Hi DROID Charge owners!



Samsung was so kind and sent me an Infuse 4G to help me developing for it. Thanks Samsung Mobile Korea

Infuse use a beautiful huge 4.5" Super AMOLED Plus screen.. But its driven with Galaxy S screen settings
DROID Charge is very similar to the Infuse 4G, except the display is a tad smaller. Super AMOLED Plus screen is also optimized for non "Plus" aka Pentile matrix.
That's why by default everything is over-sharpened and colors over-saturated.

I added preliminary support today for much more faithful screen settings in my one of my in-dev apps "Voodoo Screen Tuning", available for free on Android Market.
This app is very much experimental and not a final product. See it as an internal leak from a R&D lab. But as Linus tells: publish often, publish early

Please take a look at the app description, and have fun testing this app!
I need your feedback, so.. see you soon.

Installed, I see there are two options, native and samsung. I assume native is to return to stock and samsung are to switch to the optimized settings? I got superuser request and approved after hitting the samsung button. Didn't notice anything immediately so I rebooted to see if that would make a difference.

Don't know or can't tell if there is a difference.

Any way to tell? Good news is it didn't crash on the charge.

Native is screen without sharpening or color boosting.
Samsung is.. Samsung default.

I don't own a Charge for tests so.. only you can tell me

I installed and swapped between the two. I couldn't tell any difference.

I am on a voodoo kernel so I wonder if that makes a difference...

The Native setting is *much* sharper than the Samsung setting.

Very nice.

I don't see any immediate changes in the look of the screen, nothing changes (or it's so slight as to be unnoticable, and I do have pretty good vision) when looking at a high res picture with the overlay on and cycling back and forth.

But it is doing something, the button backlighting turns off and turns back on, but only when pressing the native button. Or maybe I'm seeing things from staring at my phone for the last 10 minutes like a jeweler setting a diamond or something.

Edit: It is sharper on native, very small text is more defined. Cool.

Same here. Not really sure which I prefer, native looks a lot sharper but samsung looks a lot smoother due to the blurring effect.

Samsung setting is over-sharpened, which means it should "look" sharper, but all it does for real is exhibiting a ton of artifacts.

I guess it's why you find "native" sharper, because it just display accurately pixels as they're supposed to be
− apply sharpening general UI elements and text really makes no sense to me, so it's not the case anymore.

Also: note that if your eyes are accustomed to an artificially sharpened image, the normal one looks blurry for a few seconds in comparison.
But that's just an optical illusion.

Does the setting stick across reboots, or does it have to be reset every time?
