Faulty SIM 1 Slot

Hi. I am an owner of a Gold Platinum 32 Gig Samsung Galaxy S6 Duos, bought locally. Ever since my purchase (24 May 2015), I've been using only a single sim on the SIM 1 slot. Everything's working fine, until the start of this week, when I've noticed that my cell signal has been fluctuating. I've been having difficulty sending/receiving calls/SMS.

At first, I thought it was the fault of Globe. So, I pestered them for a good 3 days. To no avail, the situation did not change. Tried isolating the pronlem by inserting my sim to a different handset, and using a new sim on my S6 Duos. Even with a new sim inside the S6 Duos, the problem persisted. So my heart sank at the thought of a busted phone. Next, I tried transferring my sim card to the SIM 2 slot. Guess what? There were no problems with the signal! I could go on using my phone on SIM 2, but the pronlem is that it does not support LTE. :(

Anyone else experiencing this? Thanks.
[Galaxy S6 General] flogger:
First of all, SIM 2 slot also supports LTE. You just have to change it in settings. You can only use LTE in one of the slots, but it is up to you in which.

Second, what you might be experiencing is if for example it is actually in LTE, you might have a weak signal, it doesnt mean there's a problem. Try to change manually to 3g instead of LTE and see if the reception is better. Then you would confirm that is a network coverage issue.
[Galaxy S6 General] hanpo84:
the problem is that I can't root with pingpong method, so another root methods too risky for me when I dont have stock rom.

have you seen "XXV"-code in your csc packege?

have anyone try CF-auto root or another root methods ?
[Galaxy S6 General] redarceo:
Thank you so much for your clarifications re: LTE usage on either SIM slot.

I have new developments -- even with my sim in SIM slot 2, my signal reception isn't fairing well and it only displays "Emergency calls only". You think my phone is faulty?
[Galaxy S6 General] flogger:
Which model exactly do you have? 9200 or 920FD?

And in which country are you? You might have the wrong model for the wrong country....
[Galaxy S6 General] flogger:
Nop. The 27 my package has is in the picture below.

Xxv is contained in the OLB package.
[Galaxy S6 General] redarceo:
I have the G920FD variant. This is so weird, I switched my sim back to SIM 1 slot. It's working fine again... I hope switching and re-switching wouldn't be the remedy for this. So no problems on your end, yet?
[Galaxy S6 General] flogger:
No problems so far. I also have the FD variant because Im based in Europe and only that model supported all the frequencies for this.
[Galaxy S6 General] lge73:
I have 920FD variant and unfortunately the 3G- 4G is weaker than other phone reception (my old HTC M8 Dual SIM! If i use in places where signal is strong, no problem everything is ok.In case of weaker signal strength (4G-105dB, 3G-110dB) signal started fluctuated, no net connection, and often have call drops! I m on ODE firmware (Apr 20).

Unfortunately, I can not decide if my device is faulty?
[Galaxy S6 General] redarceo:
Good to know! I hope you won't encounter problems similar to mine. Thanks for your help!

Hi! I think we share the same problem. But I first noticed this with SMS, and calls. Then I started noticing it with data connection as well. Same as yours, the problem isn't evident in areas with really strong signals. I think it may be a faulty batch of phones. Maybe a future firmare update can fix this?

I also tried removing and re-inserting my sim card and I think it solved the problem (maybe temporarily). Maybe you can do the same.
[Galaxy S6 General] mjne_19:
My computer wont detect my s6. Can you please help me.

I hope is software problem, and 5.1 firmware will resolve our problem. In SIM1 slot i have data card, and in second voice. Frequently, although have 3-4 signal strength in status bar (SIM2 -GSM), I'm not available and switched voice mail!!!
[Galaxy S6 General] hanpo84:
I've got the same problem with 3G signal, i read in phone guide that duos version is weaker than mono version. I try to change origin CSC into my region (XXV) and hope that solves 3G signal problem

Also, my computer doesn't detect my version S6 too :D
[Galaxy S6 General] TheEndHK:
It is possible to flash the single sim rom with the chance of success if you keep the baseband/kernel but then only one sim will active. I just need root, custom recovery and tools to deodex it myself via ADB. Custom roms is welcome but not real necessary for such a beast.

