1. A method of detecting a protective film, comprising:
- collecting a signal change level of a touch screen, the signal change level comprising a difference between a signal level generated from a touch operation and a signal level generated from no touch operation; and
determining that a protective film has been attached to the touch screen upon the signal change level satisfying a preset condition, wherein;
the preset condition comprises a signal change level of a reference touch screen attached with a protective film, and the determining that a protective film has been attached to the touch screen upon the signal change level satisfying a preset condition comprises;
determining that the protective film has been attached to the touch screen upon a difference between the signal change level of the touch screen and the signal change level of the reference touch screen being not greater than a preset threshold, the preset threshold being used to indicate a fluctuating range of the signal change level of the touch screen attached with the protective film, andprior to collecting a signal change level of a touch screen, the method further comprises;
collecting signal change levels of touch screens equipped on a plurality of smart devices; and
performing statistics for a plurality of signal change levels falling within a preset range among the collected signal change levels, and obtaining a statistical value as the signal change level of the reference touch screen, the preset range being used to indicate a range of the signal change level of the touch screen attached with the protective film.

15. A protective film detection apparatus, comprising:
-
a processor; and memory for storing instructions executable by the processor; wherein the processor is configured to; collect a signal change level of a touch screen equipped on a smart device, the signal change level being a difference between a signal level generated from a touch operation and a signal level generated from no touch operation; and determine that a protective film has been attached to the touch screen when the signal change level satisfies a preset condition, the preset condition being used to indicate a condition that a signal change level of the touch screen attached with the protective film needs to satisfy, wherein; the preset condition comprises a signal change level of a reference touch screen attached with a protective film, and the determining that a protective film has been attached to the touch screen upon the signal change level satisfying a preset condition comprises; determining that the protective film has been attached to the touch screen upon a difference between the signal change level of the touch screen and the signal change level of the reference touch screen being not greater than a preset threshold, the preset threshold being used to indicate a fluctuating range of the signal change level of the touch screen attached with the protective film, and prior to the collecting a signal change level of a touch screen, the processor is further configured to; collect signal change levels of touch screens equipped on a plurality of smart devices;
perform statistics for a plurality of signal change levels falling within a preset range among the collected signal change levels, and obtain a statistical value as the signal change level of the reference touch screen, the preset range being used to indicate a range of the signal change level of the touch screen attached with the protective film. - View Dependent Claims (16)

17. A non-transitory computer-readable storage medium having stored therein an instruction that, when executed and performed by a processor to perform the following operations:
-
collecting a signal change level of a touch screen equipped on a smart device, the signal change level being a difference between a signal level generated when a touch operation is triggered on the touch screen and a signal level generated when no touch operation is triggered on the touch screen; and determining that a protective film has been attached to the touch screen upon the signal change level satisfying a preset condition, the preset condition being used to indicate a condition that a signal change level of the touch screen attached with the protective film needs to satisfy, wherein; the preset condition comprises a signal change level of a reference touch screen attached with a protective film, and the determining that a protective film has been attached to the touch screen upon the signal change level satisfying a preset condition comprises; determining that the protective film has been attached to the touch screen upon a difference between the signal change level of the touch screen and the signal change level of the reference touch screen being not greater than a preset threshold, the preset threshold being used to indicate a fluctuating range of the signal change level of the touch screen attached with the protective film, and prior to the collecting a signal change level of a touch screen, the instruction is executed and performed by the processor to perform; collecting signal change levels of touch screens equipped on a plurality of smart devices;
performing statistics for a plurality of signal change levels falling within a preset range among the collected signal change levels, and obtaining a statistical value as the signal change level of the reference touch screen, the preset range being used to indicate a range of the signal change level of the touch screen attached with the protective film.
