Default [Q] Removing swipe to unlock, because phone is freezing?

I have big irritable problem. Touch on my phone get freeze for few seconds while im trying to unlock it. When someone is calling me and I need to swipe it to answer, it get freeze too, and only if im lucky I answer on that call. I have installed app No Lock but stil when you press any button, touch still get freeze on 20-30 seconds. Can it be fixed somehow? Is there any way to completely move that swiping from system?

Maybe my English is not good, but I hope you can help me
