Very user friendly
No issues with this TV from purchase 6 months ago. UI is very user friendly and responsive. The remote keyboard can be improved as it is difficult to type words/ phrases.

I like my new LG Smart TV
Very nice 4K TV! I like it! I wish the desktop TV stand could be raised by at least 200mm, like a PC monitor.
Unable to access some of the built in app, for example Tennistv app after registration online.
Google Assistant and Alexa both NOT available in Hong Kong! How come?
