According to Cnet, next Nexus Device would be manufactured by LG. The first Nexus was by HTC, and the following two Nexus devices were by Samsung and now may be LG. Samsung has had the most success thus far, following up the Nexus with their hot Galaxy Nexus, and with the phone’s success LG will have to work hard to warrant a break in Samsung and Google‘s relationship.
Anything could happen and Google has said it doesn’t want any specific manufacturer to feel like it’s the “preferred” Android phone maker. So we’ll see what happens.
