My Note 4 Freezes A Lot topic

i am so annoyed with my note 4. it constantly freezes during phone calls. like i will be talking and then suddenly i can't hear them and they can't hear me. i end the call but it doesn't go away. there will be a small box floating in the top left corner of the screen that says the call is still ongoing and the only way to get rid of the box is to reboot the phone. after a reboot the phone calls will work fine for a limited time then back to the same thing. also some of the games i play will freeze up randomly and will require a reboot of the phone. i am completely stock and unrooted and ready to throw this thing out the damn window! never had any problems on my note 3. i get good bars in my house and never use wifi calling because that's even worse. anyone else have this issue?
