The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

Processor 110 may include one or more processing units, such as: the processor 110 may include an Application Processor (AP), a modem processor, a Graphics Processing Unit (GPU), an Image Signal Processor (ISP), a controller, a video codec, a Digital Signal Processor (DSP), a baseband processor, and/or a neural-Network Processing Unit (NPU), etc. Wherein the different processing units may be separate components or may be integrated in one or more processors. In some embodiments, the electronic device 101 may also include one or more processors 110. The controller can generate an operation control signal according to the instruction operation code and the time sequence signal to complete the control of instruction fetching and instruction execution. In other embodiments, a memory may also be provided in processor 110 for storing instructions and data. Illustratively, the memory in the processor 110 may be a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory. This avoids repeated accesses and reduces the latency of the processor 110, thereby increasing the efficiency with which the electronic device 101 processes data or executes instructions.

The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor, the capacitance between the electrodes changes. The electronics determine the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 160, the electronic device detects the intensity of the touch operation according to the pressure sensor. The electronic device may also calculate the position of the touch from the detection signal of the pressure sensor. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message.

For example, when the temperature reported by the temperature sensor exceeds a threshold, the electronic device performs a reduction in performance of a processor located near the temperature sensor, so as to reduce power consumption and implement thermal protection. In other embodiments, the electronic device heats the battery 200B when the temperature is below another threshold to avoid abnormal shutdown of the electronic device due to low temperature.

Wherein the first protocol stack performs a third radio frequency handover operation, comprising: the first protocol stack informs the processor of executing the radio frequency switching operation through the modem, so that the processor is connected with the first SIM card through the electronic switch and disconnected with the second SIM card through the electronic switch, and the purpose of switching the mobile radio frequency module from being in communication connection with the second SIM card to being in communication connection with the first SIM card is achieved.
