Screen sensivity problem solved!!!!

[Guest kordi]

Ok guys,

I've written a similar topic on our local Polish forum and everyone seems to be very fond of my very simple yet very effective solution....

Some of you might have experienced problems with screen accuaracy and sensivity in Omnia. I've seen seen ppl (including myself) complaining that Omnia's screen is very insesitive and inaccurate ... and I have found the culprit B). Most of these problems are due to bad screen calibration. This issue is related to Omnia only and with other devices it does not exist (at least with the ones I've had so far).

Omnia's touch screen is covered with and extra layer that is soupoused to protect the screen. This in turn causes makes that the touch layer is about 1 or 2 mm away from the layer that you actually touch with the stylus. This little fact causes that when you change the angle at which you look at the screen, you shift your perspective and you might tap exactly the same spot but from a different angle it will seems as another spot on the touch layer. In turn, most of us badly calibrated the device and therefore the screen seemed as less sensitive and inaccurate... In order to fix it, you have to calibrate the screen properly... This is very simple when you take all these factors into account. You just have to look at the screen properly from the distance. Here is what you have to do:

1. Put the phone on the table so it is paralel to the ground (just do it)

2. Get your eyes above the screen but from a distance at 30-40 cm (this is very important)

3. Enter screen alignment menu

4. Use some sharp object to calibrate and not the stylus

5. Calibrate

That's it.

You will be suprised how this little trick will get your screen to behave better B).

Can I use a pin, is that sharp, how hard should I press, should I press herd enough to make a hole in the screen or so the pin comes out the other side of the phone. B)

You can use your common sense B)

I don't think this improve the screen sensitivity. Actually, don't do anything. That MAYBE feel better if you have a bad calibration, not bat sensitivity... It's not the same.

Oi, why dont you give Kordi some time to test and give feedback or try it yourself as you are clearly not stating any facts!

[Guest meabigbaldguy]

Hey, it worked for me! I never really had a problem with my sensitivity but I can certainly say that doing a Kordi cal has made the screen much more responsive to accurate finger taps. When I cal'd, I used my finger nail because that is what I use anyway.

Great observation, Kordi!

I really don't understand why but it seems to work better!!

Thanks for sharing this trick kordi!

PS : Since this calibration method is quite annoying, does somebody knows if it can be backed up in some way for restoring it in future after a hard reset? Maybe a .reg file can be created?

So there is almost dozen ppl in here:

http://pdaclub.pl/forum/index.php?topic=115436.0 (you have to believe me, as you will probably not understand a word B) )

That claim it works ... So either we all have one big group halucination or it does work B). And yes it improves sensivity or rather the impression of sensivity. The way I see it is this: (and I have no actaul proof of it... I a simply rationalize and use common sense - this might be total bollocks).

Let's say your screen was poorly calibrated due to the factors I've described. Now you want to tap a link to some site on the screen. You tap at it but actually according to the phone's sensors (as they are badly calibrated) the link is 1 mm away from the place that you tapped. On every other phone, if calibrated this way nothing would happen. I mean completely nothing.... But on Omnia there is this protevtive layer above the touch layer. So if you apply a little pressure to this layer it will dent. If you apply even more pressure it will dent even more and the diameter of the dent would increase. At certain poin the diameter of the dent is big enough so it connects your tappping as tapping of the link that you desired .... In other words good calbration indirectly might improove screen sensivity.

Hey! Never had big problems with sensitivity, but this works even better! Thanks for the "kordi method" B)

Another thing - much better known than this method - is to touch the screen while aligning only very soft.

B) geez it friggin works!

i wonder how you calibrated before (really i don't try to mock the thread starter, but i just don't understand how these people calibrated before his post), i hope you didn't f*ck up your screen with a needle or something like that B)

[Guest invd]

Before I used the stylus, this seems the normal way to me. Now I used the tip of a pencil and touched the surface very soft. Works.

Me ... I held the device in my hand and tried to do it with a stylus as I always did on any other device. On Omnia this only made me frustrated.... I tried to do it like 10 times like that and every freaking time something was wrong. I also didn't understand why this is so as I never had problems while calibrating the screen. It was due to the fact that while holding in hand the angle I looked at the screen was not correct. On other devices it is irrelevant. But on Omnia there is this space between the touch layer and protective layer and holding at bad angle makes you tap wrong places. So I used common sense and voila... here you have this thread....

