Damm Samsung, my S6 Duos still haven't received Marshmellow update (android 6). Still on 5.1.1
It`s perfect!!! Everything work as it shod. No problem with signal strength, no problem with voicemail, no problem et al...so, wen you are writing your comment`s please be sour that you new what are you doing with phone. S6 duos, generally s6, is one of the best phones on the market! Both sim`s are active in the same time, signal strength is great, camera rocks, fast charging doing great and if you are not satisfied with this phone...than what to say...
Signal Strength is very weak especially when you select 3G or 4G on any SIM.

I have a very strange problem and I've tried 2 different SIM and carriers already. The phone has signal but calls go directly to the voicemail. I also don't receive text messages. So it's like is not even on. If I try to make a call, I can do it with no issues. And after doing this and for a few minutes, I can receive calls/text messages. Anyone else has this issue?
The 3g problem is present in other too. So it's not a samsung problem.

My samsung s6 duos have a problem. Sim card manager has a sms sim selection, I select it to sim 1.Before type a sms I should change to other sim (sim 2) in sms screen.But after adding some attachment it changes to the (sim 1) selection of sim card manager.

I have been using this Samsung S6 Duos for quite some time now and problem would be overheating. Then when its overheating theres like a moist inside the glass back case. Which alarms me because of exploding Samsung Note 7 and S7. Also, my charging pin is defective in which its not charging fast. Tsk.
