Install Nova Launcher and open the app drawer. Navigate to Nova Settings > App & widget drawers > Hide Apps. Select the apps you want to hide, and they won't show up on your app tray anymore. To reveal an app again, simply return to the same menu and uncheck the desired app.
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
