A method includes identifying a first plurality of drive frequencies at which drive electrodes of a touch-sensitive display of an electronic device are driven, wherein the first plurality of drive frequencies includes a first frequency and a second frequency. A first noise value at the first frequency is determined. When the first noise value meets a first threshold value and the first noise value is less than a second threshold value that is greater than the first threshold value, a second noise value at the second frequency is determined by the electronic device and, in response to determining that the second noise value is less than the first threshold value, driving the drive electrodes at the second frequency. When the first noise value meets the second threshold value, a third frequency at which the drive electrodes are driven is identified by the electronic device, wherein the third frequency is not one of the first plurality of drive frequencies.

Electronic device and method of identifying frequency for detecting touches

Methods and electronic devices for providing a wallpaper viewfinder are described. In one aspect, a method includes: receiving image data from a camera of the electronic device; displaying a viewfinder for the camera on a display of the electronic device based on the image data; identifying a subject in the image data; and overlaying one or more interface element representations on a portion of the displayed viewfinder which does not contain the identified subject, the interface element representations depicting interface elements associated with a graphical user interface of the electronic device.
