Touch screen issues, A70 movement detection has low resolution. - Gen8, Gen9, Gen10 Q&A, Help & Troubleshooting

Ok, some people were confused as to what my problem was with my other post, They thought it was a performance lag issue; possibly due to low memory. So I am reposting, I am also making it a poll, as some mentioned that a downgrade fixed this behavior on there units.
I have noticed my touch screen does not have smooth response in apps. To confirm I downloaded a app that tests mulitouch; I used "multitouch vis test".
When moving my finger quickly, or swiping, the finger tracking of the touchscreen seems fine. The problem arises when moving slowly or making small movements of less than 10 pixels; that is when you can see that the touchscreen does not track smoothly. You can see the output on the screen stay in one position as you slowly move your finger, then suddenly jump several pixels. It repeats this process as you continue to move slowly, often times the output on the screen is still lagging behind your finger. (it is not centered under your finger even after the jump) This happens even on a fresh boot, and I have tried the touchscreen calibration several times.
Overall it seems like the touch detection is low resolution, and can not detect fine/small movements. If the ones claiming it is dependent on firmware version are correct, then this could be fixed by Archos. If I get enough responses to the poll, I will contact Archos if the results point in that direction. If this is a fairly rare issue, then I know my A70 is defective.
Edit: From the responses here, it seems that the display can detect point touch to a very fine degree. The problem is that the movement detection algorithm is low resolution; the device has to detect movement of several pixels before outputting that movement. That means it can be fixed within software. (unless it is built into the touch screen controller chip)

I run calbrate touch screen and it`s now Ok.
Did you try this?

Yes, several times.

Those claiming not to have this issue are ahead, but the sample size is too low.

Can you edit the polls for A101's and A70's separate?

Polls can not be edited, but this is for A70 only. You having issues with the 101?

Hi all,
I don't know if this is of any relevance to the problems you guys are experiencing, but I thought the screen of my 101 was broken.
The problem was, me coming from a different china tablet with resistive screen, that I was applying far too much pressure to the screen and capacitive screens don't respond well to that.
These screens need almost feather light touch and are very, very responsive and the tracking (at least on my 101) is excellent.
I hope this helps...

I'm not sure you can accurately conclude that the touch response is low resolution for slow finger motion with the test scenario you are using. I say this not based on some intimate knowledge of Android touchscreen drivers, but on years of experience programming human interfaces at a low level for embedded systems. From using my Archos 101 and a Zenithink ZT-180 (Android 2.1 tablet), the touch response feels similar to how some mice (mouses?) interfaces might be programmed, but tweaked to compensate for the vagaries of using a fat index finger that lays over many pixels at once pretending to be a pressure sensitive mouse cursor. I can imagine the touch interface having to pay attention to how many pixels are being touched by your finger and how many of those pixels at the edges are noisily changing from inactive to active touch-wise. It's actually very impressive how intuitive it feels to use a good touch interface when I know how much logic is required to say this is a touch and hold verses a hard quick tap verses a small swipe verses whatever. As in mouse programming, there are logic thresholds based on how fast the cursor is moving and how quickly it's accelerating. It could very well be that your A70 may not have all the speed and acceleration thresholds set optimally, or to your tastes. I am only suggesting you keep an open mind and dig deeper to learn how these things work.
Bye.

I'm not saying the hardware is low quality, and it could be software setup. I know a good deal about how these things work, or at least have the ability to understand the technical side. I am an avionics Tech by trade.
When testing the slow pixel to pixel fine movement adjustment, I do not slide my finger, I roll my finger on the screen. This allows smoother and more precise small movements. It is a technique I have used on other devices that works very well.
The issue, is that my phone and 10in tablet (non Archos) does not behave this way. It is a usability issue. When playing a game like Angry Birds, how precise you can aim is the difference between beating the level and failure.

I have noticed this issue too, with "multitouch vis test" When i move my fingers over the screen slowly it jumps at least 4 Pixels.
But the screen has not a low resolution, when i lift my finger up and place it down again, i can "select" for example 412 then 411.
I have the archos 70 it

Edit:
When i use this program on my Desire HD, ich can slide from Pixel to Pixel by rolling my finger.

Definitely the software movement detection algorithms then.

