My device freezes or applications suddenly shut down
Downloaded applications can cause your device to behave unexpectedly or affect its
performance.
Use safe mode to check if any downloaded applications are causing the problem.
In safe mode, your device only starts with software and applications that were already installed
when you purchased your device. If the device’s performance improves in safe mode it’s likely
that one or more of your post-purchase downloaded applications are affecting the device
negatively. You can exit safe mode and restart the device to uninstall the application or
applications that you suspect are causing the problem. If the problem is recent and you're not
sure which application is causing the problem, you can start by uninstalling the most recently
downloaded application.
