DEV Request - Android Software Development

I have a request if someone could make such a program (or point me to one that already exists)
I "think" what I want is pretty simple (I hope)
all I want is a black on white or white on black (toggleable day/night automatically) landscape
so daytime would be MAX screen brightness white with black letters. night time would be minimum screen brightness black with white letters (all on its own use approximate night/day times or use light sensor if available)
I would like live lat and long coords and my speed and direction of travel. (from gps not compass)
large letters fill the screen.
No internet (phone won't even be active) and one last thing.
when external power applied turn on and stay on (auto load on boot if phone off) it should run as service and keep itself running restarting if its not running.
when external power is removed put phone to deepest sleep state.
So you have context here is why I wish for this.
I run a "dash cam" its fun I like camera's and I get some "neat stuff" every now and then.
I really like the new ones that embed lat long and speed right in the video with the time and date.
alas the prices goes from $74 to $125 for a nice high def unit to over $300 if you want that last feature ouch.
so I got to thinking. what if I placed a droid phone on my dash so the camera could "SEE" it (its 720p and the new one will be 1080p so it will be readable)
the trick is making it transparent in use. IE automatic.
turn on when I start the car turn off when I stop the car (engine off ie no power) to preserve battery. most droids screen off with no radio's active can go several days between charges)
any chance this is something that could be made pretty easily? or maybe already exists?

Burnt in images on LCD?!!

It appears that I can see - very faintly, burnt in images of the today screen Icons on my two week old XDA mini S.....
They are most noticeable when the phone dialler is selected.
WTF - on a two week old LCD?
Si.
Oh bugger,
Now I think that I'm seeing things - is it possibly that in certain apps (phone dialler) and Comm manager - that you can see semi transparent images of the today screen icons and date...?
Si.
nope - those applications don't use transparency over the current theme
for those wondering - yes, LCDs *can* 'burn in', except that it's not a burn-in, but a charge persisting.
I had it on my laptop after leaving it closed (but on) for about a month to record shows while I was abroad.
When I got back, the TV recording app's outlines were clearly visible. I was quite pissed, as I wrongly assumed that LCDs don't burn in. ( I also wrongly assumed that closing the lid would turn the screen off; it doesn't, only turns the backlight off - stupid design* )
Did some searching on Google, and the two common options to fix it are:
1. display a full white image for a while (hours)
2. turn the display off for a while (hours).
I did the first - cleared up most of it. Did the second (powered the laptop down), and that got rid of it all.
So maybe that will fix it for you as well.
* the PPC has the same problem, really. When the backlight turns off, the LCD is still on; so you're still vulnerable to this persistent charge issue. There's a lot of freeware apps out there that allow you to turn the screen entirely off (note that this turns the touchpanel off as well) - might be a good idea to pick up.
It does seem to be some form of burn in - left overnight last night it has more or less goes away - but I'm sure it will return towards the end of the day.
Si.
I've got this on my wizard too. Last night I left it charging whilst the games folder was open (backlight/power never set to go off on external power), I now see a negative image of my games icons on dark backgrounds. Will try some of the suggestions mentioned and hope for the best!!
I've changed the backlight/power settings now though :evil:

Screen burn in

I was playing a game last night when I have noticed that where my baterry icon and clock is, the screen is a bit grey. Now I have been reading on this forum a lot about amiled burn in but how is it posible to have it that fast?
I mean I have this phone for like 7 months and I allredy see this burn in effect.
Is it normal to have it that fast?

7 moths is more than enough for burn-in...
it begins in 3 months.
should consider yourself lucky if you got it in 7 months.
a word of advice, just ignore it.
don't take it as a big deal or you will just be annoyed all the time lol

Well even though its understandable that the pixels there will wear out eventually being always shinning
I believe its more susceptible for having the screen ON with a static image which includes browsing, google reader, etc meaning all apps that have the status bar ( not fullscreen mode) for few hours (not minutes)
Also OP there is a slight memory effect in my opinion on these screens, means that when you switch from status bar to non status bar screen you can notice it there (grey background mostly).
To be honest, it is very very hard to notice that there. The only problem is I have been planing to use this phone for at least 3 years.(I realy like this phone), but if the burn in goes so fast I won't think it is possible.
I wonder how much a screen cost. Doea eny of you know?
Sent from my GT-I9000 using XDA App
One way to reduce the chance of burn-in is to reduce brightness, and avoid static images on screen. In Launcher Pro I disable the status bar for this reason.
I've had my Galaxy S for about ten months now, and still no sign of the screen burn.
I haave put my brightnes on automatic.
I won't disable that bar because it is to practical. If there could be a way to auto hide it somehow.
Btw: thnx all for the tips and for the fast answers.
Also sorry for the writeing mistakes to.