---------- Post added at 03:24 PM ---------- Previous post was at 03:15 PM ----------

What do you mean real dual active? sim1 and sim2 talking or dialing out at the same time? I don't have a second nano sim so I can't test it but I think it's only call forwarding.

Both sim could receive 3G/4G as reported on HK forum. When you select sim1 3G/4G then sim2 will switch to 2G, later on if you select sim2 using the 3G/4G data service and this time sim1 will switch to 2G.
[Galaxy S6 General] Hemant:
Like You I am also waiting for root so I can install adblockers and greenify and other root applications. Also might cha ge dpi. I am also not worried about the Custom ROMS but once rooted we can't officially update the system.

Thanks for confirming about the dual sim. I always thought sim 2 was 2g and as I am travelling between China and hk these days I keep changing my main sim to sim 1. If I knew before that sim2 can also use 3g or 4g then I won't swap Lol. Aware that only 1 3g or 4g is working at the same time.
[Galaxy S6 General] gpx:
With dual active you can receive calls on both sims without call forwarding and with no delay getting the call from the second line. In this case also you are not charged with the service of call forwarding from your provider. There are not many dual sim phones out there with dual active function for example mate 7 .
[Galaxy S6 General] TheEndHK:
I may not root it soon since it is a very expensive phone. yup, I miss adaway and greenify and I real want mod camera. You can still update it but it will be a bit trouble, you got to use odin to flash any new rom(usually you could find all official firmwares from Samsung on net) and root and install custom recovery and deodex via ADB and restore everything from titanium backup after all.

---------- Post added at 03:53 PM ---------- Previous post was at 03:46 PM ----------

I'm not sure if it is real a call forwarding. Call forwarding is almost a free service now in HK so I don't worry...lol... I guess the newly HTC Desire 820/826 is also a real dual active phone with dual 3G/4G on at the same time.
[Galaxy S6 General] BLueBLaze100:
Since I bought my g3 dual sim I can't use a phone with single one, definitely s6 is the champion of 2015 and I'm planning to get one soon.

The problem is only 32gb available right now and absolutely not enough for me, i wonder if they will release 64g any soon !

Availability in Europe (UK)?

Hi all, does anybody know whether (and if so: when) the dual-sim Galaxy S6 will be available in Europe? I'm in the UK and would really like to order one!
[Galaxy S6 General] Smartphoner:
This is my video of the SGS6 dual sim variant I've just bought. (The phone's origin is Hong Kong). It's not called duos by the way.

Samsung Galaxy S6 dual sim (SM-G9200): http://youtu.be/iuijjxZ9sY0

My 1st impressions on it after using Z3 dual...

1- 32gb is just not enough, I really miss the sd card expansion option. I wish they would release a 64gb variant soon. I will definitely switch.

2- Battery life is not good as compared to Z3, dunno if it's because of the dual sim effect or maybe because the battery performance didn't settle down yet.

3- 4g capability is available on both sims and that made me really happy as I may use mobile data on sim 2 sometimes.

4- The overall software and hardware performance have been improved compared to past Samsung devices.
[Galaxy S6 General] unosison:
Has anyone been brave enough to root and install a custom rom on the dual sim s6? I'm getting my pre-ordered phone this weekend from Samsung Philippines, and it's really a big deal for me that I will hopefully be able to flash custom roms on this bad boy.

I really don't care about the dual-sim functionality of the phone, one sim will be good enough for me. :)
[Galaxy S6 General] DrearierJester1:
I just got my S6 from Smart Communications, and it has DUOS written at the back of the phone below the samsung logo. Here in the Philippines our phone model is SM-G920FD only PH and Pakistan has this model.
[Galaxy S6 General] salman_83:
Is there a 64GB version of the SM-G920FD? And how can i order the phone from Qatar?
[Galaxy S6 General] DrearierJester1:
Duos has 32/64 .... No idea though where to get it near your location.
[Galaxy S6 General] Hemant:
I have the rooted the duo phone. However touch on TWRP is not working yet and have to use volume keys for now.

