Restarting And Resetting Your Device - Sony Xperia T2 Ultra dual User Manual

Restarting and resetting your device

You can force your device to restart or shut down in situations where it stops responding
or won't restart normally. No settings or personal data get deleted.
You can also reset your device to its original factory settings, with or without deleting
some of your personal data, such as music and pictures. This action is sometimes
necessary if your device stops functioning properly, but note that if you want to keep any
important data, you have to first back up this data to a memory card or other non-
internal memory. For more information, see
page 129 .
If your device fails to power on or you want to reset your device's software, you can use
PC Companion or Bridge for Mac to repair your device. For more information on using
PC Companion or Bridge for Mac, see
Your device may fail to restart if the battery level is low. Connect your device to a charger and
try restarting again.
