I and many others had to buy battery draining. phone heating up and like I said apps not working. updating to lollipop was the best thing I did. and theres many note 3 users who are on lollipop with no problrms like me. but everyone has there own personal Choice. and now note 3 should get 5.1.1 which is good. Note 3 is an asm phone but now a days I am having a problem that it’s data connection and wifi are turned on automatically.
