Hi All: Although the #LGG4 is my primary phone due to its vastly superior camera, #tmobile pushed Android 6.01, Marshmallow, to the relatively old Samsung #GalaxyS5 I also happen to own. Not bad. Shuts down power draining and RAM using apps, lower control SW buttons now light up briefly and apps really are faster. Thanks T-Mobile. During the bacn and forth on twitter, T-Mobile was replying to tweets in record time! Wayne
