    I just updated to 5.1.1 note 4 and rooted it and this problem occurred. I already did a factory reset and this problem still occurs. I'll be texting or on the Web and the screen will lag then lock. I already wiped cache.. What may be the problem.. Note 4 sprint 5.1.1

    Hi, this issue is common after the 5.1.1 update, and it seems to be mostly a SPRINT thing. What solved it for me was using Pattern Lock instead of FP scanner to unlock my screen, and I have been Golden since then.

    Same here, on Unlocked TMobile, Note 4, running 5.1.1. Love the FP technology, guess I'll have to do without it till a fix is released.

    turn off smart lock. That is what I found that fixes the lag/lock problem.
