On top it has 3.5 mm headphone jack and IR Blaster. On right it has power button and volume rockers. On bottom it has USB type-C port, speaker and microphone. On left it has SIM tray and a special key which we can customize according to our choice.
 
At back it has dual 13MP rear camera along with dual LED flash. It has a rear facing fingerprint sensor. The build quality of the phone is really good. Overall there is no complain regarding the design of the phone.
 
Display
 
 
 
Micromax Dual 5 has a 5.5 inch full HD AMOLED display. The screen has a resolution of 1320*1080 pixels. The display is protected by 2.5D corning Gorilla Glass 5. So the glass will be slightly curved at the edges. The quality of the display will be good as it has a AMOLED display. The screen should be easily visible in direct sunlight. The colors will be look good on the phone. Overall Micromax Dual 5 is equipped with a good display.
 
Processor
 
 
 
Micromax Dual 5 is powered by Qualcomm's Snapdragon 652 chipset. This chipset is really good one as it is equipped in many of the other mid range smartphones and they performed really well. This chipset is based on octa core processor with four cortex A-72 cores and four cortex A-53 cores. There will be no lags in day to day usage of the phone. The phone should perform all the tasks without any issues.
For good graphics this device is powered by Adreno 510 GPU which can handle all graphic intensive works without any issues. This device should play all the heavy games like Asphalt 8, Nova 3, Modern Combat 5 and many more without any issues. There should be no lags and frame drops in the game play. So overall the device is equipped with a good processor.
 
Camera
 
 
 
The device is having very interesting rear camera. It has all the features what a camera centric smartphone should have. The device is having a dual rear camera setup. Both the sensors are of 13MP. Among these two sensors one is a color sensor and the other being a monochrome sensor. These two sensors combine their two images into one and produce a better image after combination. The rear camera has an aperture size of f/1.8, which is good.  So the rear camera will allow more light to enter the sensor for better detailing. Also the camera has phase detection autofocus and dual LED flash. The camera app is really simple. The camera is also having a pro mode in which we can adjust many things according to our choice like exposure, ISO levels, contrast and many more things of the camera which gives a full camera like feeling. The rear camera can record videos upto 4K.  The device is equipped with a 13MP secondary camera with flash. This camera can record videos upto full HD.
 
Operating system
 
 
 
Micromax Dual 5 is powered by the Micromax's self customized operating system which is based on Android v6.0.1. The user interface of the phone is good. There are no lags whatsoever in normal usage of the device. It also handles all the tasks without any issues. We expect that the device might come with android nougat but it is coming with marshmallow. But the device will get Android Nougat update hopefully.
 
Battery life
 
The device is equipped with 3200 mah non removable battery. So the battery life of the device should be good. It should easily last for a single day. But these days we usually see devices with massive batteries something around 4000 mah. This battery can easily last for 1.5 day. But even a full day's battery life is decent. This  phone also supports fast charging 3.0 which charges phone really fast.
 
Security
 
 
 
The company is saying that the phone is really secured. The phone is equipped with a special chip which controls all this security stuff. It secures all our fingerprints and passwords. It comes with a special operating system which unlocks when we touch a specific fingerprint. We can add a specific fingerprint to this mode. If we unlock the phone with that particular fingerprint the phone automatically opens that particular operating system. In this OS we can add our private things like photos, videos and apps. We can add our payment apps to this system for secure payments. And apps in this OS will not be shown in the normal OS. So this is really good for security.
 
Also this device has a special key on left side. We can customize this key according to our choice. We can use it for many purposes like cleaning apps, taking photo, switching on torch and many more.
 
Final verdict
 
 
 
Micromax Dual 5 is priced at 25000 INR. At this price it competes with those of Oneplus 3, Leeco Le Max 2, Xiaomi Mi 5 and Honor 8. Among them Honor 8 is a camera centric smartphone. Micromax Dual 5 is a good device but a overpriced smartphone. We have much better choices at this price point like Oneplus 3 and Leeco Le max 2 which are powered by Snapdragon 820 and are really famous for their great performance. No doubt the phone is having a good display, fast processor and a good camera but spending 25000 INR for a Micromax device with these specs is little impractical. The phone is also having some great features like security chip and special key on left side. Now the whole thing depends on the camera performance of Micromax dual 5. The camera performance of the device should have to be really good to be considered in this price range otherwise the phone won't be a good buy at this price. But it is good to see that the Micromax is doing something to get it's prestige back in the market.

Rdmi 4a

Redmi 4a

 
Xiaomi is very well known company for affordable smartphones, it has given many smartphones in budget segment like Redmi 1, Redmi 2, Redmi 3s and now it's turn for Redmi 4a. Xiaomi launched Redmi 4a this week in India in budget segment. Redmi 4a is the most affordable among above listed phones. Xiaomi launched this phone at 6000 INR in India. The phone is available on amazon through flash sale. So let's see some of the specs of the phone and see whether this phone is good or bad according to the price.
 
