Dark spot on all my pictures; damaged camera sensor?
.A dark spot developed on my Idol3 camera's viewer and is captured in subsequent photographs. The lens was cleaned thoroughly without any change. The spot can be bypassed by zooming in, so I suspect a damaged area on the sensor. No known drops or impacts related to the development of this issue. If it is the sensor, can it be repair/replaced at a cost that is worthwhile for a two-year old unit?
Es esta una buena pregunta?
