The first major update for the Samsung Galaxy S7 and S7 edge is now rolling out in the UK — and it's a big one.

An over-the-air update going out today brings a number of changes and fixes for British Galaxy S7 owners. The update, which has been appearing in other parts of the world for the past week, has landed this morning on unlocked UK versions of the phones. The new firmware versions — G930FXXU1APD3 and G935FXXU1APD3 — include tweaks to the touchscreen software to help avoid unintentional taps on the edges of the S7 edge, while also eliminating phantom touch events sometimes caused by scrolling.

The Galaxy S7 maintains its track record for speedy Android security updates.

Alongside these Samsung-specific fixes, today's update brings British GS7s up to the April 2, 2016 Android security patch, putting Samsung's flagships less than two weeks behind Google's Nexus devices in terms of security fixes.

And interestingly, although it's not advertised on the carrier's website or in the firmware's changelog, the new update enables support for EE's Wi-Fi calling. Upon updating, the option is automatically enabled under Settings > Wi-Fi Calling in the Phone app, and we received an automated text from the carrier within a few minutes of updating. This is a big deal because until now only EE-branded versions of Android phones have officially supported the operator's Wi-Fi calling features.

If you're running an unlocked, unbranded UK version of the Galaxy S7 or S7 edge, hit Settings > About device > Download updates manually to see if your update is ready. Network-branded GS7s will, as ever, likely take a little longer to receive the updated firmware.
