How can i do mantainance of semi board of smart phone 📱 either replacement of charging system without destroying others on the board or external speaker of mi phone
Check you my 'CHARGING PROBLEM' play list, the is one video that shows that. However after watching, and you still have any specific questions let us know so we can make a video specific to your query
check out the connection to the speaker , or any resistor leading to the speakers . Also if you don't mind my asking ; which brand or model is the phone ?
