Various sources have confirmed that both Galaxy Z Fold 3 and Galaxy Z Flip 3 meet the IPX8 waterproof standard, which means that these two foldable phones will be completely waterproof. Although the device is not dustproof, the waterproof level is the same as that of the Galaxy S21 Ultra series, and it can work normally for 30 minutes at a depth of 1.5 meters.
As for dust resistance, it’s not that Galaxy Z Flip 3/Z Fold 3 can’t accept dust at all. The “X” code only indicates that the phone has not been tested in this area. These tests were carried out under laboratory conditions.
Despite this, Samsung may also make progress in this area. The general expectation is that these two foldable smartphones will be equipped with new hinges and a particularly strong armor frame to make the device waterproof.
The full name of IP here is Ingress Protection. The IP protection level is composed of two numbers. The first number indicates the level of protection against dust and foreign objects (the foreign objects referred to here include tools, human fingers, etc., are not allowed to touch the live parts of the electrical appliances.
To avoid an electric shock, the second number indicates the degree of airtightness of the electrical appliance against moisture and water immersion. The larger the number, the higher the degree of protection.
By the way, did you know that Samsung was the first manufacturer to release a waterproof smartphone? It was 10 years ago that Samsung Galaxy XCover was proposed as an IP67-level rugged mobile phone. In a few months, Sony will launch a similar Xperia Go phone.
Five years later, the first Galaxy S series smartphones also obtained IP certification. The Galaxy S7, launched in 2016, is the first Samsung smartphone with an IP68 rating. Since then, all top models of the brand have been assigned an IP rating. This is an important innovation because since then, we can also take our beloved phones to take a bath, to the swimming pool, or even to the beach.
