The device does not recognise my
wired headset
•
Make sure the wired headset that you are using
complies to the CTIA standard. Your device supports
the CTIA standard, and may not be fully compatible
with other standards such as OMTP.
•
If you have a wireless headset that is compatible with
your device, try using that instead.
My battery runs out quickly
The following tips can help you improve battery life:
•
Use STAMINA mode to minimise battery
consumption when the screen is inactive.
•
Disable all data connections over mobile networks
to save power when you're not using the Internet.
Doing so does not prevent your device from
transmitting data over other wireless networks.
•
Turn off GPS, Bluetooth® and Wi-Fi® connections
when you don't need these features.
•
Lower the screen brightness level or turn off X-
Reality for mobile.