If we get some more votes on here, I am going to point Archos in this direction.

hardware or software problem...???
I have already contacted Archos support about this. They just told me they've never heard of this problem... I responded back with more detailed info and they have just ignored me.
I have also posted info on this on archosfans.com forum. There doesn't appear to be many people who care, or have this problem. I am trying to find out if there is defective hardware which means I need to get it replaced BEFORE I void the warranty with the developer firmware, or if it is expected because of software optimization that will be fixed.

that poll is completely unscientific

don't care about the poll
I don't really care about the poll. I have this issue and trying to figure out if anyone else has it or if I have a defective device that should be replaced. This was the only thread I could that related to my problem, and the original post explained it perfectly.
Should I start a new thread about this problem rather than a reply to this poll?

Coordinates seems to increment/decrement approx +- 5 only. Slow movements are delayed somehow. Not really a big problem, but if it is a software issue I would really like to see some improvements in the future.

It isn't scientific, but if a lot of people had participated, it would have been a good guide.
It is rather annoying, but no point in replacing it if it is a common issue with every tablet.

Marine6680,
Exactly my point. I don't want to waste my time in trying to replace something that might not be broken (in a matter of speaking).

Can it be more finger friendly ?

Hi
There's allot of improvements, shells, skins..... that are finger-friendly...
I Really like it finger-friendly, it is more comfortable and usually looks good.
I've noticed that the TOUCH PAD of the IPhone is very sensitive for finger touch, while the Hermes needs a very hard touch (Relatively).
Is there a (hard) sensitive touchpad (Digitizer) for heremes ? (something more finger-touch friendly...)
I was looking in ebay, and noticed that there are 2 kinds of Digitizers, does someone knows the difference ?
Digitizer G1
Digitizer G2
Tnx.
I'm afraid neither of those will do what you might think they'd do. The term digitizer refers to a module that consists of a matrix to sense particular change of state in one (or more) given point(s) and translate that as coordinates data in digital form.
There are maybe 2 revisions of them in the ebay links you attached but I don't think they work differently, perhaps one has better sensitivity or responsiveness.
Digitizers activated by pressure works differently than ones activated by mere touch (capacitance). The first is noticable by the requirement of stylus or something to "press" a point to "short circuit" a tiny area in 2 thin layers that are stacked together, they know where the "short circuit" is and report that as the touch point. The latter is activated by the fact that the touch actually alters the "electrical charge" of that particular area.
Common portable devices nowadays still use the press-type, usually it is completely separated from and installed on top of the LCD (if you look closely to your screen when it's turned off you'll notice tiny dots which is the matrix), that's why sometimes they slide around and you have to recalibrate your touch screen. I hope this makes sense.
KaiserVideoDriver has it correct. That's why the iPhone has such a sensative touch screen. Also, I believe that the resistance based touch screens that our phones use are not capable of registering mulitple touch pionts, which is why Apple had to go the opposite route...in order to facilitate the multi touch interface.
From time to time I try and use my Hermes without the stylus, but I constantly find myself either tiring of the constant finger prints and smudges, or I get aggrevated over the touch screen seeming to have a fit from time to time and register touches wrong. It seems to be calibrated for the stylus (i.e. a small, firm touch point); the larger, spread out touch point of a meaty fingertip seems to drive the screen crazy and cause it to register the touch to either of the upper corners. Infuriating when it closes a program or tries to cancel an SMS on you.

What advantage does capacitive screen give Android? For me it's been HORRIBLE.

