However this morning when I tried to make a phone call, the phone app opened briefly and then closed again. I tried the contacts app, which opened OK, but when I selected an entry it reported "Contacts closed".</P><P>The Support app was also Closed.</P><P>After I contacted the support web page (via my PC) I switched off the phone (hold down power button and 'Power off') and then switched it on again and this appears to have fixed the problem.</P><P>Is this a common situation? What is likely to have caused the problem?</P><P>The memory has approx. 9GB free.</P> Wed, 11 Feb 2015 11:23:43 GMT https://community.sony.de/t5/xperia-archive/contact-app-closed/m-p/3355945#M468771 Jeff-A 2015-02-11T11:23:43Z https://community.sony.de/t5/xperia-archive/contact-app-closed/m-p/3355946#M468772 <P>Just like any computerised device it has it's moments and a system restart fixes the issue - Could be a build up of cache blocking the memory from processing new commands which likely to be the issue and a restart clears this blockage</P> Wed, 11 Feb 2015 11:27:29 GMT https://community.sony.de/t5/xperia-archive/contact-app-closed/m-p/3355946#M468772 Thommo 2015-02-11T11:27:29Z
