Overall performance wise all of them are great phones but I like my OnePlus 3T more coz of its powerful performance snapdragon 821 processor. Moreover, cameras,display,battery are also good. However, for selfie centric people Oppo F3 Plus is a good option. My friend has this phone and dual selfie camera captures great selfies. Oppo F3 Plus vs Samsung Galaxy C9 Pro vs OnePlus 3T
Hanging problem ? I am not facing any such issues. Try to update it to lastest available OS update and check if you have installed any buggy app which runs in the background. I had installed some app in past from different website rather than playstore. After that I was facing slower performance but when I uninstalled it then it started working smooth again.
Friend one plus 3 and one plus 3t Both Is best phone but if you see Prossesor in one plus 3 you got Snap 820 and in one Plus 3t snap 821 my suggestion is this you have to wait for 10 days because their are new oneplus 5 was launching and in that you got Very powerfull Prossesor Snap 835 my suggestion is that you have to wait for oneplus 5
personally I like Apple IPhone 7 so would suggest for it ,is definitely a beauty worth beholding,owered by the most powerful processor so far and the latest iOS, the smartphone indeed solves your tasks in a jiffy. Apple IPhone 7 vs OnePlus 3T
