[REQ] Backlight fading in and out app - Windows Mobile Development and Hacking General

Is there a brave soul out there who could develope an app that makes the back light fade in when the screen turns on, instead of just switching on, and make it fade out, first to the dim level, then off? It would be pretty neat, if there was an app like that.

It works like that automatically on the newer devices(TP, Diamond, HD)
I Don't know how HTC implemented it but it sounds possible on older devices.

Oooh. It would be awesome if this was possible on older devices, like the HTC Vogue. I hope some dev makes this.

There was a thread just like this that I started, and also one that I posted in, basically it is possible through software as when i use android on my Tilt, the backlight fades like you are saying. But not in windows mobile.
Though I dont know much about it I believe the newer devices do this on a hardware side of things. But in our case it should be very well possible.

no sir... it only on the diamond...
my Touch HD does not fade... wehn i press the standby button...

Yeah, I got the idea from Android as well. I thought it was impossible due to hardware limitations, but when it worked on Android, I have gotten very hopeful.

Someone got it working on a certain processor, with the MotoQ smartphones.

Someone tried making an app like that for our phones(Vogue, Kaiser, etc.), but it was too glitchy and incomplete.

Camera Light as Notification LED

Would it be possible to make the camera light flash when an event occurs. For instance, when a call is received, or when you receive a message. I for one tend to put my pda face down on my desk, just in case something falls on it (It also prevents dust from collecting on it, as it's a bugger to clean off) so it would be a novel use for the light. The camera light woul definitely draw attention to the phone, much more than the little orange flashing light that's there atm...
Anyone know of anything which may do the job?

Well I love mine far to much to commit it for scientific research
Why can't all of these little bits of hardware all be accessed in the same way on all devices... It's silly having to access them directly. It's a bit like the sounds and notifications thingy. There are loads of notifications, so why can't we change them all without having to install other programs? Because you can in the full blown windows...
Yes, but on PCs the hardware has to be made hardware compatible, or interfaced by appropriate drivers. On the PPC you're not working to a strict hardware platform, so you get different cameras, different scrollwheels, different audio etc. And that's even just withinHTC.
We're working at a driver level, or even worse, hardware level, and that requires some device specific work.
If it's any consolation, the Hermes and the Universal are much more similar then the Wizard and the Hermes, for example. So perhaps things are moving in the right direction.

Granted the platform differs, however, there should be a method to activate and de-activate the camera flash that's semi universal, I refuse to believe the camera application that comes with the wizard is written specifically for it.

Deflated

Got my new HD from Uk Mobiles. Was really looking forward to it. What a let down. Is this really the phone that is raved about? What does it give me that my Tytn didn't apart from a bigger screen, welcome but not essential, and built in GPS?
It is no faster in real use, the volume is so low when using Tom Tom that it can't be heard (unlike my Tytn which needed turning down and could be used in my old diesel Transit with no problems) and the lag on the GPS is so bad that you need to stop on roundabouts for a cup of tea and a biscuit so that it can catch up and show you which exit to take (if the sound worked I would have known because Jane would have told me).
It only changes orientation automatically in one or two items of software and it came with a rubbish little carry bag instead of the very usable belt holder that came with the Tytn.
Most of the software that is available was available on the Tytn, it seems to be only the extra screen real estate that makes a real difference.
It has no external buttons, something I didn't realise I would miss.
It's just as crap at syncing over bluetooth as the Tytn, I know that's a software issue but it just adds to the frustration and disapointment.
edit: Orange have identified a fault using a flow chart questionaire and have given me a fault code, Uk Mobiles are replacing the phone. If I can't come up with fixes for my issues, or rather the phone's issue my own are to deeply ingrained, before the new one arrives it's up on ebay.
What am I missing? Can it be turned into a usable phone or should I sell it on ebay, seek out a second hand TytnII and accept that I can't handle change?
Volume on mine is too loud actually,
Get HDTweak to enable the louder volume
Orientation can be changed in almost every app.
I use Mobile Magic to manage my Orientation apps
I have also fully tweaked my phone and I love it also coming form a Tytn.
I also miss the hardware buttons and most of all the slide out keyboard but I can now type just as fast on the softboard.
Your right about the speed not being any quicker but I can cope as can the phone.
My advice is if you feel like you say then sell it. however as with all HTC phones they have to be tweaked to get the most out of them.
That's why this place is such a god-send, Without this forum I doubt that many of us would own a HTC device.
Graeme, I know you're pain. When I got mine last November I struggled for a week to get it to sync with my exchange server and I had bluetooth issues as well. The stock rom seemed unstable and slow. I don't have any of those issues anymore and haven't for a long time. May I suggest trying a cooked rom. There are some great chefs in this forum that have refined and tweaked things such that, in my opinion, allow the HD to run the way it was intended...smooth and fast. My HD is solid. My point is, before you put it up on ebay, give one of these roms a look.
I'm sorry to hear you feel this way. I know others feel the same and similar threads have been created. Would recommend sticking with phone and trying to become adjusted to it. Read up opn other threads andpossible use software to improve phone. Plenty available on thjese forums if you search.
No need for another thread is similar ones exist.

