Apple has released a new update to the watchOS, fixing bricking issues in Apple Watch that made the device unusable after users attempted to install the previous update.

The new watchOS 5.1.1 comes with over 70 new emojis released with iOS 12.1, new full-screen colour watch-faces and support for group FaceTime audio for up to 32 people, The Verge reported on Monday.

The previous update — watchOS 5.1 — that was released last week, was pulled out quickly after users reported that the update caused issues to the Apple Watch during the installation of the update.

“Apple Watch owners can rest assured that today’s update is specifically built not to brick their devices,” the report added.

Since Apple’s smart-watch does not plug into a computer, affected users had no options other than calling Apple support and wait for the company to replace their device.

The issue, however, seems limited to the brand new Apple Watch Series 4 devices.

Previously, a bug that was discovered in Apple Watch Series 4 was causing the device to crash and get stuck on re-boot loops, the media had reported.

Apple Watch Can Detect And Notify Users Irregular Heart Rhythms

The results of the Apple Heart Study highlight the role that innovative digital technology can play in creating more predictive and preventive health care," said Lloyd Minor of the Stanford School of Medicine.

Apple Watch can detect and notify users when they experience irregular heart rhythms, finds a study demonstrating the ability of wearable technology to detect atrial fibrillation.

In 2017, Apple had partnered with researchers from the Stanford University and launched an app called “Apple Heart Study” to determine whether a mobile app that uses data from a heart rate pulse sensor on the Apple Watch can identify atrial fibrillation.

Atrial fibrillation, a deadly and often undiagnosed condition, can lead to strokes. The condition often remains hidden because many people do not experience symptoms.

The findings showed only 0.5 per cent participants received irregular pulse notifications, an important finding given the concerns about potential over-notification.

Eighty-four per cent of the time participants who received irregular pulse notifications were found to be in atrial fibrillation at the time of the notification and 34 per cent who followed up by using an ECG patch over a week later were found to have atrial fibrillation.

“The results of the Apple Heart Study highlight the role that innovative digital technology can play in creating more predictive and preventive health care,” said Lloyd Minor of the Stanford School of Medicine.

“The performance and accuracy we observed in this study provides important information as we seek to understand the potential impact of wearable technology on the health system,” noted Marco Perez, Associate Professor of cardiovascular medicine at Stanford. Pixabay

“Atrial fibrillation is just the beginning, as this study opens the door to further research into wearable technologies and how they might be used to prevent disease before it strikes — a key goal of precision health,” Minor said.
