SAMSUNG GALAXY S7 review


The long awaited Samsung Galaxy S7 and S7 edge was launched on Sunday, 21 February 2016. It was exactly all we expected it to be. But iPhone 7 is a long way from being launched. The major features of Samsung Galaxy S7 are:


  • Display: 5.1in Super AMOLED 2560x1440 pixels (QHD), 577ppi (Galaxy S7 edge: 5.5in, 534ppi)
  • Storage: 32GB onboard (larger capacity models MAY be available), microSD slot
  • CPU and RAM: Qualcomm Snapdragon 820/Samsung Exynos 8890 processor (region dependent), 4GB RAM Front Camera: 5MP
  • Rear Camera: 12.2MP, f/1.7 aperture, 1.4um pixels, dual­pixel 100% phase detection sensor  IP68 water and dust proofing (1.5m submersion up to 30 minutes)
  • Battery: 3,000mAh (Galaxy S7 edge: 3,600mAh) NON­removable


It looks sleeker than the S6, a better camera than S4. Both the front and the back are covered with Gorilla Glass. It has two volumes buttons sitting on one side with a clock switch on the other.

It’s a big screen, many people dislike big screens, they say it’s cumbersome, can easily drop and can’t fit into our pockets but I personally love the big screens. It has a cool experience when browsing or watching videos or playing games.

Like I said earlier on, Samsung launched two phones S7 and S7edge, the standard S7 (5.1­inch , $650-$695) and S7 edge (5.5­inch, $750-$795) both depends on the carrier with a curved display technology.

Here is the thing about smart phones, they are a lot better when the have big screens, everything we do is much better with a larger display, messaging, playing games watching videos.

Both S7 and S7 edge displays look gorgeous, with vibrant hues and punchy colors. Of course, there's also the curved design to Samsung Galaxy S7 Edge but S7 is not much different from S6 with its 5 inch display Squad HD and Super AMOLED ( More durable, no more plastic, just glass and aluminum (metal), both same shape and design) A little bit thicker than S6 and they both feel extremely nice in the hand. 

Samsung designed both S7 models to be both dust and water resistant. They can stay up to 30 minutes fully immersed in water; the important thing here is that you don’t have to worry about being a little clumsy like spilling your coffee when your phone is on your desk, keeping it by the sink when you’re doing dishes, calling an Uber in a rainstorm, or, worse, dropping it in the toilet when you’re a few sheets to the wind. 


Samsung isn’t the first phone company to make a water resistant phone, nor are the S7s Samsung’s first water resistant models, but it’s something that all phones, especially high­end ones, should have on their spec lists.

My only real complaint is the glass on both phones is like a rare earth magnet for fingerprints. It also makes them slippery, especially in cold weather when my skin is dry.
Samsung has made some big changes to the Galaxy S7 camera. 

For one thing, the megapixel rating has actually shrunk to 12MP, but this is a deliberate act as Samsung is instead focusing on other areas of the hardware to improve image quality. Things like a wider f/1.7 aperture, a larger 1.4um pixel size and the world's first dual­pixel sensor with 100% phase detection auto-focus. 

It has a 32GB on board Storage capacity which is higher than most phones. Larger capacity models may be available but unlike any other phone I have seen, The new Samsung 7 has a slot for microSD. The amazing thing is that if you are the type of person who needs more than 32GB storage you can now insert a microSD card up of to 200GB. No need for Bluetooth or other wireless transfers that usually takes time  to configure setup or might have compatibility issues with other phone model.


The Samsung Galaxy S7 provides a more compact, sleek and refined all-around experience. If you have about $700 to spare, you can grab one of these gadgets and my guess is you won’t be disappointed because it’s an enthralling piece of metal.

Samsung Galaxy S6 review



Samsung has launched two phones, Samsung Galaxy S6 And S6 Edge at MWC2015.S6 stunning metal bezel that cascades into sophisticated glass (it has a metal chassis, and glass covering the front and back) with dual-edge screens. Both the S6 and S6 Edge comes in charcoal, White and Gold.The S6 Edge is slim, sleek, elegant, the S6 gets a surfy blue and has a curved edge. 

The S6 is lighter than its predecessor S5 and feels more balanced and solid than the S6 Edge.S6 has the power button located at the right side of the phone and the volume controls to the left side. The top has the menu button and microphone. The bottom edge has the charging point, power boosted speaker.

The downside to this phone is that there is no removable back panel meaning you cant change the battery or memory card. You cant upgrade from say 32G to 64G. Also the battery capacity hasnt changed that much (its even now lower), you have 2600mAh for the S6 Edge and 2500mAh for S6 and 2800mAh for its predecessor Samsung S5. It can give your 2 hours of HD video playback with just 10 minutes of charging.

One amazing feature is the wirless charging and also a normal chager too. The front facing camera is 5MP while the back camera is 16MP with 0.7 seconds activation for faster response and auto real-time HDR. 


