water wave produced when press on the screen

HI all, I dont know if anyone has this situation...
Everytime I press on the screen, the screen generates a bit like a water wave and the situation is just like pressing on a LCD monitor.
My old M3100 doesnt have this situation...how about u guyz? do you have water wave when u press on your tytn ii?
thanks

Hmmm, maybe it's because you ARE pressing on a LCD screen... I never press hard enough to see it, but I'm sure it would.

Yea seriously, how hard are you pressing? I don't think you need to be pressing nearly as hard as you are. I can see the ripple if I press really hard, but that much force isn't necessary for your taps to be recognized (and its probably not good for the screen).

I was going to post about this earlier. I too have this problem. I owned an 8525 before, and it never rippled unless you were exerting massive force.
My current Tilt you barley tap it (like say, you are touching the dial pad to call someone) and it has two large ripples happening.
Is this normal for everyone? I called ATT about this, and they just sent me a new one. I just haven't opened the new one yet.

I found this out cos I am using my finger to use the Touchflo...I didnt apply a very aggressive pressure on it...I even see the ripple when I slide the keyboard out. Is it normal?

no its not normal if you are pressing softly and having wave like that. Please do the warranty exchange.

AT&T just sends you a new phone without even asking for the old one back?

I've seen the small ripple when sliding the screen out. Maybe it's the magnetic switch..who knows. Doesn't happen all the time.

I have uploaded a video on youtube about my screen problem
I only pressed it gently on the screen.

Do you guyz have this problem?

Anyone? it seems I am the only one to have this problem...

Hi
It depends on the LCD panel, there are different types of panel, some will ripple when pressed or distorted even very slightly others don't.
The problem with asking others is there are at least two different types of LCD panel used in the Kaiser. One we know to be transreflective that works in direct sunlight and looks kind of green rather than black when off, and one that's not transreflective that is black when off and doesn't work too well in direct sunlight. These panels may well be using different LCD technologies in other ways meaning not everyone will see the same as you.
Mine isn't transreflective and doesn't do this, so perhaps you have a transreflective type that also ripples under pressure. It isn't a fault with the LCD display, rather HTC sourcing whatever types of panel they can get at the time for the cheapest price. You wouldn't normally use a panel that ripples when pressed on a touch screen for obvious reasons, but HTC have. Maybe it was a shortage in supply and there are not many that use this type?

It shouldn't happen. Exchange it.

They charge you for the second one and then refund it when they receive the old one.

They sent my second one out to me at no charge. They forgot to include the shipping labels...again... so they will probably just end up letting me keep the device.
Anyhow, my Tilt ripples exactly in the same place that the video showed, and in the same way.

Is the ripple gone for your second one?

Where is your Tilt made?
What's the model code under the battery (ie. KAIS300)?

We don't know this at all, there apparently are at least two screen types but neither was transreflective, both blew out in direct sun.
The ripple is a function of the thickness of the glass screen. Since liquid crystal displays work by electrostatic twisting of a liquid suspension of quartz crystals thereby bending the light to allow it to pass thru polarizing filters, any physical movement of this suspension will also cause visible light artifacts. So if the front panel is lighter weight material, it will show more "ripples" if pressed firmly.

There are different technologies used in the production of LCD panels and how the glass is spaced to give room to create the pockets for the liquid crystal.
Some displays "water" when you press them, others don't, it depends on what the type of LCD display it is. My monitor at work can be pressed and nothing happens, my one at home is the opposite. It's not hard to find this explained on the internet.
The Kaiser is using different types of display using different technologies. Typically for touch screen applications (unless the display as a touch glass front) would not be of the type to ripple when pressed for the reason it will be pressed and flexed, but obviously HTC is supplying anything they can get.

Screen sensativity.

