Android 7.0 beta on SM-G935FD Duos - 2'nd SIM question

Anybody tried Android 7.0 Nougat on G935FD Duos and can confirm that 2'nd SIM can be 3G/2G or still 2G-only?

One lte n one 2g only

Single sim + Micro SD
So, there will be no issues if I use one sim card with a memory card, right?

:good:

Thanks, VoLTE is one issue which i also concerned . so it is better to wait for official OTA.

I have a issue with 2nd sim slot too, I can't use 4G in second slot.
1st slot 4G + 2nd slot (3G/2G) => OK
1st slot 3G/2G + 2nd slot(4G) => 2nd slot only use 3G

In my country (Thailand), G935FD can use 3G network on sim2 even on Marshmallow 6.0

What kind of rom and csc code are you using? ?

@romeokk - are you sure, you have got G935FD and not G9350 (with Snapdragon) ?
Can you show printscreen with software info? Which security patch level?

Any Australian users tired this rom? Does it work with any carriers prefectly?

Here:

Thanks! it seems, that some country variants already has got update to enable 3G on the second SIM. I wonder, if the rest of G935F firmware variants will get this update too.

@romeokk - One more question: could you confirm, that it's possible to force 2nd SIM to use 3G only? Is mode "3G only" available on 2nd SIM settings? My goal to achieve is: 1st SIM on LTE/3G/2G and 2nd SIM in "3G only" mode.

I can absolutely do that. Since im using my phone to reply, its not convenient to upload a picture to confirm.
One thing I should mention is that after the phone has been upgraded to use 3G on sim 2, 3CA (LTE carrier aggregation using 3 frequency bands) no longer works in sim1 when sim 2 is inserted, even 2G only is set on sim2. The phone works on 3CA only when sim2 is not inserted at all.

Can single sim be flashed with dual sim firmware?

As the title says, can you flash the single sim version of S8/S8+ with dual sims version?
Are there any differences in hardware?

The firmware the duos model uses is the same as the single SIM model. The firmware detects the extra hardware can installs SIM manager.

You can't enable dual SIM on a single SIM model because it's missing hardware for the second sim

The 2nd imei is missing.

Hello.
Its not possible do to this, because today i try to make this and the firmware detects only the micro SD and one SIM card.
But the dual version SIM i think its possible do detect 2 card sim and micro SD.
Sorry for my english...i am portuguese and some times i dont remember some words.

Yes Its work make Single convert to Dual Sim.
BUT you cant use Sim 2 , they have no Number (000000000000000/07) its invalid.
only FD version have Sim 1&2 IMEI

So its possible to flash the duos firmware, but because there's no second IMEI it wouldn't work?
And if you purchased a hybrid dual sim tray, (which are readily availible) you would still have the 0000000........... for the second sim Correct?? And if you had a spare IMEI for the second sim, then how would you make the second IMEI work? Is there a IMEI flasher program for samsung phones??
I know there's one for MTK devices, so where's the sammy software program??
Surely this must be able to be done. If the mate 10 pro can be converted, the why not the s8 or even the s9/s9+??

Following.

Ok so what I understand and could be wrong. Is the hardware is there to read either if you look at the hybrid trays they are setup to read either 2 sims and no sd card or 1 SIM 1 sd.
So bassicly it comes down. To if that is true. For all models.
I have seen settings with 0000 imei for SIM card 2. But the option is there so what ever needs to be done in that case can be done. But of coarse I'm not getting Into imei options on s8. But they are possible. So it could be possible.
So bassicly some one needs to order the hybrid sim tray. Get the aluminum ones. But then try so see in hidden menues in settings and such see if detection of second sim is even possible.
So to test the one who does it at worst out a couple bucks for a tray. Of coarse check hidden menus.
First before flashing firmwares. Th3n after all that. Easily slide the tray in just for caution. No jamming as not to possibly damage anything.

IMEI Guru LLC Service tool can write a second IMEI directly to the system.

Doble SIM?

Hi guys im from mexico
My question Is very simple, i just bougth this Phone but only has 1 SIM port. When i check the SD port saw the port for sim2 but isnt functional. There s any form to mke the SIM cards Work at the same Time? Is because the firmware or hardware?

Carrier Agrregation supported on both sim slots?

Hello All,
I want to know if carrier aggregation (4g+) is supported on both the sim slots. I have seen 4g+ on my primary sim few times, but never saw it on my 2nd sim.
May somebody please confirm this?
Thanks

You can only get 4G+ active on slot where mobile data enabled.

Is 2nd SIM slot working for you on Pie?

Hello, I wanted to use dual sim and MicroSD at the same time, so I bought a device like this, and it didn't work. So I tested my working sim with the second slot and it couldn't be detected! On Android Pie here, with W350AWM20d: can somebody check if their second sim slot works with android Pie? Thanks.

Do you have a dual SIM variant of the V35? Otherwise the 2nd slot is microSD only.
I'm not aware of any dual SIM card V35, except possibly the Brazilian version? I don't know much about that variant. If anyone knows of any dual SIM V35, I'm curious.

I have a dual sim variant and I tested Korean, US Amazon, and US Google Fi Pie kdz versions and all of them don't use the second sim of the hybrid sim slot: Logcat shows something like 'MaxSim 1'.

What is original variant model number of the V35 you have? The one you say is built for dual SIM card? Why don't you stay on that firmware then, if dual SIM card is intended and works for that variant?
If you flash other non-dual SIM variant V35 firmware (like Amazon, Google Fi), the 2nd slot is going to be microSD only as those are NOT dual SIM card V35.

I have LMV350AWM, so I think that's AT&T. Oops, it does have a slot for the second SIM, so I thought it supports dual SIM. Looking at LG v35 specs online, it does seem to show that US variants don't have dual SIM. I guess I made a mistake there.
So, anybody know of a good working external Bluetooth SIM adapter for Android?
