I heard from a friend that someone is building a phone where the touchscreen keypad is almost as easy to feel as a physical hard-button keypad.
The virtual buttons (0-9, *, #) are spread out in a typical rectangular grid over the whole screen, with large gaps between them. When you (lightly) move your finger across the screen, it vibrates as your finger is passing over any button. If you want to actually press the button, you have to push your finger against the screen harder (this event is acknowledged with a beep).
This sounds like a great interface. Has anyone seen/heard of it? It also seems relatively easy to implement on any PocketPC, unless there are some problems that I'm not aware of.
I'm using one application that uses vibration as a feedback -- Phone_Pad_Vibrate.cab. However, it vibrates only when you actually press a button. I think it's a great app, but obviously its purpose is very different from what I'm talking about (e.g., it won't help you find the right button if you just shift your finger around the screen). Also, I found that it's not reliable -- if I use fast, light touches, I can dial a whole number without any vibration. It may be due to the lag between the button press and the vibration, or due to the different pressure threshold used by this program and the actual phone dialer. If it's the lag, I wonder if it's a technical limitation of the Kaiser.
The screen on the Kaiser (and most other PocketPCs) isn't pressure sensitive, that is, it can tell when you are pressing, but not how hard. You would need a special screen to achieve that.
You are talking about screen technology more advanced than most PocketPCs are currently equipped with. the iPhone has what is generally regarded as the most advanced touch screen in a mass produced product. The software would need to implement it, but the screen's hardware would need to be able to do it in the first place.
I recently purchased a Vogue off of ebay and tried out the SD Card version of Android running Incubus26Jc's Super FroYo 2.2. I wanted to do this before installing to NAND to try it out. After trying it out for a bit I noticed that the touchscreen is not that sensitive.
For example, if I try to swipe with my finger from left to right to get to the second home screen it requires me to swipe from the very edge of the device (if I don't do a swipe across the whole screen it doesn't work well) and push down hard (as compared to another newer device like the iPod Touch). Tapping the screen works fine. Other things I noticed about the screen is it isn't easy to view it at an angle and pressing down with my finger sometimes changes the color of the area immediately around the finger.
My question is whether the device is faulty (in which case I will try to return it to the seller) or is that just the nature of this older touch screen. Or maybe it has to do with the fact that it is installed to SD so it is slower to respond?
no there is nothing wrong with your phone.. the vogue uses a resistive touch screen witch requires a little more pressure than say the itouch or any new touch screen device... they have a capacitive touch screen witch uses electric currents i think.. i prefer a capacitive. but try the screen calibration app and press lightly that might fix your problem
and you shouldn't press very hard they could really mess up your screen
Try using your fingernail instead of pressing harder.

Is there a setting in Andorid to make the touch pressure more sensitive. I recall do registry edits in WinMo that accomplished this. The screen in Android just seem to require more pressure then what I remember having WinMo set to.
It also could be that I'm just use to capacitive screens.
Thanks

ADB/Terminal:
echo "3072" > /sys/module/tsc2003/parameters/sensitivity
I've tried it and I could mess it up enough for it to noticeably lower sensitivity but I could never tell if it actually increased it (but it probably did).
Edit: One thing I noticed is that I could never get the settings to stick beyond a reboot.
lightly touching during screen calibration seems to work.
I was having a similar issue with "touching like you mean it" to get things to work. I tried re-running the calibration tool and pressing with the stylus as light as i could and still get a reading. its not like my incredible, but it is silky smooth.
I am not sure whether it is my mind playing trick with me or not, but I feel like my phone is less sensitive after I did the hard reset (power+volume down). Sometimes I need to press 2-3 times because the first light tap was not detected.
So is there anyway to increase the sensitivity?
I have the same problem, but no idea that is the hardware or only software problem.....
Fresh owner of this Optimus 2X in France, in our community, frandroid.com, we encounter the same problem , I think this is a software issue.
Did someone already contact LG??
Maybe they should include this into the bug list thread.
May I know were you guys having this problem since it is out of the box? or after reset?
I have the same problem started from day 1 till now
I have the same issue and already thought I'd be the only one having this problem.
I would not say it's a problem with sensitivity, but it feels like the touchscreen goes into some kind of sleepmode where then you need to press a second time, to wake it up.
Continuous touching is no problem. (like when typing rapidly on the keyboard)
This video is not from me, but it shows the problem.
Have a look at 13:28 and 13:37. The reviewer tries to hit the "Ackermann" entry, but the touchscreen does not recognize the touch. At 13:37 the guy has to press another time to get the entry selected.

