What is ghost touch iphone?

Ghost touch on an iPhone occurs when the device registers touches or swipes on the screen without any actual physical touch. This can be caused by several factors, including faulty hardware such as a damaged or malfunctioning digitizer, software glitches or bugs, or even interference from an external magnetic field. Ghost touch can be annoying and disruptive, making it difficult to use the device properly. It can sometimes be resolved by resetting the iPhone, updating the software, or by having the hardware repaired or replaced.
