Hello friends.
I am looking for an application for measuring car x and y tilt for offroad uses with 4x4 vehicle. Only one suitable app I found is the Kai's water level with its gyrometer feature,but this is very small and in my case I don't need bubbles,so I want to get a software to do my job,but with much larger indicator,angles and warnings as this... http://www.youtube.com/watch?v=QegwIr4dle8
Is there anybody here,who can mix both functionalities of these softwares for me(cause I am not skilled with C)to one application? Super graphic effects aren't necessary.
Thanks in advance.
Very cool idea. I found this http://sites.google.com/site/srlappsproject/home/on-the-level-app its for android but looks cool.
This is very ideal,but for iPhone

In truth that's not a difficult app to write, however, I think you'll have issues if you are planning on using it on the move, as the sensor only measures the gravity that it perceives, so if you move the phone around, it gets terribly confused as to where "down" is.
I'm guessing you want to know that an incline of over x degrees is likely to cause the vehicle to tip, etc, but if you are bumping over rough ground, then you'll never get an accurate reading anyway IMHO.
Cheers,
Steve.
Well,I know,that the sensor reacts also for acceleration,because normally it measures inertial forces and the result is not depended only on the gravity. Anyway,it should be okay,because I need it for very slow motion of the car in difficult terrain and I want to see,if my tilt angle(especially to side) is in tolerance,because I don't want to flip the car on the roof. Are you skilled with this "easy" programming?
I would be happy to do the graphics for it just tell me what you need.

I wouldn't necessarily say "skilled", but I wrote the Touch Incall Screen Tweak which turns on/off the screen during a call based on the orientation of the phone, so I'm familiar with working with the accelerometer.

Okay,I will prepare demo application tomorrow for PC. I want to have the functionality of the software in video,but with comparable graphics as Kai's bubble level gyrometer(visible horizont). It will be lonely one application of its type on the world,so you can be rich.
Maybe a little something like this. The buttons at the bottom would change color depending on the alarm setting for each angle. You could change that setting by pressing the corresponding button. The numbers in the buttons would give you the actual ° reading.
Just a thought.
Ok, I pulled a stupid moment, there would only be 2 axis, Yaw and Tilt. I was thinking 3D
Also the Waterlevel app found here http://forum.xda-developers.com/showthread.php?t=411550 has the open source files posted with it, may save some time.
For me is enough to have just 2 axis. The front-end angle and side angle. The image posted before is quiet perfect,but we should have 4 buttons for X-warning,X-max,Y-warning-Y-max,when I hit one of them,I will be able to adjust it. Of course some notifications for these warnings are welcomed as well as angle value visible on the screen all the time.
Next thing what is also welcomed is the power-on ability to prevent auto-dim/off the display. All the things should be visible from the driver's place,when the phone is fixed on the dashboard,so the fonts should be big enough and of course the calibration function to be present.
With this picture you have saved me lot of time spended with programming the PC demo-now isn't needed,because all features are explained.
Anyway,thank you for your help and willingness.
Something more like this? Then pressing the X or Y button would take you to a setup page that you could set warning sounds for yellow or red and you could also set degrees for the setpoints of yellow warning and red warning for each axis.
Quiet perfect!
Can you enlarge the degree fonts and locate them to the bottom corners nearby the circle? Also the labels "Actual" are not necessary. Into the top corners maybe you can locate Calibration button and options/exit(if it will be fullscreened). The warning sounds is also not bad idea...
Like this?
Absolutely perfect!!!
Well done mate.
Now just make it working and it will be super. Are you able to make it alive?
Sorry I do not have that talent, wish I did.
Oh,what a shame. I'll try to take some developers here...
I think this needs moved to the developers thread.
Please, make this dream come true! I'm looking for this kind of software too!
Does anyone experience a "white shadow" problem on n1's screen?
when i read a document, i notice the margin area is not purely white, but there's "shadow" of text on the right
is this a amoled limitation of is it just me?
I will try to take photo if the explanation is not clear enough
another issue is that i've always found the n1's screen color to have a red hue
same for this, is it just me or do you have similar experiences?
Hey, no red hue but i do sometimes have a 'white shadow effect' which i notice looking at text, such as reading an email [not 100% sure if this is same problem as yours tho].
i was worried that this might be a problem with the screen but its just a fingerprint issue - all you need to do is wipe the screen!!
the finger prints left on the screen were what caused my white shadow, wipe the screen clean and all the text is evenly black.
magic
I have also seen this phenomenon, specifically in the web browser when there is a white background with back text. It doesn't happen all the time, but its fairly visable when it does. Perhaps this is a defective amoled screen issue? Or maybe just amoled screen artifacts.... not sure. Anyone else seen this?
Also this isn't a fingerprint issue, happens on perfectly clean screen.
I have the odd ghost shadows when reading black text on a white background too.

