Android 7.0 Nougat might be available on the Samsung Galaxy S7 next week. Based on a leaked screenshot, the software has a January 17 roll out date. The text in the image has been translated from Turkish to Spanish and it contradicts some prior reports. Samsung was said to be skipping Android 7.0 for Android 7.1. This leak should certainly be taken with some skepticism.
Even if the report is accurate, January 17 will only be when the roll out begins. It could take a bit longer for all Galaxy S7 (Edge) units to receive the software.
Samsung has been testing the Nougat update for months.