It has a beautiful 5.1" Quad HD Super AMOLED display with a 2560 x 1440 pixel QHD resolution. And for a hint on the price,


Samsung Galaxy S6 32 GB: €749 (around £560, $855, AU$1100)
Samsung Galaxy S6 64 GB: €849 (around £635, $970, AU$1240)
Samsung Galaxy S6 128 GB: €949 (around £710, $1085, AU$1390)

A look at the specification:

Screen: 5.1in, QHD, 1440x2560, 572ppi, Super AMOLED
Processor: 64-bit Exynos, 14nm process 
RAM: 3GB LPDDR4 
Storage: 32/64/128GB using UFS 2.0 tech – no microSD
Camera: 16MP, f1.9, Smart OIS, HDR (rear); 5MP, f1.9, HDR (front) 
Battery: 2550mAh 
Dimensions: 143.4x70.5x6.8mm, 138g 
Colors: White, charcoal, gold, blue


Just to end by saying that Samsung is still sticking with Android as its operation system. All phones, S6, S6 Edge and S5 all have the Android  operating system.

A Transforming Robot



Many of you might have watched the movie "Transformers", the franchise is now in its fourth installment, Transformers Four: Age of Extinction, starring Mark Wahlberg and Stanley Tucci. Until now, the transformer has only been a fictitious story, A team of hobbyists from Japan built a transformer (robot) it can walk and when in sports car state, drive around autonomously. They named it the "J-deite Quarter" It is actually four feet tall.

The team which comprises of Kenji Ishida and Wataru Yoshizaki of Brave Robotics and Asratec started working on the project since 2012 and they hope to build a bigger transformer that is eight feet tall.

Here is a specifications for more detailed information about "J-deite Quarter ":

Height in robot mode/length in vehicle mode: 1.3 m,
weight: 35 kg, maximum battery power: 3 kw,
operating time: 1 hour, number of seats: 2,
controlled by V-Sido OS.
Power source: servo motor manufactured byFutaba Corp.[Robot Mode SPEC]
Maximum walking speed: 1 km/h, gripping weight: 0.1 kg.[Vehicle Mode SPEC]
Maximum traveling speed: 10km/h, minimum road clearance: 40 mm.

I personally think that this Transformer will be more entertaining than be able to solve a problem like robots do. I also commend this great job. Keep up the good work!

IPhone 6 Review


The new iPhone 6 is much bigger than all other iPhones made in time past, much more comfortable to hold with improved camera. It was launched during a special event organized by Apple on the 9th of September 2014. 

Three devices where unveiled that day, the iPhone 6, iPhone 6 Plus and the iWatch. The Phone 6 has a 4.7in display while the iPhone 6 Plus has a 5.5in screen display. 

It is hoped that both models will help Apple reach more clients that were not using iPhone 5 or older. The question that goes unanswered is "What about those who prefer the 4in screen phones of the previous models of iPhone (iPhone 4 and iPhone 5)?" 

iPhone 6 has different storage capacities, it has the 16GB, 64GB and 128GB. There is no 32GB. I will recommend that you go for the 64GB or 128GB , because experience has shown that unlike other phones that the memory can upgraded, iPhones including iPhone 6 can not be upgraded. So when you have the need to have a larger capacity, you now discover that you are stuck with 16GB. Just like with every other phones, the higher the capacity, the faster the processor of your phone but this solely depends on the amount of video, apps, photos, music stored in it. Talking about processor, the iPhone has a 64-bit A8 processor, which is much more powerful than the A7 processor of its predecessors. The processor has a speed of 1.27GHz which is lower than Samsung's Galaxy S5 which has a speed of 2.5GHz. Both iPhone 6 and iPhone 6 Plus have the same RAM size of 1GB just like its predecessors.  



Apple has modified the shape of its new device, it is 6.9mm thick (that’s about eight stacked credit cards), weighs 4.55 ounces with rounded edges. This makes it comfortable to hold. It has a big screen with a resolution of 1,334 x 750 and 326 ppi density also makes watching videos, playing games and viewing images much more exciting.

If you are conversant with the iPhone 5s, you will notice that it has a round volume button, the new iPhone comes  with long metal ovals and the sleep/wake button has been moved to the right side of the phone. 

One draw back on the iPhone 6 is that the camera lens protrudes slightly so when the phone is laid flat, it does not sit evenly. There might be a technical reason behind that decision, or perhaps Apple might change this with future models. The good thing is that the camera is 8 MP that uses a new sensor called “Focus Pixels” with LED flash, auto-focus, advanced face detection and digital image stability.

The battery life is slightly better than its predecessors with a standard battery capacity of 1810 mAh which is not removable. With active usage the phone can make it through the day with about 20 to 30 percent of battery life still left.

The price of iPhone 6 varies, the 16 GB costs $650, the 64 GB costs around $750 while the 128 GB costs around $850. 

iPhone 6 also features a new  new super-fast WiFi chip and an improved Touch ID fingerprint sensor. The NFC of iPhone works with Apple Pay mobile payment service. 

Apple has no intentions of making its NFC open to third-parties and will only work with Apple Pay. Which means that developers coming up with new apps can't use this feature.
