I just recently discovered that the lighting of the front camera when on video mode is so much better than taking an actual photo. So if you use video instead of photo when taking a selfie… you’re actually going to get better results. It’s not going to look dark and grayish, AND YOUR PORES AND WRINKLES ARE NOT HIGHLIGHTED. Also, you can just pick the video frame where you look the best.
I’ve noticed this a lot as well. I just take a screenshot in the camera app instead of actually taking a photo.