Physical keyboard built into flip case for HD2

Hey there guys - how difficult of a task would it be to build a physical keyboard for the HD2, built into a case, connected through USB for the HD2?
I'm looking to the LG Versa for inspiration but have no real experience getting physical keyboards coded to work with OSs..
Was imagining how cool it would be to have the keyboard from the G1 built into a flip case for the HD2...
Is this an extremely lofty goal? Anyone out there with experience in such a matter?
I've looked at BT keyboards, but they are all way too big to be comfortably and logically integrated into a case for the HD2...
Appreciative,
Rod R.
All due respect, why not just buy a phone with a keyboard?
Do you know of any phones with the HD2's specs and screen size that have a physical keyboard that will work with TmoUS?
I came from a G1 and loved it... I love the HD2, but missing the keyboard.
If there is a phone you can recommend with the HD2's specs, screen size, looks, etc, with a physical keyboard, preferably with Android, then I'm all over it... I don't believe it exists.
Cheers-
Rod R.
MyTouch Slide is coming out in June, 3.5 inch screen and 600mhz cpu. Thats the closest to what your asking.

The only way you can connect a keyboard to the hd2 would be through bluetooth. The HD2 does not have a working usb host feature right now. I've seen small bluetooth keypads that are about the same size as the HD2 that you might be able to use... but it has really small keys like on a blackberry. it's more of a thumbboard.

The last I heard (this was back in 2008), Windows Mobile doesn't offer a USB host or SDK.
Since you pointed out that this phone doesn't have one "right now" am I to assume that some WinMo phones do have it or that it is possible to have one for the HD2 in the future?
OP: I have a Dell GM952 that I use on my HD2 when I am home and texting/tweeting a lot. Haven't seen a massive battery drain like I was expecting either.
I know you are asking about HD2-sized bluetooth keyboards, and this is a full-size QWERTY, but I thought you might be interested in hearing that I don't have any problems with it.
Good info!!
The Mytouch slide is nowhere near the coolness factor of the HD2, but thanks for the heads up..
I'll look into the Dell GM952!!

There have been many WinMo devices with USB host functionality... Athena was one of them. There were many others. The HD2 actually has the hardware to support USB host but doesn't provide power to devices connected to it. It just doesn't have the software or drivers.
Cotulla (the one who developed hspl for hd2) was working on a driver that allows usb host functionality, but you would need to provide external power to anything you attached. Theres a thread in the original Leo forum. But cotulla never released the driver as he was still working bugs out, and now it's been over a month since cotulla has signed into xda, so I don't know what happened to him. I hope everything is ok with him.
Also, I hear the USB host drivers are going to be functional in the linux port... so when android is made for the hd2, it should have usb host.(but again, external power is needed)
Check out these bluetooth keypads... you might be able to turn one of these into a "keyboard case"....

Gotcha. I, too came from the G1, and was worried about the lack of physical keyboard, but find I have adapted well to this.
This actually is a great idea, although it'd be kind of akward since, on a decently made, agenda-style pouch, both the keyboard and the device would sit in landscape mode, so, when trying to use the device, you'd be forced to take it out and force it to portrait mode (sure, some apps do sensor-rotate, but for the ones that don't you're screwed).
Still nice to be able to carry around a keyboard for fast typing in a nice, stylized, elegant looking pouch.
HTC's IME, which was surprisingly good on Android, is kind of frustrating to use on this device for some reason.
There's also this thing, which is exactly what you are looking for:

It was discussed in this thread:

It looks very cool but god knows if they ship it anywhere outside HK. Perhaps someone can import that thing and sell it from a more european-usa friendly place.

