calling

[yulka78]

I have my compact z1 for 5 months. Recently while on a call it starts calling random people from my contacts trying to merge calls and i cannot stop it once it starts calling during an ongoing call. Also the power/sleep button on the side is not responding unless i press it with force and for a long time then only offering power off optrion.
