NOTE: When you apply a screen protector and are having trouble with the touchscreen, there's a setting you can toggle on to help. Head to Settings -> Advanced features -> Touch sensitivity to toggle it on. It increases the touch sensitivity, making the screen more reactive even with a screen protector applied over the display. To double-check the model of your Samsung device go to Apps -> Settings -> More/About Device. Tap that feature and you will see the model type and the number of the device. Installation Instructions: Please use the provided alcohol swab and micro fabric to clean the LED screen of your device before the installation of the screen protector. Carefully peel off the protective layer of the adhesive side. Critically align the tempered glass to the screen. Carefully keep pressing down around the edges of the screen protector to make sure the adhesive sticks properly and firmly to the screen. Cautions: This is a glass product so the edges of the glass are the most vulnerable areas. It is not recommended that this tempered glass is reused once it is applied as its adhesive properties might wear off resulting in the screen protector not adhere to the device.