FROYO on Blackstone - Touch Screen Calibration

Right, since this is such a significant impairment (and some users don't seem to experience it), I decided to create a separate thread for it:
If anyone finds out how to properly CALIBRATE the touchscreen on Froyo on Blackstone, please post it here.
So far, the "msmts_calib=0x395.0x3c9.0x79.0x77" results in random keys etc being pressed on the left hand side of the screen.
Thanks

well, there is a bigger problem as the calibration part ...
in froyo it seems to be, that the calibration willb e done automatical and it is not necc. to do anything extra...
but the module/driver for touchscreen is buggy ...
better for testing is the app dotty (can be downloaded from market).
there you'll see, that if you press via finger middle botton, that it jumps on screen touch to left botton - only sometimes ......and with this bug it is almost not possible to use the phone via fingers ...
my boot paramter for calibration is: msmts_calib=0x395.0x3c9.0x79.0x77
but as told above ... the problem is the touchscreen doesn't work correct if using finger ...
if you use the stylus, then it is working, so i think it is a bug, that if the touchscreen driver is getting multiple zones on touching the display, then something strange happen, and then it add an extra point on the left side, which makes using keyboard (SIP) almost impossible.
the only questions would be: does this bug also happenon 2.1 ?
because it it is there working, then we can try to implement the driver from 2.1.

Slow down...
Slow down guys...
For 99% of users the calibration works fine, you're in the minority experience tolerance issues.
Touchscreens drift over time, and with heat fluctuations (quite dramatic ones only) etc.
You guys are just unlucky and have devices that have clearly drifted by some amount....
Now, there ARE instructions floating around about how to fix calibration issues, but they aren't on the Blackstone thread, they are elsewhere and I can't recall quite where, but they DO exist.
When it comes to used a finger instead of a stylus, here you just have to live with the differences between a resistive and capacitive touchscreen. Resistive is the one used on Blackstone and most other touchscreens older than 18 months old, whilst never devices tend to have capacitive screens.
What's the difference?
Resistive need physical pressure against the screen, but can be highly accurate in ONE position. You can use these screens with or without a stylus, so can be good for handwriting recognition etc.
Capacitive need NO physical pressure against the screen, but are less accurate.
However they can detect multiple presses at the same time in different parts of the screen.
You can't easy use these screens with a normal stylus and so they aren't ideal for handwriting recognition or fine detail work.
When it comes to using your finger on resistive screen, a lot of accuracy is lost... you're just pressing a large area of the screen and the screen can only deduce ONE point under your finger. This can lead to inaccuracy and wrong buttons being pressed with a UI that has tiny icons and controls.
If your touch calibration is ALSO out, then things get worse still.
Now, before any techies get too techy, there ARE some 'smart' techniques for trying to have multi-touch on resistive displays, but we will no go into that here, and they are generally 'hacks' that don't work in all scenarios.
You guys just need to get your displays recalibrated... that should cure 95% of all your problems, and the remaining 5% are just the stuff we all face... like no multitouch, pinch to zoom etc
It's definitely wrong to give the impressions that XDAndroid releases simply don't work correctly with touch screen. That's very misleading indeed.
i too have issues with touch screen accuracy (both 2.1a and 2.2 v1.0)
80% of the presses are fine, but the other 20% xdandroid would place my finger about 1" to the right, slightly down of when i first contact the screen, and then work out where i've actually pressed a fraction of second later, translating it into a swipe etc.
the touchscreen tool in the debug area proves this fact.
WM is perfect.
weirdly, it seems not to occur at all/noticably less using the stylus. maybe something todo with pressure/contact area?
i do think the OP has a valid issue tbh.

