Samsung is continuing to proactively roll out security updates to its phones, with Orange's Galaxy S7 edge picking up the June security patch. As of now, the update is live in Spain, but it should be making its way to other regions and handsets shortly.
The manufacturer rolled out the May security update to the Galaxy Note 4 ahead of time as well. If you're rocking the Galaxy S7 edge, now would be a good time to check if the June security patch is available on your handset. As for what's fixed in the monthly patch, we'll have to wait for Google to announce its list of changes later this week.