I see this too. I just chalked it up to a byproduct of AMOLED screens or something. Doesn't really bother me and I don't really notice it that much either.

hmm that's strange because i do sometimes have exactly the same problem and can see the problem disappear as i wipe the screen. From my limited knowledge about amoled screens it seems unlikely that the pixels could be experiencing some sort of 'come and go' problem such as this. If someone could put up a picture...
Well for the record this is a very minor issue, I like my N1 a lot, its hardly noticeable. However I am interested in investigating it, and attempting to take pictures of the effect was well, less then fruitful.
It turns out my digital camera doesn't take pictures up close that well, its actually pretty terrible. I was trying to get a screen shot app to try to capture it but the ones on the market are only for root users, and I haven't made the plunge into root, yet.

I have this problem and it's very off-putting.
Does anyone know if it's theoretically possible to calibrate the screen à la a computer monitor to reduce this reddish casting? In greyscale photos all shades have a very noticeable pink tone (not photos taken by the phone's camera).
I'm giving this thread a kick, because I also experience this 'problem' of having (faint but clearly visible) ghost lines or 'white shadow' when viewing small text/objects (Nexus One), especially noticeable in the browser. The weird thing is, it completely disappears when switching to landscape mode. Turning the brightness down worsens the phenomenon.
It is also reported at Google's Android support, sadly I can't report the link because of my newbie restrictions I also found one report of the Desire having this problem.
I would ask felow Nexus owners if they want to turn down their brightness and report if they also see this ghosting in portrait view (i.e. when viewing an article on nytimes.com fully zoomed out), so we can conclude if this is an insoluble AMOLED related issue or an actual screen defect of your phone (RMA/waranty-issue).
I have the text ghost image on white background. I thought it was software issue, but since it disappears in landscape view that might mean its a limitation of the pentile sub pixel layout.
I think this should explain it. It's not really the AMOLED, but how the "pixels" are actually laid out.
arstechnica.com/gadgets/news/2010/03/secrets-of-the-nexus-ones-screen-science-color-and-hacks.ars
I read that this issue doesn't occur in the old Dolphin browser. I don't have my phone with me right now. Can someone try it? I doubt it has anything to do with the pentile subpixel arrangement. I mean if the part of the screen is supposed to be white, the pixel should display white, not grey. Probably a software issue, IMO.
I just checked, shadows on both. It's a screen thing.
My bad. You weren't using the Dolphin HD browser, were you?
Thank for your replies I don't think it is the browser though, the same problem persists in Gmail, Adobe PDF Reader and Documents togo, I suggest you use one of these applications to look at small text on low brightness. It might be a little more noticeable in de browser, but looks like it isn't a pure software issue. Can you confirm this finding?
@voiceunebunu: yes, I've read that, but that article concentrates on text fuzziness etc. because of the PenTile arrangement, but does not mention this 'ghosting-like' effect.
Of course this isn't such a 'big deal': I would rather have my screen calibrated so it doesn't show up al reddish and get a better screen view in daylight, but hey, I knew about those problems before I bought the Nexus, but this one seams to be very sparsely documented on the internet.
This effect reminds me of the first, monochrome LCD-displays, which also had this problem (only 100x times worse), especially if they grew older.
Possible work around?
Hi everyone,
I've found a work around for this!
Cyanogen 6 has a feature called "Render effect" and basically, there are options to change what and how colours are displayed.
The last three "calibrated" seem to be for the Nexus specifically. I've used all three and the "calibrated" and "calibrated (cool)" are my favourite. Both slightly change the colour output.
There is a slight yellow tint over whites. For my screen the ghost lines are greatly reduced (it used to be visible with normal size text and exceptionally bad when zoomed out). Now its only slightly visible when zoomed out!
Hope that helps!
If you think your screen is not uniform, then you know the way it is not uniform. If you haven't realized such thing, please leave this thread for your sanity :cyclops:
UPDATE:
I have done some research and experiments and came up with this solution. If you suffer from uniformity problems, this might be useful. If you are a developer, please consider building around this idea!
Aim :
To make our screen look perfectly uniform without any tint/temperature problems.
What you need:
Download these from play store:
-Screen Filter
-Gradient Wallpaper
Also on your computer [optional , for fine-tuning] :
-Adobe photoshop
How to
1) Open white/gray solid images to observe your uniformity issues. Take a pen and write down, or even make a simple drawing ( eg. left edge is more yellow and right edge is more blue)
2) Launch gradient wallpaper app. Look at your notes and make a gradient which is exactly the negative of your initial tint (eg. left edge is more blue and right edge is more yellow). Save it.
3) Launch screen filter app. Select the gradient image you saved and load it as a filter. Increase the transparency and calibrate it to your liking.
4) (optional) Use Photoshop for much more flexibility with places of gradients/ shapes etc.

