Scrolling smoothness - Samsung Galaxy A20 Real Life Review

Some phones exhibit choppy scrolling, especially when navigating long web pages when multiple apps are running in the background. Rate this thread to express how you smooth scrolling feels on the Samsung Galaxy A20 under such conditions. A higher rating indicates that scrolling is always buttery smooth, even when you're reading a 10,000 word article on "how to kiss a girl".

Chrome is a better browser than Samsung Internet on this phone. It scrolls smoother. It launches faster. It switches tabs faster and smoother.
The browsing experiencing is fine with hiccups happening only when switching between heavy tabs. It also has this weird bug where while opening a website, the controls disappear and nothing can be done in the browser! You can't switch tabs, you can't scroll blah blah.
Scrolling in other menus is passable if you give it time to load. If you launch the settings app and go to the Apps section, you have to give it time to fully load the list or it will run on 2 frames per second/it looks like a slide show.
Apart from the settings app, scrolling is otherwise smooth for its price.

[Q] Vertical Scroll lag in DEFY

I'm planning to buy the Motorola DEFY. I was able to try out a demo piece for some time at a store .... It seems to have a vertical scrolling screen with icons as well as a set of horizontal scrolling home screens with icons. While the horizontal scrolling seems snappy, the vertical scrolling seems a bit laggy. As I install more apps, will the vertical scroll lag increase further. What's the point of having both those screens anyways ? Most phones just one horizontal scrolling ?
Horizontal is similar to your desktop. You put shortcut of apps or widgets based on your preferences. The vertical is the one where all apps are located. This is where you get the apps you want to put in the horizontal for easy access. lag can be reduced depending on the number of apps and settings

Hi!
The lag is, I believe, for the caching of icons. Because, once icons are cached (meaning you have been through all icons in the vertical main menu) try scrolling and it will be buttery smooth! Ofcourse, the more the apps, the more time it takes to get the icons cached, so more lag. But what I have noticed is that even though the main menu has been cached, the lag appears unpredictably. I suggest launching apps frm search since its faster.

As mentioned, the more apps you add, the slower it may get.
But maybe the android version (eclair, froyo, gingerbread?) on the phone you used wasn't too much up to date, or some laggy application was running, these could have affected the performance of the phone.
I use LauncherPro on my Defy (gingerbread CM7) and it has the option to hide (unused, unwanted) apps on the app drawer, which also increases speed.

Minor things HTC *needs* to fix & fast

Aside from the major issues that some (But certainly not all) people have been having with corruption/screen flicker there are still quite a number of minor issues that could do with a bit of work.
Live wallpaper bug w/ Rosie
Certain games that should not lag end up lagging (Despite CPU usage being quite low throughout). A good example of this is stair dismount. Shadowgun THD on the other hand runs smooth as butter. Obviously, a driver update is necessary.
Although very infrequent, the interface stutters from time to time. HTC need to fix 2D hardware rendering.
HTC Gestures causes far too many issues. It needs to be fixed, not just disabled.
Camera framerates can dip even in good lighting conditions. HTC needs to either up the bitrate or find some other way of increasing framerate. The phone and sensor are certainly capable of it.
The stock android widgets are incredibly laggy and don't update properly (The GMail widget in particular). The Sense mail widget is fine so it's certainly not for lack of performance.
If anyone else has any issues (EXCEPT FOR SCREEN FLICKERING as that doesn't affect everyone) could you please add to that list so we can send it to HTC?
I know this has been said in many threads. But the laggy scrolling between homescreens is driving me nuts. Its not bad unless you have a lot of widgets. This is even using HTCs wigets.
Download Apex and add as many wigets as you want. Smooth as butter. So the phone is more than capable of handling this.
Also - When using live wallpapers the animations stop for a sec when swiping between homescreens. This also should not happen. It also works flawlessly on apex.
I wish they would fix the unresponsive screen issue. Can't tell you how many times over the last few days I've nearly thrown the damn phone up a wall while trying to play a game and the screen has stopped registering 1 or all touches
Have you turned off HTC Gestures? I had the exact same problem until I turned it off.
-Double push headset button to skip song
-Bluetooth Audio lags
-Option to change multitask button en disable on-screen menu button
-MUCH better performance
-MUCH better power management
-Browser lags!
-Camera sensor is véry high-end, so somehow it must be the software that makes the picture look worse than my old SGS II camera. (both on default setting)
Please HTC don't dissappoint us, the hardware is perfect so don't screw up the software

Buttery smooth
Chrome scroll great, Twitter scroll horrible.
I think there's a problema with Twitter app on most phones...
Twitter lite instead working like a charm
Jelly Scroll
Am I the only one experiencing jelly scrolling like the one found on one plus 5. It's not that bad as OP5 but still present.

Yep, you're right about jelly scrolling effect on ZUK mobile. I got ZUK Z2 PRO and got the same "problem". And actually it's not a problem. It's kind of FEATURE. Or flaw to be precise. AMOLED display are causing this issue, which is not visible to everyone (depend on eyesight). But it's not visible if display is correctly installed in device. If it's installed upside down, it's noticeable. Similar issue got OP5: https://www.theverge.com/2017/6/29/15894850/oneplus-5-screen-jelly-scrolling-statement . Just try to open browser, turn your phone upside down and start scrolling -> you wont notice jelly effect anymore. Strange that ZUK or OP didn't think about it during developing their phone. Such a pity. But nevertheless, we got some special FEATURE
Occasionally horizontal swipe is taken as vertical swipe, say swiping off a notification will do scrolling!
While charging there are some issues with the touch. Holding and dragging an icon is not possible while charging! :/

Have you test frame drops with gpu profiling?

You can find it in developer options, if you actívate it you will see a lot of vertical lines and an horizontal green one.
This is used to know if the phone is butterer smooth, 60 fps, if the vertical lines go over the horizontal then there is lag...
Could you try this with scrolling apps like Twitter and Google Play? Say the rom you are using and the governor if you changed the rom's default one

Laggy And shuttering UI & apps

Hey,
I replaced my iPhone SE with Huawei Nova 3 and I am experiencing a little bit laggy UI. Especially in third party apps like messenger and Instagram. When new message comes and I click on the messenger popup(circle which is always on top) then animations are shuttering and are a bit laggy. The same happens in Instagram apps when looking at the stories, then doing gesture to leave stories (slide down) and then u see these shuttering animations. Is anyone experiencing similar issues? Maybe it is android issue, but I am just not used to these kind of lags on iOS.
You will hardly see lags from iOS unless it's a badly coded app or it's run out of memory. I've experience this on the Nova 3i and I just replaced the launcher with Nova Launcher (fitting names) to reduce the lags. Especially when opening apps and transitions. Also disable any apps to launch on their own after a reboot helps sometimes.

It helped a little bit but still. Instagram just behaves weird, still the same problem occurs. I think android apps are just not yet optimized for this weird resolution, because when launching app for the first time, I see in ca half of the apps that they are somehow resizing themselves too match the required resolution (and that is also when some resizing/shuttering is encountered).

On my device there's an option to disable full screen per app. But on my device IG supports full screen. I do notice fb, fm, IG, flipboard lags when scrolling especially when there are posts with videos. And especially with videos that autoplay. I notice the same lags on my iPad pro 12.9" also. I always disable autoplay on the apps.
