HDC S4 Spark: review

HDC S4 SparkWe have been very busy answering a lot of emails and trying to figure out a lot of aspects of the new HDC S4 Spark so as we promised you, here you have a review of the latest chinese smartphone that supports all the gesture control capabilities!

Just before we forget, we would like to ask for patience to all those readers that we haven’t answered their emails yet, please be patient as we are still dealing with our overcrowded inbox, so please give us a 24-48 hour time period to reply. (at this time all emails have been replied!)

Said that, let’s talk about the HDC S4 Spark in broad terms, as you already know this is a 5.0 inch MTK6589 equipped chinese smartphone very similar to the HDC S4 Legend, that was one of the first chinese devices stuffed with the Air View and Gesture Control capabilities. Now, the HDC S4 Spark seems to push these capabilities way further and is offering (besides Air View & Gesture Control) what is known as Smart Stay.

Let’s check some of the most common features in this HDC S4 Spark, just to answer the most common question that has been mailed to us :

‘What’s the difference between S4 Spark and S4 Legend?

Just to put it simple, we have been told that you can ‘unlock’ some features behind Air View, Gesture Control and Smart Stay, but this seems to require knowledge around Android and expertise with Engineer mode codes and apps, so at the moment we are not going into this, we just want to throw some light on ‘The real difference between each other’ which is in fact, the Smart Stay feature, so let’s find out what is this all about.

Smart Stay:

With Smart Stay, the screen stays on as long as you are looking at it. Something similar happens with Smart Pause which is intended to pause a video if your eyes look away and on the other hand we could have Smart Scroll, but this is NOT supported.

Smart Scroll would allow you (if it were supported) to follow your facial motion and the tilt of your device to automatically scroll up or down a website.  So, plainly speaking Smart Stay in the HDC S4 Spark let’s you pause videos and (we are waiting for this to confirm) you are supposed to be able to turn off the screen if you are not looking at it straight.

Gesture Control and Air View:

We are just waiting for some precise information about what can you do with this phone with the Air View capabilities, hopefully we are getting some feedback throughout this week.

On the other hand, it seems that with the HDC S4 Legend there is no possibility of previewing emails, pictures, contacts, etc..we encourage our most experienced readers to submit us any kind of information or experience around the Air View thingy.  We are saying this because as far as we are concerned there is neither the option of hovering over nor the possibility that the device detects our finger approaching the outer most of the screen.


(*)If any blogger/reader/techie/geek/developer/engineer/IT guru out there has any/more information about the Air View capabilities with the S4 Spark send us an email at info@multicorechina.com and we’ll update the post gladly, as we think it is better to share  your insight and our knowledge with the Multicorechina.com community and with all the chinese smartphones fans around the globe.

How it works?

HDC S4 Spark

Of course, to perform all these movements that allow you to dictate your own guidelines to the smartphone, we need a sensor located just close to the front camera and light sensor, all these sensors gather information that combines with some code, and then it enables you to make weird gestures that control your device.

Confirmed gestures:

Air Browse: Move to the next or previous screen by moving your hand left or right above the sensor, this is cool, definitely.

Air Jump: Scroll through web pages and body of emails by moving your hand up or down above the sensor.HDC S4 Spark

Air Call: Accept incoming calls by moving your hand over the sensor. By default, the speakerphone will be activated when the call is answered.

HDC S4 Spark

Mute calls: When activated, turning the device over will mute incoming calls and media playback.

Confirmation pending:

The gestures below need to be confirmed but from our point of view, they should work as they are merely ‘variations’ of primary movements/gestures. If you have tried to do this with an S4 Legend or S4 Spark please drop us a comment or mail us.

Mute/pause: Mute or pause media playback or the FM radio by covering the screen with your hand. According to our Android experts, this gesture should work on the HDC S4 Spark.

Quick glance: When your device is on a flat surface with the display facing upwards and the screen is turned off, move your hands above the sensor to display status and notifications information.

HDC S4 Spark

So, if this HDC S4 Spark works as smoothly as the HDC S4 Legend does, we definitely recommend its purchase as it comes with an extra feature -Smart Stay- that we are pretty sure can be ‘tweaked’ in the near future, allowing extra gestures – but we need to confirm this last point yet-

You can buy the HDC S4 Spark HERE.

    Hi MCC,
    Thanks for your reply.. can you spot any differences between clone and original ?
    NFC and Sbeam works well ?
    Because there are too many series of clone.. It is not easy only to spot from hardware since the hardware is similar now.. Perhaps you could make a post to differentiate the original and clone one..

    Thank you
