Finally, hardware accelerated web browser!

Nice, very nice Finally, full hardware accelerated web browser!

Head to 50 seconds ...
Happy .. Happy .. Happy ..
I can now ditched Opera Mobile .

Hell, it's "finally, hardware accelerated UI!".

Lmao. Late to the party. One of the requirements of ICS is hardware acceleration of 2d elements of the ui/os. Its about f'in time google.
I voided my warranty and your mum.

I was hoping some of the browser controls would be at the bottom of the screen since it'll make browsing with one hand easier kinda like in opera mobile, reaching the top tab button will be a pita with your thumb with such a tall screen..

Is scrolling hardware accelerated too? One of the main reasons I liked samsung devices is because of the amazinh smooth scrolling.
Between the click of the light and the start of a dream.

The scrolling and pinching/zooming looks pretty quick and smooth.
I'd like to see the results of a SGS2 browser test ran the Galaxy Nexus: open a bunch of pages with flash videos playing at the same time (I think there were over 10), and then zoom/pinch one of them. The SGS2 handled that without lag. I'd like to see the HTML5 and Flash results from the GUIMark3 benchmark, too.
The Sunspider result is 1983ms (vs. 3385ms for SGS2, smaller is better) and the V8 version 6 result is 1387 (vs. 336 for SGS2, larger is better), so that bodes well for browsing on the Galaxy Nexus.

Cant wait for the ics to my nexus s. Damn smooth

Every video I see makes me more and more excited for ICS and the GN. So damn sick.

[Q] GPU rendering (smoooth scrolling) in Browser
Hi,
I can't find info whether Google implemented GPU scrolling in ICS ala iOS or Samsung in their latest 2.3.4+ firmwares for GS and GS2?
That's only thing that's keeping me away from AOSP (CM7 now), but if it's in the ICS now, I wouldn't care about Samsung abandoning SG1.
If anyone has NG, please try. Thanks.

From the videos I've seen, the whole os is hardware accelerated including the browser

Everything OS-wise is supposed to be 2D Hardware Accelerated according to the Android Code release page. However, it might be more sluggish compared to the SGS2, as they're both Hardware-Accelerated, but the SGS2 is only pushing 480*800 while the Nexus coming in at 1280*720.

The British tech blog, The Inquirer, posted a short review of the Galaxy Prime. This is what it had to say about performance:
"We certainly noticed the speed when browsing the web and opening apps, but we did notice a slight lag when changing the orientation of the device."
The article doesn't mention if the review device was running 4.01 that had the fix for video stuttering and whatnot.

You'd be surprised how little power is required to perform full 2D acceleration.

In Android Central's quick look video of the Galaxy Nexus that was posted today, the narrator mentions that the entire device is hardware accelerated multiple times.
I can't post links yet, but you can find the video embedded in the 4th story on the second page of Android Central. Likewise, you can search YouTube for "galaxy nexus, today" (without the quotes) and it's the first video.
Hope this helps!

I've just seen the video at the AndroidCentral.com. The browser is fast, but the point is not how quick you can scroll the page (it is quick), but how smooth is the actuall scrolling. If you saw iOS in personal (or Samsung 2.3.5+ firmwares for SGS1/SGS2) compared to AOSP, you'd know what I'm talking about.
No smooth browsing as I can see so far, unfortunately.

How do you expect to see 60fps smoothness on a heavily compressed 30 fps video?
And it's getting worse since there is no vsync between phone display and camera when recording the video (of course).

Do you see on the long webpage partial appearing of the page while scrolling on sgs2? On NG?

Have you ever tried Opera Mobile? Even on my SGS it has amazing performance, and you don't see parts of the webpage only render correctly after a delay. It's all 60FPS and rendered right away.
These guys beat Samsung and Google for performance. Only issue is their browser takes a few seconds to start up.

From this video I would say the scrolling in the browser is quite smooth. I had a SGS II before so I have the comparison.