My SGS is 5 months old now and i never put brightness to automatic but 35-50% and still there is no such sign...
I have it since 2 months after purchasing, Display ist always auto-dimmed.
On the picture u can see the clock and some of the battery indicator.
I have pretty heavy notification bar burn out on my Galaxy S after 5 months of use. I'm now using the Launcher Pro hide notification bar on the home screen settings, however the damage has already been done.
I also don't think that the damage arises from the home screens since we spend more time in apps and browsing then in the actual home screens.
Google prohibits hiding the notification bar while your in an app for some reason. They claim that the notification bar is integral and essential to the android OS that's why devs can't simply hide it or remove it from their apps. It's a shame and there was a thread started on google code about AMOLED screens and the Android Notification bar causing burn out.
Check it out here:
http://code.google.com/p/android/issues/detail?id=9063
The request to hide the notification bar was denied by Google.
I just checked it again by *#0*# and then click blue and i can see "AM" visible @ upper right corner & some shades where there is battery icon. It is not prominent and only showing over blue background but still it is annoying....
Is there a way to fix it?

AM would suggest you use your phone in the morning more then the evening right? I mean if I would get a burn in it would be a combination of PM and AM (oh I use 24h but just hypothetically)
So either you really use your phone more in the morning OR you left your phone on for a longer period when it was AM time OR what you see is not a burn in, just a "slight" memory effect that could wear off (doubt that). However I would go for that second option, that means leaving the screen on while AM :/
There is no way to fix it. Fixing it would mean to let the other pixels wear out whilst the AM space would be saved. On a plasma/lcd (PC/TV) screen you could do that and I bet the first one who does some APP like this for android will make money from it. But to actually decrease life of the other pixels just to have it even would make your screen loose color etc etc etc. And imagine to wear out the WHOLE screen just to hide the AM
Dont know if there is a way to "infuse" life into the aging pixels. Would be awesome.
The thread about hiding the bar. I think google should give in and let us make it hide able. However I think a better approach would be to acknowledge this a manufacturing defect of amoled screens and for Samsung make way of prolong the life. Something like they have on plasma via pixel shift/double pixels (but no all active like on the next gen of Amoleds) etc (wont help the burn in in long time, but will for sure prolong the life )
It is not just samsung. Nexus one has the same problm with the screen from what i know.
A good program to try and fix the problem is the jscreenfix that is in the market( that is if it is a 'memory' problem). and also ffor others to check if they have wear out problems see: "dead pixel test'

I wouldn't call this a defect really.
OLED is a new generation technology and thus, it has many disadvantages as well as advantages.
I'm sure it will get improved in no time.
People who bought the phone should have really researched before making up their mind

