Abstract

Kirk and Fred discussing the recent failures of the new folding Samsung Galaxy phone and what might have been missed in their testing video.

Key Points

Join Kirk and Fred as they discuss the newly introduced folding smartphone screen and it’s testing that did not reveal the failures that early customers observed and required Samsung to recall all of the first units.
Topics include:

• The automated setup that Samsung published that showed several phones making uniform repeated opening and closing 200,000 times and how this did not show the later problems customers experienced
• We know that polymers mechanical flexing properties are strongly affected by temperature and temperature
• The pressure to be first to market with a new technology, folding screens, has now backfired and may cost them more in lost early sales and adoption of a new technology when they do solve the reliability problems in the future.

Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques, to field data analysis approaches.
