I have face promblem with my phone Phone is switch off while I am using net
so so bad. do not buy this phone it is a waste of a HUGE amount of time and money. too slow, not enough memory, closes apps on you, redirects you to the internet, battery life only lasts a couple hours, bad quality camera
This device is a so good but this version so old please gave up loli pop version
This "phone" if by far the worst smartphone I've ever held in my hands. Every action takes for ever and three days. Not one single app works properly, and sometimes one can't even pick up the phone, because until the phone builds up the screen, the caller died of old age. This phone is so useless that it doesn't even serve as a coaster, because the glass would fall off. Piece of sh.., that's what it is.

deepak, 05 Jun 2015Don't buy this phone
If you will buy this set, you will experiences the following issues:
1.... moreHave you given your Samsung s duos 2 for service to the above problems...
How much it cost for service and what services that mobile required...
Me too same problem...
That is a good phone with a good screen. .. But it has a old is Android 4.2.2 ... Plz give the KitKat update and I will be happy...
I have this phone for 1+ year. This is is a brilliant phone overall.
I would recommend it to anyone. I like the size of the phone, it fits info my pocket nicely. It also has dual sim and it does work well. For instance, if you receive message in goes into one folder, but it has a small  or  to indicate if the call came on Sim 1 or Sim2.
Phone clarity is great.
Apps run well and have never had issues. However, The amount of memory is miserable. You do need an micro SD card to transfer larger apps. However, sometimes it is a bit of a juggling act. I do have a lot of apps installed e.g. Camscanner, Adobe Acrobat, Dropbox, Evernote First Aid, Flash light, Google, Google Maps, Map my Run, Mini vMac, OfficeSuite, Outlook, TuneIn etc...UBReader, Whatapp, YouTube, TrackId etc...
The battery is removeable, which is brilliant, as some phones you stuck with the battery and batteries do not last forever!.
It also has an FM Radio, which is great, as internet radio is a choppy.
I have dropped the phone a couple of times and it has survived my torture!
The Camera could be better, you need to adjust the metering and learn the settings.... It does have a camera 'flash' which is pretty powerful.
I have run multiple apps, for instance Google Maps (for car navigation) with Music and it has been able to cope multiple apps, without problems. As well as GoogleMaps with TuneIn Radio (Internet streaming heat up the phone, but it does survive my punishment).
