So I noticed the led flash doesn’t helps much, overall what am trying to say is don’t expect much from the camera, at some conditions camera captures good image and at some conditions the camera captures not so happy image, it works somehow good in daylight and if you want to enjoy the battery you must keep the screen brightness very very low like below 5%ledflash is good not yellowish, but still when you click with flash at night or at low-light the image gets yellowish, you can solve this by trying different camera setting, changing white balance from auto to fluroscent and try different iso, the camera is not much smart, and also the battery is good but don’t forget since the phone is full hd display the screen consumes many battery, so even though its 4000 mah screen consumes so much battery so for example it might feel like about 3200 mah not 4000mah, one more thing, the led is good very bright and not yellowish, but when you capture image at lowlight the image comes out somehow little yellowish, its not because of the led, its because of the camera’s settings and combination, for example you can try different white balance, if you keep cloudy then the image becomes more warm and yellowish, if you keep fluroscent the image comes out bluish and cold, try different setting if you get yellow image, and the image comes darker with led flash even though the led flash is very bright, , then the battery don’t drop fast it’s very good then, and the touch experience feels weird sometimes
