If you have recently considered whether you want to sunscreen this summer, I would like to advise you that if you want to buy an Apple Watch, you should have a good sunscreen, because the skin is too dark and Apple Watch will not work properly!
On April 29th, foreign media said that the first batch of users who started Apple Watch sent back feedback that the newly bought Apple Watch frequently suffered from sensor failure, and the heart rate, unlocking and other functions were not allowed or even could not work normally. I thought it was a problem with the quality of the product itself, but after several tests it was discovered that it was because the wrist tattoo or the skin was too dark to cause the Apple Watch function to malfunction... God, this is the legendary white cover, one Black and old? !
Come, let's take a look at the actual measurement.
First, let's take a look at the normal wrist (see below). The Apple Watch is very normal and accurate.
Then we look at the arm that has the tattoo (the same table)
Hey? Two steps, something went wrong.
