I have a 77" S90CD that is quite buggy. The other week, I installed the latest firmware (1402) but still having issues. I noticed Samsung Download center pulled that version, and now only shows version 1310.3. The problem is, I cannot install that version via USB, as the TV states I already have the latest version (no downgrade possible). Hoping to get the latest stable firmware version to fix the bugs I am having.
Bugs include: audio sync delay, slow/sluggish UI, choppy motion when picture changes scenes, apps freezing during use.
