I removed the battery after 15 seconds once I noticed that and then put the battery back in but that doesn't work.. Removed it again and it has sat idle for 5 hours.. I'm so afraid of Lollipop as every update for last 6yrs as ruined my phone not to mention I suffered for 3 years with a phone that Motorola/Verizon and Google never fixed any bugs.. i just got Note 4 two months ago.. I've been so careful not to update.. Verizon says its Samsung forcing it on and you will automatically have to upgrade at some point.. Sad as I don't live life in fear but only fun..
