If the electromagnetic head of the mobile phone wireless bracket falls off, first confirm whether it is still within the warranty period, if so, you can contact after-sales service for repair or replacement. If it has passed the warranty period, you can try to repair it yourself, you can use glue to stick it back in place, or buy the same type of electromagnetic head to replace it. If the above methods are not feasible, it is recommended to contact the manufacturer or professional maintenance shop for maintenance. At the same time, pay attention to avoid violent vibration and collision when using, so as to avoid falling again. I hope it helps you out.