So my only complaint so far is the screen sensativity.
I know this doesnt use a capacitive screen, so it needs physical pressure, but it seems to me the glass on the top of the screen makes it need alot more pressure than i'm used to. The middle of the screen seems to be more sensative, and the outside less sensative.
You can test this by putting your finger down on HOME in touchflo, then scrolling to programs and back again. If you pres hard, it will go back and forth. If you use less pressure at home and programs it will load the programs or home screen, as if you released your finger.
So i know there's two reg keys for this:
HKEY_LOCAL_MACHINE\Drivers\TouchPanel
By doing a screen slignment and pressing hard with the stylus i get a lower value here, and by pressing lightly i get a higher value here.
So high value = detects lighter press, low value - needs harder press
HKLM\Software\OEM\TFLOSettings\fingurepressure
This i'm confused about. I tried setting it to 0, 2, 14, 200, 255, 600, and there's not noticable difference as far as i can see.
Is there some sort of program that can read the the pressure from the screen and display it? This would help make the tests alot more scientific!

Someone posted this tip in the tips and tweaks thread above...maybe useful to you??
One tip for changing the sensitivity if you don't want to mess around in the registry:
- run the Align Screen setting (under Settings/System/ Screen)
- when you press on the 'targets' with the stylus, use VERY light pressure...just enough that the tap is accepted
- I usually tap a few times on each target, starting too lightly, and then gradually increasing the pressure until the tap is taken
- do this for each of the 5 targets
I found this seems to make the Diamond calibrate a higher sensitivity for its touch-screen, so finger touches can be much lighter.
This is probably a safer way to change the sensitivity, as you don't risk putting an invalid number into the registry.

Thanks, i already tried that.
Can someone tell me their value for this key?

I've just about had enough of this touchflo.. pretty but soooo anoying to use
Today on about 3 ocasions i was navigating through it and got a call.. the lights on the touch wheel were flashing and it was playing the ringtone, but the whole phone was frozen for about 4 seconds. Eventually the call popped up and i was able to answer!
I think i'm going to diable it and do my best to make the rest pretty.

You just have to be patient...the roms are not mature yet...
In 3 months you'll see that Diamond will be the best phone out there
I also am trying to find out the best way to configure the finger sensitivity.

yeah but 3 months is a long time... i have to do something to stop myself smashing the phone on the floor on frustration!
for now i'm going to disable touch flow, and i'll come back to it when a new rom comes out.

Have you tried the new rom 1.37.XXX ?
Bye

I have a UK diamond.. so it came with 1.37.405.1

I've just done the "light tap" trick, and now it's perfect...
Could it be that you have a defective device?
Bye

Its better with that 'trick' but still anoying. I have a feeling i'm just too used to a capacitive screen.
The wierd thing is with the light tap the key HKEY_LOCAL_MACHINE\Drivers\TouchPanel ends up back to 30 to 50 decimal.

i only bought it today yet im seriously thinking of taking it back. The iPhone is just the better product, and always will be, unless Microsoft and the software developers get as passionate as those at apple.
Its Laggy
Its un-intuative
The touch screen isnt as sensitive as it should be. (why are they still using resistive touchscreens)
And the opera browser isnt all that either, it doesnt redraw quick enough for the full page display thing to really be all that impressive on zoom in/out and leaves chessboard squared at it struggles and chuggs to redraw.. . .not great, not when the comptetition is as good as it is. . . . .im thinking 3G Iphone, ****ty camera or not.
Loose the 6.1 and stop trying to polish that turd with TouchFlo's. Yeah good effort, but it just aint good enough
J

WM is just a huge resource hog. The touchflo is slow because its a plugin for the today screen, which then calls on windows API's to draw onto the screen.
Its such a long long way round to get to the hardware that its just slow no matter how well u code.
I just hope someone ports android to the diamond, because the hardware is amazing, the OS is a pile of ****!
BTW they use resistive touchscreens to have increased touch resolution. Also a stylus wouldnt work with a capacitive screen.

I prefer to work with resistive LCD than capacitive...
The capacitive have better sensibility, but are less precise...
Although the Diamond LCD is not as sensitive as a capacitive, it's sensitive enough to work well with the fingers...
It's just a matter of tweaking.

