Charging Problem. :-/

[Khairul Roslam]

Hi. I'm new member and also new user of Android 4.4.2 (Kit Kat). My phone type is Samsung Galaxy SII (GT-I9100). The problem is when I'm charging, it's hard for me to touch. Almost 90% doesn't move when I try to slide. So lag. When I removed the charger, it's been smooth as usual. Why is this problem occur? Can help me?