There must be some sort of memory effect adding to this, since on mine, when I notice the problem, I can virtually read the current time! The hours are clearest, and the minutes more blurred as you would expect... but this and the even clearer AM / PM part suggests that part of what is seen is the memory of what has been show recently. Note, I'm not saying there isn't permanent damage too, as I'm certain there is, but I haven't figured out how long the memory effect lasts for, and therefore a suitable means of removing that from the equation to see what is permanent damage.
If you could leave the screen off for (say 12 hours? or maybe longer?), and then get the device to wake-up straight into a full screen coloured graphic (without showing the status bar even briefly), you could be more sure what you were seeing was the permanent state of burn-in. Does such a testing app exist, or could one be created?
Mike
I think it is PM, not sure as P or A is not clear but M is easily visible... And what is this Memory effect? Any solution for memory effect?
Burn-in would be permanent damage to the screen. It would be caused by those pixels being used more and "wearing out" quicker, and would be visible as those pixels being degraded by always displaying less intensely than those around them. Hence being visible as a ghost image of the signal strength, battery meter, time, AM / PM etc.
Memory effect (assuming it really does exist - as I suspect) would appear to be the same thing, but only on a temporary basis. i.e when the time and signal strength meter etc. has been displayed for a while at the top of the screen, and you shift to full page of a suitable colour, you would still faintly see the time still in that corner. However how visible it was would depend on how long you'd recently had the screen on for, how brightly, and how recently ago those screen pixels had been used.
The main difference between this and burn-in would be that leaving the device/screen off for while would reduce how visible the ghosting was.
So:
If what we were seeing was only memory effect and no burn-in, then leaving the device off for a while would cure it completely.
If what we were seeing was only burn-in, then there would be no difference based on recent usage... the ghosting would remain at least the same, and in fact slowly get worse each week or month.
If, as I suspect, both have an effect, then there is slowly increasing permanent damage occurring, but also, it will look even worse when the screen has just been used brightly. Leaving the screen off, would reduce a proportion of the damage.
Since I personally mostly use the screen at minimum brightness (and even have it extra dim at night using "screen filter" app set to 10-15%!), mine does definitely have some permanent damage, but might have a lower proportion compared to someone who uses the screen on full brightness all the time. So using the time as an example, I can see the current hour clearest, and if the screen has been off a while, my ghosting is quite dim and blurred (but still visible).
Someone who has more major damage, might not be able to see the difference between memory effect, and burn-in, as their burn-in would be too prominent.
First time a new phone is used, it shouldn't have ANY burn-in (unless factory testing left some), but would still display some memory effect.
Over time, the permanent burn-in would increase to the point where it was ultimately FAR stronger than any memory effect. In between these two extremes, is where I suspect most of our devices sit, except for the heaviest users!
This is my experience and hunch, but I haven't been able to definitively prove it.
Oh, one final difference between memory and burn-in. Memory effect will be overall crisper and influenced by the most recent usage ("A" or "P" will show more strongly based on which was used most recently.. and hour might be crisper than minutes), whereas burn-in will always be more blurred in areas that change (i.e. all time will be very blurred) and only the most permanent features will be crisp (i.e "M" in AM/PM will be crisp).
Be good to hear from others if they can prove that they get a mix of both types of ghosting, and if we can get an idea for how long the memory effect lasts.
Ironically, one good place I can see the ghosting is on the light brown splash screen for the XDA app!
Ideas for testing:
Leave screen off for a while (longer is better - maybe overnight?). Turn on, and immediately open the XDA app, and see the level of ghosting in the top corner. Note how blurred the hours are, the minutes are, the A / P is, and the M is. etc
Then use the phone for an hour solid, and test again, and check for the same blurriness.
After that second test, if the ghosting is overall more prominent, and you see the current hour and the A or P particularly more clearly than before, then you have just proved you have a mix of memory effect and burn-in.
I expect there to be a range of answers depending on how old the unit is, and how well used it has been (most used screen brightness level etc), so when reporting back, please include than info.

I meant Samsung as a Amoled screen producer not just a smartphone one . Oh really jscreenfix is in the market cool I have bought from them the java version (for PC and TV) longer ago

Sorry for use of stronger words. But this is BS the last part about my researching. I should have researched into what I am buying to? Its not a car or a flat to spend hours on forums searching for every little bug it can have. Also in the time most ppl was buying it. No one knew about this. I dont see any warning on Samsung manuals and etc. I am a consumer and not a researcher. Every plasma tv has a warning the lack of amoled warning is NOT my fault. Thus once I see it I will make my warranty claim
But yes that it will improve
Just saw this thread n wondered if some might actually benefit from this :
Its zsjpj's framework-res. It completely disables the status bar, so you won't have it anywhere in the rom.
Just push to phone as framework-res.apk and reboot.
Link
Use at own risk and only flash if ur familiar with adb. Hmm it worked once, now it doesnt.
Gonna give editing another shot 2moro. U can give it a shot but make sure u back ur framework-res to restore after.
hey
after reading this thread i want to test my samsung , which is 6 months old , too. Red and Green display was okay, i dont noticed anything. But with blue i got the same problem like all of you. i see something like 18.xx o clock... sucks but you have to look hard to see it.
But i dont give a **** ;D

For those who have a perfect display! (but also for others)

Hello everyone,
I would like who claims to have a perfect display (as well as all the others) to Try this test:
- Completely dark room and eyes accustomed to the darkness for a few minutes
- Completely black screen (like the one in the test screen by typing * # * # 0, but also any settings menu screen that has not written)
- Minimum brightness (but can be seen even at maximum brightness).
If there are, you should see black spots darker than the background black.
I have them and at night are quite annoying.
I need to figure out if it is a problem of all devices or only of some (in this case tomorrow i will apply for replacement).
Please, you who are reading now, don't leave without doing this little test, it only takes 5 minutes
Thanks: D
Are you nuts? While this may be new to you, there's a 200+ thread already going on this that was started in May. We don't need another 200 pages of "yes it is," "no it isn't." The short answer is yes, there's banding on the 1/4 left side of the display but for most people it can only be seen in a dark room, at 10% brightness, on a grey background, and by taking a pic of the phone. It's been that way since the phone launched and at this point choices are: 1) live with it, 2) return or sell the phone.

