every review i've read online before i bought the unit was boasting about how "finger-friendly" the TP2 was, and that you could lightly swipe your finger across it to navigate the menu and that the touchscreen was very sensitive and whatnot
however after 2 weeks of use i find that to be relatively untrue. i've got to apply a fair amount of pressure on the screen to get it to register my input. of course, i'm posting this because i'm afraid that i might be damaging the screen in the process
i have no basis for comparison actually, my only 2 other touchscreen devices at home are an iphone and a cowon s9, both use capacitive screens. i always knew there was a big difference between capacitive screens and resistive screens, i just didn't know it was THIS huge. i can actually slide my finger lightly over the iphone's surface and its registered properly. the sliding probably feels smoother as its glass, but i can live with the TP2's plastic. what do you guys think ? should i get it checked out at the HTC store ?? its on the other side of town, don't wanna waste a trip as if its not a problem
oh yeah and just to get this out of the way, the screen is a membrane and not a hard surface right ?? everytime i press on the screen using my finger or the stylus, i can feel the screen slightly moving down, can also see the surface getting slightly dented at the point my finger pushes it if looking at it from a certain angle.
ps before somebody asks: i only got to test the keyboard at the telco store, some punk had cracked the screen of the display set, so i didn't know about this screen issue until i actually purchased the set
sorry for the long post, but i'd really appreciate any comments
TIA
Well, I don't have an Iphone so i can't tell you about how it compares with the TP2, however, i found the display to be much better than the one on my old XDA. It will probably never as good as a capacitive device like the touchpad on my laptop, but I found it to work very well. You have to apply a certain amount of pressue to the display, because it reacts on pressure, so I guess there is nothing wrong with that. I also see a small dent when I use the stylus and press the display. I cannot confirm the screen slightly going down when pressing it.
To summarize it, i use the Stylus 90% of the time. It glides much better on the display than my finger does so the overall experience is slightly better when using a stylus. Plus i don't get any greasy fingerprints on my display.
However the 10% I use my fingers to work on it (and 25% of that 10% is spent on polishing I found it to work pretty well, so in general I don't think that the reviews were off when it comes to finger usability.
What you are describing is probably normal. Resistive screens do require pressure. The TP2 tends to require less pressure than others, but nonetheless it does require it. There's no comparison if you compare it to a capacitive screen device because those don't require pressure at all.
The flexing of the screen that you described is something all resistive screens have. Again, if you compare the screen flex of the TP2 to earlier HTC devices, it's greatly improved.
To be on the safe side, go to a store and try out other resistive screen devices and see if you experience the same thing as your own. Then you'll know what is considered "normal".
thanks for the replies, i'll probably head down to my telco's store and see if they've replaced the display set then.
any other comments ??
You know I thought the same, waiting for a cab to increase the sensitivity because at the moment its quite annoying pressing buttons more than once...
From a few years to nowadays i´ve always used QTEK/HTC devices, my latest one is, ofcourse, HTC RHODIUM, the rom it has installed is RUU_Rhodium_HTC_PTG_1.19.410.0_Radio_Rhodium_3.44.25.27_Signed_Ship, and the screen is very sensitive and responsive, i´m just very pleased with it overall, it´s the best.
Cheers.

you don't need .cab
just change in registry...
HKLM/drivers/Touch Driver/pressurethreshold, (default=10000)
(I might not remember perfectly, but it's something like that)
try this?

this might help just re align your screen again using little pressure then your screen will not need some much pressure to work.
I have found the this not only aligns the screen but the pressure as well.
mine I just have to lightly touch it and dont have to press very much at all.
Cheers
Just out of curiousity, do any of your screens have a kind of bounce or mushy feel to them when you press on them? I look at mine from the side and there is clearly a movement up and down when I push on it. I also have the screen protector on it too, but that should be firmly emplaced. It looks like from looking at it side on at the center of the screen is sort of unattached whenever I depress on it. Is this normal?
Same here
My mesage should not be to short to post now BOARD
It's perfectly normal that your touchscreen dips a little when pressed on; In fact, that's how resistive touchscreens work. From Wikipedia:
Resistive touchscreens are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When contact is made to the surface of the touchscreen, the two sheets are pressed together, registering the precise location of the touch. Because the touchscreen senses input from contact with nearly any object (finger, stylus/pen, palm) resistive touchscreens are a type of "passive" technology.

