time during boot up ...so to prevent this you have to rename a file in etc folder in your phone memory...file name is install-recovery.sh....rename it to install-recovery.sh.bak .

For renaming purpose you have to gain superuser permissions and you can use Root explorer or any other app which can go to system files.

find this file install-recovery.sh. it is in etc folder..rename it then flash the cwm again ..its done now your cwm is permanent.

My phone switches off after Screen Lock

I tried to google and find a solution to this problem, but so far I have not been able to find any.

My phone simply turns off after I lock the screen, regardless of battery charge level. But I am able to keep it turned on and unlock screen when it is connected to my PC via USB cable.

I have updated the Baseband version from S7562DDBMD1 to S7562DDBMG1 using Samsung Kies, but this has not helped in any way. I also reset the phone to factory settings before I went for the update.

I do not aim to root my phone as its just been 2 months since I bought it.

Any help would be hugely appreciated.

Download the OTA 4.1 Poland firmware & flash it through Odin. That's it, you are good to go. Then you can root & install CWM.

You will only receive OTA`s for the rom of your region, if you want that just flash the Indian JB rom and do not root, If you are rooted OTA`s will not be installed as you have a custom recovery.
