I just bought to a new replacement screen and now my right side randomly stops working. The old screen was crushed by a chair, can anything inside the phone cause it to hurt the new screen

hello Idalla, No, it can not. You have probably inserted the touch connector incorrectly or the touch function has been damaged. This is most often the first. Disconnect the connectors again (start by disconnecting the power supply - always) and try. Don’t press, you will hear a soft “click”. This means that everything is in place. Connect the battery and check. If touch cannot be restored, it could be a mechanical failure on the other (bottom side of the motherboard) side. Do not put anything under the connectors (sometimes people use a flat screwdriver to remove the contact - this is a mistake that costs quite a lot).
