I've been servicing and fixing cell phones and other mobile devices since 2012 with a very high level of success. I've been in the mainstream retail business both in the wholesale market and the public consumer market as far as the purchasing and selling of parts and devices. I have a background in programming and the operational functionality of applications and their use and viability. I've been building computers and similar systems and devices since the end of the 70's, so I do have a vast amount of experience and knowledge about the physical features and functions of electronics.
