Smooth Library Scrolling on Tizen‑based Smart TVs

[LordVZlomka 6]

I have a Samsung Smart TV running Tizen OS. As I scroll through my media folders, I noticed that the scroll behavior is "jumpy" instead of smooth. Please add smooth scroll to TVs?

Hi, what model Samsung?

 This is already there but is dependent on the supported features of the TV rendering engine.

Samsung UN65RU8000FXZA. Other apps like YouTube, Netflix, etc, do not have an issue. If it were the engine, wouldn't everything be affected?

No, not necessarily. Maybe they developed something custom whereas we are relying entirely on native features. 

Also those apps you listed are probably Samsung partner apps and therefore have access to api's that we do not.

I've tried it on 3 Samsung TVs (different models) and it's the same everywhere. It's not laggy or anything, just not smooth. I've attached a video.

Is the UN65RU8000FXZA the newest that you have?

The UN65RU8000FXZA is a 2019 model. I know my friend has a newer one, and the third is from the same period. Unfortunately, I can't check the models for those two.

Hi All,

Just adding my 2 cents to this. I moved from an Android based Sony TV a while ago (that had smooth scrolling) to a Samsung , and I also noticed the lack of smooth scrolling, I assumed it was down to the fact that the Samsung runs apps differently compared to an Android TV. A little while ago I also asked about long pressing to show options. (I'm not chasing for a resolution or anything, I know developing apps across multiple systems can be difficult, just posting to highlight differences between how apps run and on what).

I've also attached a video so you can get a good visual as to how it looks.

All the best!

@FrostBytewhat year is your  model? Do you get a focus rectangle or focus scaling?

Q8FN = 2018

2.1.3

On my Samsung TV it doesn't have the smooth transition either like the Android app.  It just jumps between sections on the home screen.  Not slow, or laggy, but it just doesn't have the same smooth sliding effect as Android. The settings menu does slide out though (doesn't just pop out).

I also don't have long press which was confirmed with you using a usb keyboard awhile back.

We might be restricting what devices get the smooth scrolling a little too strictly, thus resulting in it only being used on the newest devices. We'll take a look at that. Thanks.
