Recognizing a Defective Earpiece

The internal earpiece of the Samsung Galaxy S10 5G is the speaker that reproduces sound during phone calls. You recognize it by its role: when you make a call, it is through this speaker that you hear the person on the other end. A defective earpiece manifests itself by complete absence of sound during calls, or very weak and distorted sound, while other audio sources (music, video, notifications) work normally. The phone correctly recognizes the incoming call, but the voice no longer comes out of this small speaker located at the top of the screen.

Before ordering a replacement part, verify that the problem is not software-related: test a call with speakerphone enabled, then switch to the internal earpiece. If sound returns on speakerphone but remains silent on the earpiece, the part needs to be replaced. This simple verification saves you an unnecessary order.

Specifications of this Compatible Part

This earpiece is a compatible part designed for the Galaxy S10 5G. Unlike an original manufacturer part, it is not extracted from a Samsung device but manufactured to fit this model. It offers a compromise between price and reliability: the customer obtains a functional speaker without the investment of an original part, while maintaining proven quality on this model. The Galaxy S10 5G shares its platform with several other models of the generation, which guarantees extended compatibility and production volumes sufficient to maintain quality.

This compatible part comes with a 2-year warranty in case of manufacturing or functional defect. The warranty covers material and workmanship defects, but does not apply to damage related to improper installation or phone drop after installation.

Installation and Precautions

Replacing the internal earpiece of the Galaxy S10 5G requires partial disassembly of the phone. The device must be completely powered off before any manipulation. The part is located under the screen, and access requires removing the entire display assembly, which involves handling fragile ribbons and connectors. An anti-static tweezers and quality thermal adhesive are strongly recommended to avoid short circuits or detachment after repair.

During installation, verify that no debris accumulates around the speaker: even a simple dust particle can muffle the sound of the new earpiece. After complete reassembly, perform a call test before returning the device to the customer, alternating between the internal earpiece and the speakerphone to confirm that both channels work.

Exact Model and Identification

This part is intended for the Galaxy S10 5G G977. This is the complete model you must look for on the old phone before ordering: in settings, go to "About phone" then "Model number". If you see "G977", you are on the correct model. The other S10 variants (G970 for the standard S10, G973 for the S10+, G975 for the S10e) use different parts and are not compatible with this earpiece.
