Screen Brightness hack? - General Topics

hi guys,
just got my Dopod 838 pro(TyTN)...and I love it. however I notice the screen brightness is not as bright as my o2 atom. even with the brightness turned all the way up in the settings. however I noticed that when I press the camera button the screen brightness increases for a second (to the same as my atom). but the when I close the camera the screen dims back again. seeing this lets me know that the screen does have the capabilities to be turned brighter then is allowed through the settings. does anyone know a reg hack or a trick so that I can turn the screen brightness up? does everyone else notice that the screen brightness goes up when the camera button is pressed? or is this a hardware issue? thanks for the help guys!

I've not tried it on Hermes, but VJLumos II takes advantage of the extra brightness that occurs when the camera is enabled, to make a super brite screen. This works on the Magician, and can be enabled on the Universal but not disabled until soft reset (I've not been motivated to finish writing the Universal's version.)
If the Hermes exhibits this same characteristic, VJLumos II might work on it. Give it a go and let me know.

Hi Vijay555 yeah i was actually on your site and ive heard alot about VJLumos II. But I thought it was only compatible with the Magician. Do you think there is any risk of it Hard resteting my 838pro(Hermes)? Anything else i should know before installing it? Does it work 100% correct on the magician? Please let me know!
Thanks!

Works 100% on the Magician, and the active part works on the Universal.
Basically it mimicks the camera and causes it to be activated, causing the extra brightness.
I can't guarantee 100%, but say 99% that it can't hardreset your device (without having the device in front of me I can't say...)
It'll either work or not work, it shouldn't interact with anything else.
I'd be interested to get a Hermes rom dump at some point to see what it's like. It's a great piece of hardware, I'm wondering how to get one now I've jumped ship to the Mio!
V

yeah the hermes is great. Ok well i guess i will be the guinea pig and test it out on my device...haha i hope nothing happens. Ill install it in a few hours and let you know what happens. If i need to remove it will it just uninstall?
By the way is the a reg hack that can do this also?

There's no registry setting I know of that will do this, but there might well be; however, as I said, VJLumos does this by interacting with the hardware in an unexpected way, so it's unlikely to be replicated in the registry.
I think you can run VJLumos in stand alond mode, without installing (which will cause it to be enabled every time you switch on). Just run it in stand alone mode to test it out.

Hi all,
I'll also try with Wizard,should I or not?
Any effect on battery life. I mean is it more than max of hardware brightness

Hi Vijay, what do you mean run it in stand alone mode?

fordcan: I'm sure that it doesn't work on the Wizard, if it did then I would have written VJCandela for it as well. Not right now, and not until I get a wizard in my hands (all you new Hermes guys, if you find yourself with a spare Wizard, I can give it a good home!)
phame: if you just double click on the VJLumosII icon, it'll enable superbrite once. If you click on the -install icon it will try to enable it every run.
Like I said, it's not written fully for WM5 yet, because I never used my Universal as my main phone, and frankly the screen was bright enough. The magician benefited from it, but hopefully any HTC phone that exhibits the curious camera loading/screen brighter thing might benefit from it.
However, for now, as I said, it's not fully debugged for WM5. But test it, and if it works, I'll try to make some time to fix it. The problem is that it will only work the first time, not every time you run it. Hopefully easily fixable.. But it won't do any damage.
I presume it will drain the battery faster, since screen is brighter, but if you use it in bursts or recharge daily, it shouldn't be an issue. I never used my Magician without it, and it was fine after 1 year.

thanx for the reply,
I a bit confused; you are telling "doesn't work on Wizard" and at the same time "any HTC phone that exhibits the curious camera loading/screen brighter thing might benefit from it " Wizard got this..
curiosity kill the cat :wink: Better try and see issue :idea:

fordcan:
Sorry, it might benefit from the technique, not necessarily this version.
Like VJCandela, I have to have a Wizard in my hands to experiment with the camera driver. It'll be easy to write once I've got the device in my hands, but I can't test it.
It shouldn't do any harm, since it'll probably just not be able to find the correct camera driver on the Wizard. But give it a go and tell me if it does anything.
I never knew that the Wizard has this screen brightening effect
V

