Hello Manas,
Thank you for posting your concern. Are there any heat sources around the sensor that could be contributing to the temperature measurement? Isolate the temperature sensor away from other heat sources around the board and increase the thermal conductivity between the sensor and the skin. I would maximize the thermal response of the sensor by reducing the PCB area around the IC. Providing cut outs around the sensor can help increase the thermal response time or using a flex PCB. One important note when it comes to restarting the device, the sensor will restore to default settings. To further understand your issue, I can provide more guidance if you provide a log of your I2C transitions, and a diagram of how you are placing your temperature sensor.
