Abstract

Embodiments of the present disclosure disclose a terminal anti-lost method and a terminal, to resolve a problem that a lost terminal is difficult to find when a user discovers in a timely manner that the terminal is lost. The method in the embodiments of the present disclosure includes: first detecting, by the terminal when receiving a specific instruction, whether the terminal is currently in a lock screen state, where the specific instruction represents an instruction of controlling the terminal to decrease volume and/or an instruction of preventing the terminal from receiving a carrier signal; and skipping executing, by the terminal, the instruction when it is determined that the terminal is in the lock screen state, and controlling the terminal to increase the volume and/or play an alarm tone by using a loudspeaker.

Claims

1. A terminal anti-lost method;

comprising;

receiving, by a terminal, a specific instruction, wherein the specific instruction comprises at least one of;

an instruction of controlling the terminal to decrease volume or an instruction of preventing the terminal from receiving a carrier signal;

detecting, by the terminal, whether the terminal is currently in a lock screen state; and

skipping executing, by the terminal, the specific instruction when the terminal is in the lock screen state; and

controlling the terminal to increase a volume and/or play an alarm tone from a loudspeaker.

2. The method of claim 1, wherein the instruction of controlling the terminal to decrease volume comprises one or more of:

a switch-off instruction, a mute instruction, or a volume decreasing instruction, and wherein the instruction of preventing the terminal from receiving a carrier signal comprises one or more of;

the switch-off instruction or a SIM-card removing instruction.

3. The method of claim 1, further comprising:

detecting, by the terminal, headset insertion; and

deactivating, by the terminal, the headset insertion when the terminal is in the lock screen state.

4. The method of claim 3, further comprising:

prompting, by the terminal, a user to cancel the lock screen state of the terminal prior to deactivating the headset insertion; and

deactivating the headset insertion when the lock screen state of the terminal is not canceled in a predetermined time.

5. The method of claim 1, further comprising:

prompting, by the terminal, a user to cancel the lock screen state of the terminal prior to skipping executing the specific instruction; and

skipping executing, by the terminal, the specific instruction, when the lock screen state of the terminal is not canceled in a predetermined time.

6. The method of claim 1, further comprising:

obtaining, by the terminal, a biometric feature; and

uploading the biometric feature to a server, and/or sending the biometric feature to another terminal.

7. The method of claim 1, further comprising:

obtaining, by the terminal, an environmental parameter of an environment in which the terminal is located; and

uploading the environmental parameter to a server, and/or sending the environmental parameter to another terminal.

8. The method of claim 1, further comprising stopping playing, by the terminal, the alarm tone when the lock screen state of the terminal is canceled.

9-16. -16. (canceled)

17. A terminal, comprising:

a loudspeaker;

an input device;

a memory; and

a processor coupled to the loudspeaker, the input device, and the memory, wherein by invoking an operation instruction stored in the memory, the processor is configured to;

receive a specific instruction, wherein the specific instruction comprises at least one of;

an instruction of controlling the terminal to decrease volume or an instruction of preventing the terminal from receiving a carrier signal;

detect whether the terminal is currently in a lock screen state;

skip executing the specific instruction when the terminal is in the lock screen state; and

control the terminal to increase a volume and/or play an alarm tone from the loudspeaker.

18. The terminal of claim 17, wherein the instruction of controlling the terminal to decrease volume comprises one or more of:

a switch-off instruction, a mute instruction, or a volume decreasing instruction, and wherein the instruction of preventing the terminal from receiving a carrier signal comprises one or more of;

the switch-off instruction or a SIM-card removing instruction.

19. The terminal of claim 17, wherein the processor is further configured to:

detect a headset insertion; and

deactivate the headset insertion when the terminal is in the lock screen state.

20. The terminal of claim 19, wherein the processor is further configured to:

prompt a user to cancel the lock screen state of the terminal before deactivating the headset insertion; and

deactivate the headset insertion when the lock screen state is not canceled in a predetermined time.

21. The terminal of claim 17, wherein the processor is further configured to:

prompt a user to cancel the lock screen state of the terminal before skipping executing the specific instruction; and

skip executing the specific instruction when the lock screen state is not canceled in a predetermined time.

22. The terminal of claim 17, wherein the terminal further comprises a transmitter;

and wherein the processor is further configured to;

obtain a biometric feature; and

transmit the biometric feature to a server, and/or transmit the biometric feature to another terminal.

23. The terminal of claim 17, wherein the terminal further comprises a transmitter;

and wherein the processor is further configured to;

obtain an environmental parameter of an environment in which the terminal is located; and

transmit the environmental parameter to a server, and/or transmit the environmental parameter to another terminal.

24. The terminal of claim 17, wherein the processor is further configured stop playing the alarm tone when the lock screen state is canceled.
