  Today's mobile devices contain densely packaged system-on-chips (SoCs) with
multi-core, high-frequency CPUs and complex pipelines. In parallel,
sophisticated SoC-assisted security mechanisms have become commonplace for
protecting device data, such as trusted execution environments, full-disk and
file-based encryption. Both advancements have dramatically complicated the use
of conventional physical attacks, requiring the development of specialised
attacks. In this survey, we consolidate recent developments in physical fault
injections and side-channel attacks on modern mobile devices. In total, we
comprehensively survey over 50 fault injection and side-channel attack papers
published between 2009-2021. We evaluate the prevailing methods, compare
existing attacks using a common set of criteria, identify several challenges
and shortcomings, and suggest future directions of research.