Hello everyone,
Nexus 4 is an awesome phone with minor imperfections. One of them is washed out colors which is fixed by many custom kernels.
The other imperfection is light bleeding, which is a hardware issue. However this and similar issues with hardware causes non-uniformity (or unevenness) across the display specially if it is held horizontally on a white/gray backgrounds.
I have used 10-15 different handled device with ips displays and %80 of them had a visible non-uniformity. Some of us might be totally fine with it while some of us like myself might want better calibration.
HERE IS THE REQUEST:
I have tried fauxdisplay/kernel for a week and I can customize my screen pretty much however I want. The problem is this kernel/app applies the rules for all of the pixels. It would me awesome if we could have 'local' calibrations. (people who use photoshop should be familiar with adjustment brush that changes properties of chosen area).
Tell me what you think about this.

To fix non uniformities across the screen . For IPS screens, when you tilt left you willsee aa yellow tint on the screen, when you tilt right you will see a blue one. If you are looking directly without tilting, right side will be bluer than left side (like a gradient most visible with gray) To fix this, we can tell our kernel to render left side little bit bluer to reduce the gradient effect.
Hope this is explanatory.

i get what you mean, but im sure its a LOT more work than just that..
on another note, i read that the optimus g rom on the nexus makes the screen look absolutely amazing - im waiting till someone ports the settings for that onto our phone and hope that this calibration issue ends there.. too much time is being wasted on this (for good measure, yes. but still)

You are asking too much.
Yes you are. LCD screens cannot have regional calibration.

I don't know how current calibrating is done, so I'd be happy if some developer can help me out.
There are possiblities:
software filtering -> gpu-> driver-> screen (slow)
gpu-> graphic matrix-> software calibration -> driver-> screen (fast)
gpu-> graphic matrix-> driver-> calibration within driver with given values -> screen (fastest)
if it is the first one, it can easily be done. You can choose what to do to any individual pixel. For example, It is done when there are pop-up windows. While pop-up is bright and visible, remaining area is darkened/grayed with some software processing. So with root access, a program might make sure that some area of the screen is always dimmer, brighter or more saturated than other, while it is running on background. (like a filter that is always on top. This for sure can be done: look at many apps that you can slide from left anywhere within android and some menu pops up. What if instead of a menu %85 transparent and blue [to fix yellowing] solid color stays there?)
If it is second one, well, then it is hard as it needs a lot of C programming- testing. But it will be faster than first option.

VIEWER DISCRETION ADVISED
Bring the Brightness level down to minimum visible brightness (Preferably when viewing Near Grayscale); even in a well-lit room, or preferably dark setting, you will notice how Samsung managed to hide the Mura Effect on their latest iteration of AMOLED Panels. Some will see notice the predisposing lines, blobs, banding, and two-tone (or even more) gradients, which expresses the true organic nature of AMOLED Panels (Discussed as far back as the original Galaxy S phone).
Now beware, the Mura Effect is normal and does not make your screen or device defective.
Thanks to Samsung's preset for low Brightness levels implemented on the Galaxy S4, S5, Note3, and Note 4, and newer devices (can only be modified via third-party apps), its really hard to make out the Mura Effect on the newer models. Black color is Black, and Samsung's software mod forces no voltage to be fed to the AMOLED Panel when black is displayed, thus the pixels are literally turned off.
I've seen some users post pictures of the smearing (deep purple and pink tint) at "Normal" lower brightness levels (within Samsung's preset levels), which should be taken into account; I suggest them to exchange their devices or replace their displays until they get something better their eyes can be content with.
Every Note 4 and AMOLED device has these anomalies, however, the degree to which the anomalies are visible will vary from device to device. Some will be unable to make out the anomalies thanks to the nature of their displays (Warmer-toned or Cooler toned displays), and should be grateful and move on. If the anomalies are too obvious, I would suggest replace the screen, or live with it and accept AMOLED at its true best.
Downloaded the app and after messing around for a bit I can say that I am unable to make out the anomalies.
The screen quickly turns to black after messing around for a bit. It's good to know that Samsung has made "some" progress in alleviating some of the concerns most previous Galaxy device owners had particularly pertaining to AMOLED displays. However, we all are still far from seeing all AMOLED displays equal and consistent with one another. Some favor warmer colors whereas others favor cooler colors, and some in-between, thus variances will be prevalent until a final solution comes into play.

I want to make a wallpaper specific for the OP7 Pro which has a border that follows the outline of the screen. The problem I'm facing is that I don't know exactly where the screen ends and where it begins at the corner, and it would be extremely tedious to find this out manually. I want something similar to what people did for the s10 hole punch (https://icdn6.digitaltrends.com/image/creative-uses-of-s10-camera-720x720.jpg), except with the corners instead.
Has anyone drawn out exactly which pixels are on and which are off? Here is a crude drawing of exactly what I mean: https://i.imgur.com/09qwSZg.png