New Hero owner here... using it 3 weeks. LOVE the phone, love the 7 pages, love the widgets, love the screen, love SenseUI, HATE the capacitive screen.
Coming form windows mobile for past 5 years, i am expending at least 5x more time and energy to navigate or browse due to this "feature".
I am certain this has been hashed out here before, but I will settle for a short answer, even one that has a laundry list if you like.
All I ask is that you please tell me it has something to add other than MULTI-TOUCH. I could care less about pinch-zoom. Initially when seen on first i-phones it had a wow factor. But very soon on WM, with OperaMini, Netfront, Skyfire, Iris and other browsers, pinch-to-zoom was rendered irrelevant, as all of these browsers provided way more efficient way to zoom in, out, and frame the area of the screen you want to look at. One tap, or two taps, or grab a square positioner (netfront) and tap.
Regardless of marketing, not only were these solutions fantastic, I alos didn't feel any sense of loss.
Now that I HAVE multi-touch on Hero, it's way beyond "yawn". It's more like, "what in the world is the advantage here. all I see is that a capacitive screen is far inferior to a resistive screen for easily 25 reasons. I listed them elsewhere on an XDA "general" forum. Typing: worse. accurate hitting a target: worse, but not just worse, horrible. Tap-hold context menus, require twice as long to press in order to instruct the OS you're indeed pressing for the purpose of holding, vs pressing just to try to make contact. Takes twice the tap impact to activate GO and other action buttons.
So I am dying to hear what is the advantage I have been given on this fantastic $500 USD phone I bought?
2nd question: I am currently using the device straight out the box, with just maybe 25-50 aps or widgets form android marketplace -- which has been fantastically smooth user experience, with perfect degrees of feedback on what access each app will give to the phone etc... very reassuring.
Has the truly amazing world of XDA-devs made some of my major usability complaints above go away, or lessen (after rooting the phone and using a custom ROM)?
Sign me: Baffled and Dismayed in San Francisco
Are there no replies here because this has been previously beaten to death? If so, wold someone please point me to the best thread discussion on this subject matter?
Thank you.
personally, i love a capacitive screen for typing.. as long as you can hit the buttons. For me i have no problem in the horizontal view, but they shouldnt have used a "qwerty" keyboard in the horizontal view, i despise it aha.
for the browsers multi touch, personally i just think its kinda cool, but as you say not very productive.
so really to me, i just love the feeling of capacitive touch screens...when they work of course!
and i know that companies "try" to put capacitive screens on as much as possible (because the iphone and ipod touch are so popular) but you can only really have it on bigger screens. The hero has pretty much the "bare minimum" screen size, and thats why we have some problems!
sorry i didnt really answer your question, just my thoughts but i guess the advantage is (was ment to be) that iphone touch screen experience, but capacitive screens work much better when the buttons have space between them (on bigger screens!)
THis was very helpful thank you. I know what you mean that the glassy smoothness is elegant and competes, I guess, with the look & feel of the Apple handheld devices. But also you seem to be answering my question, which is really the essentiual thing wanted to know:
Apparently there is ZERO added-value that capacitive brings over resistive screen than pinch-zoom... and that glossy glass feeling.
Is this correct, though? Can it really be that the primary reason for running Android on a capacitive screen is its sexiness factor in comparing to glossy look of the iphone?
I know there MUST be threads galore at XDA regarding the value of stylus for rapid composing, and more rapidly scrolling thru a long list on contacts, going into something like 2x or 5x speed flashing through the letters of the alphabet, then slowing down to land on desired contact...
The HTC Leo thread addressed this quite a bit, with both groans and raves for that WM device...

well i used apple as more of an example but i dont think i was very clear before sorry!
Although the screen is glossy and well glass, but i ment that alot of people like having that "touch" not "tap" feel. like how with capacitive you can barely touch the screen and it responds whereas resistive you have to push on the screen. so this makes companies want to use capacitive so there putting it on alot of the bigger touch screen phones

well here is your problem. and I know exactly how you feel, having some PDA and SE P1 also with resistive touch. you'll have to get used to it, there is no other way. it looks similar, like, it's a touchscreen! but difference in technology makes it hard to shift your way of using it
same thing as forgetting clickable keyboards where you can feel edge of each key and you KNOW exactly what you have pressed... and believe me, when you get that feeling with almost microscopic P1 keyboard, first few weeks of brand new high tech on-screen typing makes you smash that phone into wall next to you... but it gets better with time
This is the correct answer. Most people prefer the touch feel of capacitive compared to the press needed for resistive screens.

I moved from an Omnia i900 (WM, resistive screen) to the HTC Hero (Android, capacitive screen) and I am really enjoying the sensitivity of the Hero's screen. Everything is activated with a feather-light touch which really adds to the experience of using a touchscreen device.
On the Omnia, when I tried to halt a scrolling list with my finger, more often than not, I would end up choosing an item instead of stopping the scolling. This got irritating enough that I ended up using the scroll bars most of the time. On the Hero, the scrolling list amazingly stops when my finger makes contact without any unintended item selection. This probably has to do with the sensitivity of the capacitive screen but whatever it is, it works brilliantly.
The only time when I miss the resistive screen is if I need to accurately touch points on the screen due to poorly designed software but this can generally be avoided. Copy and paste could potentially have been a pain with a capacitive screen but the Hero has a trackball which gets the job done quite well.
I agree that multi-touch is nice to have but not critical. It is the sensitivity of the capacitive screen that really makes my day !
IMHO the capacitive screen is one of the best parts of my Hero (the other is not having to use clunky Windows Mobile anymore). It makes it so much more user friendly - and that attribute is what has made the iphone the best seller it is.
It is so much easier to scroll through my emails, texts, contacts, apps etc without accidently clicking on one and opening. And the same applies when scrolling between screens. In my last phone (HTC Touch Diamond) I was forever opening apps and windows I did not mean to when trying to scroll up down or sideways.
And scrolling long lists (I have over 200 contacts) is so easy. Just flick and let it run and then stop it with a finger. Try that on a non-capacitive screen and you are likely to open something you did not mean to open.
And, admittedly after a bit of practice, I have found the QERTY keyboard is no problem at all. It is almost as easy to use with my finger as my TD was with a stylus. And it is even easier when you are in landscape mode.
Still, each to his/her own. If, after giving it some time to get used to, you still don't like it I am sure there are plenty of alternatives out there - it always amazes me the number of different high-end phones HTC makes.

