I just installed this screen protector on my new device and it was easy and I had no problems. I tried using a frame but found it very difficult to make minor adjustments and make sure you are even perfect so I threw it away just looked at it and it worked fine. Because the S6 Lite has only one center cutout and the glass is strong and won't bend, it's easy to install. I lined the top, removed all the adhesive backing and put the coverslip on, literally just watching it fit perfectly top to bottom and just had to pop a bubble out. The touchscreen/pen functionality was not affected in any way (I've only used it during the day so far).
