Well, decided to bite the bullet and just upgrade to see how it was. So far, not bad, but the WiFi sync bug has hit me. I use a 3rd party app called MailDroid. I can sync just fine with yahoo mail and my ISP provider (via POP3).
On my home network, it won't work unless I'm on LTE. Might be an IPV6 issue. I'll have to dig into the settings later when I have time to see where I can turn this off in my router. I thought I had, but maybe I didn't.
At work, the WiFi seems to be fine with MailDroid. At other WiFi hotspots, it didn't work either. Again, could be the IPV6 issue.
5.1 LP apparently fixes this issue, but not sure when that will be released, if at all. I have heard from other people that LG/Verizon know of this bug and will issue a patch to fix it. Whether that bumps us up to 5.1 or is just a quick fix that keeps us on 5.0.1 (5.0.2 still has the memory leak), let's hope they fix the WiFi and memory leak for this phone.
Otherwise, appears to be working pretty well. Battery life is about the same (I did a FDR before the update) and it seems to be the same.
