You probably know it, or not, but a smartphone has many internal parts to function. Differences exist according to the models and brands but the structure remains the same. We explain the components that you will find and their use. Interesting to understand the possible breakdowns🙂
It is the most famous component! Because it is the component most subject to breakage, since it takes up the entire front face!
It is necessary to distinguish between the touch screen glass and the display panel . But on the vast majority of the most recent models, the screen forms a single inseparable block . Whether it is a touch or display problem, it is therefore necessary to replace the complete screen unit. Where it was possible to change one or the other on some models (like the Galaxy S3 or S4 in their time).
The touch functionality is now often integrated into the display panel and not the glass. To limit the thickness of the screen and the multiplication of layers. It also allows better tactile responsiveness. You do not notice it because it will be, anyway, necessary to change the inseparable screen unit in the event of a problem.
On some smartphone screens, there are screens pre-assembled with the chassis as well as components already present such as the front camera or the internal speaker. This is possible on iPhone in particular. And even some official Huawei screens that even include the battery. This facilitates installation and exchange but requires the complete change for a touch problem, display, or even broken screen.
The backlight of the screen is located on the LCD panel or is directly integrated into the AMOLED technology you can get all mobile spare parts from Cellular Screens. It may happen that the display of the smartphone remains black but a light is emitted under the screen. It is the backlight that works but not the display panel.
Possible failures: display problem, touch fault, broken screen.
Second most famous element: the smartphone battery! It is the element of wear par excellence. The battery inevitably deteriorates over time. The new Li-Ion batteries no longer suffer from the memory effect as was the case on the first phones. That is, you can charge it anytime, it will know where it is. Early Nimh batteries mistakenly thought that it was fully charged when you unplug them.
There are methods to best preserve its autonomy but it is undeniable, after 2 years, the autonomy is less good. No problem, it’s easy to change your battery with SOSav !
Possible breakdowns: low autonomy, charging problem, swollen / overheating battery.
smartphone back cover
The back of a smartphone helps protect internal components from shocks and drops. It also prevents dust and other residues from entering. A few years ago, the back cover was often clipped in and easy to remove. It is now a past time. It is often a rear window (glass or plastic) which must be removed by heating it.
Possible breakdowns: broken shell, cracked rear window, rear face that no longer holds in place, etc.
smartphone charging connector
It is the lightning, micro USB or USB-C port that equips your smartphone. If your phone no longer detects the charge or is no longer recognized by your computer, it is the fault! Indeed, it is used to synchronize your data or to make a backup on your PC. Often, it even includes the main microphone which is used to pick up your voice during calls. It is not rare either, that the GSM antenna is integrated there too. A major piece.
Possible failures: charging problem, not recognized by the computer.
There are two speakers on a smartphone. The listening speaker (internal) located at the top. It delivers the sound of calls, that’s why it is at your ear level when you call.
And the main (external) speaker which is at the bottom of the phone. It relays all the other sounds emitted by your smartphone: ringtone, music, video, call in speakerphone mode, etc.
Possible breakdowns: no sound, sizzling sound, cutting sound, distant sound.
Again, there are two cameras on a phone. The front camera (front) which is used for your selfies! It is on the front side of your mobile.
And the rear camera (main) which is located on the back side. Usually it has better resolution. Moreover, the latest smartphone models are even equipped with double, triple or even quadruple sensor on the back with telephoto and wide angle.
Possible failures: blurred photo / video, black image, error message when opening the camera.
Tablecloths and buttons
Recent smartphones no longer have a home button with their borderless screens. But there are always the On / off, volume and sometimes even camera or fingerprint buttons . Buttons are generally pieces of plastic associated with a connecting sheet . The tablecloth is often a separate item and the problem usually lies with it. It is she who creates the click and pressure effect to trigger the button action.
Possible failures: torn tablecloth, broken button, button that no longer responds.
The internal chassis is literally the backbone of the smartphone. Indeed, it keeps the various smartphone components in the right place. Concretely, it makes the junction between the front face and the back face. If the frame is twisted, the screen and / or the back panel may be twisted too hard and crack.
Possible breakdowns: bent frame, broken frame.
On a telephone, there are, again, several microphones. The main microphone used for calls is often associated with the charging connector. But there are also at least one, if not two, secondary microphones. Often associated with another component as well, such as a camera or proximity sensor cable for example. The secondary microphones are used for recording videos, voice assistants, dictaphone, etc.
Possible failures: no recorded sound, interlocutors cannot hear you, the sound sizzles when you are filming, etc.
The vibrator is a mechanical part. It vibrates upon receipt of notification, according to the settings you have determined. If you notice that it no longer vibrates properly or too weakly, worn out or following a shock, you must replace it.
Possible failures: no vibration, low vibration, random vibration.
Proximity and brightness sensor
A small element that can quickly pose a problem in the event of failure. It is thanks to this sensor that your screen can adapt its brightness according to the environment . Brighter in direct sunlight to stay readable and darker in the dark to dazzle you less. It is also the one that detects the approach of the phone to your face for calls. Indeed, it automatically turns off the screen to avoid triggering apps with the friction of your cheek.
Possible failures: brightness that does not adapt automatically, screen that does not lock during calls, screen that remains black after a call.
