Is your smartphone charging slowly, requiring you to hold the cable at an angle, or not accepting a charge at all? This Realme C31 Charging Logic Board Sub-Board is the complete replacement module needed to solve your power and audio input problems in one step.
Located at the bottom of the device, this secondary logic board houses the charging port, primary lower microphone, 3.5mm audio jack, and cellular antenna contacts. Replacing the entire board assembly is faster, cleaner, and far more reliable than soldering individual micro-components.
