My new Essential Ph 1 is freezing up or locking up and then it becomes a totally dead stick. Then I have to wait till it completely drains the battery and then I recharge it and then it comes back on. This has happened twice. Maybe its the Facebook app or Tumblr app. I don't know or maybe its the new Android program. All this started when I accepted the latest upload. I'm seriously considering going back to my old standard iPhone SE. It never gave me any of these annoying problems. I think I'm going to send this Essential Ph 1 back for full refund.
