Considering Switching from Galaxy S4 to LG G4 and I have some questions

First off, Hi and I'm considering updating to the G4 for the following reasons:

1: Only camera that supports RAW shooting and Manual camera
2: MicroSD card is still an option.
3: I can swap batteries when needed.

I'm getting the phone from Costco and expect it will come with the latest update (612a I think) but I can't be sure till I get the phone. How tough is this phone to root? I'm not interested in custom ROMS or unlocked bootloaders, just want root for Adblocker, TI Backup, and debloating. Looks like I have to keep the VZW app running for advanced calling, so that is no big deal.

What are some problems with the phone. I've noticed touchscreen issues that seem to be fixed with the latest update, anything else I need to be aware of?

How is the battery life in real world usage? Will I get a day out of it Surfing, answering calls/emails, streaming video on occasion?

Should I stick wit VZW or jump to AT&T? My contract is up and I'm losing my unlimited data, so there is no reason to stick with VZW anymore. Is AT&T any better or worse than Verizon?

Thanks for any assistance.

Phone keeps switching to Power Save Mode

I have no rules set for switching into power save modes, yet I keep finding my phone in power save mode with all the radios turned off. I'm using a case with a viewing window if that means anything. Anyone else having this issue?

Thinking of switching from Note 2 to G4

The primary reason I'm considering the G4 instead of any of the new Samsung models is to gain root. If I order the G4 now and it comes with 12a will I be able to root the phone right away?

Thanks,

Switching Note 5 and Note 4 spens....

I like the clicky part of the Note 5 spen, so my question is can you store and use the Note 5 spen in the Note 4. Are they the same size? Wondering if someone has already done this without causing damage to either the phones or pens. Thanks.