[Q] Youtube playback grainy/pixelated after flashing IncrediblyParanoid?

Hey guys,
Forgive my ignorance, as I have searched high and low for any information on this, but I was running TazzSense 3.6 for quite a while with no major issues other than some lag that may have been more due to the apps I had installed, and on that ROM the video playback, including youtube in HQ, was clear and great. I tend to watch a lot of youtube videos. Yesterday, because I wanted to try it out, I flashed the latest Incredibly Paranoid after doing the super duper wipe and everything seems to be working great and I love the interface.
However videos on youtube seem pixelated and grainy even on HQ, compared to the old ROM. This seems to be isolated to Youtube or perhaps flash videos because other videos seem to be fine, but playing youtube videos through the app or a browser looks a bit off. I tried turning HQ off (looks worse obviously) and back on again. I also tried messing with all the combinations of Paranoid settings, which changed the look of the UI but not the video playback. I seem to notice a few rows of black pixels to the top and bottom of the video; it's my understanding that these videos are 480p in HQ, so in my mind should fill the screen, could something be scaling vertically slightly and causing the degradation in quality? Are there any other things I could check on? Any input greatly appreciated; if this belongs somewhere else please forgive me.

Yeah that's a bug in older job kernel. Wait for either new cm10.1 or pa jb4.2 or flash evervolv with new 3.0 kernel.

[Q] Best Screencast settings for be best results?

Hey all! I have a quick question to ask everyone. I make YouTube videos using Screencast Video Recorder and I noticed after getting a new phone, the Note 2 for Sprint, that my videos are pixelated? For example when I'm recording and I am not doing anything on the screen and just explaining things, the picture quality in that part of the video is sharp and smooth looking. But when I am moving around and opening things while recording, or playing games, the video gets blocky and the quality is just ruined. I had no problems with this running on my EVO 3D running at 25fps. So if anyone can help out on how to reduce the bad quality and have a smoother video that would be greatly appreciated.
My current settings for Screencast are: High video res, FPS: 25 (which is why I don't see why the video should be blocky looking since even the EVO 3D can handle that and the benchmarks say it can record in 40fps.)
I am wondering about actual phone settings that might help me out. Since I'm running 4.1.2 I have to have Force GPU rendering on in the dev options as well as Disable hardware overlays. I was wondering if turning power saving mode on would help but only have screen power saving check since that lowers the actual screen frame rate maybe that will work?
Since I can't post links yet, search BambiTyer on YouTube. Or /BambiTyler.
*scroll down to recent uploads, the uploads of Minecraft and "Is getting an LTE device worth it?" are two videos recorded with the Note 2.*

Tab S 10.5 YouTube Video Stuttering

Hi guys, I recently bought a galaxy tab s 10.5 and I'm having issues with video playback in the native YouTube app. Basically every 5-10 seconds, I would get a micro stutter, as if the video is slightly jittery. It's definetely not buffering as the video has loaded well ahead already too.
I am using the samsung stock OS so 4.4.2 and I have installed all the latest official updates for both the OS and the Youtube app.
I have also tried a factory reset of the machine, clearing the cache and updates for the Youtube app and reinstalling. I've also tried forced GPU rendering and turning off hardware overlays in developer mode
Does this indicate there's an issue with my hardware ? It does not happen when i stream videos from my PC over wifi or any locally downloaded videos. Any help would be appreciated. Thanks.

Hmmm, never had this problem with mine when it was on stock. I usually had this problem when I underclocked my cpus and all that or when I am using to many appps.
The only thing I can suggest is use another app (viral popup https://play.google.com/store/apps/details?id=com.Mata.YTplayer ) or take it back to be safe.

Thanks, yep the youtube videos would stutter even when i freshly restarted the tablet so nothing else really is running in the background. I have tried the viral popup app except it seems to play at a really low quality setting, ,ie 1080p is not available ?
Is there anything I can test to see if its a possible hardware issue ? I ran the Antutu benchmark and got 37k which seems in line for what's expect from this tablet. Does this help rule anything out ? Thanks.

