Systems and methods to calibrate a handheld device used for remotely controlling a vehicle

A method comprising:

• entering a first remote-control command into a first handheld device for controlling a first action performed by a vehicle;
• measuring a first time-delay associated with a first operation executed in the first handheld device in response to entering the first remote-control command;
• and
• calibrating the first handheld device, the calibrating comprising comparing the first time-delay to a first threshold time value.

A handheld device comprising:

• a memory that stores computer-executable instructions;
• and
• a processor configured to access the memory and execute the computer-executable instructions to at least:
• detect a first remote-control command that is entered into the handheld device for controlling a first action performed by a vehicle;
• measure a set of time-delays associated with operations executed in the handheld device in response to entering the first remote-control command;
• convey the set of time-delays to a cloud computing device;
• receive from the cloud computing device, a diagnostic result based on an evaluation of the set of time-delays;
• and
• calibrate the handheld device based on the diagnostic result.
