Earlier this month, LG announced that they would open up a store that would be unique to the LG G5 and give developers a place to sell their modules as well as "Friends" for the LG G5. As of today, that store is open and located at lgfriends.com. Now LG hasn't mentioned whether this will work with future LG smartphones, but given the fact that they are setting up a store for this, it's very likely that future flagships will also be modular. Right now, the store is pretty bare, only showcasing LG's own modules and products. This includes the LG Cam Plus, the HiFi Plus from B&O Play, LG 360 VR, LG 360 Cam, Rolling Bot, and the LG Tone Platinum headphones.
Last week, LG held their developer conference in San Francisco, where they talked about their SDK and HDK for creating modules for the new LG G5. They have opened it up to developers, so we may see some new modules hit the store soon. Although it'll be a tough market, at least for now, considering there's only one smartphone that works with these modules, which translates to a relatively small market. The battery and charging cradle are not yet available on the site, but we'll likely see them appear soon.
The LG G5 is a modular smartphone – and that's where these "Friends" come into play. It's LG's latest flagship and the first modular smartphone to be openly available. It's not as modular as the Project Ara that Google has been working on for quite a few years now, but it is a start. Perhaps the best module available for the LG G5 – and it's not even coming to the US – is the HiFi Plus from Bang & Olufsen. For those that are serious about their audio, this is one module you will definitely want to pick up. The LG Cam Plus is another good one, as it adds a grip to the phone and some physical controls to the camera. Making it feel a bit more natural. Some of these modules are available at carrier stores, at least here in the US. And the LG Friends website does show you exactly where they are, so you can pick them up.
