🗼📱Samsung S23 Ultra Signal Repair: Sub-Board FPC Connector Replacement (No 4G/5G)😍

Check out this repair on a Samsung Galaxy S23 Ultra that arrived at our shop with no mobile network service (no SIM card signal, 4G, or 5G). During hardware diagnostics under the microscope, we identified a damaged corner on the sub-board's FPC connector (charging port board). Instead of replacing the entire sub-board with a low-quality aftermarket part, we performed micro-soldering to replace only the damaged FPC connector. This approach preserved the phone's original sub-board, maintaining factory RF (Radio Frequency) performance, microphone quality, and circuit integrity. The 4G/5G mobile data was fully restored and tested! #SamsungS23Ultra #MicroSoldering #BoardRepair