Absolutely not working.. tells; "Can't load Superbrite Libraries!"
Anyway "Trying times are no time to quit trying"

Ok i downloaded the cab file, copied it to my memory card and executed the file. And it worked perfectly instantly the screen brightness went up. And it didnt seem to be causing any type of slow down or problems.
When i click the camera button i just get an error message which sais "the camera app is already in use". But luckliy no soft reset.
However i couldnt find how to turn it off. It doesnt show up in the list of "running programs"
so far the way i launched it was by just clicking in the icon. Can you please tell me how to do the "-install" thing you were talking about?
and how do i shut it off if i want to use th camera? At the moment i can only do a soft reset for it to turn off.
Thanks!

You should have a bunch of shorcuts installed in yor startmenu.
Launching VJLumosII with parameters -off will disable it, clicking -install will install it so it's run every time it's switched on.
However, I've not tested the -install option on WM5 so let me know if it works appopriately. I'll get around to reweriting it eventually.
V

i tried clicking the short cut to shut it off. But i get an error message saying something about the application being corrupt. So to diable it i still have to soft reset. Im scared to install the app in fears that the remove shortcut may not work
Also ive noticed the battery drains about 30% faster with the app running.
any ideas?

As I've said, it only half works on anything other then the Magician. I'll fix it sometime as a priority - I just got a Hermes, and have to say that the screen is a bit "meh", not as bright as a Mio 701 or Magician. Washed out colours and poorer viewing angle. Superbrite is necessary, not optional
V

I've just switched from a Prophet to Magician. Couldn't stand the slowness of WM5, especially with some big database software I use. The only thing I miss is the Prophet's screen brightness (OK, battery life was great too) so I was really pleased to find vjlumosII. The only downside I've run into is that it adds about 3 seconds to the power up time when I press the power button on my Jam. I've not seen this mentioned elsewhere. Is this a normal effect of the software?

Do you see the slowness on the Magician or the Prophet?
On my Magician I never noticed it.
I just wrote a new kinda app yesterday for low level hacking, and will see if I can apply this to VJLumos. Hopefully some new ish updates coming soon - however, I am using my time well I hope. I'm writing a new website, hence the slow progress on programming.

Vijay,
I've only used vjlumosII on the Magician. The Prophet is the first PDA/phone with a screen that was as bright as I'd want, so I never tried vjlumosII on it.
The delay on my JAM (the 128MB RAM version) is not subtle. It takes a full 3 sec for the phone to come on after you press the power button. The same thing happens if you push any other button to turn on the phone. There doesn't seem to be any delay in the phone coming on if it is awakened by recieving an incoming call. When I turn off vjlumosII the power up delay disappears.
Also the screen brightness initially doesn't come on at maximum. It takes another 2 seconds to boost up.
Thanks.

