It's the factory TouchWiz rom and yes it was a fresh 4.4 kk install and I did root it could it be the host file? Cause I did another fresh install and all the apps work fine now except Google play store I've tried uninstalling it and then downloading the new version and putting it in system/apps giving full permissions for install then restarting my phone and nothing seems to be working. I did mess with the host file awhile ago but I did a fresh install again.
I don't see what a host file would have to do with all of your apps crashing, but then again doing a full wipe and reinstall should fix it if it was something you did with a file. Maybe you have a bad image? Could always just try going to your recovery doing a full wipe without reflashing and see if that fixes anything. Is the play store just force closing or what?
