[Galaxy Tab 10.1 General] cryptyk:
OpenGL is the hardware acceleration library for Android. For an application like the browser, there can be two implementations of the "drawing" code for the application. If you wanted to draw some text on the screen, you could use either a bunch of standard text widgets, or you could render the text like a game would - with OpenGL. OpenGL lets you do things that a game would want to do, like scroll the text, rotate it, scale it, etc.

The OpenGL implementation of the browser would be much faster, and lets the device offload a lot of the graphical elements to the GPU.

Perhaps the problem here is that the keyboard (not OpenGL) is being composited on top of the OpenGL browser. That compositing implementation may be borked, or may be done in the CPU rather than the GPU.

So: Who's fault is it? Hard to say. It could be Google's implementation of compositing, or it could be the hardware vendors' (Samsung or Nvidia) implementation of OpenGL for their hardware.

I wonder if other OpenGL apps do the same thing. Someone find a game or graphic intensive application that also uses the stock keyboard and see if you get lag there, as well.

Great insight. I just won an ipad2 and immediately bought the xoom with intention if selling the ipad2 and breaking even, but this keyboard lag is killing me! The ipad2 is so much smoother. Google needs to iron these things out if they expect to make a dent in the tablet market.
[Galaxy Tab 10.1 General] cdf3:
I agree with the lag issues in the web browser. Sometimes it's so bad, I tend to wonder if taking my iPad 2 back for the Tab was a wise decision. I really hope TouchWiz can address that issue.
[Galaxy Tab 10.1 General] thepringlesguy:
I really am not having this issue

Is there any app to control HDMI features?

I want the phone display to be switched off when HDMI is connected. I use to watch movie but the phone display is on meanwhile.
[Xperia Arc Q&A, Help & Troubleshooting] jtdc:
This question also bugs me but I always forget to ask here. To have the power used efficiently we should be able to turn off the phone display right? Is there any way?

Fortunately my bravia has a USB port so it can charge the phone basically unlimited runtime. However when I take off the battery, the usb itself cannot fully power on the phone with HDMI on it. Therefore battery needs to be always installed as well.
[Xperia Arc Q&A, Help & Troubleshooting] DemonicHawk:
There's no way to turn the display off, though I've heard of using widgetsoid or any app that lets you set custom brightnesses to set the brightness to actual zero (display off).

Personally, I just set the brightness to minimum to reduce battery drain but I agree that there should be a way to turn it off when using HDMI.
[Xperia Arc Q&A, Help & Troubleshooting] jtdc:
In the video player (I use MX Video Player), the video playing can be set at the lowest brightness and the HDMI output is not affected. However if I use further screen brightness reducing app (example is Screen Filter) affecting entire phone display, that one affects the HDMI output, it gets dimmed as well, so its useless for the purpose.

What a basic thing but is not thought of. Strange.
[Xperia Arc Q&A, Help & Troubleshooting] carlomagno96:
First of all, please excuse my english, I'm from Italy.

Some times I watch some sport events in streaming on my Xperia-Arc through the browser (vipbox.tv)

Would it be possible to watch the same streaming on the TV, connecting the Xperia-Arc thorough the hdmi ? Or does this connection work only for watching the photoes and videos on the phone's multimedia gallery.

In other words, does the hdmi reply (/mirror) everything that is showing on the phone's screen ?

Thanks, Carlo

[HD2 Android Q&A, Help & Troubleshooting and Genera] janha:
Since this week I have a really big problem with my HD2.

November last year I started to install Android on my HD2, first on the SD card and then finally on the Nand (everything went well). Last week I installed one of the latest version and working just fine for one week it stagnated. I had to remove the battery, because nothing worked anymore. After that I got only the white starting screen with HTC and then nothing…

First I run Task29 and flashed it, HSPL, Radio, MAGLDR and then ClockworkMod Recovery. The result was that sometimes the white HTC starting screen popped up, tough I kept the power button pushed down, and sometimes I could enter the MAGLDR. If I finally got into the MAGLDR and tried to recover a backup or try to do a fresh/new install. I formatted the SD with the Panasonic SDformatter, but it didn’t had any effect. Finally I flashed the HD2 back to WM6.5 and the HD2 start working again (not very well). After this I tried to install Android on the SD card, but now the HD2 keep stagnates in the white HTC starting screen and nothing else works..

ROM: Boyppc Ginger 2.3.4 HoneyComB V27, with 150Mb system partition and an 1Gb ext2 partition on the SD card.

Is this a software or a hardware problem? Or both?

Can somebody please help me, because I have no clue how to repair this???