Check processes, there's probably something in the background.

I dont think so. When you play games does it lag too? Ex real racing 3 etc? Because if it cant play youtube without the micro lag, that may affect other apps. I dont get any lag while I was on stock.
If any other apps lag while playing (not on loading screens) then it may be an issue. I never had any micro lag on mine so it may vary on how you see it. Of course we have custom roms that are way smoother (CM12) but I am unsure if your issue is hardware related or the way you see it. Hope this helps!

I got youtube stuttering too for months on my TabS ST800, I tried every tricks in dev options, nothing ever changed .
But one day i tried the CARDBOARD view in the YouTube app options and then return to normal 2D view.... motion became butter smooth up to 1440p60, for any video! If closing youtube app and restarting it, it is stuttering again, until opening again the cardboard view.
Here is a test video I used to validate stutter-free playback :

You, sir, are awesome!!! I had this problem for the last couple of months on my Tab Pro 10.1, tried everything to eliminate it. Going back to Stock or GraveD rom was slightly better but not really smooth either. I was beginning to lose my sanity switching back and forth between CM11, CM12.1 and stock-rom, trying different developer-options but was not completely satisfied in the end. This cardboard-step is a temporary fix i can definitely live with. But I'm surprised that not many people seem to be effected by this stuttering or they simply don't mind at all. Hope that google is going to fix this shortcoming in the near future but meanwhile...Thanks a ton mister :good:!

I was so happy too I spent a night watching again many videos I love ! I'm glad I could share that little joy !
To answer your question, it is a shame that people are suffering from the belief that "online" videos on computer, tablets or phone *must* somewhat stutter. Well ... even trans-galactic communications in Star Wars/Trek and other sci-fi movies are depicted with stutter and even analog (!) video sync and lines issues (in 2150!!). Stutter and other digital disorders have been imprinted in the modern culture because not much effort was given to understand (and implement) that we human are analog creatures requiring a natural constant flow of sound and light, not a "best effort" variable low frame sample rate due to "unavoidable" system interrupts between storage, cpu, gpu and screen. Remarkably, Apple hardware/software was always close to perfection due to their close collaboration with the computer graphics industry for tv and movies..
It is indeed so much enjoyable when colors, contrast, motion of a clean picture hit the brain which then do not have to interpolate, filter dynamically and overcome an unpleasant stressfull and therefore tiring "motion picture"
So far only Sony with its X1 graphical processor in TVs is IMO able to achieve a minimum of digital artefacts while interpolating and displaying moving pictures. HD was a attempt to increase resolution (but we lost many qualities that the oldest of us enjoyed with CRT tubes). UHD must bring "better pixels" back with constant higher frame rate, higher pixel resolution and higher color resolution and dynamic range.
I hope to say bye bye soon to "flicks" = flickering judderish stuttering color-ish moving pictures.

Snapdragon S10/+/e owners please read: Possible bug with lag and stuttering

Guys, before you reply with any feedback, please read the following post and links in full. It would also help if you posted details of your device like the following, which is mine:
Model: SM-G9750 (Hong Kong S10+)
Build number: G9750ZHU1ASF1
Completely stock, no settings changed
Only YouTube Vanced installed (for testing purposes)
Click to expand...

