The video is 2 minutes and 6 seconds long and features a buzzing sound that may cause your phone to vibrate a little.
The people who commented under the video can’t stop raving about how well it works every time their phone gets wet.
The phones were first submerged in a UV bath for about a minute, after which they were tapped to expel some water, and then a video was played of water being expelled. The phones were left out overnight before being checked to see where there was any residue of the UV dye left, to find out where there was still liquid.
The results were mixed. Pixel 7 Pro was completely dry, the Nokia 7.1 barely survived, and “the iPhone13 and Pixel 3 were somewhere in between.”
The squad also took a close-up video of each phone’s speaker and showed them draining liquid. In short, the video works, but not necessarily perfectly. While it can remove the drips around the speaker, it has no effect on other break-in points like the USB port and SIM card slot.
No matter how perfect the video transmission works for you, it is better not to take your phone into the shower or with you while washing dishes, as the water resistance of the phone seals decreases over time.
