I have bought a new screen protecter. Mirror screen protecter and when i touch the screen to use the phone while it is flat on the floor it doesnt respond. Only when i have the phone in my hand it responds...
It has to be grounded to respond to touch like plugged into a charger or computer or in your hand I beleive

Exactly. It has a capacitive screen; it registers your touch by measuring the electrical interference your finger makes. If there is nothing to complete the circuit (see quote), the phone won't respond.
