In aspects of replay of recorded touch input data, a computing device can store recorded touch input data that has been previously recorded based on multiple instances of user inadvertent contact on touch-enabled devices. A replay test application is implemented to test one or more user devices for inadvertent contact rejection using the recorded touch input data, such as to test a palm rejection algorithm of a user device. The replay test application is implemented to communicate the recorded touch input data to a screen overlay device that generates touch inputs on a touchscreen of the user device to test the palm rejection algorithm of the user device. The replay test application also monitors the user device for an action responsive to a touch input that is not filtered as an inadvertent contact with the touchscreen of the user device.