Thanks for the info.
First, I didn't mean to mislead anyone. I just noticed increased inquiries about this issue and I wasn't aware of the 99% of users having it perfectly working...is this a fact btw?
Besides, I am aware of the different types of displays but obviously, pinch zoom etc are not exactly the main concern, we are just looking to use the phone with our fingers mate!
I agree - I have been using the phone for many months running WM and I had no issue, whatsoever. I am not much of a techie but you are still referring to the software calibration, correct?
Thanks for sharing some valuable info again. I would love to see those instruction on how to do this calibration as without it and along with much of resentment to use stylus, it pretty much makes the phone running Froyo useless )

But windows mobile typically makes you calibrate your screen when you reflash a ROM, making the calibration specific to your device.
It's also not clear where the calibration info is stored, other than the registry it MAY be stored in E2, or some flash area somewhere. Regardless, it usually forces you to recalibrate (some custom ROMs skip this).
The XDAndroid chaps deemed to 'auto configure' Blackstone calibration for some reason, and this is the most probable reason why folks are having issues.
As for 99%, hummm well, just my releases alone have over 20,000 downloads, and my stuffs one of the lesser used!... yes, some folks have calibration issues, but the majority aren't reporting any... I've maybe seen/heard 20 folks with the issue... that's not too many all in all across all the various releases. AND, some of those guys were also the types of guys saying "this sucks, the battery lasts 2 hours".... as if we didn't all know that ;-)
There was a calibration tool floating around somewhere, plus, those values CAN be edited to suit your device, so there is some home!
Wow, I thought I was one of the only people that had the calibration issue. X_X It's what caused me not to use XDAndroid as much. =(
Anyone have any idea what the calibration tool was? I tried searching calibrate and calibration but no tool was mentioned in the Blackstone droid threads.
PS. I have no idea on how to change the calibration values... =/ When I open up the ts_calibration it shows up as blank. When I open up the startup.txt ("msmts_calib=0x395.0x3c9.0x79.0x77") I do not know exactly what the values affect.
Update:
I tried using the stylus but it currently has the same problem as if I was just using my finger... Does that mean that my touch screen is going out on me? =(
I have a problem too with touch screen calibration.....I guess i'm 1% of users...
im curious as to how maany others have this issue - seems theres a few coming out of the woodwork now
im sure the XDAndroid FAQ or the release thread says the devs are aware of almost all issues so dont bother reporting them (or something to that effect), yet i havent seen anyone mention touchscreen issues upto this thread.
does anyone see a need for a bugtracker for the XDAndroid, or are the forums sufficient? to me, forums seem a bit 'unofficial' with reguard to bugs - maybe an official bug tracker (specific to the android project) would help everyone to see what people are experiencing and numbers involved.
i must say i am only a user, so i dont see or get involved in the development side so maybe this thing already exists in closed circles.
to put it another way, each phone has their own android subforum so it must take the devs alot of time to collate info. bug tracker could be a better way to manage this?
I have the same problem, since 1.6... i touch the screen and is like i touched 1cm outside the screen on the left for 0.001 seconds, so is extremly difficult to type without stylus.
with the stylus is much better but still not good
Ps. i remember the first version of android working on blackstone (1.5 i think) was working good, and the touch screen was fine

I would dig up that version along with calib code in the startup txt file then!
well, i've put the idea forward in the main android subforum here.
it would certainly be useful from a user side perspective to see progress and known issues. fingers crossed
edit: and when did i move to 'Senior member'!!?
I experience similar issues with 2.2, didn't notice it to the same extent in 2.1. When I type on the on screen keyboard, pretty often i get an added button press detected off to the left (about 2 - 3 cm). The problem does occur a lot less when using the stylus instead of the finger.
This is NOT likely to be a calibration problem, as in that case all presses would be off consistently (e.g. always half a centimeter in the wrong direction or something like that).
It looks as if the Touchscreen sends some "incorrect" data that WM filters as too short of a press or whatever and that is affecting some users.
mmm, questionable.
Calibration is as far as I'm concerned done each time, individually with new system (ROM) unless using a saved one from previous attempt install (my Froyo case).
To my understanding of the matter, wrong calibration doesn't necessarily have to mean your display is "shifted" 2cm to the left or so. Simply, it just doesn't work properly i.e. you have the same problem as all other people in this thread.
Maybe reading TheBrilliantMistake's post about different types of screens earlier would help you understand...
after all, we need that calibration tutorial/tip which is allegedly somewhere around here...

ah - finally
now you got it - this is exact the problem what i want to tell everybody ..., and i'm sure, that this happen, because the touch screen driver doesn't calculate correct the position when a bigger range (like touch from a finger) is touched. This doesn't happen, when stylus is used ...
to remove the first 0,1 sec or something ... don't think, that this would help
...on the other hand ... which module is responsible for touch screen ?
Just for a start the background of calibration (it's on security risks with touchscreen based voting machines but the principle is obviously the same) - http://vote.nist.gov/threats/papers/touchscreencalib.pdf
I believe TheBrilliantMistake in this case thought we'd sometimes hit adjacent buttons. But fact is, it always does trigger to the left and in addition to the correct press being detected, so well there's something else to this one.
Guess it will be ironed out eventually as it's a lot less common in 2.1. But it's annoying to the point of making texting a real pain in 2.2.