I am not sure if the international custom os would work on our phones even if its means disabling dual sim function. If this works then we will have many roms. However if this doesn't work then afraid we have to take help of Chinese users who have already released custom roms. I can't read Chinese but I might see if I install the rom or not as they you can choose to install hk (my phone) or Chinese rom at the time of installing. This info was shared by one of our kind users [MENTION=3125604]iamthe[/MENTION]HK who speaks both Chinese and English language. So thanks to him for this info.

[Galaxy S6 General] TheEndHK:
I've heard unconfirmed news S6 Duos 64GB will be available later in HK after 1~2 months. I not rooted yet to keep the warranty bcoz I'm thinking to sell out for exchange to 64GB later but I doubt I still have money bcoz the 64GB should be very expensive. The S6e 64GB got US$115 over S6e 32GB here.

http://www.techbang.com/posts/16280-photofast-i-flashdrive-pen-drive-test-ios-android-mac-system-to-sweep-the-undifferentiated-transmission

The current solution to me is iFlashDrive USB OTG(MicroUSB, USB, IOS Lighting). Above link is in Chinese but with detailed pictures.

I actually more prefer to carry a small wifi microSD reader out so that I can give it a 128GB sd(Again, above link is written in Chinese with good pictures). But S6 wifi seems consuming quite a lots of battery, at least it happened on my AOD3 firmware.

I also have an idea to sell out my S6 Duos and buy an imported ver single sim S6.... :D

http://www.soului.com/forum.php?mod=viewthread&tid=20683&extra=page%3D1

This site made custom roms for HK ver of G9200 and latest ver is updated to AOD5. Pre-rooted, knox removed, init.d supported.
[Galaxy S6 General] DrearierJester1:
Quick question, basically here in the Philippones we only have the S6/S6 Edge Duos, I got mine from an operator, can I flash the s6 firmware of the factory unlocked to operator locked phone? Both phones are dual sim.
[Galaxy S6 General] TheEndHK:
Samsung got official unlocker on my G9200, not sure about your model(HK S6E no dual sim, very wired). You can't flash single sim rom to dual sim, if you exclude the kernel and baseband then it might be possible.
[Galaxy S6 General] DrearierJester1:
I see. Thanks for the input. But can I flash generic Philippine firmware? I checked on sam mobile, and noticed PDA is the same but different CSC. This is for both Generic PH firmware and the firmware pre-installed on my operator locked phone from PH as well. Can I flash that?
[Galaxy S6 General] Smartphoner:
This could be a temporary solution for the storage and transfer of data...

https://youtu.be/LsOZeQlrdbo
[Galaxy S6 General] DrearierJester1:
Hahaha dont like the DUOS logo as well. Got mine from Smart 64gb. The demo units doesnt have that lol so we were misinformed a bit lol...
[Galaxy S6 General] FeliXdk:
Frequencies?

In Denmark we use 900/1800 Mhz for 2G, 900/2100 MHz for 3G and 800/1800/2600 MHz for 4G.

As far as I can see from the spec-link earlier in the thread, for the SM-G9200, 2G looks covered but for 3G 900/2100 is missing and for 4G 800 is missing. Does anyon know of any other markets with the S6 Duo released, that support the same frequencies as we use in Denmark?

And in that case, shouldn't I be able to just import the phone and use it locally? Unfortunately Samsung normally do not release Duo models here :(
[Galaxy S6 General] Smartphoner:
From where I live 3g bands are 900 and 2100 and it's working fine and I saw 3g with my own eyes. 4g is working with no problems also.

