Investigating the Influence of CPU Load, Memory Usage and Environmental Conditions on the Jittering of Android Devices

Abstract

Over the last decade, the smartphone has become an important part of our everyday lives and is used even in the most rural regions. The use cases of this device go far beyond communication for which they were mainly designed. It can, e.g., be used for activity recognition or serve as a measuring device. However, for these use cases, smartphones might suffer difficulties such as jittering. Jittering is the deviation between the time an event occurs and the time the event is reported by the device. In this paper, we investigate the influence of environmental conditions such as heat as well as the processor load and memory usage on jittering. With this work, we want to contribute to a better understanding of jittering and its influencing factors.