Well somehow you faked me out with your zen-like branch differentiations. I clicked on Soto school first --- and I thought, therefore, that when I clicked on Rinzai, it would communicate more aggressive, harder. But it didn't!

Since the day of my posting this topic, I am starting to feel a shift by gentler tapping. In some cases, yes, I am seeing a difference in better responsiveness.
But I have to admit that this is not always the case. Leading to:

I am starting to get it. Quick illustration: My sim card (my old one from t-mobile wing) happens to be going bad, I just discovered. So I had to swap it out from my HERO back to my WING just to see if I could make a phone call. I had not used the WING (resistive) for a while.
I immediately started making mistakes in the opposite direction. I wasn't pushing hard enough now, and was not activating my selection. So, young grasshopper may be getting the Zen of Capacitive Touch!

I get your point exactly... So, sounds like the people in this forum who have had their HEROs for longer time... must think I am just whining! ha hah
Here are my conclusions thus far:
(a) lighter touch IS helping select more easily.
(b) I began to do as others have said on the soft keyboard-- aim your finger just a nudge above the keys. (because the point of tangency between finger and screen is quite a bit below the tip of the fingernail) (** me thinks they should provide a settings option called "Offset finger touch?" -- and I could select that to in fact shift all the target zones of the on-screen keys slightly below the way they display on-screen, thereby improving accuracy dramatically.)
(c) even with "getting used to" adjustments, the accuracy on the portrait-layout keyboard is still lower on those left edge and right edge keys... And thus I am finding that landscape keyboard is almost becoming required for me (and i have thin fingers!)
(d) On the WM resistive screen, I found that, when using handwriting via stylus, the system really did LEARN to compensate for the style of handwriting of an individual by going thru the alphabet to select the path of drawing each letter that best matches how I write... it absolutely improved handwriting recognition) (AND MAY AS WELL SAY: I miss that the most of all things: I loved being able to jot notes down with stylus and handwriting. I used that daily... SO I miss it)
Similarly, there is an OFFSET ANGLE adjustment on the WM input screen controls, which absolutely made a huge difference: I the natural positioning of a hand and fingers in resting mode on a flat object (a screen) has one's index finger aiming on an angle inward. Thus, the angle adjustment was a smart user interface setting, that I would guess WM came up with over time, as better recognition of this issue surfaced.
(e) I can't expect to use my capacitive screen phone in the lazy ways I used my WM phone with resistive: ie, laying down in bed and tapping out a message to send. When I try to do that with Hero, the angles of finger-contact with the screen are "off" from a standing or sitting alignment of where you hold the device and how you strike the keys. Trying to tap out a note using portrait mode, while laying in bed, and holding phone to its side (or any other awkward position) = probably 10% success rate of hitting the correct keys... Mostly due to that distance-factor between the tip of the finger -- the sight-targeting cross-hairs used for decades in pressing most things that need pressing -- and the underside of the finger, which makes the contact point lower than the tip by a somewhat predictable distance.
I still think there are some ways to go where various compensation settings could nail those issues and bring touch accuracy to much higher percentage, especially in those situations of at what angle you're holding the device in one hand, and tapping with the other hand, is "off", like laying in bed.
(f) Accelerometer: again, when laying in bed (lazy mode), the auto portrait-landscape shifting almost never occurs and i have to hold the phone parallel to the ground and flick it in order to get the layout adjustment, then continue at whatever angle it is I am holding the phone.
(g) WISHLIST #2: (after handwriting/ capacitive stylus is brought to market by HTC, etc) .. is: COntext-sensitive accelerometer.. such that it works in almost any hand-held 3d location, and a 90 degree shift = a shift layout command.

