Problems answering calls

[mrat93]

Since I got my iPhone on the 29th, I've the same repetitive problem trying to answer calls. The only way I can ever answer calls is if I have the headphones in and I use the built in controls. If I try to use the "Slide to Answer" function, the screen would not respond. Has anybody else been having this problem?

Just re-boot. Seems to clear that right up. Hold the screen lock button for several seconds, you will be prompted to power off. Wait a few seconds and power back up.
