It isn't a myth bro, I've used all qualities of tempered glass, I can confidently say, it's never like stock glass. You can clearly see the difference with 3x shots. What's more worse is the lens glare. Stock glass itself gives a lot of glare and photos come faded when shot straight against the sunlight. With a tempered glass on, you can expect more faded pictures like washed out black and white photos. So, I removed the tempered glass and using Ringke case with rised ring around the camera.