Here are the specs for the G9200
[Galaxy S6 General] prinzhernan:
I have 2 networks on mine. Sim 1 smart sim 2 globe. First sim uses data, second one for calls. Both work fine and signal is good. Even in 1 bar signal the Internet is fast. I think the problem is just your network and not the phone itself...
[Galaxy S6 General] hanpo84:
but with the same sim and the same location, my ip6 get better signals and surf internet without problem not like S6. Maybe the baseband of that phone not compatible with 3g band in my country.
[Galaxy S6 General] redarceo:
Oh, wow. Are you also having problems with (non-data) signal? I currently cannot rely on my S6 Duos in making calls and texts.
[Galaxy S6 General] HYKwan:
how can i get gapps for those roms?
[Galaxy S6 General] Fatadxb:
I have 920FD got the same problem with 3G signal
[Galaxy S6 General] lge73:
Try to switch on GSM only, had same problem as you in 3G and 4G network

---------- Post added at 07:56 AM ---------- Previous post was at 07:44 AM ----------

GSM, WCDMA and LTE bands are standard, here in Europe using B3, B7, B20 for LTE. Compared the signal strength with my old Htc M8 DS, i get almost similar values, BUT S6 constantly fluctuates!!!

Tried a lot of firmwares (single sim version) BTU, XSG - OE3 baseband but same result! Waiting 5.1.1, and hope will resolve our problem!
[Galaxy S6 General] prinzhernan:
It's also possible that both phones measure signal differently. From my understanding the bars don't follow a standard...
[Galaxy S6 General] TheEndHK:
I think the 52root comes with Gapps and there is also some flashable gapps.zip for Chinese rom but I forgot the link.

SVA paid rom got G9200 and 920fd ver and the G9200 one is USD15.

So, the G9200 indeed got many custom roms with 2 free and 2 paid counted. At first, I was thinking to get a single sim for flashing custom roms but luckily I decided to buy G9200 at last bcoz I want dual sim but it turns out to be G9200 got as many roms as single now.

you're lucky when you could root with pingpong, my version still not supported. what kind of bootloader version do you have?
[Galaxy S6 General] redarceo:
Your suggestion was very helpful. Tried switching to GSM Only when I am in areas with very poor signal reception, resulting to my S6 Duos not being able to send/receive SMS/calls. In GSM only mode, I get to send/receive SMS/calls. The only downside is when I have to use mobile data for browsing, since I have selected GSM only. I hope Samsung releases a new fix for this, real soon. I'm actually tempted to bring my phone to the Samsung Service Center. :(

[Galaxy S6 General] arbuckle:
I ordered the G920FD from Jadopado, it took less than a week to arrive. Although Jadopado provided the correct and honest value of the product on the packaging (unlike some other companies who try to assist their customers in dodging import duties and VAT), customs didn't notice it and the phone was delivered without customs charge.

I see 5.1.1 is rolling out. I unlocked my bootloader, so my G920FD doesn't receive OTAs anymore. If there's anyone out there with a clean factory image of Android 5.1.1 for the G920FD I'd be very grateful. Thanks!

I ask the question to Jadopado and its strange they told me the 920FD only works on 3G network in UAE. I request them to confirm if LTE will work in european countries but They did'nt confirm.

IS there anyone who has buy the 920FS 64GB Model on Jadopado and working on LTE band in europe ?
[Galaxy S6 General] flogger:
If it's the 920FD then it should work fine.

I have that model and it does. Already tested in Portugal and UK.

In the UK is a bit flaky because O2 or Vodafone only does LTE in one single frequency but the model 920FD does it fine while the 9200 doesn't have that frequency. In Portugal is a lot better because a single network does lte in 3 bands, so signal is way better.

That's weird. Maybe it's just missing info. The 920FD does lte 4g with European bands.
[Galaxy S6 General] Smartphoner:
Don't worry they are missing info. Just check your bands. Both sims support LTE separately altough they told me no.
[Galaxy S6 General] rahularora1:
I ordered through jadopado as well however the specifically wrote to me to say that this model doesn't support European LTE frequencies! Obv cancelled it then.

So it means its the 9200!
[Galaxy S6 General] rahularora1:
The model is listed as 920fd though on their site
[Galaxy S6 General] flogger:
Aa I said before, either the specs were wrong or then its the model name its wrong. If they told you it doesn't do European bands ita the 9200 otherwise would be 920FD.

Thats the difference. Samsung doesn't produce different 920FDs with different bands.
[Galaxy S6 General] filtrat77:
I order it to Jadopado, I will let you know for me if its the 920FD it is great but if its 9200 its ok as its also working with some european band... so I assume it should be fine anyway
