I have some questions regarding the LG G4.
1). Does it come with Marshmallow already installed or with Lollipop?
2). Is the speaker volume loud? I'd like to get this for my dad who has some trouble hearing. I have the HTC One M8 which is very loud, how would it compare in terms of volume? Sound quality?
3). Is it an overall good phone that will last? (I haven't been too impressed with LG in general in the past...)
