A friend of mine has the following problem with his Note 3 (completely stock).
Since the latest 4.4.2 OTA update, sometimes suddenly the screen does not respond to touching it with your hand. It does react to the stylus.
Locking and unlocking the screen does the job, but only for a few minutes.
I wiped the phone via stock recovery, but the problem persists.
Anyone with the same problem, or maybe a clue?
