Long white blank screen after taking a photo - Touch Diamond2, Pure General

Hi,
One thing I dislike on the Topaz just after shooting a photo is that long white blank screen probably displayed while jpeg compressing.
I didn't notice specific times between low res and high res pictures but shooting 5Mpix with high quality takes about 3 sec of blank screen (btw I would have preferred black blank screen... less battery consumption).
Did you experience the same thing on your TD2?
Is there any feature to optimise this? (code with asm to speed up the jpeg compression...)
Cheers.

Imported Photos not full screen

Pictures taken with the HD2 once selected automatically take up the whole screen and then you can zoom in further. I have imported photos well larger than the resolution of that taken by the camera and they are all cropped with a black border on top and bottom. I have tried resizing to 400x800 and 800x400 and 1024x480... etc and can't get my photos to display full screen like the stock included pics as well as all taken with the camera. Any help please?
the HD2 screen resolution is 480x800. Your photos need to be ratio 1.666....length/width.

Bad displaying of gradients in pictures

I'm not sure whether this is a problem with Android (doubt it), HTC Sense in general or the HTC Photos app..
But what I'm finding is that pictures with gradients (usually ones computer generated) have their gradients shown very bady and makes the picture look terrible. Instead of doing a smooth colour transition, it sort of does it in chunks..

As you can see here, isntead of fading smoothly from the red to black, it does those ugly layers. I first noticed it when I had this picture set as the lock screen picture because it does it there too. In bright light its almost impossible to tell, but in the dark it tooks terrible.
Sometimes when I look at the full picture in the Photo app it doesn't do the gradient so badly, but when I go to pinch zoom the slightest it instantly changes to look like that. (isnt just a problem with the one picture btw). I thought it might be something to do with the large picture being resized to fit the screen, but I resized the picture on a computer to be smaller than the screens dimensions and it does the same thing.
Another slight issue I picked up is that black areas in a wallpaper picture don't show as 'true black'. When I view the picture with the black background fullscreen in Photos, the black areas are true black (tested at night - true black of AMOLED screen). But when the picture is set as background, there is a noticeable difference between the blackness of the background and the 'true blackness' of the bottom of the notification bar...
Might be hard to see, but to show what I mean:

Does anyone have any explanation for these problems, and even better, fixes?
I've got HTC Legend unrooted

[Q] Home screen wallpaper quality

When i'am seting picture on my home screen it changes the quality of the picture. It makes less better. How to make it to show picture in a best quality ?
Sorry for bad english.
if the picture is smaller than the screen of your touch 2
the picture quality would decrease automatically and if you are trying to set a picture that is bigger than the screen the quality wont decrease but u wont be able to view the whole picture
try looking for pictures that match your touch 2 resolution
I'am trying to set a much more bigger then the screen is but i get bad quality

Wallpaper slideshow without cropping - solution

Got a Nexus 7 on black Friday. I've used pictures of Serenity, from Firefly, as wallpaper pictures on my Android phones for years. When I tried to use them on the Nexus 7, I kept getting the frustrating cropping issues people keep talking about. I finally sat down this morning and found a solution. The first key is to use an app that doesn't scale the pictures. I'm using "Photo Gallery Live Wallpaper". The next step was to find the right picture dimensions so the picture on the wallpaper matches the picture file resolution exactly. This took some trial and error using pixel grids.
The Nexus 7 screen in portrait mode is 800x1280. The wallpaper picture sits 48 pixels above the bottom of the screen. So a 1232 pixel tall picture sits properly in the screen. Using the default launcher, the notification bar at the top of the screen is 48 pixels tall, and the navigation bar at the bottom of the screen is 64 pixels tall. So, the top 48 and the lower 16 pixels of the wallpaper pictures are covered up. For each of the two pans to the left and to the right of the center home screen, the background image moves 150 pixels. With the center home screen 800 pixels wide, this means that a 1400x1232 pixel image will display properly.
I've made 9 background images this size, and the wallpaper app seems to be cycling through them all properly.

Nexus 7 new display + digitizer pixelated disaplay

My Nexus 7 (2012 model) display got broken and I've purchased new Full LCD display+Touch Screen Digitizer (from: http://www.aliexpress.com/item/Orig...itizer-for-ASUS-Google-Nexus-7/767556272.html).
Touch screen is working fine, but the display is not working correct.
Problems:
Images is pixelated all the time. Always
Display is not coming properly. Ex: settings screen is supposed to be smooth gray gradient, but coming as color palette (color bars) instead of smooth gradient. (see image 7)
Previous screen is seen next scree. Ex: in settings screen I can see home menu icons (highlighted with red lines)
Sometimes pinkish color is coming, and sometimes whitish tone is coming
I've attached few images I've taken using my Mobile and few screenshots I've taken directly from Nexus 7. In the screenshots you can see the images are pixelated.
Where could be the problem? How does the screen capturing works in Android? I mean as I've taken direct screenshots and those images got pixelated, does that mean problem is with GPU or does Android will capture the image some home from the display?
Can any one tell me how Android screen capture works?
If Android captures what it is sending to display, then the problem is with GPU.
If Android captures the pixels from the display (some how after shown on the screen), then the problem is with LCD.
Can anyone suggest what could be the problem?
(I've attached images as zip file, as direct image upload is lowering the image quality and one may confuse about the actual problem)
Okay, I think I got an answer (or at least part of it).
Answer: Android captures what it is sending to display (technically, from something called FrameBuffer).
So, I think I've problem with GPU connectivity (may be some loose connection?). Can any one confirm?
