With the Galaxy A9, Samsung ups the ante on photographic options – a likely winning bet

SAMSUNG Galaxy A9 is a fast smartphone that comes with a four-camera system for the rear camera for those who love taking photos.

High-end phones of other brands and models have at most a three-camera system for the rear camera, but Samsung claims to be the first to introduce a four-camera system.

The four rear cameras are an ultra-wide angle camera with eight-megapixel resolution and 120-degree lens with f/2.4 aperture; a telephoto camera with 10MP resolution and 2x optical zoom lens; a main 24MP camera with f/1.7 lens; and a depth camera with 5MP resolution and f/2.2 lens.

The depth camera provides data for creating beautiful bokeh – blurred background – effects like beautiful portraits captured by a digital SLR camera.

During the test, I found the rear camera system could capture beautiful and good-quality photos.

The ultra-wide is good for capturing scenery shots and group photos and the telephoto camera allows you to zoom in to your subject. The main 24MP camera has very bright and fast lens with f/1.7 aperture.

You can choose between the three cameras by tapping on three zoom icons in the viewfinder for the wide, normal and telephoto cameras.

There are several shooting modes to choose form, including Pro, Beauty, Auto, Live Focus and Scene Optimiser.

The Scene Optimiser uses AI to optimise colours and other settings to get best results for scenes recognised by the AI. The AI can recognise 19 scenes, including sunset, backlighting, scenery, portrait, foods and macro photography.

The Scene Optimiser mode also has a Flaw detection feature. With Flaw detection, if a photo is taken poorly, the device will notify you to take the photo again. For example, when someone blinks or appears blurry in photos, or if there are smudges on the lens, a notification will appear after you take the photo.

The Live Focus mode is use for capturing outstanding subjects with blurred background. In this mode, you will be given a slide bar for adjusting the level of blurred background.

You can also edit the background blur level of a photo taken with the Live Focus mode. And if there are background lights, you can change the shape of the background lights into hearts, stars or flowers when you are editing the photo.

The Galaxy A9 also comes with a 24MP front camera with f/2.0 aperture. The front camera captures beautiful selfie shots. And there is also an AR Emoji mode for creating a set of emoji icons that look like you.

The front camera comes with several selfie modes, including Selfie focus mode that focus on your face by blurring the background.

I found during the test that the Live Focus mode captured beautiful portraits with blurred background.

The A9 has good performance as it is powered by a Qualcomm Snapdragon 636 octa-core processor with four cores running at 2.2GHz and four others at 1.8GHz.

Enhancing the performance, the A9 is equipped with a hefty 6 gigabytes working memory or RAM and it comes with 128GB internal storage that can be expanded with a microSD card of by up to 512GB.

The Galaxy A9 runs on Android 8.0 and it has fast performance. Its touch screen and menus were responsive and apps ran fast and smoothly.

The Galaxy A9 also has fast Internet as it supports LTE Cat 9 4G connection. I tested it on TrueMove H’s LTE network and I found that it had very fast Internet connection.

Apps were downloaded very fast and my snapshots were backed up to my Google Photos cloud storage in no time. I used Ookla Speedtest app to measure the connection speed and I found that Galaxy A9 got the download speed of 102Mbps and upload speed of 38.4Mbps.

Galaxy A9 comes with 6.3-inch Full HD Super AMOLED display with 1080x2220-pixel resolution. The display is really beautiful for watching photos and HD movies. During the test, I enjoyed using A9 watching Full HD movies with TrueID TV and iflix apps.

The Galaxy A9 also features an Always On Display, which lets you view key information like the date, weather, time and incoming notifications in a flash on its wide screen.

Galaxy A9 comes with good security system to protect your data. You can use either Face Recognition technology to unlock the phone very fast. During the test, I found that the Face Recognition technology worked very efficiently to unlock the phone. I simply pressed the onscreen home button of the Always On screen and the front camera read and recognise my face and unlock the phone.

The Galaxy A9 also comes with fingerprint reader at the back for fast unlocking the phone with your finger.

The A9 comes with a large battery of 3,800mAh, which allowed me to survive a day after one charge. 

Samsung Galaxy A9 is available in Caviar Black, Lemonade Blue and Bubblegum Pink for Bt19,990.