Resistive screens use a grid of conductive material, sandwitched between the glass and a conductive layer. They alternatly pass an electrical current on each line of the grid along the x and y axis. When you press the screen you touch this grid onto the conductive layer and the current passes through it, which is detected. You can make resistive screen that have a very high resolution of detection, and the resolution is always what you design it to be.
Resistive screens are pressure sensative, and by design can't handle multi-touch.
Capacitive screens use glass coated with a conductive coating. The edges of the screen are connected to conducters. Each conducter has a different frequency oscilator connected.
The capacitance of a human finger changes the impedance of the screen, and so changes the frequency of the oscillator circuit. This gets converted to distance from each oscillator and so a co-ordinate.
The resolution is limited by how acuratly you can detect changes.
Typically in electronics very small changes are hard to measure because they are indistiguishable from noise.
Capacitive screens can handle multi-touch, but the resolution of each touch is decreased in that case.
Capacitive screen resolution is not absolute and can change with increased noise in the system, or by multiple capapcitive effects on the screen - like multiple touches.

Missed Call/New Text Indicator Light

Hello everyone, I'm new to these forums as well as a new Xperia X1 owner.
I love pretty much everything about this phone except I find one issue that doesn't seem up to par to my previous phones and I can't seem to find a way to adjust it.
Basically, if there is a missed call or a new text that I don't see right away, and my phone goes black (stand by), the 4 lights that light up around the phone seem to have really long intervals and barely flash. I feel like I have to stare at the phone for a good 5 seconds before I see a flash and it's not even that bright.
Is there an adjustment that I'm not seeing, or a way to adjust the intervals and brightness? I can't be the only one with this problem, my old phones had very bright and quickly blinking lights.
Thank you.

advanced config offers some options on that (at least patterns, not sure on brightness), illumineria in themes&apss even more
have a look, best

Screen brightness uneven -- anyone else?

Folks,
Got a question for you -- as per the title. To give you a little background, I bought an S2 8.0, loved it, and then decided that I really ought to replace my existing "data plan" tablet from the S 8.4 to the S2 9.7. So, good-bye to the S2 8.0, and I've got a new S2 9.7 LTE.
All is well, EXCEPT for some screen oddness. I'll have to post some pictures, but I think I can describe it well enough. To begin with, I don't really like "busy" wallpaper -- I just use a solid-color, medium-to-dark blue wallpaper as my background. What I really notice, both in portrait and landscape orientation, is a darker band at the top of the screen -- again, it happens in both portrait and landscape orientation. It seems to be a "viewing angle" thing, as the dark "top" in landscape orientation doesn't turn into a dark "side" in portrait orientation. Instead, when I move to portrait orientation, then the top of the screen has this dark band, and the sides are just fine.
But I don't notice quite the same thing happening when I get into some apps -- for instance, the yellow/orange top band in the "Memo" application doesn't turn noticeably darker. But the green top band in the "Evernote" application shows it IN SPADES, though it's a really thin band at the very edge of the screen. And, again, it's always at the top, no matter which orientation I'm in, that I see the dark band.
Anyway, that's the most obvious stuff. However, when you back up and take the whole screen in view, what I'm really seeing is A LOT OF COLOR CHANGE as I angle the tablet towards me (more vertical) and away from me (more horizontal). Again, just go into the Memo application, and lay your tablet flat on a table, then grab it and tilt it up towards you -- do you get a big change in color, or does it stay the same? I guess I would say that the "white" color "turns bluish" as I raise the tablet towards me (making it more vertical), and it goes more to a normal white when I lay it flat.
I can understand changes in screen quality due to viewing angles, but that's not something that I associate with OLED screens. I sure didn't see anything like this at all with the S2 8.0 that I had. And I've started looking at S2 9.7 tablets in stores, and I really haven't seen anything like it in the stores. Thus, I'm definitely thinking about returning the thing -- unless it's really a case of "they all do it."
So, if you guys could check out your tablets and let me know if you see anything like this, I would appreciate it. It's not worth taking the thing back and asking for an exchange if what I'm seeing is common, but I'm definitely a bit disappointed in the screen quality that I've got with this tablet.
Thanks in advance for checking this out for me, and for any thoughts you'd like to send my way!

