i bought an OEM Screen protector, it looked good, and i noticed the sides not sticking... but the worse was that the proximity sensor was blocked. they cutted the edges for the iris scanner, not the proximity sensor... I was annoyed and the seller threw all the screen protector for the lumia 950 xl to the trash (and he gave me a refund)...
I need a screen protector, i have a daughter of 1.5 years, and it's like a tornado, she broke my wife's 620 (and was an excuse to buy the 640 xl) and scratched my 920... i don't want my 950 xl to suffer the same fate...
