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

We live in the technological age at a time when we like to interact with 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 get along in practically any everyday field. It has become an object of our day to day, accepting as one more of the family, becoming for many something almost essential to survive. But regardless of the use we give it, few are those who notice the creative, testing and production process 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 asking for quality.

But what is behind that chosen smartphone? How did you get to the market? Who has decided that he is fit to be in front of the public?

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

Start

Like any project we can start, we start from sketches, design and ideas that we need to put on paper.

Therefore, the beginning can be said to be the most intense phase, since all the ideas you have have to be expressed logically. It is there that the first 3D prototypes appear where everything is measured and calculated with great precision, such as, for example, the size, weight and density of the screen. It’s about everything that has to do with design, what is going to be seen, but nothing that has to do with functionality.

To see a practical case of what we are talking about, we can look at the Aquaris phone from BQ. For example, for this model, 2 types of validations are carried out. 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 welding and bolting of the prototypes and their reliability are reviewed.

Next steps

After these design and prototyping tests, the fundamental and at the same time critical part comes. We are talking about what has to do with 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 for it develop the interface design and the basic / advanced operations of the phone. Some of these could be the calendar, the clock and the writing of messages.

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 exactly the same units are generated and the performance tests on the battery and the processor are mainly carried out on these, since in short, they are the heart and the engine of our terminals.

After passing this point, 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, antenna, microphone and speaker. Then the tests are made 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 operation and performance tests divided into different modules (camera, sensors, connectivity, codecs …).

And once all these tests have been passed, it is when the necessary documentation that will accompany the smartphone is drawn up and it is after that moment that the definitive model is given birth to be presented in stores.

Finding

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 they have had to go 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 xataka article that gives a very good explanation about all the processing of the BQ Aquaris phone.
