Indoor localization has been gaining popularity, with its potential use cases it offers due, to the rise of Internet of Things (IoT) and drive for ubiquitous connectivity. On the other hand, recent advancements on phone inertial measurement unit has increased significantly, resulting in more accurate measurements. In this paper, tests are conducted on a Samsung S21 smartphone to determine the accuracy of its accelerometer and gyroscope. The raw IMU data are compared against ground true values and processed for further analysis. A calibration step is also included in the test to reduce the accumulated errors. The paper is able to show even with increase in distance, the localized processed data is shown to be more accurate with calibration.
