Google’s Android operating system has been welcomed and adapted by so many third-party manufacturers that it has all but become the benchmark, outmuscling market share from Apple in smartphone and tablet categories in the process.

Now, with wearables, the new category anticipated to grow quickly, Google’s top executive is rankled at what appears to be Samsung’s attempts to sell devices with proprietary Tizen software, essentially weaning off dependence on Android.

Reports have surfaced indicating that Google CEO Larry Page and Samsung chairman Jay Y. Lee didn’t exactly see eye-to-eye at a private meeting last week.

TechRadar suggests Page may have even ‘confronted’ Lee over Samsung’s plans to ship its Gear 2, Gear 2 Neo and Gear Fit wearables with Tizen software – not Google’s Android Wear. The website The Information initially posted about the meeting, which happened at the Allen & Co. conference in Sun Valley, after speaking with three people who were briefed on the conversation.

If the meeting was characterized accurately, the conventional thinking would be that Google is concerned about Samsung – one of its major partners – in fact becoming a competitor. TechRadar reports that Page tried to sell his position to Lee, however, by arguing that Android Wear is compatible “with a greater range of Android devices” than Tizen.

The Google-Samsung skirmish has precedent. While Samsung’s flagship Galaxy smartphone and tablet line all run Android and have sold well worldwide, reports suggest Google was not happy with Samsung’s heavy customization of Android and apps it developed for it. Of course, that’s ironic because Android’s origin as open-source, developer-friendly software is well-documented.

The Daily Digest News previously reported that Google had a 61 percent share of the smartwatch market in 2013. The Mountain View company will face stiff competition from not only Samsung and its Galaxy Gear line, but HTC, which announced the One Wear smartwatch, and Apple, which is expected to join the fray with a rumored iWatch in the works.