I have yet to see an S2 that can display a uniform white screen. I can always see a light pink/purple tint on a white background. If all you're doing is consuming media you will never notice, but if you're reading anything with a white background it gets too distracting. I don't see any issues with uniform brightness though, it looks perfect from that standpoint.

Understood -- thanks. I installed a couple of screen testing apps, and they show no issues. For instance, I pulled up a full-screen blue that was very similar to the blue I'm using for my background, and it was nicely solid blue. Then I pulled up a full-screen green that was similar to the top of Evernote, and it was nicely solid blue. Then I pulled up a full-screen white, and you could see what you and I have both mentioned -- it does change colors a bit as you move the screen around.
So, it's just very strange what my S2 is doing -- it's like it must have something to do with other on-screen elements. I'll definitely take it back and exchange it for another one, but I'm just trying to get a grip on whether this is happening on any other S2 tablets. And it definitely appears that it isn't.
Thanks for your reply!

I've been checking my T815 a little while ago after noticing similar behaviour. The way I see it, the tab S2 screen is very sensitive to the viewing angle. Not so much in blue and red, but very much so in green. In fact, to get a proper green, I have to look dead on. I even notice a change in the green colour: dead on it's yellowish green, while even at a slight angle it is an uglier green. The first is clearly what the device is calibrated for, because that's when things like skin tones look perfect.
I used the *#0*# menu to test.
I compared this to my other devices. On the note4 I didn't notice this. But that may be because of the smaller screen. On my previous tab, tab77, the effect was also completely absent. But that one has a completely different oled layout.
I've already eliminated display modes and auto brightness as influences. I still have to look into the effects of ambient light, since the displays of my devices do reflect differently when turned off. In fact, under some angles the tab S2 reflects a bright white lamp as pure green. While the tab77 always reflects the same lamp as white.
I know that the tab S2 has an rgb matrix that has two Gs for every R and B. That's probably related to the effect I'm seeing.

Non-uniform intensity across screen at low-brightness settings?

Hi,
Has anyone notciced un-even brightness across the screen at low light levels (for darker colors)? I thought it was just the nature of these OLED screens, but I don't see this with Galaxy Phone with similar display type, so I'm wondering if I just have a defective unit with bad display.
To test it:
- Do this at night (when ambient light is fairly low).
- Lower brightness down to the lowest setting (turn off auto-brightness)
- Open Chrome browser, and close all tabs, so that you get a blank dark screen with just the "+" icon. This leaves a dark gray background, just enough to notice if there is any uneveness in brightness.
On my unit, I see about 3-4 inches of bands/streaks of darker areas at bottom half of the screen. If I rotate the tablet, the darker areas stay in their physical location (so these bands become vertical instead of horizontal), so I know it's not a software issue.
I have a couple of weeks left before I need to decide on whether to exchange the tab, so would appreciate if anyone can help me verify if this is normal thing with these screens.
Many thanks, Tony.

I have notice a similar thing, mostly on gray - dark gray backgrounds, and not necessarily at lowest brightness (low enough though). I wanted to check about it on a couple of devices on display at retail stores but it's hard to test there.

Hi tonyc1,
Having had 4 of these I can confirm that this unevenness is normal on the 9.7" screen but was not present on the 8" model.
I went through 4 to get one that was reasonably even, 2 of them were pretty awful to the point that the greyscale was all over the place.
The unit I settled on has a slightly darker band in the middle of the screen and a slight darkening at the very top.
I owned the original tab s 10.5 and have to say the screen on that was more even and detailed, I prefer the former factor and speed of this S2 but the screen is a step backwards.
Hope this info helps.
Cheers

Thanks for the notes and confirming this is a somewhat common issue. I guess I will live with it for now..
