I know this is an old post. I have a s9+ and just got a gadget guard black ice and cornice edition. Go to settings, advanced features then at the very bottom and make sure the touch sensitivey option is on. The option will say for use with screen protectors. I started with not being able to type after I installed the protector to now it types perfectly fine. Hope this helps any one in the future.
I had the problem. I took off the gel case protector from the back and realized it had forced the glass screen saver up of the phone glass just a fraction but that fraction made it very hard to make good contact. I put it back on very careful not to raise the glass screen saver and it works just like it should
I'm past frustrated the #1 issue with this phone is how easy it is to crack.
I HAVE NO SCREEN PROTECTOR and still tap tap tap tap...the solution provided settings》Nav 》increase sensitivity apparently doesn't exist on my phone(and In not going to easy mode) Any game with an ok/collect/ redeem box tap tap tap.I'm about to transfer everything back To my S4 and get an exchange.
