Resposta para "Rear Camera black/purple lines"Hi, After doing som diagnistic I found that the problem was related to PP2V85_RCAM_VDD. When I got the red lines this voltage was alternating. When the cam was black this voltage was zero. I changed the LDO U2301 without any change. So my guess is there is something wrong with the enable signal to the LDO from the A6. This is a straight trace without any vias, so monetoring this signal is difficult. This phone was not worth any more fault finding, so I have not got a 100% answer for the problem, but the 2.8 voltage was not present when the rcam was black so this signal path is my best guess;)
