1. A touch region adjustment method implemented by an electronic device, wherein the touch region adjustment method comprises:
receiving, on a touchscreen of the electronic device, a first touch input;
determining a first contact surface of the first touch input, wherein the first contact surface is located on a side screen on the touchscreen;
obtaining first touch information of the first contact surface, wherein the first touch information comprises capacitance information and one or more of a first height of the first contact surface, a first width of the first contact surface, or an area of the first contact surface;
determining, based on the first touch information, a touch region and a first non-touch region on the side screen, wherein a first distance between the touch region and the first contact surface comprises a first distance value, and wherein the first non-touch region comprises the first contact surface;
determining that the touch region is located between a first end of the side screen and the first contact surface when a second distance between the first contact surface and the first end is greater than or equal to a first preset value;
determining that a type of the first contact surface is a thenar contact surface when the first touch information meets a first preset condition, wherein the first preset condition comprises that:
the first height is greater than a first height threshold and a first ratio of a first capacitance value of a most edge coordinate column of the first contact surface to a second capacitance value of a secondary edge coordinate column of the first contact surface is within a first ratio range, wherein a first value in the first ratio range is greater than or equal to 1, wherein the most edge coordinate column is closest to a long side of the electronic device and in a touchscreen array corresponding to the first contact surface on the touchscreen, and wherein the secondary edge coordinate column is second closest to the long side and in the touchscreen array;
the first height is greater than the first height threshold, a second ratio of the first height to the first width is greater than a first height ratio, and the first ratio is within the first ratio range; or
the second ratio is greater than the first height ratio, the area is greater than a first area threshold, and the first ratio is within the first ratio range;
receiving, on the touch region, a second touch input;
displaying, in response to the second touch input, a first user interface;
receiving, on the first non-touch region, a third touch input; and
skipping changing, in response to the third touch input, display content on the electronic device.
