The iPhone XS and XS Max are not the only ones to be affected by bugs; the Apple Watch Series 4 is also affected.
Apple Watch Series 4: summer time bug
Indeed, the complications of the new Apple Watch Series 4 dials would be the cause of a bug related to summer time. Australian users have just experienced the time change and find that their watches are now stuck on a series of loop restarts.
The complication of activity on the dial Modular infographic draws a chronological graph of the current day, displaying hourly data for the calories burned, the minutes of exercise and the hours of activity that make up the activity circle. Although the exact problem has not yet been diagnosed, but it appears that the complication related to an important activity simply cannot manage the display of the graph due to the time change.
The watch restarts repeatedly as long as the dial Modular infographic is active with the Activity complication. Each time you start the Apple Watch, it tries to load the complications, it fails and then it restarts. This goes on and on until the watch runs out of battery. In order to resolve the issue, users must remove the dial Modular infographic via the Watch app available on the iPhone.
Obviously, Apple will need to release a watchOS 5 software update to fix this bug to prevent the problem from happening again. Most European countries change their time on the last Sunday of October; Apple has a few days to correct this.
