Help How can I avoid the bootloop.

[LG G4 Bootloop]

I have a LG G4 H811 I've been hearing about the boot-loop issue. I would really like to know the best way to avoid the boot-loop issue so I could make the device last more than a year or two because it is a really good phone. My phone serial starts with 505 so it was made in May 2015. I bought mine from amazon back in 12-30-16.
