Apple vs. Samsung: Ambient Light and Proximity Sensing Devices Comparison - Complete Teardown Report 2018 -


The "Apple
vs. Samsung: Ambient Light and Proximity Sensing Devices Comparison
Complete Teardown Report"
report has been added to's

Behind the screen, latest Apple's smartphone is better than Samsung's
thanks to the Ambient Light Sensor (ALS), which allows better color
management of the display. ams AG and STMicroelectronics are the leading
suppliers of ALS and proximity sensors for consumers. Both are
implicated in the supply chains of Samsung's and Apple's latest

The publisher has conducted a comparative review of the ALS and
Proximity Sensor in the latest three flagships smartphones from Samsung
and Apple. We analyze and compare the Samsung Galaxy S7, Galaxy S8 and
Galaxy S9 the Apple iPhone 7, iPhone 8 and iPhone X. We provide insights
into the structure, technical choices, design, processes, supply chain
positions and costs.

Of the two OEMs, Samsung has chosen to combine the two sensors in a
single component, whereas Apple made the choice to keep them separate.
Over the years, Samsung has improved the performance without changing
its packaging footprint. Apple has kept the same supplier,
STMicroelectronics, for its proximity sensor. However it has added
features to each new generation, as in the latest the iPhone X, where
the proximity sensor is combined with a flood illuminator. In this new
iPhone the ambient light sensor is still supplied by ams, but has a
multi-spectral feature.

This report includes an analysis of the packaging and the sensor die
along with a cost analysis and a price estimate for the all devices.
Finally, we compare device evolution by OEM and a cross-comparison to
highlight their choices.
