Sreenprotectors - The hidden Side Effect. - Tilt, TyTN II, MDA Vario III General

This is something i noticed with my device, the screen protector iv had it on ever since i got my mda vario III, today i removed it cose there was dust collecting at the edges of the screen where it couldn't reach as its smaller than the screen then i notice the device was performing alot faster to make sure i wasn't just seeing things i tried playing a game of FPSEce before all were really slow average 10fps when actually playing now i get it around 20fps the game was actually playable not perfectly of course but still alot better. Again this is a possible effect of the lack of drivers if we get screen protector companies on your side who knows i mean who would buy one if it slowed down their ppc which would lower their business.

Lol , the only conclusion i can give you is that your screen protector was actually continuously pushing the touch screen somewhere.
Resulting in the ever lasting htc touchscreen driver bug eating cpu cycles.
You can always check this with an app that shows cpu usage.

Batterystatus used to show it as low

The screenprotector does not weigh enough to be able to create a force large enough to activate the screen.
Here is a different theory: the screen protector does not let heat to diffuse through the screen, outside. Hence, the device become warmer, and the CPU throttle down...

It does if it goes under an edge... my touch stopped working, cause it got slipped under the edge and therefore was exerting force on the screen.

this is impossible because our screens are only single touch, if it was always being pressed then that means the press from out finger or stylus wouldnt work or it wouldnt press most of the time. you would find it very messed up. havnt u ever tried pressing in 2 places on the screen with a paint program or drawing just for fun?

i could see the screen protector "pressing" on the screen if it was stretched or shrunken.
however, have you ever taken a ball point pen and tried to write on a stack of papers? you eneded up with a clear "dent" on the second page, but a barely visible "dent on the third. the screen protectors make the screen less sensitive because it's just another layer. try doubling the sensitivity in your registry from 7000 to 14000 and see if it helps a little. (or the oil from your skin will eventualy collect enough dust, that if you do any heavy literary work on your PPC; you will surely wear out your screen)
I have a couple of light scratches on my screen from drawing; so i prefer the screen is less exact, but protected.
(keep in mind you create friction when you run plastic on plastic; and friction creates heat, brazing the tip of your stilus, ocasionaly making it sharper than it should be.)
I suppose thats how I see it.

Cracking Screens - Thoughts?

First, my Tilt is babied. Then I see what looks to be a small scratch on the screen protector near the vertical slider window. Nope. CRACKED DIGITIZER! LCD appears unscathed.
So what's the cause?
Thermal expansion? (Mine has gone up to 118 degrees F).
Less sensitivity with a "Screen Protector?"
I've lowered the Registry value to 135 for the Touchpad sensitivity which seemed to work well.
Now I'm wondering if it is due to the phone freezing (with Opera) and my attempt to close it down or do anything while it is temporarily frozen. I may press harder on it thinking the first touch wasn't enough.
Anyway, parts on order from Brian at blackberry8100 for $68.
Annoying - and maybe too fragile a screen.

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?

19 decimal?
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.
HastaSSSS
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.

2nd try: Touchscreen accuracy

Hey everyone,
since 2 or 3 months I've got an HTC Kaiser. I really like it, it is equipped with an TF2D integrated ROM, so far everything nice
But as you can see in my device history, I formerly got an HTC P4350, these one was terribly slow! But it had one thing which was a thousand times better than my Kaiser:
The Touch screen was accurate. When I'm working (or whatever) with my kaiser, I sometimes have to tap 5-6 times on the screen until I reach my destination due to the bad touchscreen accuracy.
I tried also a screen allignment but it had no positive effect, it is for alligning the screen and to set the required pressure but thats not what I'm searching for.
I need a screen on which it tap while using Icontact for example and with which I am able to hit the contact which I prefer (and the buttons are really big and not all other ones around... But usually I have to tap several times to reach my destination.
This occurs even a little more whilie using it without a stylus.
And also i think the lowest accuracy is located in the center of the screen. So anyone has an Idea how to solve this matter?
Is a new LCD helpful?
When I used my bosses phone the accuracy was also very low - maybe it is a general problem for the Kaiser? (He has also an HTC Kaiser)
I don't know - so is anyone able to help me with that matter?
Best regards,
Maeffjus
are you using a screen protector?
if so, try removing the screen protector and then check the accuracy.
if the accuracy improves after removing the screen protector, then you can either use the phone without the screen protector or buy a brand new screen protector.
finally, try cleaning under the edges of the frame of the screen with a thin piece of cardboard or a rigid plastic sheet.
No, I'm not using a protector...
I'm often cleaning the screen edges with business-cards (otimal solution *lol*)
The screen was equiped with a protector when I bought the phone but I removed it immediately.
And also the accuracy is bad on my bosses Kaiser...

