Smartphone spare parts: a handy glossary!

You probably know it, or not, but a smartphone is made up of many internal parts to function. There are differences between models and brands, but the structure remains the same. We explain the components you will find and their usefulness. Interesting to understand the possible failures🙂


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 make the distinction between the touch screen and the display panel . But on the vast majority of the most recent models, the screen forms the same inseparable block . Whether it’s a touch or display problem, you have to replace the complete screen unit get mobile phone best parts from Maya Mellular Parts. Where it was possible to change one or the other on certain models (like the Galaxy S3 or S4 in their time).

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. This also allows for better tactile responsiveness. You do not notice it because it will, in any case, be 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 the installation and the exchange but requires the complete change for a touch problem, display, or even a broken screen.

The backlight of the screen is on the LCD panel or is directly integrated on the AMOLED technology. It may happen that the display of the smartphone remains black but that a light is emitted under the panel. It’s the backlight that works but not the display panel.

Possible failures: display problem, touch defect, broken screen.

Second most famous element: the smartphone battery! It is the wear item par excellence. The battery necessarily deteriorates over time. The new Li-Ion batteries no longer suffer from the memory effect as was the case with the first telephones. That is to say, you can charge it at any time, it will know where it is. Early Nimh batteries mistakenly thought they were fully charged when you unplugged them.


There are methods to better preserve its autonomy but it is undeniable, after 2 years, the autonomy is less good. No big deal, it’s easy to change your battery with SOSav !

Possible breakdowns: low battery life, charging problem, swollen battery / overheating.

The back of a smartphone protects the internal components from shocks and falls. It also prevents dust and other residues from infiltrating. A few years ago, the back cover was often clipped on and easy to remove. It is now a time gone. It is often a rear window (glass or plastic) that must be peeled off by heating it.

Possible breakdowns: broken hull, cracked rear window, rear face that no longer holds in place, etc.

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 mic which is used to pick up your voice during calls. It is not rare either, that the GSM antenna is also integrated there. A major piece.

Possible failures: charging problem, not recognized by the computer.

Loud speaker
smartphone speaker

There are two speakers on a smartphone. The listening loudspeaker (internal) which is located at the top. It delivers the sound of calls, that’s why it’s at ear level when you’re on the phone.

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 loudspeaker mode, etc.

Possible breakdowns: no sound, sizzling sound, cutting sound, distant sound.


Again, there are two cameras on one phone. The front camera (front) that is used for your selfies! It is located on the front side of your mobile.

And the rear (main) camera which is located on the back side. Generally, it has better resolution. Moreover, the latest smartphone models are even equipped with double, triple or even quadruple sensors 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 On / off, volume and sometimes even camera or fingerprint buttons . The buttons are generally pieces of plastic associated with a connecting layer . The tablecloth is often a separate element and the problem usually comes from it. It is she who creates the click and pressure effect to trigger the action of the button.

Possible breakdowns: torn tablecloth, broken button, button that no longer responds.

Internal frame

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 chassis is twisted, the screen and/or the back may be twisted too much and crack.

Possible breakdowns: twisted 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’s also at least one, if not two, secondary mics. Often associated with another component as well, such as a camera cable or proximity sensor for example. The secondary microphones are used for recording videos, voice assistants, dictaphone, etc.

Possible failures: no sound recorded, 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 parameters you have determined. If you notice that it no longer vibrates correctly or too weakly, is worn or following an impact, you must replace it.

Possible failures: no vibration, weak vibration, random vibration.
