Hi,
Like many of you, my TV has started lagging. Both in the initial menu and when we're streaming. There's also the 'Obtaining data' when we're watching TV on the antenna.
Here are some recommendations that I've seen reduce the lag a lot, yet to be verified in streaming, but at least in everything else it has greatly reduced it:
Activate developer options in settings. Settings->Device Preferences->Information->Build, click many times on build to activate developer options.
In developer options:
1. Set all animations to 0.5x (there are 3).
2. Force GPU rendering (enabled).
3. Maximum background processes (max 2).
In device preferences
1. Usage and diagnosis. Deactivated.
2. Google Assistant. Deactivated. (if you don't use it).
Install FLauncher. A much lighter launcher than Patchwall or Google TV.
Install ADBControl app on a computer and connect to the TV via its IP (Device Preferences->Information).
1. Disable Patchwall
2. Disable Android TV Home (CAREFUL, first install the FLauncher). Once Android TV Home is disabled, when you go to home with the remote button select Flauncher as default.
3. Disable the ones you don't use... in my case:
Amazon Alexa
Print Queue
Mi Wallpaper
Google Play Games
Mi Channel
Patchwall Update service
Xiaomi TV +
Youtube Music
...
To avoid the 'Obtaining data' message, what I've done is to install Mochi Live TV. An application that works with the antenna. It works somewhat better than the native one, and at least it doesn't show the 'Obtaining data'... I disabled Live TV after installing this.
