I had pushbullet installed and on when this bug popped up out of nowhere last night two days after I installed the Verizon update. I started messing with settings and the phone froze to the point I had to pull the battery and do a factory reset. Nothing else got my phone to work. I also had greenify installed previously but hadn't used it yet. After the reset I loaded all my apps up except greenify and pushbullet and the phone seems fine. When I checked under services in Accessibility, nothing is listed now but I remember pushbullet was there previously. After reading everyone's posts I turned S voice off and on and the calculator is fine. I did not actually use s-voice yet. Going to stick with google to avoid this issue.
Not sure if it's related but another bug popped up this morning. Took phone off charger, noticed it was beeping at intervals of about 10 seconds, drove me crazy, saw that there were no notifications and oddly enough, it said the phone was charging when it wasn't. Then I watched my battery drain very fast with no services running. I didn't get a screen shot but the battery status screen showed the green charging bar in a series of blips probably corresponding to the intermittent beeps all this off the charger! I did a full memory cache wipe, rebooted, and it was fine. There was no way in hell I was doing Factory reset again twice in 24 hours. Been using phone all day with no beeping and battery drain seems normal. Anyone else seen or heard of this with Touchwiz or Note 4?
