When your Samsung Galaxy S23 Plus 5G begins to lose signal or suffers from low audio during calls, the problem often lies in the internal hardware. One of the most overlooked yet essential components is the antenna board and earpiece speaker.
The Antenna Board Upper Left Corner Earpiece Speaker is responsible for ensuring strong signal reception and delivering crisp sound during calls. If your phone has recently been dropped or exposed to moisture, this part may be damaged — leading to connectivity and audio problems.
Many users mistakenly believe they need a new phone when signal issues arise. But in many cases, a simple part replacement solves the problem. This is especially true for the Galaxy S23 Plus 5G, where modular parts make repairs efficient and cost-effective.
Replacing the upper left antenna board improves the phone’s ability to detect and hold a strong mobile signal. At the same time, the earpiece speaker ensures voices sound clear and undistorted. Together, these improvements can completely transform the way your phone performs.
You may be a technician looking for a reliable part or a phone owner trying to restore functionality. Either way, using OEM-quality components ensures long-term performance and compatibility with your Samsung Galaxy S23 Plus 5G.
The best part? This upgrade doesn’t require a full motherboard replacement. Instead, it targets the issue directly — saving time, money, and stress. It’s an ideal fix for calls dropping, muffled voices, or total earpiece failure.
Whether you’re buying it for personal use or to stock in your repair shop, this small but powerful component offers big benefits.
