Samsung Galaxy S Duos 2 Review: The phoenix arises again

As the name suggests, the Samsung Galaxy S Duos 2 S7582 is the successor of the immensely popular Samsung Galaxy S Duos S7562. Despite of being an average phone the original Galaxy S Duos was sold like a hot cake in the market. Hell, it even sells now.

I didn’t like it so much as it’s not good at doing even basic tasks. But it was a hit phone nonetheless. So when the Galaxy S Duos 2 was announced I got excited.


Our Promise 

We review phones with an obsessive focus on the experience that really matters to you. We don’t care about specifications, we will tell you what you will really feel while using the phone. And needless to say, we maintain total integrity and truthfulness in our reviews.

Don’t Miss- Why We Are Different 


Intro_Samsung Galaxy S Duos 2 S7582

I was waiting to get my hands-on this phone since its launch. We received this phone a few days back in our office and I used for a couple of days.

I’ve been receiving requests from our fans to review it and now that I’ve used it for a couple of days I can tell you that it’s much better than its original version.

Here is its full in-depth review:


  • Plays HD videos and popular audio formats out of the box
  • Good performance


  •  Stale design and looks same as the original Galaxy S Duos
  • Not meant for high-end gaming
  • Average viewing angles


Box Contents

1. Handset, battery, USB cable, charger

2. Headset and warranty card.

User Experience



First Impression: Oh! Its just another Samsung Galaxy smartphone.

The Galaxy S Duos 2 is made out of plastic but hey, it doesn’t look cheap.

Sides- Fiber bezel with brushed metal finish

Back Panel– It is made up of textured plastic and has standard galaxy design.

Design Usability: Uninspiring Galaxy design but manageable in size


User Interface

The S Duos 2 runs on Android 4.2.2 JB with Samsung’s TouchWiz UI on top.  The tuchwiz adds a lot of new functions to the basic android UI and is very useful.

Homescreen: The homescreen can be configured from among the following 2 modes:
Standard mode & Easy mode

Samsung Galaxy S Duos 2 S7582

Themes: It doesn’t come with any in-built theme. If you are theme junkie then you better download them from the play store.

Lockscreen: The lockscreen can also be configured as per your needs. You can choose from different Screen lock types, Unlock effect and also get to select the shortcuts for lockscreen.

Smoothness to Operate– Very good. I didn’t experience any lag in the phone as far as the normal apps are concerned.



The Galaxy S Duos 2 sports a 4 inch TFT LCD display having a resolution of 480×800 pixels.

It produces pictures with rich colors and okay sharpness level but the viewing angles are not that great as the image loses contrast and the colors shift when you watch the display from an extreme angle.

The absence of auto brightness function will make you adjust the screen brightness when you change your surroundings or you are shortening the battery life.

The display is reflective and gets greased up in no time.

The phone doesn’t come with any screen-guard pre-installed so better get one first before using the phone.

Single handed Reach- Yes





Single handed Portrait mode- The keys are very well spaced and the auto correction does a great job at correcting the typos.

Dual handed- Landscape mode- The typing gets even better in the landscape mode.

Auto-Correction and Prediction Options- Yes

Continuous input: Yes

 Prediction: good, Auto Correction: Very Good




The stock browser has all of these standard options like pinch-to-zoom, double tap to zoom. Scrolling is smooth but is accompanied by occasional minor lags which are found in the entry level android smartphones.

Multi-tabs: Yes, incognito- No but Chrome is there to help

Pre-installed browsers: Google Chrome


Extra Features

The Samsung Galaxy S Duos 2 also comes with support for 2 gestures:

  1. Smart Alert
  2. Mute/Pause

Temple Run Oz runs smoothly only till medium graphics settings.

However light games like subway surfers run fine.

Default Apps- S Planner, ChatON, Dropbox.


BatteryBattery_Samsung Galaxy S Duos 2

The 1500 mAh Li-Ion battery did heat up a little during our testing but not too much.

On full charge the battery will get you through a full day of light to moderate usage. If you are power user then you better carry an extra battery/charger with you.

Final Verdict

S Duos Reborn

The Samsung Galaxy S Duos 2 is one of the best branded phones under 11k INR. It does what it is made to do perfectly. It is made for normal users whose main requirements include good after-sales support and an android smartphone.

There are some other phones from Lava, Xolo, Micromax, Karbonn etc which are way better than this phone but they all suffer from poor after sales support. Galaxy S Duos 2 is the first smartphone from Samsung which can compete with the phones from these local manufacturers placed within the same price bracket.

    which phone is best to buy under 10k.

  • PRAMOD says:

    Hi I have seen other video review like gadgets portal and others in which the available amount of ram after first boot itself and always shows under 250 mb and in your review it shows 327 mb. I want to know the reason behind such difference. Please comment

    • Anand Karwa says:

      Hi Pramod,
      I have posted what I saw in my test device. Those guys might have installed a lot of apps and set them to startup with OS.

  • Ela says:


    Please provide the exact information for below question. Hope it will help a lot of potential buyers to decide.

    1) Can we install apps on SD card?
    2) Will battery last for a day with the usage information given below?
    (3hrs phone call, mobile data on all time (2 email account and notification of few other apps like FB, twitter and whatsapp), 1hr of wi-fi usage, 2hr GPRS usage [wi-fi & GPRS off on rest of time], 2 hr browsing and rare usage for gaming and video)


    • Anand Karwa says:

      1. You cannot install every app on the memory card. The apps which require phone memory to be used cannot be moved to the SD card. You can also use App2SD application to check which apps can be moved to SD card.
      (You can move all the apps to SD card only after rooting your phone.)

      2. Well, it depends on your ringtone, display, vibration and other settings. If the data is off when not in use and that 2h browsing is done on WiFi and not on 3G then the phone should last for the whole day.

  • Juba says:

    I use samsung galaxy trend duos, I have difficulty in uploading profile pictures on whatsapp. Also, before I can download audios, videos or pictures on whatsapp, I need to mount an sd card. Is it normal?

    • Anand Karwa says:

      If you are seeing prompts asking you to mount SD card then you there is something wrong. Take a backup of your files, contacts, messages, calendar, etc. and perform a full system reset. It should solve the issue.

  • raghu says:

    Dear sir, I hv galaxy s duos 2 and I am facing bass boost troubles with music player with even high end to find No solutions. PLZ suggest to fix low bass boost trouble with s duos.

  • kp says:

    my cellphone samsung galaxy s duos 2 is getting hot after surfing internet after 5 mins, could u please suggest me how can i solve this problem..

    • Anand Karwa says:

      Hi Kp,
      You should uninstall all the apps that you don’t use and then check if it still gets heated up.
      The last option would be to factory reset it.

  • Bob says:

    Hi Anand,

    I bought a Samsung Duos and was wondering if you had any idea how you can delete the Double Tap when you make or receive phone calls, it is most annoying. I would appreciate your assistance.

    Cheers Bob.