Summary: An intermittent stutter or lag (most notably during fullscreen 4K HDR playback, in my case) which only goes away when you activate certain screen recorder applications like Game Tools or AZ Screen Recorder.
Below is a list of posts that highlight this problem that I and a few others are experiencing. The common denominator here is the use of a screen recorder, which removes any present stutter or lag.
https://forum.xda-developers.com/s10-plus/help/lag-stutter-overall-choppy-t3914381
https://www.reddit.com/r/galaxys10/comments/btwfbl/anyone_experiencing_stuttering_or_frame_drops_on/
https://www.reddit.com/r/galaxys10/comments/b79cw3/is_snapdragon_really_that_much_worse_than_exynos/
https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/ (video evidence of problem)
The following two are from myself. My problem is that all 4K HDR content (could extend to other formats also but I need to do more testing) is stuttering or dropping frames. Screen recorder on and boom - it's smooth.
https://www.reddit.com/r/galaxys10/comments/ch172q/snapdragon_owners_does_this_type_of_video_play/
https://forum.xda-developers.com/s10-plus/help/sm-g9750-video-playback-throttled-t3950757
The lag returns as soon as you deactivate screen recording, which suggests that this is either a bug with the CPU or GPU not being optimized or boosting its frequencies properly, leading to these stutters.
I've put Snapdragon in the title as these posts all appear to be from Snapdragon owners, whether it's the US or HK variant. I don't recall ever having this issue as a last generation S9 Exynos owner. If you are an S10/+/e Exynos owner and encountering this issue, you could still try using your phone normally, with a screen recorder active and then without, to see if there is any performance gain (as crazy as it sounds, it might actually make a difference).
Below is a test I'm using to demonstrate my problem. It involves installing apps (namely YouTube Vanced and either one of two screen recorders I've tested it with), so it's not the most convenient. If I find a better method, I will update the post accordingly.
You will need YouTube Vanced. I'm suggesting Vanced because the original YouTube app doesn't let you view at 4K resolution.
Firstly, open Vanced and tap the account icon in the upper right. Go to settings, Vanced settings, Video settings and then toggle Resolution Checks to ON. Refresh and restart the app.
Now open Game Launcher, tap the three dots in the upper right > Add apps and add YouTube Vanced to the list. We're doing this for the screen recording function which I'll mention later.
Note: if you don't have Game Launcher or Game Tools, you can try AZ Screen Recorder as an alternative. Nice Shot does not work.
Once that's done, here's a 4K 60fps clip for you to try. It should be easier to perceive any hiccups with the higher frame rate. Please set the resolution to 2160p (tap the three dots in the upper right) and watch in fullscreen / landscape orientation:
https://www.youtube.com/watch?v=LXb3EKWsInQ
Panning shots work best. For reference, see points 0:19, 0:46, 1:48, 2:14, 2:42, 3:04, 4:11 and 4:41 in the video. Does it look like it's stuttering or dropping frames intermittently?.
Now, swipe up from the bottom of the screen to show the navigation bar (you need the navigation bar enabled to use the recording function) and tap on Game Tools, which is the leftmost button. Tap Record.
While the screen is recording, are the stutters now gone? To my eyes, the video plays back perfectly while the recorder is active.

Well if you have a better solution then I'm all ears? I left a similar post in the Q&A section and didn't receive a single reply. So I thought I'd post it here instead since it's more active.

[email protected] is where I experience constant stutter. You will need to override resolution checks in Vanced to watch at that resolution: Tap the account icon in the upper right. Go to settings, Vanced settings, Video settings and then toggle Resolution Checks to ON. Refresh and restart the app.
Don't forget to try it with the screen recorder on please, to compare if playback is smoother.
Just realized you're on Exynos, so the issue might not pertain to you, though there's a chance I might be wrong in that regard. Thanks for testing though - more feedback is always welcome :good:

or

You will also need a screen recorder of some sort though, that's the most important step. Here's a few:

update: Nice Shot doesn't work for this test.
Appreciate anyone else willing to try, of your own volition of course. Doing this purely to raise awareness on the issue and gather feedback.

I just tested this using the supplied download links for the actual video and AZ screen recorder.
In all honesty I couldn't see any difference between the video running with or without the screen recorder recording it. They both looked smooth. I was using the default video player to watch the downloaded video.

That looks like the Samsung video player, but no matter since the problem persists across other players too. MX Player in HW decoding seems to be the worst performing one for me.
Did you watch in landscape fullscreened? I keep forgetting to add that detail. If it was the same regardless, then I guess that removes the US Snapdragon from the equation. But thanks for taking the time to test, much appreciated :good: People probably think I'm bullshitting but once I find a concrete way to show what I'm experiencing, I will update this thread.
So far I've only had confirmation of this problem from two (yes, only two but it's still something!) other people, and they also happen to be owners of the HK S10+ variant like myself. If there are any other HK owners out there, I could really do with your feedback on this too!

