iFixit has long been tearing apart our beloved devices to reveal how manufacturers thought up to puzzle-piece together every feature. In the end, the device is given a repairability score out of 10 (10 being the easiest to take apart and replace components). Their most recent teardown was for the LG G4, which scored an impressive 8 out of 10!
How did LG manage this? For one, the back cover and battery are easily removable without any tools, a capability that has been disappearing from modern devices. From there, they merely used a Phillips #0 screwdriver and a little prying to get access to the motherboard:

And once iFixit got down to the nitty-gritty (and took some really cool X-ray shots of tiny component mechanics!), they were fortunate to find that “Many components are modular and can be replaced independently.”  Be sure to hit up the source link below for more images and details.
To compare, the Samsung Galaxy S6 received a mediocre repairability score of 4 out of 10 and the HTC M9 barely made it out alive with a score of 2 out of 10. So there you go. If something breaks on your shiny new G4, you have a reason not to freak out so much.  Seriously, calm down.
