A new firmware update is currently rolling out for the Sony Xperia M (C190X). Build version 15.1.C.1.17 fixes some of the reboot issues that plagued the handset when headphones were attached. The firmware is currently rolling out in Asia and certain parts in Europe such as Germany. We tried to look for the update on our UK SKU of the Xperia M but no update was picked up, so hopefully it will be released soon.
Thanks Colin!
