Hi All,
I just got and activated my new phone. The wonderful LG G2. I am upgrading from the Galaxy Nexus. I am glad I was able to extend my contract and keep my unlimited data. That was the key,
Now since I have the LG G2 can someone direct me to what I should do first? I saw there were themes available, any idea on where to get those? Any suggestions on cases? Any tips and tricks? Thanks all.
Enjoy your new smart-phone! I can tell you that you just got the best device in the market

(Go LG G2!!)
First of all, I would definitely recommend keeping the original theme, as I find that to be the prettiest, but I also think the one with the red building in the background is nice. All of these are default wallpapers, and I think they're the best. In case you didn't mean wallpapers but you meant themes, there is a theme called Marshmallow which is pretty funny, but I like the default one better.
About cases, I have the "S" style protective case and it's very good both in protecting the phone and being very slim. Though if you want some heavy-duty stuff you could go for the Otter Box.
About tips and tricks- First of all, you can't miss the double-tap. I found that to be a really useful feature, and I use it a ton. Also, since you have the Verizon-variant, that means you have wireless-charging enabled, so I would recommend buying a wireless charger.
I wouldn't turn on the smart screen, since I didn't find it to be working well.
A very big tip I would recommend charging the phone until 100% and then let it fall to 0%, I found that fixed some battery issues I had at the beginning.
You have a great new phone, enjoy it!!!
