so far, I have a few issues with ics 4.0.3, but otherwise my main apps seem to be working.
I use my tab primarily for work, and I noticed that the keyboard that I use has somehow slowed down.... what I mean is that as I type, there is sometimes a lag of a few characters, and then all of a sudden they appear.
other than that, I noticed that some of the graphics on some games I play don't display correctly, for example Galaxy on Fire 2, the smoke looks like big squares instead of being smoke...
and in Epic Defence: the Elements, the graphics that were at the bottom of the towers when you choose to upgrade them, has disappeared completely. before it was partially visible in hc3.2.1
shazam no longer works, my flash light widget doesn't work (another app does tho), and some other apps miss behave....
that's all so far.
