Samsung officially launched the Galaxy Beta Program a couple of weeks ago. The program allows registered members who get selected to try pre-release builds of Android 7.0 Nougat on their Galaxy S7 or Galaxy S7 Edge. This program only supports a handful of countries including the United States and spots quickly filled up when it was launched for the first time, however, Samsung now appears to be opening up the program to more members.
Multiple users over at the XDA forums have reported that they are able to register and get a spot in the Galaxy S7 Nougat beta program. Previously they would receive a notification informing them that the spots had been filled and that they may have to continue waiting.
Almost all of the reports have come in from the United Kingdom which suggests that the program may only have been opened up to more members from the United Kingdom. However, the possibility exists that Samsung might do the same for other markets that it supports in this program.
The process to sign up for a chance to be selected remains the same. The Galaxy Beta app has to be downloaded first prior to registering. Once users register, they have to wait to be selected and if they are, they will be notified and given details on how to install the beta firmware. They will then receive all subsequent beta releases over-the-air like normal software updates.
