Wife has just bought Experia E1 D2005. SHortly after getting it has just upgraded it to Android 4.4.2. The myExperia phone finder / ringer software does not appear in the Settings>Security device locator. Device administrator is switched on and location enabled. Is MyExperia not avilable for this device / android version ???
If you don't see it under settings then security, it might not be available in your region, contact your local Xperia Support
