https://community.sony.dk/t5/c-series/sony-xperia-sleep-wake-button/m-p/3439391#M4222 <P>Hello,</P><P>I recently received my c4 and have noticed that occasionally when press the slee/wake button, the phone's screen is on, but there is nothing displayed. I then have to press the button a couple more times to take me to the lock screen. Do you guys think this is a serious problem? Thanks.</P> Mon, 15 Feb 2016 04:32:56 GMT jojobeans 2016-02-15T04:32:56Z https://community.sony.dk/t5/c-series/sony-xperia-sleep-wake-button/m-p/3439391#M4222 <P>Hello,</P><P>I recently received my c4 and have noticed that occasionally when press the slee/wake button, the phone's screen is on, but there is nothing displayed.

Does this happen randomly or all the time?<BR /><BR />2. Restart the phone and see if you experience the same problem?
