Download speeds on the iPhone or iPad can vary widely depending on the quality of your data connection. Whether your device is using cellular data or Wi-Fi, getting a measure of download and upload speeds is simple. It can be useful to know if you are getting the expected speeds or the actual Mbps that your service provider offers. When it comes to broadband, most providers charge more money for faster speeds.
Some Apple Watch owners are experiencing a problem where the screen goes blank and never comes back. The permanently blank screen issue has affected a small percentage of Apple Watch units manufactured between April and September 2021. Only Apple Watch Series 6 models in the 40mm size have displays that turn off and stay off due to this problem.
Apple Watch owners having firmware problems can now try recovering their wearable device directly from an iPhone. This wireless method, while not foolproof, can avoid a trip to Apple for service. If your Apple Watch freezes up, crashes during the update process, or stops working, it may prompt you to initiate a restore. To use this feature, the iPhone requires iOS 15.4 or later and the Apple Watch must be running watchOS 8.5 or later.
According to Apple Support:
Occasionally a buggy app or a new iOS update will result in instability that sometimes causes your iPhone to freeze or become otherwise unresponsive. Instances of this sort require you to force a reboot (aka hard reset, hard reboot, force restart, force reboot). A force reboot will retain your data, so it's not like doing a factory reset which erases everything. Hopefully after restarting you will be able to get rid of the offending app or revert to an earlier more stable version of iOS.
Some iPhone 13 owners have experienced a software bug that turns the screen pink. Not only this, but the problem can cause other issues such as frozen apps or sluggish performance. In some cases, Apple has reportedly offered replacement iPhones for affected customers.
