I recently purchased a S7 and found the touchscreen very hard to use, very low sensitivity. I tried the #*#2663 (whatever the code is) to bring up the menu, update and tried it. After adding a Zagg tempered glass screen protector it's barely usable now. Removing the screen protector is not am option, I work in construction and must keep this phone protected. Is there any other way to make the touchscreen more sensitive? Texting is nearly impossible!
