The pre-installed software on TV allowed all Smart functions to work. picture below shows software version 1115.5 where all functions were working! every update after lost most the functions available with Alexa. ie. power on/off, switch hdmi, view security cameras
i purchased this model because it allowed me to view my security cameras and switch them through the voice command of Alexa. The 1st software update i did 1 month after having the tv ALL of those commands stop working. And each update that has followed it still doesn't work!!!
Not to mention with each new update comes more LAG in every function of the TV.
