820-3437 no camera u3900

Yoel Ren

hi, Im seeing a few post saying to live with camera because it's too risky right ?
as an iphone technician who have tried repair ip6+ touch issue, ip 7 audio issue, i think u3900 should be easier compared to that right ? or not ?correct me if im wrong.
well anyway does anyone have a stencil for this chip?


Yeah I don't know why people say to leave U3900 alone; I've replaced dozens of them and it DOES fix the camera issue 95% of the time (assuming no damage elsewhere, connector is good, etc). It's not hard at all. You can find stencils all over for it; search chip part# and you'll find it. I don't have schematics in front of me.
