Arena people skipping across screen

I've finally able to get on ew3 after problem switching off my old defective note 3. Then 2.3 comes out now only in arenas it's impossible really to fight people. I do my attacks and they are not where they are really on my screen but all their attacks hit me where it shows them coming from direction. I shoot for example west and really they are on east side coming at me. What is going on and I know it's not my network connection, I've never had this problem before and only in arena. I can't really do arenas if the players are not really there where it shows me and only shows me there real position when there attack hits me.
