Default [Q] Is 4.4 now working normal with Spiegen Slim Amarour View?

Just got a notice for a 400+MB software upgrade.

I'm guessing that it is 4.4

Using the Spiegen Slim Armour View that I got about a month ago.

Is it still problematic?

Are there any other issues with 4.4 that would encourage me to stay with 4.3?
I haven't really heard of the great advantages of 4.4 other than having the latest.

Thanks
