I don't think there is a problem. Maybe a restart can help.

Maybe @Samuel has an idea. Sometimes the sound doesn't fully play when I connect my Z1 to charger but I don't see a problem.

Why do you need it? The service is active without the icon.

because...when the NFC icon shown on statbar.........my divice lookes more beautiful...

1 more q: is my device is unlock.......how i check this...?

[_alexdon_]

Unlocked from any network? Did you buy it from a carrier or SIM free (from a retailer)?

You can also check by dialing *#*#7378423#*#*- Service info - SIM lock and post the results.

oo yes my device is unlock and bootloader also......

but what is bootloader ? and how it work ?

[_alexdon_]

Don't mind bootloader for now,if bootloader allows unlocking you can flash custom ROMs on your device.

So your device is SIM free?
