I just went to check for mine (manually) and it was there, but SIGNIFICANTLY larger, 330.4MB. I'll repost after the update is installed. EDIT: Installed, cache wipe (after EVERY security update, just smart decision making). No visible errors/issues. Can't really speak to faster/slower. Note 4 has always been a hardware beast. Maybe a little snappier, but that could just be the cache wipe.
I just checked for the update. I got it.
Its 161.53MB for me.
1. Performance of games has improved.
2. Overall Device performance improvements.
3.Security update
I got it yesterday. Mine was also 161.53mb. My battery life seems a little better (by about an hour or so). I also noticed that autodimming now works when it's supposed to instead of randomly.
On my S7, it looks like this update fixes the always-tiny font size bug introduced in Messages with last months update. Now under Messages > More > Font size you can "Use device font sizes" or you can turn that off and use a font size slider, which actually works.
