LG has always bucked the trend when it came to certain features that its peers were seemingly throwing away. Particularly, it has stuck to replaceable batteries and microSD cards even when almost everyone else turned away from them. In that area, the LG G5 isn't that different, but the Korean manufacturer did one better. It took modularity to heart and implemented it in the very core of its flagship. The end result is probably one of the easiest high end, premium flagship to tear down and repair.
