My Verizon Note 4 has gone weird on me. It won't reboot unless I pull the battery, leave it out for 45 minutes and then reboot. It locks up for a minute or so when in use. I'm assuming it's hardware. So I bought a replacement. It's still got a locked boot loader and is running stock 5.1.1 with the usual Verizon/Samsung bloat. I don't know if I want to go through the work of unlocking the bootloader, and then rooting and installing TWRP. I am not someone who swaps out different ROMS every week. I do like having a custom restore and Titanium back up. I load my phone up with a lot of apps and have a 128GB sd memory card that I can use for storage and to run apps off if I install link2SD (it was a pain to set up, when I did it on my current note 4). I'd like to hear some opinions. Root? Leave it alone at 5.1.1, don't root but take the Verizon update to 6.0.1? I'm stuck trying to figure it out, so any ideas will be welcome.
