No longer recognized by computers

[cactusgecko]

My phone is all of the sudden not recognized by any computer. Can't even see it if I sech for new devices.

It's up to date, restarted, used different cables, tried both usb-connection modes.

Hi, Wake up the screen savers and unloke the screen saver if you have it lock.

You mention "computers" - do you mean you've tried with a few different computers?

Does the phone charge via USB?

If that's the case it might be something wrong with the USB socket on the phone and in that case you need to send in the phone to a service center for repair. Contact your local Xperia Support for more information:
