Samsung Galaxy A80 Launched

Samsung launched 'A' series flagship - Galaxy A80 with rotating camera

Samsung supressed by the chinese tech giants dominating in India because of the value for money phones and steep competition amongst them. Also recently Dj Koh, global president of IT and mobile communications division of the company said in a statement "If we take a nap, we will die. I don't want to die," with a smile on his face.

Samsung Galaxy A80 

Now talking about the smartphone, Samsung Galaxy A80 was launched on Wednesday at an event in Thailand. Galaxy A80 is currently the flagship phone amongst Galaxy A series.

Specifications -

Design and Display - 

Samsung Galaxy A80 features a 6.7-inch FullHD+ (1080x2400 pixels) Super AMOLED infinity display with an aspect ratio of 20:9 and no notch. The phone has a glass sandwich design with aluminum on the sides of the phones.

Camera and Hardware - 

The smartphone is powered by Qualcomm's Snapdragon 730G octa-core processor with (Kyro 470 cores) two cores clocked at 2.2Ghz and six cores clocked at 1.7Ghz And paired with 8GB of RAM. For graphics-intensive duties, it comes with Adreno 618 GPU.

Now, the main highlight of this phone is the camera and this smartphone features a triple rotating camera setup on the top and hence no notch. The phone comes with a primary 48-megapixel camera with f/2.0 aperture. The secondary camera is an 8-megapixel ultrawide lens with a field of view of 123 degrees and f/2.2 aperture. The third camera is a 3d depth-sensing camera. For selfies, all three cameras on the phone automatically pop-up and rotate to the front. Since the camera is rotating, it makes the rear camera rotatable for selfies with high-resolution rear camera usable for selfies. And the rotating camera also enables the phone to have a notchless display.

Software, battery, and features - 

On the software side, the phone comes with Android 9 pie out of the box on top of Samsung experience 10.0 user interface. The phones come with an inbuilt 128GB of onboard storage which isn't expandable via microSD. The smartphone comes with a 3,700 mAh battery and supports 25w fast charging. And comes with all the basic connectivity options.

It comes with features like Dolby Atmos for improved sound output with headphones or Bluetooth speakers. It also comes with super steady video mode and an intelligent performance enhancer that uses AI for performance optimizations. 

That's all for Galaxy A80 and it has been priced at 649 EUR ( Roughly 730 USD )

 Considering the price at which it has been launched this phone seems no value for money but Samsung always prices its phone better for Asian markets like India. But those rotating cameras do not seem to be as reliable as on a normal smartphone and not even as much durable when compared to normal smartphone cameras.

Periscope camera lens - Probably the next big trend in smartphones

Periscope zoom camera lens in smartphones

are the next big thing 

Back in mobile world congress 2019, when Oppo showcased the prototype of the periscope camera lens in their smartphone that can go up to 10× lossless zoom. And it was one of the most innovative technologies in mobile world congress, that a periscope camera lens has been used in a smartphone to provide features like digital cameras in a smartphone.

Periscope camera lens - How it works?

 Now talking about the method of the technique used in there for a periscope camera lens in a smartphone is almost as similar to a normal periscope where mirrors are fitted into each end of the tube at the angle of exactly 45 degrees. light is reflected from the top mirror to bottom mirror at an angle of 45 degrees because the light is always reflected by a mirror at the same angle that it hits the mirror.

 Now in smartphones, the same thing happens where external lens captures an image and reflects it inside on a mirror, and another lens transmits the image to the camera's sensor. So, a periscope lens would enable camera in the smartphone to create a sophisticated optical zoom system.

Is it really 10x optical zoom? No!

The Oppo phone showcased at the Mobile World Congress supported up to 10x lossless zoom but technically, what company did was that they placed the main sensor as a 'more' ultra wide lens and the focal length of the camera used in the prototype phone was 16mm instead of a regular lens used on the smartphone so that phone can go from 16-160mm. But when Oppo showcased its 5x optical zoom prototype in Mobile World Congress 2017 it used the regular lens on their smartphone at that time. So, Oppo played it smart. Now, the phone showcased by Oppo at Mobile World Congress 2019 is technically still the 5x optical zoom.

Now talking about the periscope lens used in smartphone cameras, it is definitely the future of smartphone cameras and the upcoming smartphones with periscope lens would be much more sophisticated and powerful. We can assume smartphone cameras to be as much feature packed as digital cameras if not replacing them.