Just got my XDA Exec - a few Qs

Well, I am typing this message from my new Exec, and I have to say on the whole I am impressed. I have a few questions though:
1) Specs say 1.3Megapixel camera, but I have the option of 2MP mode, is this normal? Is it a software resolution increase?
2) The phone sometimes loses all reception and never reconnects until i turn on flight mode and then off again. Anybody else experience this?
3) Can I get rid of the damned O2 Active part? when i change screen orientation, it takes longer than i expected to redraw the screen. I think this is due to the O2 UI.
4) Finally, there is a button on the side with a lightbulb beside it, what is it supposed to do? mine doesn't appear to do anything...
Allan
allanmb,
1) Had not seen that option. Just took a picture when in 2mp mode. Picture is 1600x1280! Nice find!
2) A number of people have reported problems with the phone. Mine is working fine, as far as I can tell, but look on the forum and TG for more info.
3) O2A - If you look in Programs, you will see an app called Install Type. This allows you to change your installation on-the-fly. Select Basic, and that gives you all the right settings but without the O2a rubbish. There was an addition to this posted on Tekguru, that stops the nag screen from coming up when you restart. Unfortunately I can't connect to TG at the moment, so I can't give you the link.
4) The button with the lightbulb. As far as I know, this is supposed to toggle the screen backlight on\off. I think it only works on battery, though I have to admit that I haven't tried this.
Thanks for the reply. A few additonal comments below:
1) Glad to be of help, the pics look good in 2MP mode too
2) I may have found something by mistake. I have switched my phone band from auto to gsm. So far so good...
3) Excellent, its sooo much faster now! The O2A stuff is quite nice, but it is waaaay too slow. And I bet that is the reason we had to wait an extra few months for the hardware to come out!
4) I found some info in another thread: The button turns the backlight on if it has timed out. It doesnt turn off the backlight tho. A bit weird to have a button just to do this, but hey.

My Phone Is GOING CRAZY HELP!!

So after updating to a couple WM6 ROMS and being happy, my phone starts to act weird, my screen starts to turn white at random times and i have to keep the keyboard slid out slightly to keep the screen from going white. Then after a while it changes again, and now my screen always goes white until i slide the keyboard in and out a couple of times and then slide it back in, but it will only stay normal for a little and my screen will go white again. In hopes to fix this i switched back to my official T-Mobile 2.26 ROM but i am still having the same problem. Can someone please help me fix this, my phone is almost at the brink of not working and i would have to wait about half a year before i can get a new one. Any help will be appreciated.
are you overclocking at all when you are experiencing the problem???
I have heard that overclocking to too high of a speed will cause the phone to go to a white screen..
just a thought
also, if you could, please list all third party apps and the current ROM you are running
.:Nstefanelli:.
Well i was overclocking to 260 using battery status, but i dont do that anymore,i am currently running the T-Mobile 2.26 official ROM, and i have these programs installed:
Wm5torage
Fizz Weather 2
TCPMP 0.81
Pocketdict
If you need some more info you can look at my signature too.

how do u do that ?
killerkhatiby009, you can check if it is a hardware problem by performing a remote control (PC controlling PPC, google for it) and start messing with your phone, see if the PC gives you the same problem.
IF the PC gives a good reading (e.g. no white screen) while the PPC gives you a white face, then it is probably the screen problem (not sure what).
IF both the PC and PPC gives you the white face, it is then either software error (hopefully so), OR internal harware error (e.g you've burned your microprocessor?).
Ok thanks for the help, ill go and try that ppc remote controll thing and report back.
Ok after testing it the PC comes up fine while the Pocket PC comes up white.

Sounds like a hardware problem to me, which may be a result of your constant overclocking. It may also be due to a bad switch in the keyboard slider.
You might want to contact your provider and see if the phone is still under warranty and/or if you can get a replacement.
Well my phone is no longer under warrenty, does anyone know of a way to fix my phone or get a replacement?
Hi,
Can someone tell me how to upgrade my IPL please ?
found my answer. Thanks anyway
I have the EXACT same problem
Ignore my signature - I downgraded back to the latest stock T-Mobile ROM. I see the same problem no matter what ROM I am running.
It is EXACTLY the same as you describe here. I can usually make it stop by pressing the sides together (holding the screen and keyboard slider tighly closed). Once it stops if I set it down and don't touch it it will work fine.
Also when I reboot the splash screen never has the problem - the problem starts as soon as WM boots.
So what did you have to do? Buy a new one? Or were you able to get service or an exchange?
It seems to be the mechanics of the display connector that are causing this. I looked in the service manual and it shows a stiff flat flex-cable connecting the keyboard to the screen, and it seems to me that this cable is the problem - either it is damaged or it is not fully seated on one end or the other.
I considered trying to dissassemble it and clean/reset connecters - for about a nanosecond. But it looks way too fragile and full of hidden little plastic hooks that will break off if you don't release each one in exactly the right way and then it will never go back together again.

