Durability has always been a key concern when it comes to foldables, so Samsung uses a fleet of robots to ensure that everything works as expected – it did it last year and again this year for the new Galaxy Z Flip5 and Z Fold5.
It starts with the open and close test, putting the phones through 200,000 cycles (as verified by Bureau Veritas). Then comes the tumble test – the new Flex Hinge design includes a dual rail structure, which helps dissipate the force of an impact.
Next up, the water resistance trials – Samsung tests both IPX8 (submersion up to 1.5m/5ft for 30 minutes) and IPX4 (using nozzles to spray the phones with water). There’s a temperature and moisture test, then it’s back to surviving impacts in a drop test.
To wrap things up there are two display tests. The first is exclusive to the Galaxy Z Fold5 as it involves drawing with the S Pen. The last one is done to both – a steel ball is used to whack the display repeatedly to make sure it survives even outside of the protection of the clamshell design.
Don’t miss our hands-on review with the Z Flip5 and Z Fold5 (the Tab S9 slates and the new Galaxy Watches too). For the foldables, we also have a hands-on video.
