XPeria X10 Camera App with automatic LED switch

Thu, 29 Sep 2011 14:01:10 GMT

(Sorry the english. I used the google translator)

Hello everyone!

A few days ago I upgraded my XPeria X10a (carrier TIM BRASIL, branded) with Android 2.1-update1 to   version 2.3.3. The new version of ROM is XPeria X10i (debranded). The   ROM was obtained at XDA Developers, but seems it is an official version.

Everything is working fine since then, but yesterday I decided to take a picture in low light conditions, and the camera's LED (which I call a camera flash) did not activate automatically.   I'd Look for an option in the settings and saw that there is an option   to "turn on the flashlight." By turning on the "flashlight", the LED is turned on and activated continuously until to be deactivated

I'm absolutely sure that when I first bought the phone (X10a with Android version   2.1-update1 TIM BRASIL carrier branded) and tested a photo, the LED was turned on automatically in low light condition (or simply turned on regardless of light condition), and this does not seem longer be happening with X10i Android 2.3.3 debranded.

I have read several places that the X10 does not have this functionality, but as I said, I remember perfectly that when I took a picture of my mother, the first picture I took with the phone, she said, "a light went on here", and i said "It's the flash". Of course is not a flash, it's only a way to make clear photos. But I'm sure this LED was turned on when i pressed the photo button.

It may be that when activating the camera, even without pressing the Photo button, the LED will turn on and stay continuously on until the camera is turned off. The fact that the LED is turned on without I need to activate it via the menu and it's not happening anymore with the new version of Android (or was it a limitation of version of "i" that was not present in the version "a"?)

Summary / New info:

My old ROM was the original XPeria X10a ROM. The brand carrier was TIM BRASIL and the Android version was the last official version of Android on this phone, Android 2.1-update1. To activate the camera I pressed the camera hardware button until the phone vibrate, and then, while the camera was focusing the object, the LED was turned on. When the photo was taken the LED blinks and turn off just like the XPeria X10 min pro from my girlfriend. This behavior in X10 mini pro I can prove, as the Android version of the X10 mini pro from my girlfriend is still intact.

Please, this is very strange and must be known by everyone. THERE ARE a X10 official ROM with automatic camera LED switch, and this is not a guess, this is an affirmation. So, what is this ROM? How to "patch" my actual ROM to get the correct behaviour of camera LED?

Em português agora: Se há alguém aqui neste fórum que comprou este telefone na loja "Ponto Frio" pela Internet (telefone XPeria X10 desbloqueado TIM). Por favor, entra em contato comigo por aqui de forma que possamos confirmar que esta funcionalidade realmente existe.

I tested multiple X10i and X10a firmware versions and I'd never seen automatic LED light at all, you can download apps that will do so or something similar

the X10 mini and X10 mini pro have LED Flash but NOT the Xperia X10

It is ... Maybe I confused about the fact that the official 2.1-Update1 ROM, have the feature of automatically turn on the LED. But after some research on the net, I saw that this is nonsense because turn on the LED is something 100% controlled by the camera software.

So the developers removed this feature without reason! The proof is that I decompiled the X10 2.3.3 stock camera application (.smali files) and I got the LED automatically working at the time the image is being focused. I still cannot perfect the behavior of:

1. Turn on the LED while the image is focused

2. On focus done, turn on off LED

3. When the picture is taken turn on the LED and after that turn it off

but when I can I will publish for everyone to enjoy this so simple behaviour...

That'll be great if you can do it

Well I did it, but its not perfect yet. I got the folowing behaviour:

On turn ON camera, the LED is OFF
On focus the LED is turned ON automatically
After the camera get the focus (green square on screen) the LED continues ON
Take the picture (LED continues ON)
Picture Taken (LED continues ON)
Picture saved (on Preview) LED is turned OFF

I want to get the same behavior of X10 mini Pro, it is:

On turn ON camera, the LED is OFF
On focus the LED is turned ON automatically
After the camera get the focus (green square on screen) the LED turns OFF
Take the picture (LED turns ON)
Picture Taken (LED turns OFF)
Picture saved (on Preview) LED continues OFF

The steps to change are 3, 4 and 5. To change it, I need more time to understand the "smali" language and the Android SDK. Anyone with these known can help me.
