If it's a software glitch then you could hard reset

What tv is it?

No. Not software glitch

Almost every smart TV

you can install Vanced to an Android TV box so I think you could use it on a smart TV too.
make sure to use the non root version though.

trying to control it with a standard remote is horrible though, I use a mini wireless keyboard and trackpad.

Works on mine

When you go on you tube and selected a video to watch it keep on loading forever and never play

that's likely a YouTube problem, maybe their Android TV version has server side problems. a down detector type search might offer an explanation.

Did you hard reset though? Sounds like a cheap TV that doesn't get update support. What tv is it?

I update it. Same problem. I factory reset it. Same problem, the you tube only work true the browser.it happen on every Chinese smart TV except Samsung smart TV

Oh dear. Not a lot you can do then

I think the problem might be google play service

if it's Chinese check about device in settings, see if it has root switch or just install a root checker.

if it is rooted you can manually update play store and play services. thing is Chinese android products are built in the laziest way. instead of building a rom for the hardware they've made they'll take an existing rom and turn parts off, spoof some values and put it on sale.

if I give you a link to xda you can install Vanced manager and use it to put Vanced MicroG and YouTube Vanced on the TV without root. it's basically full YouTube minus ads and with controls over what gets displayed from the included YouTube options and onscreen ads too. the only problem with that idea is using via remote will be painful. it needs a mouse or trackpad, a keyboard too.

He hasn't got an android tv

all smart TVs are android

Nah, they're not

I just read that samsung is tizen and LG is web os but 90 percent of the rest are android so you weren't too far off

hmm, but they're all spies

OK