Water on screen

Has anyone noticed their NC is very sensitive to water on the screen? I find even if the tiniest few drops of misty rain land on it, it's fine for a few seconds and then once I try touching it, the screen totally glitches out and starts detecting spurious touches. If I sleep the screen and turn it back on, that usually fixes it.
In a city like Vancouver this could end up being a deal breaker ;-) I don't expect a water proof tablet but my touch phones like the Milestone and Nexus One have typically withstood little bits of moisture on the screen without impairing usability.
Repeatable test: Open MultiTouch Tester, wet your finger. Swipe it around the perimeter of the screen a few times. Wait a few seconds. Repeat. Wait a few seconds. At some point when you aren't touching the screen, you'll start to see spurious touches appearing on the screen. If you wait even longer for those touches to stop, then the screen will become totally insensitive to all input. Sleep and back on fixes it.
Theyre called screen protectors.. use em.

Can someone confirm if the same behaviour persists with a screen protector?
I don't own a screen protector but I tried putting a piece of plastic wrap over top to test the behaviour. I wet my finger and trace a few circles on the screen through the wrap. I still get the spurious touches even though the water never contacts the screen. The moment I lift up the wrap, the spurious touches stop but the screen is again unresponsive. I have to sleep it off and on before it works again.
Since all screen protectors are some type of plastic or other, I have a feeling this problem would still happen with a protector.
And here is my video showing the "experiment" (no protector/wrap).

Again, same results with plastic in between the water and the screen.

Had the same problems but putting on a screen protector fixed it. No random touches. No need to turn the screen off/on. So much better.
Using this one.
confirmed. it still does it will screen protector. tested with ipad and itouch too see if this was a capacitive screen issue. water had no effect on those too devices. Doesn't really matter because I don't plan using this device outside in the rain.
Well I wouldn't take it out in a torrential storm, but sometimes it's just "spitting" out as it often is in the Pacific northwest, and I'm reading a book or article at the bus stop. And then suddenly it's flipping random pages or launching unwanted apps.

This is probably related to the common phantom touches people get. I know my nook some times register random touches from hovering fingers up to an inch from the screen.
Too much dirt/grease on the screen will also do it. The screen on the NC is (by default) very sensitive.. There are a few methods to "calibrate it", some of which say if you're touching it while calibrating the sensitivity goes down.
I've seen this several times myself, and yeah it's annoying because it goes NUTS. One time I had it remove an app from my launcher, launch another app, then change some settings. I was like wtff gaaahhhhh
No screen protector on mine.. I usually do on devices, just haven't on this one yet.
It's a capacitive screen. A drop of water can make the screen behave strangely because the capacitance of the screen changes where the water is. Multiple drops of water will drive the screen nuts. This isn't new. If you hands are too dry the screen won't register the touch.
It is how they work.......
BN brand matte (anti-glare) screen protector has completely, I mean 100% no lie, fixed this problem for me. In addition, the screen loses it's "tackiness". It's a pleasure using the screen now.

[Q] Can the phone temperature soften the screen adhesive?

Hello everyone.
I recently replaced my broken screen and somehow the phone feels warmer than before, especially when downloading something on LTE and browsing at the same time.(The left side of the screen right about the place of the vent gets warm)
I dont know if this was the case before replacing the screen but now I'm concerned it might soften the adhesive that was used to attach the new screen and with time the screen could come off and break again.
any ideas on this matter?
how much is your cpu temperature when downloading and browsing at the same time?
