Review: Samsung Galaxy S Duos - GT-S7562

Why to Buy:

S Duos is a good phone in Dual sim functionality and its Android 4.0 operating system is great which is also upgradeable to latest Android 4.1 Jelly Beans.

Why to Avoid:

Its screen resolution and display can be a reason to avoid. It lacks with a dedicated camera key as well.

Our Take:

Samsung Galaxy S Duos is a better option for people looking for Android phone with Dual camera and Dual Sim functionality. It is a good mid-range phone with many good features pre installed. But, its weak display and screen resolution is not good.


Rs. 17, 499

Detailed Review


The Samsung Galaxy S Duos is a best Dual Sim phone among all others in this category and price range. It’s fast, slim and solid and most importantly it appears same as Samsung Galaxy S III Mini and is even considered as the smaller version of Samsung Galaxy S III. It has a standard 4 inch screen size with TFT capacitive touchscreen. S Duos sizes 121.5 mm, 63.1 mm and 10.5 mm dimensions in height, width and depth, which is simply superb with dual sim functionality. It weights 120 gm. and the all plastic body is well fitted in the device.


Below the screen is a physical home key along with back and menu touch keys. And on the bottom of the phone has a USB/charging connector with a mouthpiece alongside it. On the top of the device is a 3.5 mm earjack whereas, the left side gives you volume controls and lanyard eyelet. The right side holds the lock/power key and microSD card slot, but, there is no dedicated camera key on the phone. Above the screen is a front facing camera with light sensors and earpiece. The overall construction of the Galaxy S Duos is great and it’s handy too.


Samsung Galaxy S Duos primarily runs on Google Android 4.0 ICE (ice cream sandwich) operating system, which has done full justice with the device and to its buyers. And more importantly it can be upgradeable to the latest Android 4.1 Jelly Beans. The phone is power packed with 1 GHz cortex A-5 processor and Qualcomm MSM7227A Snapdragon. When tested, the browsing on this interface with power packed processor and RAM was a better experience. The speed was good when on 3G and multitasking to swapping applications was smoother.


For everlasting experience, the Galaxy S Duos comes with a standard Li-Ion 1500 mAh battery which goes well with the device. When tested, battery performed excellent results on 2G and above average on 3G. The stand by time delivered was up to 550 hours on 2G and up to 450 hours when on 3G whereas, the talk time was up to 12 hours on 2G and up to 8 hours on 3G. So, we can say that Samsung galaxy S Duos ensures you good battery results.


Galaxy S Duos comes with tremendous 5 megapixels main camera with auto focus and LED flash and it also has a VGA front facing camera. The camera quality of Samsung Galaxy S Duos is great. When tested, the outdoor images captured were rich and clearer in colours and the camera worked quickly and hardly took a second to be ready for next image. The Galaxy S Duos camera supports JPEG, PNG, GIF, WBMP, BMP and AGIF image type. The indoor shoots were even good. The Galaxy S Duos camera has a 2592 x 1944 image resolution. The images from front camera were average. The weak point of this phone is its display of only 480 x 800 pixels.



The Samsung Galaxy S Duos comes with in built memory of 4 GB. The memory can further be extended to 32 GB using a micro SD card. The phone supports 768 MB RAM, that helps multitasking and swapping applications easily.


The Samsung Galaxy S Duos has not compromised with its voice/sound quality. The sound quality when tested was good with headphones and even when on speaker mode. The Touch Wiz music player is multi functional, the sound enhancing DNSe technology and 5.1 channel virtualization gives you better music output. Samsung Galaxy S DUOS supports AAC, AAC+, AMR, AMR-NB, AMR-WB, eAAC+, I-Melody, IMY, M4A, MIDI, MP3, OGG, SP-Midi, WAV and WMA audio formats. Like other galaxy phone, Galaxy S DUOS also has a Stereo FM radio with RDS. The video quality of this phone is wonderful. It features 1080 pixels full HD recording and playback at 30 frames per second. The video call quality from its VGA front facing camera is good but the sound quality drops down if you hold it at a hand’s distance. It supports MPEG4, H.264, H.263 video formats. When tested, the video captured from the camera was really in superior quality and gave 480 x 800 pixels resolution.