Apparently some don't have this issue, as you can see in the first listed thread. Difficult to confirm or not of course, I know mine does have smears/smudges/lines and no it is not grease.
@Barry don't think he is talking about the yellowish tint.
You read this on another thread and started a new one?
I saw the exact same thing on a post yesterday..

Dude, If I may :
before asking us to show the perfect screen (which does not exist actually), please consults an eye specialist and then, come back to XDA.

If you can ever see what you describe under normal use then it is a problem. If you can't see it under normal conditions then you are simply looking for problems and it's nothing to worry about. It's just what SAMOLED screens look like when they're "off", but not off.
I see this every day when I go to bed as my phone is also used as a night clock.
I have the font set to a very low brightness font, except for me I see lighter splotches on an otherwise black background.
I went through 4 SGS2's trying to find one that didn't have it. They all did. Bad batch I guess.
It wasn't a major deal for me so I just live with it.
It's a shame but meh. otherwise this phone is fantastic.

[Q] Nook color screen unresponsive at bottom.

Hello all,
I've recently purchased my first android device and wow is it cool. I've installed several different ROM's on it (CM7 253, Cm7.1, CM9, Cm7.2). What I've noticed is that the bottom has some issues that may hardware issues.
When I'm in a draw program I cannot draw fluidly near the bottom near the N button. Also when I use the pointer control utility in settings (forgot the name) it is nice an fluid for all of the screen EXCEPT on the side where the N button is. It will seems to get sporadic and will make contact, and not and I'll get dots and dashes instead of a nice fluid line. The soft buttons work fine but require more of a firm push when position in portrait mode.
I'm thinking hardware? This is on a refurbished nook BTW.
I can't get to the device as it's under the tree (for my wife).
Can someone test this and tell me if yours can create a fluid line drawing near the edge where the N button is?
Thanks,
Zack
I bought 9 NCs as christmas presents this year, I had to return 3 of the due to hardware problems (Thankfully I tested all of them the day I got them).
One of the ones I returned had poor touch sensitivity on the bottom of the screen which got progressively worse over a few minutes of use. I had to retype several letters when I was putting in the wifi password then it went into standby and I couldn't unlock the lock screen because it wasn't detecting my swipe. It would just jiggle a little. By the time I took it to B&N it wouldn't even jiggle. You'll have to send it back to a place in Reno but going into B&N will save you some time on the phone.
The other 2 had busted wifi (no signal even in B&N) and a sticky power button (every couple of times you tapped it it would stick and turn the device off). There's also a few with blue tinted screens but I didn't want to return those and play refurb roulette again.
Oh, and I just did some drawing in canvas (the notion ink app) and other than having difficulty drawing a straight line my nook works just fine along all the edges.
Wife got the tablet today and loves it. I was just mucking around with it and found the nook screen recalibrator and that seemed to completely solve my problem! Whatever isin that magic potion is great.
yeah, there can sometimes me issues with the digitizer that are almost universally fixed by screen recalibration.

Droid X dedicated car touch screen

Im looking to fully set up my old Droid X phone as a dedicated car interface, for the usual, music, gps, car cam.
I do not plan to use the dock, as i dont plan to spend any additional money on this project, I just want to re-purpose my old droid. I used the base of an old Eye toy (ps3 cam) and put some holes in the battery cover of my droid, then used small screws to mount to base (has swivel and can adjust up and down). Works great (can screw to dash when I need to or glue). I can easy of course unscrew it and use it with normal dock if I get one, but it works good so far.
Im currently using an older version of liquidsmooth, which i removed many of the apps I dont need, and added some I wanted (offline maps, car dock app). I also set it up to wake on power, and to keep screen on while charging. When it stops charging (i turn vehicle off) the screen turns off and after 5 secs it enters sleep mode.
I was wondering which rom you would choose to use for such a project and what you would do to save on power.
Also any suggestions for apps (offline only) would be good. Ill post some pics soon.
