Apple pulled back the update of its WatchOS 1.5

Apart from smartphones and iPads, Apple produced its watchOS 5.1 which is lightweight, delicate and waterproof. When the watch released, some users stated that the company suspended the update of Apple Watches. When the watch was updated, the Apple logo got stuck on the watch screen. And rebooting the paired smartphone and watch would not sort out the problem. Many customers complained the watch was not durable which left in an endless reboot process.
One user tweeted about WatchOS 1.5:

My Apple Watch yesterday was bricked by the new watchOS update. Brought it to the Apple Store and the geniuses couldn’t figure out a solution. No stock in store (popular) so they had to send it out for repair. Now it looks like it was a widespread issue. https://t.co/3TmEG1qcXe

You can see from the tweet above that the user was not satisfied with the watch he bought. He stated that the durability was short and sent his watch to the repair stores. They stated it would be shipped for the repair.
Despite its lack of function, the watchOS 5.1 contained new emojis and group FaceTime audio. The bug is affecting series 4 watches.
It is not clear when the watches will be reconstructed and what are the problems behind this. The company pulled back the 5.1 updates as well as the series four watches. So if you own this watch and experienced this problem; it is advisable not to install it, and if you need the watch to be updated, please contact the nearest Apple support service to resolve the issue.
According to CNET, the company issued the statement:

”Due to a small number of Apple Watch customers experiencing an issue while installing watchOS 5.1 today, we’ve pulled back the software update as a precaution. Any customers impacted should contact AppleCare, but no action is required if the update installed successfully. We are working on a fix for an upcoming software update.”

There is no exact deadline as to when the updated version will launch. If it had come out, the watch would be called watchOS 5.1.1. At the moment there is no real solution to this problem, but rumor has it Apple will suspend the update for now and release it sometime later. However, this solution would not affect such a huge amount of users. It would still be an issue as it plaques to every other version of watchOS.
The previous version watch series 4 has the ECG (electrocardiography) support. The company promised this feature would be available in an upcoming software update. However, this feature is not found in watchOS 1.5.
Other users complained about their new watches and were dissatisfied.