FlashLight - anybody knows sth?

In Hermes I loved one feature: possibility of turning on the LEDs (called boldly a flash) with one of Vijay's apps. Of course I could not resist to test in on our (beloved) Rapahael but... Yes, you guessed right: marche pas/does not work/nie działa (choose the one you prefer). Anybody tried to work on this "problem of a person moving often in the dark areas with keys that must be inserted in always-too-small hole in the door"?
Of course you could just go in to camera settings to turn it on or off, it is only 3 or 4 screen taps away...
I mailed the author of the software, and he says that he will try to adapt to software as soon as he has some time, which would be in a few weeks. He says that there are people that already have modified his software to make it compatible with other devices. Anyone that can do this for the TP? I REALLY need that software too.
count me in on that one
i have been looking for it for 2 years now and it still dont look like there is gonna be an app for turning the flashlight on and off
as far as i know it is controlled by the cameradriver
Two years? It's been long available for wizard (vario) and hermes (vario 2). However, in case of my wizard I needed a rom update which included the correct htccamera1.dll (one that exports camera_flashlight method).
On a seperate note. I've been trying to get the flashlight to work on the touch pro, but no luck so far. Seems there is indeed (read it in diamond forums) at least one new parameter to the camera_init method. After debugging the dll it seems there may even be a lot more new parameters to the camera_init.
Anywayz, if I get anything to work I'll let it be known.
Waiting impatiently to test the results amd/or help in the process.
You could always try this:
http://www.artamata.com/pocketlight/
That doesn't work on the Raphael. It doesn't turn on the camera LED.
If you mean to use the screen blanker of that software, I sure hope you looked further, as there are other developers that made free versions, which are even more advanced (i.e. turning up backlight to full capacity at startup). Search the diamond forums for flashlight to find it.
Yay! I've just got it to work.
I'll build a small app for it to make it usable and post it on the forum.

cheers mate ur the best
havent seen it for the vario only app i know off is vjay candela and that didnt work neither does all other applications for the flashlight..
and now i have a new phone and the flashlight application you just made ..
i cant be happier right now .. you made my miserable day a very illuminating one

you should try hTorch 3.2 as well,
which has a very elegant interface:
http://forum.xda-developers.com/showthread.php?t=440405
As I said in another thread; lately I have been using TourchButton in combination with G-Trigger, I'm really pleased with how well it works.
The G-Trigger program runs in the background all the time, so now I just shake my phone a bit and I get light, shake it again and the TorchButton program runs again (thus turning it off).
And in the event the light should somehow accedentaly turn itself on, it will turn off after 60 sec as per the TorchButton code.

Happy with my HTC TP/Raphael!