Specifications

 
 
Size: 5.0 inch
Display: IPS LCD type HD display
Protection: not specified
Resolution: 720 x 1280 pixels
Processor: Qualcomm's Snapdragon 425 chipset based on quad core processor with each cortex A-53 chipset cloaked at 1.4 GHz

Camera:
Primary: 13 MP with f/2.2 aperture, autofocus, LED flash
Video: upto 1080p @ 30fps
Secondary: 5 MP with f/2.2 aperture
3.5 mm jack:  Yes
 
Design

 
 
Redmi Note 4a is a 5 inch device. The device has a plastic body. So the phone's build quality us not that much great as nowadays we usually see phones with metallic build. But the phone is really compact as it has a 5 inch size. The phone is also really light at just 130 grams weight. The device is 8.5 mm thick. On top the phone has 3.5 mm jack, secondary noise cancellation and IR blaster. On right it has volume rockers and power button. On bottom it has USB port and microphone. On left side it has SIM tray. The phone also has chamfered edges which looks really good. This phone is one of the rarest phones to hold IR blaster in the device. So overall the device looks really good and feels premium in hands.
 
Display

 
 
Redmi 4a has a HD IPS LCD display. It has a resolution of 720p. The size of display is 5.0 inch. The resolution of the display is low as nowadays we normally see full HD display but we can't complain at this price point. The display should be good in indoors but in outdoors I can't say anything. Users can face problems while seeing display in direct sunlight.
 
Processor

 
 
The phone is powered by Qualcomm's Snapdragon 425 chipset which is based on an quad core processor with each cortex A-53 core cloaked at 1.4 GHz. The processor should be good in normal day to day usage. There should be no lags in normal usage. It should play casual games without any issues. But while playing heavy games the phone can face problems as it is having very basic processor.
 
User interface

 
 
Redmi 4a is powered by MIUI 8 which is based on android marshmallow v6.0.1. The user interface of the device will be same as those of other xiaomi devices. The user interface is good as it has many features. There will be some of bloatware pre installed with the device. The UI has lot of themes also, so this is also good. So overall the experience with MIUI should be good without any lags in normal day to day usage.
 
Battery
 
Redmi 4a is powered by the non removable 3120 mah battery. The battery life of the device should be good. It should easily last for a single day on a typical day's usage for a moderate user on a single charge. But for heavy users there may be some problem. The device also doesn't support any quick charging so it may take some time to charge phone. But we can't expect more at this price.
 
Final verdict

 
Redmi 4a is a really good device at the price. There is no such device at this price. It has all the features which a good smartphone should have. It has good processor, good design, good display, compact size at just 6000 INR. So this is really good. It has IR blaster which is not available in some of very premium devices. So expecting something more than this is not justifiable. But the device is available on Amazon through flash sale, so it is really difficult to grab the device. But the device is really value for money at this price point. We can't expect more at this price. But there are some features missing in the device like fingerprint sensor. At 7000 INR we can also go for Redmi 3s if we want slightly better processor, rear camera and battery life,while all other features are more or less similar to this device. But this device is also not a bad one, if you have a strictly tight budget you can also go for this device. My personal choice goes with Redmi 3s because spending 1k more is not a very big thing.

Lenovo Where are Updates?

Lenovo where are Updates?

 
 
Lenovo is a Chinese company which is very renowned for it's PC market. From last three four years it is also launching many  android smartphones in the market. The company uses it's self customized user interface based on android in it's smartphones. So the smartphone should get regular software updates from time to time. The company should also provide security updates every month. The company make many promises about the software updates at the launch of the smartphones. For 2-3 months only after the launch the company provide software updates but after that the company provide updates very rarely. So I have a big question from Lenovo that Please provide updates for it's smartphones and if it can't provide these updates, please simply don't make false promises and stop saying that we keep our phones updated.
 

So based on this, Ash from C4etech has posted a video on it's YouTube channel. I am linking this video here so that you can have better understanding about what I would like to convey.

These smartphones have many functions. But due to human nature everyone want additional features in their smartphones. Keeping in mind this, smartphone companies launch successor to their previous smartphone models with some improvements.

 
 
Various smartphone announcement events happen every year across the globe. One of them is Mobile World Congress (MWC) which is the main mobile event and occurs every year. This event starts every year in the late February and ends in early march. In this event many smartphone companies unveiled their smartphones. This year MWC held from 27th Feb to 2nd March at Barcelona. And many companies unveiled their smartphones there this year. The smartphones companies which unveiled their smartphones at MWC are Nokia, BlackBerry, Huawei, LG, Sony, Motorola, Nubia, ZTE and many more.