Yes! The touchscreen is definitely less sensitive than my old HTC Hero, and gets quite frustrating sometimes when a scroll misses the first part of the movement or a click is missed.

just in case, are you guys using 20110218 baseband too?
The same problem here. If I unlock the screen and then tap on any on screen apps, I need to touch again for it to open. Only the first time though, after that it function ok. I think this is a bug and needs to be fixed... I have my pc for double-click.
Yep, count me in. Same problem here. Sometimes screen taps aren't registered. Will do some research later on, but I think it's a software problem. (maybe you have to tap 2x as fast )
Hi,
same problem here!
Potentially a driver issue. A Nexus S user had a similar issue in this thread: http://forum.cyanogenmod.com/topic/18431-tuning-driver-to-deal-with-unresponsive-touchscreen/
He managed to tweak the driver and it works fine now. Need to know C++ (I think?) to understand though.

I see, then probably they will fix it on the next update/gingerbread?
Same issue here.
Correct me if I'm wrong, but the problem seems to be that the screen has zero tolerance when it comes to tapping and swiping together. If you tap and slide your finger a bit directly after the tap, the tap is ignored. In other words your tap has to be a steady tap when you click on a button or an app. Right on the spot and with no swiping or sliding afterwards. I can't reproduce this on any of my other devices.
Ergo, it seems that the natural tapping I'm used to isn't working on the x2. It seems like I have to adjust my tap. I think that this could in principle be solved with a setting somewhere, because clearly the x2 is capable of registering this in for example a web page.
The great thing of this is that you can safely tap and swipe in the app drawer to scroll up and down or left and right. The downside is that a tap with a little swipe isn't registered at all. I would say that LG has choosen here for a wrong setting.
My personal experience about screen sensivity.. can you confirm if it's the same for your device?
I noticed a strange touch response.. and after some tests, I can say that the touch screen and icons are influenced by the surface where the phone was put!
with the phone in my hands, it's all ok (only sometimes - rare - I need to tap more than once).
If I put the phone over a glass surface (like a glass table) without touching it with both hands, the touch and the icons not respond!! NEVER!
If I put the phone on my scanner the touch screen works ok, but the icons not (or only few and rare taps was detected).!
If I put the phone over my big Onkyo amplifier.. It works like in my hands.. or better!! even without touching with hands.. only with a finger!
Put it back on my glass table.. and all stop working again. If I put a aluminium foil under the phone (between phone and table).. the touch and the icons works again !!
If I put it on the bed.. it don't work.
LG support say that they have tested the phone about this issue after my report.. but no strange response was detected by them. I don't know if they really tested it..
Try it and let me know what you think about!
tested on glass surface, I can press and swipe through pages with a finger without problem.
it is true that my device is not so responsive, but aint reaching that level yet
i read about a similar behaviour on other devices because some devices need a proper grounding for the capacitive screen to work correctly. You can find this problem via google.
Some devices have problem in a car-mounting, for example.
But i think thats not the problem the thread-opener talked about?
Guys I'm looking to get this phone and after reading Engadgets review of the X2 where they mention that the screen is not as sensitive to the touch as other phones I got a bit worried and started googling which lead me here!
Is this true? The screen isn't very sensitive and you have to apply more pressure than other capacitive phones?
I know that the OP is talking about a different issue but I reckon LG will get that sorted out via software update, or at least hope so!
Please do post your experience about the screen sensitivity of the X2 as this is putting me off. I currently have the Motorola Milestone 2 which is very sensitive to the touch even with a screen protector on it.
Cheers
I'm having a weird issue with a phone that I'm otherwise completely happy.
The screen feels too sensitive to the touch, which in turn makes pretty difficult to type quickly or results in many accidental presses.
Running the latest Lineage OS 20.0.
To reproduce:
Open keyboard, and hover your thumb over a key. SLOWLY move it closer to the screen where it's touching lightly. You should get ridiculous key spam, like a full row in 1 second.
Possible issue:
It appears that the 'finger' area required for a touch to be registered is too small
What I've tried:
Disabling haptics, different keyboard, changing "Cursor speed", a Magisk module that was supposed to add touchscreen sensitivity control.
Any pointers are very welcome, thank you!

I can recreate this as well. I don't really see how it could be a problem. I don't get accidental touches, in fact I find that the screen isn't sensitive enough and sometimes it doesn't register touches. The phone had a touch problem in Android 11 where it wouldn't register touches and I guess the devs tried everything they could to fix a display that was just too garbage to be saved anyway, so now we're stuck with how it is. I guess you could try a GSI with open source drivers that you could edit yourself since the drivers we have are closed source and the custom ROM devs (which should know better than anyone else) told me they couldn't fix it since they didn't have access to the drivers.