does it means, that under 2.1 there is no such kind of "touchscreen bug with finger" ?, because then we can take a look to the modules - maybe we can compare the difference to 2.1 ...
I didn't experience it there but I have to admit that I didn't use 2.1 for too long. Maybe it's a speed issue with 2.1 being more optimized and polished then 2.2 which leads to it occuring on a less frequent basis.
Due to the known problems with powersafe modes not being supported yet in XDAndroid I'm currently mostly running WM6.5 but I'm looking forward to the advancements with XDAndroid, great project.
Add 2 more devices to the 1%.
I'm experience the same issue. My friend which has a newer Blackstone than me let me put my XDAndroid mSD card into his phone and there goes the same issue.
Tested with some drawing applications, here is what i experienced:
Just like others stated before most of the times when the bug occurs I get a line starting like 2 cm to the left of my finger (and a little lower) and ending under my finger. It's like I've been dragging my finger across the screen for 2 cm. Sometimes it goes as far as the left side of the screen.
Since this is inconsistent I doubt it's a calibration issue. I must assume it's the driver. But I might be wrong.
Anyway I believe a lot more people than 1% are experiencing the issue but they aren't posting about it since they believe it's a known issue.

N1 keyboard misfires

My keyboard misfires badly intermittenty. I know it's an old issue but I've never found a solution. The delete key inputs Smileys, the l strikes the spacebar...etc.
It does it with better keyboard also. I'm trying Smart keyboardPro now and it's good so far.
My question is, is this a deep software issue or a uncorrectable hardware issue?
thanks

Turn the screen on and off when this happens and it will be fixxed for a while until the stress builds up again.
I always turn the phone completely off and the keybord stops with the problem
Sent from my Nexus One using XDA App
Yeah, as Chopes said, turning the screen off and on works fine for me. Gets really annoying sometimes, I use Swype.
this is a constant problem for me and really the only reason I am considering the Nexus S despite it being a hideously ugly plastic turd.
currently though, the trackball is simply too important for me to lose. here's hoping gingerbread makes it less necessary by making it easier to interact with text via touch
The latest (Korean) radio version supposedly fixes that. I only had the issue a couple times, so I can't confirm.

For me this didn't fix the problems mentioned at all.
While surfing the web I sometimes face them about every 30 minutes and always have to lock/unlock my N1 then to make it working properly again, although I have the newest OTA-update and (Korean) radio fw installed.
Strangely it seems as if these problems would occur less often when holding the screen clean...Don't know if that makes any sense!?
I have an issue where rapidly tapping the delete key selects text... not really sure why the heck that happens.
The only clue I can offer is that it only happens to me when I use one of several wall wart chargers that I have. One of the chargers seems to cause the phone to feel warmer than the others, and once it warms up, the KB goes wild. Removing the battery solves the problem and once plugged back in it doesn't recur till the following night when I plug it back into that particular charger.
Not a big samsung fan.
Is it a dead spot on your phone
I feel for you, this is a well know issue with the low-quality touch sensor panel used on the N1. The best evidence for this is seen with any application that is very touch dependent (like virtual keyboards). If you download any of the multi-touch testing apps in the Market and compare the results with any newer phone, the results are pretty sad. The Galaxy S for example can register 5 individual points at once, the G2/MyTouch 4G can see 4.
The charging/heating/screen going crazy problem is also common place - I run into it at least once a day.
I still love my Nexus, but this kind of craziness makes me think twice about HTC's decisions on parts.
Yes this definitely a major defect for a lot of n1's. I've done numerous swaps behind this issue, and every single one of them has suffered from this defect. As far as features are concerned, the n1 is the best I've had, but because HTC chose not to address the issue, I've decided not to purchase anything manufactured by HTC. Maybe if i only paid a couple hundred for this phone, i wouldnt be as disgruntled, but $600.00 is a lot for a phone with a defective touch panel. I'm so glad Samsung and others are providing better options out there. HTC will not get my money anymore.
