Default LG G2 Modified Contacts

Guys, is there possibility to change Contacts apk? The fact is that Call button at Contacts apk is far from contacts icons. When you use only one hand, for example left hand, in order to call from Contacts you need to move and hold out your left hand's thumb to right side of Contacts. But if Call buttons were just near contacts icons, if would be much easier to make a call. Is it possible to do that? Please, just tell me how
