Sony Xperia Sleep/wake button

[jojobeans]

Hello,

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.

1. Does this happen randomly or all the time?

2. Restart the phone and see if you experience the same problem?

Just randomly. Like today it happened maybe twice, but before that it only happend about 2 during the week.

The problem could be an app but if it doesn't happen all the time, don't worry about it.
