Important compatibility and installation notes
Match the phone model, connector layout and original cable before ordering. This cable is not the charging-port board, display flex or antenna flex. A similar symptom can have several causes, so diagnose the device before replacing parts.
Professional installation is strongly recommended. Disconnect the battery before internal work and use suitable ESD precautions. Installation damage, torn flexes and damaged connectors are not manufacturing defects.
