Can I change the call screen in Lumia? Lumia 535 has a touch issue and therefore I miss many call trying to swipe up before saying "answer or ignore". Is there a way that I can avoid this swipe up screen and straight away go to "answer or ignore screen"? Please advice.

as I can't comment... this touch issue can be fully solved only by hardware fix, they erleased few "final" fixes, every one helped a bit and upgrading to update 2 not released officialy made touch almost fine, but never solved problems completely. For me touch sometimes just declines to work if device gets too hot due to stress and/or charging, moisture also breaks a lot and unfortunately cold too
