Reminders Does Not Sync
Description: When you use Reminders on one device and then open the same list on another device, it is not in sync. Leaving Reminders open or closing/opening the app does not force it to sync. This happens quite frequently — about 50% of the time.
Workaround: Turn off Wi-Fi and use your 3G/4G Network. Open Reminders and the list will sync. If you have an iPad without a data plan, try toggling Wi-Fi off and then on, then open Reminders. If neither of these methods work, try restarting your iPhone, then launch Reminders. You can also use an alternate “to do list” app such as Clear.
Description: Occasionally, when using Reminders, the app will freeze. This occurs intermittently after editing the list and tapping “Done”. Sometimes Reminders will freeze even when not in edit mode. Freezes are infrequent. They happen about once every 20 times the app is used.
Workaround: Waiting will usually work. After less than one minute, the app will become usable again. Tap the home button twice (or swipe four fingers up on the iPad) to launch the multitasking view, then relaunch Reminders.
iMessages Not Sending
Description: The popular iOS iMessage system is having problems after the iOS 7 release. Sometimes when a user sends a message, it appears to be sent. Later, the message shows up undelivered with a red exclamation point next to it. This issue affects only a fraction of iMessage users, according to Apple.
Workaround: Restarting the device will usually fix the problem. If not, try resetting Network Settings (General > Reset > Reset Network Settings).
Status: Fixed in iOS 7.0.3
Blue Screen Crash
Description: iOS 7 has a bug which will make Windows users feel right at home: the Blue Screen of Death (BSOD). I have not experienced this issue at all. In fact, I have never had an iOS device completely crash on me. Nonetheless, users are reporting that, particularly when using iWorks, their device will crash and show a blank blue screen. The device then restarts automatically. Unlike the Windows version, there are no details presented. This does not mean they don’t exist. To find the details and stack trace of any app crash, simply go to Settings > General > About > Diagnostics & Usage > Diagnostics & Usage Data. This will display a list of all crashes. By tapping on an item, you can see the details. You can also automatically send this data to Apple, which is turned off by default. Sending this data will help Apple fix these bugs, but it will use network bandwidth.
Workaround: Users report that turning off iCloud sync for iWorks apps will reduce blue screen crashes.
Status: Fixed in iOS 7.0.3
