Your Internet Connection is Unstable

Now, I'm a geek, and I'm the sort of person that loves to spend an afternoon with a relatives PC cleaning it up, defragging it, running anti-virus and installing spyware catchers, installing Windows patches, all that gubbins.  I know - I'm sad that way (even I think twice though when, after reinstalling Windows 7, having to install 120+ patches that Microsoft tells me are critical updates)
So this weekend when my Samsung Galaxy S3 told me that it had an update to install, I didn't hesitate.  I believe that it has now updated its software to Android 4.3 (Jelly Bean), and so far I've only really noticed one change.
It now criticises the quality of my internet connection.
Twice now it has flashed up a notification, stating "Your internet connection is unstable".  I'm not entirely sure what this does, apparently if its unstable you can set your phone to switch to mobile internet, but as I've nearly used my monthly internet allowance I'd rather it just not connect to the internet.  I did note that the second time it warned me about my unstable internet I had just walked out of the house - if it was really a smartphone it would have checked its integrated GPS and worked out that my wi-fi wasn't unstable, rather it was that the phone was moving away from the router (yes, it was towards a takeaway if you must know)
I mean, I know I've had problems with my internet in the past, but is this a new feature?  Smartphones with opinions?
What if they continue in this manner?  Can you imagine the notifications?
I'm sleepy. Turn me off so I can install some updates.

I'm hungry and need recharging.  Plug me in.

Or even...

I'm aroused. Take a firm hold of that micro-USB cable and PLUG. ME. IN.

I'm scared.
Merry Christmas by the way!
