Apple Watch is reportedly facing difficulty in functioning for users with tattoos.
Colorful artwork and change in skin tone is affecting the light sensors on the back of the watch, which is affecting the performance of the next generation device.
Tattoos are interfering with the light-sensitive photodiode sensors which are used to detect the amount of blood flowing through the wrist, which is then used to calculate the wearer’s heart rate.
Apple said: "Permanent or temporary changes to your skin, such as some tattoos, can also impact heart rate sensor performance.
"The ink, pattern, and saturation of some tattoos can block light from the sensor, making it difficult to get reliable readings."
Early tattooed adopters of the watch are venting their frustrations via social media, with Twiter users even creating the hashtag #tattoogate to highlight the issue.
The problem reportedly extends to smartwatches and wearable fitness devices by other brands too, while some users with dark colored skin also experiencing problems with certain functions of their devices.
Apple watch was launched last month and comes in 38 variations with different bands, styles, and size.
