I am nearly 70 and not technically very wise, but was a happy LG GA 55 7900 user until the update last week to jellybean. The bugs noted and reported so far: 1. As others have reported, Flash is not supported so cannot now watch on-screen news videos 2. Browser has changed from PC desktop to Chrome mobile - cannot think why! It is 3 times slower and unstable. 3. Notification sound has all but disappeared it is so faint with no volume control in the software. It certainly cannot be heard with the TV sound on 4. Visual on-screen notifications have completely disappeared. The "New Email" visual on-screen banner notification with Aquamail no longer works so combined with # 3 above, the app is now useless. 5. Use of my Logitech usb keyboard is now very unstable I am sure I will find more in time. I had a long talk with LG support. They were sympathetic but said that all the bugs/problems I reported are "known" but all they could do was send bug reports and complaints from customers to Google and hope they fix it! I suggest you call LG support, and ask for an official bug complaint list to be forwared to Google and hope!
