Yes I did but the problem is still there the keyboard do not respond for seconds and sometimes dobles words or letters I believe it is not the screen cover because works most of the times thank you
If you're using a 3rd party plastic screen protector, or a Tempered glass screen protector, that doesn't use edge to edge adhesive, that could certainly cause issues, even if only intermittently.
I use Whitestone Dome Tempered Glass screen protectors, and never had any issues with the Touch Screen or Finger Print Sensor.
