iPhone screen only works if I hold it
Hello all, I have replaced my Iphone 5S screen after the original failed. After the screen had been attached to the phone I have noticed that the screens touch is not responsive if the phone is sitting on a table and not being held or touched by any other part of my other hand. In other words I have to be holding the phone in one hand and using the other on the screen to get a response. It's almost as if I need to make the circuit from finger to phone case to get a response from the screen. I have tried the screen with different phones and the same thing happens. Has anyone ever come across this before and do you know what is happening. I should also add that when the phone is connected to it's charger then everything works fine. The screen swipes and all functions work. As soon as I disconnect the charger then nothing works on the screen unless I am holding the frame of the phone with my other hand.