But due to the incident of Galaxy Note 7 last year it wants to give some more time on it's new flagship that is Samsung Galaxy S8. Without wasting further time lets see some of the specs of  the smartphones unveiled by various companies at MWC 2017.

BlackBerry


 
Few years back BlackBerry was one of the top smartphone maker. Their smartphones got very much famous due to it's unique design and special keyboard. But later on it's market got down due to launch of various large sized android phones which are full touch screen. At the end BlackBerry has no choice instead of selling their smartphone business to TCL communication  and focus on software instead.

 

The new smartphone we see today is the last smartphone from Blackberry that's why it has that distinctive keyboard. This new phone is known as BlackBerry KeyOne. It has 4.5 inch display which has 1080 x 1620 resolution. This screen is IPS LCD type screen. The device has aluminum frame and textured back. The device is powered by Qualcomm's Snapdragon 625 chipset with Adreno 506 GPU. The phone comes with 32 GB of internal storage and 3GB of RAM.

The keyboard used on this is backlit. It reminds us of the old keyboards which were used in earlier blackberry smartphones. But the keyboard used is highly advanced, it immediately responds as soon as we touch the key. The OS used here is Android 7.1 which is really surprising. Also there is some blackberry stuff in the OS.
And lastly the phone will be available from April and will be priced under $600.

Nokia

 
 
Nokia was one of the most prominent brand name in the smartphone history. It was well known for it's feature phones all around the globe. The company was leading the phone market all around the globe. But with the transformation of phone market to smartphones the Nokia's hold on the smartphone  market weakens. The launch of various android powered smartphones reduced the sales of Nokia phones. In competition to these android phones Nokia introduced it's Lumina series which are powered by windows software. But it didn't work too well and at last Nokia has to sell it's smartphone business to Microsoft with a contract. Now that contract has ended so company is trying to make a comeback in the market. So in 2017 Q1 Nokia is announcing it's Android powered smartphones.


 
 Nokia has already launched Nokia 6 last month in China and it didn't mention anything about the global availability. And now at MWC 2017, Nokia announced two more android devices that are Nokia 3 and Nokia 5. And it also relaunched one of it's previous feature phones that is Nokia 3310.

 
 
Nokia 5: Nokia 5 is 5.2 inch device. The device has a IPS LCD type display and has HD resolution. The display is protected by corning gorilla glass. The device is powered by Qualcomm's Snapdragon 430 chipset which is based on a octa core processor with eight cortex A-53 cores cloaked at 1.4 GHz. There is also Adreno 505 GPU. The device has a aluminum unibody design. So it looks premium in hands. It has a 13 MP rear camera with f/2.0 aperture with phase detection autofocus and dual tone LED flash. The secondary camera is of 8 MP with f/2.0 aperture. The device comes with 16 GB of internal storage and 2 GB of RAM. The phone is powered by Android Nougat 7.1 and company is promising to update the software regularly. The device comes with 3000 mah non removable battery. The device has front facing fingerprint sensor and has all other basic sensors.

 
 
Nokia 3: Nokia 3 is another device which company unveiled alongside Nokia 5. Nokia 3 is having the design like higher end versions of Lumina series, the phone has an aluminum frame. On front it has 5 inch HD display. The display is IPS LCD type and is protected by the Gorilla glass. It has 8 MP rear camera and 8 MP secondary camera while all other camera's features are same as Nokia 5. The device is powered by a quad core Mediatek chipset and has Mali-T720MP2 GPU. The phone also comes with 2GB of RAM and 16 GB of onboard storage. It also comes with Android 7.1 out of the box.

 
 
Nokia 3310: Nokia 3310 is very basic type of feature phone. There is no point of relaunching this device at this time where all use smartphones. The device is only for basic work like calling and playing very basic older games such as Snake, Paris, space impact. The device doesn't even have the Bluetooth in the device. It has a 900 mah removable battery. This type of phone is totally useless at this point of time.
 
Sony

 
 
Now it's time to get a look at Sony's flagship phones. This year Sony unveiled two flagship smartphones at MWC 2017 that are Sony Xperia XZ Premium and Sony Xperia XZs. Also it unveiled two other mid range smartphones at MWC 2017 that are Sony Xperia XA1and XA1 Ultra. So let's have a look at them.

The Phone has a full glass design which runs all around the phone and is protected by Gorilla Glass 5. The device is a little bit heavy with 195 grams weight and 7.9 mm thick. It is the second phone from the Sony which has a 4K display. The display is IPS LCD type and has a resolution of 3840 x 2160 pixels. The phone is powered by the Qualcomm's Snapdragon 835 chipset which is the latest chipset from Snapdragon.
