xperia P touchscreen issues whilst charging

[rumpel]

since the last update i faceing various problems with my XP.

got the gps error that some here mentioned already earlier this year, issues to connect BT heartrate monitors etc..

since yesterday I got a new one:

everytime I plug my cahrger in and charge the phone the Touchscreen is not working correctly.

its lagging 1-2sec. and you really have to push with some force to get reactions.

as soon as I deplug it, it reacts normal if plug again it lags again.

restartet the phone twice, without success.

additionaly my standby time went down from 1day+12hrs to only 16hrs .

I hope it is not hardware issue,but if the touchscreen makes trouble only when charging,it could be a voltage problem or the charger is damaged.Could you repair your phone with SUS or PCC?

What should I do?

Repair phone software with Sony update service or PC companion.But remember to back up before doing everything.You could also try another charger before repairing.
