Hi, My name is Rajesh Behera. I am the founder of RepairTheMobile. I am a Mechanical Engineer and currently working in an MNC. Mobile phone repair is my passion. There are a lot of mobile phone repair videos available on YouTube. But most of these videos are not properly explained due to the lack of proper knowledge of the technicians. Due to the demand for mobile phones, lots of new mobile technicians are opening their repair shops. They are only doing basic works like combo (display screen) replacement, charging port change, battery replacement, etc. They don’t know the proper way of finding faults like dead phone repair, backlight & graphics issues, network problems etc. They cannot close their shops to get offline training. So, I decided to make RepairTheMobile to help new mobile technicians. RepairTheMobile is absolutely free learning platform. It offers FREE mobile repair training from basic level to advanced level. Keep learning & keep earning.
