A mobile device user is having problems launching apps and texting. The user touches an app to launch it, but the app icon next to the desired app launches instead. When the user types a text message, every word in the message is misspelled. What is the most likely cause for this behavior?

The screen protector may be interfering with the touch response

Explanation:

Screen protectors or commonly called screen guards are used to protect phone screens. In case they fall to the ground, these protectors act as shields to keep the phone screen from getting damaged. However screen protectors if not positioned or fixed properly may also cause hindrance to effective touch response as they become barriers to the touch screen.
