What process does a mobile experience before it reaches our hands?


We live in the technological age at a time when we like to relate to others through the internet and share everything we do. For this reason it is rare to see someone today who still does not have a smartphone with which to operate in virtually any everyday environment. It has become an object of our day to day, accepting as one of the family, becoming for many something almost essential to survive. But regardless of how we use it, few are those who notice in the creative process, testing and production that is behind all this technology.

Normally, when we decide to buy any phone, we look at its aesthetics, what features it offers, if it has enough memory for our photos and documents, if the camera will be the most suitable, if it offers a good sound to listen to our favorite music, and a long etcetera. And not only that, we are very demanding when it comes to quality.

But what’s behind that chosen smartphone? How did it get to the market? Who has decided that he is fit to face the public?

Let’s see what’s going on behind the scenes.


Like any team project in which we can start, we start from sketches, design and ideas that we need to translate them on paper.

Therefore, we can say that the beginning is the most intense phase, since all the ideas that we have have to be shaped in a logical way. This is where the first 3D prototypes appear where everything is measured and calculated with great precision, such as the size, weight and density of the screen. It’s about everything that has to do with design, what you’re going to see, but nothing that has to do with functionality.

To see a practical case of what we said, We can look at the Aquaris phone from BC. For example, for this model, 2 types of validations are performed. The first, called Engineering Validation Test, and the second called Design Validation Test, during which the terminal can be modified up to 60% and where the welds and bolting of the prototypes and their reliability are checked.

Next steps

After these design and prototyping tests, comes the fundamental and at the same time critical part. We’re talking about electronics.

There are 3 fundamental components, which are: the part that controls the keyboard and the reception of the signal, the battery and the screen. All this hardware needs specific software, and in many cases it is proprietary software of the brand / company, where the programmers assigned to it develop the design of the interface and the basic / advanced operations of the phone. Some of these could be Calendar, Clock, and message writing.

For example, following the example we mentioned with the Aquaris phone from BQ, a Test Test called PVT (product validation test) is performed. And what exactly does it consist of? 1000 units are generated exactly the same and on these are carried out the performance tests on the battery and the processor fundamentally, since in short, they are the heart and engine of our terminals.

After passing this point, it is when the final phase begins, in which each part of the phone is assembled and the rest of the components are added, such as the camera, the antenna, the microphone and the speaker. Tests are then carried out to verify the functionality of the buttons and the power of the phone. How would this be in the case of the Aquaris? The CTS Verifier is carried out, which is nothing more than the external testing of the terminal which is carried out together with more than 230,000 performance and performance tests divided into different modules (camera, sensors, connectivity, codecs …).

And once all these tests are passed, it is when the necessary documentation that will accompany the smartphone is written and it is after that moment that the definitive model to present in the stores is born.


As we have seen, there are many tests, tests and certificates that are carried out until the final terminal reaches our hands.

We are talking about a process that takes between five and seven months of constant work and many adjustments. Therefore, let’s not underestimate our smartphones and think about everything that has gone through to reach each of us.

If you want to know more about what quality tests are carried out, for example, with cameras and audio, you can continue reading the article by xataka that gives a very good explanation about all the processing of the Aquaris phone from BC.
