Stunning Homtom HT20 Water Test: Survived Under Water For 60Minutes, Can Your Phone do That?

Meet a phone that stay in water For 2 Minutes.I am so impressed with the build of this smartphone and also I guess there are very few smartphones out there that can survive this test.
This is the next midrange flagship of HomTom called HT20. The construction apparently uses some vacuum technology making the phone sturdy and resistant to water.
Today, I came across a video of HomTom HT20, which survives an hour-long submersion under water.
Watch the video below:

Though the video has been edited for, so you don’t have stare for complete 60Minutes.
HT20 is a mid-range smartphone, 2GB ram, 16GB rom 4.7 inches with 8MP rear camera and support for finger print ID.
Can your smartphone even survive 4Minutes inside water?
