So I have a Sony Bravia (kd-65ag8) with Android Tv 9 (kernel 4.9.225) and I hate it. It is so slow. Even changing volume lags. The system just struggle to give me useless recommendations on a cheesy home page. Had to limit the system to one process. Amazon prime video just restart itself when I shut it down so I have to reboot the tv every fucking time. What am I missing ???
Built in tv software is usually trash. Get a streaming box, Shield, appletv, fire tv, Roku etc… and you will be happier than with the built in software.
I have the exact same TV, and it runs fast and smooth almost all the time. Only very rarely, if I have just exited an app, it stutters 0,5 seconds. Sounds like another app is working the TV hard in the background. Is it ok directly after a reboot?
Try a factory reset.
Start by checking if there is an update available.
I just bought an Apple TV because I have come to hate my Sony X900F Android TV. I dislike the interface of Android TV and since I moved this past week, I decided a change was in order. Apple TV takes a bit to grow on you, but at least the interface is responsive.
Factory reset is your best bet now. Also check if some app is trying to update itself in the Google play store. That turned my android tv device to a snail.
Go to app store and download background apps and processes list application. Run that and close everything that shows as running and clear cache on each app. Before you close and back out of this tool click on the system user tab. On the 1st click it will take you to all the system apps. Don't change anything here, just click the tab again to go into the user app screen. You will now hopefully see a clear screen with nothing running. If there is something running, close, clear cache and exit out. Reboot and test. Might help, might not but well worth a try. I use this on my nvidia shield which runs flawlessly 99.9% of the time and this solves any slow response