It seems to happen on all phones where the screen is on a slider. I've seen it on the Fuze and Kaiser, too.

i think the OP is about the screen itself, not the top half of the phones. the screen thing is inherent and i've got no issue with that, but a shifty sliding mechanism is annoying, though not present on my tp2

Yeah, however, I would have thought the screen would have been a little tighter in terms of it's air gap between the resistive layer and the LCD itself. I used to have an 8525 and there was never the kind of airgap between the touch screen and the LCD at all. With this there is a noticable gap in the touch screen layer to the LCD. Especially in the middle. I just would have thought it would have been a flatter tighter stretched across the screen.
Hey Guys,
I know that most of the questions I read were about the S Pen being too sensitive. But in my case, I feel the S Pen is not as sensitive as it should be!
When I put the pen in the slightest contact with the screen and try to scribble, nothing comes up. I feel I have to push the pen a bit more strongly to get some writing on the screen - and that takes away from the sensitivity of the S pen which Samsung brags about.
Is anybody else facing this problem, where you feel the S pen has to be pushed too hard for it to start writing on the screen? In my opinion, as soon as the pen comes in contact with the screen (even the slightest contact), it should start writing.
Thanks guys.

I am having this issue a little now. At first the s-pen was fine and performed as expected but now it seems like it needs more pressure to register scren taps etc although the pointer shows as normal whent he pen is close to the screen
This is normal in S note and some other apps where pressure sensitivity is needed. Samsung has designed it in that way.
Same here, first day the pressure needed was very low, now I need a lot of more and the traces of the pen have like 2 options, little press (more than before) and a lot of pressure for thick lines, nothing in the middle.
And I can corroborate this because with my other wacom pens of tablet pcs doesn't have the problem of the samsung now.

read this thread http://forum.xda-developers.com/showthread.php?t=1925212 Apparently there are two adjustable potentiometers beneath the S pen switch which can be adjusted for increasing or decreasing sensitivity of the pen . most people including me are suffering from greater sensitivity . I adjusted the potentiometer to get rid of this problem.

The thing is that my pen can write with slight pressure but a little more than before, but the real problem seems that the middle one levels are lost and were working the first day.
I have a rooted 2013 N7 running 5.0.2 that I recently installed in the dash of my car. During normal (handheld) use my touch screen works OK though it does have some periodic difficulties as seems to be common with this unit. However, when I mount the tablet in my dash, the touch screen is almost completely unresponsive. The tablet is mounted behind my stereo trim bezel so that there is plastic trim piece in contact with the full perimeter of the front glass. I believe the trim piece does not overlap with the LCD screen. Even so, I am assuming this is screwing with the touch responsiveness. When there is a little pressure on the edges of the screen - most of touch is unresponsive. Has anyone run into this problem? Ideas, insight, links to other threads are very appreciated. Thank you.

In your case, there are 2 reasons I know of that interfere with the touch operation: (1) the grounding issue where without holding the tab in your hand would cause unresponsiveness. Easy to test: if you leave the tab on a flat surface without touching it, and it doesn't respond well to touches, you can try multi-fix hacks. It helped in my experience. The battery percentage also affects - the lower it goes, the less responsive it becomes.
If it does respond then (2) the problem is what you've already identified. Any pressure, however slight, on the tab or glass would distort responsiveness on some units. In my experience, something as innocuous as adjusting the angle at which the tab stands on a case makes a difference. Here, I've found no cures but to maintain it at an optimizing angle.
Thank you for the reply. I am not having the grounding issue so it must be pressure on the edges of the screen. I'm still searching for a fix to this without having to redesign my entire mount.

So i bought the a50 cause i wanted a bigger phone like the note at a cheap price. Loving the phone, so i decided to spring for an active stylus, the stylus actually works very well on my g6 and dell touchscreen but for some reason the upper half of my a50 isnt very responsive, and where it does respond is only on the edges. If i start a stroke from the bottom of the scren it will follow through to the top, most of the time. But if i start at the top and move down, it only appear towards the bottom off the screen. Tapping is even worse, almost no response on upper half.
I have no magnetic cases, ive tried two a50s, with and without screen protectors. Always the same result. Heres some pictures to help visualize, does anyone have a fix for this?
Scribles represent dragging, dots represent taps.
You could try increasing the touch sensitivity.

Thank you for your response. I should have mentioned, the problem is identicle, with or without touch sensitivity increased. The stylus work on a note 9 perfect as well. Starting to suspect its a software problem with the a50.
