I bought my first smart TV ever a year ago now, which was a TCL Percee 55" with AndroidTV. Anyway, figured I should warn everyone from ever considering the same.
I have never had a consumer product this riddled with bugs before. Holy shit. I thought I'd be safe since after all it runs AndroidTV, but christ... I probably have to reboot this thing daily, because Netflix video randomly goes all black, or the audio randomly disappears. And rebooting is really slow. The entire thing is actually really slow. It will shut down randomly. It will turn on randomly (which can be really creepy when it happens in the middle of the night). Apps randomly will fail to work, requiring reboot.
The worst part is, they haven't made a single attempt at fixing it. Each time I check for system updates, it gives me the response "No reason to update :)". Fuck you , there's a million reasons to update. It's still running AndroidTV 8.0.0 , which literally means they haven't made a single update for it after releasing it. The last Android security update it has is from 2018, which is grossly negligent .
TCL has every hallmark of a company which puts in just enough effort to get the product out the door. The aesthetics is 10/10, with a huge thin display with almost no bezels. But when it comes down to living with this thing, I wouldn't be surprised if it actually only has a hamster wheel on the inside driving this thing. I'm 100% convinced they paid for proper design, then got the lowest bidder to make the software. It's crap.
This is what you get when you opt for "the most bang for your buck". You get a blowjob from a crack whore in some back alley. My sincere advice is to go for brands with a good reputation, like Samsung, instead of only looking at the price tag.

Android TV on Phillips is crap and has the same symptoms you described. I have a Roku plugged in to my Android TV.