Okay, these are my responses from a Human Factors Interface Design professional background.

Maybe I will have to talk to "Charles", the guy in my nieghborhood in San Francisco, who just happens to be the designer of the original G1 for Google, both in form factor and user interface of android...
San Francisco can be pretty interesting in that way.. you never know who you'll bump into, just like in L.A. with movie stars!

This is actually where I have the most problems.... way more than touching the screen, which I am becoming accustomed to, and now seeing what p[eople are saying about feathertouch responsiveness.
I have not been able to find any settings for trackball responsiveness, the kind you'd find on any laptop for the touchpad or mouse rate of movement -- from super fast to super slow. IS there such an adjustment?
I want to love the trackball, and I am getting better at it. But to me, this is almost just the opposite of featherweight touch on screen. My finger "wants" a more "sticky" or locked-on connection to the trackball, so i can control it better with micro-movements. For me, right now, it is so slippery as to super-slide way out of range, and shifting fields on form data entry, and , when I am using it on a slider bar such as for volume control or color mixing (chnaging color of a background), it's sensitivity is way too wild for even a light touch attempt to control it
QUESTION: I am not yet using any rooted rom from XDA... I am still experiencing the Hero out of the box. So, are there any added control settings that people at XDA have figured out and added to the custom ROMS?
thank you

No ****. what an amazing company... and why I like how XDA-developers built up around HTC... This is a serious question: Is HTC a good stock buy? They seem like moreso than ever, with their new branding and direct-to-consumer marketing campaigns (at least in the USA, big time), ready to leap out as a huge brand in the way Samsung shot up from obscurity many years ago, into a top-5 leading brand of electrionics.

[Q] A43 touch screen

Am I the only one having really poor touch recognition on my A43? Whether I use a finger or stylus, it often happens--about once in five keystrokes or more--that after releasing the touch on an on-screen keyboard, a different key additionally gets registered, sometimes not even a neighboring key. It is very hard to type in a password.
My touchscreen also has this problem. I'll hit one key and it will add another key somewhere entirely else on the screen. Menus will spaz out when I try and scroll through them.
Oh yeah, remember that problem I was having where strange spots showed up on the screen and I had to get it RMA'd? That came back on my BRAND NEW unit. I'm getting sick of the crappy screen on this otherwise great unit =[ Maybe Archos will just give me a refund and I can spend my funds on an unlocked/off contract phone with similar specs.
Sadly, I think this is a hardware issue. I'm not sure there's anything firmware can do besides ignore half of the inputs. But then, you have a non-responsive issue ...
Have you guys tried to calibrate the screen through SDE?
I have a similar issue with my A101, although it's not as bad as you guys describe - sometimes the screen just won't register my touch at all, mostly in the edges of the screen - sometimes I think it's the calluses on my fingers from playing guitar, sometimes I think it's the horrible screen they gave us....

So does anyone not have this problem with an A43?

You might be having better luck because the A101 has a capacitive screen with multi-touch capabilities. They're known to be more reliable than the resistive screens the 43IT's have.

So does anyone not have this problem with an A43?

I have a 43IT, which is why I posted Sorry I wasn't clear. I feel your pain. Also, I suggest using your nail or a stylus, as the pinpoint hardness of either are better than the soft, blob your fingertip makes on the screen sensor array.

I generally use a stylus. The problem is probably due to the way the plastic digitizer flexes which generates ghost movement data on release. A glass digitizer would be much better.
By the way, it is possible to ameliorate the problem slightly in software. I did that in the myKbd app for PalmOS. Basically, you filter out some very rapid motions. It doesn't affect sensitivity in any significant way.
The reason I'd like to know if everyone has this problem is because I'm going to send my A43 in for warranty repairs, and I am wondering if I should include this problem (in addition to the annoying bright 1/4" area on the screen, and the occasional timeouts when writing to internal flash that result in the device hanging).