Best regards,

Janha,

hi guys,i'm trying to cook the D3D/2D drivers in to my custom but the drivers are not active.When the flashing end and i try to test the applyed drivers it seems that they are not installed.I'ed tryed the .cab to,no result.Someone who managed to get them working pls help me here...my rom is: WM 6.5.5 build 29020,and one more thing,what tweeks i have to apply for better menu scrolling ,2d performance?10x in advanced:D
[Windows Mobile] pcarvalho:
if your rom has 107mb of ram...simply...you cant use them...

they only work on non hacked nk's...

if im wrong please correct me ;)

cheers
[Windows Mobile] dany547:
is something about the memory distribution,but it works on 101mb
[Windows Mobile] ultrashot:
Try my scrolling mod. Attached.
[Windows Mobile] prabhat:
What does the 107mb holds here.. I see the driver works even when ~70 mb of free RAM.

Also just curious to know what hold the hacked nk with the display driver :confused: as I have hacked nk and have D3D too.
[Windows Mobile] Farmer Ted:
How did you get those physicsengine registry keys? And what is the small physics engine you've got in there?
[Windows Mobile] ultrashot:
That's a fake PhysicsEngine that changes these options and redirects all calls to PhysicsEngine_Old (original physicsengine)
[Windows Mobile] dany547:
so are are tying to say that not the Nk matters? today i'ed tested the native NK and the performance with that one was very poor.I want to stick with the 107 MB one because that one works very nice!
[Windows Mobile] dany547:
a few days ago i'ed tested a ROM (wm 6.5 build 23XXX) and it was mind blowing fast compared to mine,that rom had D3D drivers so i guessed that may be cause of the very nice performance!whats makes this job harder? that i have a very poor knowledge or programmer CODEs,that means that i dont know how to edit and adapt a .DLL lets say.My only power is Google,and aloooot of researching!
[Windows Mobile] dany547:
i managed to port the D3D drivers,but not i'm haveing problems with OpenVg.dll,the 2D acceleration works untill i put the device to sleep!
[Windows Mobile] dany547:
the D3d and 2D are working after i align the screen, if i restart the device i have to repeat the procedure
[Windows Mobile] dany547:
any solutions?
[Galaxy S II General] anoop19b80:
Hi People,

I have recently got Galaxy S2 and i was comparing it with my older Galaxy S(I-9000)

I was playing same video file in both devices with 0% & 100% brightness.

In my view, Galaxy S was more brighter and natural looking. Where as Galaxy S2 was king of dull. I mean say at 0% brightness, galaxy S was better and same with both the devices were on 100% brightness.

Technically Galaxy S2 screen is better.

Experts - Can anyone of you feel this way? or it is just my observation.

I have also kept the live wall paper "Spring Zen Free" that also was showing better on my galaxy S.

Even in setting screen, white text on black background was looking better in Galaxy S.

Any one has any idea why it is happening like it?

Plz plz comment.

Anoop.

You’ve probably read a little on other reviews about the video playback, it’s uniformly been reported as excellent. It is. In fact I would go so far as to say its peerless in the mobile phone world, and by a large margin (its nearest competitor being original Galaxy S as it happens,

Hello JJE,

Thanks for your quick reply. But could you please tell me that, at 0% brighness of both devices, Galaxy S2 is dull or it is same clear and crisp as Galaxy S?

As i feel it very much that, at 0%, Galaxy S is still brighter than S2.

Is it because they want to increase the battery life?

Kindly revert with your expert comments..

Hi JJE,

One last question on Galaxy S2. on the bottom tray of home screen of Galaxy S2, you will see "Phone" button which is has got a phone icon with Green background.

Do you see some sun rays like texture (diagonal small lines covering green portion) in the green icon? I just want to make sure that, I too have similar texture for that phone button and it is not something defect in the screen. (you might have to look closely)

Similar structure can be seen in "Applications" icon/button on home screen (which is blue in color)

Kindly let me know.

Anoop.
[Galaxy S II General] ph00ny:
Did you turn the screen power option off? even at 100% brightness, it's not actually at 100% brightness until you turn it off. Also go into the background effect to change the color temp
[Galaxy S II General] BarryH_GEG:
Play with these settings, it alters the display greatly...

Background effect: Dynamic, Standard, Movie?

Auto adjust screen power: Checked? Unchecked?

Browser brightness: Auto off? Auto on?

