HTC magician screen brightness

[tuyulaneh]

I have the o2 XDA mini and just realised that after i adjust the screen to maximum brightness. When u press the camera button, the screen suddenly increased its brightness for 1 second before it enters the camera function. When u go to tools->adjust, you can even see that the screen turns very bright and clear which is much clearer than the screen itself on maximum brightness. Anyone knows whether that this only is a defect in my device or happens in every HTC magician. Try it and please tell me whether u seen the screen differences. After having the device for 4 months then i realised this effect hehe. :?:

Your device is not defected it happens to other devices too depends on the rom that you're using.. ;)

[kolbac]

depends on the rom????
i tried a qtek rom and a imate jam rom and they have the same
behaviour, in camera mode the brightness is increased.
i try also to hack the registry keys, but nothing happens.
who can explain?

[gero]

Maybe its simply the camera application instructing the screen brightness to 'gain up' to make using the viewfinder for pictures in dark conditions more clear.

Alot of digital camera reviews say an camera digital display that gains-up at night/poor light is a plus as it allows you to see the subject of your photo more clearly (wanna buy a digicam and keep reading about this in all the reviews)

Could this offer an explanation?

Oh and P.s. My Qtek S100 with WWE 1.12 rom also does this.

Do you think that its possible to do something with the registry and increase them to same brightness as camera mode?? It would have amazing screen them!! I am really bad at registry tweaking hehe :oops: . Need advice from the pros pleaseee :lol:

[PdaAddict]

Did anyone figure out how to tweak the registry so that the screen brightens can be left at the higher level that it switches to when the camera is turned on? I would really like to keep my Jam's screen at that brightness level at all times. There must be something in the camera exe file that changes the brightness level beyond what is allowed in the settings.

Hey guys, I've made an ugly hack to achieve this - brighter screen as you get with the camera, but in normal use of the PDA. However, it prevents the use of the camera until soft reset.

What do you think, could you live with this compromise?

I'll second that ! :)

Guys,

After having a brainwave this morning about how to do this, I've knocked together a little app to enable it. However, the technique has some issues I want to sort through to make it a bit more foolproof for you guys. It's not a great way to do it, but it does work for now until someone can think of a better way.

I'm a bit curious why HTC didn't enable it by default. It's not MUCH brighter, but it makes a difference, and going back to the old brightness is quite disappointing!

Just keeping you all informed :)

Great invention again.. :D

More brightness can't be that bad i guess...

....but doesn't it drain your battery quicker ?

[Chatty]

I suspect this won't only affect battery drain but display lamp life time. May be this setting is slightly above specs which is ok for a few seconds, but it might most probably decrease your displays life time if you leave it enabled for hours.

That's my assumption why HTC did not make it available to the average user.

[vijay555]

I agree. As it happens, I might not release this at all.

For now it only works once per soft reset. After powering off, it goes back to normal brightness. Then you can only get the superbrightness again after a soft reset. Too impractical to be of any use, but an interesting idea for me to play with.

When i put my hands on the Qtek S100 (MDA Compact to be exact, in my case), i was so amazed by the screen and its high resolution/size (i never had a PPC/PPCPhone before) but a co-worker of me bought the SP5 (aka HTC. Tornado) and that screen is 4 times brighter compared to the S100's screen.

[vijay555]

Chatty - about the screen life. I guess it must be relatively safe if it's enabled by default in the camera mode. Potentially you can leave you phone in camera mode all day, and there's no automatic time out or power off or anything.

I imagine the issue is more battery life than screen life. And for most of us, I guess we'll all be upgraded in < 1 year?

@vijay555: So any progress in making it usable? What API is used for that? RIL?

[vijay555]

@Chatty, as I said in my earlier post, I'm not going to release this because it's not properly usable. Yet :wink:

The effect works, and you have superbrightness across the system, but only until you power off the system. When you switch on again, I can't get it to re-enable the superbrightness or the camera until you soft reset. HTC have used some curious programming. So it works once per boot for now, and that's nearly useless.

I'm only using a very dodgy hack to do this (which achieves the goal), but the best way would be to reverse engineer the camera/LCD drivers, and frankly I haven't looked into this at all, no time.

I doubt RIL would help, I think this requires direct interfacing to the screen driver/hardware.

My way is simple, and works, but not something I would put my name to as a release product...just an interesting trick for now.

vijay555, if you don't intend to release this "software" can you share the trick?

[vijay555]

kta - let me see if I can pack it together into an app that won't cause hardresets. Soft resets I can live with, hard resets are a pain in the bum.

The trick? Sure: start the camera, click on the tools button near bottom right (you will now be in normal brightness), choose tools menu, then adjust. You should now be in superbright mode. the trick is keeping it there :wink:

[Chatty]

I wonder if your program would work on my Magician because I have removed the camera.

[vijay555]

Chatty - what happens when you go into the camera program? Does it crash out? Did you physically remove the camera? Ouch, that's gotta hurt (the phone).

Offtopic, but work policy on cameras is a load of cr*p. I plugged in my ipod to work computer, downloaded 4gb of my desktop and took it home. What was I going to do, take a photo of myself? They have to focus on the realistic risk. USB is ++ worse then cameras.

I can't leave in that mode, if i minimize brightness become normal. What can i do to leave "adjust menu" open?

[vijay555]

That's the trick...

I'll try and pack the thing up tonight. No promises though, I have to go to the gym :(

[Chatty]

I physically removed the camera and when I start the camera program I can see it's title for half a second and then it's gone. That's all. And I did it because of a work policy. What they don't think of is, that you can transfer files via Internet. Even if you don't have direct access... you most probably get email access... and I don't need to tell anyone about steganography, do I? So as you said... they really shouldn't be worried about cameras :lol:

[code72]

We'll wait it. :lol:
Thanks Vijay

Guys, this isn't really possible. I was pulling your leg. :cry:

Only joking, look here (http://forum.xda-developers.com/viewtopic.php?t=31318). And RTFM.
