I am facing trouble with camera. Camera is not working in any apps such as instagram, whatsapp & snapchat. The inbuilt camera of Nokia 7 plus shows "camera can't open error". Everything was working fine, out of nowhere all these errors started showing up. There is no virus in my phone nor did i receive any system update or any sort of other updates. Its just 2 months back that I have purchased this phone. Goshhh!! whats going on Nokia ?