Dual SIM service of this phone allows you to receive calls while you are connected to the internet or even if you are already talking on the phone on the other SIM card. The Samsung Galaxy S Duos is pre loaded with SNS integration. The Social Hub includes all major social sites like, Facebook, twitter, You Tube, Linked In and many more. The much hyped ChatOn service enables single and multi-person conversations, multimedia file sharing and even more. Galaxy S Duos is featured with Samsung Kies 2.0 and Kies air. The newly introduced Kies 2.0 enables the Samsung Galaxy S Duos to sync with a computer using a Wi-Fi network for PIM backup, subscribing to contents, and multimedia contents sharing. And with the Samsung Kies air you can connect with any browser’s address bar without a Kies program through the web browser to manage all sorts of information and multimedia contents on a larger screen. Wi-Fi direct, NFC, Voice Calling and All Share are also featured in this power packed phone.



The Samsung Galaxy S Duos is certainly the best phone in this price range and segment. It offers long list of in-built features/applications that exist in all latest Android phones. The big 4 inch screen and TFT capacitive touchscreen is amazing and offers great display. The powerful RAM and processor gives hassle free browsing experience. Overall, the Samsung Galaxy S Duos is a good phone in almost all aspects but few hardware and design faults are its weaknesses. We give this phone four star rating.

I had purchased Samsung galaxy duos smartphone GT-S7562 in September 2012 and from the day one the handset is giving below problems. I have written to CEO office for 4 times but all the time they as to visit the service centre. I had submitted my phone thrice to service centre and even they are convinced that the handset is defective but Samsung is just killing time by asking me to visit service centre again and again. Please go thru the problems with this phone and do not buy this product 1) Operation is extremely slow 2) Phone hangs repeatedly 3) Sometimes the phone does not display the caller name when the phone rings 4) Data upload and transfer is very slow. 5) Touch screen operation is not effective 6) While exiting any application the operation is very slow 7) Sometimes when i go to message box, i can see the contact no.s only. After few seconds the names of contacts start popping up 8) Facebook application also operates very slow on the mobile. It keeps showing loading before displaying details on the screen 9) After taking a photo or video when i want to review it, it takes longer time to load. 10) I have deleted lot of applications from my cellphone due slow operation as well as transferred all the photos, videos to external sd card but there seems to be no improvement 11) while viewing a photo or video there are lot of instances when i tilt the camera by 90 degree, the video or photo does not timely rotate on the screen 12) while using fb application when the details are displayed and i want to scroll the screen, the response is lethargic.

I purchased this phone(SAMSUNG GALAXY S DUOS GT-S7562) in Navrati i.e. in Oct. I downloaded so many applications but after download i felt the phone is too slow then i thought to transfer the apps to external micro sd card so i purchased the external sd card. When i tried to move apps from phone to sd card then the move to sd card is not coming in my phone. I tried so many times and even i downloaded many apps to move apps from phone memory to external sd card but i did not get success. Please can anybody tell me that i am the only person which is facing this problem or more people are also facing this problem? Is there any other way to move apps from phone to external sd card? Because phone operation is too slow because now there is only 300 MB is free in phone memory. So please help me in this matter.

The device is fine for a budget andriod of this level. The price by the way has come down to some 13k (approx)... Couple of irritating things: 1. If you play temple run 2 then you need to turn off wifi, gps and mobile data else when you get a new email or notification the phone will struggle to perform and 2. there are some performance issues which make you wonder if the processor is actually a 1ghz one or not. Overall, if you are keen on an android and have a bit of patience then the phone is decent. I wont say good because as time goes by, there is a lot of lag that develops in the phone. Examples of this are seen in the most basic operations: swiping left or right to call or message takes time. contacts open slow. swiping between screens is slow.