G9 80 question - viewing angle and touch dead zone

I just bought my 80 G9. Before I start rooting and romming and warranty voiding I thought I should ask in case these are defects:
In landscape mode, is it normal for the viewing angle to be better if the tablet pointed down instead of up? In other words, if I have the screen down on a table and I'm looking at roughly a 45 degree angle 18" away, it's not good. Yet if I prop it up almost vertical in the same place, 18" away, below my line of site, it looks amazing. Head-on it looks kind of ok, but videos and dark images get washed out. (And using it in portrait is odd too - the screen looks good if I tilt it to the left. Otherwise, the screen looks different to each eye).
The second thing I experienced is, there seems to be a touch dead zone in the top middle of the screen, right where the X's are in Chrome for a second or third tab (it takes about 5 taps to finally get one to land on the X). I haven't found any other dead areas.
If both of these are common issues I can live with them.

Do you have a 80G9? Its viewing angles seem to suck
The 2nd issue I have as well, it appeared more in ics so I'm hoping its a software issue and will be fixed soon

Yes, 80 G9.
I'm quickly getting used to the angle.
As for the touch, I ran a drawing program and sure enough there's an 8th inch margin around the whole screen where touching is difficult.
Hi,
i've got the same thing on my 80G9.
After a screen calibration and after the last update, the touchscreen is ok.
The viewing angle is very bad on this tablet in landscape. Try to do a 180° rotation. I only find this solution to watch correctly
Its designed to be optimally viewed using the stand so that's probably why the viewing angle sucks flat and Straight.
I think the dead area is not a dead area its just chrome takes a while to respond due to its huge memory requirements with tabs.
As for voiding the warranty : If you use custom roms from here (XDA) and NOT Official then your device won't be watermarked and won't void the warranty. Just remember to total factory reset/wipe and remove SDE Menu system before you ship it back if it needs a repair.
Psi.

I installed multitouch visual test from the market, and there was a definite dead zone. The taps would be extremely accurate up until you reached 1/8-1/4 from the edge, and suddenly nine out of ten taps would land on the very edge. Tapping on chrome tab buttons was merely a symptom.
So I returned the G9 and exchanged it (I had drove 2 hours to a store to buy it in the first place, and luckily found an excuse to go back within the 14 day return period). I exchanged it, and tested it on the spot. The accuracy of the edges was much better. I'd say nine out of ten taps near the edges were within 5 pixels (whereas in the center they were dead on). Not quite a scientific test, but definitely noticeably better. And tapping on things near the edge like chrome tabs worked 9/10 times.
That was yesterday. I got home, started playing with it, turned the tablet to rotate it, and no rotate. I know rotation worked earlier in the day while I was testing it - it had rotated while in my lap at an almost flat angle. Still I double checked the rotation settings, did a factory reset, upgraded to stock 4.0.6. It's still stuck in landscape mode.
So I'm out. I'll find another excuse to drive 2 hours each way back to the store sometime in the next 2 weeks, and probably exchange it for something else (with any luck the nexus will be out).
It's too bad too. I really liked it. The price was phenominal, the hardware design straightforward, the os non-bloated, etc. From what I read there aren't a lot of problems with the hardware. I just have dumb luck I guess.

I got two A80S tablets and no problems with touchscreen here.
Just to inform you about some features of ICS:
Have a look in the settings...
- Developer options
- User Interface
- Show touches
After activating this option a light spot is shown after touching the screen.
No need for an external tool to check the accuracy of your touchscreen .

Thanks! This certainly won't be my last ICS device, so that's good to know!

Mediapad m5 pro m-pen pressure sensitivity problem

www . youtube . com/watch?v=0Jt1WKymqkM
(not allowed to post links yet)
Hello
I'm using the m5 pro for drawing, but run into an issue with
the pressure sensitivity. The pen doesn't seem to register pressure
below a certain threshold. Then as pressure is increased, suddenly it does. When
drawing, this results in a dotted line, as opposed to a line with continuously
varying opaqueness. See movie above for an example.
Hoping someone can try and replicate this, so I can find out if this is
a design flaw, or a fault in my tablet or pen. Brush settings are quoted in
the movie's description..

in case anyone is interested: meantime I was able to test the same app on an ipad, and it basically shows the same behaviour, though the ipad is a bit more sensitive. There I also see a broken line. So I think its not an issue with the device itself, just a limitation of the software and technology. You cant seem to beat the sensitivity of a siple pencil (lead)...
I find it heavy but sensitive. Any contact with the screen will draw. Android registers even the distance of the pen from the screen and its angles in the MotionEvent traces so I'd say you just need to tweak your app to make it oversensitive.

Yes I also think its due to the app. Unfortunately in infinit painter I cant find a way to change the pressure curves or something. I'm gonna try some other ones..
