Samsung launched its beta testing for Android 6.0 Marshmallow, something that previously Korean company didn't do.
Owners of Galaxy S6 and S6 Edge Galaxy can take part in the tests, but there is one condition, they must be a citizen of South Korea.
Then to take part in the tests theres a requirement to send application using the app named Galaxy Care, which is available for customers of TK or LG U +.
We know nothing yet about extending beta tests to other countries, and for more information we have to wait patiently, we know only that the first Galaxy phones that will receive the update will be this year's flagship, and it will happen probably in January next year.