Yes , I watched it in landscape mode, even compared the first few scenes where the camera pans etc with screen recorder on and off, couldn't tell the difference.
Maybe you could film the issue with a camera for us to see ?

Mx player with hardware decoding is no problem, smooth as butter. Snapdragon U1.
What does YouTube report with nerd stats turned on for the dropped frames line?
No offense but your premise is flawed at best. All you have done is made a subjective claim backed up by no legitimate measurable evidence..
Having people install screen recorders and play videos is not 'testing' anything..
Best of luck

That's been tried by someone already but the thing with these cross-comparisons is that they aren't conclusive enough for some people. For me it's crystal clear because I already know what to look for.
Here, this link was in the OP: https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/
One on the left is HK S10+, Exynos S9+ on the right. Make sure it's in [email protected] so it's as clear as possible.
The most obvious thing is that the scrolling is laggy on the HK model, but if you look closely, the video is stuttering too (look at the zooming out shot at the beginning). Exynos is completely smooth.
Stuttering video is a big no-no for me, really should not be happening on a phone of this spec.

Okay fair enough my test isn't the most thought out, but if you have any better suggestions on how to demonstrate the problem, you're more than welcome to provide them.
Stats for nerds doesn't show dropped frames, so it's likely that any FPS monitoring software would be useless too.
No it's not a subjective claim because if you read through the post and links in full, you would see a number of people confirming the problem. Doesn't matter how few, it's still an issue that shouldn't be ignored.
And one of the links has evidence in the form of video comparison: https://www.reddit.com/r/galaxys10/comments/b4nftn/snapdragon_s10_laggy_on_4k_youtube_playback/ please watch it @ 1080p60 on something larger than a phone screen.
The one thing I should've probably clarified is that I'm on the HK S10+, but those links indicate that US variants have a similar issue too. If yours doesn't have it, then cool, you're good to go :good:

One on the left is HK S10+, Exynos S9+ on the right. Make sure it's in [email protected] so it's as clear as possible.
The most obvious thing is that the scrolling is laggy on the HK model, but if you look closely, the video is stuttering too (look at the zooming out shot at the beginning). Exynos is completely smooth.
Stuttering video is a big no-no for me, really should not be happening on a phone of this spec.

So now we're talking about the scrolling when the video is played minimized like the reddit video? Yes mines like the same laggy. But the video itself full screen is ok.

Not the scrolling specifically because that's related to the problem. For me the scrolling is laggy AND the video stutters. Are you sure the video is completely smooth? It might seem so but on mine there are frame drops present - even if it's very minor, there should be none at all.
It's best to compare with another capable device side-by-side with your own eyes, as no video recording will be able to demonstrate this clearly enough. There's also a chance that some people aren't sensitive enough to stutters and might not even be able to perceive them (I'm not saying you are, this could genuinely not be happening on your device).
And even if the video doesn't appear to be stuttering to you, shouldn't the laggy scrolling be enough cause for concern? A last gen phone is running smoother and that's not acceptable. Don't settle for mediocrity guys.
edit: before anyone questions the absence of screen recording in that video, the person who uploaded it has another post on reddit where he mentions it fixing the problem.

Watching it at 1440p on native YouTube app it seems the scrolling is smooth. But on Vanced @2140 not so smooth scrolling. Probably the Vanced app or cpu etc binning on the snapdragon.

I don't think it's the app or hardware because once I turn on the screen recorder, playback is perfect (landscape). I'm no expert on this but a logical guess means there's a frequency boost while the recorder is active, removing the stutters.
If I could find a less ****ty workaround that does the same, I would be okay with it, but there isn't

No lag here. My phone has been flawless. SD
