ASUS - ZenTalk

My settings app is crashing each time I try to open the developer options ! I tried to re-start the phone and open again but it still continues to crash. Please Guide ! You can find the disclaimer I was talking about in the screenshot attached. Pleas...

Whenever i take photos at night in the artificial lighting (in the tubelight lighting) using 48 MP (In my Asus 6z)......the image processing tends to blacken the picture. How to get over this ? Please help !
