My 55 UH7707 received an SW update to version 05.50.06. Here are the issues I have encountered:
1. The whole user interface became really slow.
2. Also, what is most annoying, application updates are not installed, for example, NETFLIX has been impossible to update, being stuck in vicious circle,asking me to update the app, and then not being able to complete the installation of the update.
3. Wired connection was disabled, ethernet module was not detecting a cable. I had to do a hard reset to enable the ethernet, and reacquire wired connection to the internet
