Hi
mccann1987!
When judging updates from posts on forums such as this, ensure that you are looking at the one's for your model and not some Snapdragon, carrier minority variant, whose firmware and update will be different from the one your Global model is receiving.
This latest update,
PD3, not only installs the Google April security patch to help protect your device but also has a whole host of bugfixes to address minor issues with the firmware. See,
Galaxy S7 and Galaxy S7 Edge updated with touch improvements. Therefore, it is highly recommended that you install the update as soon as possible.
No one on here will be able to guarantee that a particular update on someone else's phone will go smoothly since it could be an owners own user app that causes the problems.
If you wish to err on the side of caution, you should ensure that you have backed up your phone prior to updating, see,
Backup! Backup! Backup! NOW!.
After the update, you should wipe the phone's cache partition to clear out any detritus from your previous firmware as this causes the most update problems and complaints. See, video...
