Several charactears appear when I press only one

  • Hi!

    I'm enjoying my Edison 3 since a few weeks ago. Since yesterday, when I press a key on the screen, it appear more than one character, and it's impossible to write any text. I've cleaned up the screen and rebooted the tablet, but the problem remains.

    Thanks in advance for your answers!

  • Hi, in development options calibrates the screen. Or adjustments.
