If you experience that the device runs very slow when, for example, entering menus or opening applications, read on to get suggestions on how to solve the problem. Verify after each suggestion whether the problem was solved, before trying the next one.
Wait for two days to see if the performance improves
When you have performed an Android system update, it may take up to two days for the device software to stabilise. Some processes initiated by the update will continue running in the background for some time, for example:
- The indexing of files.
- The updating of pre-installed apps. The apps are updated when the device is turned on and connected to the Internet for the first time after the update.
The processes running in the background are using the processor a lot, causing the device to be temporarily perceived as slow for a day or two. This behaviour is normal during indexing and app updates.
Restart the device
If the device is still slow two days after the update, restart the device to see if the performance improves.
Perform a factory data reset
Back up any important data saved on the internal memory of your device, and then perform a software repair using Xperia Companion. Note! A factory data reset will erase all data on the internal memory. You can backup using Xperia Companion. Content on an SD card will not be deleted.
Format your memory card (SD card)
Try formatting the memory card. Formatting the card removes all files and folders including any leftover data and corrupted files. Note! Back up any important data before formatting the memory card. You can use Xperia Companion to move the memory card content to a computer.