Taking into account the number of positive responses I assume that more ppl had similar problem.

jeah and that is the reason wy i don't mock you and i respect this thread, because apparently you helped some guys out. but you must agree it's pretty weird that all those guys are amazed, while it's a logical way (for me) to align your screen. (i'm imagining people hanging upside-down with a baseball-bat in theit hands trying to calibrate their devices B))

again, i'm not mocking you, i'm just amazed... and drunk B) good noight!

The 'logical' way would be to hold it in your hand (like you normally do to operate it) and use the stylus to calibrate.

This way (may i say worked wonders for me) is not that logical at all

Thanks. Screen calibration is very important. I agree. Can you share your calibration data?

In local_macine>Hardware>Devicemap>Touch>calibrationdata

there is five pairs of numbers represeting (X,Y) values of the five spots you pressed during calibration.

Could you share that with us? It is a matter of copying and pasting these numbers to duplicate your accurate calibration. Simple!

Thanks.

[Guest samjuan]

this method is amazing, thanks for sharing bro.

By the way, this is the best method to calibrate any resistive type touchscreen device, especially WM, I used to do it since the M600 and the first Pocket PC WM2003, it works all the time, it has something to do with the pixel size and how sharp the tool you use to calibrate, and you should do it regularly as it goes out of focus often (maybe once a month or whenever you feel needed) I always use a sharp toothpick, and always have a screen protector on, so I don't have to worry about scratching my screen.

This method is proven to improve sensitivity and accuracy of any resistive type device.

Cheers.

[Guest Tatou26]

Thanks for the tip, it works fine.

Now a solution to improve the finger touch sensitivity (at least as a HTC diamond)? Because I've compared and the Omnia is really bad.

Thanks for pointing out to the registry values.

I have created a .reg file that you can edit if, as me, you want to be able to recover the calibrating parameters after hard-resets.

[Guest Motofone]

Ok have been playing around with reg settings...

Now I don't know max settings i may have exceeded them but have been going up and down and found these to make noticeable difference.

My original settings were

Click=1280

Updown=256

[ H K E Y _ L O C A L _ M A C H I N E \ \ H A R D W A R E \ D E V I C E M A P \ T O U C H ]

" C l i c k " = d w o r d : set to 2000

[ H K E Y _ L O C A L _ M A C H I N E \ \ H A R D W A R E \ D E V I C E M A P \ T O U C H ]

" D o w n U p " = d w o r d : set to 750

soft reset required

Touch and scrolling seems improved.....

see what you think / find?...

edit: I re calibrated and none of these settings changed so it appears that maybe calibration just sets the accuracy of the touch to the pixel area.

I have quite big fingers and this calibration method does allow the selection to be a lot more accurate.

Excuse me people but I've to say...

Put this in your heads: That doesn't improve sensitivity, (MAYBE) only calibration!!

That's right:

Hey I'm gonna tell you a secret method to improve sensitivty:

Open your phone and replace the damaged screen for another one. B)

Thanks for your comments - your insight is simply astounding. Your belief that the very frequent comments that the omnias screen sensitivity is only relate to a hardware flaw is disturbing (if this was the case samsung would have released a defective product and virtually every omnia would need to be returned). We already know that there i a software dimension as the later ROMs are much better at detecting screen events than the earlier ROMS.

My understanding is that there are 4 elements which must be integrated to correctly for touch screens to work:

1) calabration (matching the xy coordinate with where you touch)

2) sensitivity (weight before a touch is recognised)

3) periodic changes (the size of change and period before a movement is recognised eg swipe v press)

4) the degree of error assosciated with interpreting the calibration data (finger v stylus)

I am feeling pretty good about the sensitivity of the Omnia screen when I use a stylus. I think Kordi's method helps optimise the results of the calibration process.

@Motofone: I have tried those settings in the past - as on the surface they seemed to align with my expectation of the full suit of elements (ie click=weight, maxcallerror = degre of eror, updown - periodic change) but I cant find any values which give me a noticable change in sensitivity B)

But it seems that Samsung have been tailoring the device the stylus when it was sold to us as a "finger frendly device" - this only seems to be true if you have plastic pointers for fingers (but might make an interesting movie...... Edward Stylus-Hands). Now that samsung has figured out how to get it working properly for stylus navigation - hopfully they will put down their pointers and get it working for our fat fingers.

[Guest ivanxxx]

Hey I've learned something new in this topic.. The protection layer !! Is it the real guilty for bad accuracy of finger sweeping actions?? If it is so can I remove it or is there a way for modification ?? I am dying to have a screen like IPHONE = a finger touch respondent one !!!

Any idea ??