Hi Guys,
I now own a HTC TP/Raphael for two weeks and am extraordinarely happy with it! I waited about 1.5 years to finally find a machine that mets all my needs and wishes.
I want to thanks all you guys, because I read this forum months before I finally bought the thing and was very pleased with all the info, pro and con, you all posted!
I bought mine in Holland with Tomtom v7 bundled.
Common problems I faced and how I solved them:
1) Problem: Slow GPS Fix (10 min). Solution: Found Quick GPS pre installed on my device, ran it and have a fix now within a cool minute.
2) Problem: HTC picks up or cancels incoming call in trousers pocket. Solution: Installed AnswerDisabler 0.5.1 Thanks to the programmer! It works a treat!
So now I can clear my jacket pockets of the weight of a huge HP iPAQ 4700HX and my compact camera Canon IXUS 850. (The latter I still take with me on occasion, but for the odd picture opportunity, the HTC suffices.)
I'm wowing my friends on a regular basis with this device, showing of the nice TF3D interface and G sensor app's.
Okay, I might still have a small inconvenience left, but I will post that in a separate thread.
Thanks again and keep up all the good work!
Emiel Ratelband?
I too am a happy customer with my Touch Pro.
I faced a few slightly different inconveniences:
1. The Web Browser tab in the TouchFlo does not display the graphics. This is the screen where the YouTube icon. I've update the graphics with GIF files of a few of my more common websites and reduced the size of the images. Works after a power down but not after a reset.
2. Battery performance is still not as good as I was hoping but definitely better then my Dopod C730. I've already done the performance tweaks and this has indeed improved the battery performance. I use the device with push mail for my office email. I also enable 3G and disable Bluetooth.
3. Screen brightness under direct sunlight is bad. Can't do much about that one.
4. The TouchFlo sometimes "hang" with a black screen or frozen home screen. Haven't figured out why yet.
Other than that, I love my new toy.
I am another happy customer and the issue of the battery I dont have actually... I am in Hong Kong and bot the TP at the sole authorized retailer and not a parallel import so therefore my TP is branded which is a pain in the butt. I don’t want to flash the ROM as I’m a newbi at WM stuff so if I screw anything up, I’m dead. Also I don’t know how to get into the registry even if I install Total Commander and stuff… but back to your question….
My beef:
1) I don’t use the TP 3D and I use the standard WM screen. However, ONLY the browser Opera has the auto rotate function unless I slide out the key pad…. How annoying is that? I have found a forced rotate application which is SPB Phone Suite but I don’t want to use this as out of this entire program I only want is the force rotation function… so I’m still searching if there is a app to just force rotate the screen.
3. You can actually, if it is on auto adjust brightness. Turn it off because it toggles between 30-70% which means that you have 30% more brightness if you adjust it yourself with the slider.
@sgsdebruin: No, no Emil Ratelband. (Dutch happy-guru a few years back). Just thought it would be polite to let all the people, who spent time to do this stuff for the community, know that it's appreciated. I know it works for me if others are being appreciative so...
@kelvgoh:
1) No problem for me.
2) Battery performance could be better, yes, but I'll have it on the usb a lot anyway for synchronizing with Outlook at work, so it's not so big of a deal. I'm also thinking that battery life of a device is inversely proportional to the screen resolution.
3) Screen readibility in sunlight. Yeah, that's not so good. The screen of the device is not anti-reflective at all, what makes it really sparkle if you haven't reflections in it, but if you do, then it's bad. (See also some of the Youtube video's of the HTC. In many occasions you can clearly see the camera it's filmed with.)
4) I lucked out there too. No problem.
Fact remains that some HTC TP do have weird problems (1 and 4) and others don't. You can read more of those freak problems on the forum. It looks like the production process is not making consistent devices every time.

Fuze screen problems

Today I used the iGo8 GPS for a little bit just to get onto the freeway. The phone tends to go to sleep, and when that happens, it loses it's GPS signal. Since I was already on the freeway, I know my way around so I just let my phone sleep.
When I got home, I realized the bottom part of the screen, where you can scroll through home, people, messages, etc. is messed up. That part of the screen keeps flashing. AND the GPS screen got burnt into the screen, like how things burn into Plasma Screen TVs when you leave it there for a long time. But it's not a completely burn on, it is like a ghost affect.
I have soft resetted my phone. Doesn't work.
Anyone knows how to fix this problem?
Thanks.
I can post pictures/video if it will help.
Have you tried running igo again and closing it down properly?
Yeah, I closed igo properly. It's not just burnt in the igo screen new. It changes. Now it's the Today page. I can see the "Phone" and "Camera" buttons burnt into the lower part of the screen.
ROM Issue?
What ROM are you using? I always use EnergyROM and its a great ROM but it always does the same thing... i thought my phone was ruined the first time i saw this, but when i flashed to another ROM it all went away, im not sure if certain ROMs use different video drivers or what, but my problem atleast seems to just be with the ROM.
Good Luck!
use a all-black or all-white image(i think all black is betteR) and keep it on to try to reduce the burn it...
ohhh. I am using EnergyRom as well. I will change roms and see what's up.
the all black image seems to be a good idea.
