Pc companion update failed

Is the message I get, when I start up Pc companion.

Done by wifi, with or without phone connected to Pc.

What to do, tried several times

Many times, when phone rings, phone turns black

Sony PC Companion has very low download speed like update via Wifi. try Sony Update service that is better than other ways