Display brightness: Auto off? Auto on?
[Galaxy S II General] leeboy22001:
I have to agree, s 2 is duller than my s (i now have both), maybe a power save feature that you can't turn off ? I've also noticed the yellow tint on s 2, compared to a blue tint on the s, and this can vary depending on what background effect you have selected ! This leads me to believe the colour temp could me changed in software. My itouch has a pinky looking tint compared to either galaxy phone.
[Galaxy S II General] ph00ny:
Which background setting are you using? Power save feature can be turned off by unticking.
[Galaxy S II General] dk206:
I've sold my sgs too. However there was a week when I had both and I can tell you for certain that the sgsII screen is more natural t in colour then sgs's. Having them both side by side the sgs just looks b l u e. Like really blue.

SgsII screen is the best mobile screen I've used

[HTC EVO 3D] tomh1979:
So wonder who's going to be using 3D pictures as avatars, or if it's possible to, do our avatars on xda have a size limit that would prevent us from that. I just think it would be neat to see that on our screens, lol.
[HTC EVO 3D] Overstew:
Aren't the 3D images .mpo format? Does XDA's server even support mpo formats?

EDIT: "Note: The maximum size of your custom image is 80 by 80 pixels or 19.5 KB (whichever is smaller). "

This probably means no, and 3D wouldn't look very 3D in an 80 pixel dimension.
[HTC EVO 3D] eman3316@optonline.net:
What would be the point if it won't look 3D to anyone that is viewing it? It will look 2d to everyone.
[HTC EVO 3D] tomh1979:
Yes it would look 2D to everyone, except to those who are viewing xda from their evo 3D right.
[HTC EVO 3D] tomh1979:
Which is what my query would be, so probably not possible do to size restraints.
[HTC EVO 3D] Overstew:
I'd imagine MPO files are larger because it's a mixture of two separate pictures put together. My XDA app shortens Avatar pictures to I believe even 20x20 (maybe smaller), so 3D avatars may be possible, but even if they were, it'd be near impossible to see or make out that they're 3D.
[HTC EVO 3D] mmace:
MPO is not a supported web format so the browser would not display it.
[HTC EVO 3D] eman3316@optonline.net:
Well first 3d only works when in landscape I believe. Also, I do not believe it can be mixed. Either the whole screen will be 3d on and the whole picture needs to be using the 3d aspect or it won't work. I do not believe you can view a 3d picture on a full 2d page when the screen is in full qhd.

Someone correct me if I am wrong.
[HTC EVO 3D] mmace:
yeah, if 3D is on, half the resolution goes to one eye and half to the other

therefore if viewing a web page which was 2D but the screen had 3D turned on (won't happen, but we're talking theory here) then the same image would be sent to each eye, making the page you're viewing just 480x540 (horiz x vert)
[HTC EVO 3D] nebenezer:
Yeah I don't see 3D avatars in the near future but I think a lot of people are underestimating the variety of applications, consumer and commercial, for 3D content. I think this phone is going to friggin rock.
[HTC EVO 3D] tomh1979:
It's only a matter of time, and developers will do awesome things with this phone.
[HTC EVO 3D] mmace:
so for that they'd have to develop a 3D web browser that uses non-standard images (jps or mpo at the moment) that the user would browse at half the resolution of the screen.

Sounds like a winner
[HTC EVO 3D] tomh1979:
So to do awesome things in developing, they'd have to develop a 3D browser, lol, at least quote the right post first, I can understand your response to my OP, but not so much to just what development they may come out with as I was speaking about in that last posting.
[HTC EVO 3D] mmace:
this thread is about Avatars in a browser and you state in said thread it's only a matter of time before developers do something awesome with the phone, apologies for jumping to conclusions
[HTC EVO 3D] lafester:
perhaps you can have a 3d sig?

have to admit thats a good idea for the 3d forums.

7: You should be at c:\nvflash in the cmd prompt now

Section 2: Putting tablet in nvflash ADX mode

1: Turn tablet off

2: Unplug the tablet from pc

3: Hold vol up(right vol button) then hold power button at the same time

4: Keep holding them for 15 secs

5: The screen will stay black the whole time

6: After 15 sec let go of the buttons and plug the tab in to your pc

7: Open device manager and look for APX Device listed with an error

8: Right click on the APX device

9: Select 'Update driver software'

nvflash --bl bootloader.bin --go

Section 3: Back up recovery (optional)

1: I included stock recovery in the files but if you want to backup recovery then follow this step.

nvflash --resume --read 8 part8.img

Section 4: Installing recovery-cwm_4.0.0.4-sam-tab-10.1 custom recovery

nvflash --resume --download 8 recovery-cwm_4.0.0.4-sam-tab-10.1.img

From the charging screen, hold power and left volume button. Screen will turn on and it will show the recovery icon and the download icon. Using the left volume button, highlight the left icon, recovery, and then press power to enter CWM. Now you use left and right volume buttons to move up and down, power to select items.

Get to that point, and then we can get you rooted.
