Ane of the well-nigh important updates to the Samsung Galaxy Z Fold 3 and Galaxy Z Flip iii this year are their waterproof ratings. And its a feature other foldable phones really demand to steal.

While Samsung hasn't testify how information technology managed to waterproof its fodables, YouTube channels iFixIt and JerryRigEverything have taken the Galaxy Z Fold 3 autonomously in 2 to show how water is kept at bay. If you lot tin stomach watching them rip into $1,800 phones, then it's a fascinating await into how folding phones piece of work and how Samsung accomplished the IPX8 ratings.

Because foldable phones by pattern have big gaps in their frames to allow the folding to happen, Samsung'due south arroyo was to make certain everything by that point is sealed up. For example, the cables that attach the display to the motherboard are surrounded past a perimeter of agglutinative, making sure water can't infiltrate the phone through here.

In that location are safety gaskets, held in identify by a silicone adhesive, surrounding the cables running through the hinge on the Galaxy Z Flip 3. The JerryRigEverything video found a similar ane located behind the Milky way Z Fold 3's ability button/fingerprint sensor. These seem to be the chief line of defence force against water, alongside waterproof screens over microphone and loudspeaker openings. And more than rubber gaskets around the speakers, SIM card squirt port, SIM tray and charging port.

While these measures don't finish h2o from getting into the phones, information technology should end them from being damaged by it. For example, you tin can see in iFixit's video that some h2o got under the Galaxy Z Flip three's display after existence submerged, although due to these measures, those droplets shouldn't interfere with the circuitry.

In that location has been some suspicion that Samsung used a hydrophobic coating on the motherboard of its new foldables as another method of protection. However, when Zack of JerryRigEverything dropped some water onto the circuitry of the Milky way Z Fold three, the drops stayed put, significant in that location wasn't any waterproofing on the inner parts of the telephone.

These teardowns also testify off the phones' principal line of defense force against dust — nylon brushes that line the hinge. These aren't enough to grant the phones a dust resistance rating, but should hopefully prevent any particles from wrecking the hinge.

We accept yet to test how waterproof the Milky way Z Fold 3 or Z Flip 3 are for ourselves, other than the odd rinse nether a tap, merely watch out for hereafter tests. While we had no reason to doubtfulness Samsung's claims virtually waterproofing its new foldables, information technology'south fascinating to meet how it's slowly making this new form factor more than refined. We just need other foldable phones to follow suit and offering compelling alternatives to Samsung's latest Android flagships.
